Ren Yi smiled and said: "Master Zhang, please check it again. If there are any problems, I can replace it again."

Zhang Yu checked and found that the quantity was much more than the medicinal materials he wanted to buy, but the quality was somewhat uneven. However, considering that the requirements for ordinary medicine and his elixir refining were different, it was impossible for outsiders to know this place.

This is also acceptable.

Um?

While inspecting a certain medicinal material, he suddenly felt something strange. He pinched it with two fingers, picked it up and looked at it. It was a bone fragment as big as a fingernail. To his surprise, there was an extremely faint trace of something on it.

The source energy exists, but it's so weak that he can hardly detect it if he doesn't pay attention.

He looked at Ren Yi and asked: "Where were these bone fragments purchased?"

Ren Yi looked over, took out a worn-out book, flipped through it, and said, "It's from a small business called Futong. Is it possible that Assistant Professor Zhang is not satisfied? Then you can change it again."

Zhang Yu put the bone fragment down. There was too little source energy on it. Even through gloves, he could absorb it in just one breath. He said, "Please let me help you make another trip for me. Please try to get as many medicinal materials as possible."

Buy some, I'll use them, you don't have to worry about the price."

Ren Yi said with a smile: "What the hell, Assistant Professor Zhang is willing to take care of our business. It's not too late for me to be happy. I will go there myself tomorrow."

At this moment, heavy footsteps came from outside, and the honest man named Lao Yang walked in with tea in one hand.

Ren Yi was dissatisfied and said: "Old Yang, why are you so slow?"

Lao Yang lowered his head and said nothing.

Ren Yi looked like he hated the iron, he stepped forward to take the tea cup, waved his hand as if to drive him away, and said: "Forget it, forget it, you can go down."

When Lao Yang was about to go down, a voice came from behind:

"Wait a moment."

Lao Yang's body froze.

Zhang Yu looked at him and said in a very casual and natural tone: "What's wrong with your right hand? Can you give me a look?"
