Ghost Knocking at the Door in the Dead of Night

December 30, 2024, 9:30 p.m.

Knock, knock, knock! Knock, knock, knock!

In the dimly lit room, Su Bai was typing with intense concentration when he suddenly heard a series of knocks at the door.

"Who is it?" Su Bai stood up and called out, puzzled.

"Su Bai, open the door!" His mother's somewhat weathered voice came from outside.

Su Bai walked over and took hold of the doorknob. Just as he was about to open the door, he froze. His parents were long-haul truck drivers who worked as a team. Normally, they wouldn't be home until two in the morning.
