Zhao Feiyu looked towards the box, and saw that there were many boxy wooden lattices in the box, and in each wooden lattice, there were herbs of different shapes. It is from these plants and trees that the extremely fragrant smell of plants and trees emanates.

On the far right side of the box, there is a long and narrow lattice, in which a jade slip is placed.

Zhao Feiyu took the jade slip in his hand with ease, and then gently pasted it on his eyebrows.

A huge and complicated soul thought instantly poured into Zhao Feiyu's mind.

What was recorded in it was a spell for cultivating elixir, but it was just the most basic alchemy method.

In addition to that spell, there are also several pills, which record the method of refining pills.

Zhao Feiyu did not practice the spell of refining the pill, but first checked the few pills.

After a while, Zhao Feiyu slowly opened his eyes and couldn't help but sigh lightly.

"This refining pill is completely different from what I imagined, it is so complicated." Zhao Feiyu couldn't help complaining, he suddenly thought of the means that Gu Xuan had taught him when he was refining the elixir in the Spider Demon Beast Valley, he only needed to turn the spiritual energy of heaven and earth into spiritual energy flames. It is used to burn the herbs in the yellow clay furnace, and all of those herbs will turn into a puddle of liquid, and then slowly form the shape of an elixir. It is extremely convenient to refine.

What is recorded in the current pills is completely different, and those pills not only require a variety of herbs as raw materials. And in which herb to put into it, in what heat is quite particular. Moreover, the temperature of the aura flame must also constantly change with the refining process, otherwise the previous efforts will be wasted.

"These Dan recipes seem more complicated than the chemistry experiments I learned in high school." Zhao Feiyu couldn't help complaining, he suddenly thought of the chemistry course he had studied in high school.

Those are quite complex chemical experiments. Those headache-inducing chemical equations. It's all a painful past that can't be looked back on.

At present, it seems that the process of refining those elixirs is far more complicated and difficult than doing some chemical experiments.

The most important thing is that doing chemistry experiments in school doesn't cost anything. All the raw materials and equipment were provided by the school, and at present, many plants and trees need to be found by themselves to refine those elixirs. Otherwise, you have to go to the stall outside and buy it.

Once the refining fails, all the plants and trees will turn into ashes, without the slightest use value, which is undoubtedly an extremely difficult thing for Zhao Feiyu, who is not rich in his own family.

It's not just that the process of refining the elixir is extremely complicated, and if you are not careful, you will fail. is even more because Zhao Feiyu can't afford to buy or find all kinds of plants and trees.

And some of the herbs in this box are all gifts given to him by Senior Brother Zhang, so that he can use them as props for hand training.

But it was obvious that Senior Brother Zhang would not provide him with a steady stream of various herbs, and in the end, he still needed to collect all kinds of herbs by himself in order to be able to cultivate the Dan Dao.

"No wonder there are so few people refining pills, not to mention that those pills are extremely difficult to collect, if it is a casual cultivator, it is impossible to find a few decent pills, but also because if a monk's own strength is not able to collect all kinds of herbs for refining, only with the support of the sect or family power will there be enough foundation to refine pills, it seems that the monk who refines the pill must have a solid family background." Zhao Feiyu couldn't help but sigh.

Zhao Feiyu was about to close the box, he couldn't bear to refine the pill at will and waste all these precious herbs, but he suddenly had a thought, picked up a herb, and held it in front of him.

Zhao Feiyu looked at the identity ring on his hand, and suddenly remembered that this was also a so-called space ring, in which there was about two square meters of space, which could store some things.

It's just that Zhao Feiyu doesn't know how to use this storage ring at the moment.

Zhao Feiyu stared at the herb stubbornly, thinking with his mind about letting this herb enter his storage ring, but Zhao Feiyu stared at that herb like a big eye, and there was no reaction for a long time.

"Young man, you really want to laugh at me." Sander's words came to mind in Zhao Feiyu's mind.

"I just want to give it a try, do you have any high opinions?" Zhao Feiyu asked.

"That's not how storage rings are used." "You have to wrap your soul mind around the object you want to put in the storage ring, so that you can connect with the storage space in the storage ring and put the difficult object into the storage space. ”

Hearing Sander's explanation, Zhao Feiyu nodded slowly, "I see." ”

Zhao Feiyu's eyebrows emanated a wisp of soul thought, and it wrapped around the herb, and then his mind moved, and the storage ring emitted a faint white glow, and the herb in Zhao Feiyu's hand disappeared instantly.

Zhao Feiyu looked at his empty right hand in surprise, and hurriedly transferred his mind to the storage space.

I saw that in the gray space, the herb was floating in it.

The storage space was like a gravityless space. The herbs don't fall to the ground, they float in mid-air.

Zhao Feiyu's heart moved, and the herb appeared in Zhao Feiyu's hand, as if it was magic.

"It's amazing, if I had a storage ring like this in the real world, wouldn't I have become a world-famous magician, and no one would have been able to see through my methods, and they would never have thought that it was because I had a storage ring to be able to perform such a magic show." Zhao Feiyu laughed and wrapped his nostalgia around the herbs again.

