The ancient god foresaw that the immortal world would suffer heavy losses and sent his only bloodline to the mortal world. He only hoped that he could live out his life in peace.
Named Hua'an, he met Gu Ming's childhood playmate in Hua'an in the mortal world. Lu Hua'an was killed and only Lu Hua'an was left. Gu Ming comforted and accompanied Lu Hua'an to find the real murderer. Gu Ming knew that Lu Hua'an didn't understand his feelings for Lu Hua'an. He was rescued by Yunxi during his practice. Gu Ming mistakenly thought that Lu Hua'an liked Yunxi and finally left Lu Hua'an.
Philosophy: Lu Hua'an didn't know Gu Ming's thoughts. After they finally got married, Lu Hua'an fell to protect the Three Realms.
