Calm was restored in the void, and the four Great Emperors, including the True Dragon and the Heavenly Demon, submitted to Du Feiyun.

The four emperors, including Yuxu and Kunlun, were still hiding in the corner, watching coldly, not daring to interject and speak, Du Feiyun's strength was so strong that they were extremely afraid of it.

The trouble in front of him has been solved, but there is still bigger trouble waiting for Du Feiyun.

Emperor Taishi and his relatives and friends, as well as the White Emperor Zhong Xiaobai, were all hit by the source of ten thousand poisons, and only their heads were left that had already been corrupted, and their lives were short.

In particular, the Taishi Emperor's injuries were the most serious, he was not only hit by the source of ten thousand poisons, but also was injured by the Miaoyin Emperor with a move, and only half of his head was left, and the poison had already invaded the sea of knowledge and the soul.

"You are all my dearest, and I will not allow you to die!"

Looking at the tragic situation of his relatives and friends, Du Feiyun was furious in his heart, and he couldn't wait to kill Miaoyin and the Thunder Punishment Emperor immediately. But he knew that saving people first was the most important thing.

With almost no time to breathe, Du Feiyun immediately exerted his divine power to check the injuries of the Emperor Taishi. Emperor Taishi was the most seriously injured, and he had to be saved.

The majestic and gentle divine power poured into the head of the Emperor Taishi from Du Feiyun's palm, and his injuries were quickly ascertained.

Emperor Taishi is already at the end of his powerful crossbow, dying, the defense of the sea has collapsed, the poison has invaded, and even the divine soul has been contaminated with poison. At this time, the Emperor Taishi was already delirious.

Du Feiyun didn't think much about it, and immediately used his majestic divine power to expel those poisons that were causing chaos in the Taishi Emperor's sea of knowledge.

However, what he didn't expect was that even if his divine power was majestic and vast, surpassing the limit of the Great Emperor, it was still difficult to expel the poison. The poison is extremely stubborn, although he expelled and refined most of it, but there are still some poisons that penetrate deep into the soul of the Emperor Taishi and are deeply rooted.

If Du Feiyun forcibly used supreme divine power to expel those poisons, he would inevitably hurt the Taishi Emperor. even directly shattered his soul, so that the Emperor Taishi would die immediately.

Du Feiyun checked the injuries of the others again, and the results were similar, the poison had almost corroded their heads, and only Zhihai and Shen Soul remained.

Moreover, although everyone has not been invaded by the poison for the time being, the sea of knowledge is full of holes and is on the verge of being broken, and the poison has corrupted the entire sea of knowledge.

"It is worthy of being the source of all poisons, it is so vicious and powerful!"

"No, I can't. I can't help them get rid of the poison, but with the help of an outside force, although I may be able to pull out the poison, they will also die. They must rely on their own strength to expel the poison from the inside out, but now that they are so weak that they are dying, how can they have the strength to expel the poison?"

"Yes, I still have the elixir. Try to see if the elixir can save their lives!"

Thinking of this, Du Feiyun did not hesitate to take out a few Taichu Pills from the Yan Emperor Ding, slapped the pill into the Taishi Emperor's skull with one palm, and wrapped it with divine power to dissolve the medicinal power. Slowly transported to the Emperor Taishi.

At the beginning, after everyone took the Taichu Pill, their strength increased greatly, and Du Feiyun knew that the medicinal power of this medicine was extremely powerful, and it would be of great use in the future. So I took the time to refine a lot, and now it comes in handy.

Unexpectedly, although the Taichu Dan surpassed the limit of the Divine Pill. It is one level stronger than the elixir refined by the Great Emperor, but it is still difficult to resist the source of ten thousand poisons.

The medicinal power of the Taichu Pill can only help the Emperor Taishi repair his physical injuries and help him recover his majestic immortal power, but it cannot completely remove the poison, which is equivalent to increasing his strength and living for a few more years.

"No, the Taichu Pill can't heal the injuries of the Source of Ten Thousand Poisons, I have to refine a better pill!"

Now, everyone has been injured by the source of ten thousand poisons, and it is not possible to rely on external forces, but only by taking pills. But the Taichu Pill couldn't solve it, so Du Feiyun could only find a way to refine a better pill.

Thinking of this, Du Feiyun waved his hand and put everyone's heads into the Yan Emperor Ding, and sealed them in the Aoki World Realm with a formation.

The Aoki World Realm is the most abundant and powerful world realm of the Eight Extremes of the Yan Emperor Ding, where everyone can absorb the aura and vitality and resist the erosion of the source of all poisons. Moreover, in order to help everyone absorb the aura and vitality, Du Feiyun laid a formation seal to help them gather the aura and vitality.

Moreover, these formations can also change everyone's time, so as not to make the time flow in the Yan Emperor Ding fast, and before Du Feiyun can refine the pill, a hundred years have passed, and everyone will already die.

After that, Du Feiyun gave everyone another Taichu Pill to prolong their lives, so that everyone could resist the poison for a few more years, so as to buy him time to refine a better elixir.

After doing all this, Du Feiyun returned to the alchemy space, and his divine sense swept through the entire treasure house of the Yan Emperor Ding, searching for the most precious and strange medicinal materials and preparing to refine the pill.

"What kind of elixir can we refine, how can we surpass the Taichu Pill and refine a better elixir?"

