The sinuous and twisted iron chains spread inch by inch in the air, wrapped around Yu Sanjin's legs, and black flames jumped on them, between light and extinction, like the karmic fire of endless hell, full of mystical Dao Yun, revealing a palpitating atmosphere.

The black flame was very weird, wrapped around Yu Sanjin's legs, and it didn't burn his clothes, but followed his skin and drilled into his meridians, invading his body functions, and there were bursts of intense pain.

Lu Bin smiled at the corner of his mouth, and said gloomily: "Senior Brother Duan, how does my purgatory chain's magical power feel? To tell you the truth, these corpse fires were collected by me after all kinds of difficulties, specifically eroding the vitality of the human body!"

After the other party said it, Yu Sanjin really felt that the vitality of his body was slowly devoured under the scorching of the strange black fire, which was somewhat similar to the yin qi on the original evil king.

He wanted to break free from the chain of purgatory, but the more he struggled, the tighter he entangled, this magical power was the derivation of Lu Bin's powerful true qi, how could he break free?

Seeing that the vitality in his body continued to dissipate, Yu Sanjin was a little anxious, but he was at a loss.

At this time, after absorbing a large amount of true qi from the Tai Chi pattern of the dantian, he suddenly discovered the strange fire in the meridians of Yu Sanjin, and suddenly slammed it, and instantly bloomed with brilliant light.

As soon as the tentacle touched the strange fire, it began to tremble, as if it had encountered something extremely hobby, and with a bang, the strange fire was absorbed by the tentacles.

The chain of purgatory, as if it reflected that the foreign fire in Yu Sanjin's body was exhausted, twisted faster, and at the same time, those black flames that were extinguished poured into Yu Sanjin's body as if they didn't need money.

"Huh!" Lu Bin was a little surprised.

The chain of purgatory is very powerful, normally speaking, as long as a wisp of corpse fire, it is enough to exhaust the vitality of a monk like Yu Sanjin, but now, it suddenly poured into Yu Sanjin's body, which is really a bit weird.

The tentacles born from the Tai Chi pattern were like greedy mouths, frantically devouring the strange fire, and then transmitted back to the spirit pool.

The yin and yang fish became more condensed, and Yu Sanjin clearly felt that with the addition of black flames, the bottleneck of the three layers of his spirit pool was completely broken, and the edge of the three layers of the spirit pool also began to grow slowly.

Yu Sanjin suddenly thought of Lu Bin's words.

His own heavenly foundation is the Yin and Yang Dao Foundation, I don't know how much yin and evil qi he absorbed from the evil king, what corpse fire can compare to the yin and evil qi of an ancient corpse like the evil king?

This Lu Bin is using this Purgatory Chain to deal with himself, and to put it bluntly, he is to deliver food to the Yin Yang Dao Ji, no matter how much he comes, it is useless, and he is all devoured by the Yin Yang Dao Ji.

Soon, the flames of the Purgatory Chain became more and more dim, Lu Bin's face turned pale, the situation was obviously wrong, so many corpse fires poured into Yu Sanjin's body, but it was like a stone sinking into the sea.

Moreover, not only did the other party not have a trace of pain, but he was still humming comfortably.

It's no wonder that there are three catties left, because the bottleneck has been broken, the spirit pool of the dantian is already growing, especially the black flame added in and roared, which accelerated the growth of the spirit pool, and the circulation of true qi in the body became extremely comfortable, and he couldn't help but hum out.

Lu Bin didn't believe in evil anymore, he hurriedly increased the urging of his true qi, causing the black flames on the chain of purgatory to rise suddenly, no longer as bright and uncertain as before.

He believes that as long as he increases the erosion of the corpse fire, Yu Sanjin will definitely not be able to bear it, and he will eventually run out of vitality and be defeated.

Then, unintentionally, he made a big mistake.

Yu Sanjin broke through the third layer of the spirit pool, requiring a large amount of spiritual power, although the spiritual power of the three jars of monkey wine, although majestic, it was still not enough to maintain the growth of the four-layer spirit pool, if it were not for the black flame of the chain of purgatory, the spirit pool would probably have stopped growing.

