Changsheng Martial Arts Begins to Gain Proficiency by Answering Questions

Traveling through the Wei Dynasty and becoming a low-level policeman in Wu'an County, Xu Yunsu faced a desperate situation of negative merit and bad luck at the beginning. Fortunately, his golden finger has mutated - others rely on swinging a knife thousands of times to gain proficiency, but he relies on "answering questions"! Bite! It is detected that the host successfully solves the core puzzle of "The Stolen Case of Treasury Silver", and the proficiency of Black Tiger Sword Technique +1000! [Ding! The host perfectly answered the "Fei Qian Reform" economic strategy, and the medicine clan's talent proficiency was +500, breaking through the realm bottleneck! [Ding! The host sees through the disguise of the "Eight Gods Sect" demon clan, gains +1000 merit points, and extends his lifespan by ten years! The party struggle in the court is fierce, the monster clan on the border is watching with eager eyes, and the six major cultivation systems are undercurrent. Xu Yunsu originally wanted to steadily accumulate merit and gain proficiency by "solving questions", but unknowingly, he was involved in a chess game that overturned the world from a police officer. The masterminds behind the scenes such as Shi Gaohan and Elder Wuxiang were arrested one after another. Xu Yunsu looked at the full proficiency on the panel and sighed helplessly: "I really just want to answer a question, why am I invincible?"
