Catastrophe

The unidentified visitors in the underground tunnel and the exoskeletons that were silently lost made the thugs headed by the beards feel a huge threat. Perhaps because of the particularity of their profession, they were very sensitive to the smell of danger. , Under the circumstance that the identity of the enemy is doubtful, the personnel are unknown, and the whereabouts are unknown, Beard resolutely gave up to stay in this place of right and wrong, and quickly led his subordinates to escape the area and disappeared into the intricate underground tunnel. .

At this time, Ning Zhe, who was the initiator of the incident, competed to eat the compressed biscuits in his hand in a corner one kilometer away from the place of theft.

He was a little worried.

When I came in by myself, I followed the metal thugs in. It was fine when I came, but now I can't get out.

From the moment he took the exoskeleton, he knew in his heart that as long as something was lost, the thugs would definitely follow the clues to investigate. If he returned the same way, he would definitely destroy the organs left by the thugs. , his identity has to be revealed in an instant, so if he wants to be safe, he must choose another way to leave, but he entered the underground world for the first time, and he has no understanding of this place. If he wants to find other exits, I am afraid he can only choose luck, and Once you get lost and you can't even find the way back to the sorting plant, you'll be completely fucked.

Ning Zhe waited in the hidden place for about two hours, shook his watch with a flashlight, and felt that the beard and others must have gone far away at this time, so he picked up the other three sets of exoskeletons and started to go out to find a way out.

According to Ning Zhe's original plan, he was going to hide all the exoskeletons in the tunnel and find a way to get them back, but after thinking about it, he still felt inappropriate. After all, he didn't know much about this place. If he kept going back and forth like this, The longer the delay, the greater the risk factor. In this case, it is better to bring the exoskeleton and find an opportunity to leave directly.

The underground network of the fortress is far more complicated than Ning Zhe imagined. He thought he could get around in a few hours, but after seven or eight hours, he was still wandering around like a headless fly. Although some marks will be left along the way, but slowly those marks have begun to overlap.

What was even more unexpected was that this underground world actually had three floors in total. It was built like an ant's nest. Sometimes people were still on the upper floor, but they turned around and turned to the lower floor. He faintly felt that this The construction of the underground fortifications is so complicated, and there are many inductive fork roads. It is also a kind of protection. The purpose is that when a war occurs, even if a team other than Pei invades the underground fortifications, they will be detoured. Eight elements.

The endurance performance of the thug's exoskeleton in a passive state can indeed save Ning Zhe a lot of energy. At this moment, he has four batteries on his body. Except when climbing up and down, the power is turned on. At other times, he relies on passive support. Yes, so it's equivalent to walking around for seven or eight hours with something heavier than several tens of kilograms.

At seven o'clock in the morning, Ning Zhe had been in the tunnel for a whole night, and finally left the trapped area. At the same time, he found a way to identify his way, that is to follow the pipes of the water pipes.

These pipes themselves transport water. As long as you follow the pipes, you will definitely be able to reach the terminal or the water station. In the area where he was before, all the pipes finally entered the wall enclosed by concrete, and now he is in The area should be dedicated to repairing drainage pipes. There are at least hundreds of pipes on the walls on both sides. The thicker ones are close to one meter in diameter, and the thinner ones are only about the thickness of an arm.

Lying on the side of the pipe and listening to it for a long time, Ning Zhe finally determined that many of the water pipes in this place had water flowing, so he chose a pipe with a moderate diameter and started to move along its trajectory. Ning Zhe did not understand water supply. But you can probably guess that the thicker pipes should be used to withstand greater water flow and pressure, and they must be supplied by the administrative districts farther away, while the thinner pipes should lead to nearby water stations.

After having a direction of travel, Ning Zhe began to follow the path of the pipeline, followed in the tunnel, and walked out for about two kilometers. There was another wall in front of him, and all the pipelines were built into the wall. , only one turned to a small fork in the road. Ning Zhe took a few steps there and saw a staircase that climbed up. As the only entrance, he could only choose to continue.

After climbing the stairs, there was a long, long pipe in front of him, and there was a disgusting stench coming out constantly, but Ning Zhe was overjoyed. Those smells could come here, indicating that the end of the tunnel There is a surging air flow, that is to say, Ning Zhe is already close to the surface exit.

Ning Zhe, who had been trapped underground all night, had a strong belief in survival at this moment. He simply disassembled the other three sets of mecha and tied it behind his back, directly turned on the power of the exoskeleton, and climbed forward along the tunnel. The length of this pipe is about Two or three hundred meters, the further you climb, the heavier the stench ahead, but in Ning Zhe, it smells like freedom.

Soon, he stuck his head out of the pipe. In front of him, there was a small space similar to an air well, with a staircase that continued downward. When he was halfway down, he could already hear the sound of water flowing. Ning Zhe drilled out of the air well. After that, I swayed it outside with a flashlight. The outside of this air shaft is a cross-section of one square meter, with drainage grooves extending far from both sides. Sewage constantly flows on the ground, and there are vegetable leaves, rice grains and hair floating on it. Yes, it looks like sewage discharged from residents' homes.

Being close to the residential area meant that Ning Zhe could return to the ground soon. With the support of the exoskeleton, he began to move forward quickly along the pipeline, ignoring the mud sticking to his body.

About ten minutes or so, UU reading www.uukanshu. comNing Zhe had already seen the light shining into the pipe from the front, and moved faster, and soon saw a rainwater manhole cover made of a large iron grate with blue sky and white clouds above.

"call!"

Seeing the clouds in the sky, Ning Zhe breathed a sigh of relief. After waiting for about 30 seconds, he made sure that there was no sound from above. He pushed open the rainwater well cover and drilled out the probe.

"what?"

As soon as Ning Zhe got out of the sewer, he made a puzzled sound, because at this moment there was a long artificial leather seat in front of him, and there were also small lockers around it, especially when it was still winter, the temperature outside should be It was minus ten degrees, but the location he was in was very warm.

At this moment, Ning Zhe is very strange, why is there such a high temperature in the open air, and there are so many things around, aren't you afraid of losing it?
