"So this is the only way you can manually prepare the 'holy water' you mentioned?"

Lin Hai looked at Wang Maoduan in front of him and could tell that he was a little angry. This so-called "holy water" was actually dilute sulfuric acid rich in various impurities produced during the alchemy process.

Wang Maoduan was a lucky man. Since Lin Hai had once asked everyone to pay attention to all kinds of strange people, everyone was particularly concerned about those who claimed to have all kinds of superhuman abilities. Qinghe County Government had also posted a notice to recruit all kinds of strange people. At one time, countless people signed up, and the whole Qinghe County Government was in chaos. After seeing people fishing out keys from a frying pan with bare hands, turning water purple-red by touching it with their hands, and all kinds of people who said they could pray to gods to possess their bodies and become invulnerable to swords and guns, Lin Hai gave up the idea of ​​finding the talents he wanted by posting notices.

After all, people of this era simply cannot find the dividing line between science and superstition. Even if someone may master the chemical properties of a substance due to some coincidence, he will probably regard this as a miracle and use it to cheat money instead of conducting research on it. So instead of recruiting people with great fanfare and causing chaos and making people lose interest in production, it is better to send people to conduct secret investigations. After all, anyone with this technology will definitely come out to cheat money. So as long as they hear that some genius has appeared somewhere, they will just send people to capture him and that's it. Even if they catch an incompetent person, they can treat him as a liar.

Of course, when the man who claimed to have trained a pair of iron palms that were not afraid of the oil temperature finally put his left hand into the oil pan without vinegar to fry the meat, and the man who was blessed by God to turn water purple and cure diseases washed out the last bit of potassium permanganate from his fingernails, Lin Hai had lost his patience with the invulnerable man and just ordered: "Shoot him with a light crossbow. There will be a bonus if he survives." The guy collapsed to the ground and was unwilling to get up for a long time.

Now they have all become glorious lifelong workers in the Qinghe Industrial Park. Well, one of them even contributed the formula for potassium permanganate, so his treatment will be slightly better, at least he doesn't have to pour molten iron.

Although Wang Maoduan was always hiding his secrets and being hesitant, everyone knew how he did it after seeing him prepare the so-called "magic water" twice. Moreover, Lin Hai was not interested in this kind of "production" that had no scientific management at all and could be completed only by experience and steady hands.

After confirming the method for preparing sulfuric acid, Lin Hai said casually, "It doesn't look like much. There's probably no point in you staying here."

A smile of freedom immediately appeared on Wang Maoduan's face, then quickly faded away. Cold sweat visibly emerged from his forehead and quickly covered his entire head.

Wang Maoduan vaguely remembered hearing people say when he first came here that there was a ruthless elder brother with an iron hand, who was defeated by the "Lord Lin" in front of him because he contributed the recipe. Half of his arm was blown into crispy meat, and now it is said that he is still doing hard labor with one hand.

Thinking of this, Wang Maoduan gritted his teeth and squeezed out a smile that was uglier than crying: "Master Lin, this\u0027holy water\u0027..."

"From today on, this substance will be called sulfuric acid."

"Yes... yes..." Wang Maoduan didn't know why this thing was called "sour". Lord Lin had never tasted it. It was really a quirk of a big shot. However, he really didn't know whether this thing was sour or not. He would try it when he had time.

"Sir Lin, this sulfuric acid will surely be of great use to you. I am responsible for refining pills in the temple. I can make all kinds of pills, and this sulfuric acid is just one of them. If you are interested, please let me and my fellow disciples go. We will not go back anywhere. We will definitely refine pills for you here. If you take it yourself, you will not be able to achieve immortality, but at least you will live longer. It will also be a great gift to the high officials in the capital." Wang Maoduan knew that he had few opportunities, so he explained his value clearly in one breath.

"Well, about alchemy, let me ask you, how many Taoists who can make alchemy do you know? I'm not talking about the three cats and two dogs in your Youxian Temple. I'm talking about the major Taoist temples in the world. How many Taoists who can make alchemy do you know?" Lin Hai asked.

Seeing Lin Hai's intention, Wang Maoduan quickly said, "Originally, all the major Taoist temples in the world have Taoists who study elixirs. After all, taking elixirs to strengthen the body is a common sense passed down for thousands of years. If you really understand that level, it is not impossible to refine the elixir of immortality. It's a pity that a few years ago, during the Four Kingdoms War, those in my Taoist sect who knew some medical skills, many brothers and sisters were captured and sent to the army by various countries, and their alchemy furnaces were melted down for money. The Youxian Temple where I live was not originally in Xichuan, but on a small hill south of Zhongnan Mountain. It was to avoid the war. When I was young, my master moved the entire temple to Xichuan to avoid the war. Who would have thought, alas..."

"Oh." Lin Hai was not interested in such tragic stories at all. If he wanted to hear tragic stories, he could go to those refugees who had just come down the mountain, those women who were rescued from the mountain village and saw the sun for the first time in several years and were covered with ulcers, and those slaves who were locked in the mill and forced to grind the ground by the mountain king until they died without a single piece of good meat on their backs. As for a Taoist temple, it was able to move thousands of miles safely and even moved an alchemy furnace weighing thousands of kilograms. Lin Hai felt that this was not a tragic story, but at most a travel story.

"I want purer sulfuric acid. You know how many impurities are in it. I want you to find a way to remove them. You can figure out the method, but if you can't do it within ten days, put yourself in the furnace and refine it yourself to save me the trouble. If you do succeed, I have a plan for the next step, and I'll come to you then."
