Three days later, Gu Yuntian sat up, his face looking better.

For the past three days, the guards came in to check on him, and when they saw that he was able to sit up, they took him out again.

Still wearing a hood, after taking off the hood, Gu Yuntian found himself in another place, which was a quiet room for practicing martial arts, and there was a sturdy young man waiting for him inside.

As soon as Gu Yuntian came in, the young man gave him a jade slip and said, "Cultivate according to the mantra described in the jade slip, if you don't understand it, you can ask me." ”

Gu Yuntian took the jade slip and poured his divine sense into it, and inside was a cultivation exercise, although it did not have a name, it must be an exercise for cultivating the power of destruction.

He looked at it, and felt strange in his heart, this was a body refining method, just read it through it in general, and he almost mastered it, because this method was somewhat similar to his family's god and demon immortal body, and some of the subtleties in it were still superior, and it seemed to be more advanced than the god and demon immortal body, but there was no mention of the word destructive power.

He didn't dare to be careless, and read through it several times, remembering the contents firmly before withdrawing his divine consciousness.

The young man asked lightly, "Have you ever learned?"

Gu Yuntian said: "It's just a half-understanding. ”

The young man asked, "What do you not understand?"

Gu Yuntian thought about it, and put forward several aspects that were quite different from the immortal bodies of gods and demons.

The young man's eyes immediately widened, because what Gu Yuntian asked was the most critical place in this body refining method. Being able to ask these questions shows that he has already entered the hall for this exercise, and there is no problem with his successful cultivation.

He thought that it would take at least three or five months for Gu Yuntian to ask a few of these questions, but he didn't expect Gu Yuntian to raise these doubts as soon as he came up.

The young man was surprised, and patiently explained to Gu Yuntian, in fact, the young man dialed it a little, and in a few words, Gu Yuntian understood what was going on, because with reference to the immortal body of gods and demons and his own experience over the years, he actually had vague answers to these questions, even if no one explained them to him, he would naturally comprehend after cultivating for a while, and now that someone pointed out, it was equivalent to taking fewer detours, so why not do it.

After the explanation, the young man let Gu Yuntian test it, and when he saw that he had already started, he asked people to take him back to the cell, and he went back to his life with a shocked face.

After Gu Yuntian returned to the cell, he practiced for four or five days, and was taken to the same cultivation meditation room, this time there was an old man waiting in the room, and after asking him a few words about his cultivation status, he nodded, gave him a black spar, and said, "According to the spiritual qi operation method taught to you, absorb the energy in the spar into your body to cultivate." ”

Gu Yuntian took the spar and sensed that there was a faint force in it, which felt very strange, weak only because the amount contained in the spar was extremely small and almost imperceptible, but there was a vague sense of indescribable fear, as if this power was about to explode and destroy everything if it could not be controlled.

This feeling was extremely similar to the feeling on the big man who interrogated him, and he immediately understood that this was the power of destruction, the strange power of the master's cultivation in this castle, and the purpose of his cultivation was to cultivate with his own body, and then take it away after he was strong.

Through that body refining technique and the action of giving the spar now, Gu Yuntian had fully understood the intentions of these people, this kind of destructive power is not something that everyone can cultivate, only by refining the body to a certain level can it withstand this terrifying explosiveness, otherwise it will definitely be destroyed by this power. And there must not be many people in the castle who meet this kind of cultivation requirements, and the progress of cultivation is slow, so the castle master has come up with such an evil method, to capture the immortals who are successful and strong in the body, and give them the cultivation method of the power of destruction, and wait until a certain degree of cultivation has achieved a certain degree of power of destruction, and then use special methods to extract these powers for their own use.

Although he already knew that his role was to make a wedding dress for the castle master, Gu Yuntian still couldn't suppress the urge to cultivate, and wanted to try out what was so strange about this destructive power. And only by understanding what the power of destruction is all about, can it be possible to come up with a solution, break this cage, and escape.

Therefore, without hesitation, Gu Yuntian sucked a trace of destructive power from the black spar into his body and ran it according to the exercises.

After the aura had been running in his body for several weeks, the old man interrupted him, told him to practice diligently every day, and not to slack off, and then called for someone to send him back.

As soon as he entered the cell, Gu Yuntian couldn't wait to cultivate. Seeing him meditating with his eyes and nose and nose and heart engrossed, Tie Niu let out a long sigh and said, "Brother, after you taste the taste of being drained of the power of destruction, you will no longer have this cultivation energy!"

