Detective Chen Mo traveled to a war-torn era and unexpectedly awakened the ability of "Xinjian" - he can see through people's inner positions at a glance: black is the enemy, red is the comrade-in-arms, and gray is the ordinary person who is swaying.
He is as timid as a mouse, but he is forced to use these "clairvoyance eyes" to deal with Japanese spies, military commanders, and traitors. He sneaked into the concession by seducing Japanese girls, used the priest's swinging position to gather information, and even forced top spies to reveal their feet...
No one knows that this "rat" who is always hiding in the corner is using the most cowardly posture to quietly reverse the direction of secret wars one after another. And deep in the hearts of those he "saw", there are struggles and courage that are more complicated than war.
