A brief description of the light novel The Eternal Supreme:
One of the Conferred Martial Emperors, Gu Feiyang, passed away in the Tiandang Mountains and was reincarnated 15 years later as Li Yunxiao of the State of Tianshui, embarking on a heaven-defying journey against the innumerable geniuses of the time.
The nine levels of the Martial Art; the Divine Realms of the ten quarters. From then on, the whole world fell into chaos!
