Lu Queyi has known one thing since he was a child - he can see what is missing in others.
The son of the blacksmith next door was born without a phalange and could not practice swords. He climbed three mountains to find a dead iron-bone pine, dug out a piece of root and connected it to the boy. The boy later became the youngest swordsmith of the Xuantian Sect.
The widow who sells tofu at the end of the street sheds tears every day. What she lacks is a piece of her husband's old clothes that was washed away by the water. Lu Queyi searched for it on the river beach ten miles away for three days and three nights. The widow reopened the tofu stall the next day.
Everyone said he was a good Samaritan. But no one remembers what he looked like.
His face will always be blurry in the eyes of others, his voice will be forgotten once heard, and the residual warmth of the stool he sat on will immediately dissipate. He lives in this world, like a puddle of water slowly evaporating in the sun. He doesn't even know what he lacks - he sees everything but himself.
Until one day, his [Missing Eye] lit up in front of himself for the first time.
That day he was washing clothes by the river, and his own face was reflected in the water - he saw that the face was missing a nose, eyes, and mouth. Nothing, blank. And in the middle of that blank space, there was a crack that was slowly widening. Deep in the crack, something is crawling out.
For the first time he became afraid. Because he finally knew - he was not born a complete person. He is the "missing piece" in other people's destiny, torn apart alone and left to wander in the world.
