Archie opened the bag he had brought, revealing a square brown box.
Huanhuan walked around the box and didn't think there was anything magical about it. It was just an ordinary wooden box. She asked curiously, "What's in it?"
Archie didn't keep her in suspense. He opened the box on the spot and revealed its contents.
The box didn't look big, but it was filled with a lot of things. They looked strange and useless.
Huanhuan casually took out a metal mouse and asked with interest, "What is this? It looks quite interesting."
"It's a tracking mouse. I invented it last year. It can be used to track targets. It's very fast."
Under Archie's guidance, Huanhuan winded up the little mouse, then twisted its tail and lowered it to the ground. Its eyes darted around and it began to spin in place.
Archie said, "You need to give it a sniff of the target before it can find it."
