Hearing this, Zhang Xu frowned and felt an inexplicable uneasiness in his heart.
Teng Youyi and the others placed the fuel tank near the exit of the base and drew up a plan. After many twists and turns, they finally arrived at the source of the zombie gathering.
Since the entire underground city was built very early, its structure is slope-like. This structure cannot effectively establish a foundation, and will also be damaged with the movement of the earth's crust.
Yin Liyan and the others walked all the way, and the deeper they went underground, the higher the temperature there would be. Almost every 100 meters deep, the temperature would increase by about 3 degrees Celsius. The city was more than 800 meters long, and it was about 40 degrees Celsius. .
As time went by, the load-bearing columns became stronger and stronger, supporting the metal dome.
The zombies were getting bigger and bigger, and it was impossible for them to hide completely. Fortunately, the zombies were still the same as before. Even if they found the team members who were accidentally exposed, they ignored them and continued to walk towards the deepest part.
Everyone walked carefully and did not rush for success, because they did not dare to bet on what these zombies wanted to do.
Without maintenance personnel, all the items in the underground city here began to become moldy and damp. Because this is a coastal area, there are already a lot of water droplets in the air. Without the staff to regulate the temperature and humidity, the place became even more dilapidated.
The musty smell around them was a bit pungent, and the mist hindered their sight to a certain extent, which made everyone feel a little reluctant to retreat. However, since they were almost at the end, they gritted their teeth and persisted.
People are curious, and when they go deep into the city, they realize that they still underestimate the number of zombies. Just imagine how terrifying it would be if tens of millions of zombies were crowded together.
They are next to each other. Due to the sloping terrain, the deeper the building floors are, the higher they are. The depth is 834 meters vertically downward from the ground surface, but the actual length of the stairs downward is not this number. It is 1679 meters in total. meters long.
The darkness accompanied by the screams of the zombies made the entire team tense to the extreme. They did not dare to use the light sticks in their hands casually. With only the sliver of light and the eyesight of the evolvers, everyone walked through the steel jungle as if they were blind. Cross the river.
Soon, they came to the source of the zombies. A bottomless pit gave them the most direct impact. The entire vertical alloy wall there actually broke.
The zombies inside did not crowd in. Instead, they seemed to line up in an orderly manner and stood outside, which was completely different from the signs of chaos outside.
I heard that Xu's face was a little ugly. According to the points they recounted, it was enough to show that there was a high-level zombie in this underground dead city.
The previous Zombie Tide Zombie King Spirit Destroyer in Zhengzhou Base was already approaching the threshold of level 20. As far as Zhang Xu was concerned, he still had to be more cautious when dealing with it. He had only led less than 10 million zombies.
On the other hand, here, there are more than 70 million zombies in total. If there was a zombie king controlling them, just imagine, it would be terrible. Zhang Xu's expression became a little serious. This is a dangerous place and must be withdrawn as soon as possible.
"What happens after that?" Zhang Xu poked his head out of the window from time to time to see if any high-level zombies were approaching, and then asked casually.
"We thought it was very hidden at the time, but we never thought that a zombie gecko appeared on the ceiling. It opened its big mouth and rushed towards us..." At this time, Yin Liyan stood up slowly while holding on to the wall, his eyes like As sharp as a falcon, he looked straight at Zhang Xu.
Zhang Xu also seemed to be fine and leaned against the window without saying anything, gesturing for him to continue talking.
Yin Liyan was also very decisive at that time and cut off the zombie gecko's head with a broad knife. Even though his team had seen zombies along the road, they were not aggressive at all, but he did not relax his vigilance like others.
After everyone was shocked, they decided to retreat. Just when they were about to discuss it, a thunderous roar completely shocked the entire group of corpses.
They also knew that they were completely exposed and were in danger. Everyone reacted quickly and turned around and left immediately.
There is also an advantage to having too many zombies, that is, it is difficult for high-level zombies to catch up with them. After all, it is similar to speed-type zombies, no matter how powerful they are, they cannot fly out and bite people.
It can be said that there are almost no zombies in the form of animals. All the zombies are squeezed here and there. Even the tall and powerful zombies cannot push away the zombies around them.
So far, they had not even seen the appearance of the Corpse King, and they had already been scattered by the tide of corpses.
Although they were all elite evolvers and their escape methods were excellent, facing so many zombies, they eventually fell down one by one.
Speaking of this, Yin Liyan looked a little sad, and Zhang Xu tapped his chin. According to what they said, the Corpse King did not pursue him.
It stands to reason that if the zombie king wanted to kill them, the people in this team would not survive at all. The zombies only need to give way to a road, which is enough for the fast zombies in the zombie group to intercept the team members. Obviously it did not do this, so why did it Will Yin Liyan and others be let go?
