Even if you want to drink fresh water directly, it is not possible. It must be filtered or distilled, and finally it must be heated and boiled. The world is already full of crises, but human beings have been developing. In order to survive, human beings have invented many things. Wild survival items include water filters and high-energy compressed biscuits, but the most commonly used ones are fire sources. You know, humans can't live without fire, but they can't always carry a burning flame with them. Preserving the fire is necessary.
Things like lighters have almost disappeared in this world because there are too many parts to produce lighters. The most commonly used one is the fire break. Ma Tao's current ignition tool is the fire break.
Although it sounds a bit technologically backward, after all, fire breakers are the most commonly used objects by ancient people, but when it comes to fire breakers, they are also a very high-tech scientific item. There must be other reasons for its continued development and growth in this world. reason.
Huozhizi is made of very rough earthen paper rolled into a tight roll. It is lit with fire and then blown out. Although there is no flame at this time, red bright spots can be seen faintly burning, just like the remnants of ashes. Fire can remain unextinguished for a long time. When it is necessary to light a fire, it can be rekindled by just blowing. However, blowing is very skillful. It needs to be sudden, short, and powerful, and the air supply must be large. It is used for night marches or night raids, or It was used for smoking hookah in the past, one for military use and one for civilian use. It contains phosphorus and some oxygen-prone substances. When the temperature is high, if you blow it with your mouth or flick it quickly, it will fully contact with oxygen and react violently to burn. The real fire paper is a kind of straw paper that can be easily ignited. In the past, it was mostly used to light cigarettes and make fires in the countryside. It is said that the longest fire paper can last for a year. It is really very powerful.
It took the university less than half an hour for all three tanks to replenish their filtered fresh water before setting off again.
When he got out of the car to get water, Ma Tao felt that there would be gusts of cool wind blowing from time to time in the cave. As the saying goes, there must be another exit if there is convective wind. The weak wind force means that this exit is far away. They should be quite far away.
What makes Ma Tao feel even more extraordinary is the ground here.
The ground in the cave is not as hard as the rock walls on both sides. It is made of soft sand like the road in the cave behind Lao Yang's tool shop, and it is very dry. It is for this reason. Ma Tao immediately guessed whether there might be something hidden in the sand here.
If Ma Tao and the others hadn't been to that cave before, he really wouldn't have thought about it. Now that he has thought about it, there is absolutely no reason to miss it. So, Ma Tao gave up the right to drive the No. 1 tank completely. He handed it over to his sister, and he found out the detector and adjusted it to range sensing and then started to detect a large area. In this way, the traveling speed of the convoy had to be reduced to a speed that could be fully sensed by the detector.
The range sensing of the detector is good or bad. This mode will not miss large metal equipment, but it will not be able to sense some small metals. For example, there will be no response at all to firearms. Although Ma Tao also wants to Measuring every inch of the land in the cave meticulously, but the space in the cave is indeed too wide. If I use my legs to measure it step by step, the time it would take is simply incalculable. The number of days, plus the fact that it is not safe in this cave, is the last resort.
Because this cave is really too wide, both at the entrance and inside, many monsters like to crawl into it. After walking a few kilometers in, Ma Tao and the others were attacked by three laser earthworms. Although Device C discovered it in advance, but the No. 3 and No. 2 vehicles combined still lost more than 100 pieces of armor and got back more than 380 G.
After walking for a while, the cave turned, and a freshwater source that was much larger than before appeared in front of us again, because some of the same green plants as those seen at the entrance also grew on the edge of the lake, but the The road in front of everyone turned into two. One was a cave within a cave at the same bottom. It was so dark below that nothing could be seen. The other was a path that went back for a while and then extended back. Although it is a small road, there is no problem in accommodating tanks.
"Holy crap! It's so big in here! There's even a second floor!"
Xiao Jinzi parked the jeep at the dark entrance to the next level, looked at it, and naturally muttered to himself, but he didn't turn off his watch, so others could hear what he said. In addition, this kid also spoke loudly. Hear it very clearly.
"What to do? Which way to go?"
My sister asked after Ma Tao, who was waiting for the co-pilot, had roughly inspected the area about thirty meters away.
“Go to the trails”
Ma Tao kept staring at the detector. Hearing this, he raised his head and glanced at the road conditions before decisively choosing to go to that path to have a look.
Just kidding, how can we go to the next level before we have finished detecting this level? Besides, if there are several exits in this hole, we may have to come back and detect it again. So, we still searched each level to confirm that there is nothing wrong. Stuff as well.
