Novel Blurb: Wang Mulin, male, thirty-two years old, graduated from a 985 university, works as a math teacher, and is an unmarried man in his thirties!
He's got enough to eat on his own and no family to feed. Aside from his parents constantly nagging him about marriage, Wang Mulin is quite happy with his life.
But maybe after being single for too long, even drinking cold water makes you choke. One day after work, Wang Mulin passes a reservoir and dies young while trying to save two children from drowning.
Then he transmigrates, becoming a widowed man in ancient times. All he has at home is a dog, two children, three mu of land, and four chickens. He's practically penniless.
After finally discovering that he brought a System with him, he finds out it's an old-person version of a farming System. It can only check the weather and pull weeds, and even making it rain requires saving up points. With no other choice, Wang Mulin takes the two children and works hard to farm and make a fortune in ancient times.
Theme: An optimistic life is the greatest wealth.
