Su Chen rented a third-order alchemy room, pushed open a heavy stone door, and stepped into the stone room.

There is a wire mechanism in the room, which can lock the stone door to avoid interference from the outside world.

This alchemy room is dozens of zhang in size, and the walls are feet thick of black and bright rock, and I don't know what kind of material it is made of, isolating the flames and heat from the outside, and the interior is obviously more deserted.

In the middle of the stone room, there was a beautifully carved third-order alchemy furnace, about a foot in size. There is a pipe under the furnace that can be closed and opened, connecting the molten slurry under the copper furnace mountain, and the whirring golden flame is constantly gushing out.

Using the earth fire as the fire source, the alchemist does not need to add spirit charcoal all the time, but only needs to control the valve of the pipe to control the amount of fire, saving a lot of energy.

Su Chen did not immediately go to refine the extremely difficult Zhuji Dan.

Since the last time he refined the low-level marrow cleansing pill, he hadn't refined the pill for a long time, and his hands were quite rusty.

From the Sumeru Ring, he took out a second-order Gathering Spirit Pill pill and fifty small portions of prepared elixir materials, each small portion could produce a Gathering Spirit Pill.

I am going to use it to familiarize myself with the alchemy technique that I haven't used for a long time, and by the way, I will get used to the power of this third-order alchemy furnace and earth fire.

Using the third-order alchemy furnace and earth fire to refine the second-order elixir, the speed of becoming a pill is extremely fast, and it only takes about half an hour to refine a furnace of elixir.

In addition to resting and meditating for two hours a day, the rest of the time does not stop alchemy, which can be refined twenty times.

In the middle, stop to ponder alchemy, and it is a little slower.

At the beginning of the dozen furnaces, either the heat was too fierce and the spiritual herbs were scorched. Either the furnace was opened too early, and the Dan has not yet been condensed, and almost all of them are waste Dan. But to the back.

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

The first ten furnaces were destroyed, and the middle twenty or thirty furnaces continued to increase from one or two percent, and the last ten Gathering Spirit Pills were almost all in one go, as high as fifty percent of the pill rate.

After refining these fifty small portions of spiritual medicine, Su Chen obtained fifteen pills of Gathering Spirit Pill. If the price of the spirit medicine and the spirit pill is calculated by the market price, he will lose a lot of spirit stones in the past two days.

But this is not Su Chen's purpose, just to use these fifty small copies of the Gathering Spirit Pill to practice his hand and familiarize himself with the power of the third-order alchemy furnace and earth fire.

Su Chen had already recovered to the peak alchemy state, and only then did he begin to refine the Zhuji Dan.

Su Chen was not sure that it would be refined at one time, so he cut this pair of Zhuji Danling medicinal materials into the lowest ten small parts equally, and refined them ten times.

Su Chen repeatedly read the formula of Zhuji Dan and the method of alchemy more than ten times, and kept it in mind.

The main medicine, a thousand-year-old elixir 'chalcedony mushroom'. This main medicine contains extremely high vitality, which can completely stimulate the power of the divine soul of the ninth-layer cultivators in the Qi refining period, causing a qualitative change in the primordial spirit of the Qi refining period, and stepping into the foundation building realm in one fell swoop.

Five 500-year-old 'Heavenly Spirit Fruit, Ice and Snow Lotus, Snake Flowering...' are auxiliary medicines, and their properties and functions are different.

Heavenly Spirit Fruit, protect the skull Heavenly Spirit Cover, so as not to suffer from the powerful impact of the vitality. Ice and snow lotus, guarding the body and mind from the invasion of evil spirits. The snake molts and closes the holes in the monk's skin to prevent the vitality from leaking out.

A total of 20 other 200-year-old spirit grasses 'Blood Crystal Grass, Earth Fire Lotus...' are adjuvants, each with different effects.

