After preliminary exploration, it was very easy to demolish the stone wall. After a while, the arrow array mechanism behind the stone wall appeared in front of everyone.
The reed used to launch iron arrows is also an unknown special steel material. Even if it is hit with a hammer, it is difficult to cause it to deform too much.
The bowstring feels like a lubricated ceramic, and without special identification, it is impossible to judge its composition by appearance.
With these two top-level materials, they can only be used to make the most primitive bows and arrows. It seems that in the era of the tomb designer, even if a large amount of high-tech equipment was still inherited, a lot of supporting knowledge reserves have actually been lost.
Under the premise of insufficient population, a tribe can only select the knowledge they consider most important to pass on.
These related knowledge are either violent weapons used to maintain rule, or necessary knowledge used in daily life.
The inheritance of violent weapons will also begin to gradually degenerate into cold weapons due to the gradual attenuation of actual application scenarios.
How can a disposable thermal weapon that burns gunpowder be more cost-effective than a reusable bow and arrow?
When facing low-quality slaves, whether they kill them with guns or shoot them with arrows is actually the same.
After inspecting the arrow array, I found that the underground here was actually a hollow area, which was very different from the solid ground tunnel separated by a wall.
Combined with the overall changing pattern of the previous tomb chamber, this secret chamber housing the one-time arrow rain is likely to be the superstructure area built on the multi-story tomb chamber.
Realizing this, Bai Ning quickly had people start dismantling the bed crossbow here so that more space could be made available for hoisting equipment.
As soon as the mechanism that fixed the bed crossbow was removed, the entire bed crossbow disintegrated instantly, and the bow string that had been tense for thousands of years was broken into small grains of millet.
This phenomenon made Bai Ning think of the anti-disassembly function of some commercial equipment. These bed crossbows should have been regarded as some kind of high-precision things in that era. In order to prevent them from being stolen by irrelevant personnel, It is also normal to design such a disassembly and self-destruct function.
Bai Ning, who had no idea about this, waved his hand and signaled the relevant personnel to continue dismantling them. No matter how powerful these crossbows were, they were still not as strong as an anti-aircraft gun, and the related high-strength bowstrings were probably not as strong as the aircraft carrier's arresting cables.
This kind of thing may have certain application scenarios, but in the current society where materials science is highly developed, it may be a bit useless.
Suddenly, the sound of disintegrating metal suddenly sounded throughout the tomb. Although it was a bit scary, it was not harmful at all.
The tomb chamber is narrow and lifting equipment cannot be installed, so the stone strips can only be broken down piece by piece using fixed cutting methods.
An hour or two later, the three stone strips were transported away, and the space under the tomb was revealed to everyone.
The cold air rushing up from below is even more biting, like standing on the wind of the Siberian cold current in winter.
Even if he is wearing a thermal kit, a bit of chill can still penetrate through the gaps in his clothes.
In such a high-intensity cold wave, the drone has already stopped working, so I can only barely put a strong flashlight in and see with the naked eye.
As you can imagine, wearing windproof goggles originally hindered the field of vision. Coupled with the influence of the cold current, the line of sight could only penetrate a distance of one or two meters, which was the limit.
With the current intensity of the cold wave, you might even feel that this tomb was built in a Siberian cold wave.
"what to do?
Do you need to send someone down to take a look? "
Jiang Yingxue, who had also come down at this time, came over to ask, no matter how cold-hearted she was, she still needed to maintain a cautious attitude in this ice cave where she had a near-death experience.
“The design of this cold current is probably to prevent tomb robbers from directly entering the core area of the tomb by digging shafts.
If someone seals the tomb and blocks the passage of airflow, the cold current may be reduced a lot. "
Bai Ning gave his suggestions, and Jiang Yingxue immediately waved her hand, indicating to her subordinates to follow Bai Ning's instructions.
A temporary wall made of windproof tents was erected, and the entire tomb was sealed again. As expected, the cold current blowing from the entrance of the cave gradually diminished.
It seems that there must be a high-pressure area in the wind source area below. The sealed state of the chamber will only slow down the release process of high pressure, but will not completely prevent it.
The risks below were unknown, and there was nothing worth taking risks. Bai Ning gave Jiang Yingxue a look, and the other party understood instantly.
“Follow the highest reward system.
Who wants to go down?
You can come up again one minute after landing. "
There must be a brave man under a big reward. Jiang Yingxue not only offered a high reward, but also reduced the risk of death to a certain extent, which was considered a good incentive policy.
The people here are doing high-risk jobs. As soon as they heard this, several people immediately stepped forward to take over the job.
