He was suddenly summoned to another world one day. Monsters poured out, a huge disaster incoming. His ability the lowest. [Player's level is low] [Your level is hopeless] It doesn't matter whether you're the chosen warrior, a talented wizard, or someone who travelled back in time. One must do everything they can, in order to survive. The Regressor's Instruction Manual. "It doesn't matter if I'm trash." Is there anyone who wouldn't do anything they could to survive?

One day the world became a game. Monsters are suddenly appearing and killing humans and humans have become players and must fulfill quests! A player that was given a second chance after the fall of mankind, Kim Sehan. Will he be able to beat the system that made the world into a mess?

Kim GiGyu awakened as a player at the age of 18. He thought his life was on the track to success, climbing 'the tower' and closing 'the gates'... But even after clearing the tutorial, he was level 1. He killed a goblin a day, and he was still level 1. Even after 5 years, he was still level 1. "Who would have thought that this kind of player would exist." No one knew.

" You have been selected as the fittest"
" With your talent, the survival rate [5%] in the Selha Latna is lower. "
"Do you want to commit suicide? Y/N"
"X-"
Less than a 5% chance of survival. 22 years. Countless battles with the demon dogs. In this hell; I'm surviving alone.
Hidden behind level 5, together with the outrageous hidden stats!
The extreme survival record of the strongest level 5 swordsman Ryu han bin who was thrown into this other world with just a sword.

Jinhyuk, a gaming Nutuber, was the only person who saw the ending of the game [Tower of Trials]. However, when the game’s popularity declined, it became difficult for him to continue making a living as a gaming Nutuber. Since he already saw the ending of the game, he was about to quit playing. But that day, [Tower of Trials] became reality, and Jinhyuk, who knew about every single thing in the game, took over everything faster than anyone possibly could! “I’ll show you what a true pro is like.”

5 years after the world changed, the final boss appeared. [The final boss for area Earth, the Frost Queen, has appeared.] The final boss! If we can just defeat her, our lives will go back to normal! The top five players in the world, including Specter Seo Jun-ho, finally defeated the Frost Queen... But they fell into a deep slumber. 25 years passed. "A second floor? It didn't end when the Frost Queen died? Specter awakes from his slumber.

"Mc's returned from hell, after hundreds of years to save Humanity!"

eon-woo had a twin brother who disappeared five years ago. One day, a pocket watch left by his brother returned to his possession. Inside, he found a hidden diary in which was recorded “By the time you hear this, I guess I will be alread
Obelisk, the Tower of the Sun God, a world where several universes and dimensions intersect. In this world, his brother had fallen victim to betrayal while climbing up the tower. (not enough space..)

I want an S-Rank skill too! I want it so badly, I could die for it!
[You have awakened an S-Rank skill.] [But it only works when you die.]
HUH!? WHAT’S THE POINT OF GETTING ONE IF I DIE !?

THE SUMMARY IS SO LONG SO, BASICALLY THIS IS ABOUT A MC WHO GOT BETRAYED BY HIS COMRADES THEN HE GOT REINCARNATED TO THE PAST, AND NOW HIS GOAL IS TO TAKE DOWN THE ONE WHO BETRAYED HIM.
