Go to the gate of Qingfeng Temple and entrust the horses to the care of a nearby shopkeeper. Qin Feng found a Taoist, and it happened that the Taoist knew Qin Feng, so he took the two of them to see Wang Zhenren.

Wang Zhenren got the report and came out to greet him in person. As soon as he saw Qin Feng, he saluted and said with a smile: "Qin Gongzi, you have gained fame and fortune in the past few days, but you have forgotten my birthplace?" ”

Qin Feng returned the salute and replied with a smile: "Feng doesn't dare, but it's Wang Zhenren, who hasn't seen him for a few days, and his spirit is even worse." ”

"Haha, Qin Gongzi went to my two heart problems, and my mood is naturally much better. Qin Gongzi is here to get the silver? ”

"No, Kaede has another matter."

"Oh, what's the matter?"

"I heard that there is a master of paper-making, and the magnetic green paper made by the temple cannot be compared. Kaede really wants to meet this master, please ask him to make some paper, I don't know if it's okay? ”

Wang Zhenren nodded and said, "What you are talking about is my junior brother Chang Shouren, who is good at alchemy. I also like to use secret methods to make rare things such as magnetic green paper. ”

Qin Feng was happy in his heart, a Taoist priest of Dahua and an alchemist of an exotic land. He was the world's first chemist. They are the most valuable talents in this era!

Wang Zhenren continued: "But my junior brother is not in Qingfeng Temple, he lives in the back mountain. It's five or six miles away from the mountain road, and if you want to see him, you have to follow me to the back mountain. ”

"Thank you Wang Zhenren!"

Wang Zhenren took an entourage, and the four of them meandered along the rugged mountain road.

The group walked on the mountain stream path.

Look up at the towering trees, bow down and gurgle the stream. Occasionally, the fragrance of flowers floats, and birds sing to welcome and send off. A few wisps of fresh breeze caress the face, and a cool feeling refreshes the spleen.

Qin Feng praised: "Walking here is really refreshing. ”

Wang Zhenren said with a smile: "The mountain road is quiet, and when you are in a bad mood, coming here for a walk will relieve you a lot." Wang Zhenren raised his hand and pointed in another direction and said: "From that place up the mountain, there are many warm pools along the way, which dispel dampness and detoxify, and go to fatigue and wake up the brain, which is quite effective." Qin Gongzi has time, you can try it. ”

"No wonder, Rihai and Lee Chang-hyuk didn't leave as soon as they came here!"

"Haha!"

......

Bypassing a lush greenery, Qin Feng's eyes suddenly brightened.

In front of you is a recess between two mountain peaks, although it is a recess, but the terrain is wide and the view is vast. The grass is green everywhere, and wildflowers can be seen everywhere.

You can see that this place is often taken care of.

Several rows of bluestone houses, neatly laid out in several columns. A gray-clothed Taoist man hurriedly stepped forward and saluted Wang Zhenren: "I have seen the master." ”

"Where's your master?"

"Master is in the courtyard, please come with me."

The group walked into the courtyard of the house, a middle-aged Taoist priest, sitting on a chair, with a set of tea sets placed on the stone table in front of him, it was Wang Zhenren's junior brother, Chang Shouren was pouring himself a drink.

"You're going to enjoy it!" Wang Zhenren said loudly as he walked.

Chang Shouren looked sideways when he heard the sound and beckoned: "Come, come!" Taste my cloud mountain green buds. At this time, it is best to drink tea, the mountain spring water wakes up, and everything recovers. By noon, it was a bit hot. ”

"What are your clouds, mountains and green buds, what you eat and drink here, I sent it to you!" Wang Zhenren sat down unceremoniously, and beckoned Qin Feng to sit down together. Then he turned his head to the Taoist who led the way: "You take Jia Song around and entertain him well." Qin Gongzi and I, talk here. ”

Chang Shouren took out two empty cups with a bamboo clip in his hand, placed them on the wooden table of the tea set, picked up a pot of boiling water, and poured it from the mouth of the cup. While warming the cup, after listening to Wang Zhenren's instructions, he replied: "What is placed here for me is my Yunshan Biya." This Qin Gongzi, but Qin Gongzi who retreated from Dongying Goryeo chess players? ”

Qin Feng said with a smile: "Exactly, Qin Feng heard that Chang Zhenren has paper-making skills, and Feng Te came to pay a visit." ”

Chang Shouren poured boiling water into the teapot again, and a trace of fragrance rose. Chang Shouren pressed the tea lid with his hand and said with a smile: "I am the Taoist of alchemy." He is the real person, and the imperial court enshrined Yuyang as a real person. Chang Shouren said, his chin raised towards Wang Zhenren, and then said: "As for papermaking, it is a small skill, what a worry!" ”

"This is no small skill!" Qin Feng said: "Poetry can express feelings. The Four Books and Five Classics can promote morality and have the concept of governing the world, only that. And Chang Daochang's so-called small skills at the end of the branches can go up to the moon for nine days and catch turtles in the five oceans. Even, time and space shift, turn things around! This is no small feat! ”

Chang Daochang arranged the three teacups in a row, lifted the teapot with his fingers, moved back and forth above the three teacups, evenly and slowly poured the tea, and poured the three cups until they were eight points full.

