Incinerate tendons to wash the myelin pill.

This was the first earth-level elixir that Xu Yi came into contact with.

If the previous various pills were hard work and countless accumulations, he could refine the top grade or even the best. However, the ground-level elixir is obviously different, no matter how refined Xu Yi is, there is always a difference in meaning.

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

Ground-level pills are actually not much different from ordinary pills in nature, however, they require higher precision operations, that is to say, if ordinary pills are refined with the unit of measurement gram, then the incineration of tendons and marrow washing pills will need to be used in milligrams.

Before refining tools, that is, the Dan Furnace, had not been promoted, even if Xu Yi worked hard, if he wanted to refine a high-quality earth-level pill, it would be that kind of illusory thing. However, now that the Dan furnace has been changed, and it can still resonate with his spirit, and the earth-level magic weapon that is connected to him like flesh and blood, the situation is completely different.

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

Little by little, the drug began to ablate, quickly turning into a liquid state.

Although all of this happened in the Dan Furnace, Xu Yi observed it through the resonance between his divine thoughts and the Dan Furnace, as if his gaze was fixed on the Dan Furnace, and all the reactions were taken into his eyes.

Previously, when Xu Yi summed up his experience, the most he did was to estimate the time, but now he can make statistics in the way of witnessing it.

That is to say, one is blindfolded for alchemy, while the other is open to see the world, and the difference between this period is simply worlds apart.

One after another, the medicinal materials were thrown into the Dan furnace, and suddenly, Xu Yi's face sank slightly, and he found that after throwing in the medicinal materials 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.

The mind turned, and the magic circle under the Dan furnace suddenly began to run automatically, and then the burning speed of the Dan coal suddenly exploded, as if it opened the furnace mouth and continuously blew wind inside.

In this way, Xu Yi constantly adjusted the temperature and the frequency of the input of the medicinal materials, striving to give full play to the medicinal properties of each medicinal material.

Soon, the first pot of elixir was completed.

When Xu Yi lifted the lid, the rich medicinal fragrance suddenly wafted out. It's just that this furnace of elixir is just a low-grade incinerating tendon cleansing pill.

Although it is still inferior, Xu Yi is already satisfied.

He has refined so many times before, even if he summarizes and finds out a certain law, the probability of failure is more than eighty percent, and only a very few opportunities can become a Dan.

But this time, he didn't rely on luck, but with real ability. Moreover, in the process of becoming Dan, he also found many unreasonable places.

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

Previously, he kept trying, but he couldn't find the key points, so even if he wanted to change it, he couldn't do it. But now...... Xu Yi didn't say a word, cleaned up the Dan furnace, then re-ignited the fire, and began to put in the medicinal materials.

Every time he opened the furnace for alchemy, Xu Yi would summarize and record, and it was the same now.

After getting the new Dan Furnace, he played with it like a child got his favorite toy, and he left everything behind.

Ten furnaces of elixir.

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

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

Medium-grade tendon washing pill.

He finally took the most crucial step and refined the medium-grade earth-grade elixir.

Moreover, this is not the final ending, in the process of refining, more than ten violations were discovered. 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 grade of this elixir will not be intermediate.

"Goo-goo-goo. ”

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

Although there is a marching pill to satisfy hunger, today is a day of great joy, and Xu Yi doesn't want to force himself.

He finished packing up the ointment and went straight out of the yard.

"Senior sister, do you have any food?"

"It's already ready, warm on the stove. The figure flashed, Zhang Xinxin came to him, and said with a surprised face, "You have been in it for so long this time, can you afford it?"

Xu Yi raised his eyebrows and said, "Senior Sister underestimates me too much, I'm a man who has been in retreat for three days and three nights." ”

"Phew. Zhang Xinxin took a sip and said, "You use the Ground Rank Dan Furnace for alchemy?"

"yes. ”

"You ......" Zhang Xinxin looked at him suspiciously, "It always has been." ”

"Yes. ”

"Then don't you feel tired?"

"Why are you tired?"

"You're a ground-level magic weapon, and you must use spiritual power to use a ground-level magic weapon. You really think you are a ground-level cultivator, and using earth-level magic weapons for a long time is a taboo for human-level cultivators. ”

Xu Yi opened his mouth and stammered, there is still such a statement?

For others, this may indeed be an unavoidable problem. However, in Xu Yi's Ming Shang Dantian, the planetary visualization object no longer releases vitality all the time.

When the Earth Rank Dan Furnace was used for alchemy, Xu Yi's divine thoughts were indeed not idle. But this level of consumption is immediately filled by the vitality released from the visualization. If you want him to feel tired, it's impossible to just spend half a day.

"You ......" Zhang Xinxin bit his lip and suddenly asked, "Tell me, what exactly is your supernatural power?"

"Ah, don't you know, senior sister, my magic power is the magic power of endurance. ”

"Endurance supernatural powers? I've only heard of endurance supernatural powers in terms of true qi and physical strength, but what kind of stamina supernatural powers can make you maintain even your spiritual strength for so long?" Zhang Xinxin asked with a look of disgrace.

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

The endurance of physical strength and true qi is the credit of the little giant's transformation. But mental stamina is related to visualizing objects.

Zhang Xinxin looked at Xu Yi, who looked ignorant, and snorted lightly: "Forget it, maybe when you have a lot of knowledge in the future, you will be able to understand, let's eat." ”

"Okay. ”

Xu Yi immediately responded, but he was a little awkward in his heart, Zhang Xinxin didn't chase after him this time, he stalked and stalked, so he let himself go, and he was really a little unaccustomed to it.

Hey, I'm not going to be a masochist.

Zhang Xinxin's meals maintained the usual excellent level, so that Xu Yi, who was hungry and had his chest against his back, almost swallowed his tongue.

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