Su Chen had already raised a pair of spiritual herbs for building the foundation pill in his hand, but he still needed to have a Jindan-level alchemy furnace and an extremely high temperature furnace.

There is a thousand-year-old spirit medicinal herb in this Zhuji Dan medicinal material. Such a high-grade medicinal material, relying on the flame of a low-level Qi refining cultivator, and even the true fire of a foundation building cultivator, cannot be refined, it must be a true fire above the third order. It is best to use pure samadhi fire to refine this medicine.

And this samadhi true fire can only be released by the fire type Jindan monks, as Jindan monks, they will not waste time helping the Zhuji monks to refine the pill, they can only find a way to solve it by themselves.

However, Su Chen knew that the alchemy master Wang Qiu had once refined a third-order elixir at the Jindan level, and since Wang Qiu could do it as a foundation building cultivator, there must be a way to solve these two problems.

He arrived at Wang Qiu's residence, visited him, and humbly asked Wang Qiu for advice on how to solve the problem of high temperature furnace fire.

Wang Qiu rarely interacts with the monks of the same sect on weekdays, and he has a good impression of Su Chen, who is also a casual cultivator and worships the Immortal Sect.

"Senior Brother Su, when refining elixirs in our Penglai Immortal Sect, we never worry about the source of fire, and there is a special large-scale alchemy room that can refine various grades of elixir.

I have prepared a pair of third-order medicinal materials and a third-order medicinal material in the past few months, and I am about to go to alchemy, so you can go with me. I will take you to the holy land of alchemy and refining of our Penglai Immortal Sect - Copper Furnace Mountain. ”

He went out with Su Chen, and Edgeworth headed to Copper Furnace Mountain.

"By the way, Senior Brother Su, what alchemy level are you now? If you are an alchemy apprentice, it is best to find an alchemist to learn the art. With the divine mind and control of the foundation monk, it only takes one year to complete the apprenticeship. After refining to the alchemist, he can become a master and can do alchemy independently. ”

"Before, in Chaoge City, I used to refine some of the lowest-level first-order Linglu Pills, so I should be regarded as an alchemist. ”

Su Chen thought for a moment and said.

He didn't say that he had refined a low-grade marrow cleansing pill, which was very rare, second only to Zhuji Dan.

Before this marrow cleansing pill reached the realm of an alchemy master, no alchemist dared to touch it at all.

It's not that it can't be refined, but that the cost is often much higher than the benefit. Even refining the lowest-grade marrow cleansing pill would consume a large amount of expensive medicinal materials, and if there was a slight mistake, the family would go bankrupt.

Su Chen was self-aware, his alchemy technique was not very clever, and he completely relied on himself to grow extremely low-cost elixir materials in Lingshan, and only at any cost did he refine a small amount of low-grade marrow cleansing pills.

According to estimates, he should be higher than most alchemists, almost at the level of alchemists. However, he is still modest and low-key, and considers himself an alchemist.

"Since you are an alchemist, you can directly open the furnace for alchemy! The art of alchemy does not have it, spend more time pondering, practice makes perfect. The old man doesn't have much talent for alchemy, and he immerses himself in it day and night, often thinking about tea and rice, and turning day and night upside down. But after thirty or forty years, he has become an alchemy master!"

Wang Qiu understated, quite like an alchemy master, and pointed out Su Chendao.

But he knew very well how difficult it was to cultivate alchemy.

The most difficult part of the improvement of alchemy is the "Spirit Stone". Once a furnace of spirit materials was refined, hundreds or thousands of spirit stones would be wiped out at every turn.

The vast majority of alchemists spend their energy on collecting spiritual materials, and they often have the opportunity to refine a furnace of spiritual pills after a month or two.

The profit of the elixir industry is also quite high.

But if the level of alchemists and alchemists is not enough, they will always lose more and earn less. The alchemist will definitely lose, and the alchemist will only barely be able to keep his capital.

When an alchemist cries poor, it is definitely a normal thing.

Only when you reach the realm of alchemy masters can you really breathe a sigh of relief and start to enter the time of earning great spirit stones. Of course, this refers to refining those low-level first- and second-order elixirs.

If the alchemy master went to refine the third-order spirit pill, it would still be a loss to vomit blood. Refining a pair of third-order pills, the lost spirit stones, at least half a year can not breathe.

...

Wang Qiu took Su Chen and flew with his sword in the Penglai Immortal Sect.

With the speed of Monk Tsukiji's sword, it still took the two of them a full half an hour to reach a crimson mountain that was bare and treeless for hundreds of miles around.

When Su Chen saw the crimson peak, he was immediately stunned.

It turned out to be a mountain with flames, and the crater erupted with smoke, molten lava, and flames. There were brimstone and flint everywhere.

"It's... Volcano?"

Su Chen was surprised.

He suddenly understood why Wang Qiu wanted to come to this place.

"This mountain is indeed a volcano, and it is called Copper Furnace Mountain. This is the only volcano in my Penglai Immortal Sect, and it is this mountain that greatly facilitates us and other alchemy and refining cultivators, and we don't have to worry about the source of fire. Even some fire-based cultivators stay here every day to cultivate, absorbing the rich fire aura!"

