Deep in a cold, dark stretch of space, a probe records something impossible: nine colossal dragon corpses hauling an ancient bronze coffin. Back on Earth, thirty-three former classmates gather for a reunion after graduation, only for the coffin to carry them off to an unknown planet. To survive, they must take up the path of the ancient gods and enter a world of cultivation, where their friendships are tested and the pursuit of power and immortality can lead to ruin. At the heart of the story is Ye Fan and his ascent toward the heavens. Adapted from the first part of Chen Dong's Zhetian trilogy, this long-running ONA blends action, adventure and science fiction across 208 episodes.
