I have never before seen such a shameless person
A quote from Zhuge Liang in the 1994 Romance of the Three Kingdoms. Zhuge campaigned to Chang'an and faced the Wei army near the River Wei. The Wei advisor Wang Lang boasted that he can force Zhuge into surrendering by words alone. The two met on the battlefield and engaged in a fight of words. Wang state that the Han had been wake and was succeed by Wei. Wang promised titles and wealth on Zhuge's surrender. Zhuge questioned Wang's loyalty to the Han emperor to whom Wang swore to serve. Wang died vomiting blood after Zhuge uttered the line, considering he was 76 at the time.
