The moment the prohibition on the little black ball was lifted, a hazy halo rippled from above, and this power was very soft, directly acting on Yin Feng's state of mind.

In a trance, Yin Feng felt as if he was not sitting in the retreat room at this moment, but in a small dark room.

In a short time, this gentle force turned into an invisible energy sieve, constantly floating in his state of mind, filtering the impurities in his state of mind on its own.

During this period, Yin Feng's face distorted from time to time, revealing a look of pain, but fortunately, it was not the first time that he had used this power to temper his state of mind, so he had some experiences, even if it was extremely uncomfortable, like falling into a nightmare, it was not unbearable.

After a long time, Yin Feng opened his eyes and showed a look of joy, his state of mind was finally perfect again.

"Every time I polish my state of mind, it's so painful, I really don't know what kind of strength this state of mind will bring to me in the future?"

Yin Feng rubbed a handful of sweat from his face with his sleeve, and his complexion was a little sluggish at this time, because this power of heart refining was really too torturous.

If it weren't for the fact that the dry old man of Yamauchi Mountain had said that polishing his state of mind would give him unexpected strength, he really didn't want to suffer this sin.

To tell the truth, polishing the state of mind is simply more difficult than cultivating the spiritual spring, I don't know how many times, even the old man also said, even in his time, few people would bother to polish the state of mind.

It can be seen that even if you don't polish your state of mind, it will have no effect on your cultivation.

Yin Feng took out the soul-nourishing water, took a sip, and suddenly realized that it was raining in the sea, although the power on the little black stone was aimed at the state of mind, but those nightmare-like illusions were still a little damaging to the soul.

"The second time I drank soul nourishing water, it really didn't have any effect on the improvement of soul quality, but it was still good to repair the damage to the soul. ”

Yin Feng smiled, and after opening the prohibition on the little black ball, he put it in the storage bag again, and the burial elder taught him how to unlock the prohibition and naturally taught him how to restart the ban.

That mouthful of soul-nourishing water made Yin Feng's soul rejuvenate again, his soul light was blazing, and the tired look on his face disappeared.

Taking off his shirt, Yin Feng jumped into the pool configured in the retreat room and washed himself, after all, he was sweating a lot, wet, greasy, and uncomfortable.

As soon as he washed it smoothly, Yin Feng jumped out of the pool directly, the fire attribute true yuan flowed, and suddenly his whole body was steaming, blinking an eye, and he was extremely dry.

"Comfortable!"

Yin Feng was full of energy, and I have to say that the effect of the soul nourishing water was too good, making him full of energy.

Yin Feng sat cross-legged, and the smile on his face gradually faded.

After taking a deep breath, Yin Feng ran the trick, and suddenly all the acupuncture points around his body appeared.

He took out the sandalwood ring, and one elixir after another flew out, and then all entered Yin Feng's mouth.

These elixirs were all obtained by Yin Feng from the Ten Thousand Medicine Nest in the Abi Underground Palace, and as one elixir after another was swallowed by Yin Feng into his abdomen, those acupuncture points were also opened one by one, and the red light flickered, dazzling like a red glow.

It wasn't until Yin Feng swallowed more than fifty plants that all the acupuncture points in his body were opened, and this situation also made him a little speechless, you must know that the quality of these elixirs is no worse than those spirit peaches, and even much stronger.

A large amount of aura essence wandered among Yin Feng's limbs and hundreds of remains, and now he had no spiritual spring, so this majestic aura essence was all attached to his acupoints.

Yin Feng closed his eyes tightly, and continued to refine his body according to the cultivation mystery of the absurdity, turning the energy essence in his body to refine his body, and he could see that the energy in his whole body was like a tide, ebbing and flowing, and the wind was surging.

The aura in the entire retreat room was swirled by the surging energy band of his body, and finally a small aura tornado swirled around Yin Feng, and Yin Feng's body was located in the middle of the eye of the wind.

Although the aura in the retreat room cannot be compared to the treasure of heaven and earth, mosquito legs are also meat, and it is better to have them than nothing, and the amount of aura in this level of retreat is not just mosquito legs.

Of course, the main reason why Yin Feng chose to break through his cultivation in the first-level retreat room was because of the majestic power of heaven and earth here.

The power of heaven and earth in the aura tornado, all kinds of visions surged, one moment lightning and thunder, and the other moment the flames were raging.

Even the pool in the retreat room was affected, as if it had become a fountain, and the water exploded and steamed.

The majestic power of heaven and earth entered Yin Feng's dantian through the acupuncture hole, and finally all poured into the silver inner dan

As with the previous practice, the content of the absurd recipe is constantly innovating, the old characters disappear and new characters appear.

However, this time Yin Feng was a little moved, because the new characters that emerged were far more than before, which caused the cultivation on the absurd recipe to become longer and longer.

These newly appeared characters are filled with terrifying secret power, but fortunately, Yin Feng's soul power has grown amazingly now, and it is not what it used to be, otherwise something would definitely happen again.

"Huh?"

Suddenly, Yin Feng found that the silver inner pill in his dantian was actually slowly getting bigger, originally he thought that his inner pill would also be like those magic cultivators, the size would be fixed and unchanged, and only one would be condensed again.

Then this is not the case, and now that he has practiced to the end, the more he has different from Fa cultivation, but Yin Feng has long been surprised.

