Xuantian Xin's alchemy room was full of ordinary pills, and Mu Li couldn't look at it, so he let the martial saints divide it up.

After that, apart from the elixirs in those gourds, there was nothing precious to be found.

After Mu Li looked around, his eyes fell on the big Dan furnace in the middle of the room, which was more than one person tall.

This is a bronze big Dan furnace, I am afraid that it weighs thousands of catties.

Generally, immortal cultivators have their own small Dan furnaces, which are convenient and practical, and they are easy to carry.

Such a large Dan furnace in front of him is not often used by ordinary alchemists, this kind of big Dan furnace is basically used to refine pills that are not easy to form for a long time, and it requires a good ability to control the heat, and the amount of materials added must also be according to the amount, otherwise it is very dangerous when the furnace is fried.

Of course, Xiang Muli's alchemy technique in the palm of his hand is relatively advanced, and ordinary alchemists can't use it at all.

Mu Li approached the bronze furnace and immediately felt a force of resistance.

There is a formation prohibition to seal the Dan furnace......

It completely sealed the breath inside the Dan furnace and prevented it from leaking, and it also made it impossible for outsiders to touch the inside.

Mu Li's eyes flashed.

If you do this, it means that there is a chance that there is an extraordinary Great Dan in the Dan Furnace, and even has spirituality and will absorb the aura by itself.

Mu Li instantly became interested, and circled around the Great Dan Furnace a few times.

The prohibition on this Dan furnace is more complicated than the one outside the house, and it is obvious that the owner cares more.

Mu Li sensed lightly, and it took a lot of time to analyze the principle of the prohibition.

He smiled, took out the broken sword again, and slashed it towards some places on the outside of the Dan furnace, drawing a mysterious trajectory.

"Poof!"

The surface of the Dan furnace suddenly flashed with light, and then disillusioned.

Mu Li stretched out his palm and slapped it on the Dan furnace.

"Bang!" The lid of the Dan furnace was flown up by him, revealing the world inside.

Mu Li jumped up and stepped on the ears of the Dan furnace to look inside.

At this glance, his eyes froze.

"Life Creation Pill!" He said a few words in surprise.

The pills placed in the Dan room are all very ordinary elixirs, but the ones in this big Dan furnace are different, there is a Creation Pill in it!

The pills are divided into grades, which are spirit level, heaven level, and god level, and each level is divided into upper, middle and lower grades.

Like the ones that Mu Li had refined before, they were basically spirit pills of lower grade spiritual level, and the pills left in the Xuantian Heart Alchemy Room were also of this grade.

However, the dusty living pill in the Great Dan Furnace was different, and it had directly crossed a great realm.

This is a heaven-level Heavenly Pill!

This level of elixir is already considered a relatively precious elixir among middle-level cultivators, and it is even more precious on this earth, and it may not be able to be refined with Mu Li's current cultivation.

Heaven-level Heavenly Pill, not to mention the Yuan Dan Period, even the immortal cultivators of the Divine Soul Stage have to compete for it.

Mu Li didn't expect that there would be such a good pill in the Dan Furnace sealed by Xuantian Heart, and even he was tempted.

It is a milky white elixir, the size of a pigeon's egg, with a smooth and round surface and a faint fragrance.

This level of pill, Mu Li may be able to burst if he takes it now, and it will be of great benefit to take it when he enters the Yuan Dan stage.

A wisp of purple qi emanated from Mu Li's body, rolled up the Creation Pill at the bottom of the furnace, and floated into his hand.

"Huh?" Mu Li frowned suddenly.

"Semi-finished products?"

This Creation Pill is a semi-finished product, and the last step of the Fusion Pill has not been completed.

It can only be regarded as a half-step Tiandan.

The effect is greatly reduced.

"What's going on?" Mu Li's face was puzzled, looking at the roundness of this pill, it didn't look like an alchemy failed, it was obviously only the last step, as if it had come to an abrupt end, causing this pill to lack some necessary things and not become a finished product.

Mu Li couldn't figure it out, if the person who made the alchemy was Xuan Tianxin, why did he pinch off the last step and let a Tiandan that was originally completed become a semi-finished product?

It doesn't make sense......

"No, it's a good Tiandan, how can the effect be greatly reduced because the last step is missing?" Mu Li was unwilling, and put the semi-finished product Creation Pill back into the Dan furnace.

He wants to rerefine the furnace and complete that last step, refining the Creation Pill into a finished product.

It's a semi-finished product that's just one step away, and he believes he has the ability to do it.

Mu Li covered the Dan furnace and released his own purple Dan fire to ignite the fuel at the bottom of the Dan furnace.

With a solemn face, he sat cross-legged next to the Great Dan Furnace, controlling the size of the fire.

