My magical power has skills

Burning tendons and cleansing marrow pill.

This is the first earth-grade pill Xu Yi has come into contact with.

If he can refine the various pills before through hard work and countless accumulations, he can refine the best or even the best. However, the earth-grade pill is obviously different. No matter how Xu Yi refines it, it is always a little bit different.

Through countless experiments, Xu Yi also has a profound experience.

In fact, the earth-grade pill is not much different from ordinary pills in essence, but they require higher precision operations. In other words, if ordinary pills are refined in grams, then the burning tendons and cleansing marrow pills need to use milligrams.

Before the refining tools, that is, the pill furnace, were upgraded, Xu Yi tried his best to refine high-quality earth-grade pills, which was also a matter of luck. However, now that the pill furnace has been changed, and it can still resonate with his spirit and is connected to him like flesh and blood, the situation is completely different.

As soon as the medicine entered the pill furnace, Xu Yi immediately sensed the subtle changes in it.

The medicine began to melt little by little and quickly turned into liquid.

Although all this happened in the furnace, Xu Yi observed it through the resonance of his mind and the furnace, as if his sight was fixed on the furnace and all the reactions were in his eyes.

Previously, when Xu Yi summed up his experience, he did the most to estimate the time, but now he can use his own eyes to count.

In other words, one is blindfolded to make medicine, while the other is open-eyed to see the world, the difference between the two is simply a world of difference.

One after another, the medicinal materials were thrown into the furnace, and suddenly, Xu Yi's face sank slightly. He found that after the medicinal materials were thrown in this time, the melting speed of the medicinal materials was somewhat different from before, resulting in a slight difference in the color of the medicinal liquid.

No, the temperature is too low.

With his mind turning, the magic circle under the furnace began to operate automatically, and then the burning speed of the coal suddenly burst out, as if the furnace mouth was opened and the air was blown into it continuously.

In this way, Xu Yi constantly adjusted the temperature and the frequency of adding medicinal materials, striving to maximize the medicinal properties of each medicinal material.

Soon, the first batch of pills was completed.

When Xu Yi opened the lid, a strong medicinal fragrance immediately wafted out. However, this batch of pills was only a low-grade burning tendons and cleansing marrow pill.

Although it was still low-grade, Xu Yi was already satisfied.

He had refined it so many times before, even if he had summarized and explored certain rules, the probability of failure was more than 80%, and only a very small number of opportunities could make the pill.

But this time, he did not rely on luck, but on his real ability to make the pill. Moreover, in the process of making the pill, he also found many unreasonable places.

What the alchemist has to do is to control the details and make all the unreasonable places reasonable and orderly.

His previous approach was to keep trying, but he couldn't find the key point, so even if he wanted to modify it, he had no way to start. But at this moment... Xu Yi cleaned up the furnace without saying anything, then re-ignited the fire and began to put in the medicinal materials.

Every time he opened the furnace to refine the elixir, Xu Yi would summarize and record it, and it was the same now.

After getting the new furnace, he was like a child who got his favorite toy, playing with it non-stop and forgetting everything else.

Ten furnaces of elixir.

When the tenth furnace of elixir was opened, the medicinal fragrance that permeated the void suddenly had a little difference.

Xu Yi's eyes were faintly shining, he picked up a little bit of ointment with his fingertips, tasted it, and finally showed satisfaction on his face.

Intermediate-grade burning tendons and cleansing marrow pill.

He finally took the most critical step and refined a mid-grade earth-level elixir.

Moreover, this was not the final outcome. During his refining process, he found more than ten inconsistencies. In the future refining, he will try to correct and change them one by one. If all these parts become perfect, it is estimated that the level of this elixir will not be intermediate.

"Gurgle, gurgle."

Suddenly, a strange sound came from his stomach, and Xu Yi realized that his stomach was already empty.

Although he had the marching pills to fill his stomach, today was a big day, and Xu Yi didn't want to force himself.

He packed up the ointment and went out of the yard directly.

"Big sister, is there any food?"

"It's been prepared a long time ago and is warming on the stove." A figure flashed, and Zhang Xinxin came in front of him, looking surprised and said, "You stayed in there for so long this time, can you handle it?"

Xu Yi raised his eyebrows and said, "Big sister, you underestimate me too much. I am a man who has been in seclusion for three days and three nights."

"Bah." Zhang Xinxin spat, "Are you using an earth-level alchemy furnace to refine the elixir?"

"Yes."

"You..." Zhang Xinxin looked at him suspiciously, "Always."

"Yes."

"Then, don't you feel tired?"

"Why should I be tired?"

"You have an earth-level magic weapon, and you must use spiritual power to use an earth-level magic weapon. Do you really think you are an earth-level practitioner? Using an earth-level magic weapon for a long time is a taboo for human-level practitioners."

Xu Yi was speechless. There is actually such a saying?

For others, this may indeed be an unavoidable problem. However, in Xu Yi's Mingshang Dantian, the planet visualization object is constantly releasing vitality.

When using the earth-level alchemy furnace to refine the elixir, Xu Yi's mind was indeed not idle. However, this level of consumption was immediately filled by the vitality released in the visualization object. It is impossible for him to feel tired in just half a day.

"You..." Zhang Xinxin bit her lip and suddenly asked, "Tell me, what is your magical power?"

"Ah, Senior Sister, don't you know that my magical power is endurance magical power?"

"Endurance magical power? I have only heard of endurance magical powers in terms of true qi and physical strength, but what kind of endurance magical power can allow you to maintain your spiritual power for so long?" Zhang Xinxin asked with a bad face.

Xu Yi spread his hands, his face full of helplessness.

The endurance of physical strength and true qi is the credit of the transformation of the little giant. But mental endurance is related to the visualization object.

Zhang Xinxin looked at Xu Yi, who looked confused, and snorted, "Forget it. Maybe you will understand it when you have more experience. Let's eat."

"Okay."

Xu Yi responded immediately, but he felt a little uncomfortable. Zhang Xinxin didn't pursue him this time and let him go. He was not used to it.

Hey, I won't become a masochist.

Zhang Xinxin's food maintained the usual excellent standard, and Xu Yi, who was so hungry that his stomach was pressed against his back, almost swallowed his tongue.

After dinner, he returned to his yard and opened the book sent by Jin Liang and read it carefully.
