Sister Lin Helped Me Take the Imperial Examination, and I Helped Her Strengthen Her Body.

A migrant worker who died suddenly while working overtime transformed into a non-existent character in the Dream of Red Mansions - the emperor's grandson and the number one dandy in the capital. As soon as he opened his eyes, he met the sick and frail sister Lin who was living under someone else's roof. Due to an accident, the two exchange souls every three days. On the first day he became Sister Lin, he threw the bowl of poisonous medicine, which shocked the servant who sent the palace flowers to the point of autistic disorder, and made his hypocritical cousin Jia Baoyu break his guard on the spot. The first day she became him, she wrote a policy essay in school to become a god, slapping the faces of her classmates who looked down upon him. Later—— He helped her "kill" her crazy in the Grand View Garden: uncovering the real culprit of the poison, tearing up the Green Tea Sisters with his hands, and making all those who bullied her kneel down and call them daddy. She helped him win the imperial examinations: he was able to win the title of Yuan in the provincial examination, he was tested by the palace, and he counterattacked from a loser to a new noble in the court. Everyone wants to see their jokes. In the end, they became each other's only salvation.
