The number of people in this laboratory is so small that it is beyond Zhang Yang's expectations, and the personnel of the entire building should not have been warned yet, Zhang Yang They took the elevator to the 7th floor and the other party did not move, under Zhang Yang's command, the four people almost found Yun Wei and their location at the shortest distance.

The three guards were not together, only one was guarding the hallway, and the other two were resting in the opposite room. Zhang Yang's position was in a T-shaped corridor, and the enemy was on that vertical top, with No. 9 and No. 10 blocking Zhang Yang behind them, and No. 11 on the opposite side.

Seeing that No. 9 kept gesturing, when the third finger was stretched out, No. 11 pounced, and the automatic rifle with a silencer in the air opened fire directly. "Poof" and "poof" two dull sounds sounded, and the people in the corridor planted directly, and the distance between them was not far, about four or five meters.

Before the enemy could fall to the ground, No. 11 had already pounced on the enemy's corpse, while No. 9 and No. 10 were directly guarding the door of the room where there were two other enemies. Zhang Yang ran over quickly, turned on the computer and looked at it, the light spots in the room did not move, and he obviously did not wake up.

No. 9 and No. 10 made a few gestures, Zhang Yang didn't know what they meant, but when No. 10 took a grenade from his waist, Zhang Yang didn't have to think about it to understand what it meant. Obviously, the 9th just meant to kill them directly, but the 10th disagreed, for fear of a sneak attack by the people inside, judging from the cross-sectional map, this room is not big, and it is estimated that it is more than ten square meters.

An anti-infantry grenade goes in, and you don't have to think about it to know what the result is. Gently opening the door, No. 10 pulled the safety bolt of the grenade directly and threw it through the crack in the door. Zhang Yang hurriedly squatted down against the wall, covering his ears with his hands.

A dull sound of "boom" sounded, the power of the grenade was not as great as Zhang Yang thought, and even the door was not blown open, but there were a few "poof" and "poof" sounds from the door, which should be the sound of the grenade's fragments embedded in the door panel. After the grenade exploded, the 9th and 10th quickly opened the door and rushed in, and soon two dull gunshots were heard inside, and then the 9th and 10th opened the door and walked out.

Zhang Yang walked over from a distance, and when he came to the door, Zhang Yang was shocked to find that the person who died in the corridor was different from the person below, and was a white man. Having solved all the dangers, the 11th quickly opened the door of the room where Yun Wei was being held and rushed in.

"How's the 7th and 8th?" There was soon an exclamation from inside, Zhang Yang also hurriedly rushed in, and when he entered the house, Zhang Yang's pupils shrank sharply, Yun Wei and another instructor were hung on the roof, but at this moment, both of them had been put on the ground, and the bodies of the two people were covered with blood, especially the left leg of the other instructor had been twisted into an incredible angle, and it was obvious that the leg had been broken.

"I didn't ...... It's okay...... A few of you have finally died, and you won't come back...... I have to collect Lao Tzu's body and see how it is on the 8th. Yun Wei gasped and grinned, with blood foaming on the corners of his mouth, but said with a smile.

After finishing speaking, Yun Wei saw Zhang Yang who came in, and after seeing Zhang Yang, Yun Wei couldn't help but smile bitterly: "I said, isn't it?" Zhao Tou also brought his students here? That's how you guys got in? ”

"That's right, this kid is pretty good." No. 9 quickly commented, and then turned on the headphones and said: "No. 1, the threat above has been successfully cleared, No. 7 and No. 8 are still alive, except for some skin injuries, the two of them have no problems." ”

Zhang Yang felt a little numb in his scalp, and the leg of Instructor No. 8 almost became 90 degrees in the other direction, or was it a skin injury?

"No. 10 and No. 11 stayed, managed to move the two of them out, and then drove outside to pick us up, and No. 9 brought No. 13 over, we're in a bit of trouble here." Zhao Fei's voice sounded directly in his ears.

"Instructor, are you alright?" During the report on the 9th, Zhang Yang leaned over and asked.

"It's okay, I can't die, I didn't expect this to be seen by your kid." Yun Wei smiled and said indifferently.

"On the 13th, let's go, we need our help below. The two of them are fine, they can't die, we have encountered this kind of injury a lot. No. 9 walked over, patted Zhang Yang's shoulder and said, although his tone was flat, but Zhang Yang's gaze unconsciously changed, at least they had not seen an ordinary person who could remain so calm when he saw these scenes.

Nodding, Zhang Yang followed No. 9 and quickly ran to the basement. After entering the elevator, Zhang Yang turned on the computer and took a look, there was no surveillance video on the 7th floor of the basement, and Zhang Yang didn't know what was inside. However, judging from the current position of Zhao Fei and them, the enemies along the way have obviously been killed, and the remaining enemies should be below the 7th floor underground, and a special method should be used on the 7th floor of the basement, and the life detector has no effect, so I don't know how many people are in it.

