A Case in the Time of Cholera

In 2032, during the era of cholera.

There was a kind of cigarette that let smokers choose between tar and tar-free with a switch, between toxic and nontoxic. Yet young entrepreneur Yu Xiangyang and his companions dropped dead in the street after smoking it.

A week later, every AI forensic examiner in the country, the Little Sheep, was arrested. A female nanovirus that was hermaphroditic had been implanted in them. Anyone carrying the male strain who came into contact with it would die. Even more dangerously, if this disease were to combine with the cholera virus, the world would become hell.

Fifteen years ago, when famous journalist and writer Gao Ailian was murdered, Yu Xiangyang was the one who provided the lead. In the present day, Yu Xiangyang is once again collaborating, this time with businessman Liang Weida, who was Gao Ailian's first love.

The police and the criminals match wits in a battle of cunning.
