Civilization is destroyed and records lost. Only Dudian survives in a cryogenic sleep. Three hundred years later, Dudian wakes up and must become Dean to survive. Who can he trust in this world overrun by monsters without and within?

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!
