"Daughter of the Xue family, don't look back. On a full moon night, the building is filled with blood." Is this a curse in a nursery rhyme? Twin blood contract, if Xue Zhijin, who grew up in the Xue family, is not a member of the Xue family, then who is her mother? Is "human sacrifice" just for the hundreds of years of wealth and glory of the Xue family? Can the reversal of the contract be successful? Layers of questions, peeling off cocoons, Chinese horror, breathtaking! All horrors can only be overcome by facing them head-on! Will it become more and more brain-burning, surrender or sacrifice? It would be better to destroy all this evil! Let the rebellious blood burn away the darkness!
