Chen Jian went out in the afternoon and prepared everything. He took the high-speed train to Yanjing in the evening.

When Lin Dazhuang arrived in Binjiang, he told himself that he had written down everything in a notebook and asked Chen Jian to go to get it again. Chen Jian could understand it completely.

After all, Lin Zixiang died last night and could not appear again.

Although Lin Dazhuang cracked and mastered the webcam in the company, it was only limited to the company.

In this environment full of cameras, if Lin Dazhuang appears in the company that night and takes away the notebook, it will be difficult to ensure that he will not be recorded by other surveillance cameras.

After arriving in Binjiang, Lin Dazhuang was completely safe, and then he would not appear in any surveillance screen in Yanjing. This is the safest and safest way.

Chen Jian did two things in the afternoon, one was to buy a new mobile phone card, and the traffic card was activated, and the other was to prepare a ecstasy incense again, which was a large package.

The newly-appointed traffic card is placed in Lin Dazhuang's mobile phone, which can monitor the situation in Lin Dazhuang's company in real time.

In Lin Dazhuang's company, Sun Meng and his group were always there, even when they ordered takeout when they were eating. It is conceivable that they were going to be stationed here.

Before coming to Yanjing, Lin Dazhuang had already informed Chen Jian that there was a fire passage behind the office building where his company was located, and all surveillance could be avoided by going through the fire passage.

Although this fire passage will be locked at night, it is not difficult for Chen Jian to open the lock of the fire passage, flashed into the office building, and went up the tenth floor along the fire passage. Lin Dazhuang's company is located at the tenth floor of this office building.

Upon reaching the tenth floor, Chen Jian flashed into the public bathroom on the tenth floor. Stepping on the board used as a partition for large pits, Chen Jian gently opened the cover of the air duct.

The air duct was not big, about forty centimeters square. Chen Jian took a deep breath, shrank his shoulders, and got up.

Although the air duct is small, the air duct is spacious. Chen Jian followed the air duct and found the right direction and crawled towards Lin Dazhuang's company.

Sun Meng and his group were already full of wine and were gambling around a table in the company.

Chen Jian slowly climbed to a distance of several meters away from them and stopped. Because the wind vent was at the stop where Chen Jian stopped, Sun Meng and his friends played cards, there was no wind vent.

Chen Jian opened Lin Dazhuang's mobile phone and could clearly see the every move of Sun Meng and his group. At this time, Sun Meng and his group were pushing Paijiu, and a group of people were gathering there. Sun Meng was on the banker and the others bet.

Chen Jian pinched his nose and lit the ecstasy incense at the entrance of the wind duct.

After the colorless and tasteless ecstasy was ignited, it drifted into the company along the vent of the wind duct.

"Why do I feel like my eyelids are a little too open?" Sun Meng rubbed his eyes, and before he could finish his words, he fell to the ground.

The others also fell one after another like Sun Meng.

Chen Jian saw this scene through the surveillance screen, smiled, found the right direction, and crawled towards Lin Dazhuang's office along the wind channel.

The air duct in this building is made of composite fiberglass board. After Chen Jian climbed to Lin Dazhuang's office, he opened an opening on the air duct. He leaned out and immediately saw the brown cowhide notebook in the corner. The opening position of Chen Jian was only more than one meter away from the brown cowhide notebook. Chen Jian poked out half of his body, reached out to get the notebook, and then reset the air duct that broke the opening, and then returned the same way.

Getting off the air outlet in the bathroom, Chen Jian pushed up the cover of the air outlet, went downstairs along the fire passage again, took a taxi at the intersection, headed straight to the train station, and returned to Binjiang with one ticket.

When Chen Jian came back, it was not yet dawn.

Knowing what Chen Jian was doing, neither Jiang Ge Ge nor Lin Dazhuang slept and had been waiting for Chen Jian.

"So fast?" Lin Dazhuang asked, "Have you got it?"

"Get it." Chen Jian took out the brown cowhide notebook and shook it, then threw the phone back to Lin Dazhuang, and asked with a smile: "Is that right?"

"Yes." Lin Dazhuang said, immediately turned on his phone and said, "I'll delete the surveillance camera."

"No!" Chen Jian reached out to stop Lin Dazhuang.

"What?" Lin Dazhuang asked suspiciously.

Chen Jian smiled and said, "You can watch the replay. I got the notebook in your office that I entered more than two hours ago!"

Lin Dazhuang was a little confused, but as Chen Jian said, he found the video of that period and watched the replay.

After watching the entire replay video, there is nothing abnormal except for the inexplicable fall of Sun Meng and his group!

Prince Jiang kept watching this video, and looked at Chen Jian in confusion, saying, "It's really confusing to see it!"

Chen Jian smiled and said, "If the air duct on the ceiling was not broken, there would be some movement if it weren't for breaking the air duct wall, and there wouldn't be even a need to get lost!"

This is also the reason why Chen Jian prepared the ecstasy incense. In the middle of the night, a little movement will be particularly clear. It is above the ceiling and will be easily discovered.

If you are confused by Sun Meng and the others, you don’t have to worry at all.

"Although you cracked the surveillance, once you delete these surveillance, Wu Changbin will be suspicious." Chen Jian said: "Although I can't do it perfectly, even if this group of people wake up, they will definitely have no clues. They just think they are asleep."

The ecstasy thing depends on the amount. If it is small, even if a person falls asleep, he will remember the situation before he falls asleep. If the weight is heavy, it will make people unable to remember the things before he falls asleep, and just think that he is asleep.

It is obvious that Chen Jian did this for the sake of security.

This safety is of course for Lin Dazhuang's sister.

Lin Dazhuang naturally understood this and couldn't help but look at Chen Jian with a grateful look.

Chen Jian smiled and said, "Okay, I'll study this notebook and see what to do!"

After saying this, Chen Jian turned around and lying on the bed. Chen Jian opened the brown cowhide notebook, a thick cowhide notebook, which was almost used, and there were only a few blank pages left.
