A Century of Slacking Off in the Restroom, and I Become the Supreme Fishing Emperor

[Legion-building + cultivation System + mecha armor + overwhelming power + getting stronger by slacking off + mastermind behind the scenes + laid-back protagonist + cozy daily life]

The world is being destroyed? Doesn't matter. The takeout wasn't delivered! Then everything can disappear...

On the surface, I'm a lazy wage slave. In reality, I'm a cultivator with an invincible secret art.

While heroes livestream their desperate battles, I slack off and raise an army of Underworld Gods. A rich lady thinks I'm poor and cooks for me every day! She ate the spirit rice provided by the System and became the second-strongest person in the world! Want to know who's first?

Then the world-ending witch arrived. I got fed up and hit the “Underworld God Mecha” start button.

Livestreamed worldwide: Is that black mecha a secret weapon from a civilization at the pinnacle of technology?!
