Emotion is power, but also price.
Decades ago, an "emotional storm" swept the world. When a person's emotions are so strong that the soul cannot bear it, the emotions will break away from the body and manifest into a unique supernormal power - the mind.
Some say it is a gift of evolution, others say it is the seed of destruction. In Shuangting, the capital city of Yunshuo, emotion itself is something that needs to be controlled, treated, and smoothed out.
Silence leads her sister Shen Yan, who can only hum the same melody over and over again, to live quietly in this city where sound is not welcome. He has long since learned not to expect, not to be angry, not to be unhappy.
Until Ana Shen disappeared and was found by him again. Until he saw his sister being involved in a secret plan called "Lullaby". Until he touched the door for the first time.
"Void Boat" awakens.
Touch the door and he becomes the door. By touching the knife, he becomes the knife. Each time he uses it, he loses a random emotion. Anger, sadness, fear, joy, even love.
"You are empty to begin with, so you can hold anything." The man in white gloves said gently.
But when you sail on the water with an empty boat, you will eventually know your own weight.
This is a story about how emotions are suppressed, plundered, and rediscovered.
There is no absolute good or evil, no perfect ending. Some are just a few young people desperately trying to hear each other's voices in a silent era.
