"This is the forbidden token of the alchemy room, after entering the alchemy room, just insert the token into the groove next to the door, and the stone door will automatically close, unless the senior nephew comes up with it himself, no one can disturb you, but the junior brother's cultivation is low, don't do what you can't do." After Jia Gui took over the five lower grade spirit stones, he handed a forbidden token to Liu Bin and reminded him.

"What can't be done?" asked Liu Bin puzzled.

"There was a junior disciple before, who cultivated like you, and entered the No. 3 alchemy room, but when the spiritual power was exhausted when it came out, I still carried him out!" Jia Gui explained, the meaning of his words was obvious.

"Okay, I got it!" Liu Bin smiled.

"Well, there are eighteen alchemy rooms here, all of them are empty now, and the firepower is also arranged from weak to strong, the more you go inside, the stronger the firepower is, the junior nephew can choose by himself, I wish the junior brother success in alchemy. Jia Gui pointed in the direction of the alchemy room and explained.

"Thank you, Senior Brother Jia. Liu Bin thanked Na Jia Gui and went straight into Danhori.

After Liu Bin entered Danbori, he felt that the heat wave was coming, and he immediately raised his spiritual power to resist, and his body was a little cooler.

There are nine alchemy rooms on the left and right sides of the Danhori inside, this is the first time to use fire to alchemize, Liu Bin doesn't know what the difference is between earth fire and fireball flames, so he didn't choose the alchemy room with too much firepower, but entered the alchemy room marked with the number three.

After entering the No. 3 alchemy room, he inserted the forbidden token given by Jia Gui into the groove at the door, and the stone door was closed in an instant, and a certain formation in the alchemy room was opened, cutting off all contact with the outside world, and he used his spiritual sense to probe the confinement that could not penetrate the formation.

Liu Bin took the token out of the groove, the formation ban was immediately lifted, and the stone gate slowly rose, and he couldn't help but sigh at the ingenuity of making this mechanism, it seems that this is an excellent place for alchemy cultivation, Liu Bin nodded with satisfaction, and put the token back into the groove.

Suddenly, I felt that the charge for five lower-grade spirit stones was not very expensive, the Dan room was not big, only thirty or forty square meters, and in the middle of the alchemy room, a Dan furnace was prepared, but the grade was not high, it was just a low-grade alchemy spirit weapon.

Take the Dan furnace away, there is a scorching earth fire below, the flames jump, reflecting Liu Bin's whole face is red, and he stretched out his hand to feel the temperature of the flames, which is a few points higher than the heat generated by the fireball technique.

Jia Gui said that the further inside, the higher the temperature of the earth fire, Liu Bin was a little impatient and wanted to take a look.

Put the lower pin dan furnace aside, and take out the Liuhe Dan furnace purchased in Panlongfang City from the storage bag.

Sitting down cross-legged, Liu Bin took out all the spiritual herbs that had been prepared in advance to refine the Qi Replenishment, and used them to familiarize himself with the earth fire, preparing for the refining of the Seven Holy Pills, and at the same time wanted to verify the experience in the notes of Chi Lingzi in the past six months.

Liu Bin stabilized his mind, made all the preparations, and placed the Liuhe Dan furnace at the source of the earth fire, so that the earth fire could radiate the entire bottom of the Dan furnace.

"Get up!" Liu Bin hit the Dan with his hand, and a stream of spiritual power flew to the Dan furnace, and the lid of the Dan furnace slowly opened.

Liu Bin put the materials for refining Qi Replenishment into it, looked at the Dan furnace that had been almost filled, and took a deep breath.

Then the Dan Jue of both hands changed and changed, and a stream of pure spiritual power was struck, and the lid of the Dan furnace was slowly closed, and at the same time, the Liuhe Dan Furnace was running rapidly on the ground fire.

In the alchemy room, Liu Bin began to implement it step by step, and did not rely on the fact that he could already refine the fourth-order spirit pill and be negligent, melting the spirit medicine, condensing, and finally injecting spiritual power, with each Dan duel, the flames around the Dan furnace became a little brighter, and the scorching breath was emitted from all sides, and there was a smell of burning the air.

It is conceivable that under Liu Bin's urging, the flames under the Dan furnace almost entered the strongest level in the shortest time, casting the Dan Duel, controlling the ground fire to burn evenly around the Dan furnace.

The same amount of materials, refining the same elixir, if the intensity of the flame is not the same, the quantity and quality of the refined elixir are also completely different, the earth fire is well controlled, the more the number of pills refined, and the better the quality.

This is what Bing Yu told Liu Bin before, but he only had the opportunity to try it today.

At the same time as Liu Bin's last Dan duel, he also reached the final stage of alchemy, and only a muffled sound was heard in the Dan furnace.

As the muffled sound ended, the Dan furnace slowly stopped rotating, and Liu Bin hurriedly stepped forward to check the results of his first alchemy.

The moment the lid of the Dan furnace was opened, Liu Bin was stunned, and a burning smell immediately drilled into Liu Bin's nose, and the materials in the Dan furnace turned into ashes, and there was no single replenishment of qi, and it failed.

"it!"

Liu Bin sat on the futon and looked at the residue in the Liuhe Dan furnace, secretly glad that he did not directly refine the Seven Holy Pills, it seems that this earth fire still needs to be slowly adapted.

For an alchemist who could refine a fourth-order elixir, it was not surprising that refining a low-order elixir failed, after all, no one could guarantee a 100% success rate.

Calming down, Liu Bin carefully thought about each step just now, and summed up the experience of failure, it should be the heat of the earth fire, which is stronger than the heat emitted by the fireball, and the fireball technique is performed by the monk, and the earth fire is also a spiritual fire, and the alchemist can only use the Dan decision and time to control the degree of the flame, so it is more complicated.

In the quiet alchemy room, Liu Bin walked around the alchemy room a few times.

"Come again!"

This time, Liu Bin didn't put so many materials, and the failure rate of alchemy was uncontrollable, so he had to save the elixir materials.

This time, Liu Bin only put in the amount of refining a Qi Replenishment Dispersion, and carefully cast the Dan Decision step by step, changing the temperature of the earth fire and controlling the length of time.

This is already the third time he has refined the replenishing qi dispersion, nervously opened the Dan furnace, and the moment the lid was opened, Liu Bin smelled a fragrance and knew that it had succeeded.

Seeing a Qi Replenishment Disperse lying quietly in the Liuhe Dan furnace, Liu Bin took out the vial prepared in advance, put it into the bottle, and looked at the brown pill in the bottle, Liu Bin smiled.

From the luster and smell of the surface of the replenishing qi dispersion, Liu Bin knew that this pill belonged to the top grade, although it was only a first-order elixir, but the medicinal effect was absolutely not to be said, it was definitely worth the money, and it was definitely very popular when it was sold on the market.

This success gave Liu Bin great confidence, Liu Bin quickly sat down, put a qi replenishing material into the Dan furnace, and performed the Dan decision according to the same steps.

Liu Bin tirelessly refined, the essence is not too expensive, refining one by one, what he wants is the successful Dan rate, and the feeling of being integrated with the earth and fire.

At first, there will be one failure in five or six times, then one failure in more than ten times, and in the end, there will be basically more than thirty consecutive failures without a single failure.

As the replenishment of qi in the bottle slowly increased, and the materials were used less and less, Liu Bin completely mastered the characteristics of earth fire.

Don't look at the refining of low-level spirit pills, it is also very spiritual power-consuming, fortunately, Liu Bin is a late stage of Jindan's cultivation, otherwise it is really as Jia Gui said, if you do something beyond your strength, you will be laughed at and generous.
