A modern history buff transmigrates into Li Yi, son of Li Shimin, and binds himself to the All-Purpose Trouble-Making System. In the prosperous Zhenguan era, he begins a thrilling life of sign-ins, stirring up trouble, and making big things happen. A sign-in at the imperial gardens rewards him with high-yield seeds, piling Chang’an’s granaries into little mountains. A draw in the library gives him a glassmaking formula, letting him sell sparkling glass all the way to the Western Regions and rake in a fortune. When the Turks invade, he whips out a terrain analysis map and new tactics, leading the Tang army to turn the grassland cavalry into a sightseeing tour group. Even the plague in Chang’an is turned into life-saving soup with a secret System recipe, and the people build shrines to him in the streets, calling him a living Bodhisattva!
From a “transparent prince” suspected by the Crown Prince to the court’s resident idea man, he dares to discuss “commercial reform” with Li Shimin in the imperial study, take an embassy to Tubo for “cultural outreach,” and build modern irrigation works outside Chang’an, turning ten thousand mu of wasteland into fields yielding a thousand catties per mu. He gets creative with System missions: he can unlock imperial examination reforms so impoverished scholars can enter the Golden Hall, or set up food-processing workshops that fill the markets with the aroma of pastries. Even the Turkic khagan secretly sends people to learn how to use the Great Tang’s golden finger!
Lighthearted and silly, with no need to overthink things, this story is packed with satisfying political maneuvering and clever battles of wits. Watch this prince with a System plant technology, sell ideas, and build infrastructure among the red walls and green tiles, turning the Reign of Zhenguan into a thrilling story with cheats. When an ancient prince pulls out a “bundle of modern knowledge,” the court becomes a workplace, the palace a laboratory, and even Empress Zhangsun smiles and says, “Yi’er’s ideas are more wonderful than Chang’an’s poetry!” High energy from beginning to end, with no pitfalls and System rewards that never disappoint. See how Li Yi uses “sign-ins and troublemaking”
