Mana without attributes also means that there is no spiritual root, how can a person who doesn't even have a spiritual root cultivate mana.

Chen Jinnei was also shocked when he looked at his mana, why was his newly practiced mana exactly the same as the power of chaos, but it had no attributes but seemed to contain all the attributes, and it seemed to restore everything.

It's a pity that this mana can only be used as ordinary mana, and Chen Jin still doesn't know much about this mysterious mana.

"Forget it, no matter what, in short, this trial trip is a huge gain." Chen Jin muttered to himself.

Chen Jin turned over and stopped cultivating, although the cultivation speed with the spirit stone was very fast, but the aura in the spirit stone would not be directly transformed into mana, and it still needed to be refined by himself to transform into mana, and only the pill could quickly convert the medicinal power into mana.

So Chen Jin went to Banfang City, bought a pill and the medicinal materials he needed, and then began to prepare for alchemy.

Alchemy is the same as refining, the more times it is refined, the greater the success rate, refining is nothing to Chen Jin, it is easy to practice good magic weapons with a factory assembly line, but alchemy is different, and the success rate of each pill is different. That is to say, if you refine the Hua Dan and are a master, if you change the Huanglong Dan, you will be a newcomer again, of course, because of the experience of refining in the front, it is unlikely that there will be low-level mistakes in the back.

Because of this reason, even the masters of the Alchemy Pavilion of the Xintan Sect did not dare to refine all the pills to be 100% successful, and what they could guarantee was only a few that they were better at.

For a newcomer who has never practiced pills, the most fundamental difficulty is that there are not so many alchemy materials for you to practice. Although the price of medicinal materials is high and low, the number of refining is too much, especially the high-quality pills, the auxiliary medicinal materials are not counted, not counting just a few of the main medicines, then it will cost hundreds of thousands of spirit stones, even if it is an ordinary small sect or immortal cultivation family, at most, it will only cultivate one or two alchemists, and if you cultivate a few more, you can't afford to cultivate it at all, this is also the reason for the abundance of resources in the fairy world, and then look at the hundreds of millions of people in the god clan on the earth, there are not a few alchemists.

???? However, this problem is not a problem for Chen Jin. First of all, how many spirit stones he wants, it's just that he is not good at using them as a new disciple who has just started, and secondly, he has mysterious silt, with this thing, how many spirit herbs and elixirs do you want? The key is that as long as there are seeds or even a root system, he will soon be able to cultivate a large number of spirit grass elixirs, even if the spirit grass is tens of thousands of years old, it is not too much of a problem for him.

Next is the most important thing, if you want to refine alchemy, you have to have a very important thing, that is, Danhuo. Without a suitable Danhuo, the success rate of alchemy and the quality of the Dan will still be much worse. Although there is an earth fire in the alchemy room, Chen Jin doesn't want to use it, joking about how good the earth fire is in the residence of an outer disciple.

Don't worry about it at all, Chen Jin is a person in the world of science and technology, the artificial sun project has already been completed, and even the equipment has been compressed to the point where it can be carried around. Of course, it is useless to have fire, and the person who has to refine the pill has a certain degree of grasp of the fire, and the fire is not good if it is a little bigger, and the pill will be refined into a pitch-black residue; If the fire is too small, it will not work, once it is time to come out of the pill, if the pill is not released, the medicinal effect will be lost, not to mention, the refining is still a waste pill; The flame is strong or weak, and it is even more unstable, not only can the pill not be refined, but there will even be a risk of exploding.

However, Chen Jin doesn't need to worry about fire control at all, he only needs to use the control equipment to set the temperature, the thermostat will help Chen Jin master the fire very well, others always have to experiment and practice countless times to control the fire, and the hard work of the next few years can't be controlled at all, and even the fire can't be controlled, how to alchemy, but it is too simple for Chen Jin.

Chen Jin sat down cross-legged, connected and controlled the artificial sun device with the chip in his brain, and then released a few wisps of fire, as soon as the flame converted into the energy generated by nuclear fission came out, the temperature displayed in the thermostat increased at an incredible speed, only reaching 100,000 degrees in an instant, but the temperature in the room did not increase in the slightest, which shows that the effect of the equipment in isolating heat has been very perfect.

Chen Jin also knew that such a high temperature would not be able to connect the Dan at all, even if the Dan furnace was put in, I was afraid that the Dan furnace would melt into iron juice in an instant, or there would be nothing vaporized in two or three seconds. Chen Jin could only slowly lower the temperature, and when the temperature stabilized at two thousand degrees, Chen Jin turned on the equipment and put it into the alchemy furnace, this temperature is the best for practicing some low-grade pills.

Heavenly Spirit Grass, Spirit Beast Bones, Centennial Spirit Liquid, and some medicinal herbs...... Successively threw these auxiliary materials into the burned hot Dan furnace, and it didn't take long for them to be melted into a viscous liquid, these are all auxiliary materials, so there is no need to refine them separately, the heavenly spirit grass was melted into a blue-green liquid, and the bones of the spirit beast were turned into milky white mud, and after the spiritual liquid was poured into the Dan furnace, it was scalded and thickened more and more, but it also protected other medicinal materials and let the juice of other chemical materials float on it, so as not to make the medicinal materials burn black.

At this time, Chen Jin's mana penetrated in, and after a few gentle stirrings, he saw that several colors of liquid were mixed together, fused with each other under the action of temperature, and it looked like various colors of paste mixed together.

After the heat lasted for a while, the various colors of paste were already mixed together, and the color could no longer distinguish between you and me, but as time passed, the surface of the liquid became thicker and thicker, and particles began to bubble out of the bubbles.

These granular things are impurities, Chen Jin's mana controlling the wood attribute slowly entered the Dan furnace again, and used the mana to hold up those impurities and slowly rise into the air, but before they rose for long, the tiny impurities turned into dust in the high temperature and drifted to the sky.

The time for alchemy was long, half an hour, and all the hybrids in the liquid in the Dan furnace had been eliminated. After the auxiliary materials are refined, the main material is the greasy dragon beard grass that Chen Jin ate, and this pill recipe was also chosen by Chen Jin when he saw that the main material was dragon beard grass, otherwise any other pill main material was not something he could afford with the money on the surface.
