The door-to-door son-in-law Lin Kun is a "wimp" who is always frustrated at his wife's house. His only hobby is tinkering with various home appliances. However, an unexpected lightning strike caused his brain to be invaded by a mysterious "knowledge database". Overnight, he changed from an ordinary person who could not even connect the circuit to a "walking encyclopedia" who knew both astronomy and geography.
His sudden "superpower" made him famous overnight, solved countless scientific problems, and also involved him in conspiracies and crises related to the safety of the world. He became the all-powerful "Master Lin" in the eyes of everyone, and he was surrounded by seven extraordinary women with unique skills and different personalities. They either worshiped him, relied on him, or fought alongside him, and together they composed a series of thrilling legends.
However, when the world was saved and the crisis was resolved, Lin Kun discovered that this powerful knowledge was more like an inescapable curse. He can easily calculate the origin of the universe, but he doesn't know why his wife is angry; he can repair the most sophisticated instruments, but he can't repair the increasingly estranged relationship with his family.
It wasn't until he finally lost all his superpowers and turned back into the ordinary old man who could fix a broken rice cooker and forget formulas that he suddenly realized: the real "power" is not to have the power to change the world, but to have the warmth to protect ordinary life.
