In the courtyard.

Lin Chen held an old book and looked at it with relish.

This book records Mr. Yan’s decades of research on the way of formation. There are more than 100 types of formations on it, from simple Qi-gathering arrays to complex chain attack arrays, and each of the formations recorded in it has Mr. Yan’s research experience on it.

With Mr. Yan’s experience, Lin Chen also looks quite relaxed.

"The formation is composed of array eyes and array flags. Some formations also require array plates. The array eyes, array flags and array plates are placed differently, and the array patterns presented are also different."

Lin Chen thought to himself, "The formation is divided into three types, one is the psychedelic array, which is used to trap people. The general psychedelic array can trap martial artists with cultivation below the True Dao Realm. The powerful psychedelic array can't do anything even if the warriors in the Baoyuan Realm can't do anything. The psychedelic array is also divided into many types, such as the formation that can bless the strength of the warrior."

In fact, the Qi Gathering Array is also a type of psychedelic array.

"The second type is the teleportation array. As the name suggests, the teleportation array is used for teleportation. However, there are not many formation masters who can set up teleportation arrays now. There are also extremely precious attribute spirit stones to provide energy by setting up the teleportation array."

There are many types of teleportation arrays, including short-distance teleportation arrays, long-distance teleportation arrays, and even random arrays. For example, the stone platform in the inheritance hall is a small teleportation array.

"The third type is attack formation! This type of formation has extremely powerful attack power. It is rumored that there was a formation master in ancient times who arranged an attack formation to kill the king of the Life and Death Realm."

The difficulty of setting up attack formations is more difficult and complicated than the first two formations, but the power is surprisingly great. Moreover, the formation master arranges the formations at the same time as the psychedelic array and the attack formation. If a formation master is trapped by a formation master, unless this person can quickly break the formation, he will only be detested on the spot. After all, the attacks of the formations are continuous, and even if he cannot kill the people inside for a while, he will be exhausted to death.

The more Lin Chen read this formation book, he felt the vastness of the formation method. The complexity of some formations is incredible. Even if Lin Chen has strong soul power, he was a little dizzy at this moment.

"No wonder Yan always said that he had spent decades and had only realized the essence of the formation."

Lin Chen shook his head. This formation method is impossible for ordinary young people to study the formation method unless it is an old monster who has lived for hundreds of years. After all, it is impossible to study the formation method without decades.

Similarly, Lin Chen is no exception. Although his soul power is strong and he has Mr. Yan’s experience in researching formations, he will not be able to understand the way of formations for a while. This time he watched this book, he only had some understanding of formations and could distinguish the difference between formations.

"Next time, I have to get a set of array tools and try to arrange a simple array." Lin Chen glanced at the book in his hand, flipped his hand, and put it away. "The study of the way of formation is not something that can happen overnight. It's over today. It's time to practice the hidden Qi technique."

Taking out the secret of Hidden Qi Art, Lin Chen buried his head in the process of studying it again.

Compared with the way of formation, the Hidden Qi Jue now has a greater effect on Lin Chen. After all, it will take Lin Chen more than ten years or even decades to study a powerful formation, and it will have no effect on him now. On the contrary, once the Hidden Qi Jue is successfully practiced, it can hide the aura on Lin Chen's body. As long as the enemy's cultivation level does not exceed the second level of Lin Chen, it will have unexpected effects when fighting.

The Hidden Qi Jue is a high-level auxiliary martial arts at the earth level, and it is quite difficult to practice.

However, after Lin Chen's soul power merged with the black fog in the inheritance hall, his soul power increased greatly, and his comprehension ability also increased a lot. In less than half an hour, Lin Chen finished reading all the hidden Qi techniques and had some experience in his heart.

"It's really amazing. The Hidden Qi Art was actually used based on this principle."

After reading the secret book of Hidden Qi Art, Lin Chen couldn't help but admire.

If it were someone else, it would take several days or even months to understand the principle of using this Hidden Qi Art. However, Lin Chen had a strong comprehension, and half an hour was enough for him to understand.

The principle of this hidden Qi technique is to use the true qi of the dantian, or the true energy, to compress a small dot in the body, and then the remaining true qi, the true energy, envelops the ball, making it impossible for outsiders to notice the true cultivation of the practitioner.

"The key point is at this small point. It is not difficult to compress a ball in the dantian, but the important thing is to compress it to an extremely small point. Only in this way can the enemy not notice it."

Lin Chen pondered in his heart. The principle of the Hidden Qi Art is not very complicated in Lin Chen's opinion, but it is a bit difficult to do it. After all, this ball is not a big snowball, but is formed by the true essence. Ordinary warriors can compress the true essence into a ball after spending a little time, but how can they be compressed into a small dot?

As we all know, after the true qi is converted into true energy, its density is very high, and it will be very difficult to compress it. This is like compressing water in the sea into a glass of water, which is incredible.

After pondering for a moment, Lin Chen sat cross-legged on the bed and began to try to compress the true essence of the Dantian.

He released his soul power into the dantian and began to compress the true essence of the dantian. It seemed that the dantian was only a part of the human body, but in fact, it formed a space. As soon as Lin Chen's soul power entered it, he easily compressed two-thirds of the true essence into a ball ten feet high.

"Continue to compress."

Without a stop, Lin Chen continued to control the compression of the true energy.

The ball has changed from ten feet to nine feet, and has the control of soul power, so Lin Chen has no difficulty in compressing it.