In front of him, there were thousands of the most precious medicinal materials in the world, like a hill, Du Feiyun began to meditate hard and fell into deep thought.

Although, before he refined the Taichu Pill, he was known by everyone as the number one alchemist in the world, which was enough to be named Medicine Venerable or Medicine Saint. In the whole world, the person who refines medicine is no more powerful than him.

But he himself knew very well, he clearly sensed that although he had reached the limit in the way of alchemy, he was proud of the world and was the first person in the world.

But he encountered a bottleneck, a bottleneck that was ultimately the most esoteric, an incomparably ethereal bottleneck.

can't break through this bottleneck, he is still the number one alchemist in the world, but he is no different from other alchemists, they are all ordinary alchemists, but their strength is stronger.

But if he crosses this bottleneck, he is still the number one alchemist in the world, but this meaning is different, he will be extraordinary, reaching another transcendent peerless realm, he and ordinary alchemists are already people from the two worlds.

Perhaps, this bottleneck is not the shackles of alchemy and strength, but the cultivation of perception, state of mind, or Taoism.

Thinking of this, Du Feiyun's mind was chaotic, and countless conjectures and speculations emerged. He frowned and fell into deep thought, like a monk who had retreated to the death, quitting the six senses and five senses, and was completely immersed in his own fantasies and calculations.

Time flies, time flies, and time flies in the Yandi Ding. Before he knew it, a hundred years had passed, and Du Feiyun, who was meditating hard, suddenly opened his eyes, and a trace of essence flashed in his eyes.

"I understand, for me, this bottleneck is the way to transcend ordinary alchemists, and if you want to break through the bottleneck, you can't stick to the category of ordinary alchemists, you have to integrate Dao comprehension. ”

"I have come to the end of the path of alchemy, but I have not yet comprehended the true meaning of the way of alchemy, only by comprehending the ultimate mystery, can I break through the bottleneck and go to the next level. ”

Thinking of this, Du Feiyun was relieved that he had found the direction.

The root of the problem is, what can expel or refine the source of all poisons?

The idea of an ordinary alchemist is that if you want to detoxify, you have to find the corresponding antidote herbs, and add other materials to refine the pills. But looking at the mountains of medicinal herbs and treasures in front of him, Du Feiyun couldn't think of anything that could resist the source of ten thousand poisons.

If you really want to talk about what can resist the source of all poisons, it is not some kind of medicinal treasure, but a kind of strength, the power of chaos, and the holy fire of chaos.

"The power of chaos is the power of the origin of heaven and earth, and the source of all poisons is also from its fireworks, so the power of chaos can expel poison. Before, I fused and refined the Chaos Holy Flame and mastered the power of Chaos, so I was able to help the Emperor Taishi expel some of the poison. ”

"However, the power of chaos is now my divine power, how can I turn my divine power into an elixir to give them a dose and help them heal their injuries and expel the poison?"

Admittedly, this is a difficult problem.

Ordinary alchemists have always used medicinal materials to refine pills, and clever alchemists can use everything in the world as medicinal materials to refine pills, but they have not heard of refining the divine power from cultivation into medicinal materials.

However, this problem did not confuse Du Feiyun for long, and was solved by him with his intelligence and boldness.

"The power of chaos is my strength, if you want to refine the pill, there is no other way than to use me as a medicinal material to refine the pill!"

"Ordinary alchemists have always used medicinal materials and genius earth treasures to refine pills, even if the medicinal materials are strange, they can't go beyond the realm of the world. Even if there is an alchemist from the evil demon outside the realm, who uses living people or monks as medicine to attract alchemy, it is still using other people's lives. ”

"And now, I am refining the pill as a medicinal material, this is simply an ancient anecdote, an unprecedented way of alchemy, this is beyond the limit of ordinary alchemists. ”

Many years ago, I realized the true meaning of alchemy, everything in the world can be used as medicinal materials, with all things as materials, and heaven and earth as medicine furnaces, which is the true meaning of alchemy. It seems that I was still shallow at that time. ”

"Now, I finally understand that the true meaning of the way of alchemy, the ultimate meaning is that everything in heaven and earth cannot be alchemized without anything. Whether it is a medicinal herb, a monk, or myself, it is a kind of strength. In the ultimate alchemy technique, what is refined is no longer materials and objects, but the amount of power!"

The self-talk in Du Feiyun's heart gradually confirmed, guiding him to deduce the true meaning of the Dan Dao. This feeling of breaking through the bottleneck and comprehending the truth of the ultimate avenue made him extremely excited in his heart, and finally couldn't help but laugh loudly.

Thinking of this, he immediately sat cross-legged in the alchemy space, and with a movement of his heart, the Yan Emperor Ding began to operate as a whole, and the alchemy space suddenly bloomed with hundreds of millions of flames and began to refine him.

Since ancient times, no alchemist has ever dared to refine his own pills, and Du Feiyun is definitely the first person in the world.

Of course, this process is extremely dangerous, and his life is also worried, and he may fail to refine at any time, and he will refine himself to death at that time.

But he is confident that now he has incomparably strong strength and lives with heaven and earth. Moreover, the Yan Emperor Ding is his natal magic weapon, and if there is a dangerous situation, he can also control it.

In any case, whether it is to save his relatives and friends, or to break through the shackles of the final bottleneck and become the first person in the Dan Dao and the peerless medicine ancestor......, he has to give it a try!
