The other students were amazed.

Jiang Feng, is it sure that he is the guy who used to be at the bottom of the whole grade in almost every big exam, he was lazy and lazy every day, and he had no sense of existence?

"Anyway, after class today, I have to kill him. Although Tie Hai was shocked, the humiliation he received was too great, so that his thoughts did not waver in the slightest.

"Since he caused such a big sensation as soon as he came, it will not affect my status in the future, and this person cannot be kept. An Chaodu thought to himself, his eyes were extremely dark.

"It's really a little embarrassing, this person, suddenly entered the palace for the second time, and his shot was extraordinary, it seems that he has indeed been reborn, and he is no longer the Jiang Feng before. Ye Qian's psychology was up and down, and he couldn't make up his mind.

Almost all of the other twenty or so students who wanted to fight Jiang Feng on the life and death platform were greatly shaken.

After Teacher Gu praised Jiang Feng, he continued to explain the theoretical knowledge of the Wheel of Spells.

"The Wheel of Spells can be understood as a structure of laws that condense the mana of a larger scale. The more delicate, accurate, and massive this structure is, the higher the level of the Wheel of Law and the greater the burst of elemental mana. ”

"Then, the ability to first draw the wheel of spells with your hands and then with your spirit determines the ability to harness elemental mana. ”

"It's about mental power, it's about daily observation, it's about visualization. It is more related to arithmetic, the knowledge of the structure itself. However, the Datong Empire was still extremely backward in terms of arithmetic and structure, so the wheel of spells mainly relied on the accumulation of experience, and there was no systematic cultural norm. ”

"Legend has it that tens of thousands of years ago, civilization flourished, and there was a rare scientific and technological civilization that was more developed than now. Only later, I don't know why that civilization suddenly disappeared. Spells have been lonely since then, and now, in the Empire, and even on the entire associated planet, spells are at an extremely low level, and physical cultivation is the mainstream. ”

Teacher Gu roughly explained the ins and outs of the spell.

Jiang Feng can also understand that on the companion planet, spells are indeed not the mainstream, and the assistance is okay, but it is still far away to burst out with terrifying power.

Physical cultivation is much stronger than Fa cultivation.

This is because the Wheel of Spells is really a vast and systematic project, and after a civilization fell lonely tens of thousands of years ago, many systematic studies must have disappeared, and if you want to establish a system that supports the Spell Era, you need to study from top to bottom, tens of thousands of years, which is almost unimaginable.

Physical cultivation is like a person throwing a punch, which is very simple.

Elemental law cultivation, just like people want to absorb natural elements, condense an elemental fist, and then strike accurately at a certain place, it is very difficult, condensing the shape and structure of this elemental fist need to be accurately calculated, in order to grasp the perfection and burst out the real power, this is obviously not a short-term effort.

Teacher Gu then sketched out a few first-order spell wheels, all of which were relatively simple, so that everyone could memorize and understand.

However, almost every student scratched his ears and cheeks, and he didn't know why.

And Jiang Feng saw it in his eyes, but he had some different ideas.

These first-order spell wheels are actually some line relationships, very coarse and shallow, and with such a shallow structure, Teacher Gu or the entire Ninth Academy does not have a systematic arithmetic discipline to accurately express it.

As soon as Jiang Feng raised his hand, the two first-order spell wheels had already been applied by him, two horizontal and vertical water lines, the same length, very vertically crossed into a cross, flying outward, and the trajectory was also very accurate.

"Poof. The two waterlines hit Qin Xue's face, making her feel excited, and she stood in place in a daze, blushing and saying angrily, "Classmate Jiang Feng, you deliberately humiliated me, right?"

"I'm sorry. Jiang Feng's face was expressionless, "This may help you comprehend the Wheel of Spells." He added.

"Classmate Jiang Feng, why is your grasp of the Wheel of Spells so accurate? Not only is the length of the waterline the same, the angle is also vertical, and even the trajectory of the launch is exactly the same, so far away, can you accurately hit the face?" Teacher Gu was shocked.

Jiang Feng walked towards the podium, picked up the pen, and said, "Teacher Gu, don't mind if I write and draw on the blackboard." ”

Teacher Gu signaled that there was no problem.

Jiang Feng wrote while teaching to solve his doubts, "The first-order spell wheel is actually a line relationship, if we want to make him more accurate and burst out with more practical power, we have to use a standard to regulate him, so that he is not bad." ”

As he spoke, Jiang Feng drew two arrows on the blackboard.

"I define these two arrows as X, Y, this is like a coordinate, all the line relationships, can not escape this coordinate, the length of the spell wheel, can also be accurately defined by X = how much, Y = how much. I don't know if you can understand this. ”

After Jiang Feng finished speaking, he didn't say anything more, put down the pen and left the podium, he would definitely only point to the end for the time being, and it was impossible to teach him.

Immediately, Qin Xue stood up, her face flushed, and she said shyly, "Classmate Jiang Feng, what you said is too profound, I was like you just now, I seem to understand a little, but I still think this is profound enough, I don't know if you can still explain it carefully." Or after class, give me a private lesson, if you don't mind. ”

Qin Xue's voice was weak, and she slowly lowered her head as she spoke, becoming more and more shy.

Then, a few other classmates stood up one after another, and they were all female classmates.

"Classmate Jiang Feng, what exactly is this X, Y, we think it is very mysterious, it seems that we don't understand, are you sure that you are from the companion planet? I don't know if you can go to my house after class and explain it to me alone. ”

Jiang Feng's coming out really shocked the students.

Especially those female classmates who didn't say that they challenged Jiang Feng on the stage of life and death before, they were all deer at this time, and they wanted to take the initiative to invite Jiang Feng to their house as soon as possible and be alone with them.

"Sorry, I may not be available. Jiang Feng glanced at Qin Xue slightly, then glanced at the other female classmates and said.

When Teacher Gu heard Jiang Feng's explanation, he only felt that his brain was wide open and he was ecstatic.

"Jiang Feng, this is definitely a big systematic breakthrough, it may have a qualitative leap in the basic arithmetic of the empire, as well as other disciplines, which may shorten the time for the evolution of the imperial civilization forward by a hundred years, a thousand years. ”

"There will be a meeting in the afternoon. At the meeting, I would tell the second-grade school committee about it, and then quickly report it to the school committee. ”

"That's the end of today's lesson, of course it's good that everyone can understand, but if you can't, go back and figure it out for yourself. The content of today's class, everyone must keep it a secret and don't tell anyone. This is definitely a time-changing systematic arithmetic knowledge. ”

Teacher Gu was "ecstatic about the poems and books", and Jiang Feng informed him, and quickly left the classroom with the books, as if he was going to rush to the meeting to report today's amazing results.
