On the night after the college entrance examination, Lin Mo was still a weakling blocked by the school bully in the alley.
It wasn't until he accompanied Su Xiao into the Forbidden Mountain and watched her being dragged towards the altar by the shadows that he understood what his grandfather said - the rusty bronze knife was a sharp weapon for killing ghosts; the Yin-Yang fish birthmark on his wrist was the key to traveling between the two worlds.
"Your parents died following the rules. Now it's your turn to break the rules."
During the day, he is a prospective college student with an admission letter;
At night, he wields a knife and goes through the yin and yang, pleads for the life of the wronged soul, and challenges the judge of the underworld.
From being a coward who could be manipulated by others to being a ruthless person who smoothed the injustice between the two worlds, it only took one summer vacation.
After all, the college entrance examination can change one's life, so why can't it follow the rules of the Yin and Yang world?
