The transformation of Yuan Qi into True Yuan is not just as simple as the realization of Yuan Qi into a liquefied state.

After the vitality is completely transformed into a liquid state, the first wisp of true essence will be born, and then after a long period of warmth, this wisp of true essence will continue to grow, and finally all liquid vitality will have its own glow vision, which is the sign of true yuan all over the body.

After Bi Yu absorbed the juice of the fourth alien snake vine, the first wisp of true essence in his body was born.

This wisp of true essence exists in the long river of liquid vitality, like the brightest star in the galaxy, dazzling.

There are two in one, three in evolution, and then thousands and thousands.

After the birth of this first wisp of true yuan, if nothing else, Bi Yu will continue to warm up on his own, and it will probably take several years to make all the liquid vitality in his whole body turn into true yuan.

But with the effect of the alien snake vine, this process has undoubtedly been shortened a lot.

The long river of vitality in his body circulates through the Zhou Tian according to the route of the Doomsday Heart Sutra, and after almost every week, a large amount of white juice will be absorbed, which will cause more and more liquid vitality to produce glow.

It's just that soon, when all the white juice has been absorbed, the speed of true element derivation suddenly slows down.

Bi Yu was slightly disappointed, but he quickly gathered his mind, sensed carefully for a while, slowly closed his work with satisfaction, and opened his eyes.

In his body, almost one percent of the liquid vitality was now all over the glow, and it had been successfully transformed into true yuan.

With this true element, it will slowly grow and grow, and the remaining ninety percent of the liquid vitality will also be driven to slowly derive into the true element.

Raising his arm, Bi Yu stretched out his index finger. In an instant, a wisp of true yuan condensed from the fingertips, forming a gray light sword qi.

This sword aura condensed but did not emit. Spouting sword rays at his fingertips, a trace of true yuan surged.

Although the sword qi is gray. But it seems to flow with glow, dense like mist, introverted, revealing a tenacity, a kind of sharpness.

If his previous Yuan Qi had not yet given birth to the True Yuan, its texture was wood, then now, when all his Yuan Qi was liquefied, the True Yuan was born. This texture has taken a huge leap forward, and it has become like steel.

"The power of the true element is infinitely mysterious, and if this true element is mixed with it when the Heavenly One Formula is cast, it is like when the iron sword is refined, it is mixed with a piece of Gengjin, which immediately makes the edge of the iron sword more vigorous, and the lethality is greatly increased.

And if my body is completely filled with true elements. Between one move and one style, it is all pure True Yuan explosion, then it is like holding a divine weapon that is completely refined by Gengjin Xuantie, who can stop it?"

I thought about it for a moment. Bi Yu suddenly pointed out, and the gray light sword qi between his index fingers shot out, as if it was formless and substantial. Although the speed was fast, there was no sound of breaking wind.

If you slow down a hundredfold to see. It can be clearly seen, before this gray light sword qi. The air was trembling and chaotic, forming a vacuum, slamming into the rock walls of the cave.

Without the slightest sound, this gray light sword qi entered directly into the rock wall, and there was a faint wave of destructive power, and an unfathomable hole appeared in the rock wall at first, but after a breath or two, the small hole spread silently and turned into a deep pit.

Cracked rock walls fell, and the rock wall structures in the pit were all shattered, like a large number of pinholes.

Bi Yu's eyes froze, and he was even more excited when he was surprised, and when he raised his hand, another sword qi condensed at his fingertips.

But this sword qi, compared to the previous one, obviously did not have any true yuan incorporated, it was purely condensed by the last qi qi, and there was no glow flow in it.

The moment he pointed out, the gray light sword qi that was not mixed with the true yuan burst out, bringing a slight air-breaking sound and slamming fiercely on the other side of the rock wall in front of him.

With a pop, the sand and stones splashed, and the gray light sword qi pierced directly into the rock wall and dissipated.

Bi Yu fixed his eyes on it, but saw that an irregular crater appeared on the surface of the rock wall, and no matter the depth or the degree of destruction, it could not be compared to the previous sword qi mixed with true yuan.

"The power of the sword qi condensed by driving the sword technique with the true yuan is more than ten times more than the condensation of the yuan qi."

Looking at the rock wall that was half a zhang deep, shattered to the point of being almost slag, and then looked at the uneven potholes that were only a dozen centimeters deep, Bi Yu made an accurate judgment.

This place of the dead is shrouded in a thick fog of dead air all year round, which makes the earth, mountains, rivers, soil and rock walls extremely tough.

The soil may be a little soft due to the fog because of the accumulation of water in the soil, but in terms of hardness, it is more than in most other areas.

Bi Yu's current strength can penetrate a half-meter-thick iron plate with a single sword qi in his hand, but in this Cave of the Dead, ordinary rock walls are harder than iron plates, and they are not so easy to destroy.

Trying to enter the state of self-forgetfulness, Bi Yu felt the world of heaven and earth around him projecting in his heart.

He felt the water in the soil, which was a dead gas and fog that had accumulated after it had become so dense that a drop of water would be a deadly poison if given to the living.

"If the water sword is destroyed, I am afraid it will be a little difficult to condense one again in my current state, but the water condensed by the death qi here is extremely terrifying, if I can reunite the water sword with this water, I will have one more killing move.

And I have stepped into the Qi madness, and the seventh form of the Doomsday Sword Technique should also be able to be displayed. ”

Slowly getting up, Bi Yu withdrew from his selfless state of mind, and looked at Jiang Shan with indiscriminate eyes.

The other party was still sitting cross-legged at this time, and the long black cloak, lining his tall back, looked full of momentum.

On Jiang Shan's body, there were some fireflies, and the light emitted by the juice of these bright golden grass was not as bright as it was at the beginning, and it had obviously been absorbed by the other party a lot.

In the burly bone frame, most of the cracks between some bones have healed, and even some of the blood tendons that were previously broken connecting bones have also healed again at this time.

The strength has reached the point of the other party, and with a rare spirit grass like Ming Jin Cao, even if it is seriously injured, the recovery is extremely fast.

"In half a day, it's time for us to go. ”

As if sensing Bi Yu's gaze, Jiang Shan's eyes flashed with milky white flames, and he reminded him in a deep voice.

He already felt that Bi Yu's strength had improved, but this increase was not enough to move him.

"Time flies so fast"

Bi Yu sighed, nodded, and turned around and walked to the other side of the cave, trying not to disturb the other party.

There is still half a day to go, and he wants to try whether he can re-condense the Ruoshui Sword with his selfless state of mind and control of the surrounding environment.

If you want to say that the previous Ruoshui Sword, he was also condensed purely by chance, luck accounted for most of it, and it was extremely difficult to replicate the experience of the last time again.

But now that he has the True Yuan in his body, the ability of this condensation should also be improved a lot, which is also where his confidence lies in wanting to reunite Ruoshui Sword. (To be continued.) )
