The missing elf

嗡--嗡--嗡--

The periodic vibrations came from under the pillow, and the music was getting stronger.

Zhang Zian woke up in a daze. He felt that he had just closed his eyes and hadn't fallen asleep at all when his phone alarm rang.

Why did the phone alarm ring?

He had just left the dream, so his mind was still at the border between reality and the dream, and he was not completely awake.

It was still completely dark outside the curtains, with the occasional raindrops hitting the window glass.

It was time to get up and pour water.

He finally remembered the reason for setting the alarm. The typhoon had just passed, and the sewage outside had not subsided.

If the sewage that seeped through the door gap was not cleared every two or three hours, the first floor might be soaked. When the sewage reached the height of the kick line, it would leave an ugly watermark on the wall that would be difficult to remove unless the wall was repainted.
