This made Hou Ying feel very strange.
There seemed to be no one else in the outer city of the Yangtze River Base except for the patrol team. This was understandable. After all, if the outer city was still using tents when the wind was strong outside, it would be uninhabitable at all. The flow of people in Midtown was denser, but these people were even more nervous than when the Yellow River Base was facing the tide of zombies. It is clear that the tide of zombies has receded, and the people in the Yangtze River base are still facing a big enemy, so what is their enemy? Is there anything more terrifying than the tide of zombies
With such questions in mind, Hou Ying paid more attention to all the sounds on the ground. Before he could get an answer, the sewer became lively.
Not long after entering Zhongcheng, Li Xuanyuan's actions became very cautious.
Because most of these underground sewers have lost their original drainage function, but have been deliberately rebuilt, and the structure is completely different from the sewers.
After Hou Ying heard the footsteps, she pulled Li Xuanyuan back, and the two turned to the place where the footsteps were most dense, and saw the light source in front of them not long after. They didn't approach rashly to avoid being exposed. Hou Ying listened carefully for a while, and chose to hide by a wall. She pressed against the wall for a while to confirm that the wall was also hollow, and the sound of pulleys kept coming.
Li Xuanyuan turned over and stood on his head, using the keel spurs to cut two small holes in the wall for observation. The wall here was created by a third-level supernatural being. Although it is vulnerable to Li Xuanyuan, it is difficult for ordinary people to destroy it. Li Xuanyuan stretched out his hand and pulled Hou Ying who was hanging in mid-air. Hou Ying took a look and found that the passage behind her was indeed two two-way tracks, and the cart was gliding back and forth.
During the period of energy shortage, the Yangtze River Base was very generous. The monitors and lighting equipment in this passage were very complete, and they were installed almost every 50 meters.
The end of the passage is a place where Hou Ying heard the dense footsteps hundreds of meters ahead, and the beginning... Hou Ying listened intently for a long time, whether it was the sound of the wind or the sound of the pulleys, they all pointed to the old laboratory site when they came.
No wonder those people no longer need to come in and out through the original door.
Hou Ying figured this out, and Li Xuanyuan and Li Xuanyuan reinstalled the two small pieces of metal that had been cut off, so as not to attract the attention of patrolmen due to light leakage.
The things transported in those carts were a big clue. Hou Ying and Li Xuanyuan put their backs against the wall and faced down, relying on the ivy to drive them forward. They slowed down and stopped only at the corner where the well-lit passage meets the ordinary passage.
The people in the passage were busy receiving the things brought by the track, very busy and no communication, Hou Ying only heard the voices of two people talking, and it should be the leader of these people, constantly instructing these people to bring the carts The things in the carts were sent to the corresponding numbered places A1, A2, etc., and they took the trouble to tell them not to touch the things in the carts.
Hou Ying listened intently to the trajectories of the carts and footsteps, and used the ivy to roughly draw the structure of the passage and the location of the numbered rooms. There are four passages ABCD, from 1 to 18, on the single-numbered side of the carts. There are a total of 72 rooms on the double side.
But how to pass through these people and enter those numbered rooms is a problem.
Li Xuanyuan gestured to retreat, and when the two of them retreated to a safe range, he lowered his voice and said, "We will pass through the soil from above."
Hou Ying's eyes lit up, and she also said in a low voice: "Are you sure you don't make too much noise? There must be people with hearing abilities here." Without Meng Hanghai's space attack ability and Li Dong's earth-type ability, wood-type ability It is difficult to be silent if you can play tunnels.
Although the helmet has a sound insulation function, the two of them spoke as quietly as possible due to the atmosphere.
Seeing Li Xuanyuan nodded, Hou Ying didn't ask any more questions. Li Xuanyuan quickly found an entry point. The keel turned into a sharp blade and drew a circle on the wall for people to pass through. The one-meter-unit cylinders of soil were continuously removed, and the soil dug out by the vines was tied and suspended in the air. In the middle, the passage behind him was blocked without advancing fifty meters. After repeating this, after advancing about 800 meters, Hou Ying suddenly grabbed Li Xuanyuan.
"There is an alarm installed in the soil in front." Hou Ying said and pointed in the direction. If he hadn't been an eighth-level auditory ability user, the sound of the mechanical operation inside the alarm could not escape his ears. Its displacement is likely to expose traces. "It seems that Chang Hong is really not an easy woman."
He has been in contact with Shen Xu before, not only is he proud, but he also doesn't have such a meticulous mind.
The next step into the city was much slower. In order to bypass the sirens, the tunnels were played irregularly. It was difficult for Li Xuanyuan to still grasp the direction in this dizzy situation.