Chang Shouren first took the teacup he had used in front of him and made a gesture: "Please." ”

Wang Zhenren stretched out his fingers, gently pinched the upper edge of a tea cup, brought it to his lips, and tilted his head slightly.

Qin Feng has a good example, the tea cup is under his nose, exuding wisps of fragrance, try the temperature, take a sip carefully, not bad! As soon as I drank it, a slight astringency entered my throat, and there was a hint of sweet aftertaste.

Chang Shouren put the empty cup on the table again, and while refilling the tea, he said: "Go to the moon for nine days, and catch turtles in the five oceans." Time and space shift, turn things around! That's what my senior brother can only do after he becomes an immortal. Qin Gongzi, you praised the wrong person. ”

Wang Zhenren was slightly embarrassed: "I cultivate the Dao Law and conform to the will of heaven." Don't dare to expect the flying immortals to become gods. I can't do any of these things. ”

Qin Feng smiled bitterly and shook his head, without explaining, and asked, "Dare to ask Chang Dao people who have been alchemizing pills for many years, but they have encountered some strange things?" For example, some things change when heated. Two things merge into one and become the other? An inexplicable explosion? The water that can make gold disappear? ”

Chang Shouren's hand shook, and a teacup overflowed. It happened to be the teacup that Qin Feng had used, Qin Feng stretched out two fingers, picked up the teacup and tilted it gently, overflowing two points of tea, and then brought it to his mouth, shaking his head and blowing gently.

Now the Taoist leader of alchemy is gradually being abandoned by the mainstream of society. Because more and more people are discovering that the so-called golden pill is actually harmful to the body. Therefore, even the Taoist of alchemy is called a liar and a god. This industry is being marginalized.

The Taoist who has been alchemy for many years has made many discoveries in the field of chemistry. Because there is no detailed record, no economic value has been discovered, and what is done is not recognized by the world. Therefore, even if he really likes the change of material reactions, he will not be able to persist in long-term research.

Chang Shouren is lucky, he likes these things and likes to study. The important thing is that he also has a senior brother who can provide silver support, so he can always insist on doing his own research in the name of alchemy.

The magnetic green paper was made by Chang Shouren himself.

But the senior brother was willing to give him money to provide for his daily necessities. is because the two are brothers and have a deep relationship. As far as things are concerned, Wang Zhenren does not agree with his approach.

Although Chang Shouren used magnetic blue paper, he proved his research value. But it's worth showing off, and that's the only thing that can be converted into silver taels, so he is still not recognized.

In this regard, Chang Shouren is alone.

Now that he was suddenly recognized by Qin Feng and given such a high evaluation, Chang Shouren was a little excited. There is the excitement of dying for a confidant.

Happiness came too suddenly. Chang Shouren was worried that Qin Feng would fool him.

So Chang Shouren stared at Qin Feng seriously and asked, "What Qin Gongzi said is serious?" ”

Qin Feng nodded seriously: "Chang Daochang's research is indeed very human!" It's just that it's still in its infancy, and it can really change the world in the coming years. ”

"What has changed into?"

Qin Feng hesitated: "I don't know, but it's definitely getting better and better." I can't explain too much, so let's do it one thing at a time, and then we look at what will change, how? ”

"We? Qin Gongzi wants to follow me to practice? ”

"That's right! But I only have ideas, and I can also give money. ”

"Thoughts? How do you say that? Silver? What's the point? "You can talk nonsense in your mouth, but if you are really willing to give money to support yourself, then this Qin Gongzi will not fool you.

Qin Feng said: "Qingfeng Guan now has 10,000 taels of silver deposited by me, and Chang Dao Chang can use it." In a few days, I will be able to send another thirty or fifty thousand taels of silver. After that, as soon as I have any money, I will send it. ”

Wang Zhenren's face changed.

Chang Shouren was also stunned: "Is this true?!" ”

Qin Feng said with a smile: "It's true, if there are other Dao Masters who are experienced in alchemy, Chang Dao Masters can invite them as well." In the future, I will earn more silver and send it to me. We will not let everyone worry about money. ”

"Why are you?"

