Jiangcheng Dream Seam

Everyone who falls asleep will go to the same city, but no one can remember what they dreamed about when they wake up. Home inspector Chen Zhu is different - he inspects homes during the day and dreams at night, looking for things for people, delivering letters, and waking up people trapped in nightmares. He could also see something that others couldn't see: the city was made up of pieces, and the cracks of the pieces were all over the city. Grandpa died of an "unexplained coma", and the measurement notes he left behind contained a line of red writing - The key is people.
