"Ding, the host has completed the task of scattering wealth and building the foundation Dan Fang, and the task will be settled in thirty days!"

In the Little Star Realm, in Gu Changsheng's mind, the voice of the system sounded.

"Huh, didn't I give the Zhuji Dan Danfang to Meng Fuzi a long time ago? Why did the dog system only prompt me now?"

Gu Changsheng was slightly surprised, but soon he was attracted by the one hundred and five stars in the sea of dantian qi, and his eyes were full of extremely excited looks: "No matter, in two days, I have already condensed six star golden pills, as long as I condense three more, I will be able to break through to the middle stage of the golden pill!"

Gu Changsheng was almost in tears, he had stayed in the early stage of Jindan for more than eighty years, and he was about to go crazy.

And now, he finally sees hope.

Gu Changsheng was immersed in the state of cultivation again, and launched an attack towards the middle stage of the Golden Pill!

......

In the middle of a valley at the inner gate, the vegetation is extinct, the rocks are black-brown, and on the mountain wall, there are rows of caves, some of which are still smoking.

This is the Alchemy Hall.

It is said that thousands of years ago, the hall master of the alchemy hall was also the peak master of Tianji Peak, and Tianji Zhenren thought that the construction of the palace was flashy, and directly dug the cave to connect the fire veins in the center of the earth, making it easier to refine the pill.

Therefore, this row of caves has become an alchemy hall.

Li Youde, as an inner disciple of the Alchemy Hall and also an alchemist, naturally has his own exclusive cave.

Li Youde named it the Fire Dragon Cave!

In the Fire Dragon Cave, there are living rooms, cultivation rooms, alchemy rooms, etc.

After Li Youde came back, he took the token to the Alchemy Hall Treasury to receive some elixirs, and then went directly into the alchemy room.

In the center of the alchemy room, there is a huge Bagua Dan furnace, which looks ordinary and mysterious, and there is a formation shrouded below, which can stimulate the fire veins in the center of the earth at any time and be used for alchemy.

This Bagua Dan furnace is the best spiritual weapon, and the success rate of refining the elixir is extremely high, and it is Li Youde's special alchemy furnace.

Li Youde took out all the elixirs he had received from the treasure house.

"Ebony vine, Xuanyang golden sand, flame fruit...... These are all fire-attribute elixirs, Qingxuanmu, Lingguang Grass, and Shengyuan Flower...... These are all wood-attribute elixirs......"

There are hundreds of elixirs of the five elements attributes that Li Youde took out from the treasure house.

He had already determined that the Xingchen Dogtail Grass could replace the Qilin Grass, but it also needed five kinds of elixirs with the Five Elements Attributes to replace the Five Elements Lotus.

The power of the five elements contained in these five elixirs must be the same, and they can restrain each other and achieve the perfect state of the Five Elements Lotus.

Otherwise, even if there is a slight difference, it will be impossible to refine the Immortal Zhuji Dan.

"There are tens of thousands of combinations of these five element attribute elixirs, but according to my research, there are also hundreds of combinations that are most likely to replace the Five Elements Lotus, which means that I need to try hundreds of times!"

Li Youde's eyes were full of fanatical looks, extremely excited.

He faintly felt that the Immortal Zhuji Pill might be an epoch-making elixir, and once it appeared, it would shock the world.

And he, is making and witnessing history!

Closing his eyes slightly, he suppressed the surging thoughts, and his mood gradually became unwavering, and when Li Youde opened his eyes again, he had become extremely calm.

"Enlightenment!"

Li Youde's hands were sealed, and he shouted violently, and immediately urged the formation under the Bagua Dan Furnace.

Suddenly, the bright spiritual light flickered, and there seemed to be a fire dragon spraying in the formation, and the blazing light bloomed, and the raging flames burned, and the Bagua Dan furnace was enveloped in an instant.

The most precious things in Tsukidan are Pure Yang Vine and Taiyin Grass, which can only be found in some secret worlds, because of these two main limitations, the yield of Tsukidan is not high.

Other auxiliary elixirs are quite common.

This time, Li Youde took out a hundred auxiliary elixirs.

The Bagua Dan Furnace trembled slightly, and as Li Youde urged the Earth's Heart Fire Vein, the runes on the Dan Furnace lit up one after another.

When Li Youde was alchemy, his expression became extremely focused.

His Dan Dao attainments were already extremely high, and now although he was using the alchemy method on the Immortal Foundation Building Dan, he didn't even have the slightest rustiness, as if he was flowing with clouds.

This kind of alchemy technique is called the Nine Turns Mixed Yuan Refining!

The Nine Turns Mixed Yuan Refining has extremely high requirements for spiritual power and fire control techniques, requiring that after refining the elixir, it will be divided into nine realms, and the different attributes of the elixir will be used to construct a mysterious mixed element realm.

Within this realm, the six Dan liquids are quenched out of all the impurities, perfect, and finally mixed into one, condensed into Dan!

One by one, the elixir entered the Bagua Dan furnace, was quenched by the flames, and then turned into a pill liquid.

After investing thirty auxiliary elixirs, Li Youde quickly put five Five Elements elixirs and one Star Dogtail Grass into the Dan Furnace.

