Every evening, Lin Wancongee would stay at Xu Cheng's house and write homework in the bedroom with him for a while, until the two adults came back from work.

Now that she comes to Xu Cheng's house is as natural as returning to her own home, He Ying and Xu Jianghe like this lovely girl very much, not to mention that she also helps supervise her son's study, which is a hundred welcomes.

And Lin Wancongee also likes the atmosphere of Xu Cheng's house very much, and even deep down, there is a trace of envy for the relationship between Xu Cheng's parents.

"Did your mom and dad fight again yesterday?"

Xu Cheng took a sip of orange juice and looked at Lin Wan's porridge on the side.

During this time, Gao Manman and Lin Wancongee's father often quarreled, and the movement was very loud, and the entire family home knew about it, and there were rumors that the two planned to divorce.

Lin Wancongee stared at her workbook silently, wrote and calculated on the paper, and finally pointed out the question to Xu Cheng, "Xu Cheng, do you have an idea for this question?" ”

Xu Cheng leaned over to her, his face was about to stick together, and he could feel each other's breathing, but the two of them were used to it, and they only regarded it as an intimacy between friends, and they didn't have any special feelings.

He glanced at it briefly, "Chickens and rabbits are in the same cage, rabbits have four legs, and the small ones are just because... Chickens only have two legs, and if they can't figure it out, they can also do the equations..."

He wrote and drew on the calculus paper, and roughly listed the equations, "If there are X chickens, then there are 2X chicken feet exposed underneath... So you get it. ”

"I see." , Lin Wancongee nodded suddenly, "Actually, Xu Cheng, you are very smart, you can think of these problems, you always don't score in the exam, you must lose in carefulness..."

"Okay, okay, I'll be careful next time." , Xu Cheng casually perfunctory this topic, proposed, "I've been studying for so long, or let's watch cartoons." ”

Lin Wancongee glanced at Xu Cheng hesitantly, "What are you looking at?" ”

"Detective Conan, I just asked my dad to rent a set of Conan discs." In just a few years, the once invincible video hall of the Dragon Kingdom has almost closed down, but the model of renting discs has become popular, Xu Jianghe installed a home theater at home, and rented discs to play in his own home, which is very enjoyable.

By the way, this business model of renting films was learned from Lao Mei, where there is a company called Blockbuster that is mainly engaged in renting video tapes, which is a big giant enterprise in Lao Mei, and once a small company wanted to sell itself to it but was driven away, and then Blockbuster went bankrupt, and the small company called Netflix became a legend.

"Conan? No, I don't look at that. Lin Wancongee frowned and shook her head, "Every time I see that door click and close, I feel like I'm going to stop breathing, and I often have nightmares when I think about it at night." ”

"That's right." , Xu Cheng thoughtfully, "Since you're afraid..."

"Then it's even more up to it!"

Happy times are always short-lived, and after Lin Wancongee came home, Xu Cheng sat up from the sofa, stretched out, and started his formal work!

After a period of computer learning, Xu Cheng's own navigation website has long been developed by him, and has been in operation for two and a half years.

Xu Cheng named it "16 URL Navigation".

The technical content of URL navigation is not high, which is related to its function, after all, the meaning of the existence of URL navigation is to easily enter the URL to find the mode of the website, so 16 needs to do just to gather popular websites together, and establish links with them, so that when users go online, they do not need to memorize the URL at all, just one click.

At present, 16 has become famous in the Dragon Country, many Internet cafes are using this navigation site, Xu Cheng does things "very low-key", no one knows that he is the webmaster of 16, and his daily job is to check, update links, and then delete some illegal and viral links in time.

After finishing the work work, Xu Cheng decided to reward himself.

"Anyway, Mom and Dad haven't come back yet, you can take a sneak peek at that..."

He crept to lock the door, then lifted his mattress and pulled out a yellowed book from underneath.

This book was finally obtained by him, like a baby, hidden very tightly, and must not be seen by his parents, otherwise it will really be inexplicable.

"Boom."

Xu Cheng swallowed a mouthful of saliva nervously, opened the title page with a full face of spring, and turned to the place he saw last time.

"The solubility of a solid indicates that at a certain temperature, a solid substance..."

Chemistry for Grade 9

Xu Cheng is very strict with himself, in order to strive to make himself excellent in this life, the pace of life is very self-disciplined, and work and study are promoted simultaneously.

Especially in learning, he is particularly attentive, just because his academic performance in his previous life was average, and in this life he followed the principle of stupid birds flying first, even if the talent is not as good as others, I can always make up for it by starting to study a few years earlier.

At present, he has set himself the goal of-

Read books for four hours a day, and the culture is synchronized with junior high school students first!

At dinner, the family of three ate happily, and "The Granary of the World" was broadcast on TV.

Four years have passed, and the parents have not looked much older, but there is a scene of all things competing and vibrant, which is completely different from the original trajectory of the previous life.

Of course, this is inseparable from the butterfly effect brought about by Xu Cheng, a reborn person, who changed the fate of his family with a slight flap of his wings.

He Ying's current regional manager has done a very good job, and she has recently been promoted to deputy director of the marketing department.

On the other side of Xujianghe, Jing'an Communication has just taken a breather from the trough of the communications industry, and he holds the company's fingernail size shares, and he is currently mixed in the company's middle-level position, and also serves as a deputy manager in the marketing department.

The parents are working smoothly, the family is harmonious, and the Xu family has gone to the fast lane on the road to a well-off life, and the days are quite nourishing.

This is all something that Xu Cheng has really changed.

However, perhaps it is the world's self-healing mechanism that works, or perhaps the dust under Xu Cheng's era is too small, and in the past four short years, the main process of the world has not been affected by Xu Cheng.

Those bad things are still happening: the NASDAQ Internet bubble burst, the ascendant Internet is going to the darkest moment, and the communication industry is affected and ushers in the industry winter; The international situation is grim; Housing prices have skyrocketed; Milk Tea Lun was criticized for Jiang Lang's talent...

Good things are also going smoothly: joining the WTO, the return of the Hong Kong Olympics, the national football team rushing into the World Cup, breaking the ice in the Internet winter, and the 11 incident of Lao Meinai...

A few days later.

In class, the head teacher Zhu Ziqian pushed open the door of the classroom, followed by a little girl who looked dirty in clothes.

"Let me introduce to you, this is a new student in our class, transferred from Yingcai Primary School."

"Yu Yu..."
