The Demon King Reborn and Returned

The human and demon races formed an alliance and attacked the Demon Clan, leaving countless demons dead or wounded. The old Demon Clan leader, Ancestor Long Tian, fell in battle. Before he died, he used the last of his strength to preserve less than half of the Demon Realm. He ordered seven of his subordinates to defend it, rebuild their strength, restore the realm, and await his return.

But when he returned, he made many friends from different races. He would brave fire and water for his brothers, and stand by them through thick and thin. As he learned more and more, his worldview was repeatedly turned upside down. He came to witness the vastness of this world, and found himself facing one mystery after another, waiting to be solved.
