When he got home, it was almost night, and Chu Yuan was very surprised when he saw Yang Wei next to him kneeling cross-legged in the dug stone cave.

Li Qiuyu asked him to open a cave, but he really just opened a hole, which is enough to shelter from the wind and rain, where is this cave?

Seeing Chu Yuan coming back, Yang Wei immediately got up, saluted Chu Yuan, and said, "Welcome Brother Chu home?" ”

Chu Yuan waved his hand and said, "This is your cave mansion?" He pointed to Yang Wei's location.

Yang Wei nodded and said, "I'm used to sleeping in the open air, and I like to suck the essence of the sun and the moon under the shroud of the moon. ”

When Chu Yuan heard this, he was relieved, these monks don't need to sleep, wherever they go, meditate cross-legged, and it is normal for them not to get up for ten days and half a month.

"Oh, that's it, then you can go ahead." Chu Yuan said.

Yang Wei bowed, then sat down cross-legged and cultivated on his own.

Although cultivation is sealed, it doesn't mean that you can't cultivate.

Chu Yuan just walked into the cave with one foot, and the next moment, only a voice came, Chu Yuan turned his head to look, only to see Chen Changqing running quickly, arrived in front of Chu Yuan, and said, "The head asked me to hand over this thing to you." As he spoke, he took out a storage bag from his arms, and there was a paper talisman attached to it, which was a protective charm set up to prevent others from peeking at the contents of the storage bag.

Obviously, Su Changmin didn't want Chen Changqing to see the contents of the storage bag, so he cast a spell.

If Chen Changqing dared to use his divine sense to check the contents of the storage bag, Su Changmin would know.

Chen Changqing knew that there was a lot to do with it, so he didn't dare to look at it, and he was even more curious about Chu Yuan.

I don't know what the head of the house gave Chu Yuan? It's so mysterious.

Chu Yuan took the storage bag, thanked Chen Changqing, and then entered the cave without looking back.

Chen Changqing was stunned, and saw a mortal sitting cross-legged in a narrow stone cave not far away.

The mortal dressed as a farmer, found himself, smiled at himself, and said, "My master is afraid that he is tired, and he has not entertained the immortal master well, so let the old slave entertain you for the master." ”

As he spoke, he stood up, walked out of the stone cave, and then walked to a stone table that he had just built today, and as soon as he exerted his hands, the stone table was easily picked up by him, and put it in a corner of the lawn, and he moved a few stone stools and put them under the table, and said, "Immortal Master, please sit down, I will make tea for Immortal Master." ”

Chen Changqing was only surprised, a mortal, an ordinary farmer, could easily hold a stone table weighing hundreds of catties, Rao is his cultivation during the foundation building period, and he felt a little embarrassed without using spiritual power, but this farmer was obviously a mortal?

I only felt that the people around Chu Yuan were so strange, and there was one who seemed to be in the cave all the time and only showed up occasionally.

It was still a female cultivator in the Qi cultivation period, but when I saw it yesterday, there was no spiritual power fluctuation on that female cultivator's body, which was really strange, very strange.

Anyway, Chu Yuan gave Chen Changqing the feeling that he was getting more and more incomprehensible.

Chen Changqing waved his hand and said, "No need, I have to go back to the mountain to recover my life, thank you for your hospitality." ”

After saying that, he turned and walked away without looking back.

Chu Yuan took the storage bag given by Su Changmin, tore off the charm, and his divine sense entered the storage bag to check, only to see piles of elixirs, I don't know how many piles they were divided into, most of them were elixirs used to refine the Divine Infant Pill, and some were used to refine the elixir of Zhuji Dan and Zhuyuan Dan.

Chu Yuan nodded slightly, and said in his heart that these elixirs are enough for me to use for a while, once this cultivation reaches the foundation building period, the spiritual power required is not comparable to the Qi training period, and the resources required are more than a hundred times that of the Qi training period, not to mention that he is the Five Elements Spirit Root, so on this basis, it will be increased by five times.

Li Qiuyu looked at Chu Yuan and said, "There are so many elixirs, Brother Chu, are you going to refine the pill?" But there is no alchemy furnace here......"

"The alchemy furnaces in this world are too exaggerated, and the purification efficiency is far from meeting my requirements, even if I can practice the heaven-level alchemy, but for a person like me who pursues perfection, there is no best, only better."

Chu Yuan thought to himself: "I'm a man who wants to practice an immortal-level elixir, or even a god-level elixir. ”

"But how can you refine without an alchemy furnace?" Li Qiuyu asked.

"As long as I know the principle of the alchemy furnace and make a more advanced equipment instead, then I will be more trouble-free."

"I told you you don't understand, wait for me to sleep first!" Chu Yuan walked to the side of the bed and lay down, Li Qiuyu walked to the side and began to massage skillfully.

Not long after, Chu Yuanbian fell asleep.

……

The next day, early in the morning.

Chu Yuan got up as soon as he got up, and after washing up under Li Qiuyu's service, he went out and began to collect materials in the mountains.

"Quartz sand, soda ash, limestone, feldspar, etc. are needed to make glass test tubes..."Chu Yuan muttered, looking everywhere for traces of these materials, fortunately, these are common things, and they are not difficult to find, and a large bag was soon collected.

Returning home with these materials, Li Qiuyu asked curiously, "Brother Chu, what is the use of bringing these soils back?" ”

Chu Yuan smiled slightly and said, "Don't look at these things as ordinary, but if they are used properly, they have a wonderful use." ”

When Li Qiuyu heard this, he suddenly became a little incredulous, but Brother Chu was not an ordinary person, but he also believed it a little.

"I still need your help later, just watch and listen to my orders."

Li Qiuyu replied "yes" on the side, and then guarded the side and said no more.

Chu Yuan put the ingredients he brought back in a basin and said to Li Qiuyu, "I want you to crush these materials into powder, keep them dry, and then calcinate them with Danhuo." ”

"It's easy." Li Qiuyu replied, only to see Li Qiuyu snap his fingers, and the ingredients in the pot turned into powder.

These powders floated into the air under the control of Li Qiuyu's thoughts, and then a ball of flame shot out, enveloping this mass of powder.

"Your fire is a demon fire, isn't it?" Chu Yuan said.

"Yes, the slave and maid are cultivating the Demon Dao, and this is the Demon Infant Fire of the slave and maid."

"Demon fire is more gloomy than Danhuo, it is easier to remove impurities, and it is better to use it for alchemy." Chu Yuan said that this was what he saw on the "Compendium of Spirits".

Li Qiu let out an "oh", thinking that there is still this kind of statement, it is really a long experience.

At this time, some liquid seeped out of the wrapped powder and fell to the ground.

This is when the impurities in the material are cleaned out.

At this moment, Chu Yuan said: "Okay, you can stop, I'll take over now." ”

Li Qiuyu listened to this, withdrew the demon fire, and withdrew the demon sense, only to see that the powder in mid-air had turned into a transparent colloid.

Chu Yuan used his mind to control the shape of those transparent colloids, and after a while, a complete set of chemical reagent bottles such as transparent glass test tubes, beakers, and hourglasses were formed, waiting to be formed one by one after cooling.
