Chapter 37 He's in a secret relationship

......

The King of the Demon Kingdom went into the dungeon where they imprisoned Zerha and the other demons yesterday with the demon knights accompanying him.

Hm? The King frowned when he noticed something from the cell bars. “What is this?" he asked the demon knights. The demon knights look at the melted cell bars and notice that the other bars are continuing to melt.

“...I'm not quite sure what is this, but I think this is some kind of acid, your majesty..." one demon knight replied.

“Acid...this is no ordinary acid, this is a venom. I'm certain of it. Only beasts like serpents can have venoms than can melt hard things, like rocks and steel." said the demon knight who was with Prince Morloch yesterday.

“Let's say it was a beast, but how did they enter the Kingdom without being noticed?" Did someone pretend to be a demon, and bring it secretly?“Who are the demons that were prisoned here?" the King asked.
