Wu Xuan, the ace instructor of China's top-secret organization "Dragon Soul", codenamed "King of Hell", only wants to lay down and farm after retirement. Unexpectedly, a three-year-old girl fell out of thin air in the yard, claiming to be his biological daughter Xiao Jiuwei in his previous life, and the reincarnation of the first immortal emperor in the Nine Heavens Immortal Domain. What's even more outrageous is that the paternity test showed that the baby was really his biological child! Xiao Jiuwei told him that the real daughter of the fairy world (her biological mother) had everything taken away by the counterfeit Li Youwei. Her cultivation was completely ruined, her memory was sealed, and she became a hard-working slave in a small company. Wu Xuan took a look - Dare you bully my wife and daughter? It's against the sky! No matter what the plans of immortals or the conspiracies of heaven, they are all younger brothers in front of the "King of Hell". He took Little Kyuubi on the road to find his wife, killing international mercenary groups and fairy law enforcers along the way, vowing to overthrow the impostor's lair.
