After dealing with the affairs of the hospital, Zhang Shan rushed to the 444 building non-stop.

The sun has set, and the moon is getting brighter.

Zhang Shan squatted outside Building 444 for a while, and he found that every 3 minutes there would be a gap between the two patrol teams.

This is also his only chance to infiltrate the 444 Building.

Looking at the brightly lit 444 Building, Zhang Shan avoided the patrol and sneaked in through the side door.

As soon as he entered the building, Zhang Shan found that the lobby was full of people.

And these people can't be ordinary staff at all, but a group of people in black, scattered in groups of three or five in all corners.

Zhang Shan hid in the dim fire escape, looked at no one around, and continued to climb up the fire escape.

When he climbed to the eighth floor, Zhang Shan heard a series of footsteps coming up and down the stairs.

Zhang Shan looked at the corridor inside the fire escape, there was no one in the row, and then entered the garbage bin hiding in the corridor on the eighth floor.

That series of footsteps did not enter the eighth floor, but went straight down.

Zhang Shan listened to the footsteps that were getting farther and farther away, and his hanging heart suddenly relaxed.

Just as Zhang Shan was about to get up to leave, a patrol of ten people walked behind the dumpster.

Zhang Shan immediately lowered his head and was almost discovered, but fortunately there was a garbage bin blocking him.

It seems that this place cannot be left for long, and if a patrol comes from its front, it will be exposed.

Immediately, Zhang Shan retreated into the fire escape and continued to climb up the corridor.

He wanted to see where Ye Ziqin was being held.

It is said that the top floor of the 444 building is the chairman's office, and an arrogant person like Liu Qiming will definitely choose to do it on the top floor.

So Zhang Shan did not hesitate to climb the stairs lightly along the fire escape.

But as soon as he reached the tenth floor, he heard a rush of footsteps trotting in the corridor.

Helpless, Zhang Shan could only choose to enter the office space in the fire escape, looking for an opportunity to enter the office space.

Based on ten people per patrol, there are at least 200 people patrolling the building, not counting the black-clad people scattered around the corners.

Thinking of his opponents exceeding 200 people, Zhang Shan frowned unconsciously.

He wasn't afraid of too many opponents, he was worried that he would be entangled by these patrols and delay his time to rescue Ye Ziqin.

How could Liu Qiming let him go so easily, the three days given by Liu Qiming were just a cover in Zhang Shan's eyes.

If he wants to really rescue Ye Ziqin, I'm afraid it will be even more difficult, but he won't give up no matter what.

Zhang Shan gave up sneaking into the tenth floor and continued to climb up, he didn't believe it, in this 444 building, there was no loophole.

In less than a minute, Zhang Shan climbed to the seventeenth floor, but there was a sound of hurried footsteps from upstairs, and there was also a patrol in the corridor on the seventeenth floor.

At this time, Zhang Shan was like an ant on a hot pot, in a dilemma.

If you climb up, you will definitely meet the patrol head-on, but if you enter the seventeenth floor, you will definitely be spotted by the patrol.

It seems that you can only go down?

Finally climbed to the seventeenth floor, Zhang Shan was very unwilling, getting closer and closer to the top floor of the 444 Building, but he wanted to go down?

Just when Zhang Shan was at a loss, he was tapped on the shoulder.

Zhang Shan was speechless in surprise, when was there someone behind him? Why didn't he feel anything at all?

Zhang Shan turned around in disbelief and saw an old man in a security uniform standing behind him.

Before Zhang Shan could speak, the security guard made a "shhhh

The security guard looked at the back of the patrol team in the corridor on the seventeenth floor, and immediately transferred to a secret room next to him after pulling Zhang Shan into the seventeenth floor.

"You're the one they're going to arrest, aren't you? there's too many people here, come with me!"

The security guard turned on the flashlight in the secret room, found a small ordinary key in a bunch of keys, and neatly opened a cabinet in the secret room.

It turned out to be a narrow passage!

"You're security here?"

Zhang Shan looked hesitantly at the security guard who had already entered the passage.

"Yes, I've been working here for many years, I know everything here, come with me, it's bad if someone finds out!"

At this time, there was no way out, Zhang Shan could only follow the security guard into a narrow passage, but this passage could only be entered by one person, and the stairs were steep, so he had to grasp it with both hands and move slowly.

