With Wang Xu's help, he also searched from many sources. Liu Qinghuan finally collected two foundation-building pills and one Yutan Pill.

With the three-burning Jade Dan Furnace that can improve the elixir rate, he felt that he could give it a try.

Everything was ready, and Liu Qinghuan came to the foot of Tiangong Peak.

To refine foundation building pills and yutan pills, ordinary fire spirit woods have no longer met the requirements, and they must rent the earth fire veins of Tiangong Peak.

Liu Qinghuan flew to the middle of the mountain at Tiangong Peak and landed in front of a hall built close to the mountain wall.

He put away the flying Yesuo and walked in.

The hall was empty, and behind the hall there was a cave entrance leading directly to the abdomen of the mountain. A table was placed in front of the cave entrance. The middle-aged foundation-building monk behind the table was carefully looking at a round pot in his hand.

Liu Qinghuan walked to the table and bowed: "Uncle Master, I want to rent a fire room to refine elixirs. Because it was my first time here, I wonder if Uncle Master could tell you the rules?"

The middle-aged monk glanced at him, his attention returned to his hands, and he said carelessly: "There are three grades of fire chambers that you can use, ten spirit stones in the lower-grade fire chamber in a day, twenty in the medium-grade fire chamber, and fifty in the upper-grade fire chamber. The higher the grade, the greater the maximum firepower and the more stable it is. Which type do you want?"

Liu Qinghuan pondered for a while. It was the first time he had refined the foundation-building pill. He only had two materials and was not very sure about the success rate. It was worth it if a good fire room could improve the success rate a little.

He asked, "I want to refine water-based elixirs, I don't know which one is suitable?"

"Water system?" The middle-aged monk finally turned his attention to him: "Water system alchemy is different. This sect has several special water system alchemy rooms, which are the same as the top-grade fire room."

Liu Qinghuan thought about it and said, "Then I will rent a water-based alchemy room."

The middle-aged monk whispered: "How long does it take to rent?"

"Half a month." Liu Qinghuan said, and then handed over 750 spirit stones.

The middle-aged monk took it and took out a black stone card and handed it to him, saying, "Five-story underground C23, insert this piece into the groove next to the door after entering, and then open the protective magic array. If the fire room is overdue, you need to hand over the spirit stone after you come out."

"Thank you, uncle!" Liu Qinghuan bowed and walked to the hole behind.

There is a long passage inside, with many portals on both sides, some open and some tightly closed. And on the wall of the cave at the entrance, there is a stone staircase leading up and down next to it.

He stepped onto the stone stairs, went down five floors in a row, and then walked along the passage to find B23, who had the door opened.

Liu Qinghuan walked in, looked around, and found a groove similar to the size of a stone card next to the door and inserted it in.

There was a buzzing sound, and a three-foot-thick stone door suddenly came down behind me, sealing the entire fire room, and then a thick protective light rose from the four corners.

There is a four-way ground fire outlet in the middle of the fire room. At this time, it is covered with stone slabs, and there is a carefully carved turtle head next to it. The wall in front is engraved with the entire fire room, including magic arrays, fire arrays and other control methods.

Liu Qinghuan first memorized the manipulation method, then walked to the mouth of the earth fire, and slapped it with his fingers on the stone slab twice.

The stone slab was soaked in great heat when it touched, and slowly separated to both sides. Just as a small crack was cracked, flames emerged from the crack, and a wave of heat tumbling out, and the indoor temperature rose rapidly.

Finally, all the stone slabs retreated to both sides. Liu Qinghuan made several magic tricks, and saw the burning flames on the fire mouth getting bigger and smaller as his magic tricks became, and the manipulation was very smooth.

He maintained the firepower to a stable and appropriate level, then took out the stack of three-burning jade elixir furnaces on it, and then a little bit of the head of the turtle next to it, spraying out a stream of spiritual water from the turtle's mouth, which fell into the elixir furnace.

