"It seems like it's really ......"

Hearing Lin Cheng's analysis, Lin Yongjian couldn't help frowning, "And we don't know anything about the situation inside, so we don't know how strong their defense is......"

Speaking of this, Lin Yongjian's eyes suddenly rolled, and after getting up and walking back and forth in this room, he returned to Lin Cheng's side and said in a low voice: "I just remembered, since we have determined that the staff of this research institute is indeed hidden under this research institute, then there is no need for us to break through from the main entrance!" ”

"Oh?"

Hearing Lin Yongjian's words, Lin Cheng couldn't help but raise his eyebrows, "What do you say?" ”

"That's right!"

Seeing Lin Cheng motioning for himself to continue, Lin Yongjian hurriedly put away the excitement on his face and said as if offering a treasure: "No matter what they have done before, there is one thing that these people can never change, that is, as long as they are human, they need to breathe!" And given the size of the institute above ground, I don't think the underground shelter would be too small, so they would need to build enough vents and wide enough to circulate the air! As long as we find one of the vents, we should be able to sneak in without noticing! ”

"Hmm......"

After listening to Lin Yongjian's analysis, Lin Cheng pondered carefully for a moment with his chin, and then asked, "But in this way, there are two questions in front of us. First, since it is an underground shelter, it must have been built according to how to hide and how to build it at the beginning, and we don't have enough manpower, so searching for a ventilation duct in this area is like looking for a needle in a haystack! Second, even if we are lucky enough to find the ventilation duct, the height and width of the duct are unknown, and if the ventilation duct can't even get into the Coke, what is the use of finding it? ”

"I've thought about all of this just now."

But Lin Yongjian smiled and waved his hand, and said confidently: "Let's not care if this pipe can accommodate a single person to pass through, just talk about the location of this ventilation pipe, I think I am still confident that I can find it!" Because I have already observed the surrounding situation on the way here, the location of this institute is between four streets, and it is a typical 'lonely building'! If you want to build underground space in such a building, there is no other way than to dig vertically downwards! Because if we dig horizontally, it is easy to dig up the surrounding sewer pipes, so if we want to find a vent, we don't need to cross the street at all, we just need to continue to search the first floor of this building~"

As Lin Yongjian methodically analyzed one by one, Lin Cheng's eyes became more and more strange when he looked at him, and after he finished speaking, he finally couldn't help but ask, "That...... You wait! If I'm not mistaken, you should be studying computer science on your student ID card, right? But how do you ......? ”

"Hey......

Seeing Lin Cheng looking at him with a strange expression, Lin Yongjian couldn't help but smile and explained: "That's the case, although I studied computer science in college, my father is actually engaged in engineering, and I will go out to work with him as long as I have a holiday, and I have an understanding of this aspect after a long time......

"Okay."

Hearing Lin Yongjian's explanation, Lin Cheng nodded, and couldn't help but think in his heart that since he came to Yanjing this time, this Lin Yongjian should have dug up the biggest wealth by himself!
