I Went Dark, and in a World of Global Lords, I Became a Merchant

In the age of lords for all, I turned into a merchant? What use could a merchant possibly be?

Failure: A random thing somewhere increases tenfold!

Behemoth Lord: "My Behemoths are so powerful! One punch can kill a whole bunch of them."

Angel Lord: "My angels are invincible from the start. Their holy light shines across the earth."

Han Fei: "Brothers, I'm in a bind too. If you don't die, I'm the one who dies. Things are already bad enough. How am I supposed to survive if they get ten times worse?"

Angel Lord: "Help! A whole bunch of goblins are attacking my territory! Can anyone save me?"

Han Fei: "I've got some Origin Crystals here. Interested?"

Angel Lord: "Damn it, borrow one, pay back a hundred? That's loan-sharking!"

Behemoth Lord: "A whole bunch of reckless goblins are launching a mad attack on my castle. All my angels have fallen in battle. I need to borrow ten thousand Origin Crystals!"
