Tian Xu entered the Yin Yang Ding space and found that the third pile of jade plates was indeed ready to read. However, this pile of jade plates is a bit strange, not every piece can be read, but only one can be read. And the jade plates were not arranged in order, and he tried for a while before he could find out what could be read from the remaining seven piles of jade plates.

It was a pile of light green jade plates, and there were five pieces in total. When he probed the aura into one of them, he did not directly receive the information recorded in the jade disc as before, but heard a female voice full of vicissitudes: "Yes, it will be Ning Dan so soon." I didn't expect that after 10,000 years, in the last days when the aura was exhausted, there would still be cultivators who could condense the pill within a year, and it really didn't disappoint me. ”

Tian Xu's surprise could not be expressed in words, he never thought that Emperor Shennong would be a woman. He digested the news slowly and didn't speak for a moment.

Unexpectedly, the voice seemed to have guessed his thoughts, and said, "Don't be surprised, I am Shennong, a woman." ”

"In my time, men were respected. Because men are agile and strong, they are mainly responsible for war and hunting, while women are weak and mainly responsible for gathering and farming. At that time, there were frequent invasions from other worlds, the enemy was strong, and the men's war pressure was huge, and there was no time for hunting, resulting in a shortage of food. Deeply aware of the hardships of human beings, I tasted all kinds of herbs, found edible plants from them, cultivated them, and finally obtained grains that could be used as staple food. At the same time, some plants that are not suitable for food due to abnormal properties are combined and matched as drugs for the treatment of diseases caused by abnormalities in the five elements. Finally, I used some medicinal materials with special properties and rich spiritual energy content, which were compatible with other medicinal materials, and used a special process to refine them, and obtained an elixir that can offset the failure of spiritual energy in nature. And I myself have reached the pinnacle of the cultivation world because of my perception of the natural world. It is precisely because of these that I am respected as the Great Emperor by the cultivation world of the world. ”

"I am the first cultivator who is not revered as a Great Emperor because of the merit of creation, and after me, it seems that no Great Emperor has appeared, that is to say, I am the last Great Emperor. ”

"Regarding grains and medicine, future generations have been creating continuously, and they have far surpassed me. There is only the elixir, to borrow the words of the ascendant who is revered as Lao Tzu, and it is mysterious. Later generations did not innovate, but continued to misunderstand all kinds of things, and finally was called a deceitful evil art by the secular world. ”

When Tian Xu heard this, he asked curiously, "Emperor, is this your photo, or are you talking to me?"

The voice of Emperor Shennong said, "This is just a wisp of my residual divine thoughts. I have waited for more than 10,000 years in this yin and yang tripod to see you today, and it can be said that I exist to wait for your appearance. Now that you have appeared, you are full of qualifications and luck, which is enough to comfort me. I keep this remnant just to say hello to future heirs, and I will never appear again. Work hard, it will be your fate to lead the Earth Cultivation Realm to fight against foreign enemies. ”

Tian Xu didn't understand what Emperor Shennong meant by fighting against foreign enemies, so he hurriedly asked, "Emperor, who are you talking about foreign enemies? What will I do in the future?"

However, the voice of Emperor Shennong did not appear again, leaving only Tian Xu, who looked confused, in a daze there.

He sorted out his thoughts, leaving behind the surprise that he was chosen as the heir by Emperor Shennong, and also the surprise that Emperor Shennong was a woman, and reached out to pick up a few other light green jade plates, and the contents recorded in the jade plates entered Tian Xu's mind one by one.

The four jade plates recorded are four parts: "Common Knowledge of Alchemy", "Common Dan Formula", "Yin and Yang Symbiosis" and "Space Compression".

The jade disc of "Alchemy Common Sense" records some basic principles of alchemy, such as the classification and identification of pills, the composition and mode of action of pills, the compatibility and conflict of alchemy raw materials, the commonly used techniques and utensils of alchemy, etc., which are indeed some very basic knowledge.

Tian Xu learned from this that the pill can be divided into ten major levels, which are from one to ten, and each level can be divided into upper, middle and lower grades. These levels can also roughly correspond to the ten great realms of cultivation, and the Ning Dan realm that he has just entered is only the third realm among the ten cultivation realms. It seems that this cultivation path is still very long. Now he only knows that Ning Dan will cross the tribulation and ascend after the ascension, and he has not even heard of the name of the realm after the ascension, let alone understand the realm after the ascension.

As for the basic methods of alchemy, as well as the common tools, they are not too complicated, as long as you have the Dan recipe, materials, Dan furnace and Dan fire, you can start to learn refining.

Tian Xu has some elixirs in his own hands, and now that he has the Medicine King Dou, it is estimated that the materials of some commonly used low-level pills should be almost there. But he didn't know anything about the other three things. Since there is a jade dish of "commonly used Danfang", it is estimated that the problem of Danfang can also be solved.

Listening to Yin Yang Ding's statement, he should be the artifact used by Emperor Shennong for alchemy back then, but I don't know if he can use it.

Thinking of this, Tian Xu asked Yin Yang Ding: "Can you do alchemy now?"

Yin Yang Ding said: "I have always been able to alchemy. It's just that I lack vitality now, and I can only work with the help of your strength, and now your ability is too weak to support my alchemy consumption at all. So you still need to find a suitable Dan furnace. The Nine Xuan Furnace you bought in the cultivation bazaar, as long as it is paired with the right Dan fire and a few furnaces of mild pills have been refined, it can almost be used. ”

Only that Danhuo has no clue yet.

The "commonly used Danfang" record is indeed the commonly used Danfang in the entry stage, these Danfang are basically one to three level of pill formulas, a total of more than 200 kinds, almost all the pills that can be used in the realm of Ning Dan and below are basically covered. As for the higher-grade pills, they were not collected here, and the reason was given: with Tian Xu's current ability, it would not be easy to refine the pills at this entry stage, and no matter how high-grade they were, they could not be refined at all, and they could not be refined if they were given, but they would affect the state of mind.

It can be seen from the pill recipe that the medicine in the medicine king bucket can at least gather nearly a hundred kinds of pill materials, which has already surprised him.

This not only records the materials of each elixir, but also records the heat and process of refining, which is very detailed. For an alchemy rookie like Tian Xu, with these pills, alchemy is a relatively easy matter.
