"My surname is Hao, and my single name is a mountain character... I am the most sensible person. It is best to speak. I can't remember your class hours, and will not restrain you from attending classes, and I will not go to the top to type your short reports. , Let you be punished! Therefore, it is my business, you can choose for yourself, you can come or not... If it is here, you don't want to listen, it's okay, you can sleep and play, whatever you like!!!"

He bowed his head slightly and straightened his clothes.

"But one thing, all my lessons will only be taught once. If you hear it, then you hear it. If you can't hear it, then it depends on your own destiny..."

Full Moon glanced at the people coldly, then raised her lips coldly: "Don't you shame me!! I am full moon, I can't afford to lose that person!!!"

Compared with the fierce coldness of the full moon, Master Hao Shan is like a frog boiled in warm water, without rush or delay, without arrogance or impatience.

He just lowered his head to talk about his class, no matter if the Dan girls below understood or didn't understand, and no matter if anyone listened to what he said.

"Alchemy-some people say that the most important thing is the medicinal materials, and the medicinal materials determine the efficacy of the pill. Others say that the most important thing is experience... because only experience can determine the success or failure of a pill! But I think the most important thing is The pill fire...If you can't even control the pill fire, then there is no possibility of successful refining!!"

Hao Shan raised his head slightly, his eyes still calm.

"Pill Fire is divided into many types, how many of them are there, maybe you all know?!"

"I know..." You Dan girl was impatient and couldn't wait to say out loud.

Hao Shan's gaze came out calmly: "Since you know, then you can tell..."

The pill girl was quite proud: "I heard from the teacher at home that there are three types of pill fires, one is ordinary fire, which is ordinary firewood, and the other is iron fire, which contains iron. Ores, etc., the third type is the sacred fire... This sacred fire comes from a log refined by a special method, which is extremely expensive, and sometimes even hundreds of times more expensive than the top pill... Therefore, this sacred fire is extremely difficult to find, and it is mostly used in the refining of holy pill...Master Hao, am I right?!"

"Wrong...it's right, it's just not enough!! Who else knows?!" Hao Shan's eyes turned to everyone.

Sheng Yun hesitated for a moment, then raised his hand: "Master Hao..."

"For you..."

She trembled and stood up embarrassedly: "I... I also heard my grandma say that there is a kind of fire in the legend, which comes from the land of no illusion, called Burning Heaven and Industry Fire... This kind of fire will last for a long time. , You can refine pill of any quality... It's just that this kind of fire has been extinguished, and I am afraid it will be difficult for the entire Protoss to find..."

Master Hao nodded approvingly, and finally showed some smiles on his face: "Yes! It seems that among you, there are people who really know what to do... Our Yaoshan Sect used to burn the heavens to refine alchemy before, only for three thousand years. Earlier, the flame of the Burning Sky Industry was extinguished, and there has been no such fire..."

Fingertips moved slightly, he suddenly raised his hand, and a cluster of flames jumped out of his fingertips.

"Do you know what this is?!"

All the pill girls were dumb, but Ling Luoyu slowly raised his hands: "No fire!!"

No fire, the best fire of alchemy fire.

It is the fire that a person who cultivates alchemy produces. Depending on the method of cultivation, the fire produced is also different.
