Chapter 680 Entering the Base
Yu Yishan took a closer look, and finally saw the difference between the rocks used as vents and other rocks.

The rock in the vent is naturally man-made stone, and its appearance is no different from ordinary stone.But these rocks are very large, with several openings on the surface, or several unfathomable potholes, which seem to be naturally formed due to weathering.

When ordinary people see these cracks and potholes, they will only feel that there are certain creatures living in them, such as snakes and scorpions.They will definitely not be interested in this kind of pitch-black pothole, let alone reach into it to test something.

Of course, no one would come to such a place to study these broken stones.

Yu Yishan put his ears close to these stone holes and listened, and he heard the whistling wind coming from inside.This may not seem strange to ordinary people, because you can hear the whirring wind from inside if you take a conch.There are many potholes on this kind of stone, so it is not surprising that it makes some noise.

"How the hell...how did it get in?"

Yu Yishan looked at the big rock in front of him, and murmured in his heart: "Drill a hole in the rock? Get in?"

As an artificial intelligence, Unit One couldn't help but want to curse MMP.

"Boss! There is a ventilation shaft under this stone, you just need to move the stone away."

"Boss...I like this title."

Yu Yishan let out a breath, and then pressed his hands on the big rock.Then, he seemed to think of something, and asked again: "Is there anything like monitoring here?"

"Yes, but you don't have to worry, Boss. I've already taken care of things like monitoring for you. You can rest assured that it's just destruction."

"That's good."

Yu Yishan felt relieved, and with a vigorous effort, he easily moved the big rock in front of him to the side.

Under this big rock is indeed a large well with a metal structure, and the flow of air can be clearly felt, which proves that this is indeed a ventilation duct.

There is a well edge around the wellhead to prevent the falling of large sandstones.The bottom of the big stone covering it was also hollowed out into a circle, which just fit over the mouth of the well.Looking at the design of the potholes on the stone, the holes extend downward from the inside to the outside, which can completely prevent rainwater from pouring into the ventilation shaft.

If you look closely, there are filter screens installed inside those potholes, which can prevent things like snakes, rats and ants from running into the ventilation shafts, polluting the air and hindering "traffic".There is also a fan unit behind the filter, which seems to be used to clean up dust.

interesting.

Yu Yishan jumped into the well, and saw that there was a quite spacious passage below, wide enough for people to stand and walk.

The cold wind blowing head-on could be clearly felt in the passage, so Yu Yishan couldn't help but looked into the passage a few times, and found that there was actually a light installed in the passage, but the light was off at this time.

"Can you turn on the light?"

"no problem."

The visor of the battle suit naturally has a night vision system, and the No. [-] unit also has a lighting function, but Yu Yishan thinks it will be better to turn on the lights in the passageway.

After turning on the light, the vision is much more comfortable.

Yu Yishan took a closer look at the situation in the passage, and found that there were not only lights in the passage, but also monitoring and other infrared sensing devices.But these devices have been blocked by the No. [-] machine to tamper with the information, and now they can only be regarded as decorations, barely useful.

"Is such a spacious passage reserved for the cleaners to come in and clean?"

Yu Yishan began to stride forward along this ventilation duct, following the direction set by No. [-] unit.

Although there is a filtering device on the big rock outside, there is still a shallow layer of dust accumulated in the passage.It seems that even if someone cleans these ventilation ducts, they won't clean them too frequently, and Yu Yishan doesn't need to care about leaving footprints and being discovered.

There is not only one vent in the ventilation shaft, Yu Yishan walked all the way, and saw several big stone entrances like the one just now, and the cool wind whizzed one by one.

Soon, Yu Yishan came to the end of the passage.

At the end is a large fan, the leaves of the fan are spinning happily, blowing Yu Yishan in high spirits.

The fan is attached to what appears to be a door frame, which appears to open.

Of course, it doesn't matter whether it looks like it or not, just ask the No. [-] machine for such things.

However, before Yishan asked, there was a light click on the door frame.Yu Yishan was taken aback for a moment, then came to his senses, stretched out his hand and pulled the door frame open.

"It's really convenient... There is such a convenient passage, why do you need to go through the gate?"

Yu Yishan couldn't help expressing emotion, then walked into the door, closed the door casually, and let the big fan continue to ventilate.

No. [-] machine proudly said: "You have my assistance, otherwise, you wouldn't even be able to get in that big rock so easily."

"The big deal is that I'll tear them apart with brute force. It's impossible to not get in even though there is a hole."

Yu Yishan drove more easily.

Next is the downward shaft with ladder poles for climbing.But Yu Yishan didn't need this kind of thing, he jumped down, his body floated in the air, and began to descend slowly.

There are also fans in the shaft. Except for the electric door lock, it can only be opened mechanically from the inside. Without the assistance of the No. [-] machine, it is difficult to pass these fans.

However, this ventilation duct originally left room for the cleaners to operate, and it is not impossible for other agents to pass through smoothly.The real trouble is actually the big rock outside. Most people can't find it at all, and even if they find it, they can't move the rock away.

Unless it's a crane.

However, there are monitoring equipment in the area near the base, especially near the entrance of the passage. If you drive an excavator blatantly, you may be hit by an inexplicable rocket.

Keep going, keep going down, I don't know how many horizontal shafts and shafts, and how many wind turbines I have passed, and I can't tell the direction of Yu Yishan. Then the No. [-] machine reminded: "I have entered the third underground floor. Now there are two routes to choose from."

Yu Yishan lifted his spirits: "Say."

"The first route is to continue to advance through the ventilation ducts, but the following ducts are relatively narrow, and you need to take a crawling forward posture. The second route is to enter the personnel activity space of the third-level base, and use the stealth method to close to the destination."

The classic scene in the movie immediately appeared in Yu Yishan's mind. The agents were crawling in the narrow ventilation duct, sweating profusely, and dizzy.

He made a decisive choice: "The second route."
