Forgotten Title Please read description.

I'm looking for a Chinese Webnovel about a Zombie apocalypse... possibly alien invasion (I can't seem to remember which). Might be BL too. With the usual extreme nationalism and racism. Apparently, the MC was reborn a year or so before the apocalypse but he didn't keep it to himself but involved the military so when it occurred, they were prepared.

 

There's a bl title where the mc was from the cultivation era and MC's sister is the one reborn. It's a Harem with OP protagonist.
Lord of end of world

 

This is a bit vague, do you have more description that you remember?

Thanks.
I finished Lord of the End World today so it's not it.

 

Thanks!
I think it's harem... Actually I only read the synopsis, it's here on NU but I just can't remember the title.
