The Unique Guardian Beast Master in Cultivation World - Chapter 34 - ‘The Spirit Gathering Soul Cultivating Formula

The Northern Ice Fields had no boundaries.

The Winter Wolves hid within the snow, the Frost Tigers growled incessantly, and the roars of Giants echoed throughout the land. Many species struggled to survive in the icefield. At the same time, a baby White Dragon possessing the power of time broke out of its egg and opened its platinum-colored eyes.

Years later, the legendary Time Dragon appeared, moving freely between the endless past, present, and future.

A young orphaned boy named Mu Yi is saved by an old travelling Taoist Priest. They travel the world ‘scamming’ people by ‘exorcising ghosts’ and ‘slaying demons’, that is until the old Taoist Priest dies and Mu Yi is forced to realise that all is not as it seems. He was told stories of armies of ghosts, hordes of zombies, horrifying demons, and worst of all, the cultivators who controlled them.

Mu Yi takes his first steps towards rising to the top of this dark and cruel new world.
