tower defense: ashen land

Ash a soldier at 22 years of age, retired after receiving a bullet to his right arm making him a disabled, even though they had to cut his right arm off, it wasn't that bad since he can "excuse" himself off of the pointless war his oh so proud country have.
4 years has passed since then and ash retired to be a gaming streamer, due to his laid back attitude and very nonchalant personality not many people watches his stream.
his family are a classic case of a mistake, that kind of mistake. in order to live he had to stream almost everyday, and add that to the fact that his right arm are nonexistent, not many employer wanted a "damaged" person to work.
then suddenly the game he was playing becomes reality, he of course are excited by the prospect of not streaming everyday and working his bones out, and would you know it, he has a system...
=======================
ash is very selfish and usually doesn't care about other people, but of course he's still a human so if he can, he will help other people if there are no risk.
expect gore description and fucked up stuff.
also the game is a tower defense game! my favourite!! and ash too I guess.
chapter are varied in quality and this is a casual project.
and might I remind you that I'm an incompetent bufoon who can't get stuff right or accurate enough, I also am still new to this...
HUGE twist incoming!

such are the way of life, it's full of holes and traps and lies and betrayal but no sooner it will soon be over, the truth will be revealed and the soul to unite.

act 1: rough beginning.

please do not lose hope in humanity, it is our fate to be this way and soon we shall overcome it, no matter if it takes year, decades, millennium, for one day we shall live our life in glory, though the pavement we built are from blood and bodies of whom have fallen, they shall be proud of our accomplishment.
