It was a small box made of maple wood, and it was in Xue Mingyu's palm. Its size was even smaller than the King's palm, and Yu Ming confusedly focused his gaze on it.
"What's that?" As he shifted his gaze to Xue Mingyu's eyes, Yu Ming asked that question.
"You can open it, Master Yu," instead of answering, Xue Mingyu gave an order.
How Xue Mingyu ordered him instead of answering his questions was enough to irritate Yu Ming. A frown appeared on his forehead as he continued to stare at the Demon King, and he was probably trying to restrain himself from cursing the King.
In the end, Yu Ming managed to control his mouth, and he quietly took the box from the King's palm before opening it. As soon as the box was opened, the wrinkles on his forehead deepened.
"A fish scale?" Confused, Yu Ming asked the question while once again fixing his gaze on the Demon King.
