With a "clang", the door suddenly closed behind him, and the room suddenly became dark. Dachun immediately blocked Li Hui, and Dazhuang stood behind Li Hui, and the two of them immediately remained alert.

Li Hui squinted her eyes and adapted to the light in the room.

"Come with me, three." A hoarse voice came from beside me.

The three of them turned around and saw the old Taoist terrible face beside them. Li Hui was so scared that his scalp was a little numb. At this moment, two rays of light were shining on the roof, and they were shooting on the old Taoist's head. The old Taoist's scarred and dirty face was half-light and half-dark, which was really gloomy and terrifying.

"What are you, old man, who can close the door?" Dachun shouted.

The old Taoist sneered, "You know, I can't see some things here. If they shine, they will kill people. Do you understand?"

"Are you a ghost? You can't stand the light?" Dazhuang shouted.

Li Hui shouted in a deep voice: "Dachun Dazhuang, you can stay for me."

Dachun Dazhuang said in surprise: "Xiaolang, this..."

"Go out..." Li Hui said in a deep voice.

Dachun Dazhuang had no choice but to do anything. Xiaolang seemed really unhappy, so he had to bow and answer, turn around and open the door. Li Hui closed the door with his backhand.

Li Hui had already seen the situation in the house clearly. There were rows of wooden racks all around the house, full of jars, jars, dishes, and various wooden boxes to hold buckets. It seemed like he had come to a Chinese medicine shop to grab medicine.

The old Taoist looked a little surprised when he saw Li Hui kicking his two subordinates out of the house. He said in a deep voice: "It's okay for two talkative guys to go out. Mr. Li, the old Taoist is not talking nonsense. Some things in the jar here cannot withstand the light, the wind, and the water cannot be touched. Otherwise, a big thing will happen."

Li Hui smiled and said, "I understand. Some of the refined items here are very fragile and cannot be seen with light, hot water and wind, otherwise they will get heat, poison, and catch fire or disappear completely, right?"

The old Taoist exclaimed and looked at Li Hui in surprise.

"So you understand this."

Li Hui smiled and refused to answer. In fact, when the old Taoist said he was too shameful, Li Hui realized that there must be some unstable compounds and other things here. The old Taoist is a alchemist, and something might be produced in his room. He was from a science and engineering department, so don’t he understand that many substances in this world are unstable?

From this, Li Hui can also conclude that this Taoist priest is not a pretentious act.

After his eyes adapted to the light, Li Hui looked along the wooden racks. The wooden racks were marked with yellow paper. Although the things in the jars were invisible, the names could be known from the logos. However, Li Hui could not fully identify these substances from the name.

For example, you can still understand "red salt", "arsenic", "cinnabar", but you can completely not understand what it is.

While looking at these things, Li Hui secretly admired in his heart. Not to mention anything else, there are hundreds of substances on these racks. Whether it is minerals or refined compounds, the ones that can be placed on this rack must not be a ball of charred waste.

This ancestral not only lists the name, but also writes the color, shape, smell and some special traits on the paper. For example, "toxic, dizzy when smelled, and clear water can relieve it." "Red powder, spicy and pungent, burning when touched." It completely shows that these things were collected and displayed here after he screened and tested.

Although this Taoist was ugly and blind, he should not behave like a person. He was a real alchemist and an ancient chemist.

"Xiassian, are these things you have refined? It's amazing." Li Hui exclaimed.

"It is not entirely refined by the old Taoist. Some of them are just discoveries. There are about dozens of them that are refined by the old Taoist, and that is true." The old Taoist replied.

"That's also amazing. It's really amazing to refine so many new substances." Li Hui said.

"Hmph, what is this? There are more than a billion things in this world, and they are combined and divided, and they don't know how to exhaust them, just like the number of sands in the Ganges. Even if the old Taoist spends his life, it is probably difficult to refine more than a hundred. The mysterious world is not enough to exhaust them. What is this amazing? It's just a drop in the tank." The old Taoist said in a deep voice.

Li Hui was solemn and smiled and said, "When human power is exhausted, there is no way. But from generation to generation, there are people like Taoist priests. From generation to generation, one day, they will exhaust the principles of all things and find a combination of all things."

The old Taoist laughed and shook his head and said, "That's the case, but this is endless. The old Taoist thinks it is impossible to exhaust all things. Besides, how many are as obsessed with this matter as I am? Look at the alchemists in the world who practice killing medicines and cheat money and sex, which is completely contrary to the teachings of the Heavenly Master. With these people, they have not ruined the reputation of the alchemists of our Taoist sect. Such people are in power, let alone do everything in the world, even in the prehistoric times of the universe."

Li Hui had heard this old Taoist express his dissatisfaction with other alchemists several times, and felt strange. But now Li Hui was determined to find what he needed, so he didn't say much. He searched along the wooden frame, but he did not find the kelp he wanted. Because he didn't know if it was called kelp he was called kelp he was now, Li Hui had been carefully comparing the traits described on yellow paper. But none of them matched them.