Now, instead of stopping, Lu Bin has increased the urging of true qi, and if he provides a steady stream of true qi replenishment for Yu Sanjin's breakthrough cultivation, the effect is much faster than his cultivation with spirit beads.

The reason is actually very simple, in the final analysis, the chain of purgatory is just Lu Bin's magical power, the corpse fire is just the introduction, and the true qi is the source.

The more intense the black flame on the chain burned, it meant that the more True Qi Lu Bin instilled, and the more True Qi the tentacles of the Tai Chi pattern devoured.

Seeing how many black flames were born on the chain of purgatory, but how much were devoured, Lu Bin finally found that the situation was not good, and he hurriedly urged the supernatural power to try to recover the fire of purgatory.

Then, the Tai Chi pattern of Yu Sanjin Dantian was in a state of excitement at this time, and the tentacles slowly extended to the chain of purgatory, and the two were already connected.

Lu Bin wanted to withdraw his supernatural powers, but he was tightly grabbed by the tentacles, and he couldn't do anything.

He was shocked, and hurriedly stopped the output of true qi, trying to break free from the chain of purgatory, but unfortunately, it was too late, the tentacles of the Tai Chi pattern greedily devoured his true qi, even if he didn't urge, the true qi in his body was still like the quicksand of a funnel, and it was constantly grabbed by Yu Sanjin.

"You, you, what kind of evil method are you?" Seeing that one-third of the true qi in his body had been devoured, Lu Bin was shocked.

At this time, how could Yu Sanjin have the leisure to take care of him? The four-layer spiritual pool of the dantian had reached the most critical moment, and it was only a little longer to be able to complete the breakthrough.

It seems to be a trace, but in fact, it is the stage that consumes the most true qi, and the true qi that the tentacles grab from Lu Bin's body is also growing exponentially.

"Duan, Duan Yu, you are so ruthless, you are actually devouring my true qi!" Lu Bin couldn't control the leakage of his true qi and roared.

After only a breath of effort, less than half of the true qi in Lu Bin's body was left.

It's also terrible to think about, "Escape a True Technique" is a practice against the sky, after Yu Sanjin breaks through the Lingchi Realm, the medium-grade spirit beads used in cultivation are often tens of thousands, you can imagine how terrifying the consumption of this resource is.

Although Lu Bin was in the Fake Dan Realm, his true qi was extremely powerful, but the true qi required by the fourth layer of the remaining three catties of spirit pool was even worse than his fake pill, so he would swallow half of the true qi in his body in a short period of time.

If it weren't for the fact that there were three jars of monkey wine at the bottom before, I am afraid that the true qi in Lu Bin's body would have been devoured long ago.

"Let go of me, Duan Yu!" Lu Bin shouted in despair, his face pale.

It was really because the true qi was consumed too much, and since he was devoured by Yu Sanjin's true qi, he tried to urge other divine powers, but there was no reaction, as if he was locked up.

Just when less than one-third of the true qi in Lu Bin's body remained, the four-layer spirit pool in Yu Sanjin's body finally stopped growing. At the same time, the tentacles escaped from the chain of purgatory into the Tai Chi pattern.

Lu Bin felt that his whole body was loosened, and the chain of purgatory naturally dissipated, while he, staring at a pair of frightened eyes, looked at Yu Sanjin in horror, and hurriedly retreated a few feet away.

The feeling of being devoured by the true qi is too terrifying, with only three catties left and insisting on one more breath of effort, the true qi in his body will definitely be exhausted, and at that time, not only will his cultivation be lost, but he will also hurt the foundation, and he can only stop at the False Dan Realm in this life.

Yu Sanjin naturally didn't know what Lu Bin thought, his dantian slammed down, and the Tai Chi pattern bloomed with brilliant light again, spinning rapidly, and the entire spirit pool had already grown taller.

The fourth floor of the spirit pool is done!
