Cui An only frowned slightly when he saw the four guards being killed; he did not lose his temper. Then, he looked at Lu Zhou and asked, "I heard a rumor early in the morning that someone has killed Yu Chenshu. Are you the rumored expert with the surname Lu?"
Li Yunzheng said in a deep voice, "Cui An, are you not going to kneel when you see me? How dare you disrespect your master!"
Cui An ignored the furious Li Yunzheng and only said, "Your Majesty, you're still young and easily influenced. After this matter is dealt with, I'll naturally apologize to Your Majesty. The other four Grand Dukes are on their way here as well."
Li Yunzheng wanted to continue reprimanding Cui An, but Lu Zhou raised his hand to stop him.
Lu Zhou's expression was calm as usual as he asked, "So, you're Cui An, one of the five Grand Dukes?"
If Cui An's men were around, they would definitely rebuke Lu Zhou for referring to Cui An by his name instead of title.
