After Yin Feng left the valley where Duan Qiuling and the three were imprisoned, he flew towards the huge suspended palace in the sky again.

At this moment, he didn't have to worry about the safety of the three of Yuanluo, and after they 'swallowed' the Blood Evil Pill, they would no longer pose a threat to the Abi Underground Palace, and soon there would be their own elders to take them back.

Looking up at the air, Yin Feng felt that it should be this suspended huge palace, so that this Demon Dao Sect was called the Abi Underground Palace, because the name of this suspended huge palace was called the Abi Underground Palace.

This suspended Abi Underground Palace has a total of thirty-three floors, which is nearly twice as high as the Taiqing Palace of the Taiqing Red Sword Sect, and from the idle chatter of some disciples, Yin Feng learned that each layer corresponds to a stage of Dan Dao Realm cultivators.

For example, the first layer of the Abi Underground Palace corresponds to the first layer of the Dan Dao Realm, and the thirty-third layer of the Abi Underground Palace corresponds to the thirty-third layer of the Dan Dao Realm.

This also illustrates a problem from the side, that is, the cultivation of the strongest of the nine major sects in the Barbarian Land Region is probably the thirty-third level of the Dan Dao Realm.

Among them, the strongest elite-level powerhouses should all be about eighteen in the Dan Dao Realm, such as Tianyi, Mo Han and Ye Wanqing and others.

A powerhouse at the core elder level should be a powerhouse close to the thirtieth level of the Dan Dao Realm, such as the palm peak of the five sword peaks of Taiqing and the deputy palace master of the Abi Underground Palace.

As for the powerhouse of the sect master level, it should be a powerhouse who is infinitely close to the thirty-third level of the Dan Dao realm, or has reached the thirty-third level of the Dan Dao realm.

And Yin Feng felt that his current cultivation position should be regarded as an ordinary elite level, and there was still a constant distance from the strongest elite level.

Approaching the suspended Abi Underground Palace again, Yin Feng found that this suspended huge palace was distributed in the shape of a tower, with the largest area on the first floor and the smallest area on the thirty-third floor, like the spire of a pyramid.

"Isn't that huge statue a hastiness!"

After coming to the first floor of the Nose Underground Palace, what catches your eye is a huge figure sculpture, holding a huge scroll, with a compassionate expression, and the huge statue on the wooden sword peak, which is similar in shape, this statue is the cangjie saint who created the acquired cultivation method.

"It seems that both the Demon Dao and the Righteous Dao have a lot of respect for this Cangjue. ”

Staring at the statue of Cang Jue, Yin Feng's eyes also showed respect, but when he completely walked into the first floor of this Ah Bi Underground Palace, the respect in his eyes was completely replaced by surprise, this first layer was too big, there was a sense of emptiness on land.

There was a huge ring in the middle, and the ring was surrounded by a faint energy shield, and the surface of the ring was dark red.

Yin Feng found that that kind of red was not an ordinary red, but a kind of red soaked in blood.

It can be seen that there are countless people who have died in this ring, and the jade stones that make up the ring have been soaked into human blood stones by blood donation, which is strange and terrifying.

Yin Feng frowned deeply, feeling that the killing aura of the Ah Bi Underground Palace was too heavy, he was now a little glad that the trajectory of his fate had been changed by Xingchenzi, and when he thought of the situation where he was slashing people everywhere with a machete every day, he couldn't help but be afraid for a while.

He guessed that perhaps it was precisely because Xingchenzi changed the trajectory of his fate that Guigong couldn't calculate his fate, and felt that his fate was nothing.

"Huh, why is it so bloody?"

Yin Feng frowned, and he flew towards the direction where the smell of blood was the strongest.

"Huh, that's?"

Coming to the source of the bloody qi, Yin Feng was shocked, it was a huge jade jar, which was filled with blood-red liquid, and the thick bloody qi was constantly floating out of that jade jar.

Yin Feng saw a young man sitting in the bathtub at the moment, closing his eyes and cultivating, and he saw that there were wisps of black-red gas constantly overflowing from the bright red liquid.

As if pulled by some mysterious force, those black-red mist began to wrap around the disciple's body, and then slowly seeped into his flesh and blood.

"What kind of secret method is this?"

Yin Feng was puzzled, he felt that the reason why the body of the disciple of the Ah Nose Underground Palace was so strong was probably not only because of the cultivation of demonic qi, but also because of the secret method in front of him.

He could clearly sense that as those black and red gases continued to melt into that disciple's body, the aura exuded from the other party's body was slowly becoming stronger.

However, Yin Feng could see that this kind of path to make the body stronger was not a path of physical cultivation, it was just a simple way to make the body stronger, and there was no change in cultivation.

Yin Feng is different, while his body is getting stronger, his cultivation is also improving, and there are more hidden treasures in his body.

"Could it be that this kind of cultivation secret method is related to the immortal blood code of the Abi Underground Palace?"

Yin Feng's eyes showed a look of thought, but soon this thought was replaced by weirdness, because Yin Feng found that some of the black-red mist in the bathtub had actually been absorbed by the desolate ding.

Inside the Wild Ding, Yin Feng looked at the black, red, and red mist that was constantly gathering above his head, and began to stroke his chin, this is interesting, this Wild Ding is clearly stealing the essence of that disciple's body training.

