After leaving the dormitory and facing the afterglow of the sunset, Li Hua smiled and was very satisfied with the improvement effect of the sub-skill-function this time.

In the past, those difficult-to-understand function questions are now easy to do, without any effort. Solving the questions is like deciphering game levels, which is very interesting and very satisfying.

I actually got addicted to solving math problems.

If it were before, Li Hua would never believe that this would happen to him.

"Yang Kai, that boy betrayed the 'revolutionary friendship' and once again destroyed the collective unity of the dormitory. Should we find a way to tease him and make anger?" Zhang Haitao locked the dormitory door and suddenly suggested hatefully.

"What if I get angry? What can I do? It's better to find a partner myself." Lin Zhikun said lightly, not interested in Zhang Haitao's proposal.

"Do you think I don't want it! It's not that easy to have money but no money, but no beauty!" Zhang Haitao thought for a while and said discouragedly.

"Who said that a partner who has no money and no beauty can be found? As long as it is sexy enough!" Li Hua laughed and retorted.

After saying that, Li Hua followed Lin Zhikun's footsteps and walked towards the stairs.

"Why don't you just say that you don't practice fake moves, why don't you be slutty?" Zhang Haitao caught up with Li Hua's footsteps and said unconvincedly.

"I don't need this trick. I just don't want to hit you." Li Hua smiled and couldn't help but remember the junior girl who was catching up with him in the library a few days ago.

"Tsk, who can't speak loudly!" Zhang Haitao rolled his eyes.

"Haitao, you have to recognize the reality! Old Li needs to be tall, have a figure, and look OK. He is still a 'storm' in the school. It's much easier for him to find a partner than us." Lin Zhikun coughed twice and woke Zhang Haitao up.

"Damn it! Forget it, I won't talk anymore, otherwise I won't be able to eat later." Zhang Haitao was speechless and admitted his mercy.

The three of them talked and laughed and came to the cafeteria.

At meal time, the team for making meals had already arrived at the entrance of the cafeteria. The three of them joined the team and slowly rang forward.

The queue is long and the speed is very slow, and the waiting time is boring.

Lin Zhikun and Zhang Haitao picked up their phone and started to swipe it. Li Hua hesitated whether to take advantage of this time to add another skill point.

After several points added, Li Hua noticed some characteristics of the skill system when instilling skill experience.

Perhaps, the reason why the sub-skills are related to each other under the big skills is that when the first sub-skill is upgraded, the amount of data will be higher and it will take more time to digest it. Then, when the subsequent sub-skills are added, the state will be much easier.

It is better to act than to move.

Li Hua narrowed his eyes slightly, and the sub-skill tree of mathematics immediately appeared in his mind, and then he used a skill point in the sub-skill of mathematics - derivative.

"Ding, you used a skill point for the derivative, and the derivative is upgraded to intermediate level, and you will obtain skill attributes: data derivation, skill effect: derivation ability increases by 19%, and derivation efficiency increases by 21%.

Li Hua had already been ready to take over, narrowed his eyes slightly, silently endured the erosion of data flow, and knowledge of various derivatives continued to emerge in his mind.

Derivatives are also called derivative function values, also known as micro-business, which are important basic concepts in calculus. Derivatives are the local properties of functions. The derivatives of a function at a certain point describe the rate of change of this function near this point. There is an extremely close relationship between mathematical sub-skills-derivatives and sub-skills-functions.

As expected, the negative impact of the data flow on the body this time was much weaker, and Li Hua felt that his condition was much better than last time.

About seven or eight minutes passed, Li Hua recovered from the state of upgrading his skills.

Next, just click another sub-skill - points to get the course of advanced mathematics. A hint of joy flashed across Li Hua's face and he was very happy.

"Old Li, what's the silly smile! It's your turn." Zhang Haitao handed Li Hua a stainless steel rice plate and reminded him.

Li Hua suddenly realized and quickly took the plate and cooked the dishes.

Soon, the three of them found an empty table, gathered together to have dinner and chat.

At this moment, a girl accidentally discovered something, and walked straight towards them with a rice plate.

"What a coincidence for Senior Li Hua! I met this seat here, someone was sitting there!" The girl walked to the empty seat opposite Li Hua and asked happily.

"Ah! No one, please sit down!" Li Hua saw the person clearly. It was Zhou Qianqian, the junior girl who had been chatting with him in the library before, and said quickly.

"Yes!" Zhou Qianqian quickly put down the rice bowl, as if she was afraid that someone would steal the seat.

Today, Zhou Qianqian was wearing a short red and black skirt and a white short-sleeved T-shirt. Her originally small and delicate body highlighted a more obvious charming curve. She was paired with a pure baby face, which was both cute and beautiful.

Zhang Haitao, who was sitting next to him, suddenly looked straight.

"Li Hua, who is this?" Lin Zhikun's eyes lit up and he looked at Zhou Qianqian.

"Her name is Zhou Qianqian, a freshman. By the way, I don't know which department you are from." Li Hua introduced Zhou Qianqian and asked embarrassedly.

"Hmph, Senior Li Hua, I sent you a WeChat message, and you didn't reply!" Zhou Qianqian snorted lightly and asked angrily.

Upon hearing this, Li Hua was slightly stunned and suddenly remembered that Zhou Qianqian had sent him a cartoon picture. At that time, he was busy designing the entries and ignored this meaningless message.

Li Hua smiled bitterly and quickly explained: "Sorry, I have seen your information, but I have been busy working on entries recently and have forgotten to return it."

"Oh! That's it! Then forgive you! I'm from the English Department." After hearing Li Hua's explanation, Zhou Qianxi's face cleared a little, and then asked curiously: "Senior, what competition do you want to participate in? Aren't you participating in the ball game?"

"No, I participated in the computer design competition. Next, I may not have any football competitions to disappoint you." Li Hua apologized.

"Computer Design Competition! It looks very high-end! The works you designed should be very interesting!" Zhou Qianqian looked at Li Hua with big eyes and asked with interest.

"It's a bit technical. There are quite a lot of people participating in the competition. My work has not been done yet!" Li Hua smiled awkwardly and replied.

"So! When will the competition start? Can I visit it? Senior, what entries have you designed?" Zhou Qianqian transformed into a little fan and asked questions one after another.

"I don't know the specific process! It's my first time participating,..." A hint of embarrassment flashed across Li Hua's face, and he gritted his teeth and answered it patiently one by one.

The two of them asked and answered each other, looking very unhappy.

Zhang Haitao wanted to interrupt several times, but he had no choice but to insert it. He also wanted to remind Li Hua that he had not introduced them to Zhou Qianqian yet!
