Gambling?

The young man's name was Touan Xiaole, and he was looking at Yuchi with a kind expression.

Yuchi and Yue Hanjiang looked at each other. Then, Yuchi took the initiative to ask the young man, "I've come to this place to learn alchemy. Could Little Brother tell me some things about alchemy."

Cofuran had been busy with some things recently.

Thus, after talking briefly with Yuchi about the matters of the Alchemist Valley, she had returned to her own affairs.

Obviously, she was so busy that she did not even have the time to explain the basics to Yuchi. 

Incidentally, Yuchi had also asked her what exactly she was doing. However, she did not tell Yuchi the details and only said that it would not be harmful for him. 

Since that was the case, Yuchi and Hanjiang were left to their own devices to explore the Alchemist Valley. Since this young man had come along, perhaps they would be able to learn a thing or two from him.
