Gu Chuan, a middle-level member of a large Internet company, died suddenly after working overtime and transformed into a triple agent in 1944 - "Dawn" sent to Japan by Yan'an. At the same time, he was deployed by Japan to join the military. He also carries with him his system and his suburban townhouse in Hangzhou, which still has a 30-year loan that has not yet been repaid.
The three parties received a secret order at the same time that "there is a ghost inside", and the ghost to be investigated happened to be himself. The Japanese suspected him, the military commander kept an eye on him, and Yan'an told him to "hold still and don't move." While dealing with the hunt, Gu Chuan used modern supplies in the villa to make trouble: antibiotic powder was used as a secret recipe handed down from his ancestors, a power bank powered the Republic of China radio station, and instant noodle seasoning packets were passed off as Western spices.
When the three parties' guns were aimed at him at the same time, Gu Chuan charged up his mobile phone and opened "The Legend of Zhen Huan" - learning about palace fighting while waiting for dawn.
