Having Wives And Raising Children Levels Me Up

“Hey, have you heard?” A noble asked his fellow colleagues.“About what?”“I heard that lazy son of the Rin Household walked up to the Chan Household last night to offer the Head of the Chan Household his Rin family potion-making secret recipe in exchange for the hand in marriage of the Chan Household's beautiful daughter.”“What? You mean he asked to marry the talented, beautiful fairy goddess of this era?”“Yep, you heard correctly.”“Oh my goodness. Is he smoking mushrooms for him to be so desperate to sell his own family secret? And what makes him believe he could ever have a chance with that beautiful goddess?”These were the words whispered by the nobles about a young man, but the young man's body was also the same person Austin's soul had transmigrated into.However, upon awakening in this new Game-Like World, Austin's eyes widened in surprise when he read the words displayed on a screen in front of him.[Congratulations, Host! You've awakened the “Be Intimate And Multiply System”][With this system, you can now grow stronger every time you become intimate with your wives, and if your wives give birth and you raise them, you become invincible, as well as your little ones!!]“Woah!! For real?”“Hehehe..... I guess it's time I live my new life to the fullest.”Months passed, and Austin finally had children of his own.[Congratulations! You taught your first daughter a new word. Reward: Five Mana-Hand Constructs for combat.][Congratulations! You chased away the monster under your second daughter's bed. Reward: Heavenly Demonic Sword for chaos and destruction.]More prompts appeared before him, but rumors began to spread among nobles once again.“Have you heard? That useless son of the Rin Household married the Elf Countess, and now she has given him twins.”“What? But I heard he seduced the King's daughter and now she spreads her legs for him every time she welcomes him.”“Nonsense. I heard the beautiful fairy goddess of the Chan Household moos like a cow every night in her bed chambers, but every morning that Austin walks out of her mansion.”“Impossible, that man has to be stopped, because I heard his children are capable of causing mass destruction.”And so, many nobles, rivals, and adversaries allied together to harm Austin in his very home, but standing between him and his enemies were his children, each of them saying in unison: “If you wish to dare touch our father, then you must get past us first.”Hearing this, Austin couldn't help but smile while saying, “Aww, they grow up so fast.”
