Su Chen rented a third-level alchemy room, pushed open a thick stone door, and walked into the stone room.

There is a wire rope mechanism inside the room that can lock the stone door to avoid being disturbed by the outside world.

This alchemy room is dozens of feet in size, with a wall of shiny black rocks as thick as a foot. I don’t know what material it is made of, which isolates the outside flames and heat, and the room is obviously deserted.

In the middle of the stone chamber, there is a third-level alchemy furnace with exquisite carvings, about one foot in size. There is a pipe that can be closed and opened under the furnace, connecting the underground slurry of Tonglushan, and whirring golden flames continue to gush out.

Using earth fire as the fire source, alchemists do not need to add spiritual charcoal at all times. They only need to control the valves of the pipeline to control the firepower, saving a lot of energy.

Su Chen did not immediately refine the extremely difficult foundation-building pill.

Since he last refined the low-level marrow cleaning pill, he has not refined the pill for a long time and is quite unfamiliar with his hands.

He took out a second-level spirit-gathering pill recipe and fifty small portions of prepared spiritual medicinal materials from the Sumeru Ring, and each portion could produce a spirit-gathering pill.

I plan to be familiar with the alchemy that has not been used for a long time, and also get used to the power of this third-level alchemy furnace and earth fire.

The third-level alchemy furnace and earth fire are used to refine the second-level spiritual pills. The speed of forming pills is extremely fast. In about half an hour, a furnace of elixirs can be refined.

Except for resting and meditating for two hours every day, you can refine elixirs twenty times without stopping during the rest of the day.

Stop and think about alchemy in the middle, it should be a little slower.

At the beginning, the dozen or so furnaces were either too hot and the medicinal materials were burnt. Or they were too early to open the furnace and had not yet condensed the pills, and almost all of them were useless pills. But after refining them.

In just two days, Su Chen was obviously happy to feel that his alchemy was improving rapidly.

The first ten furnaces were destroyed, and the elixir rate in the middle twenty or thirty furnaces continued to increase from 10% to 20%. The last ten spiritual gathering pills were almost completed in one go, with a elixir rate of up to 50%.

After refining these fifty small portions of spiritual medicinal herbs, Su Chen obtained fifteen spiritual gathering pills. If the market price is used to calculate the price of spiritual medicinal herbs and spiritual gathering pills, he will lose a lot of spiritual stones in the past two days.

But this is not Su Chen's purpose. He just uses these fifty small spiritual gathering pills to practice the feel and be familiar with the power of the third-level alchemy furnace and earth fire.

Su Chen has returned to his peak alchemy state and then began to refine the foundation-building pill.

Su Chen was not sure of refining it in one go, and cut this set of foundation-building pills into the lowest ten parts, and refining it in ten times.

Su Chen repeatedly read the formula and alchemy method of foundation-building pills more than ten times, keeping it in mind.

The main medicine is a thousand-year-old spiritual medicine "Jadecidalis". This main medicine contains extremely high vital energy, which can completely stimulate the soul power of the ninth level of the Qi Refining Stage, and make the primordial spirit of the Qi Refining Stage produce qualitative changes, and enter the foundation-building realm in one fell swoop.

Five five hundred-year-old "Tianling Fruit, Ice and Snow Lotus, and Snake Flower Defecation" are auxiliary medicines, and their attributes and effects are different.

The Tianling Fruit protects the Tianling Cover of the brain and skull to avoid the powerful impact of the vital energy. The ice and snow lotus guards the body and mind to prevent evil spirits from invading. The snake sheds the flowers and seals the acupoints of the monk's skin to prevent the vital energy from leaking out.

There are 20 other 200-year-old spiritual herbs, "blood crystal grass, earth fire lotus" as adjuvant medicines, each with different functions.

The alchemist’s understanding of the medicinal properties of each spiritual medicinal material is very important. Because their medicinal properties are mutually restrained by solid, liquid, gel, powder and other different states, which will have a huge impact on the alchemy process.

This recipe can produce a furnace of foundation-building pills, totaling ten pieces.

