Since the remaining points are not enough to buy space stones (high-quality), Li Yuan plans to put the space mustard technique aside for the time being, and it just so happens that he has just obtained the teleportation skill and still needs to practice.

There are still 159,070 points left, and Li Yuan has exchanged 100 years of spiritual power at one time.

A large cloud of golden liquid instantly appeared around Li Yuan, enveloping him.

'Gollum'

Without the slightest preparation, Li Yuan spat bubbles in the liquid formed by spiritual power.

In the past, it was all spiritual power in a fog state, but due to the excessive amount of Li Yuan's one-time exchange this time, it actually appeared directly in the form of liquid.

It took Li Yuan three hours to absorb the spiritual power this time, and after all the spiritual power was absorbed, the true qi in Li Yuan's body was agitated, and the little Li Yuan who was located in the dantian opened his small mouth and swallowed it for a while, absorbing all the spiritual power that entered the body into his abdomen.

Li Yuan noticed that the figure of little Li Yuan in the dantian was a little more condensed.

Look at the cultivation again, the middle of the Yuan infant?

It can't be dazzling, right?

Li Yuan rubbed his eyes and looked at Xiu Wei again, it was really the middle of the Yuan Infant!

A hundred years of spiritual power has only been upgraded from the early stage of the Yuan Infant to the middle stage?

You must know that the spiritual power consumed by Li Yuan in the entire Jindan period is not a hundred years, and it is really difficult to upgrade in this Yuan Infant Period.

The remaining spiritual power, Li Yuan does not plan to use it to buy spiritual power.

He started from getting the alchemy, first because the materials were not enough, and then he had to receive guests, and he had no time to practice, taking advantage of the fact that he had obtained three days to close the shop after completing the Fahai transaction this time, Li Yuan planned to refine the Dali Dan.

Once again, an alchemy room was opened in the backyard, next to the bedroom that Li Yuan had only used twice so far.

The Dan furnace for alchemy needs to be exchanged by Li Yuan himself in the shop.

There are dozens of Dan furnaces in one slip, the cheapest one costs 50,000 points, and the most expensive Li Yuan can only see it???? Probably because the grade of the Dan furnace is too high, it has exceeded Li Yuan's authority, and it cannot be viewed.

Take a look at the 50,000 alchemy furnace, and then look at your remaining 59,070 points.

Li Yuan scolded secretly, "What's special, every time the master needs something, it's the same as if he had calculated it in advance, and fortunately, he left a little bit for the master to save his life."

Scolding in his mouth, but without hesitation in his hand, Li Yuan exchanged the alchemy furnace for a profit.

Although it is the cheapest alchemy furnace in the store, it also has a very loud name 'Fire Dragon Ding'.

As the saying goes, you get what you pay for, and at such a cheap price, this alchemy furnace naturally doesn't have any additional bonuses, it's really just an ordinary Dan furnace that can't be ordinary anymore.

It's just that the materials used to refine this Fire Dragon Ding are all in the cultivation realm, and compared with the alchemy furnace in the mortal world, it is still a lot stronger in terms of hardness, at least there is no need to worry about the instant explosion furnace.

Take out the materials for refining Dalidan, put a pile of rhinoceros horn, a pile of Fang Lingcao, and a pile of dragon sweet fruit.

There are a lot of materials sent by Meng Po, enough for Li Yuan to refine hundreds of times.

First of all, he took a 210-year-old rhinoceros horn and put it into the fire dragon tripod, Li Yuan put his hands on the fire dragon tripod, and carefully recalled the extraction method of the rhinoceros horn.

After a while, Li Yuan communicated the true qi around his body, and slowly entered the Fire Dragon Ding with his hands.

There was a soft 'boom', and a red flame appeared out of thin air in the Fire Dragon Ding, wrapping the rhinoceros horn that Li Yuan had thrown into it before.

Li Yuan worked hard to regulate the temperature of the flames in the Fire Dragon Ding according to the way he remembered.

The rhinoceros horn inside the "poof" tripod was directly burned into a pile of ashes by the flames.

It turned out that it was the first time Li Yuan used the alchemy furnace, and the heat was not in place, and the temperature was high, so he directly burned the rhinoceros horn.