Liu Qinghuan nodded with satisfaction, cleaned the alchemy furnace first, and had already thought about what to do next.

With a wave of his hand, a few pieces of the ingredients of the Practice Pill were placed on the surrounding ground. He was going to refine the Practice Pill first. First, be familiar with the manipulation of the earth fire, so as to avoid failure due to operational errors when refining the Foundation Building Pill. That would be unfair. In addition, he also had to cultivate the feel first.

Liu Qinghuan first refined a few spiritual cultivation pills and several other pills. He stopped until he felt it was OK and sat on the cushion beside him to restore his magic power.

He had already memorized the steps of refining the foundation-building pill, and there was no need to look at it anymore. He adjusted his breathing and kept his mind stable. Then he stood up without rushing and returned to the alchemy furnace.

Open the stone slab again and pour the five cloud water that had been prepared long ago into the San Burning Jade Pill Furnace.

Wuyunshui is a water method specially recorded in the "Shui Dan Jing Notes". Liu Qinghuan had never seen this water method in the "Taiqing Jinye Yu Dan Jing", and it should have been created by King Shui Fang himself.

This water is extremely difficult to refine. There are dozens of spiritual materials needed. Each one has different treatment methods and dosages. After entering the furnace, it is steamed and boiled three times, which is extremely troublesome to refine.

Liu Qinghuan practiced three times, and only succeeded in a total of one time, and obtained ten parts of five clouds and water.

Since it is so difficult to refine, it also shows that Wuyunshui is very powerful, not only is it better to improve the elixir rate than Muguishui, but it is said that it can stabilize the medicinal power and reduce the chance of failure of alchemy.

Liu Qinghuan had previously refined Yan Dan, but she failed several times at first. It was not until she used Wuyunshui that she succeeded for the first time. Later, she refined two more, and they all succeeded.

So today I have to rely on it to refine the foundation-building pill.

Liu Qinghuan stirred the five clouds in the furnace at a constant speed, closely observed its temperature, and put the precious spiritual medicines and materials into it in sequence.

As soon as those spiritual materials enter the furnace, some immediately turn into a pool of spiritual liquid, while others preserve their perfect shape and need to be slowly simmered.

Liu Qinghuan was fully focused and used his mind. While controlling the heat, he had to stir the five clouds quickly and slowly, and he had to pay attention to the subtle changes of various spiritual materials in the furnace.

No matter how powerful his spiritual sense was, his forehead gradually became sweaty.

Until most of the spiritual materials entered the Three Burning Jade Dan Furnace, Liu Qinghuan pointed his finger and flew over to seal the furnace and cauldron.

Only then did Liu Qinghuan raise his sleeves and wipe the sweat from his forehead. He took out two spirit stones and began to restore his magic power, but his spiritual consciousness was still paying attention to the situation in the furnace.

An hour later, Liu Qinghuan suddenly stood up and flew out in response to the sound of the stove. With his hand, he grabbed Zichuncao on the ground and he took it into his hands.

After looking at the yellow water in the furnace, he put the main spiritual medicine of the foundation-building pill in it.

This Zichun grass was obtained from Yao Yuanbing. Its leaves and stems are thick, dark green in color, and its year is more than a hundred years.

Speaking of which, Liu Qinghuan was also bold. He had another Zichun grass in his hand that was about 30 years old, but he used this century-old Zichun grass when he first refined it, and other medicines were the best.

As soon as Zichun grass entered the water, a green flame emerged from the furnace!

The green flames burned wildly, and "crackling" explosions came from the furnace.

Liu Qinghuan added the remaining medicinal materials in a row, and the stove lid flew back to cover it.

This time, the San Burning Jade Pill Furnace was not so calm, and from time to time, a dull sound like rolling thunder came out. Liu Qinghuan became nervous, and he was guarding the fireside for several hours.

Until the sound in the furnace gradually stopped, Liu Qinghuan took off the lid again, and a strong fragrance emanated.
Chapter completed!
