The Supreme Magus, one of the strongest beings in the Divine Realm, teacher of 100 God Heroes, died to protect the world from his corrupted self. With a stroke of luck, he landed in the world of Terra. Many years had passed before he woke up again. Just as he's beginning his journey on this new world, he suddenly received an invitation to a Chat Group--a chat group that connects many parallel worlds.

Rediscovering his past, recovering his strength, and even surpassing his past self. Step by step, he would become stronger, and all of that starts from a chat group.
