This protagonist is obviously very strong but extremely cautious

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 apart 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 was divided into a certain proportion and then the elixir was started.

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

There are two difficulties.

First.

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

second.

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

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

However, the above two points are not a problem for Zheng Tuo.

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

As for 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 formation method?

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 elixir fire.

The red elixir fire had no temperature and looked 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 times.

After 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 material is 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 as he was controlling the elixir fire and trying to change positions to continue refining, the elixir furnace gave off 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 in an instant, as if it has been practiced millions of times.

In fact, Zheng Tuo spent 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 movements.

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 the first time in his life when alchemy failed.

After picking up the mood, he took out the second set of materials and started refining the second batch of elixir 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 speeded up the whole process significantly.

Finally, with his unremitting efforts, he completed three material refinings.

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

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

So he fired decisively.

A faint fragrance came from the furnace, filling the entire alchemy room.

A thumb-sized middle-grade soul-quenching pill was deposited in the alchemy furnace.

Take the pill out of the alchemy furnace.

Zheng Tuo took out the magic glasses to observe carefully, and then took out a small notebook to record carefully.

After finishing, Zheng Tuo was in trouble.

He couldn't use the middle-grade soul-quenching pill, nor would he give it to Xian'er, let alone sell it.

What to do, throw it away?

Looking at the Hunyuan pill in his hand, it would be a pity to throw it away.

Forget it, I'll give it to you.

Summon a big yellow dog from the mirror world.

The big yellow dog is called Jiutong.

He watched Jiutong being born, and his foundation is very clean, so he plans to train him to be the steward of the mirror world.

After all, as his practice deepens, he must not have much time to take care of the mirror world, and he needs a guy who knows everything to help him take care of it.

Originally, he wanted to use a puppet.

But I always feel that puppets are unreliable, so it's more reliable to train a big yellow dog himself.

"Jiu Tong, eat it."

Zheng Tuo rubbed Jiu Tong's head and smiled.

"Woof woof!"

Jiu Tong opened his mouth and ate the middle-grade Soul-Tempering Pill like a stupid dog.

After all, the Soul-Tempering Pill is a spiritual pill, so it contains a lot of spiritual energy. The biggest function is to temper the soul, so it doesn't matter if it is given to Jiu Tong. After all, Jiu Tong is a fifth-level spiritual beast.

After eating the middle-grade Soul-Tempering Pill, you can clearly feel that it is quickly digested in Jiu Tong's body.

Zheng Tuo took out a small notebook and carefully recorded the whole process.

Although Jiu Tong is a beast, it practices the immortal method, which is completely different from those wild monsters outside.

So Jiu Tong can temper the soul just like normal immortals.

After recording the changes of the Soul-Tempering Pill on Jiu Tong.

Zheng Tuo returned to the alchemy table and continued to make pills.

Jiu Tong lay quietly on the side to refine the Soul-Tempering Pill in his body.

With the experience of the previous two times, Zheng Tuo began to get on the right track with ease.

In the third furnace, materials were refined 4 times, and a medium-grade Quenching Spirit Pill was successfully obtained.

After checking the records, it was eaten by Jiutong.

In the fifth furnace, materials were refined 4 times, and a medium-grade Quenching Spirit Pill was successfully obtained.

After checking the records, it was eaten by Jiutong.

In the tenth furnace, materials were refined 5 times and failed, and no elixir was obtained.

In fact, alchemy is a very boring thing.

It's as boring as a programmer reading code and an uncle paying public grain.

But for Zheng Tuo, it was like opening the door to a new world.

Because he was surprised to find that as he continued to make alchemy successfully and failed, his mental power actually improved.

Although it was very slow, it was definitely improving.

In the 80th furnace, materials were refined 5 times, and a medium-grade Quenching Spirit Pill was obtained.

After observation, a small amount of elixir patterns appeared on the Quenching Spirit Pill.

Elixir patterns are the symbol of high-grade elixir.

When elixir patterns appear on the refined elixir, it means that he is infinitely close to refining a high-grade elixir.

After recording, the elixir is eaten by Jiutong.

"Woof woof woof..."

Jiu Tong cried twice with tears in his eyes.

Zheng Tuo turned his head to look.

He found that Jiu Tong's eyes were red, his hair was standing on end, and he looked like he was holding back his poop.

In fact, it was the prelude to his breakthrough.

Zheng Tuo felt amused when he saw Jiu Tong like this.

Not a single top-grade elixir was produced, but you, the beast, broke through the current realm.

Well, break through quickly so that you can help me manage the mirror world.

Put Jiu Tong into the mirror world to break through.

He was studying how to improve the strength of his mental power.

The strength of his mental power now was the limit of refining materials five times.

Even if he refined elixir for 10,000 times, it was estimated that he could not improve it too much.

Why not go to the book pavilion to check if there is any way to improve mental power.

Zheng Tuo stood up and wanted to go to the book pavilion.

Suddenly!

A strange fluctuation came from the bronze ring on his finger.

Zheng Tuo explored it and took out a broken ancient jade from it.
