The King of the East provided them with a great motivation.
"This is the weakest Independent Group you can face, since Ji Xinghe is not here.
You also don't need to worry about Ji Xinghe using remote piloting to participate in the battle. I don't need to explain further how severe the communication interference of the Second Canyon is. The mecha control without communication support cannot possibly span thousands of kilometers.
If Ji Xinghe could use his mecha control across thousands of kilometers, we wouldn't have to fight; we'd just surrender. But even if we surrender, Ji Xinghe would still kill all of us.
So, to avoid being killed by Ji Xinghe, we must kill him first. When we can't kill him, we must annihilate his Independent Group to make him lose his mind with anger and hatred, then kill him.
I'll say it again, this is the weakest Independent Group you can face. Go ahead, annihilate them."
