"Call it is called Kuway Information." Liu Cheng was incompetent in his name. This was the name Li Man had named him back then. It was confirmed that no one had registered.

Liu Yinuo took the notebook and communicated with Liu Cheng about the details of the company registration, nodded and said, "Then I will book a ticket and fly to Beijing tomorrow afternoon. We will try to get it done early so that you will not delay your business."

Liu Cheng nodded: "Well, if you have something to do, please contact me."

He opened his phone and Chen Wanruo sent a text message. There were only two simple words: Chengcheng...

Liu Cheng wanted to quickly reply to [Love], but after thinking about it, it was too cruel. After a while, she would figure it out herself.

When he stopped his hands flying on the keyboard, he opened the drawer and there was a photo inside. At the Lantern Festival in Baotuquan, there was a photo of two people standing in front of the porcelain tower.

I want to buy osmanthus and carry wine together, but it is not the same as a young man traveling.

This love story disguised as a young man finally returned to the original trajectory of the story.

Photos are just the broken shells of life and memory. Time has passed, and the melon seeds are swallowed one by one. After that, you can experience the taste. The photos left behind are just black and white melon seed shells all over the ground.

He put the photos deep in the drawer and continued to fly on the keyboard. The tool set has been open source and is available for all white hats, gray security vendors, and hackers.

He himself wants to write the main body of the web log analysis tool, which is the core program, and no one can replace him.

"Ding Dong."

"Ding Dong."

"Ding Dong."

"Sister!" Liu Cheng stopped the work in his hand and shouted, then he remembered that Liu Yinuo had already dragged his suitcase to the capital, registered a company, and his parents were in an educational institution and did not go home during the day.

He stood up and opened the door.

"Why are you here?" Liu Cheng looked at Li Man's appearance and asked in confusion.

He thought that he had already shown it very clearly last time, but this girl came to the door again.

Li Man's fox's eyes were full of smiles: "Your sister told me everything. You actually went to school to take graduation photos."

"You're a little free to do this." Liu Cheng made way open the door and let Li Man enter the house. His house was very crowded, and only his room was larger.

Li Man skillfully changed into slippers. Before she entered the door, she actually thought of many reasons, such as the excuses of your sister asking me to take care of you, but she is a person of Moji, and she likes it.

"I just took advantage of the situation. Could it be that I will come after you and Chen Wanruo reconcile?" Li Man asked an unanswerable question.

Liu Cheng bypassed the topic and said with a smile: "The remote control is under the TV, I'll do my job."

"Go, go." Li Man's hair was radiating and covered the blushing on her face. If she didn't really like it, how could she be so shameless and frivolous?

Liu Cheng brought his headphones, and they had already cooperated to record some videos, and the tacit understanding between the two recording videos was also increasing.

Shen Jiayi cleared her throat and asked softly: "Last time we talked about three handshakes and establishing a relationship. Today we will learn about four breakups, Master, what is four breakups."

Liu Cheng said absent-mindedly: "The client requests to disconnect and send fin. The server says that the message is received and will reply to ACK. At this time, the server also needs to disconnect and send fin to the client. The client restores the ACK, and the client and the server break up."

"We can see that fin has been sent twice in total, because the link to TCP is bidirectional, so please note here that ACK is uppercase and lowercase ack represents the number of the next packet."

"This sounds a bit complicated. We compare the client and server to the man and woman in love. The man: I'm fed up with you! Break up! Just send fin. The woman: Huh! Goodbye (ACK)! Break up (fin) after breaking up! The man: Goodbye ACK! "

"After breaking up, each of them will not delay each other, and the client and server will release the occupied resources."

Three handshakes and four breakups are the foundations of network communication, but even so, many people can't tell the difference between ACK and ack.

Shen Jiayi followed the script and nodded and said, "TCP is in duplex mode, so it needs to be closed in two directions. The closing of each direction requires request and confirmation, so there are only 4 times in total. The client sends fin and ACK once, and the server will also send fin and ACK once. Is that true?"

"Master, have you broken up?"

Shen Jiayi suddenly had a topic outside the script, and Liu Cheng was silent for a long time without answering it.

As Li Man and Liu Yinuo said, they have not yet requested or confirmed their breakup, and they have indeed occupied each other's resources.

If it were so easy to cut the relationship between two people, it would be as easy as disconnecting it.

