"The Emperor commits a crime, he faces the same punishment as the commoners!"
"The Human King truly is the guardian deity of the mortals, what a grand spirit! This is what a true ruler looks like."
Seeing the lofty Emperor kneeling on the execution ground, waiting for the moment of execution, the people of the Nine States not only didn't feel that this act was trampling on the Emperor's dignity, but they were actually very excited, deeply satisfied from within.
"Princes and generals, are they but seeds?"
Repeating this line a thousand times over isn't as direct as sending the Emperor to the guillotine.
Turns out, the Emperor, just like them, must be punished when he errs, must be beheaded, restrained, and kneel on the ground. The Emperor is a man too, no different from them.
