Is the story of Qi Guoran true or false? Is there the original text?

The story of Qi's "ran" comes from "Tomb Robbers Notes". It is just a fictional paragraph and not a historical fact. In ancient China, the dignity of the emperor was inviolable. Ministers were not allowed to talk, move or look around when they went to court. They could only look at ivory or jade tablets, let alone look at the emperor. Otherwise, they would be beheaded. Anyone who sweats or farts in the hall will be punished. Therefore, it is very common for even ministers standing in the main hall to not know what the emperor looks like after being in court for several years.

Original text of the paragraph:

The ancients spoke very concisely and very skillfully. For example, one: "Ran". I remember a king of Qi State asked his military advisor a question, The military advisor nodded and smiled and said, "Yes." The monarch went back and pondered for a long time whether he agreed or objected to the "ran". As a result, he became sick from overwork. Before he was about to die, he told the military advisor the answer he had considered. Asked the military advisor if that was what he meant at that time, the military advisor chuckled and said, "Yes." The emperor died immediately.