However, Yin Feng was not surprised by this phenomenon, because when he left the outer gate for the first time to practice, every time he killed a brute beast, there would be a ball of blood essence that was absorbed by Huang Ding, and when he killed Bu Tian, there was also blood essence that was absorbed by Huang Ding.

The black-red mist can be absorbed by the desolate ding, indicating that the bright red liquid should be blood, and the large vat full of blood does not know how many creatures have been harmed.

Yin Feng stretched out his hand and detained the black-red mist that was condensing on the top of his head into his hand, and after a careful look, Yin Feng found that this black-red mist contained both the blood essence of human monks and the essence of the blood of fierce beasts.

Among them, the blood essence of fierce beasts accounts for 80 percent, and the blood essence of humans accounts for only 20 percent.

With a flick of his fingers, Yin Feng sent the black-red essence mist back above his head, allowing it to condense with the other mist.

Now, he hadn't seen the immortal blood code of the Nose Underground Palace, so that black-red mist was of little use to him.

If you use it to cultivate the absurd trick and improve your cultivation, it will be even more nonsense, after all, this is not the method of physical cultivation at all.

Although the monk's blood does have a strong blood essence qi, if he absorbs these blood essence qi and fuses it with his own flesh and blood, he can indeed achieve the purpose of becoming stronger in the flesh, but the effect is far less than that of heaven and earth.

Yin Feng was a little puzzled, if the immortal blood code of this Ah Nose Underground Palace was just a secret book that made the body grow stronger, it was really difficult to compare with the supreme sword code of the Taiqing Red Sword Sect.

Moreover, this kind of body enhancement does not help the improvement of cultivation at all.

But that day, when Mu Kun introduced the Supreme Sword Codex, he did list the immortal blood code of this Abi Underground Palace separately, stating that it could be juxtaposed with the Supreme Sword Codex, the Tao Sutra, etc.

"It's not just about strengthening the body. In the Wild Ding, Yin Feng said in a firm tone, Mu Kun's words, he did not question it at all, the only possibility was that he had not yet discovered the mystery of the Immortal Blood Codex.

Leaving this room, Yin Feng went to the next disciple's residence.

Similarly, the disciple was also sitting in a jade jar filled with red blood, wisps of black-red blood mist constantly melting into his body.

"The state of cultivation is so deep, I'm embarrassed to disturb, but I can't help it, I don't have much true yuan, so I can only borrow some true yuan from you. ”

Yin Feng's face was strange, and then he directly let the desolate ding reveal from the void, and with a flash of red light, Yin Feng's figure appeared directly behind the disciple.

Anyway, the first layer of the Ah Bi Underground Palace was all a disciple of the Dan Dao Realm, and there was no threat to Yin Feng at all.

The disciple was still immersed in his cultivation, completely unaware of anyone behind him, but when he found that someone had invaded his room, it was also when he fainted from the pain.

Yin Feng clapped his hands, this was also a helpless move, controlling the Wild Ding to walk through the void, it was too consuming the true yuan.

If he didn't rely on himself to slowly replenish the consumed true yuan without the help of heavenly and earthly treasures, it would undoubtedly be too long, after all, even if the first layer of demonic qi in this Ah Bi Underground Palace was much stronger than the one below, he could still only open four acupuncture points, and the speed of recovering the true yuan was too slow.

To be honest, Yin Feng is now glad that he healed Li Wan, because it was in the process of healing that he discovered the characteristics of his Silver True Yuan, which can convert the True Yuan of any attribute into a Silver True Yuan for his own use, and quickly replenish and consume.

Yin Feng once again firmly believed in the old saying, if God closes a door for you, then it will definitely open a window for you, but it depends on whether you can find this window.

Yin Feng wrapped his strong soul power around the soul of the disciple who was knocked out by him, which was considered to be a disguised seal of all the other party's senses.

Because the secret of the silver true yuan can't be known, after all, Yin Feng now feels that he doesn't have enough strength to protect himself, and being cautious is Yin Feng's code of conduct.

But fortunately, since the black spot in Yin Feng's mind moved to the center of the soul villain's eyebrows, it began to be controlled by Yin Feng's divine thoughts, otherwise he would have devoured the soul origin of this fainting disciple in a daze.

Indiscriminate killing of innocents is definitely not Yin Feng's style, and the disciples of the Demon Dao are not necessarily extremely vicious, insidious and cunning.

Yin Feng slowly sent a wisp of silver true yuan into that disciple's body, and he was also invisible to the other party's dantian and inner dan, but he could feel the other party's true yuan fluctuations.

Following the flow of the other party's true element, and touching the melon along the vine, you can naturally touch the position of the other party's inner dan, this disciple's true yuan is a fire attribute, but it is much darker than the true yuan of the fire attribute of the righteous path disciple.

Generally speaking, the five elements of the inner dan of the monk who practice the pure yang qi are the yang five elements, while the five elements of the inner dan of the monk who practice the turbid yin qi are the five elements of yin.

Yin Feng's wisp of silver true yuan flowed along the disciple's true yuan, and soon touched the other party's inner dan, because the inner dan was invisible, so what Yin Feng saw was a sea of fire, not a round red inner dan.

However, Yin Feng knew that that roaring sea of fire was the other party's Neidan, and after that silver wisp of true yuan mixed into that sea of fire, it instantly enveloped a wisp of flame.

The Silver True Yuan squirmed, and immediately expanded in a circle, then wrapped, and finally expanded again, and after a quarter of an hour of repeated cycles, the volume of the Silver True Yuan expanded by more than a hundred times.
