The soil contains the purest and purest earth's 'nature' vitality between heaven and earth, and using the soil to perceive one of the changes in the path of 'yin' and yang will get twice the result with half the effort! In the same way, using the sweet spring of life to perceive another change in the path of 'yin' and yang is also the same.

"What is the so-called nine deaths and one life...... Ye Feng said to himself, the stone tablet said that only those who die nine times can be created, but he is not in any danger at all now, and he is puzzled.

Could it be that this crisis ...... In the midst of the resting soil and the sweet spring of life, Ye Feng's heart moved.

"Even if there is a problem with the rest of the soil and the sweet spring of life, I have to give it a try, since I have come here, I can't leave empty-handed......"

Ye Feng sacrificed his wooden sword, and slashed on the ground with a sword, and with a loud bang, the ground tore open a crack, Ye Feng jumped into it, sat down, and ran to devour the Dao Species, devouring the soil in the earth.

The pure earthy 'sexual' vitality flowed into his body, flowing into his limbs and bones, making him feel as if he was bathed in a sea of earth-based 'sexual' vitality. He began to realize the Tao – one of the changes in the path of 'yin' and yang!

I don't know how long it took, Ye Feng muttered to himself: "The soil is heavy, and the other four lines can also carry ......."

After another moment, he said to himself again: "Trees are born in the earth, human beings grow in the earth, mountains and rivers stand in the earth, and rivers and seas accumulate on the earth...... Soil is the mother of all things!"

The soil is worthy of being the treasure of the world, even if the earth only contains a part of the soil, it also contains an amazing earth's 'nature' vitality! Therefore, Ye Feng was able to understand the special 'nature' of the soil in such a short period of time.

"Why is there a soil ...... in the world" Ye Feng suddenly muttered to himself, and he had doubts in his heart again.

No one could answer him, he had to feel it on his own.

"Five changes in the path of 'yin' and yang......" Ye Feng's eyes flashed, and he faintly had a realization.

"The reason why soil can carry all things is because of its stability, its heaviness, and its broad ......," Ye Feng said to himself: "Isn't the balance of 'yin......' and yang stable?" A trace of earth vitality will be derived from the Heaven and Earth Vitality!"

While muttering to himself, he raised his hand, and the vitality of heaven and earth swept from all directions, turning into two kinds of vitality, 'yin' and yang. He began to try to balance the 'yin' and yang qi, since he had already done this once before when he comprehended the Soul Devouring Sword, so this time he quickly made the 'yin' and yang qi reach a balance, and a trace of earthy yellow 'color' vitality actually appeared!

"'Yin' and Yang are balanced...... It is the first change of the way of 'yin' and yang!"

Ye Feng's eyes flashed with 'essence', and he finally had a realization.

"Boom!"

Ye Feng Dantian's sea of 'yin' and yang qi suddenly turned, and the 'yin' and yang qi reached a balance, and the surface of his body suddenly froze, and the whole person instantly turned into an iceman.

Once you comprehend one of the changes in the path of 'yin' and yang, the body will have the phenomenon of alternating between hot and cold, and if you can't 'survive' it, you will die. If you can 'survive' the past, you can firmly grasp the changes in the way of 'yin' and yang.

Martial artists practice against the sky, and anyone who comes into contact with the "Tao" will be punished by the heavens!

At this moment, Ye Feng is receiving the "punishment" of the heavens, and if he wants to 'survive' the past, he must have extraordinary willpower!

The cold qi spread from his dantian to his whole body, and even to his soul! He had almost lost consciousness, the more powerful the talent, the more terrifying the cold qi became, and the longer he was tortured by the cold qi, the cold qi generated in Ye Feng's body was several times that of ordinary people!

......

Just when Ye Feng was suffering from the cold, in a certain room in Lang Huan Jingzhai, there was a circular light curtain in the void, and there was actually a person in the light curtain, it was Ye Feng!

"Master, I didn't expect him to comprehend the first change so quickly!"

The people around Huang Yuan are actually Traceless Sons!

The Traceless Boy looked at Ye Feng in the light curtain, and said with a faint smile: "His comprehension 'sex' is excellent, and what is even more rare is that he knows that he will die for a lifetime, and he has to fight for a chance, and many martial artists are precisely because they lack this kind of adventurous 'spirit' spirit, so they can't become a real master!"

Huang Yuan smiled, Traceless Sons did often teach them to dare to take risks, a person who is timid in doing things will not be able to achieve great things at all.

"His 'yin' and yang five changes are terrifying, if he can 'survive' it, his strength will be much higher than the others......" Childe Without a Trace muttered to himself.

"When the senior brother comprehended the first change, he suffered from the cold for a day and a night, and suffered from the heat for a day and a night...... He possessed the Soul Dao Seed and Destruction Aura, and his talent was even stronger than that of Senior Brother, so the time he needed should also be longer!" Huang Yuan said.

