With each day of defeat and losing their grounds of their Undercity bit by bit to the humans and monsters, the Demon Rats' morale was dropping rapidly. The rumours regarding the death of their Air Force General had been made true once the Demon Rats in the Air Force had been given orders by Mage General Prideblood.
And what was worse was that the humans were relenting in their fight, something which most of the veterans had dismissed them as weak beings were refuted at each and every turn of the battle. The newer Demon Rats could see the vigour of the human cultivators returning to the battle not defeated but ever more eager to kill them.
Their numbers might not amount to much but their resurrective abilities were something that even the Demon Rats believed that it was only a matter of time before they lost such an ability and died permanently. There was no such thing as infinite magic and somehow they thought it was proven true within the second day of the battle.
