An Egg at the Beginning of Rebirth

I transformed into a senior fellow from the Immortal Sect, but was told that my real body was an abyssal egg. The master patted my eggshell lovingly: "One egg is passed down to three generations. If the egg is still there after you leave, you will be the future of our clan." My junior brothers and sisters were respectful on the surface, but secretly called me a "monster". Until the day the demons invaded, the potential system suddenly awakened—— Only then did I know that I could not only evolve into an abyss lord, but also have the mission of destroying the Three Realms. And the little junior sister who always smiles at me is pressing the magic knife against my heart: "Senior brother, see you in Demon King City."
