At this time, it was already eight o'clock in the evening, and the villa of Tang Li's family was still brightly lit, as bright as day. Pen ~ fun ~ pavilion www.biquge.info

Xi Yue stood alone in front of a small blackboard, playing with the apple in his hand with his slender fingers.

In front of him, Tang Li and Qi Weijiang were accepting their tutoring with distressed faces.

For Qi Weijiang, being a guest at Tang Li's house should have been something he had always dreamed of, but once it was involved in learning, the lazy tendon on his body began to vaguely feel the faint malice from Xiyue, and kept reminding his master to be careful of the lecturer of the same age as him in front of him.

As far as Tang Li is concerned, she thinks that she has no need to accept Xiyue's tutoring, not to mention that Tang Li's original grades have always been among the best in school, and the only mathematics that is a short board has also grown significantly after gaining calculus ability, she feels that she now has the possibility of impacting the top ten in the school year, and she doesn't need Xiyue's tutoring at all to help herself go further, for a rich man like her, getting the first place in the exam actually doesn't mean much to her.

Xi Yue didn't have time to think about the thoughts of the two of them at the moment, if tutoring Qi Weijiang was just his whim, Tang Li's mathematical foundation making up for it was crucial for the future battle.

The key to how to use calculus more creatively lies in the user's own mathematical foundation.

Tang Li may think that relying on the current calculus ability alone is enough to deal with most of the scenes, and the computing speed like a supercomputer is already cool and dazzling, but Xiyue knows that this is not the limit of what calculus can do.

Lu Liu may make a move at any time, with the current combat strength of Xiyue's side, if you want to directly confront Lu Liu, who has mastered the three laws of mechanics, the victory rate will not exceed 30%, in order to really improve your own victory rate, Xiyue must do everything possible to accumulate strength and prepare for the final battle that may come at any time in the future.

After Xiyue finished eating another apple, it was time to rewind.

Xi Yue retrieved the test paper in the hands of the two, and after a brief glance, he couldn't help frowning, and said to Tang Li and Qi Weijiang: "There is less than a month left before the final exam, and it is impossible to improve quickly during this time, if you want to get good results, it seems that you can only use the No. 2 plan." ”

"Plan No. 2?" Qi Weijiang looked at Xiyue with a puzzled expression.

Xi Yue took out a blank piece of paper from the table beside her, and after folding it a few times, tore it into several small squares and placed it in front of Tang Li and Qi Weijiang.

"Plan No. 2 is to write a cheat sheet. Xiyue said solemnly.

After hearing the cheat sheet, Qi Weijiang showed a look of sudden realization, and said to Xiyue: "It turned out to be a cheat sheet, which is much easier to understand, and a cheat sheet can indeed improve your grades quickly." ”

Tang Li obviously didn't approve of Xiyue's plan to write a cheat sheet, just from the expression on her face now, you could see some clues, just listen to her say to Xiyue in a yin and yang tone: "I thought that the smart Xiyue classmate had some tricks, aren't you just teaching us to cheat?"

After hearing that Tang Li was somewhat disdainful of cheat sheets, Qi Weijiang immediately turned around and began to count the disadvantages of cheat sheets.

Xiyue didn't pay attention to Qi Weijiang's constant noise in his ears, he looked at the two of them seriously, and said sharply: "Do you really know how to write a cheat sheet?"

In order to show a little in front of Tang Li, Qi Weijiang took over Xiyue's words and said, "Isn't it easy to make a cheat sheet?

After listening to Qi Weijiang's opinions, Xi Yue showed an expression that was really so, picked up a blank small square, pointed to it and said: "Writing a cheat sheet is not as simple as you imagined, in such a small space, you can only leave a few contents, as the key to winning in the exam, Tang Li, if it were you, what content would you leave on this piece of paper when writing the cheat sheet?"

"My words, my words are not going to write cheat sheets at all, and besides, this kind of cheating thing, no matter how good it is, is not my true level, and it will not help me improve myself at all. To be honest, Xi Yue really didn't expect that Tang Li, who would use calculus to cheat in the math exam, would use such a righteous and awe-inspiring expression to criticize the writing of cheat sheets, is it not considered cheating in her opinion?

In desperation, Xiyue had no choice but to ask Qi Weijiang again: "What about you, what will you write on it?"

"Me?" Qi Weijiang grabbed his scalp, looked at the small note in his hand, thought hard for a while, and said to Xiyue: "If I have to write, I should write down the content that I may have to take in the next exam, as well as the things that I usually forget the most, after all, in this place, I must definitely write the content that can get the most points." ”

"That's right, that is, on the basis of predicting the content of the next exam, you will add your weak points in learning, integrate them, extract the best parts, and write them all on the cheat sheet, right?"

"Oh, it seems that this is indeed the case, listening to your analysis, it seems that it is not very easy to make cheat sheets. Qi Weijiang nodded subconsciously, and it seemed that he had begun to be affected by Xi Yue's views.

Xi Yue, on the other hand, continued to strike while the iron was hot, and said to the two: "I asked you to write cheat sheets, not so that you can rely on cheat sheets during the exam, what you need to do now is to write out the cheat sheets and destroy them step by step." ”

"Eliminate the cheat sheet?" Tang Li chewed these words repeatedly in his mouth, and suddenly seemed to have an understanding, and his eyes sparkled and said to Xi Yue: "Oh, I see, what you mean is that we want to sort out all our weak links by writing cheat sheets, and then overcome them one by one, right?"

"Oh, I see, I understand, I didn't expect cheat sheets to have this effect. Qi Weijiang also nodded incessantly, echoing Tang Li's point of view.

Seeing that the two of them finally understood what they meant, Xiyue's face did not show any expression of relief, in his opinion, this was the result of course, and there was nothing to be thankful about.

At this moment, outside the door, Qin Yixing's pale face suddenly appeared in Xiyue's line of sight, as if he had something to say to him.

After explaining a few words to the two who were trying to write a cheat sheet, Xi Yue walked out of the door and talked with Qin Yixing in the corridor.

"You look worse now than you used to. Although Qin Yixing listened to Tang Li's request and began to use anti-cancer drugs to fight against cancer cells, his physical condition was worse than before the treatment due to the large reduction in the number of white blood cells in the body caused by anti-cancer drugs.

Qin Yixing smiled bitterly and said to Xi Yue: "This may be fate, I have already accepted this fact, don't we have more important things than this? ”