With the growth of Inner Dan, his true element amount is also growing wildly, if this explosive true element amount is measured by the realm of Fa cultivation, then Yin Feng's cultivation is changing from the Dan Dao Realm Triple to the Dan Dao Realm Quadruple, then the Dan Dao Realm is fivefold, and the Dan Dao Realm is sixfold......

With the growth of Yin Feng Neidan, this realm is still improving.

During this period, Yin Feng took out fifty elixirs from the sandalwood ring, his heart was dripping blood, and he was really distressed, although these elixirs were all obtained from the Ten Thousand Medicine Nest in the Ah Bi Underground Palace, but he couldn't withstand such a squander.

However, the distress is distressed, when it is really used, Yin Feng is not ambiguous at all, he also wants to see this breakthrough, what realm his inner pill can grow to, and how thick his true yuan can be.

Before coming to the Retreat Valley, he originally thought that as long as an inner pill was condensed in his body again, the breakthrough of cultivation would be considered over, and as for the true element, it was at most equivalent to the eightfold Dan Dao realm of Dharma cultivation.

It was also based on this consideration that when Hao Tianzhen said that Sha Tianyou's cultivation was the fifteenth level of the Dan Dao Realm, Yin Feng felt a little lost, because he couldn't cope with it in the short term, but now it doesn't seem to be like this.

Because at this moment, Yin Feng's true yuan amount had climbed to the tenth level of the Dan Dao realm, and this climbing process was still continuing.

Yin Feng was really a little excited, this breakthrough cultivation in the Heart Dao consumed so many heavenly and earthly treasures, and it was worth it.

But what made him even more excited was that his body was also slowly transforming, his skin was fluorescent, his heart was beating like a drum in the sky, and his blood was rushing like a river.

For physical cultivation, the body is the foundation, and it can be seen that those acupoint light spots outside Yin Feng's body are slowly changing from red to orange, which means that Yin Feng's body will soon enter the third turn of the desolate.

Previously, when Yin Feng broke through to the first transformation realm, the corresponding law cultivation realm was the fifth layer of the foundation building realm, and by the time he broke through to the second transformation realm, it was already equivalent to the third level of the Dan Dao realm.

Spanning from the fifth layer of the foundation building realm to the triple layer of the Dan Dao realm, the increase in strength in the middle was too huge.

It is conceivable that the ninth turn of the desolate, every time the body improves, Yin Feng's strength will increase wildly, and he even doubts that when he breaks through to the fourth turn of the desolate, he will directly jump out of the realm of the Dan Dao realm.

Although Yin Feng was not a law cultivator, he was naturally very curious about the realm behind the Dan Dao Realm.

For this reason, he had consulted many classics and asked Haotian Zhenren, but the result was that he didn't know what realm was above the Dan Dao Realm, which may sound ridiculous, but it was a fact.

Since Cang Jue established the Later Life Method, no one has broken through the Dan Dao realm, and it is said that Cang Jue himself has not broken through to that realm, leaving only the theory of cultivation.

In other words, the monks of the nine super sects are now stuck at about five hundred years old.

Five hundred years, this may be too long for mortals, but it is really a little short for monks.

Of course, there is no way to do this, this is the mutation of heaven and earth, the spiritual energy is exhausted, and the physical cultivation has been eliminated by heaven and earth, if it is not for the cantonment, these monks will not even be able to win five hundred longevity yuan.

However, Yin Feng understood that the abnormal changes in heaven and earth were not the natural evolution of heaven and earth itself, but man-made, and in the words of the old man, it was the winning side of the divine war.

As for the purpose of doing this, the burial elder refused to say much, but Yin Feng had an intuition that the mysterious forces behind the bark mask and the thousand-year-old city should all be related to the Divine War.

The fluorescence on Yin Feng's body surface became more and more intense, and you could see Yin Feng's chest muscles, abdominal muscles and other muscles constantly bulging, like a muscle giant, but after a pillar of incense, the muscles continued to contract, making his body appear in a well-proportioned and perfect state.

The aura tornado that surrounded Yin Feng was also getting stronger and stronger, the power of heaven and earth was surging, various visions were emerging one after another, and the entire retreat room was shaking slightly.

The retreat rooms are all closed to each other, and the isolation effect of the first-level retreat room is undoubtedly the best.

But even so, these retreat rooms were still affected, and the power of heaven and earth became much more disordered, restless, and most of those retreat disciples frowned, completely unaware of what was happening.

The elder who was guarding the retreat valley, his eyes that were originally closed suddenly opened at this moment, obviously sensing something, and after a long time, he said to himself in a daze: "With this son here, my Taiqing Red Sword Sect will return to the peak." ”

However, Yin Feng naturally didn't know these at this time, he sometimes wrapped his arms around, sometimes held the sky with his palms, and through changing postures, he guided the energy essence to swim all over his body and irrigate his flesh and blood.

Slowly, Yin Feng's body began to form a layer of withered skin, wrinkled, translucent, like a snake molting.

With the appearance of this layer of withered skin, Yin Feng's breakthrough state was finally coming to an end, and the growth rate of the silver inner pill in the dantian was also slowly slowing down, and finally it was completely frozen.

Yin Feng was a little dumbfounded, because his true yuan amount was equivalent to the fifteenth level of the Dan Dao realm.
