Xiu Tianyu was overjoyed in his heart, and it had finally arrived. He cheered up again and walked towards the flames with difficulty, the exercises worked to the extreme, forming a film of Yuan Qi in his hands, and then descended towards the flames.

"Poof......

Xiu Tianyu's hand only got a little closer, and the Yuan Qi membrane on his hand was shattered by the fire wave. Xiu Tianyu was unmoved, condensed the Yuan Qi membrane again, and continued the next action.

Failure, failure, or failure, I don't know how many times he failed, Xiu Tianyu finally succeeded, and the demonic blood-red flame was finally held in his hand.

Xiu Tianyu was overjoyed in his heart, and he didn't dare to delay at all, so he hurriedly ran the devouring method and began to refine and absorb the essence of this fire.

"Bang ......"

As soon as the exercise was running, the flames in his hands suddenly burst open and scattered in the stone hall. Xiu Tianyu was stunned, and for a while, he didn't know what to do, and the scattered flames, he couldn't start refining and devouring them at all. Fortunately, after a while, the scattered flames began to gather again, and he breathed a sigh of relief and began his next attempt.

Two full days have passed, and seeing that Xiu Tianyu has not come out yet, Mo Zai can be said to be anxious and restless at the entrance of the cave. Mo couldn't help but think in his heart, no, according to the exercises, devouring, refining, and absorbing the essence of heaven and earth shouldn't be so difficult, it can't be that something happened! Could it be that the old guy's theory is wrong?

The ink outside the stone cave was anxious, and Xiu Tianyu in the stone cave was even more anxious. No matter what he did, as long as he started to run the Devouring Refining Technique, the Pure World Heavenly Flame would burst open, he didn't know how many times he had tried, but every time it was like this. This couldn't help but make him worried, if he couldn't devour this essence, the exercises would not be able to advance, and his cultivation would also stagnate......

It may be that he has tried many times, or it may be that his mind is not calm, which makes the pure world Tianyan also angry, and the more ferocious flames continue to roll, vowing to burn all the vanity in the world.

Be calm, be calm. Looking at the flames of constant rage, Xiu Tianyu kept admonishing himself, and he forced himself to calm down again and think about countermeasures.

"Could it be that there is a mistake in the exercises, the essence of heaven and earth cannot be devoured and refined, and absorbed, so what should I do?" Xiu Tianyu frowned with difficulty, constantly thinking in his heart.

"You can't devour and refine, so what if it's assimilation?" Xiu Tianyu's heart moved, and he did it when he thought of it.

The Yuan Qi emanated from his body, enveloping the Pure World Heavenly Flame, and then he was running exercises to absorb this Yuan Qi back into his body. Under his continuous attempts, the situation finally changed, and a trace of Pure World Heavenly Flame actually fused with his vitality and was absorbed back into his body.

The flames entered the body and burned in an instant, and even the trace of spatial power on the meridian wall was instantly incinerated, and the meridians were burned with a clattering sound. Suddenly, the meridians were like the little snake that had been stimulated, and they instantly tensed, and a sharp pain that reached deep into the soul directly made Dexiu Tianyu couldn't help but spurt out a mouthful of blood.

Xiutian Yu's eyes were torn apart, his flesh and blood were burned red, such a severe pain was really unbearable, if it weren't for his physical abnormality, the first thing that would have been destroyed was his blood vessels and meridians.

Xiu Tianyu gritted his teeth, and the sudden and severe pain made Xiu Tianyu's head dizzy for a while, before it gradually subsided, and then he didn't think much about it, and hurriedly concentrated his mind again, controlling the wisp of blood-red flame, which slowly ran along the meridians.

The operation time was getting longer and longer, and Xiu Tianyu's mind became more and more proficient in the control of this wisp of flame, and he endured the pain, once again incorporated the wisps of flame into his body, controlling their circulation in the meridians and veins.

With the passage of time, this blood-red flame had been absorbed by Xiu Tianyu by as much as half, and when there were more flames in his body than in his body, something happened suddenly. The flames outside his body no longer allowed him to slowly pull away, but suddenly moved, wrapped Xiu Tianyu in it, and then took the initiative to burrow into his body, scurrying around in his body, wanting to gather with the flames he had absorbed earlier.

It is precisely because of this that the scorching heat released from the blood-red flames is becoming more and more terrifying, and now, the spatial power in the meridians of Xiutianyu's blood vessels has been shattered suddenly, and the vitality has also been defeated under the attack of the flames, and what makes him even more desperate is that the vitality in his body was actually ignited by the blood-red flames and burned wildly in his body.

Clenching his teeth, Xiu Tianyu desperately controlled the wisps of blood-red flames and prevented them from rioting in his body. The blazing temperature and monstrous waves of fire emanated from it, swept the meridians, penetrated the bones, and made Xiu Tianyu's body skin bloom a small blood-red blood bubble, the blood bubbles shattered, revealing the red flesh under the skin, and the tiny blood-red cracks spread out from the flesh like a spider's web, and finally wrapped Xiu Tianyu's whole body, except for his weird right hand, his whole person was like a humanoid doll pieced together from fragments, looking so terrifying that people dare not look at it directly.

After all the blood-colored flames entered Xiu Tianyu's body, the terrifying high temperature in the fire cave disappeared, and at this moment, Mo, who had been worried about Xiu Tianyu, couldn't help but rush in anymore.

Looking at Xiu Tianyu's shattered skin like fragments, Mo Da on the side was shocked, and his soul body trembled involuntarily. This phenomenon of skin bursting shows that Xiu Tianyu's body has been filled with blazing flames, and the way of the flames is blocked, and it can only break Xiu Tianyu's flesh and skin, and then escape with the help of these torn cracks!

