Blood in Amber

When history student Lin Feng held the "Pocket Watch of Doom", he thought he had the power to rewrite the tragedy - he successfully traveled to London in 1881, and stopped the knife that Jefferson Hope was swinging at Enoch Draper in front of No. 3 Garden Street, Lauriston. However, the moment of victory is the beginning of collapse: the books he left behind from modern times, including the "Study in Scarlet" that details the ending, fell into Hope's hands. An Avenger who knows all the methods of the future detective and understands his original destiny has thus "evolved". Holmes was led to Eastern Europe by a secret letter, and the deaths in London did not stop, but became more sophisticated, hidden and difficult to trace - toxicology, psychology, and even the use of legal loopholes, the butcher armed himself with knowledge. What is even more heart-stopping is that every crime scene contains cold clues from modern times that only Lin Feng can understand, as if a pair of invisible hands are showing him: Look, every time you intervene, you are just providing more delicious sacrifices to the giant beast of history. Lin Feng was forced to face the consequences of his good intentions: not only did he fail to save anyone, he instead catalyzed a perfect murderer that could not be captured by 19th-century logic, and dragged the innocent next generation into the whirlpool of revenge. This is no longer a duel between a detective and a murderer, but a war between a naive intruder and the iron law of time - every time he repairs a crack in history, time and space will repay with deeper wounds elsewhere.
