On this day, Gu Hong first told some of the basic knowledge of alchemy, including medicinal materials and Danhuo, as well as the process of alchemy, Gu Li listened very seriously, after all, this is a way out of his current situation, but some of the other disciples of the Demon Yuan have no spirit, and halfway through the lecture, almost half of them have already fallen their heads.

There was no accident, these people were all cleaned up by Gu Hong, as for what was cleaned up...... A bright red flame flashed in Gu Hong's hand, and as soon as the flame came out, many people looked at it in surprise, and the same was true for Gu Li, which I talked about in the lecture just now - Danhuo!

"Six-rank Danhuo, it should be enough for you hairy boys to bear ......" Gu Hong showed a sinister smile on his face, his eyes locked on the few Demon Yuan disciples who were squatting in the corner.

Several Demon Yuan disciples were trembling with fright at this time, not knowing what would happen when they waited, the next second, Gu Hong threw out the Dan Fire in his hand, and it just fell into the pile, just touched, the Dan Fire exploded instantly, enveloping several disciples.

Danhuo is very peculiar, it did not burn its clothes, but hurt its flesh through its clothes, this should be Gu Hong's control when he was teaching, it can't be explained by oral description alone, but now it's good, someone will cover it up.

Several disciples screamed under the Dan fire, the green tendons on their faces burst out, their hands clenched into fists, and they collapsed to the ground, and the people next to them felt pain just by looking at them, let alone experiencing it personally.

After about half an hour, Gu Hong waved his hand to summon the Danhuo back, and he shouted at a few disciples who had collapsed on the ground: "This is the first warning, and the only warning, the next time you do it again, I will refine you into a Dan!" ”

It is estimated that a few disciples have regretted it to the bottom of their bones now, what kind of alchemy do they have to learn if they have nothing to do?!

Next, Gu Hong walked to the center of the hall with the Dan Fire in his hand, took out a small Dan furnace from the storage ring, and said loudly: "Let me show you the process of alchemy......

I saw that the momentum on Gu Hong's body skyrocketed, and his blood and qi swelled, and in the blink of an eye, it enveloped the entire Dan Palace, and the small Dan furnace hung in the air, and the Dan fire in his hand was also eager to try, ready to jump into it at any time, and after the minute, the Dan Huo rushed into the Dan furnace, and the terrifying momentum made all the people present stand on end.

Gu Hong immediately introduced the prepared medicinal materials into the Dan furnace one by one, there was a small opening in the center of the electric Dan furnace, and the people present could clearly see the situation inside, and the medicinal materials that were put in turned into a pale golden liquid, surging in the Dan furnace.

Gu Hong's control of the opera pill fire is extremely subtle, and the temperature of the six-pin pill fire is extremely terrifying, but at such a temperature, the medicinal materials can still be stably maintained in a liquid state, and it should not take long to become a pill.

In the entire Dan Hall, there was only the faint sound of flames and the sound of the furnace grinding, because of the previous lesson, no one was dozing off or having the idea of disturbing, and they all watched quietly.

Soon, the Dan Hall was filled with a unique aura, exuding bursts of medicinal fragrance, and then accompanied by a faint golden light, the entire medicine refining process also entered the end.

Suddenly, the lid of the Dan furnace was lifted by Gu Hong, and a little golden light flew out of it, it was a pill by pill, one, two, three...... A full fifty pills!! Fifty pills in one furnace, that's quite terrifying?!

Gu Hong didn't have much expression on his face, and with a wave of his sleeves, all fifty pills were put into the medicine bottle on the table, and his movements were smooth, and he looked extremely skillful.

He put the Dan furnace and Dan fire back and continued. "This is a first-grade pill condensing pill, it is not difficult for beginners...... "Then he explained in detail the usage and refining details of these pills.

Dandian had only been teaching for an hour, and it passed in the blink of an eye, and when he was leaving, Gu Hong stopped him, as if he was not surprised by Gu Li, and there was no expression on his face.

After a while, there were only two people left, Gu Li and Gu Hong, Gu Hong stared at Gu Li with deep eyes, and threw a medicinal herb, a Dan furnace, and a storage ring to him. "I won't talk about the medicinal herbs, today you go back and refine a condensing pill for me, if you can't refine it, you won't use it tomorrow, if you don't practice well in the body refining realm, what kind of alchemy can you learn?!"

Gu Li wrinkled and didn't come back to his senses for a long time, if he wanted to say yes, he was afraid of overturning, and if he said no, he was afraid of being kicked out directly, after weighing the pros and cons, he still nodded, and walked in the direction of his wooden house with the medicinal herbs.

"There is only one medicinal herb, I don't believe you can really refine it......"

……

That night, Gu Li noticed that the medicinal materials given by Gu Hong were really only the amount of the required medicinal materials, and he didn't bring any extra ones, he secretly scolded the dead old man, and then his eyes fell on the storage ring, no surprise, this is - Danhuo!

As soon as his mind moved, the Danhuo appeared in Gu Li's hand, the Danhuo flame was very small, and the color was several times lighter than that used by Gu Hong, it should belong to the ranks of the first-grade Danhuo, its preciousness was far less precious than the six-pin, and its alchemy effect was the same.

Gu Li scratched his head, now he could only try it hard, he recalled every detail of Gu Hong's display today in his mind, and at the same time, his eyes looked at the Dan Book and looked at it, this was taken by Gu Li in the Hidden Scripture Pavilion when he came back, and he spent more than a hundred high-grade blood crystals, and he almost didn't write the word robbery directly on his face.

After a long time, Gu Li put down the book in his hand, and looked at the Dan furnace on the table with solemn eyes, and the mountain-like blood crystals stacked next to him.

Because he was in the refining realm and did not give birth to blood qi, and he needed to use blood qi to control the Dan fire when refining the pill, he could only use blood crystals instead, as for how much he needed, Gu Li didn't know, so he had to take them all out and pile them up beside him.

With the sound of "click", the alchemy officially began, Gu Li tried his best to keep himself in a calm state, Gu Hong said in the Dandian that the more impetuous, the lower the success rate of the pill.

Hesitating Gu Li's deliberate control, this time the blood and qi in the room did not rush towards him as if he was crazy, but this control was really energy-consuming, under its traction, countless blood and qi rushed to Danhuo, and Danhuo also began to go crazy at this moment, and the sparks that erupted several times almost burned the house.
