Zirong and the others saw the anxious appearance of several old men, but they didn't know why, and they all looked at Mu Hanyan suspiciously.

Mu Hanyan didn't hide it, and briefly talked about the dangers of refining the Soul Breaking Pill.

After listening to Mu Hanyan's words, everyone looked at Yan Zishu again, and their eyes changed slightly.

"Don't say it, the so-called healer, it is my duty to help the world and save people, legend has it that in the past, my ancestor of the medical Tao tasted all kinds of herbs to save the people, and finally died under the poisonous weeds, if I can't even do this thing, what qualifications can I call myself a doctor, and what face will I see when I die in the future.

What's more, entrusted by others to be loyal, Miss Mu did three things for me, and I should treat her friend at any cost, which is also the rule of my Yan family. The old men were still trying to persuade each other, but Yan Zishu interrupted them and said categorically.

Seeing his righteous words, Mu Hanyan had a little admiration in his heart, although this old man was a little small-bellied, but he would practice what he said, but he was not unfair.

"Senior Yan, I blamed you for being wrong, and I apologize to you. Ling Baobao stepped forward and said.

"That's it, if you want to say it, I should apologize to you, I was only thinking about how to make things difficult for you before, and I didn't even check the poisonous hair in Zirong's body and opened my mouth rashly, which is really a loss of medical duty. Yan Zishu waved his hand and said ashamedly.

Afterwards, Yan Zishu took out the eight purple cloud furnaces that had been repaired by Mu Hanyan before, and asked everyone to leave the Danling Hall and wait outside the door. It seems that he is not completely sure of refining the Soul Breaking Pill, for fear that failure will affect others.

The flames in the Dan furnace were swaying, and hundreds of medicinal materials were neatly placed next to them, exuding a refreshing fragrance.

Speaking of which, these hundred kinds of medicinal materials are all rare medicinal materials worth thousands of gold, and a few of them are even Mu Hanyan for the first time, and they have only seen pictures in medical books and ancient books before. These medicinal materials, even if they are taken alone, can be very beneficial to cultivation, if they are refined into pills with different pills, they can be refined into a good elixir that replenishes qi and benefits the yuan to improve cultivation, but who would have thought that according to another pill recipe, fused together, it can refine a highly poisonous pill that makes people smell and change color.

Yan Zishu's eyes were slightly condensed, and he felt it carefully with his thoughts, and suddenly, a series of hand-to-hand duels were played in his hands, and the fire of the furnace was also strong and weak and high and low with the Dan furnace.

A purple light flashed from the Dan furnace, and almost at the same time, Yan Zishu turned on the furnace fire, threw a few medicinal herbs into the Dan furnace, and then covered the Dan furnace, the speed was so fast that it was difficult to argue with the naked eye.

Then, he continued to fight the duel, and when the Dan furnace flashed purple again, he threw a few other medicinal herbs with lightning speed.

This was repeated for several rounds, until he threw all the hundreds of medicinal materials into the Dan furnace, and almost no one could see his movements clearly.

Mu Hanyan secretly admired it, her alchemy technique mainly relied on the perception of the Starfall Eight Desolation Sword, and there was also the assistance of Chaos Heavenly Fire before, aside from these two, just talking about the grasp of the fire, she was actually far inferior to Yan Zishu. Of course, this is also normal, others have practiced alchemy all their lives, and she has only studied it for a few days?

Immediately afterwards, Yan Zishu began to fight a duel, only to see a phantom light floating, as if the clouds were floating, and the essence of the duel was even more eye-opening for Mu Hanyan.

Mu Hanyan was not an arrogant person, it was rare to see such a strange alchemy technique, so he naturally would not miss it, and immediately focused on keeping it in mind and secretly practicing it in his heart.

A thick medicinal fragrance floated out of the doorway, and the smell made people feel like a fairy, but later, the medicinal fragrance became lighter and weaker, so faint that it was almost imperceptible.

The expressions of several old men who were worried before all relaxed, Mu Hanyan also relaxed, and Yan Zishu himself also showed a faint smile on his face.

Different from the general qi replenishing and benefiting yuan to improve cultivation, the higher the grade of the poison pill, the more colorless and tasteless it is, otherwise how can it poison others.

The fragrance of this medicine is getting lighter and lighter, which means that the medicinal power of the hundred medicinal materials is merging with each other, highly condensing, and it is not far from Cheng Dan.

The old men all stretched their necks to look indoors, and the few people in Huayue were also curious, how to say that it was also a legendary-level pill, even if it was a poison pill, the moment they could see the pill come out with their own eyes was also a kind of chance.

I don't know when, on the eight purple cloud furnaces, eight purple light patterns floated out, like colorful clouds floating.

"Eight doors rise from the clouds, the purple heart is one, and the Dan ......" Yan Zishu recited the Dan Jue, played the last hand, and was about to say the word "Dancheng", but his face suddenly changed.

The delicate Dan furnace suddenly trembled violently, and an aura full of violence and coldness was suddenly released.

Everyone outside the door had their faces changed.

Alchemy fails, sometimes it is just a waste pill, and sometimes it will blow up the furnace, for alchemists, it has long been commonplace, but this time the situation is different, Yan Zishu is refining the Soul Breaking Pill of the Afterlife, once the furnace is fried, he will definitely die.

"Let's go, you guys go quickly!" Yan Zishu shouted at the crowd outside the door while desperately fighting a duel.

Mu Hanyan could see that Yan Zishu was playing a sealing hand at this time, obviously wanting to seal the Dan furnace so as not to leak the poison and hurt the innocent. It's a pity that even under his seal, the Dan furnace is still trembling constantly, and the blue and purple smoke clouds are constantly seeping out from the gap between the furnace lid and the furnace body, and the violent and cold air in it is several times stronger than just now, which is the poison of the Soul Breaking Pill of the Past Life.

Under the erosion of that poisonous power, Yan Zishu's face also had a layer of green energy. Fortunately, this was just a little poisonous gas oozing from the cracks in the Dan furnace, otherwise even he wouldn't be able to resist it.

Mu Hanyan's face also changed, you must know that Yan Zishu is a master of the Sword Saint Realm, even if it is an ordinary seal, it will be multiplied in his hands, but at this time, he tried his best to fight the hand duel, but he couldn't seal the Dan furnace, which shows how fierce the poison is.

"Let's go, let's go!" Seeing that he couldn't seal the Dan furnace, and there was a sign of poisoning, Yan Zishu was even more anxious, and said to everyone outside the door.

The old men were shocked, but they didn't leave, they glanced at each other, gritted their teeth and rushed in, fighting at the same time in their hands, using the sealing technique, obviously wanting to help Yan Zishu.

Seeing their actions, Mu Hanyan's impression of them also changed greatly.

But unfortunately, their strength is still inferior, even if the three of them join forces, they can't seal the Nadan furnace.
