After the Hydra Demon disappeared, Zhou Yun's mind also retreated from the Boundary Crystal Space, and Zhou Yun did not directly believe the words of the Hydra Demon, but carefully thought about the feasibility of it.

Although the Hydra Demon is an evil beast, it has existed for hundreds of thousands of years and has long been familiar with the laws of human society.

From the time he came into contact with the Boundary Crystal World to the present, Zhou Yun had been carefully observing the state of the Hydra Demon, which was a kind of breath observation.

The only hostility of the Hydra Demon Zhou Yun could be clearly felt, and most of the time, the Hydra Demon was not so aggressive when facing him.

"If I were the Hydra Demon, there would be no need to set such a trap. From its words, I could tell that as long as I had this Boundary Crystal, I could deal with it, so even if he wanted to get rid of me from here, he would have to find a chance to kill me with one blow. Just fusing the Black Flame Crystal, even if it is really dangerous, is not fatal enough, and I believe it will not be so stupid. ”

After thinking carefully for a moment again, Zhou Yun silently spoke out in his heart.

Moreover, the Hydra Demon also specially explained to him that he could only fuse one Black Flame Crystal and strive to cultivate for a breakthrough, and the other Black Flame Crystals had to wait for the foundation to be stable before fusing in order to obtain good results, which represented a long-term plan and also dispelled some of Zhou Yun's concerns.

With a wave of his hand, suddenly, a black flame crystal was taken out of the space ring by Zhou Yun and gently held it on his hand.

Dragging the Black Flame Crystal, Zhou Yun immediately felt an extremely condensed force, very large and strong. Zhou Yun was already feeling very comfortable just bathed in the light and aura emitted by the black flame crystal.

Such a treasure, if fused, what kind of effect can it have, Zhou Yun's heart couldn't help but look forward to it.

Zhou Yun had already felt it when he fought with Luo Tian before, the strength of Luo Tian's true power was very good, and the condensation of the attack was also the best choice, and the most important thing was that after a simple fight, Zhou Yun found that Luo Tian's talent was actually not high.

This is also a little problem that Zhou Yun sees in this area, although Zhou Yun doesn't know what the situation is like in the entire Black Flame Continent, but just talking about the Northern Princes Alliance, the talent of the people here is not even as good as the people on the Tianyuan Continent.

On the Tianyuan Continent, Zhou Yun, an existence beyond the realm of Martial Saints, has only seen two in total, and the lord of a small country like Luo Tian can have such a cultivation, I am afraid it is because of the power of this Black Flame Crystal.

Thinking of this, Zhou Yun finally made up his mind.

Untied the clothes on his body, Zhou Yun took out a short sword and stabbed it violently at the position of the dantian!

Suddenly, a wound appeared in Zhou Yun's lower abdomen, and the wound appeared, and Zhou Yun immediately stuffed the black flame crystal from the wound. As soon as the Black Flame Crystal entered his body, Zhou Yun immediately felt an extremely comfortable feeling, and all the power naturally emitted by the Black Flame Crystal was directly absorbed by Zhou Yun's body, and the effect was very obvious!

Although he was pleasantly surprised, Zhou Yun did not forget what he should do, and with a wave of his hand, the boundary crystal immediately appeared in Zhou Yun's palm. Connected to the boundary crystal, Zhou Yun immediately felt that the wound in his dantian position was still healing quickly.

There was a black flame crystal in his body, and with the effect of that boundary crystal, the wound in Zhou Yun's dantian position was actually restored in a very short time!

After about a stick of incense, the wound was completely gone, and feeling that the wound in his dantian had recovered, Zhou Yun immediately adjusted his breathing and prepared for the next step.

Although the Black Flame Crystal was buried near the dantian, after all, it was not really entering the dantian, and Zhou Yun's condensation of strength in the meridians in his body was still unaffected.

His hands were slowly raised, and suddenly, a layer of true power floating light visible to the naked eye floated on Zhou Yun's body, and powerful fluctuations came, and Zhou Yun's momentum instantly increased several times!

Having already spread most of the true power in his body, leaving only a part of his true power to guard the dantian, Zhou Yun suddenly retracted his body, and the true power emanating from the edge of his body immediately concentrated, and rushed towards the black flame crystal in the dantian position!

Rumble!!

With the impact of Zhou Yun's powerful and domineering true power, the Black Flame Crystal suddenly let out a roar, and it exploded directly!

As soon as this black flame crystal opened, Zhou Yun's whole person immediately fell into an incomparably sharp pain.

In an instant, Zhou Yun's face had already turned blood-red!

The pain of this fusion is countless times greater than the pain of fusing the mixed yuan real gold before!

But now Zhou Yun's true strength and physical endurance are no longer the same as they were then.

Remembering the words of the Hydra Demon in his heart, Zhou Yun had already been mentally prepared for this kind of pain.

Suppressing the pain in his body, Zhou Yun began to meditate and feel the changes in his body. After the Black Flame Crystal exploded, a wave of power immediately began to run wildly in Zhou Yun's body.

Not only that, but at the location where the Black Flame Crystal exploded, a steady stream of power was still surging out, enriching Zhou Yun's body!

"No, if you go on like this, you will explode and there will be big damage!!"

