Lord Puyan of Qingchi Palace in the Immortal Realm, the only son of Bai Jue, the true god of the ancient world, and Shanggu, the lord of the ancient world. His divine power was sealed by Apocalypse a hundred years ago, and he was expelled from the heaven by the ancients. He was raised as a nominal disciple under Emperor Hua of Shandong, Daze..Due to an unintentional mistake, the soul of Fengjun Fengyin of Wutong Island was scattered. By chance, he led the water condensation beast Ayin to travel through the three realms to reunite his soul for his beloved knight.

Kuching is an ancient god, whose original name is Yuan Qi. He is the son of Shanggu and Bai Jue.Since he was born with a divine status, Tianqi was worried. In order to prevent him from causing trouble, Tianqi blocked his divine power and asked him to change his name to Kuching and worship under the master of Dong Huashang in Dazeshan.

In the scene where Feng Yin meets Kuching, Feng Yin comes to the world on Feng Island and is made things difficult for him.Upon seeing this, Kuching kindly spoke out to protect him, and during this encounter, he mistook Feng Yin for Hua Shu and regarded Hua Shu as his benefactor.In order to win her smile, Kuching offered the Fire Phoenix Jade to Hua Shu on the day of Feng Yin's Nirvana.

The spiritual power and soul that Feng Yin has cultivated for hundreds of years are all stored in the Fire Phoenix Jade. Only by absorbing all the spiritual power can she truly achieve nirvana.However, at this critical moment, Kuching fell down and blood dripped on the Fire Phoenix Jade in his hand.This accident caused the origin of chaos to be awakened in his body, uncontrollably devouring Feng Yin's spiritual power stored in the Fire Phoenix Jade.

Because of Hua Shu's casual words, Kuching ruined Feng Yin's nirvana, causing a dramatic development in the story.
