Rainy Night, the Knife Does Not Sleep

The Gu family in Linjiang was wiped out overnight, and only Gu Tingchao survived. Many years later, he followed an old lamp book, a broken knife, and an old account of the salt road that had been deliberately rewritten to return to the murderous incident. He originally thought he was checking the Gu family. Later I found out that what he was investigating was the most invisible layer in the world - some people used lamps to convey orders, some borrowed books to exchange lives, and some used centuries-old cases to put countless people's names into the same dark network. What Gu Tingchao wants to do is not just revenge. He wants to pull this net out of the darkness inch by inch.
