Han Yu didn't have any research on alchemy, and this matter could only be based on Qingteng. I can only try to cooperate with the control of Danhuo, and the difficult work of opening the furnace can only be done by Qingteng.

Han Yu communicated with Qing Teng, then pinched the magic trick and played a levitation technique towards the red furnace, making it suspend in mid-air, and let it suspend in mid-air. This spell is not difficult for Han Yu at all, precise control is a necessary skill for refining puppets, and he is very skilled. Immediately after Han Yu silently recited the mantra in his mouth, he opened his mouth and spewed out a three-color Danhuo.

At this time, no raw materials had been put into the ding, so there were not many Dan fires spewed out by Han Yu, and they were also very small, only as thick as spider silk. Then let the red furnace pot rotate slowly and be heated at a constant rate by the Dan fire. After a tea time, the red stove had turned red, exuding an astonishing heat.

Seeing this, the girl stretched out the branch in her hand, grabbed the lid of the tripod, and revealed the mouth of the tripod. Another tentacle stretched out and threw a baby's fist-sized Neidan into it, followed by rolling up the powder in seven or eight jade boxes. Seven or eight branches, in turn, put different amounts of medicinal powder into the red furnace, the movement was careful and gentle, and the dosage was controlled extremely accurately, just like an experienced alchemy master.

In this way, a third-level demon pill and dozens of auxiliary material powders required by the Lingming Pill were all poured into it, and the vines that removed the Ding Gai sent the Ding Gai back again. The first step of alchemy has been completed without any mistakes. Han Yu pinched the magic trick in his hand, and the Dan Huo in his mouth slowly changed from thin to thick, and finally became the thickness of his fingers, and the Dan Huo wrapped the Ding Furnace tightly. The flames urged the various medicinal powders of Ding, and a mysterious reaction occurred.

As time passed, Xiaoding emitted a peculiar fragrance, which made people smell for a while. Although Han Yu had never refined the Dan, he also knew that this was because the Demon Pill had been refined, and he was slowly increasing the Dan Fire that was spewing out, so that the Spirit Pill could condense the Dan at a certain moment, so that it was done. Thinking of this, Han Yu's attention became highly focused. Under the command of Qing Teng's mind, the temperature of the Dan Fire was slowly increased, and the strange fragrance in the flame was mixed with the fragrance of plants and trees, forming a charming drunken fragrance.

When Han Yu was raising the temperature in Dingzhong, Qingteng came with a divine thought to cool him down, which caught him off guard, and he quickly withdrew some of the Danhuo. But it was too late, there was a series of muffled noises in the furnace, and then a stream of emerald green gas erupted from the vent in Dingzhong, which made Han Yu's heart sink even more, and his face became a little ugly.

You don't have to look at it to know that this alchemy failed. Han Yu sighed, withdrew the Dan Fire, and opened the Ding after it cooled down. Qingteng opened the lid of the tripod and hung it upside down, dropping some white solid from the inside.

This is a mixture of the demon pill and those medicinal powders, that is, the Fei Dan of the Ning Dan that has not yet been condensed. This kind of thing is useless, and there is no way to separate the things that are mixed together. With a casual move, Han Yu swept this object into the corner. This thing is useless, it can be discarded when it goes out, it is all treasure before it enters the Dan furnace, and it is all grass once it is invalid.

Straightening the Ding furnace again, Han Yu did not continue to refine the pill, but closed his eyes and recuperated, and waited until the temperature of the Ding furnace naturally dropped, and then started again. This time, Han Yu had a long heart, and when he was almost ready to cool down, he was ready to cool down, but the divine thoughts from Qingteng made him raise his temperature, and this time the alchemy failed again.

Han Yu sighed in his heart, but continued expressionlessly. Five times...

Ten ......

After ten alchemy attempts, Han Yu's face showed a look of exhaustion, although his mana was much stronger than that of a monk of the same level, he couldn't bear such a consumption. When Han Yu stood up from the futon, a stream of flame erupted from his forehead, wrapping the Dan furnace into a fireball.

Han Yu's heart was dumbfounded for a while, it was actually the flame spirit that entered his body in the Tower of Heaven. "Let me control the temperature. A childish voice sounded in my head.

