The Emperor's anger is understandable. He was threatened by the Emperor of Wei Country to hand over the city, or Wei Country would bring troops to destroy Moli Country and cut off his head. The Fourth Prince really stepped on a landmine this time. Of all places, he chose to side with Wei Country, coincidentally when Wei Country was preparing to invade Moli Country. No wonder the Emperor is so furious.
The Emperor's ruthless expression made the Second Prince's heart shrink. It seems that in the future he, too, must be careful not to step on the Emperor's landmine. Otherwise, even father-son affection will be unreliable.
As a monarch, the Emperor had many women and even more sons; dozens of them, big and small. To abolish one or two princes naturally wouldn't matter to him.