The method to refine this elixir: first put in the five auxiliary medicinal materials such as Tianling Fruit, Ice and Snow Lotus, Snake Shed Flowers, etc., and burn the elixir furnace with Samadhi True Fire for half an hour to melt it into the medicinal liquid. After smelling the fragrance of the medicine, then put it in

"First put the auxiliary medicine into the furnace liquid and smell the fragrance of the medicine."

Su Chen carefully put the first spiritual medicinal material of the foundation-building pill into the furnace one by one, and carefully observed the status of the medicinal liquid in the alchemy furnace with his spiritual thoughts.

Tonglu Mountain.

A flying sword rainbow light fell on the mountain "whizz", showing the figure of a middle-aged alchemist in the foundation-building stage.

"Disciple, I have met Master Zhang Zhuo!"

When many alchemy apprentice and alchemists in Tonglu Mountain saw him appear, they couldn't help but salute him respectfully.

Zhang Zhuo nodded lightly, not caring about it.

He has been an alchemist for more than twenty years, and among the dozens of alchemists in the foundation-building stage realm of Penglai Immortal Sect, he is also a senior and beautiful person.

But he was no longer satisfied with the status of an alchemist and wanted to enter the realm of an alchemist. This was the realm he had always dreamed of.

A few months ago, he spent a lot of effort and finally collected a pair of medicinal materials for the third-level Xuanbing Pill.

This Xuanbing Pill is a third-level spiritual medicine, specially designed for Jindan monks to take. It has excellent effects in suppressing gods and removing demons, and can prevent you from getting into a devil when practicing and breaking through the realm.

Once the Xuanbing Pill is successfully refined, as long as the elixir yield is sufficient to ensure the capital is guaranteed and there is no loss of money. Then he will be successfully promoted to the fourth alchemy master in Penglai Immortal Sect and can do business with the Jindan cultivator.

At that time, even the Jindan elders of our sect would come to him to purchase Xuanbing Pills.

His status in the Penglai Immortal Sect will undoubtedly rise significantly, surpassing the alchemist and becoming one of the only four alchemist masters in the Immortal Sect.

He has prepared carefully for this day for a full year.

"Junior Brother Wu, help me open a third-level alchemy room!"

Zhang Zhuo's face was filled with a faint confidence and a calm smile. He climbed down the steps and came to the depths of the crater, in front of the third-level alchemy room.

The monk surnamed Wu who was in charge of guarding Tonglu Mountain was stunned and quickly bowed and apologized: "Senior Brother Zhang, it's gone!"

"It's gone? Are there three rooms? Why are they gone!"

Zhang Zhuo couldn't help but be surprised.

He remembered that this third-level alchemy room was very free on weekdays.

Penglai Immortal Sect only has four golden elixir masters and three alchemy masters.

Once the alchemy master takes up his position, he often comes out for ten or half a month. But the alchemy masters are fast in and out, and just one or two days is enough. After all, the cost of a hundred spirit stones per day is to burn spirit stones, and not everyone can afford it.

Except for the occasional use of them, who would rent a third-level alchemy room? Three third-level alchemy rooms are rented together, which is too rare.

"Elder Shi Tianlei Jindan has occupied one, and he has been practicing it for more than ten days. Wang Qiu's alchemy master just came and occupied one, and paid the rent for one day, and it is probably coming out soon. There is another one, I don't know who he is, it seems to be a new alchemist, but he has paid the rent for five days, and I'm afraid he will come out in a short while."

Guard Wu hurriedly said.

Zhang Zhuo was stunned and frowned deeply.

A strange newcomer alchemist?

Who will it be?

Humph, he doesn't recognize the alchemist who is a little skilled in Penglai Immortal Sect! This person is probably pretending to be a pretentious person and deliberately attracts attention, so he really wants to spend this big spiritual stone.

He could only wait and wait outside.

Wang Qiu, the alchemy master, has been refining a third-level spiritual pill for most of the day. He should be coming out soon.

He practiced alchemy almost at the same time, and he had never dealt with it decades ago, and no one was better than anyone else. In recent years, Wang Qiu has relied on his first step to become an alchemy master, looking arrogant in front of him.
