Fantasy: Reborn as a Tiger Demon, the more children, the stronger you become.

[Many children, many blessings] + [Decisive and ruthless]
Having transmigrated to a fantasy world, Hu Xiao becomes a tiger demon and activates the "Many Children, Many Blessings" system.
With each offspring born, their strength increases!
And so, this continent gained an invincible tiger demon that specialized in plundering females.
Whether it's an extremely alluring fox spirit or a fiery and domineering dragon girl.
Or perhaps a holy maiden of a sect, a princess of an ancient kingdom, or a daughter of a noble family...
None of them can escape his clutches!
Years later, Hu Xiao had become the supreme demon ancestor and the holy venerable one of the human race.
And this is just the beginning; even the vast and boundless upper realm will be filled with his bloodline.
