The Demon Rats might have been injured by the armoured spirit defenders but they were still able to move through the battlefield with ease. It was their first time fighting against phantom armoured dudes and only through luck that their weapons were able to not just take a hit but also attack them back.
They had forgotten that their weapons had been tempered by the System's science research department which was capable of cutting almost anything as long as there was some mana flowing through their weapons.
And even though the genes of these Demon Rats had not been modified to take in mana, their mobility suits had that function installed in them like a dynamo engine, allowing them to perform mana focused hits if there was sufficient magic energy stored in those suits.