"At least three days and three nights!" said Childe Without a Trace with great certainty, the three days and three nights he said were worth all the time combined.

"Three days and three nights!" Huang Yuan's face changed, the master seemed to have experienced three days and two nights back then, did the master think that Ye Feng's talent far surpassed his own?

"When the dual dao species and the dual aura comprehend the five changes of 'yin' and yang, the time to suffer from heat and cold is at least three days and three night......s," the traceless son said to himself.

"He is indeed enough to be comparable to someone with a dual Dao type and a dual aura!" Huang Yuan nodded.

......

Two days and two nights later, Ye Feng was still frozen by the ice, seeing this scene, the face of the Traceless Son remained unchanged, but Huang Yuan was already shocked.

The suffering of the cold alone is two days and two nights, and this kind of talent is really shocking. It was only at this time that Childe Without a Trace and Huang Yuan realized that they had completely underestimated Ye Feng.

After another day and night, the ice on Ye Feng's body finally slowly melted. Although the cold was terrifying, he finally persevered with his super willpower, but when all the ice cubes melted, another wave of heat was generated in his dantian, flowing all over his body!

In an instant, his skin turned fiery red, and he felt the heat in his body burst at any moment.

"Ah......h

Ye Feng couldn't help but look up to the sky and roared, exhaling monstrous hot air.

A day later, Ye Feng's body had become shriveled up, like a dried corpse.

Two days later, Ye Feng's body was only skinny and bone, and the 'essence' blood in his body had almost been burned out by the heat.

Three days later, Ye Feng's vitality was almost gone, like a dead corpse!

Even the Traceless Son thought that Ye Feng couldn't hold on anymore, but at this moment, the heat in Ye Feng's body suddenly slowly dissipated......

The pain of the heat burning, he finally 'survived'!

After experiencing the first change of 'yin' and yang, Ye Feng's 'essence' qi and spirit improved synchronously, and the heaven and earth vitality swept in from all directions and drilled into Ye Feng's body. It didn't take long for Ye Feng's originally shriveled 'flesh' body to slowly recover, and after a few hours, he had become radiant, as if he had been reborn.

"Six days and six nights!"

The face of the traceless boy changed, both shocked and suspicious.

"Six days and six nights! If I hadn't seen it with my own eyes, I would never have believed that there was such a person in the world!" Huang Yuan was shocked.

Just when Huang Yuan was shocked, Ye Feng had already gotten up and walked into the sweet spring of life, and he wanted to comprehend the second change of the 'yin' and yang paths!

The water is sometimes soft, sometimes rigid, soft and pervasive, and indestructible when it is rigid!

Why is there water in the world? Ye Feng asked himself, he felt that as long as he found the answer, he would be able to successfully comprehend the second change of the 'yin' and yang paths.

"The balance of 'yin' and yang is earth, so when the two qi of 'yin' and yang reach what state can it be water?" Ye Feng muttered to himself, opened his palm, touched and 'touched' the sweet spring of life, looking for the essence of the sweet spring of life!

He entered the primary state of meditation, and in this way he 'touched' the fountain of life and meditated quietly.

A day later, his eyes suddenly flashed with 'essence', "Yang Qi decreases, 'Yin' Qi increases, and when it reaches a certain state, it can produce Water Vitality!"

He began to experiment constantly, gradually introducing yang energy and increasing 'yin' energy at the same time.

After thousands of attempts in a row, he finally let the 'yin' and yang qi derive the 'sexual' vitality of the water genus!

"Boom!"

The Heaven and Earth Yuan Qi around Ye Feng reversed, and at the same time, a cold qi was born in his dantian again, and the cold qi entered his body, and he became an iceman again!

This time, he also experienced three days and three nights of cold air entering his body, and three days and three nights of hot air, and the second change of 'yin' and yang ended!

After experiencing the first and second changes of the 'Yin' Yang Realm in a row, he finally broke through to the middle stage of the 'Yin' Yang Realm, and his strength increased greatly!

"Master, I finally understand why you wrote the four words Nine Deaths and One Life, he did go through nine deaths and one life to get what he wanted!" Huang Yuan smiled.

Childe Traceless smiled but said nothing.

(I went to work yesterday, 8 o'clock in the morning, 6 o'clock in the evening, and it was 7 o'clock when I got home, and there were guests at home, and I was delayed for a lot of time, and I didn't write a chapter until 12 o'clock, so I could only change it.) ）

(Also, I wrote it last night and posted it this morning...... ）

(If I'm not mistaken, I've already made up three chapters, and now I owe another chapter, plus the three chapters I owe before, for a total of four chapters, and I'll 'take time' to make it up as soon as possible.) ）
