Welcome to the Puzzle World

Lu Qingsong suffered a shock and developed a rare condition called delayed emotional response.

To treat it, he followed his doctor's advice and began trying all kinds of ways to stir up his emotions.

Roller coasters, haunted houses, horror stories, adventure games...

Then one day, he received a jigsaw puzzle with a bizarre image on it.

The background was black, with a bright red fingerprint printed on it.

The image was somewhat faded, as if someone had held it in their hand and rubbed it over and over.

On the back of the puzzle was a line of small writing: Welcome to the Puzzle World.

That night, just as Lu Qingsong was about to change into his pajamas and go to bed, he found himself at a highway entrance, where six people were waiting for him to get in their car.

They told him the puzzle was his ticket home...
