Yu Qingqian and the two rode their horses all the way for two days before they reached the mountain where the stamens were hidden.

  The mountain looks a bit desolate, with some scattered vegetation covered, and some places are bare, and the road is relatively rough.

  Che Tongtong said with some disgust: "There are quite a few wonderful tasks in the Holy Court."

   "The stamens of the demon plant can be used to extract high-level potions. It should be promulgated by a potion master elder in the courtyard." Yu Qingqian didn't care about such an environment.

  Che Tongtong shrugged, "I don't have the talent for potions. It would be interesting to think about refining potions."

   "Well, refining potions is very interesting." Yu Qing said with a smile: "Especially when researching formulas by myself, it is not only interesting but also a sense of accomplishment."

  Yu Qingqian and Che Tongtong are now familiar with each other, and both of them are relatively straightforward, and they don't like to be around the corner when they talk.

Che Tongtong's eyes lit up, looked at Yu Qingqian and asked, "Is there any medicine that can be used to treat people? For example, those that spill out hot eyes, those that make people's whole body soft and immobile, or those that make people speechless and become dumb for a period of time. wait."

   "..." Yu Qingqian couldn't help twitching the corners of her mouth when she heard her words, no wonder Che Tongtong was called a little witch.

   "Those you mentioned should be the medicinal powders used by mortals."

  Che Tongtong nodded: "Yes! I have collected a lot of them before, but it is still effective for those with spiritual cultivation, but it is useless for spiritual planters above the spiritual level."

   "We are good friends." Then she pulled Yu Qingqian's sleeve and pretended to be pitiful.

  Yu Qingqian knew what she meant: "The medicinal materials used in the medicinal powder have no spirituality, and naturally they are not of much use to the spiritual planter. If you really want it, I will try to extract it after I go back."

   After hearing what Che Tongtong said, Yu Qingqian also thought that those potions should be quite interesting.

   "You're such a good friend." Che Tongtong smiled with bright eyes.

  The mountain road is not easy to walk, so the two of them went up on foot.

   Gu Yan in the small tower naturally heard their conversation and smiled and said, "Xiao Qingqing, you are a good friend."

"Master, what you said is good mainly refers to her proposal." Yu Qingqian rolled his eyes in his heart, Master Shifu is also a fear of chaos in the world, no wonder he was suppressed in the small tower, and I don't know before What have you done.

Gu Yan laughed: "It's true, I once saw a pharmacist with a weird temper. He would extract some strange potions and feed them to his spiritual plant, and then the spiritual plant would have it. A lot of very special effects."

   "I think you can give it a try, extract some potions to feed on Yaozhi, and just use that little girl's idea. In the future, it will definitely be beneficial to the enemy."

   He added a little excitedly: "Although I am not a master in medicine, I can provide you with advice."

   Yu Qingqian was also interested when she heard it. Originally, she was going to extract some poison to fight back against those who wanted to deal with her. Now, if she feeds Yaozhi, the effect will become long-term, and it will definitely kill people and make people invisible.

   "Okay, I'll study and refine it when I return to the academy." Yu Qingqian was even more concerned about the Venom Tome.

  Gu Yan tasted the wine brought in by Yu Qingqian and was very satisfied with the tacit understanding between his apprentice and himself.

   "Huh!" Suddenly his expression turned upright, his mind reached out further, and then he reminded: "Girl, the fish you caught has been hooked, but this time it is estimated that you have gone too far."
