Harem Investment System: Getting Money And Women - Chapter 130: System Upgrade

“Did you know? I was once the most powerful person in the world, undefeatable even by the gods. If only I can retrieve my body, I could resurrect once again.”“So what?”“So... who has hidden my corpse!”

I became a wizard of the Illusion Magic School and decided to create a virtual reality with illusion magic to play a tabletop role-playing game (TRPG).It was great to create a virtual reality, but I was in trouble because there were no suitable players. During that time, I received an offer to be the professor from the Royal Academy.The offer was to use illusion magic to fill the students’ lack of practical experience safely. And so, I became a professor at the academy.“Send me back, send me back to that world right now-!”“Outer god, someday an outer god will be our doom, we’ll all die!!”“I am not the bastard of the Redburn Ducal Family. I am the foremost disciple of the Great Namgung Clan, Namgung Qinghui!”But it seems there is a bit of a misunderstanding.This isn’t a spell for dimensional travel, kids. It’s fiction…

“That monster’s prefix is two hundred meters long?!”“It’s back. Who can stop it?”Isaac never planned for Celestia: The Eternal Realms to change his life. The game promised 100% immersion, a completely realistic world powered by quantum brainwave interfaces. But the moment he entered the game, Isaac was thrown into an entirely new world, no longer the player, but the played. His character, a “Lesser Hyena-Wolf,” came with the dreaded “Weak” prefix, reducing his stats by 20%.Isaac quickly realized that this wasn’t a game he could simply log out of. It was his new life, and there was no escape. To survive, he had to evolve, to fight, and ultimately, to conquer. He knew the game inside and out, but this wasn’t the same reality he’d logged into. This time, he would have to become the monster, instead of fearing it.Every step he took, Isaac grew stronger. He realized that monsters weren’t bound by the same rules that governed the players. He could evolve, gaining new powers and unlocking Monster Reputation. With every kill, every victory, he unlocked a new level of power. The prefixes that marked his growth—Normal, Strong, Especially Strong—were a testament to his evolution. And the players began to whisper.

It was just a normal morning but it was unknown to many that the apocalypse already started.

The origin was not determined but the infected started to appear after a cosmic event happened just outside of the Earth’s atmosphere.

The people and animals turned into man-eating mutants and zombies while some of the lucky ones gained superhuman abilities. Every living creature that had not “turned” started to evolve as the whole world was affected by the Mutagen.

However, it seemed that Earth also had its hidden side that humans would discover in a very uncanny way.

And was Mutagen the last of it?

Unfortunately, not.

Follow Mark, an Otaku, a Gamer, and a Shut-in that got trapped in the middle of the apocalypse due to an uncanny reason. Using his unconventional thinking, knowledge, and abilities, how far can he go in surviving the apocalypse filled with zombies, mutated beings, and dangerous people as a survivor in a world that was changing for the worse.
