The Invincible Little Demon Lord

You’re a genius? A demon king? An alchemist? A weapons master? A Celestial Venerable? In my eyes, you’re all trash! Cross me, and I’ll kill you. Cross my little brother, and I’ll kill you too. Get on my nerves, and you’re dead! Wondering how I got so powerful? I have a System to conquer the world! A library of heavenly cultivation arts, divine beast-taming talents, and a treasured furnace for alchemy! Charming beauties? Heh, I was born with that gift. Everyone loves me, and flowers bloom wherever I go! What? You say I’m cheating with overpowered abilities? Heh, you’re right. I just love watching you losers wish you could kill me, but fail miserably!
