Chu Yuan transmigrates to the borderlands of the Great Shang dynasty and becomes a low-ranking gate guard.
The Investiture of the Gods is about to begin, and the gods and Buddhas in the heavens regard humanity as no more than ants.
Fortunately, he awakens a Check-In System and obtains the conceptual treasure Spy-Detecting Compass from the start.
As long as he is within Great Shang territory and his opponent is a spy, no matter how powerful they are, he can forcibly bring them down to his own level!
And so Chu Yuan becomes Great Shang's most ruthless man, hunting down spies from beyond its borders without pause.
The Chan Sect's deputy leader, Ran Deng, sneaks in disguised as a charcoal seller, only to be felled with one slash and tied up like a bundle.
A celestial general from Xiqi launches a nighttime prison break, only to be beaten into a whimpering wreck with a flurry of blows.
Then the Twelve Golden Immortals arrive together, intent on reducing the borderlands to scorched earth.
Chu Yuan silently takes out his compass. Watching the immortals' cultivation plummet to the Qi Refining stage, he breaks into a benevolent smile.
"It's already the hour of the Rooster. I'm off work. You lot of immortals ready to get beaten?"
