Tang Mo sat in his own seat, listening to a series of reports from Nangong Hong. Supporting the internal war in the Dahua Empire was a national policy of the Tang Empire, but this policy actually had an ultimate goal.
The internal war in the Dahua Empire affected the trade of the Tang Empire, especially the import of oil from Qin Country and a series of slave smuggling to the Orc Empire.
Although these businesses were not the ultimate lifelines of the economy, they indeed affected the speed at which the Tang Empire made money.
Because of this, the Tang Empire, to some extent, did not particularly wish for the internal war in the Dahua Empire to go on endlessly.
The best outcome would be for Zhao Yu's military and Zhao Kai's military to inflict heavy losses on each other, then reach some level of reconciliation, allowing the Tang Empire to profit from the situation and secure the benefits it wanted.
