Just when Luan Yu stretched out a hand and pressed it into the void in front of him, the entire hall unexpectedly emitted a buzzing sound.

Immediately afterwards, the space in front of Xiao Yu was like a broken glass curtain wall, shattering into countless cracks, and after a while, pieces of space fragments collapsed, revealing the world opposite the "glass curtain wall".

I saw that there was a quiet and peaceful courtyard, and facing Xiao Yu were two unpretentious tile houses, in which two willow trees with lush branches were planted on the left and right, and the branches were also swaying slightly with the breeze.

"Come with me. Luan Yu turned his head to say hello, and then he stepped straight into the shattered space and stepped on the soft grass in the small courtyard.

Although Xiao Yu was curious about this scene, because he had a more advanced Huaxia realm, this small courtyard hidden in the gap between the spaces would not surprise him at all.

Xiao Yu followed closely behind and followed Luan Yu's footsteps into the courtyard.

"Don't be surprised, don't make any noise, Uncle Zhang needs to take care of himself. Luan Yu looked at Xiao Yu's eyes and said, after all, he expected that Xiao Yu would be shocked by this space opened up alone, but he only saw the calm of the ancient well from Xiao Yu's eyes.

"Good boy, no wonder Uncle Zhang will have a friendship with you, this concentration is really not comparable to ordinary people. Luan Yu praised in his heart.

"Good. When Xiao Yu heard Luan Yu's words, he just nodded and gently spit out a good word.

"Cut, what have you seen! This courtyard is placed in the Huaxia realm, and it can't even be counted as a hair, but there are mountains, rivers and rivers there in the master's place. Xiao Yu thought with disdain in his heart.

"Come with me. With that, Luan Yu walked towards the tile house on the left.

"Squeak... ”

After a few moments, Luan Yu gently pushed open the door, and then the two of them rushed in, entering the washer where Youlian Sanren was recuperating.

"It smells so strong... ”

As soon as Xiao Yu stepped into the house, the strong smell of herbs hit his face, almost choking him. And when his gaze swept the room, he also found the reason.

It turned out that next to the big bed where Youlian Sanren was recuperating, there was actually a hollow wooden collapse, and under the wooden collapse was a tile fence used to bake medicinal powder, and now there were several precious herbs being roasted on it.

"It's a very good medicinal herb, but it's been wasted like this... It's a real tyrannical thing. Seeing this scene, Xiao Yu couldn't help frowning, and he also had a lot of doubts about the Qinglian Sect's alchemy technique in his heart.

"It seems that Yan Nangui has just been here... Luan Yu said softly. "Little friend, if you have any discomfort with the smell of medicine, you can go to the courtyard and wait first, these herbs will be roasted dry in about half an hour. ”

"That... Then I'd better go out and wait first. To be honest, Xiao Yu really couldn't accept such a strong and choking taste, so he asked Luan Yu to wait in the courtyard.

After a few moments, the two returned to the courtyard and closed the open door tightly.

"Sect Master, can you tell me who came up with this method? I'm really curious. Xiao Yu asked.

"Oh, hehe, this is exactly the method that Yan Nangui, the master of my sect's Danbi Hall, came up with, saying that this will help Uncle Zhang absorb the medicinal power even more. Luan Yu smiled and said.

"Danbitang Yan Nangui? hum... Hearing Luan Yu mention this name, Xiao Yu had a bad premonition in his heart, I'm afraid this weird method is not to save people.

"What's the matter, have you heard of Hall Master Yan?" Seeing Xiao Yu's expression, Luan Yu asked curiously.

"Oh, I haven't heard of it yet, but I am very curious about the method he came up with, and I wonder if the sect master can explain it to me. ”

"Hehe, you don't have to be polite, anyway, it's still early, so I might as well tell you about the physical therapy method created by the master of Yantang. ”

After Luan Yu's unsparing explanation, Xiao Yu also understood the pros and cons of this method, in Luan Yu's opinion, for unconscious people like Youlian Sanren, the method of physical therapy is beneficial and harmless, but in Xiao Yu's view, this method will hurt the patient's roots, and there will be no harm but no benefit.

The reason why the body therapy method needs to roast the medicine is to bake out the essence of the herbs, so that the patient can draw the essence of the medicine from the pores of the skin and breath, and give full play to the effect of the herbs to the greatest extent.

In Xiao Yu's cognition, this seemingly perfect solution has a fatal flaw, that is, it cannot eliminate the poisonous part of the dross of the herbs through the burning of the flame, and under the simultaneous roasting of different kinds of herbs, this hidden toxicity will merge with each other, thus evolving into an invisible poison that kills people.

