The dog demon Yue Jinghong has cultivated for a hundred years, and has only one wish in life: to become an immortal.
An elder of her clan taught her a ten-character shortcut to immortality, with every word worth its weight in gold: A dying husband's tears, and you shall leave the world an immortal.
In other words: if you want to become an immortal, your husband has to die first.
Yue Jinghong immediately took a liking to Li Jibai, the famous sickly scholar in town, the young master of the Li family.
He was twenty, had been constantly taking medicine since childhood, and had just been given less than six months to live by every doctor in town. He was practically the perfect "husband" candidate.
Just then, the Sun family, promised to the Li family in an arranged marriage since birth, sent a letter from a thousand miles away to break off the engagement. Yue Jinghong acted at once, pretending to be the Sun family's daughter, Sun Shiqing, and marrying into the Li family. Her plan was simple: behave herself for half a year, wait for Li Jibai to die, collect his dying tears, and ascend to immortality.
On their wedding night, she looked at Li Jibai, pale-faced and coughing violently, and prayed devoutly beneath the moon: "Heavenly Dog God, please make sure my husband dies right on time!"
The sickly Li Jibai, courtesy name Lanjie, was a most unusual man.
By day, a gust of wind could knock him over, and he was too weak to get out of bed. At night, he took her over walls to investigate cases and catch demons, moving as swiftly as the wind.
Yue Jinghong waited anxiously for half a year, but instead of her husband's dying tears, she got one piece of bad news after another.
Li Jibai's health improved, and he became vigorous in bed.
Li Jibai solved one bizarre case after another and was about to head to the capital to take up an official post.
Li Jibai put on an official's robe, and the Li family rose from ruin.
Seeing that Li Jibai wasn't going to die, Yue Jinghong had no choice but to come clean and plan to find another sickly husband.
On the night she confessed, a red moon hung in the sky.
Before Yue Jinghong could say a word, a huge wolf's tail slowly emerged from behind Li Jibai.
So shocked that her own dog's tail came out, she blurted, "...You're a demon too?"
Li Jibai slowly curled his wolf tail around hers. "I am a werewolf, and Honghong is a dog. We're of the same kind, and made for each other."
Yue Jinghong felt like crying. After a long while, she managed to say, "...The elder said a werewolf is a fox."
"Honghong, your husband is both a fox and a wolf."
"..."
A fox that lures dogs, a wolf that devours dogs.
That is a werewolf.