Retracting his hands that were attached to the Fire Dragon Ding, Li Yuan waved his sleeves lightly to remove the ashes in the Fire Dragon Ding.

Taking a rhinoceros horn again, Li Yuan carefully recalled the refining process just now before throwing it into the Fire Dragon Ding again.

Just now he made a mistake in the middle and late stages of forging, and Li Yuanfang still maintained his previous firepower and did not suppress the flame temperature, causing the rhinoceros horn to burn when it was about to be successfully extracted.

During this refining, Li Yuan's eyes stared at the Dan furnace for a moment, waiting for the rhinoceros horn to be successfully refined, and quickly suppressed the flame and lowered the temperature.

"Poof" was another soft sound, and this time the rhinoceros horn that was about to be successfully refined turned into a puff of green smoke, and there was not even any scum left.

This time, it was because Li Yuan lowered the temperature of the flame too low and too fast, and the temperature went from extremely high to very low, causing the rhinoceros horn to evaporate directly.

Took a rhinoceros horn again, this time Li Yuan did not hesitate, and threw it directly into the Fire Dragon Ding, after two failures, this time, he had already calculated the control degree of the flame in his heart in advance.

Sure enough, this time, in a quarter of an hour, Li Yuan extracted the essence of rhinoceros horn, and the extracted rhinoceros horn essence was in powder form.

After succeeding once, Li Yuan extracted the powder of rhinoceros horn one after another, and after extracting twenty copies, Li Yuan stopped moving.

After that, Li Yuan only failed once in rhinoceros horn refining, and the success rate was very high.

The next thing is to refine Fang Ling Cao, the extraction method of Fang Ling Cao is similar to that of rhinoceros horn, with previous experience, Li Yuan extracted twenty parts of Fang Ling Cao powder in a row after failing once.

Putting rhinoceros horn powder and Fang Lingcao powder in wooden boxes and stacking them on one side, Li Yuan began to extract the most difficult dragon fruit.

The extraction method of dragon fruit is somewhat special, it cannot be calcined directly with flames, it needs to be used to form a barrier with true qi, and bake with flames through this barrier.

Among them, the biggest test for Li Yuan is that he needs to wrap the dragon fruit with a barrier of true qi, the true qi barrier cannot be too thick, too thick the flame baking takes more time, it is a great test of endurance, and it cannot be too thin, too thin the dragon fruit will be vaporized instantly.

It took Li Yuan half an hour just to build this barrier, and when the barrier was finally built, Li Yuan was already sweating profusely.

Carefully maintaining the barrier, Li Yuan continued to convey the true qi needed to maintain the barrier with one hand, and pressed it on the Fire Dragon Ding with the other hand, the true qi was input, and the flames in the Fire Dragon Ding rose.

The cyan dragon fruit gradually turned dark red under the roasting of the flame, and the skin gradually wrinkled.

When the first drop of juice dropped, Li Yuan's hand shook, and the true qi barrier broke a small hole, and the flames rising in the Fire Dragon Ding instantly burned the dragon fruit.

"Alas..."sighed, Li Yuan resigned himself to throwing a dragon fruit into the fire dragon tripod again, the true qi barrier was formed, and the flame was baked again, this time, Li Yuan played twelve points of energy, after half an hour of continuous baking, the dragon sweet fruit in the fire dragon tripod dripped the last drop of juice, and the peel was discharged from the true qi barrier, and then swallowed by the flames.

The remaining dragon essence floating in the true qi barrier still needs to be roasted to eliminate impurities.

Another half an hour passed, and after Li Yuan watched that the juice of the dragon sweet fruit did not float out of the green smoke that had been baked, he slowly withdrew the true qi that had been imported into the Fire Dragon Ding.

With a wave of his hand, the juice of the dragon fruit flew out, and it was a brown paste, which was still in a wooden box and set aside.

Li Yuan touched the sweat on his forehead, the juice of this dragon fruit was too difficult to extract.

Li Yuan knew that he still had to optimize the True Qi barrier again, although the True Qi barrier he had just built didn't have to worry about holes, the thickness was still too thick, causing the time it took to bake to soar.

