Many Children, Many Blessings: Starting from Marriage, I Become Invincible by Adding Points

[Many children, many blessings + extreme skill point allocation + ruthless decisiveness + multiple female leads] Zhou Xuan transmigrates to a fantasy world overrun by demons and at the end of a dynasty, starting in hell mode. He was destitute, harassed by a local bully demanding repayment of debts, and had a delicate wife who had married into the family to bring him good fortune. In a moment of despair, the "Many Children, Many Blessings" system is activated! By entering into marriage, increasing affection, and having children, you can gain affinity points and become infinitely stronger! While others were still diligently cultivating, Zhou Xuan quickly leveled up his technique to perfection, easily stepping into the next realm. In this dark and chaotic world where dynasties have collapsed, demons roam freely, and strange phenomena have resurfaced, Zhou Xuan only wants to protect his family and live a peaceful life. But years later, when he stood atop the Saint Realm, with a row of fairies, goddesses, demon concubines, and empresses standing behind him, he couldn't help but fall into deep thought: "Back then... I really just wanted to pay off my debts and live a good life with my wife!"
