Me! The Number One Foolish Traitor, Actually the Ultimate Undercover Agent

[Resistance-war espionage + play the pig to eat the tiger + misunderstandings + double-agent infiltration + deep-cover spy + no abuse of the protagonist + long-form]

The whole city curses Cao Liwen as a greedy, stupid traitor, yet the Japanese and the KMT’s secret service compete to promote and recruit him! Everyone laughs at him for being a brainless time-server. Little do they know that he has spent decades playing the fool while undercover, operating from Jiangcheng to the isolated island. He is the ultimate deep-cover agent, with not a single flaw.
