Chi Nanxia gave her notes to Qin Yi and left.

She wants to prepare for the matter of going to the ruins of the Demon God Abyss, if it is really the secret realm of the Medicine Garden, it will have a huge role in promoting the development of Huabang's Dan Dao, and it can deliver a large amount of pills to the army fighting on the front line.

She left the Danxin Hall to Xu Caiyan and Qin Yi, and asked Xu Caiyan to teach Qin Yi some basic alchemy knowledge first.

Xu Caiyan directly took Qin Yi to the library of the Danxin Palace, where there were a large number of Dandao books collected by Chi Nanxia, many of which were classical authentic works left over from the ancient immortal world, which were extremely precious.

And most of the books stored in Dandaofeng's library hall are only copies of rubbings.

"Qin Yi, the first thing that alchemy students need to hold is the cognition of elixir."

Xu Caiyan took out a holographic projector from the bookshelf and said: "At present, we know a total of 227,317 kinds of elixirs, including about 150,000 kinds of primary, intermediate and high-level elixirs, more than 40,000 kinds of yellow elixirs, more than 10,000 kinds of Xuanpin elixirs, more than 8,000 kinds of earth-grade elixirs, and more than 1,000 kinds of heavenly elixirs. ”

This information can be stored directly on a computer, but no real alchemist will use these external devices.

External devices are only auxiliaries, and the brain is the real best repository for alchemists.

Only by keeping these elixirs in mind can we have a deeper understanding of the characteristics and effects of each herb, and only in this way can we control them freely when refining medicines and accurately respond to all changes that may occur at any time when refining medicines.

"There is no time limit for this, you can just watch it slowly, I remember that Senior Sister Yue Ying should have taken one day to write down fifty percent of the elixir, and then in three days, more than ninety-five percent of the elixir, this speed is also the fastest I have ever seen."

After finishing speaking, Xu Caiyan turned on the holographic projector.

A purple elixir appeared vividly in front of Qin Yi's eyes, and marked the various characteristics of the elixir.

"Thundering grass, thunder attribute primary elixir, explosive medicinal properties, suitable for the main medicine, can be combined with metallic elixir fusion refining, can not be fused with water attribute elixir, thundering grass within a hundred years of longevity, a hundred years to a thousand years for the maturity period, the mature period can be improved to the extreme, can be used. . . ."

Just to describe the relevant characteristics of thundering grass, it is enough to use nearly 1,000 words.

This thundering grass Qin Yi hasn't seen it yet.

However, he is no stranger to elixirs, the Lei Yuan Dao Fruit he swallowed during the mission in Dusk City is an elixir, and at least it is a rare elixir above the Xuan Pin.

There are also blood vein fruits, six-petal snake heart fruits, and so on.

These are all elixirs.

Xu Caiyan continued: "Okay, take your time, I just have an experiment to study, it's in the alchemy room next to it, if you have any questions, you can come and ask me directly." ”

"Okay."

Qin Yi responded, and after Xu Caiyan left, he went directly into the state of learning.

The memory of the warriors is excellent, and the powerful spirit body and spiritual power can greatly improve the memory.

Qin Yi's memory is even more terrifying.

With the breakthrough of the realm, his spiritual strength was once again greatly improved, almost doubling compared to before.

If the spiritual power of the Spirit Wheel Realm martial artist is around 500 points, Qin Yi's current spiritual power is probably more than 2,000 points, although it is far from being as strong as the Yuanying Realm with divine sense, but it is probably not much worse than the powerhouse of the Zhudan Realm.

The powerful mental strength made his memory even more amazing.

With just a glance, the Thundering Grass and all its information were already deeply imprinted in Qin Yi's mind.

"Sanyuan fruit, a wood-attribute primary-level elixir, has mild medicinal properties, suitable for dispensing, can be combined with fire attribute elixir fusion, and cannot be fused with metallic elixir."

"Bixin Water Lotus, the primary elixir of water attributes...

As Qin Yi clicked, different elixirs appeared in front of his eyes.

Gradually, the speed of Qin Yi's memory became faster and faster, as if he had entered a wonderful rhythm, and in the end, it was so fast that the projection screen seemed to be fleeting, so fast that it was almost impossible to capture with the naked eye.

Of the 150,000 or so primary, intermediate, and high-level elixirs, it only took Qin Yi less than two hours.

If Xu Caiyan is here, I'm afraid she will be dumbfounded.

However, starting from the Huangpin elixir, Qin Yi's speed began to slow down slowly, and the higher the grade of the elixir, the more detailed the description of various characteristics became, often more than 10,000 words.

I don't know how long it took, an incomparably familiar elixir appeared in front of Qin Yi's eyes.

"Lei Yuan Dao Fruit, Thunder Attribute Xuanpin Elixir, born by condensing the laws of the thunder system, is a natural Dao fruit, which can mature in one day, or grow in 100,000 years, which can enable cultivators to improve the perception of the laws of the thunder system, awaken the talent of the laws, which contains the power of the Great Dao of the Laws, and refining the medicine can improve the grade of the elixir. . . ."

As Qin Yi expected, the Lei Yuan Dao Fruit was a Xuan-grade elixir, and when Qin Yi swallowed it directly, it actually greatly weakened the medicinal properties of the Lei Yuan Dao Fruit.

Lei Yuan Dao Fruit was refined into an elixir, and the medicinal properties could at least increase exponentially.

None of that matters, though.

At that time, if Qin Yi hadn't swallowed the Lei Yuan Dao Fruit, I am afraid that he would have already become the food in the mouth of the Lei Yin Demon Crocodile.

-------------

In the alchemy room, Xu Caiyan put down the notes in her hand a little tiredly, and her white little hands kept rubbing her temples.

Her cultivation is not weak, she has a ground-level spirit body, and she has condensed the two-sided spirit wheel, but the time spent on concentrating on research for five or six hours is extremely energy-consuming, even with her cultivation, it is a little unbearable.

"I don't know how Qin Yi is studying, let's go and take a look."

As a senior sister, Xu Caiyan is still very competent, she didn't rest, she got up directly and walked out of the alchemy room.

In the library, Qin Yi is still studying.

But when Xu Caiyan saw what Qin Yi was learning, the whole person was obviously stunned.

Qin Yi is learning, but what he is learning is no longer the cognition of the elixir.

What appeared in the holographic projection image was an extremely complex advanced information, including the combination and substitution between elixirs and elixirs with different attributes, as well as the chemical reactions after the fusion of multiple elixirs, and so on.

The advanced data constructed by more than 200,000 kinds of elixirs is more complex and difficult than tenfold.

However, this is also the basic knowledge that alchemy students must master.

Only by mastering these basic knowledge, can you truly understand that if you make good use of the characteristics of each elixir, you will be qualified to start refining pills.
