Whether Lusen City is willing to send troops to help the Beamon annihilate the Naga army is not something Rommel alone can decide; he hasn't reached that high position yet.
Launching a war not only costs countless warriors' lives but also involves a large amount of money and resources. As the saying goes: "There's always someone willing to risk their head in a business deal, but no one will do a losing deal." To get the cunning Fallen Elves to send troops, there must be some visible benefit, otherwise, who would foolishly volunteer to be the scapegoat?
The issue is, the Feilengcui Lord, Lucian, didn't give Rommel any promises at all. He just spoke off the cuff, demanding Lusen City send troops to assist. His condescending tone and stance had clearly taken the Fallen Races as his vassals.
