Fu Qing traveled through time and became a dog-licking son-in-law. In order to marry into the Li family, he awakened the "demon making system". The harder he acted, the greater the reward. On the day of the wedding, Fu Qing turned against her and demanded an 880,000 yuan exit gift and 18 gold jewelry in public. If he didn't give it, he would jump off the building, causing the wealthy Li family to lose face. Li Wenwen was furious on the spot but helpless. After the marriage, Fu Qing relied on his peerless medical skills and extreme devilishness to dominate the Li family. Li Wenwen also gradually changed her view of Fu Qing in repeated confrontations and pursued him head-on.
