The story mainly tells that during the invasion of the Eight-Power Allied Forces, the national treasury was robbed, and the security bureau insisted on retaining the credentials after retaining the remaining property. In order to protect the credentials from being robbed again, the helmsman took the credentials and concealed his name and hid in Changluan Town, which was unknown to the world.
The birth of the helmsman's child caused a series of jokes.
Many years later, the chief eunuch of the imperial court was bribed by a foreigner. After getting the news, he went to Changluan to snatch the credentials.
As a result, the helmsman and the eunuch started fighting openly and secretly. They create trouble for each other, and while the two sides are fighting to the death, a third-party mysterious figure gets involved again...
The plot is as intricate as a death note, tense yet hilarious.
