Comments of chapter undefined of Strongest Necromancer Of Heaven's Gate

So It was a shadow organization that wanted to overthrow the king. I wonder what the backstory for this one will be. Thanks for the chaps

Lux working hard so he needn’t join Nero’s guild! Anything goes for his goal!

Thank you for the chapter

Could Lux not have used the corpses in town and cast corpse explosion on the rats? Even if it would not kill them all it would definitely slow them down and make the flute guy wary of him which would also slow the rats advance.
