However, misfortune finally befell him, because he was too obsessed with resurrecting his wife Liu Lifen. He tried to defy fate and use forbidden arts but he failed miserably, and his obsession led to his death.

But just as his soul began to dissipate, Long Tian's soul was sucked in by a black hole. And by the time he regained his consciousness, he was already in a world he had never seen before.

And from the memory he knew that his current name was Xia Tian, ​​a sixteen year old debauchee. His father was killed by a mysterious person , and he himself was also a cripple.

But who is Long Tian? He was a genius cultivator with various abilities, and was well known by many nicknames. He is determined to return to his peak, and fight against his own destiny to become the strongest in this new world.

Dual cultivation and apocalypse—words that mix like oil and water. There's nothing charming about seducing feral women on the road.

However, when Kaze Lexicon, the emperor of the Immortal Plane, got transmigrated into the past, he refused to give up his debaucherous ways—apocalypse or otherwise.

Armed with the knowledge of the future and an encyclopedia of overpowered cultivation techniques, he immediately set forth to obtain resources and build a lavish settlement to live a comfortable life dual cultivating in the apocalypse.

However, while it's obscenely protected and powerful, he finds himself in another predicament. The cultivators farming humans for their war, and the desperate humans, become enemies far more dangerous than the zombies and monsters that afflict humanity.

Join Kaze as he rebuilds his reputation from a bullied weeb, obtains wealth, builds power, starts a faction, makes lemonade, trains his people, protects his past lovers, conquers settlements, and fights humans, monsters, and cultivators, all for the sake of two obscene goals: enjoying life and building an army of engineers to bring modern technology to the higher planes.
