Hello can anyone help me find a novel? I remember it was about a city that was transported into a different world where they survived for 100 years but some mist is loosing its effect and great calamity will come. MC remembers his past life and starts preparing for the inevitable. He starts by helping his father dissasemble beast corpses and helps granpda granddaughter pair. Grandpa has some problem with hands which he helps to fix. I also remember that is the place where MC lives there is a fight and he helps protect is family by putting points into shooting or something to remember his past level of skill or something. That's all I can remember. Thanks for any help.
It took me a few hours of searching through 1000 chinese novels but I found it. If anyone is interested the name is Oh My God! Earthlings are Insane!
