"Host, you can't blame me for this, I'm thinking about you comprehensively, otherwise you will be a small single dog in a few years, and this system will definitely not do anything to pit the host, so you are safe." "The system is humanized and coquettish.

"Damn, big brother system, why did your voice become like this, you are angry, I have goosebumps. Yang Feng's tiger body couldn't help but tremble, and said strangely in his heart.

"The system will evolve slowly according to the host's completion of each task. ”

"I see, I didn't expect this kind of operation. Yang Feng was a little surprised in his heart, he didn't expect that the system could be upgraded, but now it was better than listening to those cold mechanical sounds.

"By the way, didn't I complete the task before, how do I use that lottery scroll?" Yang Feng lay on the table, seemingly asleep, but he was communicating with the system in his heart.

"The host only needs to say a silent word in his mind to start the lottery. The system said.

Hearing the voice in his head, Yang Feng silently recited: "Lottery ———"

Suddenly, a roulette wheel appeared in front of Yang Feng's eyes, with a total of five square areas on it, which were classified by red, green, blue, purple, and black, and each color displayed milky white fonts, life type, skill type, technology type, special type, and occupation type.

At this time, the golden pointer appeared, began to rotate slowly, passed through one item type, slowly stopped at the skill type, and a golden book popped out and disappeared in front of Yang Feng's eyes in an instant.

When Yang Feng saw the font marked on it, he sighed in surprise: "System, this... What kind of mathematics, physics and chemistry can be drawn? ”

"Didi - mathematics, physics and chemistry are also a skill, so they are systematically classified into the system column, and this is one of the skills that the host will use next, please ask the host if he learns. ”

"Uh..."

Originally, Yang Feng had no interest in learning, but he didn't expect a mathematics, physics and chemistry skill to come at this time, saying that he was a little confused, and he only had a lottery scroll, but he didn't expect it to be wasted like this, it's a pity.

"Let's learn—" Yang Feng sighed a little puzzled, it's better than nothing.

Yang Feng's mind suddenly appeared a series of mathematical, physical and chemical formulas, not only in this world, but also in the universe contained in the mathematics, physics and chemistry knowledge, all kinds of solutions, all kinds of different formulas, vivid and general, he now feels that there is no mathematical, physical and chemical problem in this world can stump him.

As the saying goes, learning mathematics, physics and chemistry well travels all over the world.

Yang Feng seems to have returned to the first year of high school, the period of scholarly popularity, he is now in the science class, with these knowledge of mathematics, physics and chemistry, it is not a matter of being in the top ten of a class? In addition to Chinese and English, mathematics is the most scoring subject, and his Chinese can also be tested seventy or eighty every time, which is calculated, and then get a full score in mathematics, physics and chemistry, at least more than 500 points.

I didn't expect this full-time system to be really powerful.

Yang Feng immediately woke up from the table, cheered up and began to listen to the lecture seriously, this last class was a math class, the teacher was a male teacher, and he had been teaching for several years.

Seeing Yang Feng sitting next to her sit up to listen to the lecture, Han Shilan's beautiful eyes were slightly surprised, and after glancing at him, she ignored him, she just wanted to throw the fruit peel and smash Yang Feng to death now,

However, seeing him listening to the class, Han Shilan's heart was also a little relieved.

In the past, he was sleeping in math class, after all, the content of the teacher's class is very difficult, and if you don't lay a good foundation in the front, you won't understand it later.

Yang Feng listened to the teacher's quick words on the podium, the corners of his mouth rose slightly, and he could understand all of them, what space vectors and three-dimensional geometry, ellipses, hyperbolas, these solutions appeared in his mind.

I couldn't help but start to be a little excited, I didn't expect that what I had lost over the years would be made up, originally when Yang Feng was in the third year of high school, he thought about making up for classes, but the conditions at home were insufficient, and the previous content and foundation also pulled down a large piece of himself, and there were too many knowledge points, and I didn't know when I would make up for it.

If he hadn't given up on himself when he was a freshman in high school, he might still be at the peak of his bookish popularity.

"Let's call a classmate to come up and write this 17-year college entrance examination finale, which of you will come up. The corners of Mr. Dong's mouth were hooked, and he said, "As long as any of you do this problem, I can exempt you from today's math homework... But..."

All the male and female students in the class are panicking, every time the math teacher says this, in fact, it is simply a routine for us ignorant teenagers, who can't do it, and they have to add a wave So, they just want to vomit blood,

"However, you haven't made it or no one has come up, just add a little homework today, don't worry that it won't be too much,"

The corners of Teacher Dong's mouth hooked up with a smile, and he looked at all the students below.

Suddenly, all the students below were talking about it.

"I'll go, you scholar go up quickly, I write my homework until midnight every day, plus a little bit, I guess I fell asleep while writing. ”

"That's it, the top students hurry up and discuss, or I'll have to add homework today. ”

"Just rely on the top students, there is no such thing as us scumbags. ”

“………”

Han Shilan kept writing on the scratch paper with a water-based pen, her beautiful eyes kept looking at the 17-year finale college entrance examination questions on the blackboard, her eyebrows were imperceptible, and her small mouth pouted slightly.

This question is really difficult, and when I thought about the question of the mathematics college entrance examination, I don't know how many people died here.

It is an elliptic curve that calculates one-third of the distance from O to point B, and then proves the moving points of Q1 and Q2.

The corners of Yang Feng's mouth rose slightly, and a trace of disdain flashed in his eyes, this question is equivalent to a college student's question for himself.

Several top students began to gather around a table and discuss, the pen in their hands kept writing on the draft, and their eyebrows were full of doubts, looking at each other.

"It's so difficult——— Han Shilan put down the pen in her hand, her white palm supported her cheeks, and her beautiful eyes stared at the topic she had copied on the scratch paper.

"Is it difficult? I'll teach you. Yang Feng smiled slightly, picked up Han Shilan's cyan water-based pen, and began to make auxiliary lines on her scratch paper, now is the time for Han Shilan to forgive herself, but you have to grasp it.

"Will you? hehe-" Han Shilan's eyelashes twitched slightly, and she said with disdain, if it was before, then he would definitely be, but now...
