[Reborn into the foremost family in Huaguo + invincible protagonist + ruthless and decisive + multiple heroines]
A demon ancestor is reborn in the modern city. “Heavenly Dao, get out here!” After robbing the Heavenly Dao of a hundred strands of Hongmeng Qi, I accidentally stumbled into a cave. Inside was the sealed Demon God, Luo Hou. “Either sign a master-servant contract with me and become my muscle, or have your soul scattered into oblivion...”
In his previous life, Ye Tian was the Demon Ancestor of a great world. Just as he was on the verge of unifying the world, the disciple he had treated like his own son stabbed him through the heart with a single sword. “I treated you well! I treated you like my own! Why?”
It seems okay, but I hope the author doesn't end up with a bad ending and writes more protagonists.
