The Demon Slayer Martial Saint Begins with Insect Refining

Chapter 40 Burning Pain
Su Yan followed Xu Zhongdao into the alchemy room and saw a pitch-black alchemy cauldron.

"First, sort the herbs by category and lay them out. Then I'll see how I deal with them."

As Xu Zhongdao spoke, he changed his clothes and tied up his hair completely.

"When I was refining the Yi Jin Xu Mai Wan, I needed to concentrate on controlling the cauldron, so I needed someone to help me. I could have asked Bai Cao Tang or asked Old Song for help, but I was worried about someone interfering, and I was also worried that he would get excited."

Song Qi had entrusted Su Yan with the task of teaching him some skills, but the key point was to refine the Yi Jin Xu Mai Pills.

Su Yan arranged the herbs according to Xu Zhongdao's instructions.

"Mr. Xu, the herbs are ready."

He turned around and immediately showed a look of surprise.

Xu Zhongdao actually lay there and lit the fire. The charcoal spread under the furnace, and the flint was emitting flames, igniting the charcoal.

Seeing him like this, Xu Zhongdao chuckled and said, "Why, do you think refining medicine is so profound and unfathomable?"

Su Yan didn't know how to answer for a moment, and said, "I think it might be a little more magical. I really haven't thought about it this way."

"That's a high-level elixir."

Xu Zhongdao threw the flint aside and fanned the charcoal fire to make it burn more vigorously.

"High-level elixirs are not only made with true essence, but also incorporate the true meaning of beast spirits. Adding the essence of heaven and earth, they have the power of creation. However, those are only made by masters of the upper sects like the Beast King Sect and the Danxuan Sect. Most of them are above the third level."

"Is that so? But this makes sense. The first three realms of the Body Tempering Realm cannot even cultivate true essence, so it is naturally impossible to be as imagined."

"Mr. Xu, these are the requirements for levels three and above, what about levels one and two?"

"Hey, isn't the first level right here?"

"Alchemy with ordinary fire is called alchemy, but it is more accurate to say it is medicine."

Xu Zhongdao threw the Yin Chigen into the alchemy furnace and then controlled the size of the fire.

"So-called first-level elixirs utilize the medicinal properties of various herbs to combine with each other. Through boiling, roasting, grinding, and mixing them into a medicine, they can stimulate medicinal properties that surpass those of the herbs themselves."

Xu Zhongdao was already very familiar with alchemy. While he was guiding Su Yan, he had already dried the Yin Chi root a little.

"Watch it."

Then he threw some medicinal herbs into it, forcing out the juice and mixing it with the Yin Chi root.

"Matching medicinal properties, neutralizing toxicity, and stimulating medicinal power are the fundamentals of medicine refining. This is especially true for first-level precious medicines, which cannot be sorted and guided by true essence entering the cauldron."

"What about the second level?"

"The Yang Yuan realm can nourish the true essence. Once the true essence leaves the body, it can enter the cauldron to harmonize the medicinal properties of the elixir, guide the furnace fire, and greatly increase the efficacy of the medicine. This can be called a second-level elixir. If it is the true meaning realm, it can be integrated with the true intention of the beast spirit. The effect of the elixir will naturally be even stronger, and it can be considered a true second-level elixir."

Xu Zhongdao picked up a few more herbs and added them in, saying, "Yi Jin Xu Mai Wan can be considered a barely second-grade elixir, but it's also the weakest of the first grade."

Su Yan was moved by what he heard and thought to himself: "If the Yinshui centipede and the Velvet Fire Scorpion swallow the elixir, I think they will make faster progress."

Xu Zhongdao stopped talking. As more and more medicine was added, the fire in the furnace gradually went out. He took out the dry medicine, put it in the grinding tool, and started grinding.

After about half an hour, two bottles of dark red powder were finally ground.

"Take it and try it. I'll see what you can handle so I can make adjustments."

Su Yan took the specially made Red Skin Powder. Although the quantity was smaller, the price of these two bottles was twice that of the Red Skin Powder sold by Baicaotang.

