Enter the second stage, refining. Yun Lin needs to concentrate on controlling it, after all, the demon fire is alive. It's like a fisherman asking a pelican to catch a fish, you have to watch. Otherwise, you'll eat all of it! When it's full, it won't catch fish!

The same is true of demon fire, they are instinctive to eat, demon fire is alive, but the intelligence is not high, it is similar to ordinary beasts, it needs to be domesticated, and the degree of your domestication is related to your own strength. When the demon fire enters the second stage, you just force it to refine the medicinal powder and eat as few medicinal materials as possible. And to limit the demon fire is to use spells to restrain him. Of course, there is also a means to use magic weapons to restrict, but Yunlin doesn't have that kind of high-end goods, so he can only use spell restrictions.

About Hongshu, it was basically taught to him by Linlang. Linlang also said that the advantage of magic weapon restriction is that you don't need to consume your own strength too much. But the advantage of spell restrictions is that they can do whatever they want, and they can squeeze the demon fire as much as possible.

Of course, high-grade magic weapons can also do it, but this kind of magic weapon can be encountered but not sought. It's as simple as that, and the spell restricts the ability to practice its own witchcraft, and there is no place to perform witchcraft in the first place, so it is not used here. Then there really is no place to cultivate.

Yun Lin immediately used the forbidden spell to limit the devouring progress of the demon fire, and the demon fire had more black lines on its body, with three lines, tightly binding the demon fire, so that the demon fire continued to produce ashes.

Although the process doesn't seem to be difficult, it's really not easy, the spells of witchcraft are much more difficult to launch than the spells of Taoism, witchcraft is super difficult to learn, there will be a lot of spells in Yunlin Dao, but witchcraft spells will be a lot at present, and they are all housekeepers, and they dare not be exposed.

This forbidden spell is one, and the forbidden spell is called the Black Magic Spell. No one knows what the specific principle is, but anyway, they know that this is one of the forbidden spells.

Yun Lin kept chanting a very old, jerky and difficult word in the innermost. It's not any language spoken today. The language is ancient and difficult to understand. Yun Lin was familiar with the chanting spell, and the demon fire continued to shake out black powder.

The sweat between Yun Lin's foreheads continued, and it didn't take long for the sweat to wet his clothes.

Zifeng looked at Yun Lin worriedly, but not long after, Yun Lin put away the flames and said, "Okay." ”

The flames returned to the palm of his hand, and then disappeared, leaving a furnace full of black powder in the furnace, Yun Lin smiled and said, "It's done!

Yun Lin put the powder into his pocket, this time a small bag was not fitted! Yun Lin took out another pocket, and another small bag also contained half a bag of medicinal powder.

Guo Yuanyuan held back for a long time, and only then did he dare to ask: "Master Yunlin, I have a reluctant request, and I hope that the master can fulfill it!"

Yun Lin looked at Guo Yuanyuan curiously and asked, "Is there something wrong with Guo Lao?"

"I hope Master Yunlin can take me as an apprentice!" Guo Yuanyuan knelt down as he spoke, and Yunlin hurriedly said, "Old Guo, what are you doing here?"

Guo Yuanyan said with admiration: "I really admire your alchemy just now, I don't know if the master can teach me something that I can learn." I have been infected in the circle of Chinese medicine all my life, and I have been hoping to learn more medical skills all my life. ”

Yun Lin hesitated: "But...... You are my master's deceased, how can I?"

"What's this, the world's skilled people come first. Especially in traditional Chinese medicine, it is even more respected. We are friends, but don't delay me from worshipping you as a teacher!" Guo Yuanyuan knelt on the ground very sincerely, and had no intention of getting up at all.

Yun Lin looked at Zifeng, and Zifeng hurriedly said: "What Guo Lao recognizes, he will definitely not change." ”

Yun Lin sighed and said, "This ...... Okay, but you're old, I'm afraid it's too late to cultivate, but if you want to learn from me, you can start learning from Fangshu, Fangshu is also an important skill, after learning Fangshu, you can prepare yourself with life-prolonging drugs, and after you have some spiritual power, you can perform Zhuyou and alchemy. That's your limit, I guess. ”

"Thank you, Master! Apprentice Guo Yuanyuan bowed to the master, and is willing to follow the master for the rest of his life and learn medical skills!" Guo Yuanyuan kowtowed three times, and Yun Lin said with a smile: "Okay, that ......" Guo Yuanyuan called Master Yun Lin, so that Yun Lin didn't know what to call him.

