In Victorian England, occult practitioners and the Nightmen Police, who hunted occult practitioners, were at odds and engaged in a fight to the death. Legend has it that one of the occult practitioners was a mysterious merchant who ran the world’s largest underground black market in the occult arts, offering a variety of rare treasures. Word says that the Nightmen have a newly appointed young detective whose decisive actions have solved many cases, and occult practitioners are terror-stricken hearing his name.

Duan FeiZhou: Good, both are me.

He transmigrated to this era because he accidentally clicked on an email titled “Congratulations on your million dollar inheritance” and confusingly agreed to join the Nightmen’s side to fight against the occult practitioners.

Who knew that the next day he would inherit a mysterious inheritance from his uncle – the owner of the world’s most prominent black market of secret arts underground trading… This was a bit awkward.

Duan FeiZhou decided to stay away from the strife to avoid falling off the horse and became a salted fish.

On the one hand, crazy black market customers hope that the black market will close down as soon as possible. On the other hand, the Nightmen are negatively idle, hoping that he is quickly fired. However, the more he rushed customers, the more the business of the black market became red hot. The more negativity, the more he was promoted in the Nightmen.

Z: Oh well.
