Liu Jiajun did not plan to wait until the evening to go, because after his previous observation, there were more guards in that building, and it was a 24-hour shift.

Liu Jiajun copied the information of the guard Sebastian's badge, and it was the best time to enter the building when he rested in the afternoon. If you wait until the evening to act, it is impossible for Sebastian to go back to continue his duty, so that as long as two Sebastian badges appear in the access control system at the same time, Liu Jiajun will be exposed immediately.

And there is another disadvantage after dark, Liu Jiajun is a killer, he knows the psychology of various security personnel very well, and the vigilance of these people at night will be several times that of the day. Therefore, only by playing a time difference can Liu Jiajun maximize the safety of his operation.

The building he was going to infiltrate was the Houston Research Institute's Data Center Building, which sits in the northeast corner of the Institute, separated from the Buffalo River by a park. Because of the Buffalo River as a barrier, the zombies in this park were cleared by the soldiers a few months ago, and they were enclosed in the area of the institute through the outer wall as a place for everyone to rest and move.

Liu Jiajun once again came to the place where he had squatted, and the building of the data center had appeared in front of him. The tall building has a modern façade, with mirrored walls with patterns that resemble circuit boards, and elevators flanked by elevators that resemble the appearance of blade servers.

There was no longer a figure to be seen outside the building, so Liu Jiajun adjusted his state and walked towards the building. When he was about to approach the entrance of the building, he suddenly covered his stomach with his right hand, and his face showed a rather uncomfortable look.

The guards in the building noticed Liu Jiajun who was suddenly approaching, and several of them left their posts and walked towards Liu Jiajun. The guard came to the door and stopped Liu Jiajun, who was going to come in.

"I'm sorry, sir, outsiders are not allowed here," the guard held out his hand to stop Liu Jiajun.

"I'm sorry, I need ...... urgently right now I urgently need a toilet, maybe I had a bad stomach at noon, and now it's in a mood with me," Liu Jiajun's acting skills are very good, not only his expression is very realistic, but even sweat on his forehead.

Several guards looked at his face and began to hesitate, "You can't just let people in here. ”

"I'm really about to take it anymore," Liu Jiajun's body bent down, his right hand pressing his stomach stiffly, "If it weren't for the fact that there happened to be a building here, I might have to solve it under the tree outside." Please understand, I think you must have encountered such a situation in a daily manner. ”

"Okay, come with me, the toilet is there," a guard rubbed his forehead and had to take Liu Jiajun to the bathroom next to the hall. After Liu Jiajun entered, he returned to his post just now, but his eyes glanced in the direction of the bathroom from time to time to see when Liu Jiajun would come out.

Entering the bathroom, seeing that no one followed up, Liu Jiajun's face immediately regained calm, he looked at the situation on the ceiling, and found the location of the vent.

Liu Jiajun came to the lower compartment of the vent, from where he planned to climb up and enter through the vent. After the door to the cubicle was locked, he lowered the lid of the toilet, stepped on the lid himself, and used his hands to pry open the board of the vent above the ceiling.

After taking off the board, Mr. Lau left his shoes next to the toilet bowl and placed a pronunciation device on the toilet lid. He had prepared a stomach-wrenching moan in the gadget, and played it before he was ready to climb into the vent.

After preparing the things in the compartment, Liu Jiajun climbed into the pipe above the ceiling with the board of the vent, and after all his body was drilled in, he put the board back in its original position, so that the ceiling above the compartment was restored to its original position, and there was no trace of being touched at all.

Along the ventilation duct, Liu Jiajun quickly crawled forward, his crawling posture was strange, his palms and toes did not touch the inner wall of the pipe, but relied on the elbows and knees separated by clothing to quickly and lightly contact the area under him.

Liu Jiajun didn't have much time to complete the operation, he came in to borrow the toilet in disguise as if he had a stomachache, and if he stayed inside for too long, the guards outside would definitely be suspicious.

The conditions were tough, but he was confident, a confidence based on experience. Liu Jiajun has been to many buildings in his career as a killer, and he only needs to see the exterior of some buildings to know its function, and he can basically judge the floor structure inside. When he entered the data center this time, he had secretly observed the hall, and as he crawled through the ventilation ducts, the route of the pipes also made him a little more sure.

Mr. Liu's first target was to go to the power room, where he planned to destroy the entire building's power supply so that it would be paralyzed for a short period of time, so that the building's surveillance cameras would not work. Once he has done that, he can drive all the way to the floor where the database is located.

Sebastian's badge information will help Liu Jiajun pass through the various access controls inside the building, in Liu Jiajun's judgment, the power supply of this access control system is most likely to be supplied and guaranteed by backup power generation equipment, so he will not worry about the access control system will also be paralyzed after destroying the power equipment in the power supply room.

