Ao Fan time-traveled to the Primordial World, becoming a member of the declining Dragon Clan, and gained two cute daughters. At a time when the Lich tribulation was unfolding, the entire Primordial World was fraught with crises. Fortunately, Ao Fan obtained the Dad-Raising-to-Get-Stronger System: as long as he raised his kids, he could obtain all kinds of rewards, from the God-Killing Spear to the World-Purifying Green Lotus, everything you could possibly want. From then on, Ao Fan began beating up various big shots across the Primordial World, even becoming the Lord of the Dragon Clan and the First Sage of the Primordial World!