The alchemist's understanding of the medicinal properties of each elixir is very important. Because their medicinal properties restrain each other, different states such as solid, liquid, gel, and powder will have a huge impact on the alchemy process.

This side, you can produce a furnace to build the base Dan, a total of ten.

The method of refining this Dan: first put in the five flavor auxiliary medicinal materials such as the Heavenly Spirit Fruit, Ice and Snow Lotus, and Snake Molt Flower in turn, and burn the Dan furnace with Samadhi True Fire for half an hour to melt it into a medicinal liquid. Smell the medicine, and then put it in....

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

Su Chen carefully put the first elixir of Zhuji Dan into the furnace in turn, and carefully observed the state of the medicinal liquid in the alchemy furnace with his divine thoughts.

...

Copper Furnace Mountain.

A flying sword rainbow fell on the mountain peak, showing the figure of a middle-aged alchemist in the foundation building period.

"Disciple, I've seen Uncle Zhang Zhuo!"

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

Zhang Zhuo nodded lightly, disapproving.

He has been an alchemist for more than twenty years, and among the dozens of foundation building stage alchemists in Penglai Immortal Sect, he can be regarded as a senior and beautiful person.

But he has long been dissatisfied with the status of an alchemist, and wants to set foot in the realm of an alchemy master, which is the realm he dreams of.

In the past few months, he had spent a lot of effort and finally gathered a pair of third-order Xuanbing Pill medicinal materials.

This Xuanbing Pill is a third-order elixir, which is specially used by Jindan monks. It has an excellent effect of calming the gods and dispelling demons, which can prevent people from going mad when cultivating and breaking through the realm.

Once the Xuanbing Pill is successfully refined, as long as the pill rate is enough to protect the capital, there will be no loss of money. Then he will be successfully promoted to the fourth alchemy master of Penglai Immortal Sect, and he can do business with Jindan monks.

At that time, even the Jindan elders of the sect would take the initiative to come to him and purchase Xuanbing Pill.

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

He has been preparing for this day for a full year.

"Senior Brother Wu, help me open a third-order alchemy room!"

With a faint confidence on his face and a calm smile, Zhang Zhuo walked down the stairs and came to the depths of the crater, in front of the third-order alchemy room.

The monk surnamed Wu, who was in charge of guarding the Copper Furnace Mountain, was stunned for a moment, and hurriedly bowed his hand and said apologetically: "Senior Brother Zhang, it's gone!"

"Isn't there three?

Zhang Zhuo couldn't help but be surprised.

He remembered that this third-order alchemy room was very idle on weekdays.

Penglai Immortal Sect is only four Jindan alchemy masters and three alchemy masters.

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

Except for a few of them who occasionally use it, who would rent a third-order alchemy room? Three third-order alchemy rooms are rented together, which is too rare.

"Elder Shi Tian Lei Jindan occupies a room, and he has been refining for more than ten days. Master Wang Qiu Alchemy just came, occupied a room, paid a day's rent, and is estimated to come out soon. There is another one, I don't know who he is, it seems to be a new alchemist, but he paid five days' rent, and I am afraid that he will not come out for a while. ”

Guard Wu hurriedly said.

Zhang Zhuo was stunned and furrowed his brows deeply.

Strange newcomer alchemist?

Who will it be?

Hmph, in the Penglai Immortal Sect, the alchemist who has a little ability, he doesn't recognize it! I'm afraid that this person is just pretending to be and deliberately attracting attention, and he is really willing to spend this large amount of spirit stone.

He could only endure and wait outside.

Wang Qiu, the alchemy master, has been refining a third-order elixir for most of the day, and it is estimated that he is refining a third-order elixir, so he should come out soon.

He and Wang Qiu were almost practicing alchemy at the same time, and they had never dealt with each other decades ago, and no one was better than the other. In recent years, Wang Qiu has relied on himself to become an alchemy master, and he looks arrogant in front of him.

When he also becomes an alchemy master, let's see what else Wang Qiu has to be arrogant.
