After resting for a night, the next morning, Lin Shan went straight to Shimen Academy, he had already inquired about the location of Wang Feng, and found a place where a magnificent building covering an area of several acres rose from the ground, with three stories high.

When I came to the front of the building, I found that there were two guards at the door, and their cultivation was not low, both of them were in the sixth-level cultivation of the Yuan Dynasty, which was higher than Lin Shan.

He showed the jade slip to one of the guards' disciples, and when he finished inspecting the jade slip, the disciple asked him, "Senior Brother Lin, are you going to the first floor?"

"Senior brother, is it possible that each floor has a different charge?" A look of surprise appeared on Lin Shan's face, this Wang Feng did not introduce.

"The first floor collects three low-level spirit stones a day, and the second floor collects ten low-level spirit stones a day. ”

Lin Shan rubbed for a moment, then gritted his teeth and took out three low-level spirit stones from his arms and handed them to the guard disciples, holding back a sentence from his mouth: "I'll look at the first floor."

The guard disciple took the spirit stone, and at the same time handed Lin Shan a piece of jade slip, signaling that he could go in, Lin Shan took the jade slip, only to find that this building had no gate, only a square dark entrance, through this entrance, there was nothing to see inside.

He raised his legs, and just stepped to the entrance, the jade slip he had just received in his hand suddenly emitted a soft white light, shining at the entrance, and the entrance actually produced a burst of aura fluctuations, and the black entrance suddenly cracked a light gap, just suitable for a person to enter.

Lin Shan hurriedly stepped into the light crack, his ears seemed to hear a soft sound of "whew", the scene in front of him changed, and there were rows of bookshelves in front of him, each of which was filled with books made of cowhide or thumb-sized jade slips, and there were two stairs at both ends leading to the second floor.

What surprised Lin Shan was that there were already a few figures swaying inside the first floor, he originally thought that he was the earliest, but it seemed that there were many hard-working people.

He sank his mind, thinking about the three spirit stones in his heart, which had to be read enough, and looked for them one by one towards the cards on the bookshelf.

"Initial planting",

"Fire Bomb",

"Introduction to Spiritual Materials",

"Introduction to Fire Exercises",

"Beginner Technique" ......

One by one, the scrolls or jade slips of spell skills and academics kept jumping into Lin Shan's eyes, and halfway through, he had a preliminary understanding of the scrolls or jade slips on the first floor, whether it was skills or academics, they were all recorded at the elementary level, and presumably the knowledge stored in the first floor was the introductory knowledge in the cultivation of immortals.

After a while, Lin Shan finally found a jade slip that he urgently needed now, he took the jade slip into his hand, and lost his spiritual power, and a large amount of information poured into his mind.

"Alchemy, first of all, there must be a Dan furnace, a good Dan furnace can improve the success rate of your alchemy, and can improve the quality of the pill!"

"Alchemy, you can't use mortal fire to refine it, you must use the monk's primordial fire of the gods. ”

"Yuan Shen Huo, what is this?" This was a new understanding for him, and he hurriedly continued to browse.

"The so-called fire of the gods, is a skill to transform the body's aura into spiritual fire, for the monks of the fire spirit root, it is similar to the generation method of the fire spirit bullet, run the aura in the body to the palm of the hand, control the degree of retraction of the aura, feel the fire aura between heaven and earth and guide it to the hand, and the external aura in the body is combined together, it will generate the fire of the primordial spirit, if you can better sense and control the fire aura between heaven and earth, the release of the fire of the primordial spirit will last, other monks who are not the root of the fire spirit, please refer to the fire skill of the primordial god. ”

"It should be noted that in the process of alchemy, the fire of the primordial gods cannot leave the furnace until the pill is formed, so the monk needs great patience and perseverance, and he also needs to have enough cultivation, if you are ready, congratulations, you can start learning alchemy now. ”

Seeing this, Lin Shan suddenly realized, he finally understood the function of the two holes at the bottom of the black pill furnace, which was obviously to release the fire of the primordial god to the alchemist.

"First of all, we must first explain the general steps of alchemy, the general pills are made by mixing many medicinal materials together, so in the process of refining, we must first refine the essence of heaven and earth contained in the medicinal materials one by one, and then mix the essence of various medicinal materials together according to the proportion of the pills, and then refine them again, and finally form the required pills. ”

Lin Shan nodded, he had seen a tray and a switch in the black Dan furnace before, he didn't know what it was for, and he understood it when he saw it.

