After watching Yan Tianzhen refining the "Returning to Heaven and Replenishing Yuan Liquid", Hua Yu had a deeper understanding of the art of alchemy.

The origin of alchemy, which can be traced back to the beginning of the germination of the path of cultivation, can be said to be a very ancient knowledge inheritance, after the development from ancient times to the present, the art of alchemy has become a very extensive knowledge system, infiltrating all aspects of the monastic world, and is closely related to every cultivator.

Alchemy and alchemy can be said to be closely related, but they can also be said to be two different directional systems.

It is said that it is closely related because both of them study the attributes of various spiritual materials between heaven and earth, and refine them into various elixirs and elixirs to assist cultivators in their cultivation.

The reason for the difference between the two is that alchemy and alchemy follow two different research directions. Alchemy is mainly the study of the attribute collocation between various spiritual materials, focusing on the excavation of the characteristics of the spiritual materials themselves, while alchemy also studies the attribute collocation between spiritual materials, but it only uses various spiritual materials as the introduction of alchemy, to gather the spiritual machines of heaven and earth, and the laws of Dao rhyme.

Therefore, in the study of spiritual materials, alchemy takes the road of breadth and breadth, while alchemy takes the path of refinement and depth.

If you compare the two, in fact, there is no higher or lower than the breadth and profundity. It's just that alchemy may be easier to master, and refining elixir is much more convenient, but Hua Yu feels that alchemy consumes too much resources, because alchemy itself is to tap the attributes of the spiritual material itself, and it is not okay to have a small amount. At this point, alchemy is not as good as alchemy, and the spiritual materials required for alchemy only serve as an introduction, so the amount required is much less.

This is also due to the birth of alchemy and the abundant resources of the Yuan Dynasty, when the heavens and the earth were full of all kinds of heavenly and earthly treasures, not at all like now, all kinds of heavenly materials and earthly treasures are hard to find.

In today's era of gradual scarcity of resources, alchemy seems to be more in line with the development trend of the times, more conducive to the development of the entire monastic world, and in line with the general trend of the development of the world itself. This is also one of the important reasons why Hua Yu is determined to create alchemy.

...

After sorting out his new perception of alchemy and alchemy, Hua Yu left the Elixir Valley and returned to his own mysterious small building.

As soon as he returned to the cultivation room, before he could sit down, a ball of white flesh* crashed into Hua Yu's arms.

"Xiao Ao, you guy" Hua Yu stroked the little white beast in his arms and said helplessly: "Didn't you tell you not to do this, ordinary people can't stand your collision like this."

After hearing Hua Yu's complaint, the little beast's eyes turned smartly, and then jumped from his arms to Hua Yu's shoulder, constantly rubbing Hua Yu's neck with his little head, revealing a flattering and affectionate appearance.

Seeing the little beast like this, Hua Yu couldn't help but take it off his shoulder and hold it in the air and said, "You guy, you have actually learned to be coquettish, and if you are disobedient, you will be deducted from your rations!"

The little beast heard that the rations were going to be reduced, and it was okay, Hua Yu specially made all kinds of beast food full of heaven and earth vitality for it, which was its favorite, so it struggled to jump from the air, and lay down obediently in front of Hua Yu very doglegs, opening a pair of smart and innocent eyes, as if to say: "I will obediently listen to you, don't deduct my rations."

"Haha..."Hua Yu was amused.

...

After playing with the little beast for a while and relaxing his spirit, Hua Yu lay quietly on the cloud bed in the cultivation room, thinking about his next plan.

At present, all kinds of basic knowledge within the scope of planning have basically entered the right track, and it is not possible to go further in a while.

Therefore, the next most important thing is to obtain cultivation resources and accelerate the speed of cultivation. This is because no matter what aspect of cultivation is inseparable from the help of various resources, and even aspects such as refining medicine and refining tools can be said to be completely piled up with resources.

