Eliminating Demons in the Song Dynasty

In the third year of Chongning, Bianliang. There are foxes croaking at night on the tower of Xiangguo Temple, and corpses floating in the Bianhe River remain intact for three days. The owner of the wonton stall under the Zhou Bridge has two black glass eyes. The world just thinks it's a fairy tale, but the Demon Exorcist Guards have an inferior team. Shen Yan, a minor official in Chenliu County, whose father was bitten to death by a tiger monster that descended from the mountain ten years ago, half of his body has not been recovered. He has only had one thought since he was a child - to kill monsters. That night he encountered a hanged demon dragging people to death on the bridge. He killed it with a knife, and there was a "ding" in his head, and the system was activated. Kill a demon and smoke for a year. The pig demon lasts twenty years, the fox demon eighty years, and the great demon five hundred years. The methods of cultivation and advancement include entry, small success, great success, and consummation, which are piled up layer by layer. From the stone bridge in Chenliu to the Zhouqiao in Bianliang; from a hanged demon to leading 300,000 demon-killing guards to guard the Huaihe River—— What Shen Yan has to do is actually very simple: If the demon eats my father, I will eat the demon back. If the demon wants to come down the mountain, I will block the mountain.
