Condemned
Cale should ask asterie to teach him how to build those troublesome robot that gave them a hard time during battles in his previous life. He needs all the advantages he could garner; who knows the lesser demon whom have gotten intelligence might decide to join the invasion since he is twisting fate.
At last the enemy not to op. It just sugestion though, maybe you can let bigger country become sacrafice. Because big country will become to trobelsome. Their politican is full of themself, they like status of higher position their contry in the world and will not easy to countrol. Or you can make this chalenge how mc will do in the future to control this wild bunch, intimidation will not work and they will try to act & accuse mc as villian so they will have reason to declare a war. With threat of extintion over their head mc do not have time for war aggaints each other. The reason of their confidence is nukes.