"Don't you don't believe what I just said, then let's try it together and change the world."

Chang Shouren said with a straight face: "Gongzi Qin, have you thought about it?" ”

Qin Feng said with a smile: "I also have a few requirements, and the research direction is formulated by me." For example, now, please study two things, one is a kind of paper, which is not afraid of soaking in water for a short time, and it can be played in your hand, which can make a noise and be folded many times without damage. The second is that in addition to gunpowder, there is something else that can explode, and the power is even greater than that of gunpowder. ”

Qin Feng paused for a moment, and then said, "Besides, when Chang Dao Chang is researching, he must pay attention to safety. Only when people are okay can they do research and see how the world passes through your hands and changes. ”

Chang Daochang nodded silently, and his mood was uneasy for a while, and he didn't even have the mind to pour tea.

Wang Zhenren looked at Qin Feng: "Qin Gongzi really thinks like this?" ”

Qin Feng nodded and said, "I still have to bother Wang Zhenren and send 10,000 taels of silver for the use of the Chang Dao Chief." ”

Wang Zhenren nodded.

Qin Feng said again: "Chang Dao Chief, when you do research, please make sure you make a record." ”

Chang Shouren said: "This is nature. We alchemists have been taking notes all the time. ”

Qin Feng shook his head and said: "To record accurately, for example, three feet is one meter, one meter is divided into ten sections, each section is one decimeter in length, one decimeter is divided into ten sections, each segment is one centimeter, and centimeters are divided into ten sections, which is millimeters." Weight, one tael of silver is ten grams...... Water, water-like, in liters...... Uniform and precise length, weight, and capacity are the most basic ......"

Chang Shouren was stunned: "Gongzi Qin, have you also studied alchemy?" ”

"No, but I know something. For example, the paper I just mentioned, Chang Daochang can use sawdust, coarse cotton, etc., put it in the ding, and heat it to cook ......, such as explosives, with nitrate, glycerin, glycerin can be extracted in this way......"

Qin Feng reminisced about high school chemistry while telling the story.

In the Dahua era, many substances have been discovered, but the alchemists did not systematically study and communicate with each other, so they lacked a qualitative breakthrough.

If you want to invent something that doesn't exist in the world, it's a thousand difficulties.

But what is already in the world, you just need to pierce this layer of window paper, and you can quickly imitate it.

Qin Feng didn't want Chang Shouren to take another detour, so he explained in detail all the formulas and dangers he could think of.

Wang Zhenren and Chang Shouren listened attentively, and occasionally had doubts, and Chang Shouren would also ask some questions. Qin Feng said in his mouth

Chemistry knowledge, as if his heart is slowly returning to the past life, he is using the university vacation to tutor middle school students in chemistry.

Wang Zhenren beside him, Chang Shouren on the other side, looked at Qin Feng's eyes, and they were also slowly changing......

"However, in addition to safety, you must also keep it confidential." Qin Feng moved the tea procedures by himself.

Chang Shouren said: "The world thinks that I am in alchemy, and this place is the industry of Qingfeng Temple. Idlers can't get in. On weekdays, I do everything in the Yunshan Canyon, you can come and see. ”

The three of them got up, and Chang Shouren took the lead, and walked to the edge of the deep meadow, and when they reached about two hundred paces, a canyon appeared in front of them, in which several stone houses were built.

Chang Shouren pointed to the canyon and said: "This is the intersection of the two mountain veins, the sides are steep, difficult to climb, the only place to go down is here." Deep in the canyon to the cliffs, there is no way to go. However, along the direction of the canyon out of the mountain, you can go out for three or four miles. It was the only way into the valley except for me. ”

Wang Zhenren continued: "Go out and take a few hundred steps around, which is where the side gate of my Qingfeng Temple is located, and the few families living in Gukou are also tenants under the name of my Qingfeng Temple. Senior Brother Chang made a movement here, and only those few families could hear it. Later, I arranged to give them a bigger and better piece of land to cultivate. That place ......"

"Just sell it to me, I'll build one there, the Wenchi Annex, guard the valley mouth for the Chang Dao Chief, and I can also consult with the Dao Chief from time to time." Qin Feng said.

Wang Zhenren nodded and said with a smile: "Living next to Gongzi Qin, I can't ask for it." Don't talk about buying it, give that piece of land to Qin Gongzi. ”

Qin Feng was so generous to Chang Shouren, Wang Zhenren couldn't be stingy, and fell into the name of Qingfeng Temple.

After this exchange, a preliminary cooperation was formed, and the relationship between Qin Feng, Wang Zhenren, and Chang Shouren felt much closer.

In particular, Chang Shouren even introduced Qin Feng as a confidant.
