Five-star mission?!

Qi Lin hesitated a little, the task difficulty scoring standard in "Wasteland Survival Rules" is not fixed, but a floating value, which will give the corresponding difficulty level according to the player's current strength.

Like the task of the mutated fathead fish in the Radiation Lake at the beginning, it was a four-star difficulty at that time, but if Qi Lin's current strength was to take it, most of them would only have one star left.

And this mission to infiltrate the central control room...... Although Super Mario's work is dirty and tiring, no matter how you look at it, it doesn't look like it can be worth a five-star difficulty.

With a five-star difficulty, the strength of the final mission objective is generally more than half that of the player who accepts the task, and even if there is no target such as a boss, the process of the mission must be extremely difficult and cumbersome.

"Is this pipe really just a ventilation pipe? And, Dr. Wang, why don't you go in by yourself and ask me, an outsider, to do so? ”

Qi Lin threw out two questions in a row, here he can't be cautious, when he disarms more than ninety percent of himself, in case he is trapped in this ventilation duct again, then the situation is a little bad.

“…… Ahem...... The ventilation ducts are clean...... But...... You need to break down the door of the pump room...... In the air pump room...... Still with one head closed...... Zombie ......" Wang Yuanhai seemed to hesitate, but still said the specific situation.

"Zombies? The kind that loses its mind? ”

"Right...... He was also one of the base's researchers...... Exposure to radiation...... It became...... Zombie...... It's not like me...... Memories and sanity have been lost...... I had to find a way to keep it in the pump room...... It's strong...... You should be able to ...... though. Help it get rid of it......" Wang Yunhai said a long paragraph in one breath, and then coughed violently, coughing for twenty or thirty seconds in a row, until some black-brown fragments similar to organ fragments were coughed out by it, and then he could breathe down.

Qi Lin didn't know what the zombie's respiratory system was, but it was obvious that the zombie doctor in front of him with the rank of colonel had a lot of problems with his lungs and respiratory tract.

From Wang Yunhai's words, Qi Lin could probably guess that the zombie was at least about E-level, otherwise Wang Yunhai would not have come to a "very strong" conclusion, and the difficulty of this infiltration mission would not be as high as five stars.

So, is the zombie in the air pump room the focus of this mission?

"But," Qi Lin said, "since you said it was strong, how did you keep it in the air pump room?" Moreover, how can I open the air pump room that even that zombie can shut down? ”

"For a few reasons...... 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 de-energized...... I can't open the door...... But...... On the soldiers outside...... There should be something with explosives or something......"

"Hmm...... Explosives? Qi Lin thought about it, and clicked "Accept Task" on the virtual dialog box that had appeared for a long time and could only be seen by him.

If it's just an E-class zombie, it's not a big problem, and in the case of a power outage on the eighth floor, even if this zombie doctor has any bad thoughts about himself, he can't manipulate the defenses on the eighth floor through the fire control room.

"Okay, then I'll go collect some explosives now, and besides, I need a detailed map of the eighth floor of the core tower and a diagram of the pipeline."

“…… No problem. As soon as Wang Yuanhai finished speaking, Qi Lin found that there were two more 3D stereoscopic maps on his miniature brain, which was exactly what he wanted.

“…… I didn't expect this to be able to play like this, but it's still in the game world......" muttered, Qi Lin said hello to Wang Yuanhai, turned around and left the fire control room.

There are many corpses of soldiers on the periphery of the core pillar tower, Qi Lin can easily find a lot of directional door breaking shells, this seemingly thin piece of stuff is filled with all highly concentrated C4 explosives, these things that are mainly composed of high purity (RDX) and TNT are not only powerful, but also due to the special charge structure, when exploding, it will only have an effect on the front, and will not accidentally injure the people behind it. Compared with the explosives bag that blew up the gate in the battle fort before, I don't know how many grades it is advanced......

Considering that the core pillar tower is a metal structure building, the directional door breaking bullets that are generally used to deal with masonry or concrete walls may still be lacking, Qi Lin collected more than a dozen directional door breaking bullets.

Judging from the situation on the floor of the fire control room, the thickness of the metal partition in the core column tower is about five centimeters, which cannot be compared with the metal partition at the entrance corridor.

With a metal partition of this thickness, it is no problem to block the bullets of those assault rifles, but in the face of anti-materiel weapons, it is a transparent hole for each shot.

As for the metal door of the air pump room, although the thickness is more than the partition, the inside is hollow, and there are various mechanical devices and the hydraulic system responsible for opening and closing.

Stuffing these directional door-breaking bullets into his backpack, Qi Lin found another roll of black tape to fix it, and then walked to the elevator of the core column.

Although the whole elevator room is running normally, because of the special design of the elevator, for the sake of defense function, the power supply line of the elevator exterior door on each floor is independent, and with the power failure of the eighth floor, the elevator exterior door of the eighth floor has become unable to open.

And if you use a directional door breaker directly from inside the elevator, it is likely to destroy the entire elevator. So Qi Lin had to stop the elevator to the seventh floor, then use a screwdriver to remove the ceiling of the elevator car, and then climb down the elevator shaft to the eighth floor.

This process is simple, but the actual operation is not small, and when Qi Lin finally climbed to the height of the eighth floor, he was a little helpless to find that the entire elevator shaft is an integrated structure, no matter which wall he chooses to blast, the entire elevator will be paralyzed.

“…… Luckily, I prepared Plan B......"

Using a metal hook on his belt to hang himself in the elevator shaft, Qi Lin took out a nuclear battery from his pocket, which was already an earthen battery slot, and then opened the cover of the electric box at the outer door of the elevator - since the door could not be opened due to a power failure, Qi Lin had to install a battery on the outer door......

After connecting several wires and plugging in the battery, Qi Lin released the hook, slid down into the elevator car with the steel cable, and then pressed the button on 8F.

The elevator quickly climbed to the eighth floor, and with a ding, the external door sensor that had been energized received the signal that the car stayed, and several indicators in the electric box instantly changed from red to green, and in a slight friction sound, the inner door and the outer door of the elevator slid to both sides at the same time.

"This is the eighth ......"

As soon as he stepped out of the elevator, Qi Lin felt something kicked under his feet, and at a glance, the ground on the eighth floor was also covered with the corpses of many intruders.

"At that time, the battle was fought to the eighth floor, no wonder the people of the 404 base destroyed the nuclear reactor in the base by themselves, and chose to end up together......"

The eighth floor of the power-off was dark, but it didn't have any impact on Qi Lin, and after glancing at the 3D three-dimensional map in his brain, Qi Lin quickly determined the location of the air pump room in the eighth floor.
