I Know of the Apocalypse, so this time I will build The Strongest Base

Kai, an apocalypse hero died with his friends from a Tier-10 Titan. With his plot-armor, he reincarnated back in time during the times where the world is at peace and doesn't know the existence of zombies. Kai will use his futuristic knowledge to gain resources to build the strongest base and find reliable teammates that will fight for him. This is my first serious novel, so you might notice some irregularities. This novel is created by a math and economics nerd, so expect seeing stock markets and auctions. I will also touch on what I think is the best way in combatting zombies in a dooomsday scenario. Don't think yet that this is retarded as I am yet to familiarize myself with the English language particularly in writing. There will be knowledge nuggets like what is the most optimal auction system for a limited number of identical goods, best type of economic system and government in the apocalypse, and best way to build a base in a specific environment. There are things, so strap on and read. I still have research to worry about, so I might not update frequently, so read at your own risk.