Wang Qiu couldn't help laughing when he saw him shocked.

Monks who are new to this place will inevitably be shocked when they see such a large mountain on fire.

The two of them flew down on the peak of the copper furnace mountain.

But I saw a huge cave in the center of the mountain peak, which was thousands of feet deep, and it was bubbling with raging fire.

The entire copper furnace mountain is like a burning giant copper furnace between heaven and earth, the molten slurry in the depths is like a large pot of boiling copper juice, and the temperature of the flame is extremely high, even purer than the true fire of samadhi.

Standing at the mouth of the mountain peak, Su Chen felt a scorching flame breath, rushing towards his face, and the heat wave could almost burn his clothes.

Around this crater, many disciples in the Qi refining period set up alchemy furnaces and refining furnaces, guiding the raging earth fire, burning the alchemy furnace and refining furnace.

Many strong men in the Qi refining period wielded a huge iron hammer, shouting loudly, beating all kinds of spirit knives, spirit swords and spiritual weapons, bare-chested and exposed, sweating profusely.

"The temperature of this earth fire is very stable, and there is no need to spend manpower to cut down the spirit wood, which consumes a large amount of spirit charcoal resources, and it is endless.

However, this copper furnace mountain is the property of the Immortal Sect, and it costs money. There are hundreds of alchemy furnaces and refining furnaces in the outermost area, and the temperature of the earth fire is low. Renting a first-order alchemy furnace only costs one spirit stone for one day. ”

Wang Qiudao.

"A piece a day, it's cheap. ”

Su Chen nodded.

In the past, he was alchemy in Chaoge Immortal City, and his daily consumption of spirit charcoal was more than one spirit stone.

On the inside of the crater, there are stone steps that have been carved out, so you can go deeper.

There seems to be a higher-level independent alchemy room and a refining room below. The deeper you go, closer to the ground, the hotter the natural temperature becomes.

"Below, there is a second-order alchemy room and a refining room, which require ten spirit stones to rent for a day. Even better than this, there are third-order alchemy rooms and refining rooms, but as much as a hundred spirit stones are rented for a day, which is not something that everyone can spend. In this Immortal Sect, only the elders of Jindan often use the third-order earth furnace. ”

Wang Qiu said enviously.

Although he was an alchemy master, he was rarely able to raise third-order medicinal materials, and he could only refine them two or three times a year at most. The more elixirs that are refined on weekdays are all refining first- and second-order elixirs to earn spirit stones.

Wang Qiu led Su Chen to the bottom of the crater.

Below, the flames are like the wind.

Su Chen had to release the protective shield to resist the strong flame qi.

After descending hundreds of zhang deep, I only saw the foundation building monks alchemy and refining weapons. The cultivation of the Qi refining period cultivator is below, and he can't stay at all.

"Master Wang!"

On the way down, occasionally one or two alchemists appeared and greeted Wang Qiu.

Wang Qiu just nodded lightly.

He is an alchemy master, and among the alchemists of Penglai Immortal Sect, he has a higher status, second only to the three alchemy masters of the Jindan period.

"Senior Brother Su, there are many first- and second-order alchemy rooms here to choose from. I'll go to the third-order alchemy room first, refine a pair of elixirs, and when it comes out, we'll have another exchange of alchemy!"

Wang Qiu had a third-order medicinal herb and a few second-order spiritual herbs in his hand, and he hadn't touched the alchemy furnace for two months, so he couldn't wait to go to alchemy.

He paid the rent of a hundred spirit stones to a foundation building monk who guarded the Copper Furnace Mountain, rented a third-order alchemy room, and went in for alchemy.

"Good!"

Su Chen said goodbye to Wang Qiu.

After that, he took out five hundred spirit stones and said to the monk guarding the mountain, "Help me with a third-order alchemy room, rent it for five days first! If it is exceeded, I will pay it when I come out." ”

"Third order, five days?"

The foundation building monk guarding the mountain looked at the five hundred spirit stones in Su Chen's hand, his expression was surprised, and he almost wondered if his ears had heard it wrong. But he still took Su Chen and opened an alchemy room.

There are only three third-order alchemy rooms at the bottom of the Copper Furnace Mountain.

Because on weekdays, this third-order alchemy room is actually not often used by monks, and the three rooms are completely sufficient. Even the elders of Jindan rarely use this alchemy room ten times a year.

In one of them, there is a Jindan elder who has been refining the pill in it for many days, and it is estimated that it will take half a month to come out.

And Master Wang Qiu's alchemy occupies a room, which is nothing.

This strange foundation building disciple who had never seen it before directly occupied a room, which made the mountain guard monk quite confused.

--------

PS The whole area was blacked out, and the transformer of a telephone pole was burned, I thought it would be restored immediately after a stop, and the power supply of the laptop was used up, but there was no movement at night, and I wasted most of the day, and vomited blood in depression.

As a last resort, I ran to another place to open a room, and finally coded a chapter.

Keep doing it, and try to write the next chapter in the evening.