Finally, after seeing all the things on and off the wooden frame, Li Hui sighed in disappointment, but finally found nothing.

The old Taoist had already developed interest and asked, "There is no thing you are looking for here?"

Li Hui shook his head and said, "No, it doesn't matter, this is also expected."

The old Taoist thought for a while and said, "There are still some smelting rooms behind, so why not look for them again. If the old Taoist can't find anything here, you don't need to look for anything else, there must be no."

Li Hui nodded, held the last glimmer of hope, and followed the old Taoist to another huge thatched hut behind. A huge stone stove was in the middle of the room, and there was no idea what to refine on the huge pottery pot. The stove was burning, and smoke came out of the chimney, which was exactly the smoke that the three of them saw on the hillside before.

There is also a row of wooden racks in the hut on the side of the smelting room. However, the wooden racks are all piled with ore. They are colorful and all kinds of them are available.

Li Hui looked over all the way, and suddenly, the words on the yellow paper label attracted him. The words "Shijing" were written on the yellow paper.

Li Hui hurriedly looked at the ore, which was light yellow, and was not very good-looking, and a small pile was piled up there randomly.

"What is this stone alkaloid...?" Li Hui asked in a deep voice.

The priest came over and said, "This is just a cold stone. Why? Is this what you want?"

Li Hui's mind was a sharp turn. It was obviously not the hula he wanted, but Han Shi himself knew it. It was a common name for a multi-hybrid compound. Most of the ingredients were carbonates. Li Hui had been changing his mind in the past few days. Since the hula was not found, it would be possible if there was a method to prepare it. With Li Hui's chemical knowledge reserve, he knew that there were several ways. The most effective one was of course electrolyzed salt water, but this was obviously impossible to achieve. The second was to react soda and lime water to get hula. Although the conversion rate was not high, it was a feasible method.

The sulphate in front of me is a natural mineral rich in carbonates, which contains a large amount of soda ingredients. Wouldn't this achieve the reaction to prepare sulphate?

Li Hui was extremely excited and reached out to grab a piece and looked at it carefully. He couldn't help but feel happy. He said, "I found it, it's this thing. I don't know where to get it? What's the price? Immortal, can I sell it to me?"

The Taoist priest said, "What do you want this thing to be?"

Li Hui said: "I can't tell you this. I'll pay for it. Also, can you tell me where I got it? I will definitely be paid."

The Taoist tilted his head and looked at Li Hui with one eye, with a strange expression: "If you don't want to say it, then the old Taoist will not sell it to you. How can you know that you are not using it to harm others?"

Li Hui smiled bitterly and said, "This thing is non-toxic and tasteless, how can it harm people?"

The Taoist priest was even more confused and said in a deep voice: "How do you know that it is non-toxic? You just didn't know what this thing is, and now you say it is non-toxic and tasteless. What are you going to do with this thing?"

Li Hui thought about it and finally said, "Immortal, I'm going to be invisible. I want to use this thing to prepare another thing called turtine. I'm very useful to turtine. But I will never use it to harm people. On the contrary, it's also beneficial to people. Please turtle Xianchang, sell me some, or tell me where to come. I've been looking for it for two days."

The Taoist priest suddenly became excited, grabbed Li Hui's hand and shouted: "Huo alkali? What is that? You must tell me. Is it a brand new thing? How to prepare this thing?"

Li Hui was shocked and was so scared by the rude behavior that he wanted to throw away his palm. But suddenly, Li Hui understood in his heart.

For this alchemist, his fun and all his interest is to smel and find new substances, understand their shapes and functions, etc. When he hears the emergence of a new substance that he has never seen before, it is like a glutton who sees delicious food, and a pervert can't help himself when he meets a beautiful woman. He is not rude, but it is difficult to suppress his excitement.

Li Hui pondered for a moment and said slowly: "Xiansheng, why not do this? I will prepare the kelp on the spot to let you know. Please tell me the source of the kelp. How about we exchange it?"

"Okay, okay, so good. Just a word is certain." The Taoist priest couldn't help but nodded repeatedly, looking as if he was afraid that Li Hui would regret it.

At that moment, Li Hui immediately began to prepare and built a simple fire platform in the backyard of the thatched cottage. He asked the master to set up the pottery basin. The materials needed were nothing more than lime water and stone alkali. These old Taoists used them here. Pour a can of lime water into the pottery basin, smash the stone alkali and grind it into the lime water, and the rest was the ignition and steaming solution.

The old Taoist was there and kept saying a lot. He was surprised by Li Hui's preparation method and was attracted by Li Hui's calm behavior. At the same time, he felt that these two things might not necessarily produce new things together, so he performed very strangely.
