This is a world of cultivation, where spiritual energy is abundant, but the strong prey on the weak. Cultivators are divided into the righteous and the wicked. The righteous rule openly, while the wicked lurk in the shadows. Ghost cultivators and demonic cultivators are hunted by everyone. The world has nine great continents, dotted with sects. The righteous sects of the Xuan Sect lead the way, controlling the resources needed for cultivation. Without spiritual roots, ordinary people can never join a sect.
The protagonist is a naturally blind orphan, abandoned in a mass grave. Everyone says he is a useless cripple who will never cultivate in his entire life. But fate has other plans. Mistaken for an evil being, he is killed by a righteous cultivator. As his soul is about to dissipate, he encounters a taboo figure among the ghost cultivators: the Demon-Sealing Cultivator. This old monster sees that the boy's fate is extraordinary. Though blind, his mind's eye can see into the netherworld, making him an ideal match for the cultivation method in the Netherworld King Asura Ghost Canon. The old monster pours ghostly energy into his body, defying fate and changing his destiny. From then on, he walks the path of proving the Dao through slaughter. Ghostly energy is yin and baleful, nourishing the body through killing and making him stronger with every battle. He cultivates the Asura Dao, a path of no return. Benevolence and morality mean nothing: everything is decided by the blade. Ghostly cries unleash wails for a hundred miles; the Ghost Shadow Step lets shadows kill; the Asura Slash sends heads rolling. He cultivates no heart, only killing intent. His eyes are dark, and his heart is haunted. Step by step, he slaughters his way from an insignificant insect to the Great Dark Asura Heaven, the master of the ghostly path, earning a supreme reputation through bloodshed.