Therefore, Hua Yu prepared to travel down the mountain. First, it is better to travel thousands of miles than to read 10,000 books, and travel can broaden your horizons, put what you have learned into practice, and verify your own achievements; second, you can also do some sect tasks, and by the way, you can obtain various resources needed for cultivation during your travels.

"That's it," Hua Yu sat up from the cloud bed at once, and then muttered to himself, "However, before traveling, there is one more important thing to do."

This important thing is about refining the natal magic weapon. There is a mysterious Xuanhuang Qi in Hua Yu's sea of consciousness, which was obtained by entering a mysterious space when he was enlightened. For this treasure that could shake the entire cultivation world if the news was released, Hua Yu was ready to refine it into a natal magic weapon.

The most important thing is to carry the fundamental avenue of the cultivator, which may not be the most powerful and powerful treasure in the hands of the cultivator, but it is definitely the treasure that is most suitable for the cultivator himself.

Whether it is an innate refining weapon or an acquired refining weapon, it can be said that it has its own advantages and disadvantages. The magic weapon refined by the innate refining weapon has greater potential, but it is not easy to find a material that matches the attributes of the cultivator's avenue;

And Hua Yu is going to use Xuanhuang Qi to refine the natal magic weapon, which can have the advantages of both innate and acquired refiners. Xuanhuang Qi is the essence of heaven and earth, which can evolve all things in heaven and earth, and itself has the advantage of being ever-changing.

If the Xuanhuang Qi is refined into the natal magic weapon with the innate refining technique, then the natal magic weapon not only has the advantages of the innate magic weapon, but also because the Xuanhuang Qi can evolve the characteristics of all things in heaven and earth, it can make it develop in the direction of conforming to the Great Dao, just like the acquired refining weapon that is completely controlled by the cultivator, and does not need to be subject to the properties of the material itself like other innate magic weapons.

The unique advantage of Xuanhuang Qi is the best material for refining the natal magic weapon, which is the result of Hua Yu's extensive research. In the Daozang Peak Daoist Academy, there are many ancestors of the sect who have various interesting ideas about the Xuanhuang Qi according to the characteristics of the Xuanhuang Qi, among which there is the idea of using the Xuanhuang Qi to refine the natal magic weapon, but most of the predecessors of these sects have never seen this kind of magical thing, and most of them are just conjectures. Hua Yu was fortunate enough to get this kind of treasure, so naturally he couldn't give up this tempting attempt.

However, before officially refining the natal magic weapon, Hua Yu also had to try the Xuanhuang Qi first.

The mind sank into the ancestral aperture of the eyebrows, and at the top of the sea of spiritual consciousness was suspended a cloud of ethereal and ever-changing Xuanhuang qi.

Hua Yu tried to control this mass of Xuanhuang Qi, and under the control of Hua Yu's spiritual power, the Xuanhuang Qi mass fell from the top of the sea of knowledge, and changed into various things according to Hua Yu's spiritual thoughts, which was actually very easy to control.

Then, Hua Yu tried to separate some Xuanhuang Qi from this Xuanhuang Qi, but he did not succeed, as if this Xuanhuang Qi was an inseparable whole.

This is not possible, Hua Yu kept trying to use various methods to separate some Xuanhuang Qi from this mass of Xuanhuang Qi. In the end, with the help of the Mingyu Disc composed of Tai Chi Yin and Yang Dao Yun in the Sea of Knowledge, Hua Yu struggled to separate a small mass of Xuanhuang Qi from the whole, which was less than one percent of the whole.

Hua Yu lured this small amount of Xuanhuang Qi out of his body, causing it to levitate in front of him. However, when this small group of Xuanhuang Qi appeared in the outside world, suddenly the Dao rhyme in the cultivation room converged, the Dao sound bursted, the strange fragrance was fragrant, and all kinds of visions resonated with heaven and earth.

When Hua Yu's vision did not further expand, he was frightened and hurriedly withdrew it into the sea of knowledge. Even so, there were still a few places in the Taixuan Sect that made startled sounds, and they all spread their divine thoughts, as if they were looking for something.
