In the Dayu Dynasty where immortals and demons intertwined, {Shen Yan} awakened the "Tianyan Dao Body" - his luck defied the heavens to avoid death, his understanding was a thousand times greater than that of martial arts, and his yin and yang sense was able to distinguish authenticity. However, he was a down-and-out scholar who was ridiculed as a "weak and useless". Accidentally bound to the "Thousand Realms Case-solving System", you can travel through fairy and demon copies adapted from real history such as the Anshi Rebellion and the Jingkang Disgrace, solve unsolved cases, beat up bullies, and tear apart traitors! The maid Qinghe loyally protects the master, the self-mirror spies on Daoji, the love rival in the past life secretly assassinates, and the AI imitator confuses the audience! Shen Yan uses solving cases as his blade, uses his luck as his momentum, and relies on his heaven-defying understanding to understand the rules of fairy magic. He breaks the rules and breaks the rules. He grows up step by step in infinite time and space, and transforms from a useless scholar into a case-solving emperor who is in charge of the order of all worlds!
