Seeing that He Lao disappeared into the space, Xu Feng's gaze also turned to the pool in front of him. The dark and gloomy pool exuded a palpitating breath, like a fierce beast, trying to devour all of them.

Xu Feng dropped a branch again, watching the branch turn into powder and disappear in an instant, Xu Feng exhaled lightly, and felt a little apprehensive in his heart. Can a mortal body withstand such power?

"He Lao, I'll give you a new hand! Don't make a mistake in your calculations!" Xu Feng muttered in his heart, gritting his teeth and covering the purple thunder all over his body, the Dao Xuan Sutra also ran wildly in his body. The rolling aura wrapped Xu Feng, Xu Feng rose into the air, jumped up, and jumped into the pool.

Xu Feng, who was not in the pool, instantly felt a huge pressure towards Xu Feng suppressed, and the Nine Hells Water weighed tens of millions of catties, squeezing towards himself who fell into him, like a mountain suppressing it.

This tremendous squeezing force wanted to crush Xu Feng, and Xu Feng used the strength of his whole body, thunder and lightning flashed, resisting this force.

At the same time, the evil qi in it was fierce, the power of yin and evil was like a knife cutting his body, and the cold breath spread all over Xu Feng's entire body, and at the same time, a stream of dark air rushed into Xu Feng's body, and Xu Feng's body was like pouring mercury, extremely heavy.

At this time, Xu Feng was as if he had endured thousands of tortures, and all kinds of power were rushing towards him. But Xu Feng did not forget the words of Jì He Lao, and the seal knot in his hand was knotted with difficulty, and the Dao Xuan Sutra ran wildly. Between the operation of the Dao Xuan Sutra, the dark air flow that poured into Xu Feng's body was also absorbed by Xu Feng and submerged into the dantian.

After the dark air flow submerged into the dantian, Xu Feng felt that his whole person was going to be frozen, and the cold aura spread throughout his entire soul, and thick goosebumps surged up on his body.

It's just that after the dark air flow entered, the Dao Xuan Sutra began to refine this air flow. Although the Nine Hells Water is strong, the Dao Xuan Sutra is also a treasure in China, and under the refining of the Dao Xuan Sutra, the incoming air flow is also refined into a force that is integrated into the dantian, and then turns into a stream of spiritual energy flowing into Xu Feng's body.

This power was integrated into Xu Feng's body, and Xu Feng felt that his body was being beaten by thousands of hammerheads, and his body was constantly being tempered, as if making steel. At the same time, on Xu Feng's skin, runes appeared, these runes were simple and cumbersome, outlined on Xu Feng's body like tattoos, and at the same time flashed with palpitating black light. These black 'color' lights appeared, and the Nine Hellwater continued to merge into the runes, and Xu Feng's body suddenly became extremely black.

Streams of Nine Hells poured into Xu Feng's body, and Xu Feng could feel that his body became heavier and heavier. Gradually, the weight of a mountain peak was comparable, and even he couldn't lift his hands and feet.

This scene made Xu Feng a little flustered, but at this time, his body was not under his control, and the Nine Hells Water flowed into Xu Feng's body independently, turning into a stream of magical power and submerging into Xu Feng's body, the runes on Xu Feng's body became clearer and clearer, and the dark black light became brighter and brighter.

Strands of power pierced and "interspersed" in Xu Feng's body, and between the "interspersed" Xu Feng's flesh constantly had impurities coming out, and there were dirty sticky things on his body, and then they were washed away by the pool water, and they were washed clean again.

Xu Feng could feel that the strength of his physical body was increasing significantly. At the same time as the increase, Xu Feng also noticed that there were more and more runes appearing on his body, and they were becoming more and more mysterious.

"Heaven and Earth Rune Seal!"

When these runes were connected together, Xu Feng was shocked in his heart, and looked at the runes emerging on his body in a daze, these runes seemed to be able to penetrate heaven and earth, with the power of heaven and earth, Xu Feng could faintly feel that he was in harmony with heaven and earth through these runes.

This feeling made Xu Feng instantly understand what kind of talisman appeared on his body. This is a talisman raised by nature, representing the power of heaven and the law of heaven!

Using the Heaven and Earth Talisman to temper his body, Xu Feng suddenly felt a little dizzy, isn't this too terrifying?

It's not that no one cultivates the Heaven and Earth Runes to refine the body, but that is generally a strong talent after reaching great power. But he is the overlord at this time, and at this time, he sketches the heaven and earth talisman on his body, and I am afraid that no one can believe it.

Xu Feng carefully examined the runes on his body and found that there was only one heaven and earth rune seal that appeared. For this result, Xu Feng was not surprised. The more heaven and earth runes, the stronger the Xuan body. Legend has it that in ancient times, it was necessary to have at least 108,000 heaven and earth runes to be successfully refined. And the great body of the powerful person generally needs ninety-nine Dao to be refined!

Presumably these people, Xu Feng is far behind. But what strength does Xu Feng have? If he can practice one at this time, it means that he has taken the first step in refining the Ancient Xuan Body. In the future, he will be able to cultivate his physical body independently, and he will condense the heaven and earth talismans.

