Jiang Feng transmigrates headfirst into the world of Drawing Sword and becomes the political commissar of the Independent Regiment. Before they can even take down a Japanese blockhouse, he stumbles upon a shocking case: a mole, codenamed Yan-03, is hiding among the senior leadership in Yan’an and continuously feeding the Eighth Route Army’s intelligence to the Japanese.
From Heifeng Pass to Beiping, from the Baoding power station to the depths of Yaozi Ravine, Jiang Feng uses modern engineering and criminal psychology to peel away disguises, crack codes, and infiltrate the enemy in turn. But only at the very end of the fight does he discover that Yan-03 is no traitor. They have spent four years laying the pieces for a game that spans time.
The lives of six combat engineers, three transmission routes, and a secret capable of rewriting the history of the War of Resistance. When the Zero Day coordinates lock onto July 6, 1937, Jiang Feng must choose between going home and defending the city. And the person behind it all is waiting for him at the doorframe.