He decided to slowly adjust the thickness of the True Qi Barrier, and then, Li Yuan failed a total of 4 times, this was not a mistake, but Li Yuan did it deliberately, and he relied on each fine-tuning to confirm the thickness of the True Qi Barrier.

When extracting the dragon sweet fruit juice for the fifth time, Li Yuan finally constructed a perfect true qi barrier, and this time, he only took half an hour to refine a dragon sweet fruit juice.

Repeat the extraction again until there are twenty parts of the juice of the dragon sweet fruit, and Li Yuan stopped the movement in his hand.

Seeing that only a small part of the materials had been used, Li Yuanyi waved his hand and received the rhinoceros horn, Fang Ling grass, and dragon carpa into the space mustard seeds.

Looking at the dozens of wooden boxes piled up in his hand, Li Yuan exhaled, and instead of directly starting to refine the Great Pill, he closed his eyes cross-legged and began to operate the Xuanyin Heaven and Earth Gong.

He wants to restore his true qi to its peak, when he extracted medicinal materials before, he consumed most of his true qi, and refining the Great Pill in this state may be a great failure.

Another hour passed, and Li Yuan slowly opened his eyes, and his purple pupils flickered.

With a wave of his hand, the juice of rhinoceros horn powder, Fang Ling grass powder, and dragon sweet fruit was thrown into the fire dragon ding.

His hands were attached to the Fire Dragon Ding, slowly conveying the true qi, the flames in the Fire Dragon Ding skyrocketed, and the temperature was much higher than when he extracted the essence of medicinal herbs before, and Li Yuan's hands on the Ding were faintly hot.

When the extremely high temperature lasted for about ten minutes, Li Yuan's eyes narrowed, and the temperature of the flame in the Fire Dragon Ding instantly decreased, and the three-flavor medicinal herbs that had previously shown signs of fusion due to the high temperature calcination continued to be calcined at an extremely low temperature.

After another ten minutes passed like this, Li Yuan once again raised the temperature in the Fire Dragon Ding to the previous high temperature.

After calcining at such a high temperature and low temperature three times, the three flavor medicinal materials had already fused together, and at this time, this brown semi-fluid was floating in the middle of the Fire Dragon Ding.

After the medicinal materials were fused, Li Yuan adjusted the temperature again, keeping the temperature of the flame at a level that was neither high nor low, and continued to calcinate for about a quarter of an hour.

The original brown semi-fluid gradually turned into a round solid, dripping and rotating in the fire dragon ding.

Retracted his hands that had entered the true qi, waved his hand and took out the pill, and a stream of medicinal fragrance came from the surface.

Looking at the pill in his hand, a light curtain that only Li Yuan could see was generated on the pill.

'Pill, normal quality, can increase the strength of 2,000 catties after taking it, up to three pills. ’

Hey, it's done!

Li Yuan hehehe, looking at the first pill that was refined, he played with it for a long time before reluctantly putting it into the wooden box and storing it in the space mustard seeds.

The first refining was successful, and Li Yuan's confidence increased greatly, striking while the iron was hot, and refining the remaining 19 medicinal materials together.

After refining the twenty medicinal herbs, Li Yuan obtained 19 pills, one of which failed, which was caused by the failure of his true qi during the final baking.

Perhaps Li Yuan was really talented in refining pills, and out of these 19 pills, there were two perfect quality pills.

'Dalidan, perfect quality, can increase 3,000 catties of strength after taking it, up to three pills. ’

As soon as the perfect quality pill was successfully refined, Li Yuan took one between his fingers and threw it into his mouth.

After a while, it melted in the mouth, and it didn't taste anything.

Take a look at the combat power, 5871 points, which is enough to increase the combat power by 200 points, and if you eat three, you can increase it by 600 points, which can catch up with Li Yuan's combat power improved by a small realm.

It's a pity that he can only eat three, and when Li Yuan sighed in his heart, he easily threw another perfect-grade Mighty Pill into his mouth.

He can eat another one, and he plans to wait until he practices the perfect-level Mighty Pill next time.

As for these ordinary-grade Mighty Pills, Li Yuan sold them when he planned to go shopping in the Yin and Yang Realm, and also learned about the purchasing power here.