Yun Lin thought for a moment, and then said with a scalp: "Yuanyuan, you get up first, and if you talk about it to the outside world, you still don't mention our master-apprentice relationship." After all, you are a veteran of fame and need fame. And I don't want to be disturbed, you know?"

Guo Yuanyuan nodded respectfully and said, "Everything is up to Master." ”

Yun Lin sighed, then went back to the room and took out a leather notebook from his pocket and said, "This is the study diary I wrote down when I was studying Fangshu, and it contains my experience and insights. There is also a method of learning alchemy. Take it and take a look!"

Guo Yuanyun's hands trembled and he turned out the leather diary, and after he opened the diary, he found that in this black leather notebook, Yun Lin had neatly written down all the notes.

Guo Yuanyun held the notebook in both hands like a treasure and said, "Thank you, Master!"

Yun Lin nodded, and he said calmly: "Don't call me master, just call me teacher! ”

"This ......"

Zifeng hurriedly played the round and said, "Old Guo, I think it's good to call the teacher! Calling this won't make Teacher Yunlin feel so uncomfortable!"

Guo Lao thought for a moment, then nodded and said, "Okay, teacher." Then everything is up to you. ”

Yun Lin smiled and said, "Okay, okay! Yuan Yuan, you learn this diary first, and if you don't understand something, you have to ask me." At least I'm in the Dragon Court for this time!"

Guo Yuanyuan nodded and said, "Okay, I'll ask you if I have any questions!"

Zifeng looked at the refined medicinal powder, and she asked curiously, "Is it time to treat me?"

Yun Lin said calmly: "Well, it doesn't need to be difficult, you go to my bed and lie down, and I'll give you a pull!"

Zifeng was lying on Yunlin's bed with joy, and when she thought that this bed was where Yunlin was lying, her heart fluttered and fluttered. Yun Lin still put a stick of incense in Zifeng's mouth as usual, and after the incense was lit, Yun Lin then put a yellow talisman in a paper cup and used the talisman fire to ignite the medicinal powder. Yun Lin pulled out the incense, and then used the glass to buckle it to Zifeng's mouth and nose. It didn't take long for Zifeng to inhale the smoke and begin to feel a strong feeling of nausea.

Zifeng hurriedly ran to the bathroom, and Yun Lin asked her to spit into the sink, and water was also placed in the sink.

Zifeng spat out some black liquid in front of Yun Lin, and then squirted a mouthful of red blood. Yun Lin nodded with satisfaction and said, "Very good, Yuan Yuan." Come over here. ”

Guo Yuanyun walked over humbly, he stood aside respectfully, Yun Lin pointed to the things in the sink and said: "The first time Sister Zifeng spit out is Gu poison, and the Gu poison is produced by the Gu worm itself to excrete toxins in the body. I activated the anti-poisoning effect of the powder. As for the second mouthful of blood, it was not her blood, but the Gu worm that exploded. ”

Zifeng couldn't help but vomit, Yun Lin pointed to the toilet and said, "Go over there and vomit." ”

Zifeng covered her mouth and went to the toilet to vomit. Guo Yuanyuan asked curiously, "Then what are you vomiting now?"

Yun Lin smiled and said, "Just because it's disgusting? Aren't you disgusted if you have bugs in your stomach?"

Guo Yuanyuan couldn't help laughing, he nodded hurriedly and said, "Yes, yes, I know." ”

Yun Lin said with his hands behind his back: "Once the poison of the Gu worm is pulled out, you must not touch it. Because the toxins of Gu worms are easy to carry eggs, so you should pay attention to this kind of thing when you deal with it, boil realgar in boiling water, add some cinnabar and mix well, then add glutinous rice flour and pour these things in. Let's see what the effect is. ”

Yun Lin took the electric kettle and lost a pot of water as he spoke, and then poured it into an iron basin, and he put everything he said into it. After mixing well, pour it into the sink, and then the inside began to bubble, and when the foam receded, the water in the sink turned into sewage, and you couldn't see the sticky feeling!

Yun Lin said with a smile: "In this way, all the Gu worms will be completely killed." Sister Zifeng, you have to clean up the good things you did for me. Yun Lin's face pointed to the sewage in the sink with a narrow smile, and when he saw the sewage, Zifeng couldn't help but want to vomit......
