Li Tianyi's words made Jiang Ning not know how to answer, and the alchemy technique of the earth was so similar to the Heavenly Dome Continent a long time ago.

The method of spiritual liquid extraction must have spiritual power, otherwise the material will be burned directly in the fire, even if it is placed in a container, the spiritual liquid of the material will evaporate, and finally become a dry waste, and it is impossible to collect the spiritual liquid, if it was a long time ago, the alchemy of the earth was also a method of using spiritual liquid extraction, that means that in ancient times, the spiritual power on the earth was more abundant than now, and there were cultivators.

Jiang Ning had this kind of speculation before, because when a martial artist cultivates to the day after tomorrow, his body will produce true qi, and this true qi is similar to spiritual power, but even so, no direct evidence can be found, all this is still just speculation.

"I know how to extract spiritual fluid, my master taught me. ”

Jiang Ning said with a flat expression, and then threw this troublesome matter directly onto the fictitious master.

Looking at Li Tianyi's excited expression before, he must ask Jiang Ning where he learned this spiritual liquid extraction method, Jiang Ning didn't want to expose too much information about the Heavenly Dome Continent, so that even if Li Tianyi asked, Jiang Ning could push everything else on his fictitious master.

"Little brother, take the liberty of asking, who is your master, where is he now, can you introduce it to the old man?"

Sure enough, Li Tianyi continued to ask, but fortunately, Jiang Ning had expected it in advance.

"My master likes the life of the idle clouds and wild cranes, and his old man is now wandering around, and I can't find it. ”

"Then where did you learn from your master?"

"I don't know, he didn't tell me......"

"Then your master ......"

Li Tianyi still continued to ask, but Jiang Ning had the shield of "master", and it was easy to deal with it.

"Daochang Li, please help keep the matter of the tutor confidential, the tutor has a strange personality, and he doesn't like me to mention him in front of people. ”

Jiang Ning then asked Li Tianyi, in fact, Jiang Ning just wanted Li Tianyi not to tell Lin Zhengyuan, but it was not easy to say it directly, after all, Lin Zhengyuan knew that Jiang Ning's "master" was made up by himself, and Li Tianyi was Lin Zhengyuan's friend, if Lin Zhengyuan knew that Jiang Ning even lied to Li Tianyi, I am afraid that it would be a little embarrassing to meet.

"Don't worry, old man is not the kind of person who chews his tongue. Li Tianyi nodded with a smile, and then continued: "Little brother, the spiritual liquid that extracts these materials will be handed over to you." ”

Li Tianyi couldn't get the answer he wanted, and finally gave up, and then thought that it was also excellent to observe Jiangning's extraction.

"Leave it to me. Jiang Ning nodded.

I didn't care too much about this Jiang Ning, after all, I had been reborn for so long and had fought with masters of all levels, and the other party didn't see anything different about Jiang Ning.

Then Jiang Ning picked up the purple spirit vine and put it in the palm of his hand, and the spiritual power in his body was condensed in the palm of his hand, and then the other hand volleyed on the purple spirit vine, and both hands released spiritual power at the same time, wrapping the purple spirit vine in the air.

Li Tian looked at Jiang Ning intently, and even his breathing slowed down, for fear of affecting Jiang Ning.

Then Jiang Ning controlled the purple spirit vine and slowly transferred to the furnace ding, only to see that the flames in the furnace ding suddenly rose a little, and the flames directly swallowed the purple spirit vine.

"This ......" Li Tianyi tensed for a moment and wanted to speak, but quickly controlled it.

He didn't expect Jiang Ning to put the materials directly in the fire, he thought that if he did, he would definitely burn the materials, which was no different from waste.

But the purple spirit vine was wrapped by Jiang Ning's spiritual power, and the flame couldn't touch the purple spirit vine at all, but the high temperature in the flame would pass through the spiritual power, and under the action of heat, the purple spirit vine gradually withered, but a few drops of liquid gradually condensed on the purple spirit vine, if you didn't observe it carefully, you really couldn't see it.

About 15 minutes later, the purple spirit vine dried up completely, and there were more than a dozen drops of the extracted spiritual liquid, and the spiritual liquid was wrapped in Jiang Ning's spiritual power, and then I saw Jiang Ning stretch out a finger, and then the finger crossed the side of the spiritual liquid, and the dried purple spirit vine lost control and fell directly to the ground, and the extracted spiritual liquid was suspended between Jiang Ning's fingers.

"Amazing, just amazing. ”

Li Tianyi kept admiring, and the expression on his face was also very surprised.

Jiang Ning took a bottle from the side, gently put the spiritual liquid into the bottle, and then used the same method to extract the remaining dozen or so materials into spiritual liquid one by one.

These materials are not as difficult to extract as the purple spirit vine, each material does not take more than five minutes, and after about an hour, the previous materials have turned into dry shells, and at the same time, more than a dozen bottles of spiritual liquid of materials have appeared.

"Daoist Li, the spiritual liquid has been extracted, and the rest is up to you. ”

Jiang Ning said and wiped the sweat on his head, although it was much easier to extract the spiritual liquid than when refining, but more than a dozen kinds of medicinal materials, refining for more than an hour in a row, also had a certain consumption of spiritual power.

"No problem, leave the rest to the old man, this elixir is expected to take about seven hours to refine, and the old man will always be by the alchemy furnace during this period. ”

Although the alchemy techniques on the earth do not test the spiritual power and control power like the Heavenly Dome Continent, when refining the pill, they also need to stay by the alchemy furnace all the time, observe the changes in the alchemy furnace, and make corresponding adjustments, which is also a great test for the experience and perseverance of the alchemist.

Jiang Ning and Lu Daochang left the alchemy room, Jiang Ning didn't know how to spend the seven hours, and there was also news from Lin Zhengyuan's side, saying that Lin Xueyao still hadn't lost his breath, and now going to Lin Xueyao was tantamount to hitting the muzzle of the gun, and finally Jiang Ning decided to cultivate, and then sat cross-legged in a remote and quiet place in the Lin family manor, and Xiaoyun Jue quietly operated.

I don't know how long it took, Jiang Ning slowly opened his eyes, and the aura in the Lin family's manor was also very thin, but this cultivation at least made up for the spiritual power consumed before, so it was not a waste of time.

The scorching sun was in the sky, the sun had already crossed the middle line and gone to the other side, Jiang Ning looked up and knew that it was already past noon, and then got up and walked slowly towards the alchemy room.

But when Jiang Ning was about to walk to the door, he suddenly felt a strange aura fluctuation coming from the alchemy room, and Jiang Ning actually felt that this aura had a violent aura.

Jiang Ning hurriedly quickened his pace, and then suddenly pushed the door in, only to see that in the alchemy room, Li Tianyi was sweating profusely, constantly controlling the alchemy furnace.

"Senior brother, hurry up and open the valve of the Xun position. ”

"Okay, it's open. ”

The gate opened. ”

"Okay, it's open. ”

This alchemy furnace is built according to the eight trigrams, and eight valves are set according to the direction of the eight trigrams, which is the only place on the earth where the alchemist needs to control, because the inside of the alchemy furnace cannot be considered to be controlled, so only through these eight valves, and then according to the experience accumulated by the alchemist for many years, the alchemy furnace can be controlled.

Li Tianyi continued to command Lu Daochang, his brows furrowed deeply, and he continued to observe the changes in the alchemy furnace.

"Daoist Li, what's going on?" Jiang Ning asked anxiously.

"Little brother, it's not good, I'm afraid this Dan can't be refined, if it doesn't stop now, I'm afraid there is a danger of exploding!"
