In the room full of strange fluctuations, Chu Tian sat cross-legged by the window, and between the fluctuations of his divine soul, the spiritual thoughts that filled the Mud Pill Palace to a certain extreme rotated, forming a silver spiritual thought vortex.

In the center of the whirlpool that is accelerating and rotating, it is the divine soul that is the spiritual hub, and as the rotation progresses, the spiritual thoughts continue to pour into the divine soul, and above the divine soul, the light gradually becomes brighter.

There are fewer and fewer spiritual thoughts in the Mud Pill Palace, and they are all like a hundred rivers returning to the sea, and his divine soul is withdrawn, and the surroundings of the divine soul begin to release dazzling light.

When all the spiritual thoughts withdrew from the divine soul, the light was already extremely strong, almost illuminating the entire Mud Pill Palace, and then gradually converged, and the divine soul seemed to turn into a silver star, swallowing the light, forming an irregular circle of light around it, and flickering incessantly.

The aperture gradually narrowed, forming a pure and bright layer of water light on the surface of the divine soul, and as the water light surged, the illusory divine soul became condensed at a speed visible to the naked eye, and its eyebrows and facial features became clearer.

This is the most critical step in the upgrade of the teacher, which is called soul washing. With every upgrade, it's an inevitable process.

When the strength of the soul reaches a certain level, it can release spiritual power, condense on the soul, condense into a light like water quality, surging on the soul, and the quality of the soul will be one step closer, as if the soul has been washed, so it is called soul washing by the image of the masters.

As we all know, condensing spiritual power into a divine soul is a sign of achieving the position of a ninja, as long as this realm is stabilized, it can be regarded as the level of a first-level nenshi.

Like Chu Tian, whose divine soul strength is strong enough to condense his spiritual power into a soul-washing light, he truly has the qualifications to impact a second-level Nian Master. As long as the process of soul cleansing is completed, so that the soul undergoes a thorough cleansing, it can be regarded as a second-level reading master.

Generally speaking, in the process of upgrading the nunji, a total of three soul cleanses are required, the first soul wash is successful, and you can be promoted to the second-level nun-master, which is comparable to the mid-stage of the qi cultivation, and the second soul wash can be promoted to the third-level nhan, which is comparable to the late stage of the yunqi, and the third soul wash is naturally promoted to the fourth-level nenji.

On the mainland, the fourth-level Nianshi has a world-like difference from the first three, and is also known as the Great Nianshi in the industry, and its status is equivalent to that of the Huagang Realm martial artist, and because the threshold for spiritual cultivation is higher, it is much rarer than the Huagang Realm.

Three soul cleansing, the difficulty increases, each time is much more difficult than the last time, especially the last time, it is particularly dangerous, its difficulty is enough to make thousands of spiritual cultivators restrain their hands, I don't know how many people in the last soul cleansing, can not withstand the pain suffered by the soul in the process of soul washing, the soul is damaged, and even broken.

At that time, the regression of spiritual cultivation is still the strongest result, and the heavy ones will even go crazy, become vegetative, and die directly in doubt.

Although Nian Shi sounds extremely beautiful, after cultivating to a high and profound realm, he can also master more lethal power, but the happiness and hardship behind it are by no means imaginable by ordinary martial artists.

The body is damaged, and in most cases, it is just that it can't be cultivated, but it can live a normal life, and there is no problem, but if the soul is lost in the slightest, the whole person will become an idiot, mentally retarded, and even have no basic self-care ability.

In spiritual cultivation, every time you level up, you have to face such dangers, and the success rate of promoting to a great master is extremely low, and a hundred third-level masters who have hit this level may not be able to have a successful one, and the success rate is less than one percent.

What's more, among these people, there is no ordinary person at all, who can achieve the position of a teacher, he is a talent who is one in a hundred, and he can spend two soul cleanses, be promoted to a third-level teacher, and touch the bottleneck of the great master, it is even rarer.

However, for this group that can be called an absolute elite, the winning rate is also so low, and the difficulty can be imagined.

It's not that easy to wash your soul every time, even if it's the first time you wash your soul.

When the light of soul washing washed away, Chu Tian only felt a tingling pain in his brain, which was the inevitable result of the transformation of the divine soul, but Chu Tian felt that this kind of stinging pain was completely bearable, but it was quite unexpected.

"This soul-washing pain seems to be far less terrible than it is rumored to be. Chu Tian felt the degree of stinging pain, and was slightly stunned.

