When Su Xuan first followed the mysterious person who taught him medical skills, the first step in learning medical skills was to immerse himself in the medicinal liquid made from various heavenly and earthly treasures, so that his body could withstand the powerful medicinal power of various medicinal materials.

And if you take out any medicinal herbs from that medicinal liquid, you can set off countless fanatical scrambles outside, which is no worse than the Eight Immortal Grass.

After soaking in the medicinal solution for nearly half a year, Su Xuan finally met the mysterious man's requirements.

At the same time, his blood also contained a huge medicinal power mixed with various powerful medicinal materials, and it was no exaggeration to say that Su Xuan's blood was itself a powerful medicinal material.

It's just that ordinary blood is not enough to resist the toxin of the Hades poison, and it takes Su Xuan's essence blood to be able to completely suppress its domineering poison.

Essence blood is the fundamental blood of the human body, and the loss of every drop of essence blood will cause irreversible damage to the human body, but at the moment, Su Xuan can't take care of so much.

"Xiaoying, I can cure Yaoyao's illness, don't worry." Su Xuan comforted.

Hearing Su Xuan say this, Lin Ying was also slightly relieved.

Su Xuan picked up Yaoyao and rushed to Du Renfeng's hospital with Lin Ying.

In order to cure Yaoyao's illness, Su Xuan needed to use his own essence and blood as a guide to practice an elixir in order to truly remove the toxin of Hades' poison.

And Su Xuan didn't have these tools at the moment, so he could only go to Du Renfeng's hospital to borrow them.

After Du Renfeng received Su Xuan's call, he also understood the urgency of the matter, and went to arrange it without saying a word.

When Su Xuan arrived, Du Renfeng had already vacated an operating room and specially prepared the tools that Su Xuan needed.

Entering the hospital, Su Xuan didn't talk nonsense, and directly asked Du Renfeng to lead him to the door of the operating room.

"Next, I will concentrate on treating Yaoyao and don't let anyone disturb me." Su Xuan said with a serious expression.

Lin Yingmei's eyes showed a look of worry, she vaguely felt that things were not so simple, but for now, she could only trust Su Xuan.

Du Renfeng nodded solemnly.

After Su Xuan entered the operating room, he closed the door tightly.

Looking at Yaoyao on the operating table, her eyes were closed tightly, and her face was painful, Su Xuan felt a cramping pain in her heart, if it weren't for herself, Yaoyao would not have suffered this kind of pain.

"Wang family, I swear, I will let each of you suffer ten times more pain than Yaoyao, a hundred times more tormented."

Su Xuan took a deep breath and forcibly stabilized his mind, there must not be the slightest mistake in the next process, otherwise, not only would he not be able to save Yaoyao, but even he would be implicated.

Closing his eyes and sinking his consciousness into his body, Su Xuan's breathing was even and long, and he was feeling the qi flowing around him.

Soon, he clearly felt that there was a breath flowing in his limbs, and that was the qi in the human body.

It's just that Su Xuan's qi is very different from ordinary people, more majestic and vast, if ordinary people's qi is only a trickle, then Su Xuan's qi is the ocean.

There is no comparison between the two at all.

Su Xuan condensed his mind on the majestic qi, and those qi suddenly converged towards his head as if he had been pulled by it.

All the qi gathered in his head at this moment, and then Su Xuan's breath condensed, his brows furrowed slightly, and he saw that all the qi gathered into a larger qi, rushing towards the center of Su Xuan's eyebrows.

A piercing pain came from the center of the eyebrows, as if something was about to emerge from it.

Su Xuan had no scruples, nor did he have any stagnation, and continued to pull the huge qi to hit the center of his eyebrows.

The sharp pain struck, and his mind was shaken, and Su Xuan's consciousness was almost a little unstable.

But he still didn't give up, gritting his teeth and continuing to pull the breath to hit.

Finally, with a sharp pain that almost made people faint, a thin slit cracked at the center of Su Xuan's eyebrows.

