Shen Ye, the number one killer in ancient times, was betrayed by his best friend and died from random arrows. When he opened his eyes again, he became Lin Mo, a good-for-nothing college student who was bullied by the whole school.
The ballpoint pen is an acupoint killer in his hand, and ancient intelligence techniques make modern criminals fearful. Starting from three streets in a village in the city, he used the brains of a thousand-year-old killer to carve out a niche for himself. Brothers, rivals, an old enemy that has lived for a thousand years - this revenge that spans a thousand years has just begun.
In his new life, he will no longer be a killing knife, he will be the one who holds the knife.
