Li Yao rode a bat, heading towards the Hinterlands for a mechanical blueprint — the Death Reaper 4000 model.
The prototype of the Death Reaper 4000 was the Wheatfield Puppet, a type of harvester used in the human world.
The Wheatfield Puppet originated from a scarecrow. It was invented by the goblins of a venture-capital company, who managed to dump it into human kingdoms. The original use was to guard wheat fields and drive away boars, birds, and the like.
The venture-capital company was one of the top five financial firms run by the goblins, an organization infamous for their goal to monopolize the world's mining and oil collection industries. To protect their interests, they established a specialized group of pirates.
But it cannot be denied that the invention of machinery was deeply ingrained in the goblin's bones.
As the human kingdom fell into chaos, a thief group rose to power and occupied a large region of the kingdom.