The beast's face changed and changed rapidly, Mo's big mouth tightened and loosened, loosened and tightened, and after a while, Mo Fang suppressed the impulse and uneasiness in his heart, and waited quietly aside, afraid that he would not pay attention to make any noise and disturb Xiu Tianyu.

Mo's heart is also helpless, this devouring heaven and earth essence is already dangerous, and it is necessary to prepare many heavenly and earth treasures and all kinds of elixirs to assist, but in this strange Netherworld Thunder Domain, where to find any auxiliary things, everything can only depend on the ability to cultivate Tianyu!

Xiu Tianyu didn't have time to pay attention to the changes in his body, and after some hard work, he finally gathered the scattered flames together and began to flow along the meridians where the exercises were running.

The five Martial Dao Void Crystals in his heart spun wildly, exuding powerful vitality to protect his heart from being eroded and destroyed by the blood-red flames.

Xiu Tianyu struggled to mobilize the vitality in his body, constantly repairing the damaged meridians, and mobilizing the power of space to reinforce it, and the blood-colored flames were destroyed again and again, and he continued to repair and strengthen them again and again.

After destroying his body to the point of insignificance, the flames finally completed a Great Zhou Tian operation in Xiutian Yu's body, and then rushed towards his heart.

Xiu Tianyu was shocked in an instant, if he let this flame rush into his heart like this, then he would have to die here. He didn't pay attention to anything else, and tried his best to run the Martial Dao Void Crystal, mobilizing his vitality to block the flames from rushing towards his heart.

But everything is so easy, in the meridians, the fortress formed by the purple vitality is constantly burned into nothingness. And the Martial Dao Void Crystal in his heart is also rotating and transporting the vitality as if it is not fatal, how much the flame burns, it is how much it is transported, although it is spelled down like this, the vitality stored in the Martial Dao Void Crystal is decreasing at a speed visible to the naked eye, and the brilliant Martial Dao Void Crystal has also become dim, but the Pure World Heavenly Flame has gradually become docile and began to circulate smoothly in the reverse Qiankun exercise route.

After the vitality in the meridians was compatible with the flames, Xiu Tianyu finally breathed a sigh of relief, and then controlled the flames after compatibility, which slowly flowed into the heart, and then he ran the devouring technique against the universe, and in an instant, the martial arts void crystal that was rotating clockwise suddenly stopped, turned into a counterclockwise crazy rotation, and the flames were slowly absorbed by it.

When the last wisp of flame was also eaten by the five Martial Dao Void Crystals, Xiu Tianyu immediately cheered up his spirit, mobilized the Martial Dao Void Crystals in the reversal, and released wisps of strange blood-red flames, flowing towards the special meridians that evolved against the Qiankun.

Only by opening up these specific meridians can the reverse Qiankun be regarded as truly rooted in his body and completely integrated with him, and he can rely on devouring many essences to make this exercise continue to evolve and become stronger. These specific meridians are the source veins of the exercises, the origin veins of the rebellion.

These special meridians exist in every human body, but they are not ordinary meridians, but dead veins in the human body, although it is in the human body, but people can't find it, can't see it, and have no other effect. It was also after cultivating the Reverse Qiankun that Xiu Tianyu knew that in this world, there was still a dead vein in the human body.

What he had to do now was to run the flame essence to open up those dead veins and rejuvenate them. This is equivalent to reopening a new meridian in the human body, and the difficulties and dangers in it are simply prohibitive, and the pain from the depths of the soul is even more difficult to relate.

When Xiu Tianyu's endurance had reached its limit, the blood-red flame finally drilled out the last origin vein of the evolution of the Reverse Qiankun Exercises......

At that moment, it seemed that some kind of invisible barrier was quietly shattered in Xiutian Yu's body. This origin vein finally has vitality and vitality.

When the blood-red flames flowed out of the last meridian and returned to the heart, Xiu Tianyu's head, which was almost numb from the severe pain, suddenly burst into a faint warm feeling, making his vague consciousness clear a little.

At this time, the Pure World Heavenly Flame, after hovering in the Martial Dao Void Crystal for a while, then together with the Yuan Qi, shuttled through the reverse Qiankun exercise route, the high temperature that burned everything was continuously released in the flames, and slowly converged with the continuous operation of the exercises, and after a few weeks, the extremely destructive high temperature almost completely converged into the Martial Dao Void Crystal, and the rage dissipated, a little docile, faintly emanating.

"Did it work..."

In the cave, Mo looked at Xiu Tianyu who couldn't find a piece of complete skin on his body, he breathed a deep sigh of relief, his soul body was filled with gratifying warmth, nodded slightly, bent his claws and waved lightly, and a fist-sized stone on the ground turned into a gray light, and shot straight towards Xiu Tianyu, who was still sitting cross-legged.

As the stone approached, in an instant, a dazzling blood-red flame shot out from the body of the self-cultivation Tianyu, and finally wrapped him in it, instantly turning into a blood-red flame light shield, and the flames on the light mask rolled and circled, blocking everything that was unfavorable to it.

Staring at the sudden appearance of the flame cover, a meaningful smile appeared on the face of the ink beast, and he muttered in a low voice: "What a good little guy, not only can he bear the pain of burning his body with the essence of fire, but he can also find mistakes in the exercises, and he can improve the exercises by himself and break through the bottleneck, which is really amazing......"

"Old man...... You're not mistaken about us...... Really able to get out of here. ”

In the spacious stone hall, the blood-red flame cover was like a silkworm cocoon, enveloping the young man, and the churning blood flame seemed to announce that he was about to break the cocoon and turn into a butterfly......