Of course, if the building's access control system was not supported by backup power generation equipment, Liu Jiajun would immediately abandon the operation and return to the previous bathroom in the shortest possible time.

Everything was as expected, Liu Jiajun found the power supply room through the ventilation duct very smoothly, he came to the door, and did not find anyone on duty inside. Of course, this is also expected by Liu Jiajun, because in a stable and mature work system, this place does not need to be on duty around the clock.

All switchgear in the power supply room is on a wall, and on the wall is a workbench with various instruments.

Liu Jiajun came to the side of those switchgear, and he brought an electromagnetic interference device with him, which Yuan Fang also prepared for him before leaving. The size of the jamming device is very small, and the appearance is made to look like a lighter, and it also has the function of ignition.

Liu Jiajun pressed on it, and then he heard a "z" sound from the switches on the wall, and then some red and blue sparks popped out of it.

The meters in the power supply room dimmed for a moment, and Liu Jiajun put away the lighter-shaped interference equipment and quickly left the power supply room.

The lights in the hall suddenly went out, and the screens of several computers that were working went black. The guards next to him all showed surprised looks on their faces, everyone, look at me, I look at you, I don't know what happened.

"What's going on, is it a power outage?" A man in charge of the guards frowned, and he picked up the communicator on the table, ready to contact someone from the logistics department to come and have a look.

"Damn, what do those guys do in operation and maintenance do to eat, doesn't the circuit system require them to come and check it often," the companion next to him thought that the power in the building was interrupted due to the aging circuit, and he couldn't help but complain.

"Let's go inside the bathroom," the person in charge of the guard did not rush to dial the phone of the logistics department, but shouted to a companion, motioning for him to see if Liu Jiajun was in the toilet.

The person in charge suddenly thought that there was an outsider like Liu Jiajun in the building, and coincidentally, a few minutes after the outsider came in to borrow the toilet, there was a problem with the power system in the building.

Another guard walked towards the bathroom at the behest of the person in charge, and when he came to the door, he just pushed the door open when he heard Liu Jiajun's groaning from a stomachache inside, and the guard's eyes also saw his shoes through the gap under the cubicle.

"Man, there's a power outage, you better hurry up." The guard shouted inside, then closed the door and returned to the hall.

The person in charge looked at him, with an inquiring look in his eyes, and the guard nodded, signaling that Liu Jiajun was still in the toilet.

Only then did the person in charge relax and dial the phone number of the logistics department and inform them to send someone to check the line.

There are not many people in the building, and after knowing that the cameras have lost their function, Liu Jiajun has a lot less worries about his actions, and he quickly searches between floors based on experience and intuition, and after a while, the location of the database is really found by him.

Hold the watch close to the location of the access card identification area on the device, let the device read out the identity information of Sebastian that he copied, and when the door opened, Liu Jiajun dodged and got in.

He looked at his watch, 6 minutes had passed, and looking at the rows of black cabinets inside, Liu Jiajun finally breathed a sigh of relief.

The figure shuttled rapidly between the cabinets, Liu Jiajun's gaze quickly swept over the dozens of large cabinets, and finally confirmed that there were several servers inside that should be used by the institute to store important information.

Without time to hesitate, Liu Jiajun chose one of the cabinets, he opened the cabinet door, took out a portable storage hard drive he was carrying, and pulled out a cable from it to connect it to the server in the cabinet. The light on the hard drive is on, and the green light is increasing from left to right, indicating that the data is being copied in.

"Hurry up, hurry up," Liu Jiajun didn't expect the amount of data to be a bit large, and a few minutes passed in this meeting.

"It's too late," Liu Jiajun has been keeping an eye on the time, and judging the amount of remaining data according to the green light on the hard disk to copy the amount of data, he knows that he can't completely copy the data in this server today, in order to ensure the safety of the operation and not to startle the snake, he decisively gave up the plan to continue copying.

Pulling the cable back and putting it into the mobile hard drive, Liu Jiajun put away the equipment, and restored the door of the black cabinet to its original state, and then he left here quickly, and the soles of his feet kept walking towards the place where he returned to the vent.

The people from the logistics department were on their way to arrive, and the head of the guard in the hall looked at his watch again, and his face showed impatience.

"Go and rush that guy, he's been in the toilet for too long."

The guard who had gone to the toilet to check on Liu Jiajun's condition walked over there again, and he pushed the door open, this time going to the cubicle to knock on the door there.

When the door opened, the guard saw Liu Jiajun's figure appear next to the sink.

Liu Jiajun was washing his hands under the faucet, and when he saw the guard pushing the door in, he asked him with a puzzled face, "What's wrong with the electric light here, it suddenly dimmed just now." ”
