Since assassinating her inside the royal palace isn't feasible, Nangong Tianyang decided to lure his sister outside.

He had already devised a plan to invite his sister to a banquet under the pretense of an apology, but in reality, it was a setup for an assassination.

Once outside the palace, Nangong Tianyang was prepared to reveal all his cards.
