Forgotten Title Cultivation

I don’t really remember much of it but what I can remember is that the mc lived in the last human standing city, he was a genius and became a guardian, he was supposed to go out and help other humans come to safety but the mayor of the city was afraid that he was gonna lose his position to the mc so he colluded with the demons to kill the mc.
I think mc name was Lu tangyi or close

 

Although I don't know the novel off the top of my head, I'm pretty sure it's an original.

 

Tales of Demons and Gods? Might not be it though

 

A Chaotic World

 

Yeah it's A Chaotic World

 

Nah, the MC name in TDG are Nie Li and the City Master is his Father-in-Law.
