What is the paradox that Ji Xiaolan experienced in Urumqi 300 years ago?

Although superstitious, Ji Xiaolan himself recorded that he saw evil thoughts turn into black gas after gangsters died in Urumqi.

Ji Xiaolan was demoted in the thirty-third year of Qianlong. He recorded in detail the strange things that happened after beheading in Yuewei Caotang Notes.

In the same year that Ji Xiaolan was demoted to Urumqi, there was a rebellion in Changji. A group of exiled prisoners, somehow, sneaked into the arsenal and occupied Yongbyon city. Although it was quickly suppressed by the imperial court, strange things happened during the beheading. It is said that after the gangster was beheaded in the Woods, I don't know if the resentment turned into black gas, which will float everywhere in the middle of the night, and people will get lost like ghosts when they encounter black gas.

Ji Xiaolan thinks these black gases are evil. Because it has been the truth since ancient times that evil does not suppress right, Ji Xiaolan thinks that masculinity should be able to restrain these niggers. He ordered the soldiers to stay in the Woods at night and attack at the sight of these black gases. After a while, the black gas disappeared.

Black gas is the reason for the transformation of bandits' resentment. Although it feels far-fetched, the ancients were superstitious after all. There is nothing to say about this. But now we have no way to know what the black gas in the forest is, which may be some kind of creature or gas like miasma.

In fact, when Ji Xiaolan was demoted, he was very depressed. After all, he was angry when he was transferred from the central government to the local government. Of course, we don't know the truth of this matter. Maybe it's just that Ji Xiaolan proved his ability in the name of ghosts and gods in order to be transferred back to the central government more quickly. After all, the theory of ghosts and gods is so mysterious that even Qianlong will care. And Ji Xiaolan can exorcise ghosts and make trouble. Through books, through word of mouth, and perhaps in public opinion, it can make Qianlong change his mind faster.
