If a mortal wants to extract the spiritual energy from the spirit stone, he must first remove the skin of the spirit stone. Since the spirit stone becomes alkaline, he peels it through hydrochloric acid.

In this era, there was no hydrochloric acid but there were many salts, so the method of electrolyzing concentrated brine must be used to make hydrochloric acid.

Someone will definitely ask, where do you come from? This is obviously not difficult for Wu Zhen. He directly used simple human power generation: made a bicycle with wood, and an iron rod passed through the center of the rear wheel. The iron rod and a square iron frame kept turning between the two magnets.

The chlorine and hydrogen produced by electrolysis are synthesized into hydrochloric acid and introduced into the high-temperature boiled spiritual stone pond. Not only does it dissolve all the stone skin, but it also leads the spiritual energy through bamboo tubes.

At this time, the derived spiritual energy contains water vapor. In order to ensure the purity of the spiritual energy, Wu Zhen cooled the mixture of spiritual energy and water vapor to condense the water vapor into water. In this way, the extraction of spiritual energy is completely completed.

After the spiritual energy is exported, it is dried by limestone and is absorbed by the talisman paper. This high-purity spiritual energy makes all the coins produced at the best grade level.

Wu Zhen divided the entire production process into dozens of steps, each step is separated by a wall, so that the employees engaged in it cannot know the manufacturing process.

Coins are endless, and because of the good work of confidentiality, they have not attracted the covetousness of other cultivation sects, which gives heaven enough time to develop.

Three years passed by, Wu Zhen was nearly ten years old. Paradise has undergone earth-shaking changes in the past three years. Wu Zhen simply moved the Great Leap Forward of the Earth here.

The former Long Xiao Hall was built into villas by him. The originally bumpy mountain road was converted into a mountain road by him, and the barren mountains and wild ridges were opened into breeding farms and processing plants!

The most outrageous thing is that Wu Zhen directly used the coins as dark paper and scattered them on a small hill!

The expenses and the salaries of the disciples in the hall are all collected by whoever is short of them.

At first, some disciples thought that this had trampled on their self-esteem, but seeing that others were so happy, now they don’t even want moral integrity, so what about self-esteem?

If someone can see the current paradise, he will definitely suspect that it is another world! Because in such a non-technical era, paradise is really paradise!

"What are you doing?" Ye Siyu asked when he saw Wu Zhen squatting on the ground and fiddling with a square wooden stick that was being peeled.

In three years, she has witnessed too many miracles, such as greenhouse planting, ecological breeding, and coin processing... Now she has long been close to Wu Zhen.

Yiren was wearing white clothes and black hair was like a waterfall. She didn't mind the slightest slight spring light on her chest. She faced Wu Zhen and spoke with her ears.

Wu Zhen was very helpful and said happily: "In the past three years, I have not only refined my cultivation to build the foundation, but also carefully studied various alchemy techniques. After you are the Dan King, you should know how important the material matching is to alchemy!"

"The material ratio is the soul of alchemy. If you don't understand the key points, then it's like a waste of resources like traditional Chinese medicine!"

"That's right, every time I roll my wooden stick on the bottle, it's 1ml. ml is a unit of measurement. I can use this bottle with unit to dispense medicine to ensure the accuracy of the ratio!"

Ye Siyu is very smart and can understand it at first glance. Although she is not from the same era, he never needs to explain Wu Zhen's words again, which is why Wu Zhen loves her so much.

"Yes, why is such a simple thing? No one thought of it before. My father always refines elixirs based on experience. If he has such a bottle, the heat will be much easier to control!"

"Yes, the reason I started making these bottles is because I was going to start producing elixirs."

"You really know how to refine elixirs? My father's true teachings are all here with me. Unfortunately, I am obsessed with music theory and medical skills, and I know nothing about elixirs..."

"It's okay, just have me. I'll refine whatever elixir you want!"

Ye Siyu's cheeks were slightly red. Now she no longer regarded Wu Zhen as a child. Wu Zhen was the only one who helped her when she was in a downturn. From the moment she was sealed off, she had already regarded her as the only one.

"Come with me, I'll give you all my father's alchemy experience."

"No, I don't want the experience of alchemy, I just want the formula." Wu Zhen is a person who has passed through the technology era. His intelligence and knowledge are far beyond this era, so he does not lack any experience, he only needs the formula. As long as he has the formula, he is confident that any pill can be refined in his own way.

"Okay, come with me." Ye Siyu took Wu Zhen to a study room. The room was covered with bookshelf, and the bookshelf was neatly filled with bamboo slips. After the baptism of time, the intoxicating fragrance of books was emitted.

If no intellectual person doesn't like books, Wu Zhen picked up the book and read it like a child caring for toys, regardless of whether Ye Siyu is still by his side.

Nearly ten thousand bamboo slips were read by him in just half a day. Ye Siyu has been by his side. It is said that serious women are the most beautiful, but serious beauty does not distinguish between genders. In Ye Siyu's opinion, Wu Zhen, who is reading books, is the most charming moment in his past few years.

"You have finished reading all of them. Is it useful to read books like this? If you just want to read these books, it's meaningless."

Wu Zhen raised his eyebrows and said in a teasing tone: "Come on, pick a book and test whether I remember it."

"You are really excited! Let's hear the recipe for Qingshen Pill."

"One concentration grass, ten passion fruits, two Cheshan flowers, two Shibuya roots, and one pound of dried sealed skin."

Ye Siyu was a little surprised. He was right! He must have happened to remember this recipe only.

"What is the formula for Soul Reincarnation Pill?"

"A flower protecting the soil, a sacred grass, and seven leaves that kill the soul."

This time Wu Zhen was right again. Ye Siyu didn't give up and asked dozens of elixirs in one breath, but Wu Zhen answered happily.

"Is there really such a genius in the world?" Ye Siyu thought to himself.

"How did you do it? Have you seen all these prescriptions?"

"I am born with cleverness and can never forget everything!" Wu Zhen still used his eyes when he spoke, as if he was awesome but very troubled.

"You are proud. Don't think that memorizing a few prescriptions will make you invincible in the world. Being an alchemist is not an easy task. Do you have a alchemy furnace? Can you attract earth fire? Can you purify it? Can you..."

Ye Siyu's series of questions made Wu Zhen beat him up. He supported his forehead and said, "How can he be a man?"

"Then can you have a bridal chamber with me?"

Wu Zhen: "..."

Afterwards, Wu Zhen looked at his underdeveloped little brother while taking a shower: "Little Chicken, you should grow up quickly!"
