My hi-tech Library

His first profit was 2 million, and the next 2 million was not far.

Li Yi did not know how to spend so much money at once.

Last night, he had treated his roommates to a midnight snack. He had spent more than a thousand yuan and rented two sets of cloud servers. He had spent more than three thousand yuan and bought a few sets of clothes online, two pairs of sneakers, a new phone, and a high-end notebook. In total, he had spent less than forty thousand yuan.

Buy a car? Buy a house?

Li Yi did not need these things for the time being.

He did not know how to drive a car and had to take the driver's license test. There was no need for him to buy a house. After graduation, he might not stay in Yang City. Moreover, it was still difficult for him to buy a bigger house in Yang City with this money.

With so much money still in his card, Li Yi transferred 500,000 yuan to his father's card and transferred 2,000 yuan to his sister, Li Wenxiu, on WeChat.

Just as the money was transferred, Li Wenxiu immediately video-called him.

Li Yi smiled and accepted the video call. A palm-sized beautiful face appeared on the phone screen. Her eyebrows were somewhat similar to Li Yi's and she had delicate features.

"Brother, where did you get the money? Did Dad give it to you?" Li Wenxiu asked curiously.

"No, I earned it myself," Li Yi explained with a smile.

"You earned it? How much did you earn? Why are you so generous?" Li Wenxiu was shocked and asked endlessly.

"Just take it and spend it. Why are you asking so many questions?! If there's nothing else, I'm hanging up!" Li Yi said indifferently and was about to hang up.

"Brother, wait! My phone screen is broken. I want to change my phone. Give me more!" Li Wenxiu begged pitifully.

"Why would you change the entire phone when only the screen is broken?" Li Yi frowned.

"I've been using my phone for two years and it's very slow. I might as well buy a new one!" Li Wenxiu pouted and retorted.

"Alright! I'll transfer some more to you. Don't spend it all at once!" Li Yi closed the video and transferred another sum of money.

Soon, Li Wenxiu received 3,000 yuan.

Li Wenxiu's small mouth opened slightly in surprise.

She did not expect her usually stingy brother to suddenly become so generous. He had transferred a total of 5,000 yuan to her.

Li Wenxiu was extremely happy and curious.

"Thank you, Brother. How much did you earn?! C'mon! Tell me!" Li Wenxiu could not help but ask curiously.

"No, thank you." Li Yi refused decisively. If she knew that he had earned 2 million, it would definitely be endless.

"…" Li Wenxiu sent a series of ellipses.

Li Yi smiled and ignored him. He closed WeChat and called his father, Li Yanshun.

The call was quickly picked up. Li Yanshun asked with a trembling voice, "Little Yi, I just received 500,000 yuan in my bank card. Did you transfer it? Where did you get so much money?"

"That's right. I transferred it. I earned it from writing the code for a software. In the future, you and Mom don't have to work so hard. I have the ability to earn money now." Li Yi smiled and replied.

"Are you serious? You can earn so much money from writing code?" Li Yanshun was pleasantly surprised and asked inquisitively.

"Really, I can earn even more in the future!" Li Yi said confidently.

With the endless alien books in the "library", Li Yi believed that as long as he worked hard, his future would definitely become better and better. How much money he could earn in the future was only secondary. Only by inventing the library's alien technology and changing the world could he lead the technological trend. Only by living like this would there be meaning in life.

"Alright, alright, you haven't graduated yet, right? Will it delay your studies?!" Hearing this, Li Yanshun was pleasantly surprised and asked with concern.

"No! My studies are good! It won't delay my studies at all." Li Yi smiled and consoled.

"That's good, that's good. I'll keep this money for you when you get married," Li Yanshun said happily.

"No need. Take the money and spend it. You can buy a house or a car. If there's not enough, I have more!" Li Yi hurriedly advised.

"Alright, alright. With this money, why don't we rebuild our old house?" Li Yanshun suggested.

"Alright, alright. Arrange it as you see fit. Let me know if it's not enough." Li Yi agreed readily.

The loophole detection tool was basically a "gold mine excavator". If his family needed it, he could just let it continue digging for more "gold". It was not a problem for him to satisfy his father's small wish.

"Alright, I'll discuss it with your mother. Bye!" Li Yanshun said happily.

After hanging up, Li Yi was filled with joy. He was very happy to satisfy his family with his own ability.

After the call, Li Yi returned to the dormitory from the corridor.

Zhang Haitao, Lin Hang, and the others were all at the computer table, busy with programming experiments.

Li Yi also sat in front of the computer table and hurriedly did the programming experiment.

Sleeping in class was not a matter. The key was to hand in the homework. Usually, the homework might be related to the final exam and might become one of the contents of the final test.

Li Yi was confident in getting good results for all the subjects in the test next month.

Being called a "sleeping god" by his classmates in the class did not have any negative effects on him. Li Yi did not take it to heart. In university, self-study ability was what mattered. As long as one passed the exam and obtained enough credits, it was not a problem for them to successfully graduate.

With a series of keyboard typing, Li Yi finished the programming homework the computer teacher had left behind in less than a few minutes.

The test results of the codes were fine as usual. In an instant, Li Yi copied the code into a document, modified the name, and sent it to the homework group chat.

Seeing that Li Yi had finished the experiment homework so quickly, Zhang Haitao, who was sitting in front of the computer, revealed a constipated face.

"Old Li, are you done? I really can't find the bug in this program. Please help me." Zhang Haitao looked at Li Yi and asked for help helplessly.

"I don't want to go down tonight, help me bring some food back," Li Yi requested.

"No problem! My treat." Zhang Haitao agreed without hesitation. He held his notebook and walked to Li Yi eagerly.

Li Yi looked at Zhang Haitao's laptop screen and tested the operation state of the next code. He saw the problem at a glance.

Li Yi pointed at a certain code and reminded, "This bug is because the operator has to be overloaded. If you overload it, you have to use the member function. The Friend function is actually equivalent to a function that's not a class, so you can't use your own this… You used it wrongly here."

"So that's the reason. I understand, I understand!"

Zhang Haitao left with his notebook with a regretful expression. He blamed himself for being too careless.

Li Yi smiled and opened the loophole scanning tool to continue digging for more loopholes.

To be honest, it was quite satisfying for him to earn money this way once or twice. However, after doing it for a long time, Li Yi felt that it was too much of a waste of time. There was countless precious knowledge in the "library" waiting for him to learn. It was not worth it to waste time digging loopholes.

He had to think of a solution. Suddenly, he realized that if he could leave this matter to others, he would have more time.

Li Yi pondered this seriously and the more he thought about it, the more tempted he became.