The burly man and the short man looked at Gu Yuntian, although they were still speechless, there was mockery and sadness in their eyes. Gu Yuntian's appearance reminded them of themselves, when they first cultivated the power of destruction, they couldn't wait so much, how could they not resist the temptation brought by this magical power. But now they have long been numb to everything, if it weren't for the fact that a few fresh blood like Gu Yuntian would be sent after a period of time, I'm afraid they wouldn't even have the idea of living.

Gu Yuntian couldn't feel their feelings, his mind was completely immersed in the cultivation of the power of destruction. This trace comes from the destructive power in the black spar, and the color is also black, which at first glance looks like an earth aura, but when you suck it into your body, you will find that it is completely different from the earth aura.

I don't know how long I have been cultivating, and I feel that this destructive power seems to have grown a little, Gu Yuntian woke up from his state of concentration, and secretly thought that this destructive power seemed to be extremely powerful, but it was difficult to cultivate, and the progress was slow, maybe it was precisely because of this that the castle master would take such vicious means to kill the immortals to improve himself.

He suddenly thought that since the power of destruction was black, could it be related to the earth spirit qi, and as soon as he thought of this, he couldn't care about fatigue, and began to cultivate his earth spirit root again. Of course, this kind of cultivation is extremely familiar, and the earth aura runs fast in the body, and without thinking, it almost runs autonomously by instinct. After running for a while, Gu Yuntian suddenly felt that something was wrong, and now the aura is running, although it will not improve immediately, but it will always make progress, but this time the earth aura has been running for a long time, and it feels that not only has it not improved, but it has dropped a little.

He hurriedly sank his mind into his body, checked the operation of the aura in the meridians, and found that the earth aura had indeed been slightly depleted. He was stunned and confused, and suddenly thought that Fang had just cultivated the power of destruction, could it have something to do with it?

When he hurriedly checked the power of destruction, Gu Yuntian couldn't help but wonder if his divine sense was wrong, the power of destruction had actually increased compared to just now!

Then he thought, could this destructive power be able to fuse the earth aura?

So he slowed down the speed of the operation of the earth aura, carefully observed the changes between the earth aura and the power of destruction, and sure enough, he found that as soon as the earth aura was running, there was a trace of it integrated into the power of destruction, and if it stopped running, the power of destruction would not be replenished.

This discovery made him very confused, could it be said that if you cultivate the power of destruction, you can't cultivate the aura, and the aura will be absorbed by the power of destruction sooner or later?

This is also incredible, and no one told him that this will happen, the castle master undoubtedly hopes that they can all cultivate enough destructive power soon, and they should be informed in advance of possible problems, so as not to take a detour in the cultivation process.

He continued to cultivate the earth aura with the spirit of not believing in evil, turning faster and faster, and finally found that although the earth aura was constantly replenishing and strengthening the power of destruction in the process of operation, this supplement was passive, not that the earth aura actively integrated into the power of destruction, and with the extension of the cultivation time, the momentum of the growth of the earth aura gradually increased, and finally exceeded the degree of loss of the power of integration, and the earth aura began to improve overall.

This discovery lifted Gu Yuntian's spirits, and it turned out that the power of destruction could absorb the earth aura.

But why didn't the castle owner tell himself?

Gu Yuntian cultivated the earth aura for a while, and suddenly thought that it was only because the color was the same that he moved the idea of observing the difference between the power of destruction and the earth aura, and found that the power of destruction could absorb the earth aura, but this was actually not necessarily related, did the nature of the aura have anything to do with its color?

What about other aura?

As soon as his mind moved, he immediately began to operate the Wood Spirit Root.

It is said that if the power of destruction can absorb the earth aura, it will repel the wood aura. However, as soon as the wood aura was running, Gu Yuntian found that this was not the case at all, there was also a trace of wood aura integrated into the power of destruction, and the wood aura did not increase, but declined.

Gu Yuntian was excited by his discovery, and hurriedly put the fire spirit root, water spirit root, and golden spirit root into operation in turn, and found that the power of destruction was all received, no matter what spiritual energy was running, there would be a trace of integration into the power of destruction.

Suddenly, he understood, in fact, when he saw Tie Niu and the other three, he already faintly felt that something was wrong, but he couldn't say what was wrong. At this time, it suddenly dawned on me that cultivating the power of destruction does not need to divide the spiritual root, any kind of spiritual root can be cultivated, and any kind of spiritual energy destructive power can be absorbed!

He felt that something was wrong, that is, the spiritual root attributes of the three Iron Bulls were not the same, and it was said that if you practiced a specific exercise, you should use the same spiritual root attribute to be right. And of course the castle owner knew about this situation, and the reason why he didn't tell him was because it didn't matter what kind of physique he was or what exercises he practiced, as long as the power of destruction was formed in his body, no matter what exercises he practiced, the power of destruction would gradually grow.
