As the Ancestor, My Strength Increases with the Number of Descendants

Lin Bai transmigrated to the oriental mystery world where strength prevailed. He obtained the Multi-Son and Multi-Fortune System. For each additional offspring he reproduced, he would be rewarded. The offspring's growth would also feed his own cultivation! [Number of offspring: 1. Gain a life span of 100 years and increase the Lin family's fortune.] [Number of offspring: 10. Gain a lifespan of one thousand years, rewarding the legendary magic treasure, the Heavenly Mirror.] [Number of offspring: 100. Gain a lifespan of 10,000 years, rewarding the guardian spirit beast, the Violet Flame Phoenix.] Is there such a thing in the world? Lin Bai, who had mediocre talent, directly found his little sister and started dual cultivation. They started a man-making plan to start a family in the fantasy world. Other people were cultivating, while Lin Bai was making a baby. Others were competing for resources, but Lin Bai was still making babies. Unknowingly, his offspring had dominated the entire fantasy world!
