The Nebula's Civilization - Chapter 190: Efficiently

I had a supporting role in a modern fantasy.

The loyal dog of a villain with an angel’s name, Cheon Sa-yeon, and an unfortunate supporting character who died on his behalf, Han Yi-gyeol.

In order to escape from Cheon Sa-yeon and survive, he must use the protagonist, Ha Tae-heon.

But Ha Tae-heon, who he thought of as a lifeline, was infinitely indifferent to him. Rather, Cheon Sa-yeon showed interest.

But besides that, something strange happened.

The events that occurred in the original story had advanced, and the gate and monster levels had risen. Even the people were “different” from the original.

The original version I was trying to use was wrong.

After dying, you wake up and realize you've been reincarnated as a background character who is judged as human trash.The decision to change your destiny comes instantly.Discovering that your identity isn't as simple as you thought, you feel favored by the heavens when you manage to become a powerful character.Katase: You won't fool me. I'll expose you for the pervert you are.Murayama: ...Thank you for saving us.Issei: Motohama, what happened to you? How are you so powerful?Rias: If you join my peerage, I wouldn't mind being yours.Sona: You beat me in the game. That means you're now my fiancé.Yasaka: Honey, Kuno wants a little brother.Kaori Houjou: Shinji-kun, let's go on an adventure.Kaede Kazama: Shinji-kun, thank you for saving me from that ball.Rie Sawada: Shinji-kun, I'll wait for you. You'll be my future husband, fufufufu...Changing known history and taking it in a direction not even his eyes could perceive, he didn't stop no matter what. Not even the other world was safe from his clutches.Lexia Von Arselia: My hero, and my future husband...Shinji advances without stopping.“I, Shinji Motohama, swear here and now that I will reach the top of both worlds.”

Sky Ishiyama is a nerd with Photographic Memory who after the bumps and turns in his life, turned to be a Doomsday Prepper.

The story takes place in our world where our MC was diving through the Dark Web just for fun and discovered something that could only be found in books, movies, novels, manga, anime, or games.

Zombies, Walkers, Freaks, Infected, Biters, or whatever you may call them.

They're fucking real.

Ever wondered what you could do in a zombie apocalypse where you actually know what you're doing? Actually surviving properly while preventing stupid deaths? Doing what is right and necessary? Or better yet, actually doing what you shout in the monitor when you're watching a film?

Our MC is coupled with the knowledge of not just fighting z's but actually surviving by securing his home, finding allies, scavenging for supplies, building a community and so much more.

If you could, kindly like the tags I've put up and it would be huge, huge help for me, thanks in advance! Also, a comment, a review, or even a vote of a single power stone would help me out a lot! Thanks again!
