In the 17th year of the Republic of China, Dukou Township suffered a severe drought. Bloody water suddenly gushed out from the ancient well in Majiazu Mountain, and red mist filled the mountains every night. The villagers thought that the dragon's veins were broken and the dragon's anger brought disaster, and people were panicked. Ma Pingchuan, a young man who returned home, did not believe in ghosts and visions and insisted on exploring the truth. This offended the clan leader Ma Shouyi and was placed under house arrest and surveillance.
Ma Pingchuan, who was exploring the ancient well alone late at night, discovered that all the strange phenomena were man-made illusions: the well water was an antiseptic potion mixed with cinnabar and animal blood, the red mist was made from special smoke materials, and there was a pottery jar liquid storage mechanism buried decades ago hidden at the bottom of the well. The so-called natural disaster was all an elaborate scam.
After investigation, it was found that this scam started between Ma Shouyi and his son. In order to monopolize the ferry waterway and fertile farmland along the river, and unify the control of the two villages, the ancestors of the Ma family fabricated the legend of dragon veins, used ghosts and gods to intimidate the clan, suppressed dissidents, expelled fellow clansmen, and even secretly killed people, controlling the entire town for decades.
Ma Pingchuan, armed with government evidence and clan secrets, crossed the river to the township office to complain, only to find that the township official and the head of the security team had been bribed to form an alliance of interests with Ma Shouyi, destroying evidence and confusing right and wrong. At the critical moment, the Nantan branch of the Majia family, who had been expelled for many years, returned to his hometown to seek justice. The oppressed business gangs along the river and awakened villagers joined in, creating a complex situation of multi-party game.
In the multi-party confrontation, layers of conspiracies were exposed. The greed for power and profit of two generations of clans and the corruption and favoritism of the government were completely exposed. In the end, everyone gave up their grudges and put family blood and local justice first. They filled up the fake ancient wells, redivided the fields and waterways, and erected monuments to warn. Corrupt officials and evil gentry were convicted in accordance with the law.