When the other people in the Dan room saw his sudden action, their faces were serious, and they all gathered around, not daring to speak, and watching quietly.

As the purple flame churned, the Dan furnace gradually heated up, and the furnace body emitted a cyan glow.

After a while, the fragrance spread out from the lid of the furnace and filled the entire Dan room.

"It smells so good!"

The people next to him all showed a different color, this elixir had a strong fragrance, and when they smelled it, they felt refreshed, and the martial saints felt that their bodies were smooth, and even the cultivation realm was a little active.

"What kind of elixir is inside?" They waited in shock.

As time passed, the Dan incense became more and more intense, and the martial saints hurriedly sat around the Dan furnace under this breath, breathing that breath and cultivating.

This is the Dan Qi when you want to become a Dan, and the effect is extraordinary.

The aura emitted by the heaven-level elixir was several times better than those ordinary elixirs.

They were cultivating, and there were really people who broke through on the spot, and a junior martial saint was promoted to an intermediate martial saint, revealing an extremely excited look.

Others have also benefited greatly, and the realm has been shaken.

They were even more amazed, full of curiosity about the unknown divine pill inside the Dan furnace.

"It's almost Dan." Mu Li's face was dripping with sweat, the blue light on the Dan furnace was even stronger, and the lid of the furnace was already trembling gently.

A breath began to permeate the Xuan Palace.

In the depths of the Xuan Palace, there was an existence that was alarmed by this breath.

"Someone is refining the Creation Pill!" He let out a voice of surprise.

Mu Li's whole body was tense, and the Creation Pill had already reached the last step, the last step that the previous refiner had abruptly stopped.

"Buzz ......"

The lid of the Dan furnace floated up, and a milky white pill flew out of the Dan furnace, suspended above the Dan furnace, and the halo flowed, absorbing the aura of heaven and earth on its own.

When the Creation Pill absorbs enough aura, it will be able to become a pill, and the true heaven-level pill will be born.

"Boom!"

Suddenly, the heavens and the earth above the Xuangong changed color, and there was a roar of thunder and lightning.

Mu Li's face changed, and he was extremely surprised.

How can it be?

Only when the god-level elixir is born will there be a catastrophe and thunder, which is unreasonable.

The Creation Pill is only a heaven-level pill, and it is not much worse than a god-level pill.

"What's going on?" The others looked terrified, because the thunder and lightning in the sky roared directly above the Xuangong Danfang, and they would split down at any time.

The aura of the Creation Pill became stronger and stronger, and the thunder and lightning roaring in the sky became louder and louder.

At this time, the warriors in the Xuan Palace all looked up at the sky in horror, not understanding what had happened to cause such a heavenly change.

As far as the eye can see, the sky outside the Xuan Palace is clear......

"How could a mere Tiandan attract a thunderstorm?" Mu Li's face was gloomy.

Suddenly, an idea popped into him.

Don't......

When Xuantian Xin was refining this Creation Pill, it was for this reason that he gave up the last step that was close at hand?

Mu Li looked at the sky outside the house again, and the breath of thunder and lightning gave him a sense of familiarity that he hadn't seen for a long time.

Suddenly, a picture came to his mind.

He once encountered a foreign race in a Taoist temple on a mountain with Xue Ling'er, and was destroyed by him, and one of the aliens was angry and burst out with amazing strength, only to be destroyed by the thunder.

The breath is exactly the same......

In this piece of heaven and earth, no power beyond the limited level is allowed to appear, otherwise it will attract heavenly punishment......

Mu Li guessed like this, and his face was ugly.

What's going on?

What's really going on Earth?

Wasn't there still the power to move mountains and seas in ancient times?

Those Yuhuang Prefecture Mu Ke are all powerful qi cultivators, and the level of cultivation strength must be much higher than the current level of thunder tribulation?

Why was it possible in antiquity, but now it is restricted?

What does this rule of heaven and earth have to do with the decline of qi practitioners in ancient times?

Mu Li hesitated.

He thought he couldn't stop the thunder from heaven.

This Creation Pill can't be refined, it can only be a semi-finished product.

But he was not reconciled.

"Boom!"

Suddenly, a force erupted in the depths of the Xuan Palace, affecting this side.

The aura around the alchemy room changed, the aura of heaven and earth became chaotic, and the Creation Pill that was about to become a pill was greatly affected, and it fell into the furnace after shaking a few times.

Mu Li's body shook and withdrew his spiritual power.

"Who is it?" He was startled, and subconsciously sensed his surroundings.

There was a dead silence in the Xuan Palace, and there was no breath.

Mu Li didn't let go.

How did that power burst out just now?

Is it a person, or is it the Xuan Palace itself?