The black tray is used to hold the refined medicinal materials, if the essence of the medicinal materials is raised, the slightly heavier essence can fall to the bottom of the furnace through the small mesh tray, and the remaining lighter debris is retained on the mesh tray to control the bulge on the furnace body, which can pour out the debris and take the essence of the bottom of the furnace.

Lin Shan finally understood the use of the black pill furnace, and delivered the medicinal materials from the furnace lid for refining, through the mirror, he was able to understand everything in the furnace during the alchemy, and the two holes under the furnace were the entrances to the fire of the primordial gods, and after the alchemy was completed, the bulge on the furnace was controlled to obtain the essence and residue of the medicinal materials.

The back of this jade slip mainly explains the matters that need to be paid attention to in the process of alchemy, such as how to concentrate yourself, how to control the heat of the fire of the primordial spirit, what symptoms need to be stopped when the Dan furnace appears, to prevent the furnace from bursting, and so on.

After browsing the information provided by this jade slip, Lin Shan's heart began to burn, now that he has guidance, and there is a Dan furnace, everything is ready, so he will send medicinal materials to practice, so what kind of pill should he practice first?

"The simplest pills are hemostatic pills and broken valley pills. Wait, these pills, you still need to have a formula!" Lin Shan suddenly realized, quickly put away the jade slip and lowered his head to search carefully, this time it was very fast, this row of jade slips or books are all about alchemy, Lin Shan grabbed a jade slip, and its sign read: "Beginner pill formula." ”

Activating the jade slip, the relevant elixir formula information poured into his brain.

Hemostatic Pill: Lingcao Essence, 7 Cheng, Low-grade Diye, 2 Cheng, Low-grade Yellow Leaf Ling, 1 Cheng.

Broken Valley Dan: Linggu, 7 percent, low-grade ginseng, 2 percent, low-grade Chiba Ling, 1 percent.

Low-grade Huiling Pill: low-grade purple root, 6 into Lingcao, 2 into Lingcao, 1 into low-grade sand leaves, 1 into low-grade black leaves, 1 into ......

The names of many low-grade pills were recorded in this jade slip, but the recipes for Xiuyuan Dan and Zhuji Dan were not found.

"It must be on the second floor, ten low-rank spirit stones! It's okay, hahaha...... Fortunately, it is recorded on the Five Elements Bead. Thinking that he could save ten low-grade spirit stones because of this, the corners of Lin Shan's mouth almost cracked.

As soon as he thought of the second floor, his mind moved, and then he carefully moved to the staircases on both sides of the first floor, noticed that there was no one around, and secretly raised his legs to step up, but his legs were lifted out, but he was stopped by an invisible soft force at the stairs.

"I think that there are small formations at each staircase, and the magic circle is a thing that I will have time to understand well in the future. This situation was expected by Lin Shan, and he was just curious and wanted to investigate, so he returned to the row of jade slips in the alchemy and continued to check other relevant information.

"Alchemy Experience" tells the story of a disciple in the late stage of the cultivation of the Yuan Dynasty in the process of alchemy, Lin Shan looked at it intently, and also gained a lot, such as because the disciples of the cultivation period are not strong enough, how long should the alchemy be controlled, and what pills are best to refine.

There were also a few similar scrolls, the more Lin Shan read, the more itchy his hands became, he suppressed the impulse in his heart, and kept silently reciting the three spirit stones in his heart for a day, so he began to wander around the first floor to check other materials.

A "Beginner Spell Technique" jade slip entered Lin Shan's eyes, his eyes narrowed, and he quickly activated it, his face suddenly turned red, and there were many cultivation formulas of the Five Elements Spell recorded on it.

"Fire Bullet", "Quicksand", "Petrification"......

These spells are all vivid, there are many Lin Shan has already learned, and more are not, in Ethereal City, a spell scroll is five low-level spirit stones, thinking of the fifteen spirit stones that were spent before the Wind Spirit Valley, Lin Shan's heart twitched for a while.

Although he couldn't take them out, Lin Shan, who had a good memory, still memorized a lot of spell formulas, and thought about returning to the West Mountain Peak to record them immediately.

This Shimen Academy is still good, although it cost him three spirit stones, it really helps a lot for cultivation, thinking of this, a smile appeared on his face.
