Bai Sui Kai Xitong, Xiaozi Xiansun Gui Man Shan!

Xiao Chen is a transmigrator who has lived a long, quiet life in his new world. For nearly a century, he experienced the ordinary passage of time without any extraordinary advantages, eventually reaching the age of one hundred. Now lying on his deathbed with his final moments approaching, his existence takes an unexpected turn when a mysterious System finally activates after a lifetime of silence. This newly awakened System offers him a remarkable path to survival and power. By ensuring that his descendants have children of their own, Xiao Chen can earn valuable rewards. Each new addition to his family line not only grants him increased strength but also directly extends his fading lifespan, pulling him back from the brink of death. The rules are simple: the more his lineage expands, the longer and more powerful his life becomes. Armed with this unprecedented opportunity, the centenarian patriarch issues a bold decree to his sprawling family tree. Regardless of age or gender, he commands every son, daughter, grandson, and granddaughter to go forth and multiply. What begins as a desperate bid for survival quickly transforms into a grand campaign to fill the mountains with his heirs, turning family expansion into the ultimate key to his newfound immortality.
