Born a Guardian of the Boundary, he bears the fate of keeping the Three Realms safe.
Liu Xiaohuan is an ordinary boy raised in a remote village, yet he carries the destined legacy of an ancient line of boundary guardians. A broken token and the Scripture of Boundary Guardians lead him from an ignorant villager onto the path of cultivation, where he suppresses evil, guides spirits, and guards the boundary.
Evil spirits run rampant in the human realm, the immortal sects scheme against one another, dark currents churn in the underworld, and storms gather in the demon realm. The barriers between the Three Realms are weakening, the Heavenly Demons are eyeing the human world, and all living beings are in grave danger.
He does not covet the position of Immortal Venerable or the glory of a thousand ages. With his steadfast Daoist heart, he guards the peace of one corner of the world and protects those by his side.
A gentle healer, a passionate demon lord, and a cold underworld emissary: three intertwined affections accompany him on his journey.
From guarding a village, to guarding a realm, to protecting all living beings in the world.
Witness this young man take guardianship as his Dao and his heart as his boundary, defy fate, and forge a stirring path of immortal cultivation as a Guardian of the Boundary!
