After the ancient war between gods and demons, both sides were nearly wiped out, and the Heavenly and Demonic Realms were left severely weakened. The gods and demons who lost their bodies in the war had no choice but to exist as spirits. To wield their powers, they sought out suitable mortals to possess, becoming their "Guardian Spirits." Mortals who possessed a "Guardian Spirit" came to be known as "Spirit Masters."
A hundred thousand years later, a college student fresh out of school and starting his first job somehow became the Spirit Master of the ancient Demon God Chuo Long. How could he possibly control this legendary, unpredictable, and savage demon god? And with a storm soon brewing across every realm, how could he stay out of it? If there was no other choice, he could only grit his teeth and charge in!
