Now, as a member of the Saxe-Coburg-Gotha Dynasty, I swear to witness and protect the rise of this land with my life, uniting all Australians and New Zealanders under a new name to witness our rise: Australasia forever!

Growing up in poverty, Sunny never expected anything good from life. However, even he did not anticipate being chosen by the Nightmare Spell and becoming one of the Awakened - an elite group of people gifted with supernatural powers. Transported into a ruined magical world, he found himself facing against terrible monsters - and other Awakened - in a deadly battle of survival.
What's worse, the divine power he received happened to possess a small, but potentially fatal side effect...

One of the few self-cultivator who exist in this modern world; due to an unfortunate event, completely destroyed his body in an explosion. Using all his effort to save his primordial spirit, he ended up in an strange magical world and had to start all over again. From a fallen aristocrat to the Warlord of Chaos, this can no longer be summarise as legendary; this is the life of the God of War.