A drop of blood with a strange color seemed to be squeezed out of it by an invisible force, Su Xuan forcibly endured the feeling of fainting and presented the drop of blood with a special container.

This drop of blood is different from ordinary blood, the whole body exudes a bewitching red, if you look closely, you can find that this drop of blood seems to be alive, with strange patterns flowing on it.

This is Su Xuan's essence blood. Love you

At this moment, Su Xuan, who was using qi to force out the essence blood of his body, felt a huge sense of exhaustion hit him, and the scene in front of him seemed to become a little blurry.

"I can't fall yet, Yaoyao is still waiting for me to save her."

Su Xuan gritted his teeth and persevered.

You must know that the essence blood of the human body is not the same as ordinary blood, and even if you lose a little, it is harmless, and it is even good for the body, but essence blood is different.

The loss of a single drop of sperm and blood can have terrible consequences, and the feeling of exhaustion and fainting is only a preliminary reaction, and there will be various side effects later.

Therefore, people who study medicine are taboo about the waste of essence and blood, after all, this thing can be equated with the countdown of life, if the essence and blood are exhausted, the person will be almost the same.

Like Su Xuan, who uses essence blood to save people, I am afraid it is still a precedent in the entire medical community.

There is a special furnace next to the operating room, and next to it are all kinds of valuable medicinal herbs.

These things were all prepared by Su Xuan when he was on the road.

Su Xuan dragged his tired body and threw the herbs into the furnace in a specific order, and the flames burned under the furnace.

A strange fragrance suddenly emanated from the furnace and filled the entire operating room.

When asked about this strange fragrance, even Su Xuan felt a lot clearer.

"There can be no mistake in the order of putting medicinal materials, timing, and the grasp of the heat, even if it is a few tenths of a second slower, it will affect the final pill, and the refining of this emperor pill is really difficult."

What Su Xuan wanted to refine was an ancient elixir called Emperor Dan, which had a very long history, and was said to have been handed down during the Qin Dynasty.

As for the existence of this elixir, the patriarchs of some ancient families may have doubts, and the younger generation of medical circles have not even heard of this kind of thing for a long time.

But Su Xuan knew that the Emperor Pill was real, and he had seen the materials and methods of refining the Emperor Pill in an ancient book.

In fact, the refining materials of the Emperor Pill were not difficult to find, and even now they could be found quickly, which could be seen from the fact that Du Renfeng had prepared all the materials within half an hour.

What is really difficult is the refining skills and methods.

When refining the Emperor Pill, the alchemist needs to use spiritual power to control the degree of flame burning, so as to reach a subtle realm, neither too violent nor too gentle, which is the first step in refining.

And this step can almost isolate most people, after all, if the mental power is not very strong, rashly releasing the mental power is a very draining way to consume physical energy, let alone control the degree of burning of the flame.

I'm afraid that only Su Xuan's terrifying spiritual power can do it.

Separating the natal essence and blood, and releasing spiritual power to control the flames, Su Xuan's mind was still very tired, his eyelids drooped slightly, and the whole person seemed to be many years old.

But he gritted his teeth, his eyes wide open, and stared at the furnace with all his attention, not daring to make the slightest mistake.

Time passed, and the flames beneath the furnace seemed to dance in an eerie way.

If it weren't for the fact that the concentration of the elixir in the air was gradually increasing, Su Xuan would have almost wondered if he had failed.

A trace of white smoke rose from the furnace, and Su Xuan's eyes suddenly froze.

"Here we are."

Then came the most critical time.

I saw more and more white smoke rising from the furnace, and the entire furnace seemed to tremble a little, as if it could not contain this powerful medicinal power.

A crisp sound came from the furnace, and Su Xuan's face was happy.

"It worked!"

I couldn't wait to open the lid of the furnace, and suddenly a strange aroma came to my face like a wave.

And the moment he smelled this strange fragrance, Su Xuan's tiredness was suddenly swept away, and the whole person was instantly refreshed.

Even the pain that remained in the center of the eyebrows when the natal essence blood was separated before disappeared at this time.
