In the wealthy town of Jiangzhou, there is an inconspicuous inn at the end of the alley, named "Nan Ke Meng". The proprietress A Ke is unknown where she came from and her identity is unknown. She looks proud and beautiful, but her personality is very strange. Her moods are unpredictable, and it is common for her to lose her temper in front of guests. But despite this, the inn's business is still booming, and there is an endless queue of people queuing to stay, because everyone is surprised to find that as long as they fall asleep here, the troubles lingering in their hearts will miraculously disappear when they wake up, and they will sleep soundly from then on. "Book of the Later Han Dynasty" records: "Xiong Bo eats ghosts, Teng Jian eats bad luck, Lan Zhu eats troubles, and Bo Qi eats dreams." The Bo Qi tribe is endowed with divine power, immortal, stationed in one place, and is responsible for eliminating troubles for the people who stay there, and makes a living by eating nightmares. And the proprietress A Ke of "Nan Ke Meng" is their descendant. Compared with other tribesmen who fulfilled their obligations conscientiously, Ake was full of complaints about this job at first. She couldn't understand why the Birch tribe had to eat those strange and dark nightmares in order to survive. But as time passed and years passed, Ake met many people, including a deaf-mute child, an old man with a long-term illness, a desperate woman who couldn't get the love she wanted, and an iron-blooded general who fought on the battlefield... Without exception, they would cry in their "Nan Ke Dream" and leave behind their troubles about this world. Ake observed the mixed feelings of the world in the dreams of these people, and gradually learned many things that she didn't understand before...
