De Ligt looked at Carlos seriously and said word by word: "A young and gifted alchemist with a bright future. ”

Carlos was dumbfounded.

In the basement, while drinking wine, Du Buyi opened the sketches and notes he had stored in an old box.

But it was not long before he became tired of such futile efforts and became depressed with exhaustion. Putting down the bottle, he held his knees with his dead tree-like palms as he bent down and picked up the pieces of paper scattered from under a chair.

He stood up and took a few steps forward, and on the side of the Principle Alchemy Table, he lifted the curtain that covered a mirror, which was used for self-correction.

A projection appears in the mirror, a piece of alchemy previously recorded by the old alchemist.

When he faced the mirror, he began to gather his thoughts.

In the mirror, the figure was burly, with a full chest, and dense short white hair, which made the black eyes under the thick gray eyebrows glow, and he had an extraordinary enthusiasm and dedication to his alchemy.

Now the years are unforgiving.

Du Buyi stood in front of the mirror with his feet together and his body straight, and the projection screen disappeared, and there was only an old and stiff white-haired old man inside.

Du Buyi sighed.

Suddenly, in the mirror, he saw a curtain move behind him, and then the head of a handsome young man poked out, and only a looking head was sticking out.

The voice behind him asked:

"Teacher, are you there?"

He replied "Yes", turning around and recovering the mirror with a cloth to look towards the door with a shallow smile.

Carlos walked into the underground alchemy room, and when he was still at the door, he had already heard the loud sobbing sound of the steam engine, and now its life is also an old guy, Du Buyi scooped up a spoonful of liquid with a silver spoon, comforted the crying steam engine, and then said kindly to Carlos at the door: "Come in, little one." ”

Today is the agreed alchemy internship day, and Carlos is here for this.

"Teacher, you can just call me Carlos, you just looked in the mirror?"

"Yes, Carlos. He said, "I'm admiring myself, but I'm bumping into you." ”

He smiled and the wrinkles on his forehead soothed slightly, and then said:

"You can come in without reporting in the future, so there's no need to be polite. ”

Carlos nodded, and began to look at the furnishings in the basement, and in the center was a large workbench, which looked like an alchemy table.

Half of the table was filled with glass bottles of colorful liquids, a few gas-lit crucibles, and a tool table resembling a manual machine tool, rusted everywhere, with some hand tools in front of it and a high chair next to it.

In the left corner is an old-fashioned steam engine, connected to the workbench by a thick pipe, and when the steam engine is running, a trace of white steam will emerge from the pipe that is not very well sealed, forming a white cloud in that corner.

On the right is a long sofa with a blanket casually placed on the back of the sofa, and there is an air outlet on it, with a slight breeze but no light source shining in.

Du Buyi looked at Carlos, who didn't know what to do, and said: "Then what is the first thing you chose to alchemize, today is actually less than ten days, you still have time to prepare!"

Carlos knew that the old man was referring to the fifteen-day agreement, but he couldn't wait, if it wasn't for the witch and the demon affair that broke his plan, he would have chosen to come to the alchemy room on the sixth day.

"Yes, I chose to make a demonic potion of demonic breath?"

"Yes, it's to be expected that you want to use potions to speed up your absorption of dark qi, which is good, but these potions are not easy to mix, and they lack herbs. ”

Du Buyi watched Carlos pacing slowly, and said with some concern.

Carlos confidently said, "But there is no shortage of ores here, if you have enough herbal transformers." ”

Du Buyi glanced at Carlos appreciatively, pleased with his student's wisdom.

The old man is no longer young. But he still maintains a demeanor that never ages, which makes him more proud than his physical health.

The old man said in a low voice: "Look at you, you have done enough homework, the wild transformation of high-level alchemists is the basic ability of advanced level, and I do have a lot of conversion agents here, so what are you going to do?"

Carlos's eyes became more confident, the only thing he couldn't be sure about in his preparation for this alchemy was the source of the herbs, since there was enough source of the transformer, then the plan was half the success.

Non-elf-level herbs can be transformed through conversion agents, which is a very important introduction to the basic theory in the alchemy book.

The materials of the Demon Breath Demon Potion are not complicated, most of them are herbs, such as Demon Grass, Sunflower, and Fine Algae, which are not many in the barren land of East Cyprus, which is dominated by the desert, and few people buy and sell these, and there are black spot fish oil and some clear water, fish oil is a good medicinal material, you can buy some on the market, and there is nothing to say about clear water, as long as there are not too many impurities.

Everything is ready to go.

Carlos flipped through the notebook in his hand and read aloud: "The student is going to use the law of duality and bipolarity to add different proportions of herbal transformers to salt ore and tin ore to make materials with the characteristics of algae grass and sunflower, polish and pick up algae grass, and then use the material ore of sunflower to continue to add herbal transformer, refine a little demon grass, and completely prepare the materials of the demon breath demon potion." ”

Carlos looked at his notebook, and he saw the old man Du Buyi nodding slowly in agreement.

He then quickly and skillfully turned the next page and continued:

"Next, the seventh-stage method is used to dye the material, coagulate, distill, decay, calcine, sublimate, dissolve, and finally produce the finished product. ”

The so-called seven-step method is to form the sevenfold ladder connecting the earth and heaven by reference.

The alchemist transforms one material from one to the other, from the lowest base material to the highest one, until it is mixed into a finished product.

Because the transformation from low to high promotion is roughly divided into seven stages, it is called the seven-order method.

Du Buyi didn't agree or question when he heard this, but just asked lightly: "How long do you plan to complete the entire alchemy process?"

"An hour. ”

The biggest difference between the steam alchemist and the ancient alchemist is that he has a steam engine, which can greatly accelerate the alchemy process, so that the alchemy efficiency is greatly accelerated, in the past, it often takes half a day or even a few days to wait for the chemical evolution of the material catalysis, and after the high-power heating of the accelerated steam engine, the time may only take a few minutes, as long as there is alchemy as a material stabilizer, the material will not be destroyed because of the high temperature of the steam, which causes excessive fluctuations in the substance.

"Very well, let's get started. ”
