Demon Hunter Blood Pact

From the end of the Sui Dynasty when Li Shimin chopped off the head of the first corpse demon on the Yanmen battlefield to the modern day when a female college student in Nanjing downloaded scans of ancient books left by her ancestors in the library - ten dynasties, ten relatively independent novels, each with ~120,000 words, tell the story of a family (Liu family)'s inheritance history of demon subjugation spanning 1,400 years.
