CompletedSu Yu travels to a parallel world and becomes a sixth‑grade elementary school student, initially chosen as a target for a safety education publicity program.
He originally thought it would be a simple children’s educational initiative,
but when a prank system is triggered, the tone quickly devolves.
During a test where a police officer poses as a delivery person,
"Hello, I’m the delivery person. May I come in and have a drink of water?"
"Sure thing."
Police: "Have you ever considered that I’m a villain?"
Su Yu: "Oh, have you considered that this cup of water was scooped from the toilet?"
"Guffaw!"
Police: "Are you not afraid?"
Su Yu: "I was scared at first, but now I’m not."
"Why?"
"Because the water is drugged!"