The security guard was below, Zhang Shan was above, and the two of them moved slowly downward.

Hearing footsteps on the left side of the wall, the two men immediately stopped moving, and when they couldn't hear the footsteps at all, they began to slowly climb down again.

After more than twenty minutes, the two finally went down to the first floor.

The security guard put his ear to the small door and listened for a long time, noticing that there was no movement outside.

After carefully pushing open the small door, I walked two steps to the security room.

Zhang Shan stretched out his head and looked out, there was indeed no one, two steps and one step, and quickly walked into the security room.

Zhang Shan squatted on the ground, looking out from time to time.

"Young man, I think you better give up, it's too difficult to get in!"

The security guard shook his head helplessly and said earnestly.

"It's not that I said, if you go in and are found, maybe they will slaughter you alive. ”

"Thank you for your kindness, but I have to go in!"

After speaking, Zhang Shan stood up and prepared to continue infiltrating the 444 Building.

Unfortunately, as soon as Zhang Shan stood up, there was a knock on the door behind him.

The security guard immediately motioned for Zhang Shan to squat down, and without hesitation, stood up to block Zhang Shan behind him.

The security guard immediately opened the door of the security room and saluted several black gas people, with smiles on their faces.

"Did you find anything unusual today?"

One of the men in black looked inside the security room from time to time.

"No, if there is, I'll report it to you as soon as possible!" said the security guard solemnly.

The man in black nodded, turned around and left with a few of his men, and walked towards the elevator.

The security guard wiped his forehead with his hand, and the sweat was scared out.

sat on the chair with a butt and looked at Zhang Shan who was squatting behind him, his eyes were full of complaints.

"You almost killed me!"

Seeing that Zhang Shan did not react, the security guard looked around again and said cautiously.

"Why do you want to help me? You and I don't know each other!" Zhang Shan asked puzzled.

"Because I used to be a soldier, I hate bad guys. ”

After the security guard finished speaking, he glanced at Zhang Shan again, "You still want to go up?"

"Of course!"

The security guard looked at Zhang Shan, shook his head, opened the drawer, and handed Zhang Shan a drawing.

"Since you have made up your mind, this is the structural diagram of the 444 Building, I can only help you so much, you hurry up and read it, and return it to me after reading!"

Zhang Shan took the drawing suspiciously, opened it and looked at it.

It turned out that the internal structure of the 444 building was not complicated, but there were too many patrols arranged inside, so that Zhang Shan did not have a chance to go in and explore.

Zhang Shan looked at this drawing carefully, and it clearly marked the fire escape, elevator, refuge floor, etc.

In less than a minute, Zhang Shan firmly remembered the whole picture in his mind.

The drawing was then returned to the security guard.

The security guard looked incredulous, this is considered to be finished?

The young man in front of him has such a good memory?

"Are you sure you remember? Don't look at it again?" the security guard looked at Zhang Shan curiously.

"I remember that this building has a total of sixteen elevators, two fire escapes, a refuge floor, two back doors in the lobby, a main entrance, a western restaurant on the second floor, an exhibition hall on the eighth floor, and a large conference room on the twentieth floor......"

Zhang Shan retold the structural diagram of the 444 building in his mind.

He memorized all the details in his mind, he didn't want to have any negligence, after all, a slight carelessness could become a fatal blow to himself or to Ye Ziqin.

"Yo, my memory is pretty good, but I want to remind you that the forty-fourth floor is the safest place in the whole building. "The security guard got straight to the point.

Zhang Shan nodded approvingly, because the 44th floor happened to be the refuge floor of the entire building.

"The Southeast Group is not easy to mess with! Are you sure you want to do this?"

Seeing that Zhang Shan didn't speak, the security guard spoke again.

Southeast Group?

Isn't this an ordinary security guard? How could he know about the Southeast Group?

"How do you know about the Southeast Group?"

Zhang Shan's eyes stared at the security guard, observing the details of the security guard, and seeing what flaws there were in the security guard.

"I heard about it when I came to work this morning, but in fact, our chairman didn't agree with the Southeast Group to come in and do these things. ”

"But the boss of the Southeast Group directly bought the company at a price ten times higher, who do you say would refuse! Now that I am a member of the Southeast Group......
