Espionage: Are You Crazy? You Call That Violent Man an Agent?

After transmigrating to the Central Army Academy in Jinling in 1936, Chu Lingyun faced a dead end: a powerful man's son was forcing him to give up his spot, so he could be sent to the border as cannon fodder.

Chu Lingyun refused to back down. He grabbed an iron frame and smashed the young thug's arm, awakening the [Brute Counterintelligence System]!

As long as he shattered enemy agents' resolve and dealt a heavy blow to hostile forces, he could obtain top-secret intelligence and physical attributes with a 100% success rate!

When the Military Intelligence Department heard what happened, they not only let him off, but treated him like a treasure. "That kid doesn't hold back. He's the sharpest blade the Republic has!"

From that day on, Jinling lost a mild-mannered cadet and gained a human demon king who made enemy agents tremble at the sound of his name!

A Japanese ace agent stubbornly refuses to talk? Chu Lingyun spends three minutes in the interrogation room, and the agent breaks down, revealing the entire network of infiltrators.

A military insider thinks his high rank puts him beyond reach? Chu Lingyun draws his gun, presses it to the man's head, and tears out the entire rotten network, confiscating everything.

Enemy puppet officials plot an assassination? Ten shots through the same hole, fired blind, and one man pins down an entire stronghold!

Director Dai: "I always trust Lingyun to get the job done. Having him is a blessing for the Republic!"

Japanese puppet regime's Special Higher Police: "Pull back! That lunatic in the black trench coat is checking our records again!"

Years later, with the war's outcome settled, people saw German artillery and vast quantities of medicine streaming toward the front lines in northern Shaanxi and finally realized the truth:

The Kuomintang's most ruthless secret police officer, who ruled the streets by day, was secretly the greatest contributor to the Communist war effort?!