After some arrangements, Bai Ning decided to let several people take turns to go down and give it a try. After going down, they would go forward in different directions for ten seconds, and then they could go back.
It was the fairest draw to determine the order. The first bodyguard with the most rewards tightened his windproof glasses and safety rope, and went down along the climbing rope as thick as his thumb.
The light was extinguished quickly, and nothing could be seen clearly from the low-temperature-resistant camera. The fog in front of the eyes seemed to be due to the entry of personnel, which brought a large amount of moist water vapor, so that a thin layer of moisture was formed near the personnel. fog.
After reaching a height of about four or five meters, the bodyguard landed directly on the ground. After sending a signal upward with a strong flashlight, he stepped forward.
The sound of empty footsteps mixed with the howling cold wind came from the entrance of the cave. In such a low lower tomb, the light of the flashlight that was previously penetrated seemed to penetrate into a bottomless pit, indicating that it was also smeared with a black light-absorbing layer.
It's like a black hole of light below. Even if there are any traps set inside, it's impossible to tell with the naked eye.
"The walls around the tomb have a black light-absorbing layer, let him come up.
Go get some smoke bombs asking for help. Maybe you can change the background color here. "
Before this exploration had even begun, Bai Ning stopped the follow-up actions. After receiving the order, the bodyguard who was supposed to receive a generous bonus did not feel dissatisfied at all and took action immediately.
Not long after, several white smoke bombs were brought over, the safety was removed and thrown into them, and the hole was sealed with linoleum, but a large amount of smoke was still blown out.
After the smoke bomb burned out, I opened it and saw that the structure of the underground tomb was much clearer with the white powder rendering. However, due to the cold current, the smoke was mostly concentrated near the entrance of the cave and was not fully spread.
"Go on and serve."
Jiang Yingxue ordered, and the exploration process that had been put on hold started again.
The result after a few minutes was very surprising. After all this hard work, the result was just an empty secret room.
Except for a vent that constantly blows out cold currents, there are no traps or traps inside.
Seeing this, Jiang Yingxue instinctively wanted to go in and take a look, but was stopped by Bai Ning.
"Like you guys from before, hang a few rocks down and block the wind tunnel."
After being stopped and hearing Bai Ning's order, Jiang Yingxue was also a little stunned.
Could it be that Bai Ning found something wrong with that air duct?
With such doubts in mind, Jiang Yingxue squatted beside the cave entrance and waited quietly for the follow-up results. The stone was not heavy, and with the cooperation of several people, the wind outlet was quickly blocked.
For a moment, there was even an illusion that the whole tomb was suddenly getting warmer.
Seeing that nothing unexpected happened, Jiang Yingxue glanced at Bai Ning and prepared to turn over and descend along the rope, but was held down by Bai Ning again.
"People below, come up quickly.
Don't panic, you have enough time. "
Bai Ning gave a faint order, which instantly made everyone tense up, and several people in the lower tomb even trembled.
No one dared to question the danger signal Bai Ning sent out. No matter how casually he said it, everyone knew that this kind of rhetoric was just to prevent the team from being in chaos.
There are even some people with more lively thoughts who have concluded that this is Bai Ning's deliberate method. He did not tell them the danger in advance just so that people can go on willingly, do the test without knowing it, and become cannon fodder.
After verifying the blocking of the air duct, the mechanism in the entire mausoleum will undergo huge changes.
Regardless of the cause, it is completely unknown how much safety time they have left and whether it is enough for them to escape in time.
Even if there were casualties in the end, it could all be attributed to accidents. They all made money by working hard, and no one could complain.
Your life is your own, and you bear the risk yourself, so the following people reacted very quickly.
Although the first few steps were a bit embarrassing, fortunately, several of them were well-trained people. While running hard, they exchanged a few words and quickly determined the order of rapid up and down.
When several people came up panting, they found that there was no movement in the lower tomb, which was very embarrassing.
Did everyone think too much and make a false alarm?
"how……"
Just as Jiang Yingxue asked, there was a "rumbling" sound in the lower tomb, interrupting her words.
After the loud noise, the cold current that had just slowed down surged out again, causing everyone to shiver subconsciously, not knowing whether it was because of fear or cold.
"It seems that easily changing the inherent structure of this mausoleum will cause a huge backlash."
Bai Ning looked at the broken stones in the tomb and an iron arrow shot out of the wind duct, and commented casually.
Judging from the current results, this air duct is obviously not a pure air duct, and the space behind the air outlet is much larger than expected.
Even if you think about it a little more seriously, behind the stone wall at the wind outlet, there may be a large number of heavy crossbow arrows hidden, waiting for the tomb robbers who will subsequently dig into the wall to be beaten into bloody gourds.
