In an empty cultivation room, a three-person alchemy furnace was emitting smoke, and the furnace was open and hanging in the air.

Below it, purple-yellow flames rose, and waves of heat spilled out in all directions.

With Mu Bei's current cultivation, he couldn't use fire-based spells, so he bought a large number of firestones, which could be used only by relying on his own true yuan to ignite them.

This time it was the 'Yuan Yi Dan' in the second-order elixir, which could greatly improve the cultivation progress of the cultivators in the Spirit Movement Period.

The 'Gathering Spirit Pill' issued by the academy every month is a first-order elixir, which only has the effect of accelerating the absorption of spiritual power, and compared with the second-order elixir 'Yuan Yidan', the effect is many times worse.

'Yuan Yidan' can also be purchased online and in the academy, Mu Bei has already bought it, but the quality of the pill under mass production is too poor, and the best quality of it is only able to reach the middle grade, which cannot meet his requirements at all.

"The photo of the pill was taken by them with a beauty camera! I want to return it!"

This is Mubei's complaint when he received the pill online......

Therefore, you still have to do it yourself to have enough food and clothing!

Black blood lotus, Xuanqing liquid, crystal fire grass, thousand-year-old ginseng mustache..... One by one, the medicinal materials were put into the Dan furnace, and then the furnace lid fell and entered the most important refining link.

Mu Beipan sat in front of him, constantly playing tricks into the Dan furnace, the fire was sometimes small, sometimes violent, and there was a gurgling sound from the furnace.

Seventy-two magic tricks were played, the furnace fire was added to the fullest, and the reaction in the alchemy furnace intensified, and bursts of fragrance overflowed.

Traditional alchemy requires the alchemist to concentrate on the entire refining process, and if there is a mistake in one link, not to mention the failure of the refining pill, there will even be the danger of destroying the Dan furnace and injuring oneself!

There were beads of sweat the size of beans sliding down Mu Bei's face, although he knew the knowledge of alchemy well, and he had refined it countless times in his dreams, but he had not practiced it in reality after all.

In this refining, it is still unknown whether it will succeed or not!

Activate the Furnace Cultivation Formation......

The Crystal Fire Grass can only be refined at high temperatures for seven minutes and twenty-three seconds, after which the furnace fire must be kept warm and heated again after five minutes......

More than six hours passed, and the aroma emanating from the Dan furnace became stronger and stronger, making people smell like they were ascending to immortality.

Mu Bei's eyes became more and more solemn, he knew that now was the most critical moment, and it was time to see if he could succeed!

Forty-nine spells were played in a row, and the Dan furnace floated off the ground, rotating rapidly, and all the magic circles in the furnace were activated.

"Not good!"

At the critical moment, Mu Bei felt that his spiritual power was lacking for a while, and it was too late to adjust.

Rumble!

With a loud bang, the floating Dan furnace fell to the ground, the furnace was shaken open, and the pills that were about to take shape were all scrapped and rolled out at this moment.

Mu Bei hurriedly breathed, then got up and went over to check.

There was nothing wrong with the alchemy furnace, he picked up one of the pills, picked it up and sniffed it, there was an unpleasant pungent smell.

"Alas...... All of them are scrapped, and these medicinal materials are worth hundreds of millions of ...... But fortunately, it was only an experiment, and not all the materials were used. ”

Although I feel distressed, I have no choice but to refine it from scratch again at this moment.

"The current cultivation is indeed lower, and the true yuan is not good...... Alas, it seems that we can only buy some more spirit stones!"

The spirit stone is a stone that contains a large amount of spiritual power, and the monks can use it to assist in cultivation, quickly absorb spiritual power, and can also function for various magic weapons, greatly reducing the user's spiritual power supply.

It is generally bred in the blessed land of the cave heaven, and it can also be made by people who have cultivated to the highest level.

It is precisely because of its wide range of uses, precious value, and great effect on cultivation that each sect will reserve a considerable amount of spirit stones.

In modern times, it is the currency used by high-level cultivators to trade, and it is used to replace the Federation Coin, which is already astronomical in payment.

According to the quality, the spirit stone can be divided into low-grade spirit stones, medium-grade spirit stones, high-grade spirit stones and top-grade spirit stones, and their value has also increased exponentially.

Generally speaking, a low-grade spirit stone is equivalent to 10 million federal coins, a medium-grade spirit stone is 100 million federal coins, and a high-grade spirit stone is 1 billion federal coins.

And the best spirit stones are too precious and rare to be measured by money.

Someone had exchanged a top-grade spirit stone for a villa in the center of Tianyu City among the top ten heaven-level cities in the Federation!

Mu Bei was ruthless and directly bought a hundred high-grade spirit stones on Taojing.

Soon, the space not far away was distorted, it was the space channel specially opened by Taojing Company for large single transactions, and a larger demon winged beast fluttered its wings and flew out with its tail wagging its tail, and when it saw Mu Bei, a spirit retracted its big tongue stretched out of its mouth, and flew towards him at an accelerated speed.

After receiving the spirit stones, Mu Bei took all the remaining materials, thought about the first refining, found out which steps could be improved, and then cleaned up the site and prepared to start refining again.

"You can also refine once, if you fail, you can only buy materials again, you must succeed!"

Determined to make up his mind, Mu Bei held a high-grade spirit stone in his hand and put all the rest of the spirit stones back into the space ring.

This refining was very successful, and with the first trial, everything was mastered.

Half a day passed, and with a sound of shaking on the ground, the refining was finally completed, and there was not the slightest mistake in the middle.

Mu Bei opened the alchemy furnace to see how the elixir was refined.

When the furnace opened a corner, a rich fragrance came to his nose, and he only felt a trance, as if he was in a fairyland, and his body and spirit were relaxed to the greatest extent.

Looking into the furnace again, the round and transparent pills with a maroon luster were lying in them, Mu Bei took out one and observed it carefully.

"Danxiang alone has the effect of removing diseases and evils, strengthening the body, the Dan body is transparent, flawless, and fluorescent, it is the best!"

Mu Bei was pleasantly surprised, he didn't expect that he could refine the best 'Yuan Yidan' this time, and in terms of efficacy, it was at least ten times stronger than the one purchased outside, and any one could be sold at a sky-high price!

A whole furnace of the best Yuan Yidan, a total of forty-nine!

"The 'Nine Methods of the Dan King' is really a top-notch alchemy technique, and practicing a superb elixir is like playing, and it is effortless. ”

Putting away the pill, Mu Bei also shook his head and sighed, he used the top alchemy method collected in the Luo Tian Holy Sect's Hidden Scripture Pavilion, but it was also because he himself was in place to refine it.

After putting away the Dan furnace with the space ring and cleaning up the site, Mu Bei took out a pill and ate it without hesitation.

The pill melts in the mouth, and there is no need to chew it at all, like a clear stream flowing all over the limbs.

After a while, there was a feeling of warmth all over my body, and the true yuan in the dantian also began to be driven!

Mu Bei knew that the effect of the medicine had begun to exert itself, and he began to practice the exercises.
