Copy Everything a Hundredfold: I Won't Even Spare My Dao Companion

[Anything can be copied ten thousandfold + Overpowered Protagonist + Decisive and Ruthless + Leveling Up + Lots of Women] Jiang Beichen was born into a cultivation world and awakened memories of his past life after turning eighteen. He discovers that he’s caught in the middle of a massive clan-annihilation crisis! Then he awakens the Ten-Thousandfold Copy System! Anything and everything can be copied! As long as it belongs to me, I can copy it! Pills, magical artifacts, talismans, money, physical strength, the amount of spiritual energy in my body (mana), and even my vitality (health bar) can all be copied. I can choose to stack the copies to increase their power, or simply duplicate their quantity. Even abstract things like fortune, lifespan, and talent can be amplified ten thousandfold! Jiang Beichen: “Holy crap!” “This cheat is insane!” “Is this even fair? How can anyone play if they don’t nerf it?” Then he discovers... he can even copy his Dao companions ten thousandfold! What?! While everyone else painstakingly cultivates, I cultivate through dual practice! Who can grind for experience like me? I’m at it day and night! Jiang Beichen’s blood boils on the spot! Wait, what? Have I just unlocked the cracked version of this cultivation world? Tremble, world! No, wait! The Myriad Worlds!
