A Mysterious Metal Box
The sudden increase in volume startled everyone in the room. Although they were puzzled, Xia Weiguo immediately stopped his actions. "Do you know what's inside this?" he asked.
"I don't know, but the color of this box looks like aluminum," Su Yijia replied with a slightly serious expression.
Xia Weiguo carefully examined it and confirmed, "It does seem to be aluminum."
Seeing the young girl reach out her hand, he didn't think too much and directly placed the small box in her hand. The weight and the feeling of being unable to squeeze it made her realize that the small box was quite thick, and whatever was inside was probably the size of a fingernail.
"What exactly is inside this?" Xia Weiguo noticed that her expression was becoming more serious, and his attitude became even more cautious and serious.
