Guo Wang Bi Xia is the pen name of a Chinese writer known for creating the original web novel series Congqian Youzuo Lingjianshan. The pen name translates to "His Majesty the King". The creator is from Beijing, China, and is recognized as a prominent online literature author whose writing style is noted for being light and brisk in tone.

The most significant original work by Guo Wang Bi Xia is the xianxia web novel Congqian Youzuo Lingjianshan, which translates literally to "There was once a Spirit Blade Mountain". The novel began serialization in 2013 on the Chinese literary platform Chuangshi Chinese Network. The story falls within the xianxia genre, which typically involves martial artists and immortals in a fantastical cultivation setting.

This original web novel served as the foundation for a multimedia franchise. A manhua, or Chinese comic adaptation, of the series was launched on the Tencent comics portal in 2014. The work was subsequently adapted into two anime television series. The first season, titled Reikenzan: Hoshikuzu-tachi no Utage, premiered in January 2016. The second season, titled Reikenzan: Eichi e no Shikaku, began broadcasting in January 2017. Both anime adaptations were co-productions between the Chinese company Tencent and the Japanese animation studio Studio Deen. The anime was simulcast in both Chinese and Japanese language versions. In these productions, Guo Wang Bi Xia is officially credited as the creator of the original story on which the anime is based.

Beyond the animated adaptations, the creator's original work was also adapted into a live-action television series titled Congqian Youzuo Lingjianshan, which was released in 2019. The recurring artistic identity of Guo Wang Bi Xia is centered on xianxia fantasy, characterized by a blend of cultivation themes and comedy, often described as a "hilarious xianxia" work.
