Chenfan, a college student from the 21st century, woke up and traveled to the war-torn Five Dynasties and Ten Kingdoms, becoming a powerless "scholar" in the world of "The Bad Man". Amidst the flames of the ruined city of Chang'an, he was rescued by a bad person by accident and was bound to an unreliable "survival system".
With a foresight of the plot, but no force at his side, Chen Fan can only learn to survive in troubled times: practicing swordsmanship with Shangguan Yunque, asking Lao Xu for advice on the world, protecting the people from fleeing under the claws of the zombies, using modern knowledge to bandage the wounded, sharing chocolates with children...
He has seen the passion and responsibility of bad people, and also experienced the struggle and tenacity of people in troubled times. When the shadow of the Xuanming Sect gradually enveloped Chang'an, and when the legendary Corpse Ancestors quietly appeared, this intruder from a thousand years later, holding a bad guy's short sword, suddenly understood: The so-called bravery never means not being afraid, but knowing that you are trembling with fear, and you will also raise your sword for the people behind you.
This is the story of an ordinary social animal in a world of bad people, who goes from "just wanting to live" to "wanting to live protecting more people." There are the relaxed daily routines of making jokes, the moments of life and death with swords and swords, and the warm warmth of people supporting each other in troubled times - after all, no matter how dark the night is, someone has to guard that light and wait for the dawn.
