?? The ninth floor of space inside the Tower of Trials.

Ye Tianchen's eyes were distracted, and he was completely out of focus.

And the scenery around him has no longer the original fragrance of birds and flowers, but has become a huge ruin.

The old man hidden in the darkness of the void looked at Ye Tianchen, who was obviously unconscious, and said to himself: "This last level is a test of mood, and it can be said to be the most difficult of the three levels. ”

"And there are only two results, one is to rely on the mental strength of the geocentric level, persist in the illusion for a day, and wait until the illusion is automatically lifted. ”

"The second is to die directly in the illusion!"

Mental strength is different from other powers, and it does not change much because of the ascension of the realm.

And mental strength has nothing to do with talent, many top geniuses are not too good.

The strength of mental power is divided into three stages, the first stage is the human heart, which is the mental strength possessed by ordinary human beings and martial cultivators.

The second stage is the center of the earth, and the mental power of this stage is already very powerful, which can greatly increase one's comprehension, and it is not affected by ordinary illusions or illusions.

Even, the mental power at the back level of the center of the earth can be used to attack!

And the last stage is Tianxin!

If the mental strength reaches the heart of heaven, it will be able to exert unimaginable power, and even the emperor will have to back down!

However, in the Vast Realm for several years, almost no one had cultivated their mental strength to the Dao Heavenly Heart level.

Therefore, if you want to cultivate the Dao Heavenly Heart, it will be much more difficult than becoming an emperor.

Each stage of mental strength is divided into nine layers.

Basically, the number of people who can reach the first level of the earth's center is very rare.

The old man couldn't be sure whether Ye Tianchen's mental strength had reached the center of the earth. After all, if you don't have a special chance, it is very difficult and time-consuming to want to grow.

Under normal circumstances, it is almost impossible to cultivate mental power to the geocentric level before the age of thirty.

That's why he was worried that Ye Tianchen would die because he couldn't pass the final trial.

"If his mental strength reaches the first layer of the earth's core, there is an eighty percent chance of surviving the day. The old man stared at Ye Tianchen: "If the mental strength reaches the second layer of the center of the earth, there will be no accidents." ”

As soon as he finished speaking, Ye Tianchen's body below shook suddenly, and his godless eyes returned to normal.

Seeing this scene, the old man's face was full of shock and disbelief.

The next moment, his figure flashed, and then appeared beside Ye Tianchen.

"Fang Cai's illusion is the third level of trial?" Ye Tianchen asked lightly.

"What the hell is going on?!" the old man did not answer directly, but asked rhetorically, "The illusion will obviously last for a whole day, but you are no longer affected by the illusion?"

"I've shattered the illusion. Ye Tianchen said lightly.

"Impossible!" the old man shook his head and said, "Even if your mental strength reaches the second or even third layer of the center of the earth, it is impossible to forcibly break through the illusion. ”

Ye Tianchen smiled faintly: "My mental strength has already reached the fifth layer of the center of the earth, and it is not difficult for me to break through the illusion of Fang Cai." ”

"The fifth layer of the center of the earth?"

The surprise on the old man's face was even stronger: "How is this possible...... Mental power is different from martial arts or mental power, etc., there is no way to increase instantaneously, and you can only rely on time to grow slowly. But even if a person who has lived for thousands of years and focuses on cultivating his mental strength, it is difficult to reach the fifth layer of the center of the earth. ”

He was really shocked, because he knew very well how difficult it was to improve his mental strength.

At first, he was worried that Ye Tianchen would die in the illusion because his mental strength was not strong enough.

But he didn't expect that this was the most difficult trial that he thought would become the easiest trial for Ye Tianchen.

From the time Ye Tianchen was dragged into the illusion to the time Ye Tianchen came out of the illusion, he didn't even take ten breaths.

Destroying the illusion so simply was something he couldn't have imagined.

"I was born strong. Ye Tianchen smiled slightly, although after being reborn, his mental strength and spiritual power were affected a lot.

However, his mental strength still has the fourth layer of the earth's core, and after several years of accumulation, his mental strength has also reached the fifth layer.

But if you want to use your mental strength to fight, you can at least reach the seventh layer of the center of the earth.

Therefore, usually, he did not show the strength of his mental strength at all, at most, he relied on the strength of his mental strength, so that he could get a lot of improvement when he comprehended and cultivated.

"I see, but I've heard that some demons with amazing mental talent are born with mental strength at the center of the earth. ”

The old man nodded first, and then said, "But even if this is the case, it is still unbelievable that you can raise your mental strength to the fifth layer in just over twenty years. ”

"You don't seem to have answered my question. Ye Tianchen said indifferently: "The previous illusion is the final trial?"

"That's right. The old man nodded and said, "That illusion is very dangerous, and even I can't control it. Basically, there is no other way than to rely on mental strength to fight. ”

"I've already passed the trial?" Ye Tianchen asked.

"That's true. ”

The old man said slowly: "Although under normal circumstances, you have to fight against the illusion for a whole day, and finally wait until the illusion disappears naturally. However, because the illusion has been destroyed by you, you will not be in any danger from the future, as long as the time is up and the trial will be over. ”

Ye Tianchen nodded lightly, and then asked, "What benefits can I get from passing the nine-layer trial?"

He had only heard the old man say that if he passed all the trials in the Trial Tower, he would be able to get unimaginable opportunities and benefits.

As for what the chances and benefits were, the old man only said that when the trial was over, he would naturally tell him.

"You can become a true disciple of the master. The old man said, "And you can also get a rare mental cultivation method, as well as a powerful secret technique." ”

"Mental Cultivation Method?!" Ye Tianchen had a look of surprise on his face.

Even in his previous life, he had already stood at the top of the Haohan Realm, but he still hadn't found the method of mental cultivation.

This shows how precious and rare the method of mental cultivation is.

It can be said that even if he broke through the Trial Tower this time, even if he didn't have any other gains or rewards, just obtaining the mental strength cultivation method would already be extremely worthwhile.

As for becoming a disciple of the old man's master, he didn't care too much, after all, he already had a complete idea of his cultivation path.

And the last secret technique, he also doesn't pay attention to it, because there are no less than a hundred secret techniques he has mastered.

However, because of the realm, he can't use the secret technique for the time being.

To some extent, the secret technique is an evolved version of the martial art, and only after becoming a saint and having a complete holy power in the body can the secret technique be activated and used.

Even the weakest secret technique, in terms of power and prestige alone, is far beyond the god-level martial arts.

At the same time, the difficulty and value of the cultivation of secret skills are also far above those of martial arts.

Therefore, most of the Sages still use martial arts, and only a very few Sages can perform secret techniques.

Most of the people who have mastered the secret technique are at least strong people above the Saint King.
