Duan Yun sat in Chen Jia's office for a while, and after smoking the cigarette in his hand, he left the company and prepared to go home.

Tang Yan has ended her short-term vacation since yesterday, and from today, she will go to the head office for a period of training.

In fact, generally speaking, stars from professional classes basically do not need to receive training, but for stars like Tang Yan who make their debut by singer drafts, they need to undergo some further study, and Star Pictures will hire some teachers from film and television academies every year to train some potential new actors in the company, including some acting theories and professional knowledge in film and television, which is undoubtedly a good opportunity for Tang Yan.

It's just that there are very few places for this kind of training, and only newcomers who the company thinks have potential will have the opportunity to participate, and it can also be seen that Star Pictures attaches great importance to her.

Wang Ke's affairs don't seem to affect her for the time being, and Taishan has always been responsible for picking her up, so Duan Yun doesn't have to worry about Tang Yan's safety for the time being.

Tang Yan was not there, and Duan Yun's life in Kyoto became simple and plain.

After finding a roadside stall on the street and having breakfast, Duan Yun walked straight back to his apartment.

It's just that what Duan Yun didn't notice was that at the same time, a white Ford sedan was always slowly following Duan Yun.

It wasn't until Duan Yun entered his neighborhood that the Ford stopped.

The driver of the car was a tall man with an angular face like a knife, and a dragon-shaped tattoo was faintly visible on his half-open chest, with five claws flexed, which was extremely hideous.

The next moment, the tattooed man took out his mobile phone from his pocket, dialed a number, and spit out the gum in his mouth.

"Erlong, what's the matter?" a deep middle-aged man's voice came from the other end of the phone.

"Brother Bo, I'm now downstairs in the apartment where Duan Yun lives, didn't Wang Gongzi already buy this kid's two legs at a high price, so that he would never be able to play football?

"Can you do it alone, Wang Gongzi said that this kid has kung fu, and the strength of his fists is very strong, and ordinary people can't bear it. The middle-aged man on the other end of the phone was obviously a little worried, so he continued: "In addition, it is easy to be exposed during the day, or you wait, and I will find you a few more helpers at night......"

"No need!" A flash of disdain flashed on the tattooed man's face when he heard this, only to hear him continue: "That kid is a football player, he knows how to fart, I can do it in a few minutes by myself, why bother pulling a few points of bonus?"

"Hehe, Erlong, I know that your kid is good at kung fu, but if you miss this matter, I'm afraid of startling the snake, after all, this kid is also a celebrity in the sports circle......"

"Brother Bo, you don't need to say any more, just give me the money and get it ready!" said the tattooed man with some impatience.

"Okay, I wish you success! As long as you do a good job, I will immediately transfer the money to your account!"

After Bo Ge on the other end of the phone finished speaking, he hung up the phone directly.

After the tattooed man put the phone back in his pocket, he took out a large bag from the passenger seat and pulled out a lump of clothes from it.

The tattooed man wore this outfit that looked like work clothes on his body, and the logo of 'Jiajiale Cleaning Company' was prominently printed on his chest.

Then he put on a blue work cap in the style of a baseball cap, took a fake mustache from his pocket, pasted it, and shone it on the car window before pushing the door and getting out of the car.

The next moment, he lit a cigarette, took a puff, and strode towards Duan Yun's apartment with a huge tool bag.

At the same time, after returning to the apartment, Duan Yun sat in his study and took out the password disc information that Professor Guo Haitao had given him before.

In his spare time, Duan Yun would often check the materials and programs in the research CD.

Different from the code text that Guo Haitao brought him before, Duan Yun found that one of the discs contained a half-finished encryption program, according to Guo Haitao's previous statement, he needed Duan Yun to find the vulnerability of this encryption program and give suggestions for improvement.

Although it is said that this is only a half-finished encryption program, Duan Yun found through this research that the degree of encryption of this password is much higher than the password he has cracked before, and the level is indeed only seen in Duan Yun's life.

Preliminary analysis, Duan Yun found that this encryption program used two different sets of irreversible algorithms, even though Guo Haitao had told Duan Yun part of the program code in the CD, Duan Yun still failed to successfully crack this password program.

The most important thing is that this encryption method is extremely complicated, and during this time, the program written by Duan Yun is getting bigger and bigger, and the number of codes to crack the program has reached nearly 20,000 lines!

Not to mention whether this program can really be cracked successfully, just such a large amount of work is enough for Duan Yun to spend a considerable amount of time and energy.

However, Duan Yun's long-term research has indeed yielded some results, and he has a hunch that he is getting closer and closer to finding the flaw in Guo Haitao's password.

Just when Duan Yun was engrossed in writing a program in his study, the tattooed man just now had already taken the elevator to the floor where Duan Yun was.

Duan Yun's apartment building is located in a unit with only two households on the first floor, but Duan Yun has never seen who his neighbor lives in.

The tattooed man first knocked on Duan Yun's neighbor's door, he obviously only knew the floor where Duan Yun's residence was located, but he hadn't yet determined which house Duan Yun was.

"Knock knock!

After knocking on the door a few times in succession, there was no sound inside, and the tattooed man walked to Duan Yun's door.

"Knock knock!"

"Who!" Duan Yun in the room asked loudly after hearing a knock on the door.

"Ah, I'm from the cleaning company, and I need to carry out routine pipeline cleaning and maintenance for the residents of this community, please open the door. After hearing that it was Duan Yun's voice coming from the room, the tattooed man's eyes lit up and he said in a loud voice.

Immediately after, he quickly opened the blue tool kit printed with the cleaning company in his hand, and took out a thick pipe wrench from it!

As long as Duan Yun opens the door, the tattooed man will rush in as soon as possible, even if he is a person with kung fu, if he is firmly hit by this pipe wrench, it will be either death or injury!

This trick tattooed man has used it several times, it is clean and neat, and he has never missed, in his opinion, Duan Yun will definitely be hit this time!

"Wait a minute......" Duan Yun in the room was busy finishing the last line of code of the program, so he shouted casually.
