Chapter 173 (1/2)
This makes Hou Ying feel very strange.
There seems to be no one in the outer city of the Yangtze River base except the patrol team, which is understandable. After all, there is a strong wind outside. If the outer city is still using tents, it is impossible to live. The flow of people in the middle city is dense, but these people are more nervous than when the Yellow River base is facing the zombie tide. It is clear that the zombie tide has retreated, and the people in the Yangtze River base are still facing the enemy. What is their enemy? What's worse than zombie tide?
With such questions, Hou Ying pays more attention to all the sounds on the ground. Before he gets the answer, the sewers become lively.
Soon after entering Zhongcheng, Li Xuanyuan became very cautious.
Because most of these underground sewers have lost their original function of drainage, they have been specially reconstructed, and the structure is completely different from that of sewers.
After hearing the footsteps, Hou Ying pulls Li Xuanyuan. They turn to the place where the footsteps are most intensive, and soon they see the light source in front of them. They didn't rush close to avoid exposure. After listening carefully for a while, Hou Ying chose to hide beside a wall and stick to it for a long time to make sure that the back of the wall was hollow, and the sound of pulley came constantly.
Li Xuanyuan turned over and stood on his head, making two small holes for observation on the wall with the keel. The wall here is the work of the third level powers. Although it is vulnerable in front of Li Xuanyuan, it is hard to be destroyed by idle people. Li Xuanyuan stretched out his hand and hung in the air. Hou Ying also pulled it up. Hou Ying took a look and found that the passage behind her was really two-way tracks, and the cart glided back and forth.
During the period of energy shortage, the Yangtze River base is very generous. In this passage, monitors and lighting equipment are very complete, almost every 50 meters.
The end of the passage is the place where Hou Ying hears the sound of footsteps a few hundred meters in front, the beginning Hou Ying listened attentively for a long time, and the sound of wind and pulley all pointed to the former site of the laboratory when they came.
No wonder those people no longer need to go through the original doors.
Hou Ying figured this out, and then he and Li Xuanyuan put the two small pieces of metal cut off again, so as not to cause the patrol's attention due to light leakage.
The things transported in those carts are not small clues. Hou Ying and Li Xuanyuan stick their backs to the wall and face down, relying on the mountain climbing tiger to drive them forward. They slowed down and stopped at the corner of the well lit passageway at the junction with the common passageway.
The people in the passage are busy receiving things from the track. They are very busy and have no communication. Hou Ying only hears the voice of two people talking. The tone should be the leader of these people. She constantly instructs these people to send the things from the cart to the corresponding number A1, A2 and other places, and takes the trouble to tell them never to touch the things in the cart.
Hou Ying listened attentively to the tracks of the carts and footsteps, and roughly drew the structural diagram of the passageways and the location of the numbered rooms with the Parthenocissus. There were four ABCD passageways sent by the carts, from 1 to 18, with 72 rooms on the odd side and even side.
But how to get through these people to those numbered rooms is a problem.
Li Xuanyuan made a backward gesture, and they retreated to a safe area. Then he lowered his voice and said, ”let's go through the earth from the top.”
Hou Ying's eyes brightened, and she also whispered: ”are you sure you don't make too much noise? There must be hearing powers here. ” Without Meng hanghai's space attack ability and Li Dong's earth ability, it's hard for the wood ability to be quiet.
Although the helmet has sound insulation function, the two people speak as quietly as possible due to the atmosphere.
See Li Xuanyuan nod, Hou Ying no longer ask. Li Xuanyuan quickly found a breakthrough point. The keel turned into a sharp blade and drew a circle on the wall for people to pass through. The one meter cylinder soil was constantly taken down, and the soil dug out by the vine was suspended in the air, blocking the passage behind him before 50 meters. So repeatedly, about 800 meters forward, Hou Ying suddenly took Li Xuanyuan.
”There's an alarm in the dirt in front of us.” Hou Ying pointed to the direction. If it wasn't for him, as a level 8 auditory psionic, the mechanical sound inside the alarm couldn't escape his ears. Touching the alarm or moving it would probably expose the trace. ”It seems that Chang Hong is not a simple woman.”
Shen Xu, who has been in contact with him, is not only proud, but also not so careful.
The next step was a lot slower. In order to get around the alarm, he played irregularly in the tunnel, and it was difficult for Li Xuanyuan to hold the position even though he was confused.
After hearing the sound of wheels and footsteps again, the sweat on Li Xuanyuan's body has refreshed several layers. Hou Ying first replenished his power energy, and then pointed to a place. They bowed down to continue drilling and stopped at a number room. For the number room, the Yangtze River base pays more attention than the outer passageway. The wall is made by level 4 metal and earth powers.
Li Xuanyuan drew gourd like this and made two small openings on the wall. Instead of looking at it closely this time, they took out a mini monitor from their helmet and put it into the small opening. They used 360 degree electronic eyes to image in the goggles to see the indoor situation.
