Hearing Yu Ruyi's question, Demon Yun smiled and said, "Teacher, the taste of the skin of the dragon fruit is a little different from that of the dragon fruit!" Demon Yun knew that he couldn't see anything on the surface, so he suddenly thought of what Yu Ruyi had mentioned when he was explaining the two fruits to himself.

"The difference between dragon fruit and dragon fruit is their flowers, and the root of dragon fruit has bitter stamen!" Yu Ruyi said at the time.

At first, Demon Yun didn't know what the connection between having a bitter stamen and distinguishing the Earth Dragon Fruit from the Heavenly Dragon Fruit was, but now she knew! It turns out that this is the way to distinguish between dragon fruit and dragon fruit.

"Oh!?" Yu Ruyi was a little surprised, although she said it at the time, but this girl was able to think of it so quickly! It's not easy!

In fact, ordinary medicinal materials can be distinguished from appearance, so ordinary alchemists have also walked into a misunderstanding, only using appearance to distinguish medicinal materials, so it will cause those so-called indistinguishable. As long as you can think in a different direction! It is not so difficult to distinguish the medicinal herbs.

"Teacher, am I right?" Demon Yun stood up, she was very confident in her memory, because of her spiritual attributes, it can be said that she is basically unforgettable!

"That's right! This is indeed the difference between dragon fruit and earth dragon fruit! Yu Ruyi looked at the demon cloud, and the serious flames became more and more hot!

This precious apprentice of his own may really be able to reach that legendary level in the future! The level that I haven't reached after working hard all my life! The supreme honor of the alchemist!

"You've finished learning the knowledge of pharmacology, Yun'er, next to the opening of the academy, you don't have to come to me every day! Just come every other day! I'll give your homeroom teacher a shout-out! Yu Ruyi looked at the girl in front of her, her eyes full of relief.

In the past two months, I have seen with my own eyes how she has cultivated, from a second-order intermediate psychic master, to a first-order high-level psychic master. Although Demon Yun has been here for the past two months, he has never used a single pill! It's all by her own efforts!

The energy of the elixir is not your own after all! If you use too many pills, it will cause more and more difficult cultivation in the future, but! This kind of concentration that is not used to guard so many pills is not something that an ordinary fourteen-year-old girl can have! This is also one of the places where Yu Ruyu is most satisfied with her apprentices!

"That's it! You have a day off today! Tomorrow Tianji will start school! After Yu Ruyi finished speaking, he took out a set of school uniforms, school emblems and an identity tag from the space ring, and handed them to Demon Yun.

Demon Cloud took it and put it into his spatial ring!

That's right, she has already recognized this space ring, and her mother's body is in her bracelet, and it wouldn't be good if she put some miscellaneous items in it! So, this ring is just right!

In the past two months, Ye Xuan has been dead for a long time, but he just stayed for one night every day and left in a hurry!

The most hateful thing is that you won't talk about it for one night! I have to squeeze in a bed with myself! Kick and can't kick, his strength is stronger than himself! I had no choice but to swallow my anger and let him go!

"I've already taken care of your admission, and you don't have to crowd the space with those people every day! You can play comfortably for a day, and by the way, you can also take a stroll in this Polar City! You haven't been out in two months! "Yu Ruyi is full of praise for his apprentice's patience! For Ye Xuan to find such a good apprentice for himself, naturally he didn't give him any benefits!

Of course, this benefit is an agreement between two people, and Demon Yun naturally won't know about it!
