“Better to have and not need than to need and not have.”

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!

When Song Qinghan woke up, he found that he had not only transmigrated into another world, but also… had a ball in his stomach. He thought the original owner of this body had left a total mess to him. But it turned out there was a piece of precious jade hidden in it. Looking at the six-pack abs of Wu Dahu, he rubbed his hands with great excitement. Farming, your job! Hunting, your job! Giving birth, ahem, you worked hard! But surgery… leave it to me!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
