A "mistake" by the creator Yuan started a pursuit that shook the three worlds.
The puppet girl Zhiyao, who was created and exiled by the gods himself, woke up from the silence, her chest was empty, except for a gentle instruction to find her "heart". She doesn't understand the world, but she is destined to find the meaning of her existence in this world of joys and sorrows.
Yun Yi, the ruthless Taoist who came under the command of Heaven, should kill countless people with his sword. But when he faced that "mistake" who was as ethereal as glass and who worked harder to learn to smile than to kill, cracks appeared in his cold Taoist heart for the first time. Surveillance turned into companionship, judgment turned into guarding, and the path under his feet was leading to irreversible rebellion.
Along the way, they gathered together partners who bear fate: Chi Yan, the guardian who hides the pain with heroism; Su Yi, the doctor who heals the scars with gentleness; Mo Yuan, the guide who guides the way in the fog.
In this journey to find the scattered love threads of gods, anger, sadness, joy... All kinds of human tastes are embedded in Zhiyao's empty chest like fragments. She learned to feel, to feel pain, and to love. Yun Yi, on the other hand, was torn between reason and emotion, step by step from the executor of heaven to her own patron saint.
When they finally pieced together the truth that had been silent for eternity - that cruelty of "heart-breaking" was actually the most desperate tenderness that God could win for her between rules and personal relationships - there was no turning back.
The law of heaven does not tolerate personal relationships, and the sword hanging high has fallen.
Should he obey the rules and die, or should he fight against fate itself for the love in his heart?
"If it is wrong to protect you, I will fight against the whole world for you."
Intention: The collision of rules and emotions, the ultimate pursuit of individual existence value.
