One day, an ordinary young man was suddenly summoned to another world. He didn’t know why or how it happened, but the world he entered was in serious danger. Terrifying beasts were attacking cities and villages, and the people were living in fear. The land was full of magic, warriors, monsters, and danger at every turn.
Like others who were summoned before, he was supposed to become a hero. But when his abilities were tested, everyone was shocked. His talent level was the lowest possible. The system even said:
[The player’s talent level is at rock bottom.]
[Almost all the numbers are hopeless.]
He couldn’t fight well. He had no powerful magic. His strength, speed, and intelligence were all at the bottom. People laughed at him. Others gave up on him. Some even told him to run away and hide before he got himself killed.
But the young man didn’t give up. He looked at the world around him and made a decision.
“It doesn’t matter how weak I am,” he said. “I’ll use everything I have to survive!”
He studied magic books, trained with broken weapons, and watched how others fought. He couldn’t become a warrior, but he learned how to move smartly. He couldn’t cast big spells, but he found simple tricks to protect himself. Every day, he pushed his limits.
He used his brain when his body failed. He used patience when he lacked power. He avoided danger when he had to, but he always looked for a way forward. When others relied on strength, he relied on knowledge, timing, and determination. Slowly, things started to change.

Regressor Instruction Manual Plot
Lee Kiyoung discovered that even weak skills could be strong when used correctly. He learned to combine small tricks to make powerful moves. He picked up items others ignored. He made traps, studied monsters, and found their weak points. While other heroes burned out or fell in battle, he survived—and grew stronger.
People began to notice. The “hopeless” player was now winning battles. He saved towns, rescued soldiers, and surprised powerful enemies. He didn’t have raw power, but he had something else: a will to survive and adapt no matter what.
His story is not about a chosen one with great gifts. It is about someone who started with nothing, but refused to give up. In a world of beasts, magic, and danger, he proved that survival is not just for the strong. It’s for those who use everything they have and never stop trying.
This is the tale of the weakest summoned hero… who became unstoppable in his own way.