Not far along another fork in the road, the space suddenly became much wider. A closer look revealed that this was a closed space with no road in front. The location they were in was an oval Tianre cave.
"Wait a minute!"
Ma Tao, who was in the No. 1 tank, noticed that the detector in his hand suddenly jumped when it shot across a certain place. It was precisely because of this jump that Ma Tao shouted to stop.
"What's wrong? Is there something underground?"
Since it was a dead end, the sister who was driving the chariot and was about to turn around suddenly heard Ma Tao's words and stepped on the brakes quickly.
"Brother Tao! Is the detector responding?"
Everyone's communication watches were connected. Xiao Jinzi also heard Ma Tao's words. He was more excited than Ma Tao. The last time the detector responded and found the 105 cannon, this time it may not be anything.
"Not sure yet...I'm testing it again"
Ma Tao stared at the metal detector in his hand and checked it again. In the same way, the display jumped again in the previous place.
"Location, fifteen meters at two o'clock"
Ma Tao found the approximate location and read it directly.
At this moment, the three chariots have just entered through the only entrance and exit. All the fronts of the chariots are facing south. The two o'clock direction mentioned by Ma Tao is actually a little southwest. After all, this oval natural cave is also With such a large area, even if there is an angle deviation of one meter or two meters, it will not be too different.
"Car No. 3 on alert!"
After saying this, Ma Tao threw the detector in his hand directly to his sister and jumped off the chariot.
The position of the No. 3 CMB ambulance happened to block the only entrance. Since there were no other monsters seen in the cave, it was natural to save the last tank to ensure everyone's safety.
When Ma Tao got out of the car, Xiao Jinzi had already begun to spit dirt on the ground in a hurry. He was doing it with his hands one after another, but the efficiency was very low. This was verified when he dug the 105 cannon before. It was still the result of four people taking action.
Seeing this guy digging in the sand like he was beaten to death, Ma Tao suddenly had an idea. He turned around and returned to the No. 1 tank. He took out the pot that his sister had brought back earlier and started digging with the pot. Why don't you? Said, although this thing is not easy to use, it is much better than hands.
After a while, my sister also got off the chariot and followed Ma Tao and Xiao Jinzi to dig together, and then Su Lanyu also got off.
"Brother Tao, do you think there might be a chariot down here?"
Xiao Jinzi was sweating profusely while digging in the soil, but his face was always filled with a silly smile. Maybe it was the chariot that kept this kid in a state of excitement.
"No, the detector shows that there is a lot of metal here, but the area is not that large."
Ma Tao replied while filling the pot with sand.
"Then it's another main gun."
Xiao Jinzi blinked, but he didn't give up, still digging the sand with his hands as if he was still trying his best.
"Maybe it's a pile of scrap metal."
My sister suddenly said something very shocking. The boy who was digging sand suddenly froze in his movements. Ma Tao almost stopped laughing when he saw it.
Fortunately, the ground here is made of fine sand, and for some reason it is quite dry. It is all granular and is quite easy to dig. In about 20 minutes, they dug a sand pit with a diameter of more than three meters and buried it. The things inside gradually came to light.
The thing buried in the sand was really not that big, just a metal box, but everyone knew this metal box and they had purchased it before.
"It's actually the tank's C device?"
Ma Tao picked up the C device in the sandpit and looked at it. He found that it was Nick, which was a good gain.
Unbelieving, Xiao Jinzi dug a few more times in the sand pit with his hands. He even ran to Ma Tao's tank to get a metal detector and checked the location of the sand pit. He found that there was indeed a metal detector in the sand pit. There is nothing left.
"Holy crap! I've been working hard for a long time and I was given a C device..."
A somewhat depressed Xiao Jinzi put down the metal detector in his hand and sat down on the sand to wipe the sweat from his forehead. He then rolled up his shirt to reveal his washed belly and complained while cooling off.
"This is not bad. If I really bury a few useless assault rifle magazines for you, it would be worse than this."
Su Lanyu was also sweating all over from working hard, but the women's tactical clothes were tight and there was no way to expose her belly to cool off like Xiao Jinzi did.
Xiao Jinzi was speechless. Indeed, if it was what Su Lanyu said, Xiao Jinzi would really want to hit him with a piece of tofu.
Fortunately, it wasn't. After all, C-device Nick was still worth a few dollars. If it were just a pile of junk, it would be over.
Ma Tao stared at the C device in his hand without saying a word for a long time.
"What’s wrong with you?"