Last time in the secret realm, he collected a lot of messy books, and took advantage of his free days to pick out a few books related to the teacher to read, among which the pain of soul washing was greatly promoted, so that Chu Tian was afraid like a tiger, and even made full psychological preparations in advance.

His breakthrough this time did not necessarily succeed, but he tried to test it, and he did not have the idea of finishing his work in one battle.

In Chu Tian's original plan, once he found that something was wrong, he would disperse the light of soul washing as soon as possible, absorb the experience of failure, and be more confident when he broke through next time, so that if he tried a few more times, he would always succeed a few times.

This is also the safer way that the books say.

The most important thing about the breakthrough of the teacher is to be safe, it is better to fail, but also to ensure that the soul is not damaged, if it is rash and the soul suffers a mistake, it is difficult to repair, and there is no future.

In fact, he didn't know that after all, he was in the bloodline of the ordinary spirit demon clan, and the place where the soul was condensed was essentially different from others.

The soul of an ordinary person is condensed by ordinary spiritual power, and his spiritual mind is condensed by spiritual thoughts, and spiritual thoughts, as a fusion of spiritual energy and spiritual power, the condensed divine soul itself is superior to ordinary divine souls.

Therefore, this first soul cleansing may be considered a difficult level in the eyes of ordinary scholars, but in front of Chu Tian, it is no longer so insurmountable.

Of course, this is only the first time, and the difficulty after that is even greater, the third soul cleansing of the promotion to the Great Nian Master is a threshold of life and death for anyone, even if it is Chu Tian, it will never be as easy as today.

"There's play. Chu Tian smiled, and immediately closed his eyes, observing the changes in the divine soul in the Mud Pill Palace under the action of the washing light, and the smile on his face became even stronger.

He could clearly feel the increase in the strength of his divine soul, and according to this trend, when this soul cleansing was completed, the quality of his divine soul would be raised to a big level.

Sure enough, there is a major difference between the second-level master and the first-level teacher that cannot be ignored.

Although things went far smoother than expected, Chu Tian did not dare to slack off in the slightest, the breakthrough in spiritual cultivation was always lurking in crisis, if there was negligence, once it caused unpredictable consequences, no matter how much regret it would be useless.

He has always been divided into his mind to observe every change in the soul in detail, and once there are bad signs, he will respond as soon as possible, and be ready to cut off the possibility of breakthrough at any time.

The light in Chu Tian's eyebrows flickered slightly, and in the mud pill palace in his mind, the soul-washing light condensed by the pure spiritual thoughts was rolling and surging, like a silver tide washing over the reef by the sea, with a fixed law, washing the divine soul wave after wave.

Above the soul, the silver light became deeper and deeper, the outline of the soul villain was clearer, and the facial features were more distinct.

Although the intensity of soul cleansing was as always, and there was no improvement, the pain suffered by the divine soul was accumulated to a level that stabilized to the point of palpitations as time progressed, and the soul cleansing time was not too short, so many spiritual cultivators fell in this process.

However, due to the fact that Chu Tian's Divine Soul was far stronger than ordinary people, when the Soul was cleansed, the extent to which the Divine Soul suffered was very small, and even if it continued to accumulate, it was difficult to break through the limit that he could bear.

About an hour later, Chu Tian suddenly opened his eyes, and there seemed to be a strange light of energy in his silver pupils, and his divine soul naturally fluctuated, and the rolling spiritual thoughts surged out like an angry tide, passing through the Mud Pill Palace, and spreading to the entire hut in waves.

Many items in the room were suspended in the air, clothes were suspended from the hangers, suspended in the air, like kites flying over and over again, teapots and vases were also suspended in the air, trembling slightly, cracks spreading, and then they were afraid to burst open.

Chu Tianlian retracted his mental fluctuations, many items lost their barriers, and fell to the ground one by one, the solid ones shook slightly, the fragile ones shattered to varying degrees, and the fragments of vases and teapots were scattered all over the ground.

Although the movement caused by spiritual cultivation was much weaker than that caused by Yuan Qi cultivation, after all, he had reached a considerable level and could no longer ignore it as before.

"It seems that when you break through in the future, you can't do it in your own room, you have to find a solid secret room. Chu Tian groaned slightly, looking at the mess all over the ground, and couldn't help frowning.

Immediately, his eyebrows relaxed, his face showed sincere joy, and he clearly felt the change in his soul.

The spiritual cultivation of the second-level nun, he finally achieved it.