Eight, seven zhang,

...

Two zhang, one and a half zhang, one zhang!

When Lin Chen compressed the ball to ten feet, he couldn't help but feel a little pressure. The ball felt like it was broken. If it was broken, it would be a waste.

"According to the records of the Hidden Qi Art, practicing successfully will at least compress the true energy to the size of a fist, otherwise it will be impossible to successfully conceal the cultivation level." Lin Chen thought to himself.

The Hidden Qi Art is clearly recorded that the true energy must be compressed to the size of a fist. Now, even if Lin Chen has strong soul power and strong control power, he has already felt the pressure when he compressed the true energy to 1 zhang. It can be imagined how difficult it would be to practice this Hidden Qi Art if he was another warrior.

Taking a deep breath, Lin Chen continued to compress the ball in his dantian. As Lin Chen continued to compress, the ball was slowly shrinking. After a short moment, the ball was finally only one meter high, but until now, Lin Chen did not dare to continue compressing because he felt that as long as he compressed the ball one centimeter, the ball would explode immediately!

The explosion of the ball will not only fail this practice, but also may damage the Dantian. The consequences of injury to the Dantian are very serious. At the least, it will be seriously injured, and it will be difficult to improve the cultivation level. At the worst, it will be a waste of cultivation for a lifetime, and it will become a waste person from then on.

"This hidden Qi technique is so dangerous to practice." Lin Chen smiled bitterly. As soon as he released his soul power, the ball in his dantian seemed to be a deflated balloon, and disappeared in a blink of an eye.

Shaking his head, Lin Chen began to think about the reason. Since there is the secret book of Hidden Qi Jue, someone must have successfully practiced the secret book of Fruit. There is no reason why the true essence of the Dantian cannot be compressed.

With a flip, he took out the secret book of the Hidden Qi Skill again and started reading it. This time, Lin Chen looked more and more carefully, splitting the recorded texts in the Hidden Qi Skill. This time, Lin Chen saw a trace of mystery.

"There is actually a picture of the mind!"

Lin Chen was stunned. The secret book of the Hidden Qi Art also hid a picture of the Heart Method. Of course, it was not a picture, but a text. What surprised him was that the Heart Method Method was actually hidden in words, as if he didn't want people to see it.

"It's really dangerous. If I forced myself to compress it just now, I'm afraid I'd explode and die." Lin Chen was still scared. The person who created the Hidden Qi Art was too sinister and actually came up with such a strange trick.

However, after Lin Chen found this mind method diagram, it would be much easier to practice the Hidden Qi Art. The Hidden Qi Art diagram is that the true essence of the dantian flows in different meridians in the body, and then returns to the dantian after flowing. The mystery is that it will be much easier to compress after flowing. As long as a warrior with some control can practice successfully.

Lin Chen has strong soul power and extremely powerful control power. With this mind method map, Lin Chen's practice of Hidden Qi Art is a natural result, without any difficulty.

In a moment, two-thirds of the true energy in the Dantian was compressed by him into a ball slightly smaller than his fist.

Then, Lin Chen followed the method of using the Hidden Qi Art to cover the remaining third of the true energy of the ball. With the completion of this last step, Lin Chen's entire aura suddenly dropped instantly, reaching the point where he was only in the middle stage of the Tiangang Realm.

"It really works!" Lin Chen was delighted.

He moved his heart and emitted the compressed ball, and then re-compressed a fist-sized ball. However, unlike the last time, Lin Chen compressed more true energy this time than two-thirds, leaving only less than one-third of the total true energy.

This time, Lin Chen's cultivation aura dropped directly to the early stage of Tiangang Realm.

"call"

Lin Chen smiled on his face, "With this hidden Qi technique, I can control my cultivation to the early stage of Tiangang Realm to the peak of Tiangang Realm."

"However, I should control my cultivation to the peak of the Tiangang Realm. After all, many people know that my cultivation is at the peak of the Tiangang Realm. If I suddenly become the early stage of the Tiangang Realm, it will arouse others' suspicion."

Immediately, Lin Chen compressed the true energy in his dantian again, and suddenly, his cultivation level changed from the early stage of the True Dao Realm to the peak of the Tiangang Realm.

The cultivation level is reduced to the peak of the Tiangang Realm, unless the other party's cultivation level is two levels higher than Lin Chen. For example, Lin Chen is now in the early stage of the True Dao Realm, and others must at least the late stage of the True Dao Realm before they can see Lin Chen's true cultivation level.

After feeling that there was no abnormal movement in the Dantian, Lin Chen came to the courtyard with a steel sword and started practicing sword skills.

Two months passed in a flash. During the two months, Lin Chen stayed in the courtyard and practiced hard every day. He spent two hours in the morning to study the formation, practiced swords in the afternoon, and practiced elixirs in the evening. Of course, the elixirs taken by Lin Chen are now obtained from Wang Dong and others. The elixirs in their hands are most suitable for martial artists in the True Dao Realm. At this moment, Lin Chen's cultivation level just broke through to the early stage of the True Dao Realm and can be taken.

That afternoon, Lin Chen was practicing sword in the courtyard. At this time, the seventh elder walked over with a smile, "Not bad. The reason why geniuses are better than others is that they have better qualifications, but diligence is also very important."

Lin Chen touched his nose and smiled.

The seventh elder suddenly looked serious and said, "Lin Chen, I am here to inform you this time. The Supreme Elder wants you to go over immediately."