Su Lanyu turned around and noticed which C device Ma Tao's eyes were always on and asked him strangely.
"Ah? It's nothing. Let's take a rest and continue our journey."
Ma Tao came to his senses after hearing this, then threw the C device in his hand to Xiao Jinzi, turned around and walked towards his No. 1 tank.
"Brother Tao...what's wrong?"
Xiao Jinzi held the C device and Nick watched as he suddenly left. Ma Tao then looked at Sister R and Su Lanyu who were present and said something unclear.
"Who knows?"
Su Lanyu shook his head, then turned and walked towards the No. 3 CMB ambulance.
Xiao Jinzi and Sister R looked at each other, and they turned around and went back to their cars. However, Sister R did not forget the metal detector that Xiao Jinzi took out, and of course, the pot they used to eat. .
"What just happened to you?"
As soon as she entered the compartment of the No. 1 tank combat vehicle, my sister saw Ma Tao sitting in the passenger seat staring blankly at a button in front of him, seeming to be thinking about something.
"Nothing, just thinking about something."
Ma Tao didn't look back, still maintaining his dazed look and replied.
"Do you still use this?"
My sister put down the pot and then raised the metal detector and asked.
Ma Tao then looked back at the metal detector in her hand, then reached out and took it.
My sister shook her head, then patted the dirt on her clothes and sat in the driver's seat.
After all, the space here is limited, and there is no way to complete the U-turn of the three tanks, so the rear team can only change to the front team, and the minibus can take the lead and drive out.
But not far away, Ma Tao suddenly heard the sound of a cannon, followed by a series of explosions.
"What's going on with Sister Han?"
Before Ma Tao could ask questions, Xiao Jinzi spoke first.
"It's okay, it's just a few bomb turtles blocking the road. I've already taken care of them."
Gao Han replied calmly.
The Bomb Turtle usually hides underground. It will quietly approach the tank and self-destruct. When someone approaches it, it will also choose to self-destruct. It will also disguise itself as underground treasures or stones to deceive the C device or metal. The detector and the greedy hunter died together. This thing is very annoying, and the power of self-destruction is not small. But once it is discovered, there is nothing you can do. Not only can the slow-moving bomb turtle not be able to run away, but it will also be easily blown up. If you are around It would be a tragedy if there were its kind or other monsters. Not only did it have to withstand the artillery fire from the attack, but it also had to withstand the damage caused by the explosion of the Bomb Turtle. It was a fool monster that deceived teammates without discussion.
When passing the shattered remains of the bomb turtle that had self-destructed, the hatch of No. 3 car opened. Su Lanyu quickly got out of the car and picked up their G before the convoy set off again.
When he returned to the entrance of the pothole under the passage, Ma Tao started to use the detector to detect whether there were any metal objects in the ground bit by bit. The speed he had just increased had to be reduced to a slow level again. Similarly, Ma Tao Tao's No. 1 tank was at the front again because it was responsible for exploring the route.
Unexpectedly, after coming down, the second underground floor was much larger than the first floor, and it was connected in all directions. There were roads in front and on both sides, and there were also large and small puddles. The bright searchlights of the chariots. A burst of sparkling light shines on the water, which is quite beautiful.
"Which way?"
The detector in his hand did not jump again, but he had to choose a road in front of him. Ma Tao struggled for a while, then looked at the road ahead and pointed.
There are a few things to remember when looking for a route in an underground environment. Never go down to the second floor if you don’t understand what’s going on. Since there is no clear direction, just look for a path. It’s easiest to go straight. Choice, but Ma Tao did not expect that not long after his choice, he would be faced with another choice.
"What should I do this time?"
The sister who was responsible for driving the chariot asked him again because there was actually a pothole at the end of the road that Ma Tao chose, and there was also a slope that could be accessed below. Good guy, this cave actually has an upper, middle and lower part. The third floor is also deep enough. They may not be on the bottom of the sea at this moment. If they follow this pattern, there must be sea water above their heads.
"Holy crap! How deep is this cave?"
Xiao Jinzi also sighed for a while. In his opinion, after going down to the three underground floors in a row, the distance between them and the ground would be at least nearly a hundred meters. If they go down, is it possible that they can reach the underground river under the sea?
"Can't you go down?"
My sister asked again.
"Down"
He was so cruel that he had already come this far, so he just took a look at it. Ma Tao almost gritted his teeth and said this word.
“I don’t recommend going down.”
Gao Han expressed different opinions at this time.
"Why?"
