Hearing Bai Yueyin's words, Yi Yun was also a little surprised, he didn't expect Bai Yueyin to open his mouth and promise half a pool of divine milk chalcedony, which was a huge fortune.

Of course, everything has to be poisoned, otherwise, not to mention whether he can get this divine milk chalcedony pool, Bai Yueyin can't recover alone, and if the unknown existence kills him again, his life will not be guaranteed.

At this time, Yi Yun had completely dived into the Divine Pool, he urged the Aoki Divine Tree, and the rhizomes spread to the entire Divine Pond like an octopus, the Aoki Divine Tree contained majestic vitality, and what polluted the Divine Pond was the poison of the corrupt world, but the rotten qi of the great world, and the two were completely mutually restrictive.

Almost two hundred years have passed since Yi Yun got the Aoki Divine Tree, counting the time of Lethe River, when the Aoki Great World was ruined, the Aoki Divine Tree still had a strong vitality, and its huge root system still imprisoned the bronze giant.

Little by little, the Aoki Divine Tree absorbed the poison of the decay in the Divine Milk Chalcedony and purified them slowly, but the mysterious person who refined the poison of the decay was too powerful, and the process was not fast.

At this rate, it is difficult to purify it without seven or eight days, Bai Yueyin has obviously noticed this speed, if it takes so long, it will be too slow, she must heal as soon as possible.

Yi Yun was not in a hurry, his hand shook, and a wisp of black flame came out, it was the evil god fire.

In the "Medicine God Classics", there is a record of the poison of the rotten world, and naturally there are refining methods, and the evil god fire can burn everything, and just now Yi Yun entered the poison pool, he relied on the evil god fire to protect himself.

"Go!"

With a wave of Yi Yun's hand, the evil god fire spread, enveloping a ball of divine milk chalcedony and began to slowly refine.

With the sound of sneering, a large amount of the poison of the decaying world was burned into ashes by the evil god fire, but the divine milk chalcedony was not affected.

The "Classic Book of the God of Medicine" said that the divine milk chalcedony cannot be used to refine medicine, but can only be swallowed directly, or used to wash the body, the reason is that the fire will refine the medicinal properties of the divine milk chalcedony.

Bai Yueyin naturally knew this, originally saw Yi Yun using this method to refine poison, she also thought that Yi Yun would destroy a lot of divine milk chalcedony, but she didn't expect that Yi Yun's control of the evil god fire had reached the point where it was like a finger, the flame seemed to have life, and it was wrapped around the god milk chalcedony with great precision, and the toxic ingredients in it were completely burned, but it did not hurt the god milk chalcedony.

As time passed, the color of this mass of divine milk chalcedony wrapped in the evil god's flame became lighter and lighter, slowly turning into a pure milky white.

He's still an alchemist?

Bai Yueyin was slightly stunned, only an alchemist could do this, but he didn't expect Yi Yun to be young, and while he had a strength far beyond his age, he also knew the art of alchemy.

With the addition of the Evil God Fire, it is really much faster to go hand in hand with the Aoki Divine Tree, but even so, it will take four or five days to completely refine the divine milk chalcedony in this pool.

This time is still a little longer.

At this moment, a green crockpot flew out of Yi Yun's body, and as soon as this crockpot appeared, it exuded an evil aura.

This clay pot is the urn that Yi Yun got before, and what is placed in it is the ashes left by an ancient power.

After the urn appeared, it began to tremble violently, and Yi Yun could feel that the poison demon in the urn was extremely excited, and it couldn't wait to run out.

"Master, I can feel that these poisons are great supplements for me!" The poison demon was originally asleep, but after being summoned by Yi Yun, he felt the poison of the decaying world in this divine milk chalcedony pool, and he kept shouting in Yi Yun's sea of knowledge, and its eyes glowed green, just like a hungry ghost who had been hungry for many days, and suddenly saw a table full of Hans.

Yi Yun opened the urn, the poison monster screamed, his body turned into a green streamer, and he plunged into the pool of divine milk chalcedony!

This poisonous demon is originally poisoned, it is poison itself, it is not poisonous at all, it doesn't care about the poison of the world, it directly devours the divine milk chalcedony, and absorbs all the poisons in the god milk chalcedony.

A large amount of poison of the decaying world is precipitated in the body of the poisonous demon, but they do not harm the poisonous demon in the slightest, but nourish the poisonous demon, making the poisonous demon's power stronger and stronger.

And as the power of the poison demon increases, the speed at which it absorbs the poison of the decaying world is also getting faster and faster.

At this rate, the Evil God Fire, the Aoki Divine Tree, and the Poison Demon will be attacked from three sides, and it will only take two days at most, and the divine milk chalcedony in this pool will be completely refined.

In fact, as long as the Divine Pond cleared out a part, Bai Yueyin could start cultivating, and it hardly delayed her much.

Seeing the poison pool being purified at a speed visible to the naked eye, Bai Yueyin was also surprised in his heart, this Yi Yun, there are too many means!

Ordinary Venerable, seeing the poison of the decaying world in this pool, he is afraid that he will not be able to avoid it, even those strong people who are proficient in pharmacology are afraid that they will be helpless, but Yi Yun used three methods to drive away the poison, and the most powerful thing is that he can also use three methods together, the Aoki Divine Tree and the Poison Demon are independent, and there is no need for Yi Yun to be distracted at all.

Bai Yueyin's gaze couldn't help but fall on Yi Yun's body, at this time, Yi Yun's whole body was shrouded in the green light of the Aoki Divine Tree, his black hair was flying, and there was a ball of divine milk chalcedony floating in front of him, which was burned by the fire of the evil god, while the green poisonous demon flew around, surrounding Yi Yun.

How did this young man grow up, Bai Yueyin has established the Kingdom of God for tens of millions of years, but no matter how vast and infinite the Seven Desolations Continent is, such a freak has never been born.

Slowly, the speed of the poison demon's expulsion has surpassed the speed of Yi Yun's refining and detoxification with the fire of the evil god, and it is still growing.

Not to mention Bai Yueyin, even Yi Yun, who was the master of the poison demon, was surprised, he found that the poison of the rotten world seemed to have the same origin as the poison demon, and it was precisely because of this that the poison demon devoured the poison of the rotten world so easily, and the strength grew so fast.

"Do you mean ......?"

A flash of inspiration suddenly flashed in Yi Yun's mind, the poison demon was born in the green urn, the ancient power in the urn was poisoned and died, after his death, his body was refined and burned, but the poison did not die, but remained in the ashes.

And the poison demon that was subdued by Yi Yun was born from the toxin of the ashes.

This made Yi Yun inevitably think, maybe hundreds of millions of years ago, the dead power in the urn was also killed by that mysterious person, and it was also because of this that the poison demon would come from the same origin as the poison of the decaying world in the god milk chalcedony pool!

This association made Yi Yun's expression solemn.
