Mercenary King Starts with Hell Squad

Brothers are bleeding, I have returned from hell, and the Mercenary King System has awakened! They laughed at me as a lunatic, so I formed "Hellfire" - only accepting monsters, not mortals! When the superior "Mercenary Emperor" teamed up with the ten legendary mercenary groups to issue a killing order to me, I picked up my wine glass and chuckled at the enemies all over the world: "Either kneel down and surrender, or... Be burned to ashes by my hellfire." Step out from the mountains of corpses and seas of blood, and forge your throne from the bones of your enemies. My gun is truth, and my rules are order! See how the former rising star led his army of monsters, burned down the old dynasty on this battlefield of blood and fire, and was crowned the only god.
