In the 21st century, Zhou Chen, a social animal, traveled to the waiting room of a border inn in Dachu, and was accidentally bound to the "Emperor's Troublemaking System" - but every time the system released a task, a strange snake-like pattern always flashed in the corner of the interface, as if there was an ancient conspiracy to control the emperor. He activated the novice gift pack by slapping the second-generation officer in the face, revitalized the inn with take-out flyers, and confused the court officials with Excel ledger sheets. He made counterattacks all the way from the ninth-level inspection, and tricked a princess in trouble into joining the team and formed a shadow guard to defeat the conspiracy of Japanese spies. When Wu Yue was sent out to build infrastructure and grow potatoes, an old ancestral jade pendant suddenly became hot, and the royal bloodline that he didn't even notice was gradually revealed; and the "mute boy" he had rescued always had special ink hidden in his sleeves that only Japanese spies had. After the improved warship violently defeated pirates and exposed the forged jade seal of Japan, the real princess who was living in Japan found that her childhood token was exactly the same as the mobile phone pendant that Zhou Chen brought when he traveled through time. After discovering that the system was revealed to be the remnant spirit of the Yamata no Orochi in the decisive battle to destroy the Japanese, he ascended the throne wearing a dragon robe embroidered with hot pot, held a royal complaint meeting and pushed a steam locomotive, and finally unified the world. He only occasionally thought: Is his time travel really a coincidence?
