Li Xuangang followed Li Changji to the edge of the rockery, and then Li Changji cast a spell, and after a huge wave of spiritual energy, he saw the rockery crack open from the middle, revealing a passage to the underground.

While walking down, Li Changji reminded with words:

"Follow me, be careful not to touch the circle. ”

Before, when Li Changji didn't use his spiritual power, Li Xuangang didn't feel anything by his side, but now Li Changji just opened a magic circle and let himself feel a terrifying pressure.

Li Xuangang calmed down and forcibly calmed down under this coercion.

Li Xuangang thought to himself: Is this the power of a foundation building monk? No wonder he can fly with qi, no wonder a foundation building period monk is so important to the family, and the power of the foundation building period is simply incomparable to the qi refining period.

If the Eighth Uncle encountered that group of loose cultivators in the Black Wind Ridge, I am afraid that he would be able to solve the other party by casually sacrificing a few flying swords or a few offensive spells.

In fact, just by opening a magic circle, Li Changji originally didn't need to leak such a powerful aura fluctuation, and this move inevitably didn't take Li Xuangang's consciousness into account.

Seeing that Li Xuangang quickly returned to normal, Li Changji was even more satisfied with him.

He thought to himself: "Even if he doesn't have any talent in alchemy, but with this little bit of heart alone, it is still very likely that he will go further on the path." ”

Finally, after following Li Changji through this passage, a wide underground cave appeared in front of Li Xuangang.

This underworld can be said to be the most important place in the Baicao Pavilion, because this is the place where Li Changji alchemy.

The first thing that caught Li Xuangang's eye was a copper-yellow alchemy furnace in the center of the cave.

This should be the only second-order middle-grade alchemy furnace in the family, and there is also a second-order lower-grade alchemy furnace on the family Taiqiu Mountain, but it is shared by the entire family, and this one is said to be the private property of the eighth uncle.

Li Xuangang had heard that the eighth uncle had obtained a good alchemy furnace by virtue of his own chance in his early years, and he thought that this was it.

Li Changji walked to the side of the alchemy furnace, then turned around and said to Li Xuangang:

"This furnace is called Huangyang Jinjin Furnace, a second-order medium grade, and I got it by chance when I went out sixty years ago. I used it to refine the pill, and the first-order pill became a pill with a rate of seventy percent, and the second-order pill with a pill rate of fifty percent. For example, the second-order elixirs supplied to Taiqiu Mountain and Baicao Pavilion were all refined by me with them. ”

After that, Li Changji took out a small alchemy furnace from the storage bag, and then threw it at Li Xuangang, who hurriedly caught it.

"You take this first, and then you have to use it. Now stand next to me and observe the process of my alchemy, and after the refining is over, you can ask me if there is anything you don't understand. ”

While looking at the alchemy furnace in his hand, he replied:

"Yes. ”

Then Li Xuangang stepped aside, concentrated his energy, and began to observe seriously.

Most of the time, Li Changji was alchemy alone, although Li Xuangang was watching from the side at this time, it didn't have any effect on him, and after he gathered his spirit, he began to prepare for alchemy.

Then Li Xuangang saw that the eighth uncle Li Changji took out a fiery red stone, and with the appearance of this fiery red stone, the temperature of the entire underground cave increased sharply, and a wave of heat spread outward with that stone as the origin.

Just when Li Xuangang was puzzled, Li Changji spoke:

"This stone is called the Fire Source Stone, which can be used as a furnace fire for alchemists when they are alchemists, although compared to the fire with earth or the fire of the Jindan monk, the alchemy effect is not so good, but it can be alchemy anytime and anywhere, and it does not need to be fixed in one place like a fire with a fire. Second, it is easier to focus on condensing Dan than simply using Danhuo, and the rate of becoming Dan is higher. ”

Huoyuan Stone Li Xuangang knew, but this was the first time he had seen the real thing.

He recalled the introduction of the Fire Source Stone in the family texts. The fire source stone is an ore condensed in the fire attribute vein, the output is not much, the fire is mild, the low-level fire source stone is mostly used for alchemists to assist in alchemy, and the high-level fire source stone is generally used to refine the fire attribute magic weapon, generally each fire attribute vein can only condense no more than three high-grade fire source stones, each high-level fire source stone is located in the deepest part of the fire attribute vein, and the above monks of the non-Jindan realm cannot reach it, so each fire source stone is extremely precious.

According to Li Xuangang's observation, the eighth uncle's fire source stone should be a low-level one, because although the heat it emits is terrifying, Li Xuangang can still withstand it, if it is a high-level fire source stone, Li Xuangang estimates that he will have to burn it into charcoal immediately.

