The consciousness of a Great Magus suddenly returned to his original body on earth, just before he transmigrated into the magic world.

Nothing has changed, it's still the same earth.

However, when he looked at earth once more as a former great magus, he discovered earth was not as simple as he knew it to be.

Hidden magus, legendary races such as vampires and werewolves, they do exist, ruling the world through the shadows.

A century after the Spirit Qi Awakening, the world enters a new era. Humans are able to absorb the world’s awakened spirit qi, allowing them to tread on a new path—spirit qi occupations!
