Qing Dynasty Qianlong period, Zhenjiang City, south of the Zhao Village, there is a small farming family, her husband, Zhao Tian, a simple and upright, his wife, Li, hard-working and virtuous, the couple! The two men plowing and weaving, love, although life is bitter but also lived a happy and fulfilling.

The Zhenjiang countryside, eel is quite a lot of people often catch to steam fried, that is, as a delicacy. One day, the husband Zhao Tian plowing, plowed out a 3-foot-long eel, carry home. Wife saw her husband work hard all day, rarely eat meat, so put some oil and salt spices, carefully cooked.

She couldn't bear to eat it, but prepared a pot of rice wine and sent it to the field to comfort her husband. After eating it, Zhao Tian suddenly suffered from stomach pains, bleeding from his seven orifices, and fell to the ground.

The clansmen reported to the government, the autopsy investigation, Zhao Tian was indeed poisoned and died. So, the government will be Li's capture, beaten, to murder her husband crime, beheaded after the fall.

At this time, coinciding with Ji Xiaolan stay in Zhenjiang, detailed questions about the case, quite strange, dissecting the body to take samples, can not find Li's use of what is the poison. And Li's love with her husband on weekdays, the townspeople know. This case must have a hidden message, they are determined to find out.

Ji Xiaolan sent people openly and secretly, more than half a month, no results. One day, he moped back to the house, by chance to look through a folk medical books, there is a section of the record to attract his attention.

Said Jiangnan countryside, there is a strange eel, hibernating in the field, every to the full moon in mid-autumn, will look up at the moon, until the moon, so named "moon eel". This eel is small, one in ten thousand, but it is extremely poisonous. I'm not sure if I've ever seen one before, but I'm sure I've seen a lot of them.

The next day, that ordered his family out of a notice to the townspeople to buy eels at a high price. The townspeople scrambled to catch, more than a month to buy eels ten thousand, put a tank, placed in the yard. On the night of the full moon, I saw an eel looking up at the moon until the moon fell.

Caught, but drilled into the eel pile. Ji Xiaolan has always been smart, so he ordered people to carry a number of large tanks, eel in the cylinder, and then in the moonlit night, to see it in which cylinder, and then divided, so several times, they will be "looking at the moon eel" separate out, raised at home.

Not a day later, coinciding with the countryside fair, the government called the plaintiff, in the fair in the public review of the case. Ji Xiaolan announced that Li was not guilty, Zhao Tian accidentally ate the poisonous eel, poisoning death. The crowd did not believe it and talked about it, only because the townspeople often catch and eat eels and have never been poisoned.

Since then, Jiangnan people eat eel especially cautious, Ji Xiaolan cleverly solve the strange case is also rumored to be a beautiful story.
