Chapter 125: Layer 8

　　 Five-star mission? !
　　 Qi Lin hesitated a bit. The scoring standard of the task difficulty in the "Rules of Wasteland Survival" is not fixed, but a floating value, which will give the corresponding difficulty level according to the player's current strength.
　　 Like the mutated fathead mission in Radiation Lake, it was four-star difficulty at that time, but if Qi Lin's current strength were to pick it up, there would probably be only one star left.
　　 And this task of sneaking into the central control room...Although Super Mario's work is dirty and tiring, it is not as difficult as it can be worth five-star.
　　 Five-star difficulty. Generally, the final task target strength is more than half the strength of the player who accepts the task. Even if there is no target such as BOSS, the task process must be extremely difficult and cumbersome.
　　 "Is this pipe really just a vent pipe? And, Dr. Wang, why don't you go in by yourself, but ask me, an outsider?"
　　 Qi Lin raised two questions in a row. Here he must be cautious. When disarming more than 90% of his own arms, if he gets stuck in this ventilation duct again, the situation will be a bit bad.
"...Cough...the ventilation pipe is clean...but...you need to break the door of the air pump room...in the air pump room...with one end closed...zombies..." Wang Yuanhai seemed to hesitate. However, the specific situation was explained.
　　 "Zombie? The irrational one?"
"Yes... he was also one of the researchers at the base... was exposed to radiation... became... a zombie... different from me... memory and sanity have all been lost... I can only find a way to lock it in In the air pump room...it is very strong...but you should be able to...help it get rid of..." Wang Yunhai said a lot of words in one breath, then coughed violently, and coughed for 20 to 30 seconds until After some dark brown fragments similar to organ fragments were coughed up by it, it was able to ease the breath.
　　 Qi Lin didn't know what the zombie's respiratory system was like, but it was obvious that the lungs and respiratory tract of the zombie doctor with the rank of colonel in front of him were not small.
From Wang Yunhai’s words, Qi Lin can probably guess that that zombie is at least about E-level, otherwise Wang Yunhai would not come to a "very strong" conclusion, and the difficulty of this infiltration mission would not be. Up to five stars.
　　 So, is the zombie in the air pump room the focus of this task?
"However," Qi Lin said, "Since you said it is very strong, how did you close it in the air pump room? And, how can I open the air pump room that can be closed by a zombie? "
"For some considerations... the door of the air pump room... there are two start switches... one in the central control room... one in this fire control room... but... now the eighth floor where the air pump room is located has been cut off. ...I can't open the door...but...the soldiers outside...should have something with explosives..."
　　 "Hmm...explosives?" Qi Lin thought for a while, or clicked "Accept task" on the virtual dialog box that had been there for a long time and only he could see.
If it's just an E-class zombie, the problem is not big. Moreover, even if the zombie doctor has any bad thoughts about him when the power is cut off on the eighth floor, it cannot control the eighth floor through the fire control room. Defense facilities.
　　 "Okay, I'm going to collect some explosives now. In addition, I need a detailed map of the eighth floor of the core column and pipeline structure."
　　 "...no problem." As soon as Wang Yuanhai finished speaking, Qi Lin found that his miniature brain had two more 3D maps, which was exactly what he wanted.
　　 "...I didn't expect this to be able to play like this, it's still in the game world..." After muttering, Qi Lin and Wang Yuanhai said hello, turned and left the fire control room.
There are many soldiers’ corpses on the periphery of the core column. Qi Lin can easily find a lot of targeted bombs. This seemingly thin piece of stuff is filled with highly concentrated C4 explosives, and these main components are high. Purity (RDX) and TNT are not only powerful, but because of the special charge structure, they will only have an effect on the front when blasting, and will not accidentally hurt the people behind them. I don’t know how much advanced it is compared to the explosive bag that used to blow up the gates in the Fortress...
　　Considering that the core column tower is a metal structure, the directional blasting power generally used to deal with masonry or concrete walls may still be lacking. Qi Lin collected a dozen pieces of directional blasting.
　　 Judging from the situation on the fire control room floor, the thickness of the metal partition in the core column tower is about five centimeters thick, which is completely incomparable with the metal partition at the entrance corridor.
　　The thickness of the metal partition is no problem to block the bullets of the assault rifle, but in front of the anti-material weapon, it is a shot with a transparent hole.
　　 As for the metal door of the air pump room, although the thickness is greater than that of the partition, it is hollow inside, and there are various mechanical devices and the hydraulic system responsible for opening and closing. The total front and back is probably less than five centimeters.
　　 stuffed these directional breaking bullets into the backpack, Qi Lin found another roll of black tape to fix it, and then walked to the elevator of the core tower.
Although the entire elevator room is operating normally, due to the special design of the elevator, the power supply lines for the outer doors of the elevator on each floor are independent for the purpose of defense function. With the power failure of the eighth floor, The outer door of the elevator also became unable to open.
　　 And if the directional breaking bullet is used directly from the inside of the elevator, it is very likely that the entire elevator will be destroyed. Therefore, Qi Lin must stop the elevator to the seventh floor ~EbookFREE.me~ and then use a screwdriver to remove the ceiling of the elevator car, and then climb the elevator shaft to the eighth floor.
The process is simple to talk about, but the actual operation is not that difficult. When Qi Lin finally climbed to the height of the eighth floor, he found reluctantly that the entire elevator shaft was an integrated structure, no matter which side he chose to blast. The walls of the building will paralyze the entire elevator.
　　 "...Fortunately, plan B is prepared..."
Hanging himself in the elevator shaft with a metal hook on his belt, Qi Lin took out a nuclear battery from his pocket, which had an earthen battery slot, and then opened the electric box cover at the outer door of the elevator Since the door cannot be opened due to a power failure, Qi Lin had to install a battery on the outer door...
　　 After connecting several wires, he plugged in the battery. Qi Lin released the hook, held the steel cable and slid into the elevator car, and then pressed the 8F button.
The elevator quickly climbed to the eighth floor with a ding sound. The external door sensor that had been powered on received the signal to stop the car, and several indicator lights in the electric box instantly changed from red to green. In the sound of friction, the inner door and outer door of the elevator slid to both sides at the same time.
　　 "This is the eighth floor..."
　　As soon as he got out of the elevator, Qi Lin felt something kicked under his feet. At first glance, the ground of the eighth floor was also covered with the bodies of many intruders.
　　 "At that time, the battle had reached the eighth floor, no wonder the people at base 404 would destroy the nuclear reactors in the base and all their choices..."
　　The eighth floor of the power failure was dark, but it had no effect on Qi Lin. After a glance at the 3D map in the brain, Qi Lin quickly determined the location of the air pump room on the eighth floor.
