After removing these two steel bars, Lin Cheng motioned to Lin Yongjian below to take Coke to hide away, and then put his hands on both sides of the outdoor unit, and at the same time, his arms violently lifted the bulky outdoor unit of the air conditioner!

"Booming ......"

As the outdoor unit was completely dismantled by Lin Cheng, the exterior wall that had been connected to the outdoor unit for a long time also sprinkled bursts of dust, and after blowing away the dust floating in front of him, Lin Cheng carried the outdoor unit and walked down slowly.

He was actually going to throw it down directly, but considering that the size of this outdoor unit was too big, and the noise would be too big if he dropped it, he decided to slowly lift it down.

"What's that?!"

Before Lin Cheng could walk down the ice ladder, Lin Yongjian, who was watching with his head raised below, suddenly exclaimed, pointed to the exposed place of the outdoor unit of the air conditioner and asked urgently!

And Lin Cheng frowned after hearing Lin Yongjian's exclamation, and hurriedly put the outdoor unit in his hand in place, then turned around and ran up!

"It's ......"

After returning to the top again, Lin Cheng looked at the huge dusty stainless steel iron net that appeared in front of him, and his heart suddenly flooded with a little joy!

Originally, he just tried to carry away the outdoor unit of the air conditioner with the heart of Ning Kill, and he didn't think that the vents of the shelter would be opened in this position, after all, as Lin Yongjian said before, this position was too conspicuous.

But the situation in front of him taught him that sometimes you really can't take it for granted, after all, you can never be prepared to figure out everyone's thoughts.

"I can't believe that the location of the vent will actually be located here! The designer who designed this link is really bold enough......"

At this time, Lin Yongjian was also emotional, he had done a lot of projects with his father before the end of the world, but he had never seen such a vent designed.

"Okay, now that you've found the vent, don't talk nonsense, it's ......"

After trying to press the hardness of this stainless steel iron mesh and making sure that he didn't need to use much force to disassemble it, Lin Cheng waved his hand and interrupted Lin Yongjian's emotion, "You and Coke will stay here from now on, I can go in alone, if there are too many people, it is easy to make trouble, which is not conducive to sneaking in." ”

"Huh? But ......"

Seeing that Lin Cheng was actually preparing to go down by himself, Lin Yongjian was shocked and wanted to say something, but after thinking about it again, he found that if he really wanted to sneak in secretly, this was indeed the best way, so he didn't say more, nodded and agreed.

Seeing that Lin Yongjian didn't say anything more, Lin Cheng explained a few words to Coke who was squatting below, and then turned around and began to dismantle the iron net.

"Click...... Click......"

It didn't seem to be worried that this location would be discovered at all, this vent iron fence was not too complicated, Lin Cheng used a long sword to cut off the steel bars used to fix it around and easily dismantled this iron fence.

Glancing at the dark hole inside, Lin Cheng sniffed lightly with his nose, and found that the air inside was not abnormal except for a faint musty smell, so he nodded to Lin Yongjian and Coke below, turned around and got in.

After drilling into the ventilation duct, Lin Cheng took out a flashlight and shone it in front of him, but found that there was no road two meters in front of him, but after thinking about it, the shelter was located under the building of this research institute, and the ventilation duct naturally had to be opened all the way down.

This ventilation duct was very spacious as they had speculated before, and the underground shelter must not be small, but in the end, it was only a ventilation duct for ventilation, and it could not allow Lin Cheng to travel straight, so he could only lie down and slowly move forward, just to avoid making too much noise.

After crawling to the corner a few times, Lin Cheng stretched out his right hand and pressed it on the ground, and he heard a series of slight freezing sounds coming from the ventilation duct below!

After summoning the ice crystal handle, Lin Cheng did not rush down, but pricked up his ears and listened carefully to the movement below for a while, and only after making sure that there was no sound did he get up and slowly crawl down.

"Rustling ......"

In the straight downward ventilation duct, there was no other sound except for the climbing sound that Lin Cheng deliberately suppressed, it was as quiet as a tomb, if there was no flashlight, this dim and cramped space was easy to make people fearful, this feeling of déjà vu made him think of what happened in the Phoenix Mountain cave for the first time.

Shaking his head to throw this not-so-good memory out of his mind, Lin Cheng gradually began to speed up, because he just used the flashlight to shine down a few times and found that he couldn't see the bottom at all, if he kept descending at such a speed, it was estimated that he wouldn't be able to get to the bottom when it was dark outside.

After climbing in the ventilation duct for nearly half an hour, Lin Cheng suddenly heard a "bell" sound, and at the same time felt that his feet were solid, and he finally climbed to the end.

After going down to the bottom, Lin Cheng bowed over with difficulty and took the flashlight again to shine around him, but suddenly found that this ventilation duct located at least 100 meters deep underground actually led to four directions!

"What is this? Show that your underground shelters are in all directions? ”

After seeing this scene, Lin Cheng couldn't help but complain in his heart, this completely disrupted his plan, and he had to choose one of the four passages to move forward.

Frowning and thinking for a moment, Lin Cheng finally couldn't help but sigh, and secretly said that since the matter had come to this, he could only take one step at a time, and it was a big deal to wait until he found out that he had chosen the wrong channel and then returned.

Randomly chose a passage on the left-hand side, Lin Cheng bent down, put the flashlight in his mouth and crawled forward directly, but since this was already within the scope of the underground shelter, his movements became very light and light, even if someone below estimated that it would be difficult to hear any sound.

As he crawled forward, Lin Cheng had been listening to the movements around him with his ears pricked up, expecting to hear a few words of conversation to lock on to a position, but he didn't hear any sound until he crawled to the end of the passage.

"Are the people here dead?"

Feeling that something was not right, Lin Cheng lay at the end of the passage and frowned and thought carefully, it stands to reason that if this is really an underground shelter, according to his current hearing, even if he can't hear too clearly, as long as someone speaks, he should be able to hear some.

But no matter in the process of his descent or parallel advance, he didn't hear any sound at all, this strange situation made his heart more and more unremarkable, and he was worried that he would end up with nothing after tossing a big circle.
