Three hundred years ago, the Lord of the Demon Realm led a million demon troops to break through the space barrier, crushing the mountains and rivers with their iron hooves, and destroying all living beings. At that time, the ancestors of the guardians gathered all the high-level mystics, sacrificed the flesh and blood of hundreds of strong men, and devoted their entire spiritual power to seal the demon lord back into the abyss. They also used the source of spiritual power as a guide to create a transitional space between the demon world and the human world, naming it the White Realm. This barrier has become the last barrier in the human world. Generations of guardians have been stationed here, using their profound strength and lives to protect the lights of thousands of families behind them.
