There Is a World Inside the Glass Box

He Yu bought a strange glass box. There was a mini world of cultivation inside the glass box, and the villains inside were beating around all day long. The leftover lobster claws were thrown into the box and became the remains of the big monster that stirred up trouble. The button battery he threw into the box became an endless source of thunder. He even threw the small plastic glowing sword he played with as a child into it and it became a magic weapon that sealed the earth.