The star dogtail grass is emerald green in color, fluffy, and looks like a dog's tail, but there is a star brand on it, shining with bright starlight, which looks very mysterious.

The vision of ten thousand stars with the same brilliance made the Wuji Star Palace give birth to this special elixir, absorbing the power of hundreds of millions of stars, and condensing a trace of innate mixed energy.

It's just that the innate mixed yuan qi is too little, and in the past, the Xingchen dogtail grass was used to refine some low-grade spirit pills for the disciples in the qi refining period.

No one thought that Li Youde would actually use it to refine Zhuji Dan!

All the elixirs turned into Dan liquid, and then under Li Youde's control, they were divided into nine realms, and the aura attracted and intertwined with each other, forming a mysterious mixed yuan realm in the Dan furnace!

In that realm, Li Youde actually sensed that the pill liquid had absorbed a large amount of spiritual energy and flame essence, becoming extremely pure, and the medicinal power was stimulated to the extreme.

"Not good!"

Li Youde's face changed suddenly, the nine pill liquids were originally intertwined with each other, but at this moment, they suddenly became chaotic.

The Mixed Yuan Realm collapsed in an instant, and all the Dan liquid was incinerated into ashes by the flames!

This also means that Li Youde's first alchemy failed.

"The power of the fire of the Xuanyang Golden Sand is too strong, suppressing the power of the wood of the Living Grass...... Moreover, the Xingchen Dogtail Grass was put down early, resulting in a trace of the innate mixed element qi that was not strong in the first place, and it did not exert the effect of maintaining balance......"

Li Youde was not disappointed, but summed up the gains and losses and looked for the problem.

He didn't expect to succeed at one time, but he hoped to keep finding out the problem, closing the gap, and finding the most suitable elixir and alchemy method.

In this way, Li Youde began to keep trying.

The Five Elements Lotus contains the power of the Five Elements, and it is the most perfect state, how difficult is it to replace the Five Elements Lotus with the Five Elements Elixir?

But Li Youde has found the right direction, and all that remains is to keep trying.

Once!

Five times!

Ten times!

Thirty times!

......

All failed.

After each failure, Li Youde took the elixir to restore his mana, while summarizing the gains and losses.

In the blink of an eye, nine days and nine nights passed.

Li Youde also failed eighty times.

Although I have failed so many times, it is not for nothing.

More than sixty times before, they had not yet reached the state of condensing pills, and the mixed element realm collapsed, and the pill liquid was completely turned into ashes.

And the last dozen or so times were when they were in Ningdan, and they failed!

Of course, if Ning Dan fails, it is inevitable to fry.

Every time he blew up the furnace, Li Youde was disgraced and looked very embarrassed, and even a high-grade defensive spirit weapon robe he bought was blown to pieces.

But Li Youde did not have any frustration, but his eyes were shining, and he had vaguely touched success on the road of failure.

“...... Ebony vine, chalcedony mushroom, Xuanyu fruit, spiritual light rest, pure yuan golden crystal, the five elements of the five elixirs should be in the most perfect state, and the star dogtail grass also needs five plants, five innate mixed yuan qi, and the fusion of the five elements elixir to be able to condense the true immortal Zhuji Dan!"

Li Youde muttered softly to himself.

Then, he swallowed a Yunshen Pill, lay down directly, and began to fall asleep.

Nine days and nine nights of sleepless attempts at alchemy, although there is a spirit pill to restore mana and spirit, Li Youde's state is also exhausted to the extreme.

He vaguely felt that maybe he would be able to refine the true Immortal Tsukidan next time, so he lay down and rested without hesitation.

When the spirit and spirit returned to their peak state, it was the moment when he once again refined the Immortal Zhuji Dan!

......

"What's going on? Senior Brother Li's Fire Dragon Cave, the sound of the furnace has sounded more than a dozen times in the past two days, what kind of elixir is he refining?"

Many of the disciples of the Alchemy Hall had curious looks in their eyes.

"I don't know! It stands to reason that Senior Brother Li's Dan Dao attainments are extremely strong, and Senior Brother Su Li has praised him quite a lot, calling him a Dan idiot! The hall master even gave him most of the tasks of refining Zhuji Dan, he shouldn't be able to fry the furnace!"

"That's right! Even if Senior Brother Li refines a new elixir, he will succeed if he fails once or twice at most! This more than a dozen times in a row is not a succession of senior brother Li refining the treasure pill?"

"The Fire Dragon Cave has a ban set by Senior Brother Li, and we can't enter it, I hope Senior Brother Li is okay!"

Everyone was very worried.

Li Youde is a good man and treats many juniors and disciples very well, so everyone cares about him very much.

As a result, after more than a dozen times of frying, for three days, the Fire Dragon Cave was very quiet, and Li Youde did not come out.

"Senior Brother Li can't have any problems, right? No, could it be that he has gone mad in alchemy? Hurry up and report to the elders!"

Some people's eyes were full of worry, and they couldn't hold back any longer, and they went to report to the elders of the Alchemy Hall one after another.

Fire Dragon Cave.

Li Youde, who had slept for three days and three nights, woke up, and he was unaware of what was going on outside.

His spirit and spirit had reached the peak, and his eyes were full of extremely expectant looks, ready to start refining the Immortal Zhuji Dan!
