Born as a boundary keeper, his life depends on the safety of the three realms.
Liu Xiaohuan, an ordinary young man, grew up in a remote village, but he inherited the fate of the ancient guardian lineage. A broken token and a "Boundary Keeping Manual" allowed him to step from being ignorant of the villagers to embark on the path of suppressing evil, crossing souls, and guarding the world.
Evil spirits are rampant in the world, the immortals are deceitful, undercurrents are surging, and the demon world is about to be stormy. The walls of the Three Realms are loose, demons are spying on the world, and people's lives are in danger.
He does not love his position as an immortal, nor does he covet eternal glory. He only uses his moral integrity to guard peace and protect the people around him.
The gentle healer, the fiery demon lord, and the cool and cold envoy, the three emotions are intertwined and accompany him all the way.
From guarding a village, to guarding a realm, to guarding the world.
Let's look at the young man who takes guardianship as his way and his heart as his boundary. He changes his fate against the will of heaven and creates a soul-stirring journey to the world of guardianship!
