The old man shook his head helplessly and said, "Everything in the world has positive and negative, yin and yang. This is what we often say, the extreme of things must be opposed. Although it is all dead here, if there is enough dead air, it may not be impossible to live, so you can go!"

This time, the old man didn't say any nonsense to Ye Yun, and the gray mist in the sky rolled up, rolling Ye Yun high. Suddenly Ye Yun felt dizzy, even if he had respect for the old man, he couldn't help but slander in his heart, "Is there a mistake, come ...... again"

This time, it was the first time that Ye Yun was forced to fly in the sky without the help of a Taoist weapon after Ye Yun became a Taoist master. It is also unforgettable for a lifetime, the feeling of flying. If it weren't for his physical strength, I'm afraid he wouldn't be able to withstand such a toss.

When Ye Yun opened his eyes, he was stunned, because there was a pool of water in front of him with a radius of dozens of zhang. However, the water in this pool is extremely strange, and it is actually turbid.

"What are you doing in a daze? This is the Yin-Yang Pond, if you go forward along this lake, it will be the Yin-Yang Spring. The old man asked you to come here precisely to use the power of the water of the Yin and Yang Pond to wash your muscles and marrow again. Yin and Yang Tian is the first pool that opened the world, and it is also formed by the convergence of the first spring water that opened the world. Every cultivator only has one chance in his life to wash his muscles and marrow, so take advantage of it!"

Ye Yun was overjoyed when he heard this, as long as he could improve his strength now, he wouldn't care about anything. His eyes were shining, staring closely at the Yin and Yang Pool, and with a "poof", he jumped up and fell into the water.

Yin Yang Pond is extremely weird, according to common sense, Ye Yun jumped into the pool like a big stone, and it should splash. But the Yin Yang Pool seemed to be illusory, and Ye Yun fell heavily into it, without any reaction at all.

Ye Yun, who was still excited, was stunned for a moment, and before he had time to think about the reason, he suddenly felt a strange cold surging towards his body.

Ye Yun only felt a tremor all over his body, and the water of the Yin Yang Pool actually followed his pores, penetrating everywhere, constantly burrowing into Ye Yun's body. His body was faintly visible on the edge of the pores, and there were ice crystals on the hairs of his hair.

The water of Yinyang Lake is not as cold as ice cubes, so it will not freeze Ye Yun into ice cubes in an instant. This kind of cold, just like Ye Yun's blood, actually follows every inch of Ye Yun's meridians, flesh, muscles, and bones, constantly penetrating, and penetrates everywhere.

"It's so cold...... Ye Yun trembled, and couldn't help but want to climb to the shore from the Yin and Yang Pool. However, he found that he didn't know why, he would be trapped in it, and there was no way to move at all, and he was bound by this yin and yang pool.

The old face composed of gray mist in the sky was stunned for a moment, and even the gray mist at the corner of the extremely humane mouth twitched, and he muttered to himself: "Is there a mistake? A child is a child, and when you have play, you forget the pain." Before the old man finished speaking, he jumped down like a ghost in a hurry. ”

The old man's muttering Ye Yun naturally couldn't hear it, but the old man then said to Ye Yun: "Boy, look at you, this is all yours anyway, what do you say you are anxious about! Fortunately, you have experienced the Soul Enlightenment and cultivated the Nine Turns of the Martial Pole, otherwise the Yin and Yang Water will definitely turn you into a puddle of stinky water!"

Although the old man's words made Ye Yun's heart tremble for a while, but now he no longer had any chance to answer the old man, the yin and yang water was like a maggot on the tarsal bone, cleaning up Ye Yun's whole body inside and out over and over again.

The washing of Ye Yun's body by yin and yang water constantly brought out black impurities. It's just that this pain like scraping bones makes Ye Yun can't help but look up to the sky and roar!

After a cup of tea, the yin and yang water suddenly turned, as if it had become boiling water in an instant, and it actually brought a trace of heat, which swept wildly in Ye Yun's body. The cold and biting bones brought by the yin and yang water in the body suddenly turned around, and it became like a furnace again. The whole person suddenly felt that all his internal organs were burning.

"Sneer......" Ye Yun could even hear the sound of impurities burning in his body, and his internal organs were also burned by the yin and yang water.

"Roar!" Ye Yun let out a roar like a beast, his body kept trembling, trying to break free from the shackles of yin and yang water. However, it was easy to jump off and climb ashore. Ye Yun now has no excitement to jump down at all.

The old man who had been watching Ye Yun in the sky couldn't cry or laugh, and muttered: "Ye Yun, Ye Yun, you kid is the host chosen by Tianxin, don't let me down......"

It wasn't until this moment that Ye Yun finally knew what the two heavens of ice and fire were, what life was worse than death, and why this place was called Yin Yang Pond.

Every quarter of an hour, his [Yin] water and Yang water would take turns in battle, constantly refining his physical body. The place where he stood had already been submerged by the lake, and his body was shrouded in white mist in an instant.

A trace of dirty black smoke visible to the naked eye continued to rise from Ye Yun's body, diffused in the Yin and Yang Pool, and gradually dissipated.

The indescribable sore spot spread like a tide throughout Ye Yun's body. At first, he was still roaring angrily, but then he thought that there was another person watching from the top of his head, and the ruthlessness in his heart also expanded at the same time.

The old man in the sky looked at Ye Yun quietly, in fact, Ye Yun's performance had already made him quite satisfied, but for becoming the host of Tianxin, these were far from enough. "This kid must hold on. How can the Hongmeng Dao Body be wasted, this is just the beginning, the old man wants to completely stimulate the potential of the Hongmeng Dao Body!"

Just when Ye Yun's body was constantly producing a mist of water, Ye Yun's body suddenly burst out with purple-golden light, which immediately made Ye Yun stunned, and he suddenly understood in his heart that this purple-golden light was the medicinal power of the Nine-Leaf Purple Golden Su that remained and was hidden in his body.

These medicinal powers were actually revealed in Ye Yun's physical body being continuously refined, to be precise, they were smelted. After Ye Yun's physical body was replenished by this medicinal power, the damage he had originally suffered was also repaired in the first time.

It's just that before Ye Yun had time to be happy, he couldn't help but let out a miserable scream, and the yin and yang water exhausted Ye Yun's body, and the strength of the body was refined, and it seemed to become more frequent and painful.

"This is ...... want to play to death" This is the only thought in Ye Yun's mind now.

Ye Yun tried hard to calm down, but he was actually going to silently run the martial arts nine turns in his body. According to what the old man said, only those who have undergone soul enlightenment and cultivated the Nine Turns of Martial Pole can be qualified to enter the Yin Yang Pool to refine their physical bodies, so how could he give up such a good opportunity!

Fortunately, he closed his eyes and carefully comprehended every part of his body where the yin and yang water tempered his body. When he began to run the Nine Revolutions of Martial Pole, what he didn't expect was that in the Yin Yang Water, the cold and scorching breath began to strengthen Ye Yun's muscles and flesh.