In an instant, Zhou Yun was already aware of the crisis in front of him, and hurriedly gathered his mind, Zhou Yun began to introduce the true power flowing in his body into the meridians, and began to run rapidly.

Sitting there, Zhou Yun's face was blood-red, and he kept breathing and breathing, and a stream of power was transmitted from the location of the explosion of the Black Flame Crystal, which was introduced into the meridians by Zhou Yun, and then condensed and turned into real true power.

In this continuous transformation, Zhou Yun's originally blood-red face gradually faded. However, the crisis has not been completely resolved.

"The power in this Black Flame Crystal is really huge enough, after so much time, it is still being released!" Feeling that the place where the Black Flame Crystal was broken in the dantian position was still pouring out of power, Zhou Yun couldn't help but think in his heart.

At this moment, Zhou Yun's meridians were already full of true power, and if the Black Flame Crystal continued to be released, Zhou Yun's meridians would probably be unable to withstand it.

As if ignoring Zhou Yun's worries, where the Black Flame Crystal was shattered, a stream of power was still surging out. There was no other way, and Zhou Yun could only introduce these powers into his meridians and condense them!

Gaba!

As a large amount of true power continued to be sucked into the meridians by Zhou Yun, finally, a crisp tearing sound came out in Zhou Yun's body.

"Are the meridians broken!" Hearing this voice, Zhou Yun immediately felt a shock in his heart.

Instead, Zhou Yun immediately felt the changes in the meridians in his body, and when he held his breath and looked inward, Zhou Yun was immediately attracted by the changes in his own meridians.

"This ...... It's not the broken meridians, but the displacement of the meridians?" Feeling the changes in his body, Zhou Yun couldn't help but let out a voice in shock.

It turned out that the sound of Fang Cai's knife tearing was not a broken meridian, but a meridian in Zhou Yun's body close to the dantian that changed its original position!

Gaba!

Instead, the sound of the meridians in Zhou Yun's body becoming denser, and the meridians of the entire body began to move slowly, and the Tianyang meridian near the dantian initially moved, translating an inch in the direction of the right side of the body, and some of the original vein points that were too bent became much smoother in this shift.

Suddenly, the speed of the true power in Zhou Yun's body became even faster when it passed through that meridian!

As more and more meridians began to displace, the speed of the true power in Zhou Yun's meridians immediately became faster, and when displacement, the meridians in Zhou Yun's body were still devouring the true power running in the meridians, devouring these true forces, Zhou Yun's meridians immediately became more tenacious.

The feeling of fullness that I just felt disappeared without a trace!

The true power in his body flowed faster and faster, and even caused a positive change in Zhou Yun's whole body.

Small black spots were actually pulled out of Zhou Yun's bones, bringing a refreshing feeling.

Sensing this change, Zhou Yun immediately concentrated on it, but found that his bone marrow was actually transformed in a pure direction under this change!

Meridian displacement, bone marrow purification!

At this moment, Zhou Yun really understands what kind of changes he is experiencing!

"Easy tendon to wash the marrow! This is the real easy tendon to wash the marrow!" Feeling the growth of his body, Zhou Yun's face couldn't help but float with a burst of ecstasy.

His body was changing little by little, and Zhou Yun could even clearly feel the growth of his strength in this kind of change!

Bone marrow purification will bring a more flexible body, although Zhou Yun did not move, but he has already felt that his body is much lighter and faster, if you use pneumatic steps, I believe that the effect of movement will be more than twice as good as before!

Moreover, this kind of lightness does not affect Zhou Yun's use of the majestic and heavy ** such as the Overlord Step! Because although it is dexterous, Zhou Yun's body is not at all calm!

The displacement of the meridians completely straightened out the unreasonable arrangement of the meridians in the original body, just like channeling the river and regulating the traffic, and the flow of true power in Zhou Yun's body became smoother. After passing through the displacement of the meridians, Zhou Yun was several times faster than before.

Not only that, due to the fast speed of true power running in the body, when Zhou Yun was running Zhou Tian, the speed of a Zhou Tian would be half less than before, which would directly lead to Zhou Yun's cultivation speed becoming faster in the future!

Finally, as the transformation on Zhou Yun's body was completely completed, the place where the Black Flame Crystal was shattered exuded a burst of true power, and finally returned to calm!

Feeling the abundant strength in his body, his agile body, and his tenacious meridians, Zhou Yun found that with his body's current capacity, even if he was absorbing a few Black Flame Crystals, it would be no problem!

But thinking of the words of the Hydra Demon, Zhou Yun quietly dispelled this thought.

Following the guidance of the Hydra Demon, Zhou Yun's fusion this time has already benefited a lot, which also proves that the Hydra Demon really wants to guide him, there is such a person who has existed for hundreds of thousands of years, as the mentor of the Eight Ancient Beasts, Zhou Yun is stumped to make good use of it?

Since the Hydra Demon advised him to absorb only one, then he would definitely be as good as he was.

"Xiu Wei has finally broken through to the realm of Martial Saints, I didn't expect the process to be so fast, it's time to find trouble with Na Luo Tian. Feeling the power in his body, Zhou Yun clenched his fists, and an indifferent smile appeared on his face.