Ordinary people, if they want to take the first step, they must reach great power before they can get out. At this time, it means that he has the same starting point as the mighty, which is unimaginable to everyone. In the same way, one's own flesh will be unimaginably strong.

At this time, Xu Feng could feel that under the tempering of these Nine Hells Water, his flesh was refined to be extremely pure, condensed like a steel plate, weighing as much as tens of millions of catties!

The Nine Shades Hell Water continued to pour into Xu Feng's body, and the first Heaven and Earth Rune Seal gradually became complete under the influx of the Nine Shadows Hell Water, and the second Heaven and Earth Rune Seal began to condense around it.

Xu Feng hesitated for a moment, and with the power that the first Heaven and Earth Rune Seal's physical body could explode, he felt that he could knock down a mountain peak with one punch. And after the second heaven and earth talisman was condensed, Xu Feng felt that his physical body had undergone earth-shaking changes, and at this time, he didn't think it was a problem to fight against an overlord just by relying on the strength of his physical body.

"Heaven and Earth Runes are so terrifying, isn't that powerful person able to sweep under the power with his physical body?" Xu Feng thought to himself, the two realms are so strong, the ninety-nine realms are condensed together, how strong is the physical body?

However, Xu Feng didn't know that the ninety-nine Dao was the number of powerful beings. It would be good for an ordinary powerful person to be able to practice ten or eight ways. There are even some who can't be practiced at all, and their Xuantian refining is using other methods, and it doesn't have to be the heaven and earth talisman quenching. It's just that the Heaven and Earth Rune Seal is the strongest.

Therefore, at this time, Xu Feng's physical strength was a few points stronger than that of some extremely weak and powerful people.

Under the tempering of the Nine Hells Water, the third rune seal began to gradually appear on Xu Feng's body, and one rune after another pierced in the middle of Xu Feng's body, Xu Feng was like a monster carved with strange things at this time, his whole body was pitch black, the runes were shining, and he was like an Arhat's real body.

The Nine Hells Water still continued to impact Xu Feng's body, just as He Lao said, although it made Xu Feng unbearable pain. However, it did not threaten his life, under the impact of this ** pool water, Xu Feng's three heaven and earth runes began to be gradually connected. Xu Feng's body was shining with black light, and his body was like being coated with a layer of black paint, which was very strong. Xu Feng's body was like refined steel at this time.

Although he was still in the Nine Hells Water, Xu Feng could feel the terrifying power bred in his body. With this power that has nowhere to vent, Xu Feng feels that he can directly smash the overlord with his fists.

The mysterious runes on Xu Feng's body were still shining, and the Nine Hells Water had continuously impacted Xu Feng's body. What surprised Xu Feng was that the purple thunder would also devour the power in it, but the amount of it devoured was very small.

Similarly, the dantian was also incorporated with the power of the Nine Shadows Hell Water, and Xu Feng's breath began to rise slowly.

Xu Feng didn't know how long he had been soaking in it, he only knew that there was no longer that kind of pain later, but he had a habit of this sharp and cold feeling, which was extremely comfortable in it, and the Nine Hells Water had been constantly refining Xu Feng's body.

However, the fourth heaven and earth rune seal is much more difficult than imagined. No matter how much Nine Hells Water was absorbed, there was no fourth heaven and earth rune seal.

Xu Feng knew in his heart that he would not be able to refine it by relying on these diluted Nine Hells Water. Three is already the limit!

The more you get to the heaven and earth rune seal of the quenching body, the more difficult it is to appear, and the more you get to it, the more complex the heaven and earth rune seal to outline, and the greater the strength and power, which is not so easy to exercise.

Thinking that Dacheng's ancient mystic body required 108,000 heaven and earth rune seals, Xu Feng couldn't help but be speechless, thinking of that level, how mysterious and mysterious the heaven and earth rune seal was, and what kind of power it had? I'm afraid that as soon as it appears, heaven and earth will change color for it.

Xu Feng couldn't help but think of the Huaxia corpse in his ring, and he didn't know if his physical body had reached the point of Dacheng's ancient Xuan body.

Xu Feng exhaled lightly, knowing that he couldn't refine the fourth heaven and earth rune seal, and he didn't force it. He began to improve his strength with the help of his extremely strong body.

It's just that the effect of refining the body of these Nine Hell Water is amazing. However, the improvement of strength is much inferior, and the speed of improvement is far less than that of refining the flesh.

Xu Feng didn't know that the Nine Shadows Hell Water was originally a holy object for quenching the body, and it had the ability to wash the marrow and cut the bones. In the sound of quenching, there are very few that can be compared to it. If it weren't for the diluted Nine Hells Water, Xu Feng would not have been able to withstand its tempering.

Time passed little by little, and the refining effect after that was not as good as before. Xu Feng also knew that the tempering had reached the extreme at this time. At this time, his strength had already broken through the middle level, stepped into the high level, and was rushing towards the peak.

With Xu Feng's body at this time, it was not too difficult to sprint to the top. Therefore, Xu Feng worked hard, ran the Dao Xuan Sutra, and went straight to the peak.