"I will refine the Yanggu Pill first, this Pill is a first-order low-grade spirit pill, suitable for monks in the early stage of Qi refining, the pill you will practice in the future is mainly this Dan, you pay attention to my technique now. ”

Yanggu Dan Li Xuangang was quite familiar with it, because this was the pill he mainly took in the early stage of Qi refining, which was refined from Linggu and the other five different low-level spirit grasses, three of which he had also cultivated in the medicine garden of Taiqiu Mountain.

Li Changji first took out a small pile of Linggu and sent it into the Huangyang Jinjin furnace, and then controlled the fire source stone to slowly dissipate heat until the Linggu in the furnace turned into a puddle of milky white liquid, and then Li Changji quickly took out five kinds of auxiliary medicines and put them into the furnace one by one in a specific order.

In this process, in order to take care of Li Xuangang, Li Changji deliberately slowed down his methods a lot.

After all the materials were turned into liquid and fully fused, Li Changji sealed the Huangyang Jinjin Furnace and began the most critical step in alchemy, which was Ning Dan. The success or failure of alchemy mainly depends on this step, but Li Changji, as a second-order alchemist who has advanced for many years, is still very handy with Yanggu Dan, a first-order low-grade elixir, so he is not very careful about this step, and while controlling the Ning Dan, he also turned his head to explain the main points to Li Xuangang.

"Xuan Gang, you have to pay attention to the proportion of materials, the time it takes to turn into liquid medicine, and the control of the temperature of the alchemy furnace when condensing the pill. ”

"Obey the teachings of the eighth uncle. ”

"When this furnace Dan is finished, I will burn a copy of Yanggu Dan's Dan Fang for you, and you will study it well when you go back, but remember that the Dan Fang is well kept, and it is strictly forbidden to pass it on to outsiders. ”

"Xuan Gang knows the stakes, and the eighth uncle doesn't have to worry. ”

Danfang is one of the most precious things for every alchemist, and it is also precious for a family, and the value of a Danfang is huge, which is equivalent to providing a stable source of spirit stones for the family.

Three quarters of an hour passed, Li Changji opened the Huangyang Jinjin Furnace, and suddenly there were eight round yellow pills scattered at the bottom of the furnace, which were Yanggu Pills.

"Cheng Dan rate is eighty percent. ”

Li Changji nodded with satisfaction, and with a move of his hand, he received the eight Yanggu Pills in his hand, observed them, and found that the condition was not bad, and then threw the eight Yanggu Pills to Li Xuangang.

"These eight Yanggu Dan will be given to you, after you go back, break it open, combine it with the Danfang, and see the ingredients and structure inside. When you're almost done, you can try refining it with the alchemy furnace I just gave you. ”

Li Xuangang accepted the eight Yanggu Pills and nodded.

Then Li Changji took out another jade cylinder and handed it to Li Xuangang, which was the Danfang of Yanggu Dan.

Coupled with the non-advanced alchemy furnace that he threw to himself before, he can be regarded as having gathered all the items for alchemy, as for the materials of Yanggu Dan, Li Xuangang can withdraw them in Baicao Pavilion every month, which is also a benefit given by the family in order to cultivate alchemists.

"I'll give you time for two sticks of incense, now take a look at Yanggu Dan's Dan Fang, and then if there is anything you don't understand and what you don't understand in the alchemy process just now, you can ask me. ”

When Li Xuangang heard this, he immersed his divine sense in the jade cylinder and looked at the Dan Fang carefully, of course, he couldn't completely think about it in such a short time, but he just looked at the shallowest part.

After two sticks of incense, Li Xuangang mentioned a few things that he was a little puzzled about, and Li Changji answered them one by one.

In the end, Li Changji even mentioned some problems in cultivation, and Li Xuangang naturally didn't dare to slack off, and listened with a condensed spirit.

It wasn't until the early morning of the next day that Li Xuangang came out of the underground cave mansion and returned to the backyard of Baicao Pavilion.

And Li Changji is still inside, he is going to refine the tasks assigned by the family, every three months or so, Li Changji will come to refine a batch of first-order elixirs and second-order elixirs for family consumption and Baicao Pavilion sales.

Before coming out, Li Xuangang clearly saw that the eighth uncle Li Changji took out a batch of Zhu Dan grass, and thought that the eighth uncle should be refining the red jade pill. Then he thought that in his storage bag, there were still three Zhu Dan grasses and six Zhu Dan grass seeds.

Li Xuangang stood there quietly for a while, digesting the experience he had just gained.

Then he walked towards the streets of Marina City.

Li Changji comes to alchemy every three months, and usually cultivates in the cave mansion in Binhaifang City, so Li Xuangang only needs to come every three months, and then he will ask the eighth uncle for advice on what he doesn't understand when he goes back to practice.

Of course, Li Xuangang naturally wouldn't waste these three months, and he was going back to the cave he rented to cultivate. However, before going back, Li Xuangang decided to go to a place.

In the bustling crowd, Li Xuangang chose a direction, and then walked forward, his steps firm and powerful.
