On the eve of the Songhu Battle, Shen Hengzhi woke up again. In his last life, he killed an entire underground team because of a piece of late intelligence. In this life, he took his prophetic memory and sat in the Translation and Telecommunications Department of the Nanjing National Government. The Higashishima Sakura Agency offers a reward of one million for the life of "Lin Yuan" - and "Lin Yuan" is his other identity. Eisuke Kawada handed over a new set of code books and asked him to decipher it within three days. Shen Hengzhi glanced at it and saw that it was the secret combat order that the Dongdao Navy was about to use to launch a sneak attack on the Minjiang River Estuary. He only had to change three numbers in the translation to have the fleet crash into the Guangxi army's fort. But troubles ensued: the military inspection team parachuted into the Translation and Telecommunications Section to investigate the mole; the new liaison officer of the underground party turned out to be the sister of the comrade he killed in his previous life; and the most dangerous thing was that Eisuke Kawada began to test the loyalty of "Lin Yuan" - asking him to hand-deliver a false intelligence to trap the core of the Huazhou underground party. If you hand it over, your comrade will sacrifice; if you don't hand it over, your identity will be exposed. Shen Hengzhi held the pencil tightly and wrote the third answer in the blank space of the codebook.
