Chapter 100: Searching

"It's done. This is the design and construction blueprint for the t building!"
Three days later, with black circles under his eyes, Ma Wei handed over some printed drawings to Li Zhen. He didn't stay up late for group activities, but stayed up late to finish the work.
This guy has been working hard for the past three days, sleeping less than ten hours in total, and working the rest of the time. Finally, he has drawn the blueprint.
After taking a glance at the blueprint, Li Zhen immediately excluded the above-ground buildings and searched for the underground ones: "Do you know about the underground buildings?"
"Underground? There is indeed a basement here, and these are the blueprints for its construction!" After speaking, he pulled out some blueprints for the basement and handed them to Li Zhen.
The blueprints were very complicated, and Li Zhen frowned as he looked at them for a while. "Besides the elevator entrance, are there any other entrances or exits for this basement?"
Mas pondered for a second and shook his head: "No, when we were building it, there was only one entrance and exit, which was next to the elevator in the building, probably about 10 meters underground. It took us quite a while to dig the hole!" After a brief recollection, Mas shook his head again.
"If you had to build another entrance, which location would you choose?"
Upon hearing Li Zhen's words, Ma Wei fell into contemplation.
"Don't hurry, take your time!"
At this moment, Third Brother pushed open the door excitedly and exclaimed, "Big Brother, Seventh Brother is here!"
"So fast!"
As soon as he finished speaking, a slim figure emerged from behind Third Brother and gave Li Zhen a hug. "Big Brother, I'm here!"
"You came so fast? Monkey!"
Lao Qi, also known as Monkey, is a very shrewd guy. He was nicknamed Monkey because he was not tall when he was a child and often mischievous. After growing up, he joined the British Noah's Ark Corps and stayed there for a few years. After retiring, he formed his own mercenary group, which has been active in Central Asia and Africa. He can be considered as a mercenary leader that is neither big nor small.
"I heard that my big brother was in trouble, so I rushed over immediately. Brother, who is our target this time? How much can we make?"
Li Zhen pressed down on the Monkey's brain and said, "All you think about is money. This time, our target is a research institute, but their defense is quite tight. It's a difficult nut to crack. Last time, dozens of members of the Revolution Guard snuck in at night and returned without success!"
Upon hearing Li Zhen's words, the monkey became a bit serious: "The Revolutionary Guards couldn't even take down one research institute with dozens of people? That's disappointing!"
"Alright, let's not talk about this for now. Just rest and wait for my message," said the speaker.
Upon hearing Li Zhen's words, Lao Qi smiled mysteriously and said, "Brother, I know you've run into big trouble this time, so I've pulled out all the stops. I've brought in two tanks, stationed just outside of Ne'er City. If you need to take down that research institute, I'll have the tanks level the building."
Li Zhen glanced at this guy in disdain: "Alright, if you really want to blow up the building, there are a hundred ways to do it. Go take a rest, your eyes are all bloodshot, be careful of sudden death!"
老七也没有反驳，和其余几个兄弟抱了一下之后，离开房间就去休息，而这个时候，马伟拍了一下脑袋突然想到了什么一样，李震立刻看过去：“你想到了什么？”
"I should have thought of it earlier!"
After speaking, he found one of the blueprints of the basement, and then drew on it for a while. Finally, he pointed to a certain place and said: "Here, a drain was once installed. It was made quite big, and at that time, it was supposed to be for sewage treatment in the building. However, in the city of Neel, there are no underground pipes, so even if there is a need for sewage treatment, it should not be from such a deep underground location!"
Li Zhen quickly walked to the front of the blueprint, checked the orientation, and then opened a map from Neil, carefully referring to the range on the map: "So you mean there is an entrance and exit at this location?"
"Yes, if we were to build another entrance or exit, this would be the most suitable place. There is a reserved pipeline here that connects to the basement. To construct an entrance or exit, we just need to keep digging forward and then excavate a passageway upwards. If there were to be another exit, this would definitely be the spot!"
After hearing this, Li Zhen quickly gestured repeatedly on the map and then looked at Ma Wei, "If we build an entrance, how long of a tunnel do you think we'll need?"
"It's hard to say for sure. If it's just a regular entrance, it's probably located outside the walls of the building. If they want to build a longer one, it's not impossible, with a length of a few hundred or even a few thousand meters. However, the construction process for a project of that size is quite extensive. From my perspective as a professional architectural engineer, it's not very likely to happen because the project would require a huge amount of work. There are no tunnel boring machines in Africa, and if they rely solely on manual excavation, it could take several years or even longer!"
"Then what if it's several hundred meters?"
"Several hundred meters?"
"Yes!"
Ma Wei pondered for a moment before shaking his head, "If it's several hundred meters, the amount of work required will be quite substantial. If we rely solely on manual excavation, it may be difficult to exceed one hundred meters in just a few dozen meters. This can be calculated using earthworks. It's very troublesome to excavate one cubic meter from underground and then transport it out!"
After hearing this, Li Zhen nodded and fell into deep thought while looking at the map. Ahead of them was a residential area with several streets in between.
"Can you mark out a range?" Li Zhen asked and turned to Ma Wei.
Ma Wei thought for a while and drew a circle on the map: "Without using machinery, it won't extend beyond this area, and in general, the exit won't be very big. If you want to find it, it won't be easy!"
After hearing this, Li Zhen also agreed with Ma Wei's statement and thought for a while: "Thank you, you need to rest well. If there is anything I need, I will come find you!"
Hearing Li Zhen's words, Ma Wei nodded and looked at Li Zhen as if he had something to say.
"Anything else?"
"You mentioned before that you would send me back to China, is that true?" Ma Wei is feeling a bit homesick now, even though he is disabled, being alive is more important than anything else.
“Okay, if you want to go back, I will arrange for you to go back after I finish my business here. Don't worry, it's completely safe!”
Hearing Li Zhen's words, Ma Wei's eyes finally lit up with excitement: "Great! Let me know when I can leave!"
"Think carefully, is there any other exit out of this basement!"
