The character of the people from White Eagle is something Yamamoto Ichio knows only too well.
So he purposely did this to deplete White Eagle's hidden reserves even more.
Only by doing so can he weaken White Eagle's power, so that it will be easier to deal with these people after entering the Great Xia Empire.
When plotting against the Great Xia Empire, they absolutely must secure the situation in favor of their Ointment Kingdom. With such vast interests at stake, why would they want to share with countries like White Eagle?
Yamamoto Ichio's subtle movements are unbeknownst to Gill; in his view, once a barrier is formed, it is all-encompassing protection. There are no stronger or weaker segments.
At this moment, he's calculating how to make other countries exert more effort, especially those shorties from the Ointment Kingdom.
