章 677: Chapter 677: The Focus of Yang Wenxiao

Once they entered the hall and seated themselves, Yang Ye picked up a sweet potato strip with his chopsticks. He tore off a small piece and put it in his mouth, then placed the rest on the plate in front of Yang Wenxiao.

This was a poison test.

Yang Wenxiao picked up the slightly shortened dried sweet potato with his chopsticks and put it in his mouth. He nodded afterwards, satisfied with the taste.

"Not bad. How is this made?"

In the past, people also made dried sweet potatoes, but they simply sliced the sweet potatoes and let them dry out. The dried sweet potato strips, having lost their water content, could be preserved for a long time.

"Er...I didn't ask," Yang Ye shook his head.

Confronted with this sight, he had only been wondering how to change the color of the dried sweet potatoes. As for the method, he hadn't thought of it at all.

"Ask about it, and pass it on to your brother Xiaohao," said Yang Wenxiao.
