This is the age of the dark forest where spiritual energy is revived and the weak eat the strong. Lu Zhan was betrayed by his best friend and fiancée, and his martial arts were shattered. When he was about to die, he bound the mysterious [Final Killing Engine] - killing to make him infinitely stronger.
From then on, there was an additional "Shura" in the shadow of the city. He hunted evil, devoured powerful enemies, and fought bloody battles between ancient martial arts families and extraordinary organizations. It wasn't until he met Su Yeli, the cold genius executive of Longyuan Pavilion, that he discovered that his killing power was actually the only tranquilizer for the ancient dragon soul in her body.
The two started from a transaction of mutual use, and gradually became each other's only anchor point and sharp edge in the dark forest. When the supreme civilizations behind the battlefields and systems hidden behind the scenes emerge one by one, the final choice Lu Zhan faces is: to become the final messenger of destruction, or to rewrite the rules and light the first bonfire of civilization for this cruel forest.
