Wei Wo Du Shen

Xianxia, directly translated to 'immortal heroes' comprises a number of popular genres including 'Cultivation', is a genre of Chinese fantasy heavily inspired by Taoism and influenced by Chinese mythology, Chan Buddhism, Chinese martial arts, traditional Chinese medicine, Chinese folk religion, Chinese alchemy and other traditional Chinese elements.

Protagonists are usually "cultivators" who seek to become immortal beings called xian. Along the way, they attain eternal life, supernatural powers, and incredible levels of strength. The fictional cultivation practiced in xianxia is heavily based on the real-life meditation practice qigong.

The stories usually include elements such as gods, immortals, yaoguai, ghosts, monsters, magical treasures, immortal items, medicinal pills, and the like. They often take place in a "cultivation world" where cultivators engage in fierce and usually deadly struggles to acquire the resources they need to grow stronger. Oftentimes, the initial setting is reminiscent of ancient China, but the stories usually become cosmic in nature, with the protagonists attaining godlike abilities, sometimes creating their own planets, galaxies or universes. While the primary focus is action and adventure, there are also romance-heavy stories.