Han Yugang stood up and sat down cross-legged, looking at the flames that had not yet cooled, and was a little curious in his heart. The control of the temperature really broke his heart, and there was no law at all. Although Qing Teng mastered the skill of taking Dan, he had no way to control Danhuo into Dan, which made him feel a little anxious in his heart.

In these ten refinings, none of Han Yu was able to control the fire. He didn't feel very distressed about the wasted materials, but he was a little anxious, and planned to try it in a few days. Anyway, I brought so many materials, and when I failed all, I gave up, and when I was advanced to the later stage of cultivation, I tried to try the skills of controlling the Danhuo. But at this moment, the fire spirit that had been infiltrating his body emerged from this moment.

Han Yu watched the red furnace being wrapped into a fireball, and Qingteng put all the materials into it, and with the tacit understanding of increasing and decreasing the temperature, at an extremely mysterious time, the Ding furnace opened, and a medicinal fragrance permeated. Han Yu was dumbfounded, and then with a move of his hand, he took the steaming red furnace in front of him, and stretched out his head to take a look.

There was a crystal clear pill lying inside, this was the Lingming Pill he had ever seen, which was larger and the medicinal fragrance was stronger. This made Han Yu's mood greatly uplifted.

As a spirit of flame, the spirit of fire is very good at controlling the temperature, and Qingteng's spiritual planting talent also has a certain spiritual reaction to the formation of the pill in Dingzhong, which is really a match made in heaven. With this successful example, Han Yu put all the materials on his body in this secret room and instructed himself to come to the quiet room next door.

Han Yu had dozens of bottles of pills on his body that were beneficial to his cultivation, enough for him to use in his retreat. It is rare to have time, and he plans to retreat here for a period of time, to comprehend the mind of the Taishang Origin, and see if there is any chance to impact the realm of the later stage.

Sitting on the stone bed in the secret room, Han Yu took out a white porcelain vase from the storage bag. Then he poured out a blue-glowing pill from it, put it into his mouth with one hand, and swallowed it.

From the Danhuo slowly refining the medicinal power, feeling a slight heat in his abdomen, Han Yu silently recited the mental mantra in his mouth, closed his eyes and slowly cultivated. Time flies, and three years pass in the blink of an eye.

Han Yu slowly opened his eyes, feeling the surging mana in his body, but he couldn't help but sigh in his heart. There is always a layer of shackles in the later realm, which seems to be easy to break, but this opportunity has always been lacking.

Han Yu sighed, feeling a little depressed in his heart. If you want to break through this shackle, it is easy to say that it is difficult. It is possible to have a slight understanding and a successful breakthrough in the heart of the mountains and rivers, or it may be the line of life and death in the fighting method, or it may be a little bit of a sense of the bypass, and there is no law to be found at all.

After Han Yu left the customs for a short time, he went to the alchemy room to see how the progress was going over there. When he entered, he was stunned to see that the materials in the foundation building period on the ground had turned into elixirs.

Opening the furnace alchemy is the most difficult thing to refine in the rumors of the immortal cultivation world, and those alchemists have to go through dozens or hundreds of times to refine the elixir, how can it become so easy here. A glance at the waste pill in the corner, although it was also piled up into a small pile, it was not worth mentioning at all compared to the rumors. Han Yu's heart was a little confused.

However, thinking about the process of controlling the Dan Fire during the ten times he refined, Han Yu felt that the rumors were not exaggerated. This really made Han Yu guess right. Alchemy is actually a little more difficult than what is advertised, an alchemist who can refine the elixir of the Dan period will have to spend almost a lifetime of energy, and the forces behind it will spend almost astronomical wealth to cultivate it if the talent is sufficient.

The two most difficult points are Dan and Flame Control, which are too simple for the two Flame Essence and Qing Teng, almost instinctive existence. What Han Yu prepared this time was all Danfang for the foundation building period, and there was not a single Dan for the Dan period, and the raw materials were not prepared.

He didn't expect such a play. However, the Danfang and raw materials in the Dan period are not available everywhere in the foundation building period, they are all in the hands of some big forces of the Great Gate Sect, and it is not easy to obtain them.

Han Yu slaughtered the Xu family monk and also got one, but it was only a pill recipe in the early stage of the Dan, and the materials required were very cumbersome, and Han Yu had no intention of refining it.
