Su Yan spent his whole life escaping from the shadow of his "prophet" father, but after his father's death, he received an unsent letter. The letter predicted that he would kill an innocent man within seven days. In order to break free from the shackles of fate, Su Yan stepped into the taboo divination room left by his father and tried to decipher the truth behind the prophecy. However, he found that cracks began to appear in his memory, and the people around him also showed strange faces one by one. Every day, the details of the prophecy are quietly changing, and Su Yan's name flickers in and out of the death list. He gradually realized that he had become a "variable" in a larger game - only by finding out who was manipulating the prophecy and tampering with fate could he save innocent people or himself. With an extremely compact rhythm, this book cuts through the boundaries between fate and freedom, and lifts the fog of memory and reality, asking at every reversal: Who is weaving fate, and who can truly escape?
