In the alchemy room.

The walls and floors are made of dust-free stone to ensure there is no dust in the room.

Zheng Tuo even took a special shower and put on clean clothes.

After all, elixirs are for human consumption, and aside from the effects, they must be clean.

Take out the prepared materials one by one and place them on the table in front of you.

According to the records of the Spirit-Quenching Pill recipe, the spirit grass is divided into a certain proportion and then the elixir is started.

The art of alchemy is very difficult for immortal cultivators in the Qi refining stage.

There are two difficulties.

First.

Refining elixir requires using spiritual energy to transform elixir fire, decompose all materials, and then fuse them.

second.

In the process of fusion, strong mental power is needed to assist.

The difficulty lies in the fact that the spiritual power of those cultivating immortals during the Qi refining period is not very strong. Unless they are gifted, they will not be able to refine elixirs at all.

However, the above two points do not matter to Zheng Tuo.

The method of using spiritual energy to turn elixir into fire is very simple. He has already learned it and tried it several times.

As for his mental strength, he can say without showing off that he absolutely crushes his contemporaries.

Perhaps because of his two lifetimes as a human being, his mental strength is twice that of ordinary people.

Otherwise, why would he be better than Jiu Li'er when learning the art of formation?

With such a powerful mental power, he could actually use more convenient jade slips to study.

But for the sake of caution, he still insisted on using paper books, just to give people the illusion that his mental power was ordinary, so as not to get into any trouble.

Now that he needs to refine an elixir, he will naturally not hide it.

Activate the elixir fire method and use spiritual energy to transform the elixir fire.

The red elixir fire has no temperature and looks like a fake flame.

In fact, elixir fire is not an ordinary flame, but was developed specifically to burn spiritual objects.

Activate the Danhuo furnace to maintain a certain temperature in the furnace.

Then he began to add the required materials into the alchemy furnace in order.

Throughout the entire process, Zheng Tuo seemed cautious.

After all, it is the first time, so it will inevitably be a little tight. It should loosen a lot after a few more attempts.

When all the materials were put into the alchemy furnace, Zheng Tuo closed the lid of the alchemy furnace.

At this moment, he released his powerful mental power to wrap the alchemy furnace.

The alchemy furnace slowly rose into the air and slowly rotated.

In a trance.

Zheng Tuo entered a magical world.

In this world, all the alchemy materials have become extremely huge, as if they are being viewed under a microscope.

He transformed into a stream of elixir fire, tearing each material apart.

During the process, he could clearly feel that there were some unclean things on those huge materials trying to resist him.

But under the elixir fire, they all turned into flying ash and disappeared into the air.

Taking the essence and discarding the dross is what he is doing at the moment.

The whole process lasted ten minutes, and all the materials were refined and completed.

but.

With his cautious character, how could he be satisfied with just refining it?

and.

According to the records of the alchemy method he learned.

The quality of the elixir partly depends on the number of times the materials are refined.

generally speaking.

After refining it 1 to 2 times, there is a chance of refining a low-grade elixir.

After refining 3 to 5 times, there is a chance of refining a medium-grade elixir.

After refining 6 to 8 times, there is a chance of refining a high-grade elixir.

If it can be refined 9 times, there is a chance of refining the best elixir.

in this way.

He carefully controlled the elixir fire with his mental power and tried to refine all the materials.

Sudden!

Just when he was controlling the elixir fire and trying to change his position to continue refining, the elixir furnace made an uneasy tremor.

"Pfft..."

There was a sound like a flat tire.

Then the lid of the alchemy furnace trembled crazily as if it was epileptic, and streams of acrid black smoke came out from the opened gaps.

Seeing this.

With a thought in his mind, Zheng Tuo activated the five guardian arrays on his chest.

Five emerald green turtle shells surrounded him.

at the same time.

The clothes on his body flashed with several golden lights.

An instant teleportation array was formed, teleporting him to another alchemy room in the blink of an eye.

Everything seems to be very slow, but in fact it is completed instantly, as if it has been practiced millions of times.

In fact, Zheng Tuo did spend several months practicing his first reaction when encountering danger.

Through the bronze mirror, I saw that the alchemy furnace was just emitting black gas and had no other movement.

After repeatedly confirming that the furnace would not explode, Zheng Tuo shook his head.

The first time I made alchemy, I rushed to the street!

Return to the alchemy room.

"Bata!"

He raised his hand and turned on the homemade range hood above the alchemy room, sucking all the black smoke in the room into a magic weapon.

Zheng Tuo was mentally prepared for his first failure in alchemy refining in his life.

Pick yourself up, take out the second set of materials, and proceed with the second batch of elixir refining according to the order just now.

In a trance.

He came to that magical world again.

Use your body to turn into elixir fire, refine various materials, extract their essence and remove their dross.

This time he obviously sped up the whole process.

Finally, with his unrelenting efforts, he completed 3 material refinings.

This time he was not refining the material for the fourth time because he knew that refining it three times was his limit.

If the material is refined for the fourth time, it will definitely be discarded.

So he decisively opened the fire.

A faint fragrance came from the furnace and filled the entire alchemy room.

A middle-grade spirit-quenching elixir the size of a thumb was deposited in the elixir furnace.

Take the elixir out of the elixir furnace.

Zheng Tuo took out his magic glasses and observed carefully, then took out a small notebook and recorded it carefully.

After completing it, Zheng Tuo was in trouble.

He can't use the middle-grade spirit-quenching pill, and he won't give it to Xian'er, let alone sell it.

What to do, throw it away?

Looking at the Hunyuan elixir in his hand, it was a pity to throw it away.
To be continued...
