A bolt of lightning split time and space, and the social animal Wang Chao traveled to the Xianyang Palace of the Qin Dynasty in 210 BC, and accidentally bound to the "Universal Unification System". With the mission of helping Qin Shihuang live forever and conquer the world, he came with super-era technologies: the Quyuan plow revitalized farming, improved steelmaking techniques to forge sharp weapons, scientific plans helped Ying Zheng get rid of aging, and gunpowder and repeated crossbows revolutionized the war situation.
Within three years, he assisted the Qin Dynasty in pacifying the Xiongnu and subduing Baiyue, filling its granaries with high-yielding crops, sailing far away with advanced ships, gradually conquering overseas countries, and completing the great cause of unifying the earth. When the dragon flag of Xianyang Palace is planted in every inch of the world, the immortal Ying Zheng sets his sights on the sea of stars, and Wang Chao's system interface unlocks the coordinates of the universe - this hegemony that began in the Qin Dynasty will eventually span the stars and create an empire legend that spans the world.
