After returning to the Medicine King's Mansion, An Qingya arranged a place for Qin Yi to stay, and then retired first.

After a while, someone sent Qin Yi hundreds of pill recipes, as well as dozens of alchemy books.

"I don't know if the Chaos Stone Man will react to alchemy......"

Looking at the book on alchemy in his hand, Qin Yi waved his hand, and an alchemy technique was displayed.

Bang!

The Chaos Stone Man in his mind suddenly moved, and a wonderful light suddenly appeared in his hand, and a technique that was slightly different from the previous alchemy technique appeared in Qin Yi's mind.

"I'm not very familiar with alchemy, and this little bit of change is based on the medicinal materials I have swallowed and the familiar medicinal properties, and the change is not large. ”

Qin Yi shook his head and performed another alchemy technique.

Boom –

The stone figure in his mind shook again, and countless techniques suddenly appeared in Qin Yi's mind, and the previous alchemy techniques also began to change continuously, forming a new technique.

"When the two alchemy techniques are compared, there will be countless changes immediately. Okay, try the third course again. ”

Qin Yi didn't stop, and immediately opened the third alchemy technique.

Buzz –

More changes appeared, Qin Yi only felt that his understanding of the pill had undergone earth-shaking changes, and the various Dan Dao concepts and various mystical insights brought to him by the three alchemy techniques were more profound than martial arts.

"Although alchemy is an external way, it is also extremely useful. And the insights it brought me are also very deep, if I can integrate the Dan Dao, it will definitely be a great means. ”

Qin Yi didn't stop at all, and opened the rest of the alchemy techniques one after another, and all kinds of incredible methods appeared in his mind.

He only felt that in his mind, it was like a small wood bud, which was ingesting nutrients and growing continuously, and could break through the ground at any time.

But at the moment when he was about to break through the ground, Qin Yi suddenly felt a pain in his brain, and a piercing pain spread up, causing his whole body to be shaken.

"No! I'm mentally exhausted again!"

Qin Yi was bleeding from his mouth and nose, his face was pale, and his whole body was mentally exhausted and extremely weak.

"What is missing? I was the same when I deduced the true body of the Heavenly Demon, and I couldn't continue to deduce this alchemy technique, ......what was wrong?"

The Heavenly Demon True Body is a hand-to-hand combat magic skill that Qin Yi has achieved by fusing hundreds of fists and feet, but no matter how hard Qin Yi fuses, when he reaches the end, he will still fall short.

In the previous fight with Li Qi, he cast a Heavenly Demon True Body, and barely escaped with his life in Li Qi's hands.

But even so, the Heavenly Demon True Body that time was not perfect, and it was still a thin line.

This is a world of difference!

Qin Yi could even feel that if the moment the Heavenly Demon True Body really appeared, he was afraid that Li Qi would not even have a chance to breathe in front of him.

Is this what is missing from him, and why can't this last line be reached?

His mental power was exhausted, his mind was swollen, and he could only sit down reluctantly, relying on the "Suihuang Ming Emperor Sutra" to wash his body over and over again to speed up his spiritual recovery.

By midnight, Qin Yi's mind had finally recovered, and he took a breath and didn't dare to try the fusion technique again.

"It's a fantasy to fuse the exercises now, so it's better not to try. Before I can find out what I am missing, no matter what kind of fusion of exercises, I must first let go. ”

Shaking his head, Qin Yi took a Dan Fang from the desk and read it carefully.

"Juyuan Dan, Qi Nourishing Pill, Condensing Divine Pill ......"

Qin Yi glanced over and immediately found that these pills were all relatively common pills on the market, nothing was too rare, and the most precious one was nothing more than the Divine Concentration Pill.

These pills can be bought even outside the Medicine King's Mansion, but the price outside may be relatively high, and the pills they have accumulated are naturally not as good as the pills in the Medicine King's Mansion.

"Although I saved An Qingya's life, but in the end, Danfang is the foundation of the Medicine King's Mansion, and it is reasonable that people will not lend it to me. ”

Qin Yi didn't particularly care, these pills were all accumulated by generations of hard work. Just by testing the medicine, many people must have died.

This is almost a pill that has been piled up with human lives, and it is already extremely good to be able to give yourself these improved versions.

Qin Yi looked at the Dan Fang in his hand, and suddenly frowned.

"The nature of the cold heart grass is yin, although it is good to neutralize it with the Yuan Yang grass, it will cancel out most of the medicinal power of the cold heart grass, why not use the more neutral and peaceful Heyang grass?"

"And here, the heavenly willow wood is neutralized with the golden source fruit, but it is smelted with fine iron. Although the pill can be made, isn't it also refining the toxins in the metal? If you take it for a long time, it will be difficult to eliminate the erysipelas. ”

"Strange thing, strange thing! It's clear that it's better to change the ...... here."

Looking at the hundreds of pill recipes, Qin Yi's brows became tighter and tighter, and these pill recipes more or less did not match his philosophy. Seeing that he was very puzzled in his heart, he felt deeply puzzled by these Danfang.

"Could it be that it's because of the price of medicinal herbs?"

Some medicinal herbs are too expensive, and such problems may arise. But in fact, these are ordinary pills, and the medicinal materials used for alchemy are not expensive, and the medicinal materials used for neutralization can be some precious varieties.

Moreover, if one or two Dan prescriptions were like this, it would be fine, but every Dan prescription was like this, which had to make Qin Yi feel strange.

"An Qingya won't deliberately deceive me on such a trivial matter, learning alchemy is originally a matter of talent. She doesn't know if I can do alchemy, there is no need to do such a thing, so what is the problem?"

Qin Yi is bold and careful, this question seems to be unimportant, but it is related to whether Qin Yi's pharmacological research is correct and whether his alchemy techniques are normal.

After all, it was the first time for him to deduce the alchemy technique, and he didn't know if it was correct for all kinds of problems. If it is a deduced martial art, he can understand it with a slight figure in his own heart. But when he first came into contact with Danfang, he still didn't have much confidence.

"It's late at night, and I can't even find someone who understands to ask. That's it, I'll talk about it when I get up tomorrow. ”

Qin Yi shook his head and suppressed the doubts in his heart for the time being. When it comes to tomorrow, he will ask An Qingya, and he should be able to get a solution.
