Chapter 111: Resurrection Pill

……

The next day.

Just as Wu Wen was about to go out, he saw Goudan walking towards his door from a distance.

"Dog?"

Wu Wen took a few steps forward puzzledly and went to meet him.

"Brother Awen!" Goudan greeted with a smile.

"Why are you here?" Wu Wen asked.

"It was Master Jiu who asked me to come find you." Goudan replied.

"What happened?" Wu Wen asked immediately.

"No, nothing happened. It was Jiu Ye who asked me to come find you and ask you to go back." Goudan said.

"It's good that nothing happened!" Wu Wen nodded in relief, and then asked again: "Master Jiu asked me to go back, is there something wrong?"

"I don't know either. It was Master Jiu who asked me to tell you to go back quickly. He seemed very happy and anxious." Goudan replied.

"Is it urgent?" Wu Wen heard this and said, "Then there is no time to lose. I will go back with you now."

He turned around and went back into the mansion and led the horse out.

"Young Master, where are you going?" Fugui asked in confusion when he saw Wu Wen leading the horse.

"I'll go back to Zhujia Village and take a look. I'll be back soon."

After responding, Wu Wen took Goudan and left Chang'an City.

After speeding all the way, they soon arrived at Zhujia Village.

When they arrived outside the courtyard, Goudan ran forward first and opened the gate.

Wu Wen entered, leading the horse.

At first glance, I saw Jiu Ye seemed to be fiddling with something in the yard.

"Awen, you're back!"

Seeing Wu Wen, Zhu Jiuye came forward excitedly.

"Look, look what I got."

Master Zhu Jiu took out a piece of paper from his arms and handed it to Wu Wen to look at.

Wu Wen took it and read it, and found that it was a prescription called "Huan Yang Dan".

After reading all its contents, Wu Wen discovered the differences.

The reason why the pill on this prescription is called Huanyang Pill is because it has the effect of restoring yang and rescuing the patient.

Restoring yang to save the patient is a first aid technique.

Yang Qi is the most important force for human life activities. It warms the organs and tissues throughout the body and maintains the normal functions of the body.

When the human body is attacked by evil cold or its Yang Qi is severely damaged due to other reasons, critical symptoms such as cold limbs and weak pulse will appear.

At this time, it is necessary to adopt the method of "restoring yang and rescuing the patient" to restore the normal function of yang energy in order to save his life.

This kind of first aid is a secret technique that ordinary doctors don’t know at all.

Moreover, this kind of first aid is very difficult, because those who need to be saved are people who are in desperate situations and on the verge of death, or even people who have already died, so all of them are unconventional means.

Without sufficient experience and extremely advanced medical skills, this kind of first aid may accelerate the patient's death or make his death more complete.

And this elixir called Huanyang Dan is actually said to have the effect of restoring yang and rescuing the dying, so this elixir is a miracle drug.

"How is it? Isn't it amazing?"

After seeing Wu Wen finish reading the prescription, Master Zhu Jiu said excitedly.

"Yeah!" Wu Wen nodded in response.

"The reason why I asked you to come back is because I want you to work with me to refine this yang-returning pill."

Master Jiu said: "As long as we can refine it successfully, we can save countless lives and leave our names in history." Seeing Master Jiu's excitement, Wu Wen understood why he was so eager to call him back.

"Master Jiu, don't get too excited. Whether this elixir really has the effect of restoring yang and rescuing the patient still needs to be verified. I will help you study the prescription first." Wu Wen said.

"It must be true!"

Master Zhu Jiu said firmly: "I have read this prescription several times. As long as the elixir can be refined, it will definitely have the effect of restoring yang and rescuing the patient."

Wu Wen looked down at the prescription in his hand again:
'Put ten pounds of sulfur in a copper pot and boil it. After filtering it with linen cloth, pour the sulfur liquid into water, then boil it again and pour it again. Repeat this seven times.

Then grind the sulfur into fine powder, put it into a ceramic jar, tie the lid tightly with wire, seal the outside with salt mud, and then dry it in the shade.

First, use a slow fire to calcine the pot until it turns red, then increase the heat and continue calcining.

After that, the furnace is allowed to cool, the jar is removed and buried in the ground for three days to remove the fire poison.

Finally, grind the sulfur into powder and make it into balls with the steamed cakes, the size of sycamore seeds.

Although the method of refining the Huanyang Pill was clearly written on the prescription, Wu Wen believed that it lacked the most important thing, that is, proportion and data.

It's like cooking according to a recipe. The process seems simple. Just heat the oil in a pan, put the side dishes and main dishes in one by one, then pour the seasoning on them and serve.

But the dishes prepared in this way will taste different for each person.

Some people's food is particularly delicious, but some people's food is not delicious. It is either raw or rotten, too salty or too bland.

The reason is that when cooking, a series of parameters such as heat, oil temperature, amount of seasoning, etc. are different.

Similarly, the refining process of the Huanyang Pill is the same.

Its main ingredient is sulfur.

Sulfur is a highly toxic substance. If it is not handled properly, it will not be a medicine but a poison.

Also, if the refining method is too radical, not only will the toxicity of the sulfur be removed, but its medicinal properties will also be removed, and the refining will be in vain.

Master Zhu Jiu pulled Wu Wen to the pile of things he had just been fiddling with, pointed at them and said, "Look, I have everything ready. We can start refining as soon as you come back."

Wu Wen looked down at the pile of things on the ground: sulfur, medicine grinder, mortar bucket, linen... as well as pottery jars and copper pots.

Wu Wen immediately noticed something wrong. The copper pot prepared by Master Zhu Jiu was made of red copper.

Although red copper is pure copper, its properties are not stable. Under high temperatures, it easily reacts with sulfur and is corroded by it, seriously affecting the effect of the boiling process.

Therefore, in Wu Wen's opinion, it is more appropriate to use a brass pot.

Brass is an alloy of copper and zinc. It is stable and does not easily react with sulfur.

Then, Wu Wen pointed at the copper pot on the ground and said to Master Zhu Jiu, "Master Jiu, this pot needs to be replaced with a brass one."

"Why?" Mr. Zhu Jiu asked back.

In his opinion, since the prescription says a copper pot should be used, a pure copper pot should be used.

"because……"

Wu Wen was about to explain it, but he suddenly thought of a question.

Nowadays, the price of copper is not low. It can be seen from the copper coins used in daily life that copper is equivalent to currency and even exceeds the value of currency.

The reason is that copper coins are not made of pure copper, but are mixed with other metals such as lead.

How much would such a large copper pot cost? With Zhu Jiuye's ability, how could he possibly afford it? And where could he buy it?

Thinking of this, Wu Wen immediately asked Master Zhu Jiu in a serious tone, "Master Jiu, where did you get this copper pot?"

"Also, where did the prescription come from?"
