Between classes, Chu Yunfan swept the textbooks on the tablet, if he wanted to be admitted to the key class, not only must he be good in martial arts, but also in literature, he has pulled down a lot over the years, and now he has to make up for it.

"Yun Fan, do you really want to make an appointment with Feng Deying?" Next to him, Gao Hongzhi asked again and again, he came late today, but he also heard about it later.

There is no way, this matter is very troublesome, Feng Deying is the class president in their class, and even other classes in the grade are famous.

Compared with Feng Deying, Chu Yunfan is just an ordinary student, before that, only the students in the class knew about him, and now the two are actually going to fight in half a month, no matter from which point of view, it is big news.

Even the teacher was shocked by this matter, but after investigation, it was indeed Mu Zhenfei who took the initiative to take action against Chu Yunfan, so he didn't do anything to him, just educated him a few words and asked him to pay attention in the future, so he didn't say anything.

On the contrary, it was Mu Zhenfei who took the initiative to provoke, and was also injured by Chu Yunfan, especially that arm, which has reached the standard of hurting muscles and bones, and is still being treated in the infirmary.

"Well, yes, that's right, he has been looking at me for a long time, instead of letting him make trouble for me so deliberately, it is better for me to take the initiative first!" Chu Yunfan nodded and said, "You have heard about what happened this morning, Mu Zhenfei suddenly came to me for trouble, although it was because Mu Zhenfei broke through to the blood exchange period and wanted to find the relationship on the field, but I suspect that Mu Zhenfei can break through to the blood exchange period, most likely because he can't get rid of Feng Deying!"

"That's right, I went to inquire just now, Mu Zhenfei has spent the past two days at Feng Deying's house, hehe, in order to find trouble for you, our senior squad leader must have made a lot of money, but Mu Zhenfei was actually killed by you in seconds, now let's see if he has the face in front of you!"

Gao Hongzhi smiled and said: "But you also have to understand, although Feng Deying's guy is very annoying, but his strength is real, even I am not sure that I will be able to defeat him, now although everyone says that you are powerful, but in the final analysis, you are only in the blood exchange period, which is still far worse than the qi cultivation period!"

"You can rest assured about this, since I dare to make an appointment with him in half a month, I am sure that I can defeat him!" Chu Yunfan said lightly.

"Now that you're sure, if you need any help, just call me!"

Gao Hongzhi saw that Chu Yunfan had already made up his mind, so he didn't say anything more.

"But how did you suddenly become so strong in the past few days, don't you fool me with words to fool others, they don't know, I don't know you yet, a few days ago it was still the fifth level of internal strength, and it has only been a few days that it is already the seventh stage of blood exchange?" Gao Hongzhi couldn't help but ask.

In the Kunlun Era, this kind of thing asking about other people's cultivation secrets was a big taboo in itself, and Liu Yushu was also interested in Chu Yunfan's transformation, but she knew that she couldn't ask.

But Gao Hongzhi is different, the relationship between the two is so good, so he is not afraid of this taboo.

"I said I got the hang of it, believe it or not!" Chu Yunfan grinned and said, he had a good relationship with Gao Hongzhi, if it was an ordinary thing, naturally there was nothing that could not be shared, but this time it was different, he knew that once this secret was leaked, the consequences would be unimaginable.

It's not just that he might die, it's even his family!

Even if Gao Hongzhi is his good brother, he doesn't plan to tell it, this secret will only accompany him for the rest of his life, until he enters the coffin!

He could only secretly say sorry in his heart.

However, he said that he was enlightened, in fact, this statement is not wrong, but his whole body has been reborn, but it is not just as simple as opening his head.

Gao Hongzhi glanced at him, and then said: "I believe it, forget it, anyway, I don't have that much interest, I just need to know, you are my good brother, I only have one request, give me a good beating, that kid cherishes his reputation ruthlessly, I looked for him a few times, he didn't respond, you have to help me take a good breath!"

