In this world, rules are alive and principles are dead. Only those who are dead can be impartial.
Ning Shou is a young man who only knows how to carve monuments. His belief is very simple: you must do what you promise.
It wasn't until he walked out of the muddy alley that he discovered that scholars, monks, and sword immortals each had their own way of living and their own rules. Whoever has the loudest voice and the sharpest sword is the right one.
All he wanted to keep was a promise he made to the girl next door, a dull old carving knife left behind by his master, and the deadlock in his heart that nails are nails and rivets are rivets.
Jianghu is a network. Some people walked in the net in a polite manner, while others wanted to poke a hole in the sky with a useless blunt sword.
This is the story of a young man who accepts death and asks himself and the world about "the truth".
