Of course, alchemy has extremely high requirements for the amount of each elixir, and it can't be more or less, even a little error can lead to drastic changes in the medicinal properties of the pill, and the powder he put into the Dan furnace is just a quantity.

With all the medicinal powder added to the Dan furnace, Jiang Yu closed the lid, and this second step was finally completed perfectly.

I have to say that Jiang Yu has some ways in alchemy, and every Dan Master needs to figure it out little by little when he tries alchemy for the first time, and it is impossible to do it in one go.

The third step is the mixing of the control zhì medicinal powder, this step is the most important step of all the steps, and if one is not good, it will fail.

Under the baking of the earth fire, the Dan furnace exudes a terrifying high temperature, but fortunately, the Dan furnace is not made of ordinary materials, otherwise this Dan furnace will probably turn into liquid in an instant.

It was hard to imagine how high the original temperature of this earth fire was, these flames were still artificially treated earth fires, and after feeling the burning sensation from the Dan furnace, Jiang Yu hurriedly suppressed the temperature of the flames.

Time passed, and there were already bursts of medicinal fragrance in the Dan furnace, Jiang Yu was overjoyed, he knew that this pill had already succeeded halfway, as long as there was nothing wrong with the Dan Condensing Pill, it could be said that the refining was successful.

Thinking of this, Jiang Yu was in a good mood, and the purple earth fire in the furnace showed a whirlpool state, and there was a light yellow pill flipping up and down in the center of rotation.

After a while, there was a cracking sound in the Dan furnace, followed by a burning smell, Jiang Yu shook his head helplessly, this first alchemy was a failure. With a wave of the embroidered robe, he took out the residue in the furnace, and the residue of the elixir in the furnace had been burned into charcoal-like storage.

After summarizing the reasons for the failure, Jiang Yu began the next round of alchemy.

In the blink of an eye, Jiang Yu had been in the alchemy room for nearly three months, and Jiang Yu had been doing the same thing for these three months, that is, alchemy. Fortunately, his mind is far different from ordinary people, otherwise a person who repeats the same thing all day long is afraid that he will go crazy on the spot.

Jiang Yu has been refining Bigu Dan for three months, and after burning more than ten elixirs, Jiang Yu finally succeeded in refining a Bigu Dan, and with Jiang Yu's continuous practice, the probability of Ning Dan's success is getting higher and higher.

After spending thousands of copies of refining the elixir of Bigu Dan, the chance of success in refining Bigu Dan has reached ninety percent!

Because Jiang Yu has refined thousands of Bigu Pills, he doesn't have to worry about energy consumption, as long as he has a sense of hunger, Jiang Yu will take Bigu Pills.

Unconsciously, Jiang Yu had already spent two years in the alchemy room, and because of the alchemy all day, his skin had a different kind of luster. Two years have made Jiang Yu a lot of changes, he is a lot stronger, and there is a faint glow in his eyes.

Because Jiang Yu had been in the alchemy room for nearly two years, the old man who was guarding the alchemy room had already been anxious, although it was normal to practice alchemy for a year or two, but he, Jiang Yu, was just a teenager, did he know that he could last for two years?

The old man thought it was impossible, and there were several times when he wanted to enter the alchemy room to check it, but he couldn't get in because of the formation in the alchemy room.

In the past two years, Jiang Yu has refined more than ten kinds of pills, and countless low-grade medicinal materials have been consumed, usually bundles of elixirs are used to practice.

At the beginning, Jiang Yu wanted to refine the Barrier Breaking Pill to improve his cultivation, but as early as a year ago, when he was refining the Pill, he accidentally broke through the bottleneck, perhaps because his spiritual power was too strong, and after breaking through the bottleneck, he actually reached the peak of the fifth layer of Qi refining, and he was only one step away from the sixth layer of Qi refining.

In this way, Jiang Yu put the main direction of alchemy on the aspect of improving cultivation, and Jiang Yu refined thousands of pills like Qi Refining Pill.

Even Jiang Yu's spiritual power relied on pills, and the spiritual power in his body began to transform into a liquid state after repeated times.

With the cultivation of the Tao Sutra, the appetite of the Dao Sutra is also increasing. Jiang Yu's spiritual power at the fourth layer of qi refining was comparable to that of a monk at the sixth layer of ordinary qi refining, and now that he had reached the fifth layer of qi refining, he could already compare to the peak of the sixth layer of qi refining.

In recent months, he has successfully refined the Peiling Pill, and after several attempts, he finally increased the probability of the Pill to about sixty percent, and the probability of this Pill Transmission Pill is already very high for the Peiling Pill.

Take his cheap master as an example, refining ten times to be able to succeed in cultivating the spirit pill three times is already very good, not to mention the success rate of sixty percent.

Because the main medicine for refining the Pei Ling Pill has been used up, otherwise Jiang Yu wouldn't want to go out!

"It's time to go out, I don't know how long it's been. "These pills are enough for Jiang Yu to cultivate to the seventh level of qi refining, but Jiang Yu is still not happy, he can progress Wang Li is also improving, Jiang Yu's pressure is still very great.

At this time, the old man who was guarding the alchemy room couldn't bear it anymore, Jiang Yu, a junior at the fourth level of qi refining, couldn't stay in the Danfang for two years, even if the foundation building monk stayed in the Danfang for two years, he should have to come out, and the old man was sure that something had happened to Jiang Yu.

At this moment, the stone door clanged, and a young man in a white robe walked out of it.

The breeze came, the long hair moved with the wind, and the young man's face revealed a bit of bookish freshness!

This person was Jiang Yu, who had just walked out of the alchemy room, and after two years, he finally saw the outside world.

"Thank God, you're finally here!" The old man sighed deeply, because Jiang Yu hadn't come out for two years, he privately inquired about Jiang Yu's identity.

When he knew that Jiang Yu was the registered name of that Li Tianyuan, the old man couldn't sit still, although Jiang Yu was only a registered disciple, but that Li Tianyuan was a well-known protector in Panlong Valley, as long as something happened to Jiang Yu, then he couldn't get out of it, and he was a manager of the sixth layer of qi refining who would definitely not be able to resist that kind of anger.

"Hey, you've reached the peak of the fifth layer of Qi refining!"

"I refined some pills before, but I was lucky enough to get rid of them. ”

"I'm afraid that it won't be long before we will be called peers, congratulations to Senior Nephew Jiang first. "Jiang Yu is now at the peak of the fifth level of Qi refining, and the spiritual power in his body is extremely strong, how can the old man not feel it. If Jiang Yu could break through to the sixth layer of qi refining, it would not be difficult to be accepted as an inner disciple.

"I don't know how long I've been in there!"

"It's been more than two years!" Jiang Yu's face revealed a look of shock, after paying more than twenty spirit stones, Jiang Yu left in a hurry, even he didn't expect to stay in the alchemy room for so long.

Jiang Yu had been away from the medicine garden for two years, and he didn't know what happened to those elixirs, in case Li Tianyuan came back, it would be difficult to do. Although Jiang Yu didn't know what Li Tianyuan's purpose was, the cheap master had just taken him as an apprentice for the sake of elixir.

Those elixirs have not been taken care of for two years, and there may be some mess. Jiang Yu was not afraid that the elixir would grow too badly, but that the elixir would grow too well!
