The Xuantian Gate at the top of Kunlun Ruins was born out of chaos. Its bronze title page is engraved with ancient runes, half bathed in morning light and half bathed in shadow, like an eternal boundary monument of the good and evil in people's hearts. For thousands of years, countless practitioners have knocked on the door here. There are no scriptures or techniques inside the door, only the true heart is reflected, and outside the door are the paths they have chosen to return home.
