Xingchen still wanted to look for it, he didn't want to give up this opportunity, because once he opened up the Purple Mansion, it was basically impossible to integrate the Chaos Bead into the Purple Mansion. At that time, he can only wait for him to become an emperor, and then find a way to repair this chaos bead, so that he can use the chaos bead to prove the chaos body.

Therefore, after raising his cultivation to the consummation of the physical realm, Ye Xingchen temporarily stopped cultivating.

He first contacted Chen Jialiang and asked him to use the power of the Chen family to see if he could find the crystal nucleus or essence.

After that, Night Star consulted a lot of information on the Internet.

However, what comes out of the search is basically related to games and related things, and there is no record of these two things in the real literature.

There are only two possibilities for this to happen.

Either there are no two things on earth, or no one has ever found them, or they don't have that name.

It's like when they cultivate the true realm, the person who cultivates is called a monk, or a cultivator, but in China, it is called an ancient cultivator.

After the May Day holiday, Ye Xingchen, who decided to stop practicing for the time being, went to school.

After the waterspout incident, the atmosphere in the class is a little sluggish, so far, there are still seven or eight students in the entire third year group have not been found, although the search and rescue work is still continuing, but it is far from the previous strength.

"Night classmate, there is only one month left before the college entrance examination, I want to set up a study group with you, I don't know if you are interested. After class, Liu Yunting took the initiative to find Ye Xingchen, saying that he wanted to set up a study group and work hard for the college entrance examination together.

Although in private, she has always called Night Xingchen as Xingchen, but at school, she still calls Night Xingchen Night Classmate, which is also agreed by the two of them before.

"Okay, can I also participate?" Hearing that Liu Yunting wanted to set up a study group, he didn't wait for Ye Xingchen to answer, but Du Lei was interested.

In order to be able to be admitted to the same university as the girl he likes, Du Lei has simply entered a crazy state of study during this time, and his academic performance has improved by leaps and bounds, which is very obvious.

However, he knows that even if he works so hard now, even if the effect is obvious, there is still a big gap in wanting to be admitted to a first-class university in China.

"Absolutely. ”

If it was in the last semester, Du Lei wanted to join the study group, Liu Yunting would definitely not agree. Because Du Lei didn't study much on weekdays before, let him join the study group, there was no learning atmosphere at all, and if he didn't do it well, it would affect others and make others inert.

But now Du Lei is very knowledgeable, and Liu Yunting can even find the shadow of her previous study in Du Lei, so seeing that Du Lei is so interested, Liu Yunting naturally welcomes him.

"Count me in, count me in. Gu Yihang also came over, he naturally couldn't leave behind such a thing.

"Good ......" Liu Yunting glanced at Gu Yihang a few times, in fact, she wanted to refuse Gu Yihang, because Gu Yihang didn't have the heart to study at all. But she agreed to Du Lei, if she rejected Gu Yihang, I am afraid it would be a little difficult to say, plus if she rejected Gu Yihang, what if Ye Xingchen did not participate because of this? So Liu Yunting also agreed.

The three of them looked at the night star in unison.

After feeling the eyes of the three of them wanting him to join, Night Star finally agreed to join in.

It happened that the third year group had a few unused small rooms, and they cleaned up one of them and used it as a learning classroom.

After school, the four of them gathered here.

Gu Yihang bought a lot of snacks, and before he could start studying, he ate them first.

"I said that you kid are here to study, or are you here to eat snacks?" Seeing Gu, Du Lei knocked on the table and glared at him.

"Hey, hey. Gu Yihang smiled when he saw this, and said: "You don't understand this, if you don't eat the version, how can you have the strength to read." ”

"Fat to you. Du Lei scolded him, and then concentrated on the topic.

Maybe it was because seeing that the three of them were studying seriously, Gu Yihang was also a little embarrassed, so after eating a few more bites, he wiped his hands and picked up the textbook.

"Classmate Liu, will you do this question?" After doing a few questions, Du Lei seemed to be stumped by a function problem, he thought for a while, but didn't come up with it, so he subconsciously asked Liu Yunting.

Liu Yunting glanced at the question Du Lei was doing, and said with a slight smile: "This question, it is indeed a bit difficult, you and his corner, corresponding here, we are here, pass the fixed point, make a line, and then like this, assuming that the element in it is x, and then like this, in this way, you try it......"

Liu Yunting gave Du Lei an answer directly, and did not completely write out the steps of doing the question, but just kept giving Du Lei a little hint, and finally asked Du Lei to try it himself.

Du Lei tried it according to Liu Yunting's method and quickly calculated it.

"Haha, classmate Liu, you are so amazing. After calculating the result, Du Lei was extremely happy, Liu Yunting taught him like this, which would impress him very much, and when he came up with a similar topic next time, he would do it directly.

"Classmate Ye, how do you do this question?" Seeing Du Lei boasting that she was amazing, Liu Yunting was naturally very happy, she quietly glanced at Ye Xingchen, and suddenly wanted to know how Ye Xingchen did this question, whether it was the same as her approach.

Hearing this, Ye Xingchen glanced at this question and said indifferently: "There are two solutions to this problem, one is more troublesome, and the other is particularly simple. ”

"I want to know the simple. Liu Yunting knew that there must be other ways to solve this problem, but she hadn't studied it in detail, after all, the method she was using now felt very simple.

Ye Xingchen nodded, pointed to a line on the scroll, and said indifferently: "You fold this line in half, and then draw a dotted line from here to see." ”

Hearing Ye Xingchen say this, not only Liu Yunting, but even Du Lei also did it.

Soon, both of them figured out to take it.

"Boss, how did you come up with this method, it's amazing!" Du Lei looked at the results on the paper and was very excited. Using Ye Xingchen's method to solve the problem is much simpler than Liu Yunting's just now.

Liu Yunting also looked at the straw paper with an incredulous expression, this is the kind of approach, she feels that she can't think of it even if she wants to break her head.

However, at this time, Ye Xingchen said: "Although it is easy to do this, if you are taking the college entrance examination, I suggest that you do not use this method of solving the problem." ”

"Why?" Hearing Ye Xingchen do this, Du Lei asked with some puzzlement.
