System Notification: Your King of Passivity talent was activated through killing the Elit Demon Clan Warrior. You have automatically received the Critical Strike (Passive) Skill.

What? I got another passive skill.

I have way too many skills, I can barely see the end of my skills panel.

I need to be low-key, low-key.

This is the story of a game grinder who used his passive skills to destroy legends.

The world had changed when the System arrived, alongside the Cataclysm that filled the world with monsters. The technology was gone, replaced by classes and skills that allowed the people to fight back. When Devon ended up as a Blacksmith, a class that didn’t grant Intelligence, he had to face the reality, that his old career that he loved - mathematical sociologist - was over. Instead, he had ended up as yet another discarded member of the production class, overshadowed by the existence of the System Shops to the point of total marginalization. But, what if all he needed was to reapply his scientific thinking to the System...

Neuer travels through the world of pirates, is adopted by Bermer, and becomes Nami’s older brother!

The Awakened Talent Copy System can copy anyone’s talent in a certain aspect at will!

What kind of experience will it be when Neuer has Shanks’ domineering talent, Kaido’s physical talent and Hawkeye’s swordsmanship talent?

Even the ability of a devil fruit can be copied by the system as a talent!

Many years later, Neuer turned the sea upside down with a talent that surpassed everyone in the world.