When the sound of wheels and footsteps was heard again, the sweat on Li Xuanyuan's body had refreshed several layers. Hou Ying first replenished him with supernatural energy, and then pointed to a place. . The Yangtze River base of the numbering room is more important than the passage outside. The walls are made of level 4 metal and soil abilities.
Li Xuanyuan drew a gourd in the same way, and made two small openings on the wall. This time, the two of them did not look closely at each other, but took out a mini monitor from the helmet, put it in the small opening, and borrowed the 360-degree electronic eye Imaging in goggles to see what's going on indoors.
This independent numbered room is much larger than they predicted. There are movable patient beds inside, and the occupancy rate is very high. There are nearly 200 people lying on the 300 beds in this room. . They are obviously experimental subjects, with pipes connected to instruments all over their bodies. Hou Ying and Li Xuanyuan didn't know much about these experimental devices. Except for the heart rate and blood pressure indicators displayed on the electrocardiogram for medical use, they couldn't understand other indicators. It seems that they should be some kind of test data model made inside the Yangtze River Base.
But there was no one they were looking for.
Hou Ying and the others speeded up to check the remaining numbered rooms, and there was no missing person from the Pearl River base. When they arrived at a certain numbering room, they happened to meet the person in charge who was tightly wrapped in a white coat and the person who delivered the cart. After closing the door, the person in charge wore white gloves and opened the contents of the cart. It was a small box of test tubes with a bunch of numbers on it. The person in charge took out one and looked at it carefully. Those test tubes were filled with transparent liquid, and the person in charge installed the needle tube at the outlet of the test tube and chose one person to inject.
The method of injection was horrifying. It was injected directly into the human brain, and the person who was injected reacted quickly, convulsing all over, and the eyes that were originally closed suddenly opened and protruded. He was locked up firmly and couldn't move, but it was clear from his facial expression and the degree of muscle tension that he was in great pain.
At the same time, a series of data on the machine fluctuated, and Hou Ying saw that the person's heart rate and blood pressure soared to a level dozens of times higher than that of ordinary people, which would cause sudden death for ordinary people.
He frowned, and it took three minutes for the injected person to calm down and fall back into a coma.
The person in charge concentrated on recording the data on the instrument and seemed dissatisfied with it.
The two didn't stay long and continued to investigate, but after checking the seventy-two numbered rooms, there was no one they wanted to leave. They made up their minds, turned back to the old laboratory site in an authentic way, and chose a place to put the mini monitor. The ivy crawled secretly with the monitor, and the scene Hou Houying and the others saw also changed accordingly.
The laboratory is completely different from the previous place. The passages are narrow and complicated, and when the line of sight advances to a hall, there are more people inside.
These people constantly monitor the panorama of the laboratory through computer monitors, whether it is a confinement room or an independent laboratory or passage. Li Xuanyuan subconsciously simulated the structure of the laboratory in his mind through these monitoring maps of each area, and soon drove the creepers to go to the independent laboratory and the prison room.
An independent laboratory, or more appropriately called an anatomy room. Groups of people in white coats cut open human brains. Their skills are very high, and the people who were cut open are still alive. They are all supernatural beings, and the white coats are dealing with their supernatural being glands. They don’t know how to use them. The supernatural being experimental subjects stimulate their abilities according to their requirements, and the supernatural being glands quickly secrete glands. These people used a certain method to liquefy the adenosine, extracted it and put it into a test tube—it was the test tube liquid that was injected into the test subject before.
Hou Ying pursed her lips and stared at the experiment process, and found that those people were constantly stimulating the experimental subjects of supernatural beings to continuously extract adenoids, and other independent laboratories were also repeating this process.
And Li Xuanyuan finally gained something in the prison cell.
It turned out that the supernatural beings of the Pearl River Base were imprisoned here!
The two communicated in low voices, Li Xuanyuan confirmed that the people at the Pearl River base were not dead, and Hou Ying explained that their superhuman glands were probably still in the process of experimenting with the adenoids they had seen. And it is almost impossible for the two of them to save thousands of people. Although they are not reconciled, they can only go back first and then make a long-term plan.
The two returned from the Yangtze River base with heavy stomachs. This time, they took the same sewer route as before. After leaving the outer city, they were about to return to the ground when Hou Ying heard a somewhat familiar voice.
"Is it here? How to go next?"
"I don't know, we also heard it from others inadvertently, so we can only try it."
"Is it too risky..."
"No matter what, I'm going to give it a try. Boss He, you've helped us a lot. It's dangerous to go. You can't let your people accompany us to take risks for no reason. Go back."
Boss He
Hou Ying raised her eyebrows, greeted Li Xuanyuan, and approached him.
Unexpectedly, I met an old acquaintance!
He Daqing, the bald head, and several fourth-level and five-element supernatural beings from the Pearl River Base!