The herb disappeared in Zhao Feiyu's hand, and it reappeared and repeated for more than ten times.

Zhao Feiyu's soul suddenly felt a faint feeling of sleepiness, causing Zhao Feiyu's body to suddenly stumble and almost fall to the ground.

"What's going on?" Zhao Feiyu muttered with a puzzled expression.

"I want you to see that you just wrap a wisp of soul power around that grass and tree. But repeating it dozens of times in a short period of time will still make your soul feel a sense of fatigue, but fortunately, the tenacity of your soul is extraordinary. Otherwise, you will faint in an instant. Sander opened his mouth to explain, "This storage ring is not something that a cultivator of an environment can play with at will, and if you can freely operate the ring in the mortal realm, it means that your divine soul cultivation is already very extraordinary." ”

"What you have to do right now is to improve your cultivation as soon as possible, so that you can step into the Xuan Realm as soon as possible. That's when you really step into the path of cultivation. Many things can be operated calmly. Sander said bitterly, "The thunder spirit veins in your body are still in a dry state, and I think you need to undergo a thunder baptism." to be able to return to the true state. ”

"Don't, don't!" Zhao Feiyu hurriedly waved his hand, "I'm pretty good now, I don't want to be struck by lightning yet!" ”

Zhao Feiyu saw that Sand was speechless. Gently relieved. Look into the wooden box again.

Open the second layer of the wooden box, and there is a round small tripod in it.

That small tripod was obviously a medicine tripod for refining herbs and trees, and the surface exuded a milky white color, like a small tripod made of jade.

Zhao Feiyu gently took the small ding in his hand, and a cold touch was transmitted instantly.

Zhao Feiyu knew that this jade tripod was an extraordinary thing, and it contained an aura that was like nothing, and it was obviously a high-grade magic weapon.

Zhao Feiyu imitated the way he manipulated the storage ring before, and poured a wisp of soul power into the jade tripod.

The surface of the jade tripod instantly emitted a faint white glow, and then slowly dissipated.

Zhao Feiyu gently let go of his right hand, and the jade tripod floated quietly in mid-air, slowly spinning.

"Damn, it's amazing!" Zhao Feiyu couldn't help but sigh with emotion, "This thing can actually break free from the shackles of gravity and float in mid-air." It can't be some kind of superconductor material, right? If I could bring this material to the real world, wouldn't I make a lot of money and become a famous person in the world? And these places use this magical material just to refine some pills, which is really quite a waste. ”

Zhao Feiyu gently dragged the jade tripod with his hand and placed it on the table.

Zhao Feiyu turned around and sat cross-legged on the bed, and began to comprehend the alchemy in the jade slip.

The basis of the alchemy is an introductory spell, which tells how to convert the aura into a spiritual flame, and then use the aura flame to scorch the medicine pot.

In the process of refining the elixir, how to control the strength of the aura, which also describes how to observe the color of the elixir. And then control the heat.

Once there is a certain change in the color of that elixir, it is the time to transform the spiritual power flame, and it is also the time to invest in other herbs.

However, if there is no quick grasp when the liquid medicine is transformed, then the elixir refined in this furnace will be scrapped in an instant and turn into a pinch of black ashes.

This law is extremely basic, and Zhao Feiyu mastered it in a very short time.

"Got it, got it, it's too easy." Zhao Feiyu hurriedly got up and poured a wisp of spiritual power into the jade tripod, which slowly floated in the air, slowly spinning.

Zhao Feiyu's heart moved, and an aura instantly gushed out from his right hand, and then hovered under the jade tripod.

"Burn!" Zhao Feiyu snorted lightly, and the aura instantly turned into a cyan flame, burning fiercely.

"Good guys, this is much better than natural gas." Zhao Feiyu couldn't help but sigh.

"Bigu Dan ......" Zhao Feiyu suddenly thought of the Dan Fang recorded in the jade slip.

Na Bigu Dan does not limit any specific medicinal materials, only more than two kinds of medicinal materials can be refined, but with the number of herbs and the size of its herbal medicine level will also determine the level of Bigu Dan, but only two of the most basic herbs can start refining Bigu Dan, which can be said to be one of the most basic pills, just like one of the means to get started.

"It's too simple." Zhao Feiyu casually picked two herbs and threw them into the jade tripod and began to refine them.

The two herbs instantly turned into a ball of medicinal liquid, and the fragrance of plants and trees instantly wafted through the room.

"I'm really an alchemy genius." Zhao Feiyu couldn't help but sigh.

The previous scene of refining pills in the Spider Demon Beast Valley instantly appeared in Zhao Feiyu's mind, and before Zhao Feiyu could react, the tip of his nose smelled a burning paste.

By the time Zhao Feiyu reacted, the jade tripod had already turned into a mass of pitch-black medicinal residue, without the slightest smell of grass and trees, and it exuded an unpleasant smell of burnt.

Obviously, Zhao Feiyu's first practice of Bigu Dan had failed.
