The cynical little detective travels through the glorious Tang Dynasty. His left hand searches for traces, and his right hand follows the clues. With his eyes open, he sees clues, but with his eyes closed, the reasoning is confusing. Although he has no money in his pocket, he attracts bees and butterflies. Although he hangs a knife on his waist, he only kills fierce bandits and murderers. Empress Wu: What kind of official position do you want? I want to share the world equally with you. This Tang Dynasty is yours during the day and mine at night!
