Xu Yi gave up his control of the earth spirit and allowed the earth spirit that he had obtained through hard work to disintegrate. He jumped up, rushed to the desk, grabbed the large paper several feet wide, and stared at the colored tables painted in different categories.

Xu Yi looked ferocious, his body trembled slightly, and he muttered something, "One hundred and eight medicines, black as the main color, twenty-one, white as the main color, twenty-one, purple as the main color, twenty-one, twenty-one, twenty-one, twenty-one, all twenty-one..."

"It's definitely not a coincidence, it's a rule, an unprecedented rule, haha, I'm going to post..."

Xu Yi still couldn't help but shout, which made Qiuwa turn up, glanced at him, slipped down the hanging basket, and disappeared. It was obvious that he had changed his place and went to hide from Qingjing.

The earth spirit showed pure blackness, which immediately made Xu Yi realize that the other four spirits must correspond to the other four pure colors.

With the clarity of the different spiritual properties, Xu Yi corresponds to the main color of the spectrum of 108 medicinal properties, and it is easy to distinguish which medicinal properties are playing a leading role, because the presentation of color is clear at a glance.

He counted carefully and found that the five elements of gold, wood, water, fire, earth and other spiritual qualities, each of which occupy the dominant position, had twenty-one medicinal properties.

The remaining three medicinal properties spectrums, one is bright, the other is transparent, and the other is dark, and there is no obvious color, which is very strange.

Xu Yi inferred based on the known spiritual power attributes that the remaining three unknown attributes are probably two celestial spirits, one is the wind spirit and the other is the thunder spirit. The last one is not clear, so he can only guess that it is a symmetrical mush-up of various attributes.

Of course, this is just a guess.

However, with the great discoveries before, Xu Yi was confident that this final article was completed and it was a super powerful article.

After all, research on alchemy is in full swing. As far as he knows from the Golden Book, many studies are based on specific medicinal materials and alchemy pills, which cannot be raised to a systematic level at all.

Even the innovative alchemy method he had seen before was improved by the discovery of spiritual essence by the master of alchemy through extraordinary efforts.

This kind of improvement is not universal.

So far, only a few commonly used elixirs such as Yuan Dan have been successfully innovated in the refining method.

Other elixirs are even more exploring.

There are 108 kinds of medicinal properties, each of which contains a mixture of different spiritual properties. It is too difficult to study thoroughly, especially the presentation of complex medicinal properties, without any regularity, which has brought great trouble to the vast number of alchemy practitioners.

Now, Xu Yi has discovered an important rule intuitively and clearly through the color analysis of the spectrum.

This rule is not limited to three or two kinds of medicinal properties, but includes all medicinal properties.

If spiritual matter is compared to elements and medicinal properties to chemical substances, the important rules discovered by Xu Yi through the spectrum are comparable to the periodic table of elements made by Mendeleev, and the significance is indescribable.

It is precisely because Xu Yi deeply understood the great significance of this discovery that he was so ecstatic.

The ecstasy did not last long, and Xu Yi quickly calmed down. He knew very well that this discovery was still a long way from the publication of Dingwen.

Because he could not directly say what the color of the spectrum is, and what if he counts it once, I am afraid that if such articles are posted, they will be thrown into the garbage dump after they are posted.

All he had to do was to put forward hypotheses and use a lot of experimental facts to confirm his guesses.

This is like proposing a mathematical conjecture and using a huge enumeration method to prove this conjecture.

Of course, Xu Yi does not need to be fully proved, he only needs partial listings. The rest are the matters of review and editors, and the huge number of readers of the gold book.

After all, Xu Yi has seen too many speculations in the Golden Book, but most of them are ultimately proven to be nonsense.

Three more months have passed, and Xu Yi has not taken a step to refining the house.

During this period, her mentor Xuan Lengyan had come to see him several times. At first, Xuan Lengyan also made a gesture of relief that a child could be taught. Later, when she looked at Xu Yi again, her eyes changed a little.

She had seen a monk who was obsessed with alchemy, but she had never seen such a desperate study.

She heard from Qiuwa that Xu Yi's three months of sleep lasted no more than twelve hours.

Later, Xuan Lengyan couldn't help but persuade her. Xu Yi only said that she knew her mind, and Xuan Lengyan didn't say much, so she stopped coming.

Xuan's cold-sex feeling of this apprentice who was accepted for his evil tastes became complicated day by day.

Especially after getting along with Qiuwa for a long time, I heard a lot about Xu Yi, which was like listening to the historical facts of a legendary hero.

Of course, Xuan Lengyan didn't think what Qiuwa said was true. It must be that the little guy was too young and took Xu Yi's self-proclaimed as real.

However, even if 10 or 20% of the story is true, it is enough to prove that this is an amazing guy.

It also just explains why this guy is so difficult.

On the 113th day of Xu Yi's retreat, his eyes were bloodshot and thin, holding a stack of papers full of words, laughed to the sky, and his laughter was still not over, and he fell down straight.

Xu Yi slept for four days and five nights. When he woke up, he was already lying in the room and his consciousness recovered. He jumped up in a hurry and searched everywhere. Soon, in the box on the bedside table, he found the stack of paper filled with words.

Xu Yi grabbed it, as if he had pinched a rare treasure.

"Aha, you're awake, Uncle Beard, you're sleeping so hard."

Suddenly, Qiuwa slipped in, jumped gently, jumped onto the bed, got into his arms, and leaned into his ear, "Uncle Hu Zi, are you embarrassed? You slept so hard, but Sister Xuan brought you to bed. When they left, you actually held someone's hand, yelling "Don't leave". I was so embarrassed for you. If I hadn't hidden under the ground quietly, Sister Xuan would have been so embarrassed."

Xu Yi gently lifted her nose, "What did you say, I don't remember anything."

He suddenly appeared in his mind, dreams of sleeping in his dream. In the dream, he met Xia Zimo and wanted to grab her, but he couldn't. Later, he finally grabbed Xia Zimo's hand. When he looked carefully, Xia Zimo's face turned into Xue Zihan, suddenly became Yin Qiu, and Yan Zi's, making him extremely confused.

Qiuwa laughed, "Don't worry, I put away your treasures in advance, and didn't ask Sister Xuan to see them."

Who is more important, who is closer and who is far away, the little guy is clear.

"Well done, with a prize. Today I will do nothing and go out with you."
