Shen Qingyue, an urban white-collar woman who traveled back in time to 1975, unexpectedly became a vicious fake daughter in a period novel. The original owner was despised by his adoptive parents because his true identity was exposed, was set up by the real daughter, and eventually died tragically in a foreign country. Shen Qingyue relied on the "time and space clock-in and sign-in system" that was accidentally activated to start a counterattack in the 1970s when supplies were scarce. By signing in every day to obtain various skill experience cards, material rewards and special abilities, she gradually grew from a fake daughter despised by everyone to an archaeological restoration expert and private entrepreneur favored by the group. In the process, she also gained a love with Zhou Shiyu, the ascetic scientific research tycoon.