After all, humans have the greatest desire to hunt zombies. It may be that human genes have a special attraction to them. This is also what puzzles people like Delman and Zhang Xu.
Alpha virus, the weakened version is a zombie virus. It is one of the foods of the Mansha planets and is also used by many civilized creatures.
Of course, the source of all this is from a top technological civilization, the Owen Guy Civilization. Why did the genetic food they developed cause such a situation? This still needs to be verified by Daleman.
Zhang Xu suddenly froze on the spot. When he recalled this incident, the more he thought about it, the weirder it became, but he forgot something. Now he knew a huge problem!
If humans successfully go outside the solar system and face alien creatures with Alpha viruses in their bodies, will they choose to eat humans? No, exactly can they control it?
Zhang Xu felt that there was a high possibility that they could not control it!
According to Delman's description, the master messengers who can destroy the first few low-level civilizations on the earth must have very good means. They may also use genetic technology to transform the human body, making the human body more vulnerable to zombie viruses. Delicious and more attractive!
This guess is not groundless, what if it is?
Even if humans are lucky enough to escape from the solar system, once they encounter other alien organisms that feed on the Alpha virus, the virus will induce these organisms to attack these refugees who escape from the solar system, and use other civilizations to eradicate them!
At the same time, Zhang Xu also concluded that the doomsday zombies this time probably have nothing to do with the previous messengers who destroyed civilization. How could they go to such trouble to destroy a civilization?
Many weapons can wipe out fragile human civilization in an instant. Daleman cited many examples, such as space weapons, dark matter, antimatter, etc. Humanity's knowledge in this area is not even scratching the surface in front of them.
Instead of thinking so much, Zhang Xu just wanted to figure out why this corpse king didn't go after Teng Youyi and the others. Everyone is curious, and even being bruised and swollen cannot stop their desire to explore.
"What!...You're crazy!" Teng Youyi's eyes widened and she looked at Zhang Xu's knife-cut face in disbelief. She deliberately lowered her voice, but it was still harsh enough.
"It seems I can't persuade you anymore..." Yin Liyan's injuries are no longer serious. He had lost too much blood and gradually improved with food, and his complexion changed from pale to normal.
Zhang Xu nodded and resolutely said: "My mission is to find you and rescue you. I will send you to the exit in a while. If you can take the fuel tank, take it back. If you can't take it back, find someone to move it back."
"When you two go back, just tell Uncle Teng my name. I just want to see this corpse king!" Zhang Xu chuckled, with a relaxed expression on his face, not afraid of the countless corpses downstairs.
That's right, Zhang Xu wanted to explore the status of the Corpse King.
The Corpse King is not chasing them, maybe he is recovering from serious injuries, but this situation is obviously impossible. After all, there are tens of millions of zombies around him, how can he be injured.
There is also a possibility that the original mental destroyer had too much weight on his brain and was unable to move. Now his whereabouts are unknown. This is also a possibility.
What may worry Zhang Xu the most is genetic transformation. Each biological gene is unlocked every 10 levels. It will be very difficult to jump through this stage. If this was the case, then it would be normal for this corpse king not to pursue him.
Anyway, Zhang Xu wanted to find out what was going on. If this corpse king was in the critical stage of transformation, dealing with it at this time would be considered as minimizing the harm in advance.
In a blink of an eye, Zhang Xu sent Yin Liyan and Teng Youyi to the exit. They had nothing to persuade them. After all, they had known each other for a short time. Since they could make it out alive, they would naturally cherish this opportunity.
After sending the two people away, Zhang Xu could finally show off his talents.
He soon went deep into the center of the city. His lonely figure was alone in a metal building, his eyes staring into the distance. The dense zombies were like a big net, invisibly covering the underground pit.
A large hole was opened in the metal wall, only more than 6 meters high. The hole was very deep and pitch black. His night vision device alone still couldn't tell anything, but this had attracted Zhang Xu's deep attention.
If it were outside the city, random steel and concrete would become very fragile in Zhang Xu's hands, but Zhang Xu, who could explode dozens of tons of power, was powerless against the metal walls of this underground city.
The underground city must be composed of three or more layers of metal walls, which can be several meters thick. The outermost layer is the most tough and corrosion-resistant, the second layer is the energy-absorbing layer, and the third layer is the transformation layer.
The underground environment is no safer than the surface, and is relatively more dangerous. The closer to the continental plate, the more intense the underground activities are. In the event of natural disasters such as earthquakes, the metal walls of underground cities must withstand powerful forces of hundreds or even thousands of tons to ensure the safety of underground people.
Therefore, it is currently impossible for Zhang Xu to destroy the metal walls of the dungeon. It is precisely because of this that it can better express how terrifying this zombie king he has never met is.