Su Yan thanked Xu Zhongdao again. The two of them left the alchemy room and without resting, went straight to the backyard to try the effect of the Red Skin Powder.

When I arrived at the yard, Song Qi was standing in the yard.

The green robe on his upper body had been removed, revealing a strong body covered with scars. Although he was old, his body had more wrinkles.

But this body of angular muscles, the surging blood and the roar like thunder are as mighty as Qingyang opening the mountains.

"The Great Achievement Stance, this Qi and blood is the Qi and blood of the Moving Blood Realm, like a long river."

Su Yan noticed out of the corner of his eye that there were two large wooden vats placed here, one of which showed signs of having been used.

The medicine residue scattered, emitting a very faint medicinal fragrance. Xu Zhongdao was preparing for Song Qi's injury, and Song Qi himself was also constantly activating his body meridians and making continuous preparations.

Song Qi stopped when he noticed the two people coming in.

"Boy, that bucket over there is yours. The servant will heat some water for you."

Su Yan nodded and strode over. The servants had already added several buckets of hot water into the pot.

The specially made red skin powder was added in, and in an instant the entire large wooden vat turned red and almost boiled over.

Before Su Yan entered, he felt a fishy, sweet, spicy wind accompanied by heat.

"This stimulation is probably several times stronger than this red skin powder."

"Boy, what are you waiting for? The inner gate examination of the Golden Ape Martial Arts School is not long."

Xu Zhongdao didn't know whether he wanted to watch the fun or see how talented Su Yan was.

Su Yan did not hesitate and took off all his clothes except for his shorts, revealing his well-defined muscles. His bones, skin and muscles looked like a perfect model.

He entered the barrel and quickly submerged his entire body in it.

In just a moment, it felt like flames were burning his skin. Even though he had mastered the art of skin refining, he still felt severe pain all over his body.

"It hurts so much, even a master of the Body Refining Realm couldn't resist it."

Su Yan's face changed. Great pain swept through his skin, making his face look extremely ugly.

Veins popped out and his body began to show damage from being eroded by the drug.

'Golden Ape Posture!'

The intense pain was like an endless tide, sweeping over every inch of his body.

The medicinal power, mixed with toxicity, continued to corrode his skin, turning his body red and causing visible damage to the naked eye.

Su Yan endured the severe pain and practiced the Golden Ape Posture in the tank. On one hand, he was in severe pain, and on the other hand, his heart was as heavy as water, as if he were in two different worlds, ice and fire.

'This guy is really cruel.'

Xu Zhongdao was also shocked when he saw Su Yan like this.

The skin corrosion has already caused blood to seep out. If this poison were used on an ordinary person, they would be like a shrimp that has shed its skin and would not likely survive.

Even if one has mastered the art of skin refining, such torture is still unbearable.

"Boy, mobilize your Qi and blood, absorb the medicinal power, and repair your skin membrane. The medicinal power, skin membrane, and Qi and blood will form a trinity and form a cycle. This will allow you to refine your skin membrane to a higher level and cooperate with the Golden Ape Jade Body Technique."

"Golden Ape Jade Body Skill?"

Su Yan heard what Xu Zhongdao said, but he had no time to think about it. Instead, he continued to condense new membranes according to what Xu Zhongdao said.

This poisonous skin powder contains medicinal ingredients that can help grow flesh and blood, and now they work together to release the medicinal effects.

Su Yan's membrane was being destroyed and repaired quickly.

In addition to the intense pain that felt like the corrosion and burning of flames, there was also a strange feeling like ants crawling and biting.

For a moment, even Su Yan felt so painful and itchy that his veins bulged.

This torture was repeated for a full two hours before all the medicinal effects were completely absorbed.

Su Yan jumped out. His skin and muscles were all red. His blood was surging, and he stood out in the complete Golden Ape Posture.

His muscles moved together, and his breath was surrounded by white mist. White mist also continued to rise around his body. It was not known whether it was the vapor from hot water or the manifestation of the surging qi and blood.

After a long time, Su Yan finished his training, his eyes as sharp as a blade.
