Chocolate was a Devil from Hades.
His rank wasn't as high as a superior Devil, but Chocolate felt that his capability was on par with other superior Devils.
However, there was a rank system in Hades, so he didn't receive the treatment he deserved.
As a powerful Devil commander, he could only lead a small vanguard unit and fight at the frontline.
His Devil unit was more than sufficient to deal with these common Underworld creatures, so he was indignant.
With his capability, he could lead an army instead of just a vanguard unit.
The superior Devils in Mammon's army looked down on him.
When he returned, he was going to teach those generals a lesson.
He thought that Eternal Kingdom would cut off the Mana source of the Teleport Portal outside the construction site, but it didn't happen. Instead, the Teleport Portal was well maintained, and an endless stream of Goblins came out from it.
That was correct, they were Goblins.
