"It's drawn, this is the design and construction drawings of the T building!"

Three days later, Ma Wei handed some printed drawings to Li Zhen with dark circles under his eyes, not staying up late to do multi-person sports, but staying up late to get work.

This guy has been working hard for the past three days, and he has slept for less than ten hours in the three days, and the rest of the time he has been working, and finally drew the drawings.

After Li Zhen picked up the drawings and glanced at them, he directly excluded the above-ground buildings and looked for the underground buildings: "Do you know the underground buildings?" ”

"Underground? There are indeed basements, and here, these are the basement construction drawings! After finishing speaking, he found some drawings of the basement and handed them to Li Zhen.

The drawings are very complicated, Li Zhen frowned and looked at it for a while: "In addition to the entrance and exit of the elevator, is there any other entrance and exit in this basement?" ”

Ma Wei thought for a while and shook his head: "No, when we were building, there was only one entrance and exit, which was next to the elevator of the building, about ten meters underground. Ma Wei recalled for a moment, and finally shook his head.

"If you were going to build another entrance, which one would you choose?"

Hearing Li Zhen's words, Ma Wei fell into deep thought.

"Don't rush, think slowly!"

At this time, the third child pushed the door open in a hurry: "Big brother, the seventh is here!" ”

"So fast!"

As soon as the words fell, I saw a thin figure come out from behind the third child, and directly gave Li Zhen a hug: "Big brother, I'm here!" ”

"So fast? Monkey! ”

Lao Qi, nicknamed Monkey, this guy is very shrewd, and because he is not tall, he was often naughty when he was a child, so he was nicknamed Monkey again, and when he grew up, he went to the British Ark Force for a few years, and after he was discharged, he formed a mercenary group by himself, which has been active in Central Asia and Africa, and is also a small mercenary leader.

"I heard that my eldest brother was in trouble, so I rushed over immediately, brother, who is the target this time? How much can you earn! ”

Li Zhen directly pressed the monkey's brain: "Your kid is full of money, this time the target is a research institute, but this research institute has a relatively strict defense, it is a relatively difficult bone to gnaw, the last time dozens of people from the Revolutionary Guards took advantage of the darkness to attack, and finally returned in vain!" ”

Hearing Li Zhen's words, the monkey was a little more serious: "Dozens of people from the Revolutionary Guards haven't taken down a research institute?" Something! ”

"Okay, don't talk about this yet, you can rest for a while, just wait for my news!"

Hearing Li Zhen's words, Lao Qi smiled mysteriously: "Brother, I know that you are in big trouble this time, so this time I took out all my family resources and got two tanks, just outside Nell City, if you want to hit that research institute, I will directly let the tank bulldoze the building!" ”

Li Zhen glanced at this guy: "Okay, you, if you blow up the building, there are a hundred ways, go and rest first, see that your eyes are bloodshot, be careful of sudden death!" ”

Lao Qi didn't refute, and after hugging the rest of the brothers, he left the room and went to rest, and at this time, Ma Wei patted his head and suddenly thought of something, Li Zhen immediately looked over: "What did you think of?" ”

"I should have thought of it a long time ago!"

After finishing speaking, he found one of the basement drawings in the drawings, and then drew on it for a long time, and finally pointed to one of the places: "Here, a drainage channel was built here, and it was very large, and it was said that it was the building for sewage treatment at that time, but the city of Nell did not lay underground pipes at all, so even if it was to treat sewage, it should not be from such a deep place underground!" ”

Li Zhen quickly walked to the front of the drawing, confirmed the direction, and then opened a map of Nell, carefully referring to the range on the map: "You mean, there is an entrance and exit in this place?" ”

"Yes, if you want to build another entrance, this is the most suitable, here is reserved for a processing pipe, connected to the basement, if you want to build an entrance, you just need to dig all the way forward, and then dig a passage upward, if there is an exit, it must be here!"

After Li Zhen heard this, he quickly kept comparing on the map, and finally looked at Ma Wei: "If you build an entrance, how many meters of passage will there be?" ”

"It's hard to say, if it's just an ordinary entrance, it may be outside the wall of the building, if it is long, it's not a difficult thing, it may even go to hundreds of meters, thousands of meters, but the amount of work is very large, from the perspective of a professional construction engineer, the possibility is not high, because the amount of work is too large, there is no shield machine in Africa, if it is just by manpower to excavate, it will take several years or even longer!"

"And what if it's a few hundred meters?"

"How many hundred meters?"

"Yes!"

Ma Wei thought for a while, and finally shook his head: "If it is a few hundred meters, the amount of work required is not low, if it is only excavated by manpower, it may be difficult to exceed a hundred meters in tens of meters, this can be calculated by earthwork, one cubic meter is excavated from the ground and then transported out, it is very troublesome!" ”

After Li Zhen heard this, he nodded, looked at the map and fell into deep thought, not far in front of him was a residential area, with several streets in between. 、

"Can you draw a range?" After Li Zhen finished speaking, he looked at Ma Wei.

After thinking for a while, Ma Wei drew a circle on the map: "If you don't use machinery, you won't exceed this range, but generally speaking, the exit won't be very large, and if you want to find it, it's not easy!" ”

After Li Zhen heard this, he also agreed with Ma Wei's statement, and thought for a while: "I'm sorry for you, you have a good rest, if you need anything, I'll come to you again!" ”

Hearing Li Zhen's words, Ma Wei nodded, looked at Li Zhen and stopped talking.

"Anything else?"

"You said before that you would send me back to China, is it true?" Ma Wei now wants to return to China, although he is disabled, but life is more important than anything else.

"Yes, if you want to go back, when I'm done with things here, I'll arrange for you to go back, rest assured, it's very safe!"

Hearing Li Zhen's words, Ma Wei's eyes finally burst out: "Okay!" Let me know when you can go! ”

"Think about it, is there any other way out of this basement!"
