Even someone who has lost all sense of decency and conscience actually cares about face, though in most cases, when someone truly loses all conscience, their pursuit of face takes on a very strange direction.
For example, in ancient times, making a king always feel indebted to you would pretty much mean you're not far from having your family exterminated and your house raided.
The Second Prince of Qi Country now found himself caught in this contemptible circle of self-consistent moral logic.
He felt that none of this was his fault, nor was it the fault of the people of Shenwu. All the problems he faced were actually because his father refused to promote and trust him, to hand over the entire Qi Country to him.
As for blaming Tang Country, he resisted the idea deep in his heart, for he did not dare. For Tang Country was so powerful that not even the people of Shenwu could defeat it, so powerful that he didn't even dare to entertain the idea of blame.