Although it is impossible to confirm the identities of these people at present, thinking about Zhao Fei's identities, Zhang Yang knows that the media will not know about this matter even in the end, at least Zhang Yang has never heard of these things in his previous life. Watching the elevator go down endlessly, Zhang Yang's mind couldn't help but start recalling, and suddenly Zhang Yang remembered an event that seemed to be related to this matter.

Zhang Yang doesn't remember the specific time, but it seems that in his previous life, around this time, in this direction on the outskirts of H City, the report at that time was that a violent natural gas explosion occurred in a 12-storey civilian building, resulting in the destruction of the entire building's foundation and being burned by fire, because the news in his memory was six years ago, Zhang Yang remembered not clearly, how many people died in the report at that time, but it was definitely not a small number.

But at this moment, Zhang Yang suddenly found that if he remembered correctly, I am afraid that the building in his memory and the building where he is now are very likely to be one, you know, although this is also under H City, but the surrounding is only the closest town to H City, H City has not developed here in recent years, in the location of such a town, although the 12-story building is not abrupt, but it is absolutely rare.

Gas explosions? Before Zhang Yang could get in touch with anything in his head, the elevator opened with a "ding dong", and when he came out of the elevator, Zhang Yang immediately saw Zhao Fei and them guarding an automatic door.

"All the personnel have been cleared, and the main passage is this, but this gate requires a pass and a password, and we don't have it." Zhao Fei saw Zhang Yang coming, and pointed to the automatic steel door.

Zhang Yang walked up quickly and began to check, but the results of the inspection made Zhang Yang a little depressed, and he quickly looked left and right, there were no dead people nearby, it was estimated that Zhao Fei hid the corpse. "Didn't you find the keycard on the people around here?"

"Yes, but it doesn't work anymore, when we started it just now, they found out, this door was closed from the inside, is it possible to crack it?" Zhao Fei said.

Zhang Yang didn't answer, but quickly took over the door card in Zhao Fei's hand, and then directly took out the pistol on his body, and then smashed the automatic steel door password disk next to the butt of the gun, and pulled out a few wires inside, saying that these password disks are still a kind of computer system, and the two data cables inside were pulled out and plugged directly into his notebook, I have to say that military notebooks are powerful, it is obvious that this kind of notebook has taken into account similar functions, and there is no interface on these civilian notebooks at all, It's all there.

After entering the decoding system, Zhang Yang quickly calculated, and then raised his head and said: "No, the system in this is not any kind of system on the market at all, and its encryption method is also specially written, it is not impossible to crack it, but time does not allow, even if there are huge computer resources, it is impossible to unlock this encryption system in a few hours." ”

Zhao Fei's brows immediately furrowed, and after a pause, Zhao Fei said, "Don't wait, prepare to blast!" Break the wall directly, the people have already been rescued anyway, and as for the information inside, if they don't decrypt it, they can't be sent at all, so our task is to completely destroy the bottom. Number 4 is ready to blast! ”

Zhao Fei's words came over, and several people quickly took out square pieces of explosives from their bodies, and when they saw these explosives, Zhang Yang couldn't help but smile bitterly, is it because of these bombs that the news from the previous life appeared? But it should be unlikely, after all, directional blasting cannot cause so much damage, how many bombs are needed to blow up the entire building, it is estimated that Zhao Fei and their last life broke through, and they blew up the instruments and materials below.

Looking at No. 4, they have nothing to do there and start to install explosives, since they are ready to blast directly, then the explosion door is not interesting, although I don't know how thick this steel door is, but as long as there is a thickness of more than 20 centimeters, the TNT explosives needed are probably not a small amount.

But what they want to break through is underneath, just blow up the ceiling or the wall, these things are reinforced concrete, as long as the explosion point is set, it is much easier to blow up the wall than to blow up the steel door. Obviously, No. 4 is Zhao Fei's professional blaster, Zhang Yang is idle, and he simply began to check the encryption program of this steel door again.

After trying to detect it for a while, Zhang Yang felt that this encryption program was a little familiar, as if he had seen it somewhere. Frowning and thinking about it carefully, Zhang Yang's mind suddenly lit up, and he suddenly remembered an encryption software he had made from that perverted version about ten days ago.

At that time, Zhang Yang analyzed the encryption rules and methods of the encryption software in detail, which was very similar to the software in front of him. The current program is not quite the same as the simple encryption method of increasing the key length used by banks and other financial systems, this encryption program pays more attention to its own rules, and if its encryption rules are cracked, then it is very easy to crack this thing.

But the kind of banking and financial system is different, as high as 128 or 256 digits of the key, even if you know the rules, the time it takes to forcibly crack it is an astronomical amount.
