Chapter 129: hard disk

　　 The falling elevator moved so loudly that the entire core column tower could feel violent vibrations. Although Wang Yuanhai didn't know that Wilde had been killed by himself, the time left for Qi Lin would never be much.
　　 Once Wang Yuanhai guessed that he might know something from Wilde, he might directly activate the defensive facilities in the core pillar tower to kill himself.
　　 Moreover, Wilde is dead, Qi Lin's value in Wang Yuanhai's eyes will naturally drop a lot...
　　 Qi Lin would not be surprised if Wang Yuanhai did something like crossing a river and demolishing a bridge.
　　 Judging from the current situation, the elevator shaft should be safe, and because of the power failure on the eighth floor, no matter whether it is surveillance or weapons, Wang Yuanhai cannot mobilize it. As for the central control room on the ninth floor
Qi Lin didn't know whether Wang Yuanhai showed him saved images or real-time monitoring. If it is the former, then for Wang Yuanhai, the central control room is also a blind spot of vision, and if it is the latter, it means that the central control room is in Under Wang Yuanhai's supervision, Qi Lin's actions must be more careful.
　　 At least, Wang Yuanhai could not see through his intentions before finding that hard disk.
　　 But there is one thing Qi Lin can be sure that even if Wang Yuanhai can see the monitoring of the central control room, he certainly has no right to mobilize the weapon facilities there, otherwise, he would not need to let himself restart the central control room system.
Along with the two 3D three-dimensional maps transmitted to Qi Lin’s personal brain, there is also a compressed file package. According to the task content, as long as Qi Lin restarts any computer in the central control room, the compressed file The package is directly copied into that computer through the infrared transmission interface, and his task is completed.
　　 "This should be some kind of computer virus, right?"
　　 The compressed file package with only a few hundred kilobytes, Qi Lin previously thought it was a backdoor key for the central control room system, but according to the current situation...it seems to be a virus more likely.
　　 Qi Lin’s personal brain is a binding item bestowed by the main brain. Although there is no fear of being infected by a virus, there is no way to parse this compressed file package.
　　In addition to providing information and storing data-related mission items, the personal brain cannot have any other impact on the game world.
　　 Qi Lin recalled all the things that happened after he entered the 404 base, and further confirmed his conjecture:
If Wang Yuanhai really has the system's backdoor key, can the central control room be opened. At least at the entrance hallway, he shouldn't watch him pass by death, otherwise, the next one to enter the 404 base People don’t know how to wait until the Year of the Monkey.
　　 In addition, the dying Wilde told himself not to trust Wang Yuanhai and found the computer hard disk in the central control room. What does that mean? Is it that Wang Yuanhai is actually a traitor to base 404? Or... has another meaning?

　　 Following the steel rails in the elevator shaft, Qi Lin once again returned to the eighth floor of the core tower. Although Qi Lin no longer trusted Wang Yuanhai, he still had to drill through the ventilation pipes of the air pump room to enter the central control room.
The central control room is the central hub of the entire core column tower and even the entire 404 base. The thickness of the metal gate is comparable to that of the central bank vault of the old era. Even if the power of the directional blast in Qi Lin's hand increases ten times, it is difficult to blow it up. open.
　　Recovered all the equipment and props that had just been scattered, Qi Lin picked up the Gauss sniper rifle with a scrapped barrel.
　　 Gaussian sniper rifle is different in caliber and shooting mechanism. Basically, the general barrel accessories can't be replaced. It seems that the only way to go back and find Passefani to re-order a barrel.
The original backpack was too worn out, but fortunately there were a lot of private soldiers' bodies on the ground. Qi Lin casually picked a pleasing tactical backpack, pulled it off and carried it on his body, and then picked up those corpses. The items and supplies that came back were put in.
　　 As for the weapons all over the floor, Qi Lin didn't have any thoughts. Anyway, the ventilation pipe was so narrow that even the backpack would have to be left in the air pump room, and no amount of weapons would be useful.

　　According to the pipeline structure diagram given by Wang Yuanhai, the No. 1 pipeline leads to the central control room. Qi Lin quickly found the air pump machine with a huge "1" on the far left of the air pump room.
　　 Putting the backpack, guns, etc. aside, Qi Lin walked to the air pump that was thick enough for two people to hug each other.
The vent pipe is divided into two parts. One part is a metal pipe buried in the wall of the building. The cut surface is a square with a length of 55 cm. The air pump connected to the outside of the wall is the black section in front of Qi Lin. Thick rubber tube.
There are dozens of fixing bolts at the joint between the rubber tube and the metal tube. Even if there are tools, it will take ten minutes to unscrew them all. Qi Lin simply summoned the bone blade and directly opened one on the rubber tube. A big enough hole, then bit a small dagger and got in through this hole.
　　The inside of the pipe is really clean. At least at this point, Wang Yuanhai didn’t lie to him, but every time he crawled ten meters in the pipe, Qi Lin had to stop and remove the metal filter that blocked the way before he could move on.
　　 After climbing a fifty-meter-long horizontal pipe, the pipe bends through an arc and leads straight to the central control room on the ninth floor above.
　　 Fortunately, the turning point of the pipe is an arc, not a 90-degree right angle, otherwise Qi Lin really can't get through.
　　 Hands and feet cling to the inner wall of the pipe in a toad-like manner, and the back pressed against it at the same time. Qi Lin maintained this posture and quickly climbed up the vertical pipe and quickly climbed to the top of the pipe.
Now, in front of Qi Lin, there is only the last obstacle left-that is a large blower fixed at the mouth of the duct~EbookFREE.me~ If you want to go out from this outlet, you can only use this one first. The blower is removed.
　　 The firearms that had been transformed for so many years, Qi Lin quickly used that small dagger to split it into original parts for a simple machine such as a blower, and then threw it down along the ventilation duct.
　　 The blower was removed, Qi Lin kicked open the last metal filter and entered the central control room of the core column tower.
　　 According to the image perspective of the central control room that he had seen in Wang Yuanhai's memory, Qi Lin raised his head and looked at a corner on the ceiling of the central control room. As expected, there was a surveillance camera there.
　　 It's just that the red indicator light that represents the working status is dimmed, that is to say, Wang Yuanhai can't actually monitor the situation in the central control room.
　　 Qi Lin breathed a sigh of relief, this way, it can be regarded as reducing him a lot of pressure.
　　 Out of insurance considerations, Qi Lin still threw the small dagger in his hand as a flying knife, destroying the surveillance camera lens, and then set his eyes on the machine in the central control room.
These machines are different from ordinary civilian computers in the old age. For the convenience of operation, all machines are connected to a large LAN server, and the data storage is a shared super hard disk, which is plugged into the wall. In a metal cabinet with two people on the side.
Thinking that he was about to know all the secrets of Base 404, Qi Lin couldn’t help but speed up a bit—but at this moment, a Rubik’s Cube projection made of red laser suddenly appeared in front of him. AI voice sounded again.
　　 "Please show your proof of authority, otherwise the system will activate self-defense facilities"
