A group of people marched up silently, still with all kinds of apprehension in their hearts.

Although it is a hidden tunnel, it is not far from the various floors of the entire building, and there are many places that are common to the ventilation pipes.

I can't see the situation on the floor of the building, but the sound of robot joints "clicking" when countless robots are moving, constantly transmitting from unknown directions to the ears of the special team, making people infinitely nervous.

After walking for about half an hour, nothing special happened.

At this time, they came to the first fork in the road.

This fork in the road is relatively wide. Judging from the structural drawings, the special team should have traveled to one-third of the height of the building.

There are two roads, both of which connect to the vents on the floors.

A vent is so narrow that it can only accommodate one person to crawl through, and the vent is firmly sealed by an iron fence; The other is more spacious and looks like it leads to somewhere in the building.

Shi Fei didn't dare to be careless, in order to have a precise direction, he turned on the flashlight, shone it on the construction diagram, and looked at it carefully.

With great difficulty, he found his position on the construction diagram, the wider fork in the road, which seemed to be a transit room leading to the floor.

Generally speaking, the transfer room is the junction of all the vents, and it is better to look for a route to continue upwards.

Shi Fei was about to make up his mind to tell everyone the direction of the next step, when suddenly, the soles of his feet felt like he had stepped on something, and he stumbled a little, and bent down and touched it with his hand, and it turned out to be a screw.

He suddenly realized something, and quickly told everyone to stop and not move.

Lin Ke leaned over and asked, "What's wrong?" What's wrong? ”

Shi Fei took everyone to the welded vent and shone it with a flashlight, showing that the welding position was not very old.

He picked up the screw he picked up again and handed it to Lin Ke: "Look, this screw, this is a unique accessory for robots. It shouldn't be in this position for no reason. The welded vents can be seen to have been moved recently. ”

Lin Ke looked around vigilantly and lowered his voice: "You mean that the robots know that there is this secret passage, and we entered their ambush circle?" ”

"Nope. Contrary. If this was a trap they had set up on purpose, we wouldn't be able to be here now. But this dark passage, at least this section, has been discovered by robots. The diameter of the welded ventilation duct is very small, and the robot must not be able to enter, so they don't know where the dark tunnel leads, so they simply leave it out. The other exit, which should lead to the transfer room on the floor, can be entered by robots. I guess at the end of the other road, there will be a robot warning point. "Shi Fei Tiao is the analysis of the Dao.

"So, which way are you going?" Lin Ke asked tentatively.

"It must be going to the welded vent. However, once we get inside, someone has to solder the vents from the outside so that our whereabouts aren't revealed too quickly. Shi Fei pulled the iron fence of the vent hard, and welded it quite hard.

Fortunately, among the equipment prepared by the commander for the special squad, there was a small cutting and welding machine, and soon the closed fence was cut.

"There need to be two brothers here to stay and seal the fence. At the same time, we should be on guard here, and if there is any trouble, we must be notified in time. Shi Fei left two special forces, and after some explanation, the remaining twenty people continued to climb in through the narrow vent.

Unexpectedly, the first part of the road was already the most comfortable. After the narrow ventilation pipe, a difficult problem immediately appeared in front of everyone.

The original escape tunnels have been modified into ventilation ducts for the building, and countless pipes have been connected to the various parts of the building.

Drawings of the structure that had been soaked in blood and contaminated with effective markings at the end indicated that the tunnel leading to the top level was clinging to a load-bearing wall of steel casting.

But the intricate pipes divide the entire floor, and it is impossible to distinguish where the load-bearing wall is.

The construction diagram has completely lost its usefulness in this section. The rest of the route can only be relied on by the special forces themselves.

Shi Fei was very reluctant, but he had no choice but to let all the team members disperse, enter the various ventilation ducts, and crawl headlessly in the complex maze like ants, looking for that little hope.

But this maze is really too complicated, and after a few hours have passed, the comrades scattered in the ventilation pipes on each floor have found nothing.

Outside the building, there was a sudden burst of gunfire, and the whole building was shaken one after another.

Shi Fei looked at his watch, and it was already two o'clock in the afternoon! Oops, the siege has begun!

And the task of the special squad, which was not completed before the siege, was, so to speak, a complete failure!

Shi Fei sat down in frustration, his sweat on his head looking very insignificant in the fierce fighting sound of the siege.

Lin Ke came back from one end of the road, but he also found nothing, his face was a little bad, and he sat down beside Shi Fei with a little shortness of breath, gritting his teeth: "Bai Yan, the battle has begun!" ”

Shi Fei almost buried his head in the gap between his legs.

I still failed to carry expectations and complete the task of saving countless fighters.

This despair lasted for dozens of seconds, and he suddenly raised his head suddenly, and his eyes once again glowed with excitement and excitement, as if he had been resurrected with full blood.

"Hackers, we're the closest to the comet right now, we have to attack!"

"However, it's just twenty of us......" Lin Ke's face showed embarrassment, although from the bottom of his heart, he also hoped to have a good fight with the robot.

"Nope! We are now the sharp knife inserted into the blood vessels of the comet, although we have not yet found its brain and heart, but once we attack, this labyrinthine ventilation pipe is our best cover. We can't find a comet, it's hard to find us just as hard as a comet! ”

Shi Fei's words don't seem to be wrong. Once the special forces attack the inside of the building, whether or not they damage the foundation of the comet, they will let the robots in the entire World Light building, and even the comet, know that they are not safe.

As the saying goes, a fortress is easiest to conquer from within.

In this way, even if you can't decapitate the comet, at least let them be like a sharp back, as if facing a big enemy, you can also cooperate with the besieging troops outside and give full play to the power of the special squad.

Lin Ke agreed to the idea of a good partner, and Shi Fei immediately told his comrades who were still scattered around the building about his idea.

The special forces also heard the exchange of fire outside the building, and the original frustration and frustration once again rekindled Shi Fei's plan.

"Okay! We're creating chaos in the building! ”

The team call was immediately overheard by the comet system, and the comet realized that the human army had infiltrated the last fortress, and the entire building immediately sounded alarms.

The members of the special squad, when participating in this operation, no one thought that they would be able to get out of the building alive, and at this time, they took out their weapons in the face of the countless octaped robots that seemed to be extremely nervous coming in and out under the ventilation pipe.