Ma Tao stared at his watch and asked her:
Gao Han paused for a while, seeming to be thinking about what she wanted to say, and then said, "We are too far away from the ground. We don't know the specific situation on this level. It is really a big mistake to go down rashly." risky behavior”
"Then let's explore this layer first."
Ma Tao was not someone who refused to listen to advice. He was about to ask his sister to turn the car around and go back. Suddenly, Nick, the C device of the three tanks, started to warn them almost at the same time.
"Warning! A large number of monsters are approaching"
"Warning! A large number of monsters are approaching"
In the car, Ma Tao stood up from the passenger seat when he heard the rapid siren, but he forgot that he was wearing a seat belt and was pulled back to his seat.
"Turn around! Turn around! Turn around immediately and prepare to face the enemy."
It is really rare for the C device to warn that there is a large number of monsters. At least three monsters appear at the same time before the C device sends a warning. Ma Tao, who was in a hurry, used his watch to call everyone to turn around and looked behind him. Heading into the cave they had just walked through, three chariots were now at the edge of the pit leading to the third underground floor. Except for the gentle slope on the left that led to the bottom, the rest were vertical cliffs. There was no obstruction, but fortunately there was a platform for them to turn around, otherwise there would be nothing they could do.
Almost as soon as the three cars turned around, the sound of sliding sand came through. Listening to the sound, there were indeed a lot of them, and they were moving quite fast.
"What is it?"
In the watch, Gao Han heard the voice sounded familiar.
"It should be a laser earthworm"
After listening carefully for a while, Xiao Jinzi felt that he had heard this voice somewhere before. He thought about it carefully before confirming it.
"Then how many laser earthworms are there... there must be dozens of them..."
Su Lanyu said with some disbelief after hearing what Xiao Jinzi said in the watch.
Ma Tao's face was already very cautious. These bursts of rustling sounds did sound like they were made by laser earthworms when they moved, but as Su Lanyu said, there must be at least dozens of laser earthworms to make such a loud noise. Ah, but this kind of thing is not impossible. When they first set foot on this beach, didn't they experience a scene of countless laser earthworms emerging from the sand? So, dozens of laser earthworms It is still possible for them to happen together, but this situation is quite special.
The laser emitted by a laser earthworm can cause Ma Tao's No. 1 tank fifty armor pieces to lose, the No. 2 jeep to suffer more than seventy armor pieces, and the No. 3 minibus to suffer more than eighty G damage. A single attack by dozens of laser earthworms is enough to consume all the armor plates of Party B's three tanks.
The rustling sounds were getting closer and closer, and everyone's hearts were in their throats, because they could all think of everything Ma Tao could think of, and there was no way to talk about surrender with monsters. Humans and Noah monsters In the war, either you die or I die, or you join and become monsters. Fortunately, the terrain they are in is quite favorable to Ma Tao and the others. The narrow entrance of the cave can avoid the simultaneous attacks of many mechanical earthworms. .
Ma Tao's eyes were fixed on the exit of the cave. Everyone's eyes were looking at that position, just waiting for the first monster to show its head and deal a devastating blow, but waiting, waiting, that moment The sound of rustling became more and more distant when it was closest to them.
"The monster has turned a corner..."
Xiao Jinzi has the best hearing. Ma Tao learned this before when he was avoiding amoeba in Port Port. He was really awesome.
Ma Tao could hear his heartbeat thumping in his chest at this moment, but he could still clearly hear the direction change of the rustling sound in his ears.
"Strange, it did turn a corner."
Gao Han and Su Lanyu could also hear it. Both of them had certain kung fu skills and were not weak in hearing.
"We need to avoid this wave of monsters"
Ma Tao took a deep breath and glanced at the potholes on the third underground floor of the passage behind him.
There is no other way. If you go out now, you are very likely to encounter this wave of monsters. Once you come into contact, it will be a fierce battle. You don't have to guess to know that it will definitely be a battle in which you will injure the enemy a thousand times and lose eight hundred to yourself.
Now that things have happened, going to the third underground floor is indeed the safest decision. Gao Han no longer insists on his previous opinion. After all, the danger encountered with these monsters is definitely much higher than the risk of going down to the third underground floor. .
Changing direction, they followed the slope of the pothole down to the third underground floor. Ma Tao and the others finally set foot on the third floor. Could there be a chariot hidden here? Are there any other good treasures hidden on the third floor? Let us wait and see, will Ma Tao's good luck appear again? ? ? ? ? ? ? ? ? ? ? ?
