What I don't understand is how they could even fall for an obvious trap like that. I mean, the fact that he so "desperately" wanted that banquet should've already rang all the alarms in this blondies head in the previous chapter, and the fact that they so desperately wanted to take the guards away from him should be more than enough to make him realize something is going on, yet he sees nothing, so I guess he's just a moron. Quite frankly, any person who has brains (regardless of whether they work or not) should've been even more vigilant after "obtaining the country without bloodshed", since it was obvious the king didn't want to give the country to him, which is he challenged you in the first place. So expecting him to actually honor such a deal is outright idiotic and the emperor should be executed for stupidity.
