Compared to the former emperor, the Noble Families in the capital fear the current emperor more.
Don't be fooled by the emperor's constant smiling appearance; he can change his face instantly, giving them no time to react. By the time they realize it, disaster has already befallen them.
Before making a move, the former emperor would first offer courtesy and then bring out the troops. But the emperor is different; he uses troops first before courtesy. The former emperor was ruthless; the emperor is even more so. The most terrifying thing is that the emperor is extremely intelligent. If the Noble Families attempt to act clever before him, it's akin to showing off inferior skills before a master craftsman.
Unable to outplay him with intrigue, or fight him head-on, the Noble Families can only behave obediently in front of the emperor. Fortunately, the emperor does not press them excessively; as long as they don't go too far, he usually turns a blind eye.