"Yes, no problem!" Chu Yunfan said with a smile.

Since Chu Yunfan dared to say so, he was absolutely sure.

In the cultivation of the physical realm, the seventh is the blood exchange period, and the eighth is the inner vision period, this stage is difficult to say, simple and simple.

Inner vision, this internal vision does not mean that you can really see the situation in the body, but when the mastery of the body reaches a certain level, all kinds of conditions of the body can be reflected in the mind, which is the so-called internal vision.

This stage requires that after so many previous enhancements to the body, the control of the body has reached a fairly precise level.

At this point, it will be able to show some strange abilities, for example, if a place is injured, it can even control the muscles near the wound and automatically stop the bleeding.

Many people are stuck for a year, or even two years, at this stage, because it is too brain-draining to control everything up and down the body at the same time.

Even if you reach the realm of inner vision, you will generally not easily enter this state.

And Chu Yunfan's control of the body, after the transformation of the mysterious power, has reached a very high level, plus his Tiger Demon Fist has also cultivated to the realm of supernatural power, although it is only a basic boxing method, but in the process of cultivation, his control of his own body has also reached a level, otherwise it is impossible to perfectly reproduce the Tiger Demon Fist and play a supernatural effect.

What it takes an ordinary person to master in half a year, or even a year, now he only needs to master it systematically and holistically, and it doesn't take him a few days.

At that time, he will be the real inward period!

The most important thing in this stage is to cultivate enough true qi, and with this breath of true qi, it will break through the dantian located in the abdomen and form a stable sea of qi.

The key to this step is to cultivate qi, which originally needs to be raised for a long time, because impacting the dantian and opening up the sea of qi is actually a very dangerous process.

If the true qi is insufficient, it will not be able to break through the qi sea, but it will cause huge damage to the dantian, and it may even be impossible to reach the qi sea realm in the future.

And this process, you can also use pills to speed up the process, whether it is a super ancient civilization or a modern civilization, there is a pill called Qi Nourishing Pill, swallowing it, you can increase a lot of true qi, accelerate the completion of the Qi nourishing period.

However, this kind of pill is also very expensive, no less than the Forging Body Pill, and it costs 100,000 yuan, which is not something that ordinary people can consume, and it is generally consumed by those who have some surplus money at home.

In modern society, a pound of ginseng grown in mass production is only about 100 yuan, and taking it for a long time can also improve one's own physique, but that process is too long.

This is the relationship why the price of the pill remains high, the pill can shorten the cultivation time considerably, and the value is not the medicinal materials, but the ability to refine the medicinal materials into the pills.

However, the effect is also very significant, and an ordinary person can complete the cultivation of the Qi cultivation period with one Qi Cultivation Pill, which can save a year, or even several years of Qi cultivation effort.

In the past, when the civilization that had not yet excavated the alchemy system and no one knew how to refine the alchemy, those martial artists had to be cultivated for several years just during the qi cultivation period.

Therefore, although the Qi Nourishing Pill is expensive, it is excellent value for money, and in modern times, there are no complete poor people in the real sense, as long as ordinary families are willing to grit their teeth, they can also afford it.

However, this is not enough for Chu Yunfan, he is cultivating the "Heaven and Earth Emperor Extreme Skill", the width of his meridians, and the strength of his body are several times that of the same level.

But in the same way, it is much more difficult for him to attack the dantian and open up the sea of qi than ordinary people, one qi cultivation pill is enough for ordinary people, he needs at least three or more, at least 300,000, plus he still has to complete it in the shortest possible time, then at least two more.

In other words, he at least had to find a way to earn another 500,000 yuan, and he only earned 180,000 yuan as a sparring partner for Liu Yushu for a month, and he also advanced 100,000 yuan, which was not enough to pay the price of the Qi Nourishing Pill, even if it was his own alchemy.

Now he really understands that it is not for nothing that the ancients included wealth in the four major elements of cultivation, but it is completely correct.

It's really time to put a money-making plan on the agenda!