Liu Cheng and Shen Jiayi recorded nearly an hour of video. This is a 20,000-hour course, from joining the company to becoming a regular, to programmers who independently perform established tasks at P5 level, and major courses in network communication and network security.

Of course, the charge is not a black-hearted 100,000 yuan, but 20,000 yuan, which is equivalent to 1 yuan per hour.

It can be said that it is quite cheap and will be paid in on-demand form.

Teaching Shen Jiayi alone is a lesson, recording a video to teach others is also a lesson, and Liu Cheng had no intention of refusing.

"What kind of person is Master in life?" Shen Jiayi asked murmured to herself while recording.

Liu Cheng smiled and said, "A very boring person."

He turned off the voice call, stood up, moved his body, and came to the living room. Li Man practiced the words she said when she was entering the room, and she was busy cooking in the kitchen.

Li Man's busy appearance at this time seemed to slowly overlap with the figure in later generations.

Every time Liu Cheng works overtime and comes home, no matter how late, Li Man will make a late-night snack for him in the kitchen. Every time Liu Cheng sees this scene, he will hold her waist that seems to be easily broken, and he is too lazy to take off her apron. It takes about two meals before the dining table stops screaming.

The waist essence is well deserved.

No matter how calm he is, he is a young man with a strong and energetic spirit.

"What are you doing?" Li Man asked softly and slowly. Liu Cheng came to her quietly and his hand had reached out.

Liu Cheng unbuttoned Li Man's apron and said with a smile: "You go watch TV, I'll cook."

"Oh, ah? You know how to cook. Your sister said that you only wash dishes since you were a child."

Li Man's shy neck was red. She was sure that if she hadn't spoken, Liu Cheng's hand would definitely not have reached towards the apron. She believed in her intuition and judgment.

When the breath of heat came, Li Man didn't want to refuse. If she hadn't been reserved, she wouldn't even want to interrupt Liu Cheng's movements.

What am I doing!

Li Man sat on the sofa, gasping for a while. This was not like her. She had been in love with XXX for two years and held hands no more than five times. She was resistant to her intimate behavior.

But those resistance emotions were as if they were not on guard in front of Liu Cheng.

She knew clearly where Liu Cheng's hand was about to reach out, but she was still hesitating whether to go down and remain silent, and to accept his actions.

Liu Cheng skillfully cut the vegetables, steamed them with rice, made one of the three fresh rice, one pot of meat, and made one of tomato and egg soup, two simple dishes and one soup.

"This pot of pork is so amazing!" Li Man tasted the pot of pork and stared at Liu Cheng with her eyes. She never expected that this boy was so good at cooking.

Liu Cheng washed his hands and said with a smile: "The thickening should be even, the oil temperature should be slightly higher, and the meat can float up after being put into the pot so that the meat will not stick together. It will be crispy on the outside and tender on the inside, and do not add shredded green onion and shredded ginger."

This is the pot bun made by Li Man. They have many memories, and their relationship has also fallen into the trouble of food, rice, oil and salt. They have had family problems. They have also quarreled over the garbage without taking it downstairs, and have had a quarrel overtime until very late.

When they couldn't separate, Li Man held back the anger in his heart every time and helped him deal with the women who came to him.

"You are so good at cooking." Li Man ate a whole bowl of rice and said embarrassedly: "Your sister asked me to take care of you, but now I have become a free meal."

Liu Cheng packed up the dishes and nodded and said, "It's okay, just rub it if you want to."

Li Man has achieved this and then pushing her out will not be cruel, it is sick.

"The partitions are all books bought by my dad. There are many novels. If you are tired of watching TV series, you can read books. There is a spare key for your home under the mat in front of the door. Next time you come, you don't have to knock on the door. Sometimes I'm working, and I won't hear it. I'll save you waiting outside for a long time." Liu Cheng said while washing dishes.

Li Man is a very intellectual woman. When Liu Cheng works overtime at home on weekends, she can hold a novel, a biography, or a very old classic. It seems that it will take a day to cry for a certain plot, and sometimes she laughs and leans back and forth.

"I can't reach it." Li Man stretched out his hand, and the book on the partition was a little taller.

Liu Cheng tied up his apron and asked, "Which book?"

"That's the book, "Gone with Gone." Li Man's voice gradually became lower and slower, and he was even a little embarrassed.
Chapter completed!
