In the sea of Gu Yue's soul, Li Qingyun's soul flashed from the spatial passage.

"Senpai!"

Seeing Li Qingyun coming, Gu Yueying hurriedly shouted respectfully to her seniors.

"Gu Yueying, can you give me the Mixed Yuan Demon Skill you cultivated?" Li Qingyun asked Gu Yueying.

"Senior, I don't know what you want to do with the Mixed Yuan Demon Skill?" Gu Yueying asked.

"I just met another human monk, and then I reached a cooperation with him, but he can't absorb the exercises of human true yuan, so I'm going to find one for him." Li Qingyun told the truth.

"In this way, I can hand over the Mixed Yuan Demon Skill to my seniors." Gu Yueying hurriedly said.

She didn't use the Mixed Yuan Demon Skill to bargain with Li Qingyun.

Li Qingyun was very satisfied with Gu Yueying, which also made him have more good feelings for Gu Yueying.

In about ten minutes, Li Qingyun memorized the content of the Mixed Yuan Demon Gong cultivation method.

The content of the Mixed Yuan Demon Skill was much less than his Jindan Dao cultivation method.

However, it can also be understood that Li Qingyun's Moon Shadow Immortal Sutra is a normal cultivation technique. And the Mixed Yuan Demon Skill that Gu Yueying gave him was only an auxiliary exercise.

"Senior, since you're here, let's make a deal." Gu Yueying said to Li Qingyun.

"Okay." Li Qingyun nodded.

"Senior, wait a minute, I'll go get the real yuan." Gu Yueying said to Li Qingyun.

Li Qingyun's spiritual sense also spread out from Gu Yueying's soul sea, so he saw Gu Yueying come to the place where several Jindan monks were imprisoned, and then used the Mixed Yuan Demon Attack to absorb the true elements in the bodies of several Jindan monks in turn.

When Gu Yueying had absorbed all the True Yuan of the Jindan Cultivators, a fist-sized True Yuan Group had condensed in her soul sea.

"Senpai, here you go." Gu Yueying handed the fist-sized True Yuan Group to Li Qingyun.

"That's so much this time!" Li Qingyun was also surprised.

"This is just the beginning, when I catch more Jindan monks in the future, there will be more and more true yuan in the transaction." Gu Yueying said to Li Qingyun with a smile.

"I'm looking forward to that day."

Li Qingyun nodded, then opened the spatial passage and returned to the Heavenly Demon Realm.

When Li Qingyun returned to the Heavenly Demon Realm, the fist-sized True Yuan Group had already become the size of an egg.

After Li Qingyun divided this mass of energy into two parts, he sent it to Gu Yueying.

It didn't take long for Li Qingyun to come to Shi Jianqiang's soul sea again.

"Senpai!" Seeing Li Qingyun, Shi Jianqiang hurriedly shouted.

"I'll pass you on an exercise, you can memorize it." Li Qingyun said lightly towards Shi Jianqiang.

After more than an hour, Shi Jianqiang finally remembered Li Qingyun's teaching of his exercises.

After teaching Shi Jianqiang the Mixed Yuan Demon Skill, Li Qingyun went back.

The Mixed Yuan Demon Skill is only an auxiliary cultivation exercise, and it does not affect the cultivation of the main exercises, so Li Qingyun decided that he will also try to cultivate after returning to the earth, and maybe he will be able to use it when he can.

His situation is special, even if he absorbs other people's true yuan, he doesn't have to worry about any true yuan mixed up.

Because he can use the Heavenly Demon Soul Body to coerce other people's True Yuan into the Heavenly Demon Realm, and then when he returns, the True Yuan will become pure energy.

After Li Qingyun's soul returned to Earth, he opened his mobile phone and looked at it, it was already more than four o'clock in the morning!

Li Qingyun heard the sound of talking in the living room outside, it was the sisters Chen Yifei and Chen Jiaxin talking.

The two of them should have met when they were hungry and came out to eat.

Chen Jiaxin eats in more than forty minutes, and Concubine Chen Yi eats in half an hour, so she can meet countless times in one night.

In Li Qingyun's soul sea, there was pure energy the size of half an egg, and these were all his trophies tonight.

With so much pure energy, he would definitely not be able to absorb it all today, and it was estimated that it would take several nights to absorb it all.

The first time Li Qingyun got a ball of pure energy the size of an egg from the Heavenly Demon Realm, he absorbed it for three days and three nights before he absorbed it all.

"I wonder if the pure energy can be stored in the spirit storage stone?"

Li Qingyun suddenly thought of the spirit storage stone given to him by his master Sun Qingwei.

The Spirit Stone can store True Qi, which can replenish True Qi when it is insufficient when breaking through the foundation.

If Shi Jianqiang had a spirit storage stone to store a large amount of his true qi, he might not have almost failed to build a foundation.

After Li Qingyun thought about it, he mobilized some pure energy, and then entered it into the spirit storage stone.

Li Qingyun didn't dare to input too much, for fear that the spirit storage stone would not be able to preserve the pure energy, so that the pure energy would dissipate in vain.

"Alas! It seems that this pure energy can be stored, alas! "Li Qingyun discovered the wonderful use of the spirit storage stone.

However, after thinking about it, he found that this spirit storage stone didn't seem to be of any use.

Because the pure energy can be stored in the soul sea, he doesn't need to store it in the spirit storage stone at all.

Moreover, the storage space of this spirit storage stone does not seem to be very large, and it can only store about a thousand filaments of true qi energy.

It didn't seem to do much to him.

When he built the foundation, he could store some more pure energy in the soul sea.

A thousand traces of true qi may not be of much use to him, but it is better than nothing.

Two days later, it will be the National Day holiday.

On the day of the National Day, Li Qingyun helped Grandpa Chen and Grandma Chen cultivate a trace of true qi.

In the end, only Chen Xiaoxiao was left who had not yet started cultivating.

"Qianqian, I can't go to the mountain tomorrow because I have something at home, you can go by yourself."

On the day of the National Day, Chen Jiaxin called several of her good friends.

And Li Qingyun went to the school to find Teacher Luo to make up lessons for him.

Li Qingyun decided to take advantage of the National Day holiday to finish all the knowledge points in high school.

"Mr. Luo, after I finished learning the knowledge points of high school, I want to take university courses, I wonder if Mr. Luo can you get the university textbooks?" After the make-up class was finished that day, Li Qingyun asked Teacher Luo.

"University textbooks, yes, you can buy them in the library, you can buy them online, and you can also check the electronic version of the textbook."

Teacher Luo said to Li Qingyun: "If you want to graduate from university and finally want to graduate, it is not enough to learn the knowledge above the textbooks, you also need to read some professional books." ”

"Of course, you first have to have a direction of study or choose a major, so that you can learn better."

Hearing Mr. Luo's words, Li Qingyun thought for a while and said, "I just want to learn advanced mathematics, theoretical physics, chemistry, and so on." ”

"These books are also sold online, and you can buy them on Taobao and JD.com."

Teacher Luo said to Li Qingyun: "To be honest, except for some knowledge at the undergraduate level of advanced mathematics, I don't know much about the rest.

For example, you want to study theoretical physics, including mechanics, quantum mechanics, fluid dynamics, physical dynamics, field theory, string theory, etc., I have not studied any of these!

You know, I'm just a high school Chinese teacher, so if you want to learn this, I can't actually teach you. ”

Hearing Teacher Luo's words, Li Qingyun nodded and said with a smile: "It's okay, I have a way then." ”

Li Qingyun's method is very simple, that is, to memorize everything first, and then go to college if you don't understand it, and then ask the teacher for advice, how simple it is.
