Lin Siyu, a fashion designer in the 21st century, traveled back in time to a little bitter melon from the 1980s with the same name because of a dagger. After time travel, she followed the philosophy of "I won't offend anyone if they don't offend me, and I will punish them if they offend me."
Then she used the "gift" given to her by her son in another time and space to start the "money-making" mode and lead the family to get rich together.
A family of three who originally lived in three different time and spaces, due to the butterfly effect caused by their son's quantum research results, eventually became a family of four, living happily together in the same time and space.