Moreover, the reason why the ancestors of the past dynasties refined the herbs into the Dan through the Dan furnace is to remove the impurities, so that it is convenient for people to use them orally, and this way can completely discharge the impurities that remain in the Dan medicine through various organs of the person, so as to only absorb the medicinal properties and filter out the toxic part.

But this method of physical therapy is completely contrary, neither does it remove the toxicity, nor can it be filtered by the organs, and perfectly condenses the poison in the body, so that people are unknowingly infected with poison, and after the toxicity accumulates to a certain extent, I am afraid that even Da Luo Jinxian has no way to return to the sky.

"Hmph, Danbitang... Originally, you didn't mess with the master.,I'm too lazy to bother with your business.,But now... Since you're planning to murder the Youlian Sanren, then wait for me. Xiao Yu was ruthless in his heart, and the expression on his face also showed a trace of unnaturalness.

"Hehe, it seems that this is a bit esoteric for you, but it doesn't matter, the way of refining medicine is originally a talent, like this sect, although he is the master of a sect, he almost doesn't know anything about alchemy medicine. Luan Yu saw the strange expression on Xiao Yu's face, and thought that he couldn't understand the knowledge of pharmacology at all, so he said comfortingly and gently.

"Hmm... Sect Master, I still have some knowledge of medicine, but I really think there is something wrong with the physical therapy method you mentioned... Xiao Yu was stunned for a moment, and then explained to Luan Yu.

"Oh, Xiaoyou can also refine medicine?"

"I know a little bit about it, but I also thought about it by myself when I was at home in the past, and I couldn't get into the hall of elegance. The reason why Xiao Yu said this was not because he was modest, but because it was impossible for him to tell the whole story of how he got involved in alchemy, after all, it involved the biggest secret in his heart.

"Hehe, it seems that Xiaoyou still needs to study a lot, refining medicine seems easy, but it is intertwined, and it is not good at all without a little talent. ”

"Yes, the boy was taught. Xiao Yu bowed down and expressed his gratitude, but this idea was not at all in his heart.

"Sect Master, I see that the time is almost up, why don't we go in and have a look?" Xiao Yu roughly estimated the time, and then planned to enter the Washe again to see the state of Youlian Sanren at the moment, and the more important reason was that he wanted to see what those few herbs that had been roasted and dried were all about.

"Okay, it's been almost half an hour, let's go. After saying that, Luan Yu and the others pushed open the door of the Washe House again and walked in lightly.

At this moment, a large part of the medicinal smell in the house has dissipated, and Xiao Yu, who came in again, did not feel choked.

"Xiaoyou, Uncle Zhang's current state is still unstable, so don't disturb him, if something goes wrong, you and I can't bear this sin. Luan Yu warned softly.

However, Xiao Yu didn't speak, but nodded mechanically, because his gaze had completely fallen on the few dried herbs.

"Soul Grass... Manyoulin flower... This spirit grass... And also... What is this?" Xiao Yu's spirit was completely focused on the herbs, and he didn't pay any attention to Luan Yu beside him at all, and walked directly to the tile fence where the herbs were roasted and squatted down.

Then, Xiao Yu pushed aside the few herbs he had identified, stretched out two fingers and picked up the only remaining branch-like thing.

"Click... ”

There was a soft sound, and the branches that had completely lost their moisture broke between Xiao Yu's two fingers, and this sudden scene also caught him by surprise, and he almost knocked the thin tile fence to the ground.

Seeing this, Luan Yu hurriedly stepped forward, pulled up Xiao Yu, who was squatting on the ground, and asked in displeasure, "What do you see these herbs doing?"

"This... Being asked by Luan Yu like this, Xiao Yu suddenly realized that his behavior was a little rude, but now that he was focused on the branch, he directly ignored Luan Yu's questioning and said.

"Sect Master, do you know... What is this?" As he spoke, Xiao Yu leaned down slightly again and carefully picked up the broken branch.

"Didn't you come to see Uncle Zhang, why are you so interested in this thing now?"

"This... I have a hunch that this thing is anything but ordinary, and I hope that the sect master will give me advice. Xiao Yu said softly, and then gave another salute.

"I don't know what you're going to do... Luan Yu said puzzled. "This thing is also known from the mouth of the master of the Yan Hall, the name of this thing is called the Awakening Divine Branch, and its medicinal properties can protect the injured person's mind and make it unconscious. ”

"Awakening Branch... Xiao Yu closed his eyes and thought about it after hearing this, because of Ye Lao's directing and Mo Tianming's family biography of the "Dan Sutra", his understanding of herbal medicine is still quite sufficient.

When Luan Yu mentioned the medicinal effect of the Awakening Branch, Xiao Yu turned out a medicinal herb with the same appearance and effect in his memory.

"Lianhua Branch... It seems that the only thing that can maximize the toxicity of the drug is it. ”
