This protagonist is obviously very strong but extremely cautious

Refining the best elixir is not an easy task in itself.

The word "best" means extreme. It is not easy to do something to the extreme.

Zheng Tuo calmed down and used spiritual energy to transform the elixir fire. Then, he meticulously activated the elixir fire and refined each spiritual herb. The whole process was extremely serious.

The first step in refining the best elixir is to complete the nine extractions of spiritual herbs.

The nine extractions rely not only on strong mental power, but also on the familiarity with spiritual herbs, the precise control of the elixir fire, and the keen intuition of the surrounding spiritual energy... and so on, many matters that need to rely on experience and judgment.

A true alchemist is often the most able to endure loneliness and has the most peaceful mind.

Because the process of refining spiritual herbs is like the monthly salary of a middle-aged man, boring, tedious, uninteresting, and even wanting to die.

It is not like the normal meditation in practice.

A few decades have passed in a closed eye, a opened eye, and a few hundred years have passed in a closed eye, a opened eye, and a few hundred years have passed.

To refine spiritual herbs, you need to be 100% awake, 100% focused, and 100% correct in extracting all the essence of the spiritual herbs and condensing them into pills.

This process cannot tolerate even a hair's worth of mistakes.

One mistake will completely ruin a furnace of pills, especially the refining of top-grade pills.

However.

The word "concentration" seems to be tailor-made for Zheng Tuo.

He is a person who is very focused on everything he does.

In addition, he takes time every day to practice the ancient jade visualization method, so his mental power improves quickly, for the purpose of refining top-grade quenching pills.

Use your body to become pill fire and refine spiritual herbs.

Once, twice, four times, six times...

As time goes by.

It comes naturally, and all the spiritual herbs are refined nine times.

It seems simple.

In fact, he doesn't know how many times he has practiced, how many materials he has wasted, and how many pill furnaces he has broken to achieve such an easy result.

The spiritual herbs are refined.

He began to get to the point in an orderly manner and began to refine pills.

Dull, tedious, uninteresting...

That's for others.

For Zheng Tuo, he felt like he had entered a brand new world.

He was like a happy fish, swimming in this unknown ocean, enjoying his own happiness.

As the program progressed, the furnace in front of him vibrated slightly, indicating that the refining of the top-grade elixir had been completed.

Zheng Tuo, who had closed his eyes tightly, slowly opened his eyes.

There was nothing special about his brown eyes, not deep, not bright, and not filled with stars. If he had to find an advantage, it would be concentration.

He raised his eyes.

He looked at the alchemy furnace on the table.

There were no thunder and clouds, no strange phenomena, no colorful dazzling brilliance, and even no fragrance that the elixir should have.

"Did it fail!"

Zheng Tuo raised his hand to open the lid of the elixir furnace and looked down.

In the elixir furnace.

A brown elixir the size of a little finger lay quietly at the bottom of the elixir furnace like a dead object.

Take a closer look.

The brown pill didn't look like anything special, and was even several times more ordinary than ordinary pills. It was obviously a waste of refining.

Zheng Tuo put on a pair of gloves and carefully took out the brown pill.

And just when his fingers touched the brown pill, inexplicably, a savage mental force came along his fingers and attacked him.

Zheng Tuo reacted quickly and used his mental power to resist.

"Interesting!"

Zheng Tuo looked at the brown pill in his hand and whispered.

That was a very stubborn mental force.

Although it was very weak, it was as tough as a rock and fought against him fearlessly.

One of the characteristics of the best pill is that it has some spirituality.

"The world of cultivating immortals is indeed a magical world. A small pill has some instinctive spirituality like an ant moving."

Zheng Tuo controlled the glasses and stared at the best pill in his palm, trying to get some useful information.

Suddenly!

The best soul-quenching pill flashed several dazzling lights, like a light bulb, and then flew away from his palm with a whoosh.

Zheng Tuo did not make a move to capture it, because he had already set up several formations around it to prevent the top-grade Soul-Tempering Pill from escaping.

The top-grade Soul-Tempering Pill was no longer pretending to be dead.

Instead, it was madly bumping around in the alchemy room, trying to break a gap and escape.

But no matter how it bumped around, everything seemed so futile.

"Collect."

Zheng Tuo raised his hand, and the top-grade Soul-Tempering Pill returned obediently and fell into his palm.

Adjusted the glasses magic weapon, observed and recorded carefully, and then called Jiutong.

"Jiutong, the master promised you that he would help you complete the seven soul-tempering. This thing is a top-grade Soul-Tempering Pill. With the help of the Soul-Tempering Array, it should be able to help you complete the seven soul-tempering."

Jiutong stretched out his scarlet tongue, opened his mouth stupidly, and ate the top-grade Soul-Tempering Pill.

Then.

With the help of the Soul-Tempering Array, the soul-tempering began.

As usual, Zheng Tuo took out a small notebook and observed and recorded carefully.

The soul-tempering lasted for two hours.

When Jiutong opened his eyes, Zheng Tuo smiled.

Obviously.

Jiutong had completed seven soul temperings and became a being comparable to the immortal Li Jun of Chixiao.

"Woof woof..."

Jiutong shook his big head and kept rubbing Zheng Tuo's calves. His intimate appearance made Zheng Tuo happy.

Jiutong was like his own child. He was very happy as the owner to help Jiutong grow.

And he said that the breakthrough of the Nine-Barrel was within the scope of the plan.

He knew about the Nine-Barrel and the Top-Grade Soul-Tempering Pill.

After the Nine-Barrel successfully broke through, Zheng Tuo became busy.

In the following days, he refined all the materials into Top-Grade Soul-Tempering Pills.

After completion.

Looking at the pile of Top-Grade Soul-Tempering Pills in front of him.

It seems that there is no difficulty in refining Top-Grade Soul-Tempering Pills. Should we consider mass production and sales, or exchange them for some things we need?

Zheng Tuo thought.

The ancient books he consulted recorded that the soul was tempered seven times for the great perfection. After that, the ancient books did not say that the soul could not be tempered again, nor did they say that the soul could be tempered again.

So.

After many inspections, he found an amazing fact.

That is, the seven times of soul tempering is not the end.

No one knows how many times the soul is tempered to be the end.

It is also unknown since when the seven times of soul tempering is now the recognized highest record of soul tempering.

For a cultivator, he is in the spirit of exploration and discovery, and intends to try whether he can temper the soul on the basis of the seven times of soul tempering.

With such a plan, his first choice is Jiutong.

Jiutong is closest to him, and is obedient and sensible. As a tool dog, helping him complete the experiment is one of his duties.

But after thinking about it, he shook his head and denied it.

The eighth soul tempering requires very high talent.

Jiutong is just an ordinary dog, and he is afraid that he can't bear the risk of the eighth soul tempering.

He just wants to experiment, not to murder.

Jiutong is not okay, so his target in his mind, and the only choice, can only be the foodie fairy.

Seventh-grade spiritual roots, completing eight soul temperings, sounds completely feasible.

After determining the experimental target, he took out the communication spirit stone.

"Fairy, delicious food, come back quickly."
