Future scientist Yu Dou takes the intelligent robot "Junping", the robot dog "Big Ears" and the super AI "Waiqi" to travel to Xianyang of the Qin Dynasty in 212 BC. In order to sow the spark of literature, he relied on future technologies such as "World Map", "Photolithography" and "Rejuvenation Yin" to shock the court with his "auspicious" name, and was awarded the title of "Doctor of Tiangong" by Qin Shihuang. In Lanchi Palace, he improved the curved shaft plow to help farmers and mulberry trees, used science and technology to solve the plague crisis, optimized ordnance to defend the border, and even revolutionized the industry of the Qin Dynasty with the technique of "light refining". However, the Zhao Gao Group is secretly watching, and the power game in the court follows closely. Yu Dou uses science and technology as his blade to cut through the thorns in the long night of the empire, and uses the green jade hairpin as a bond of faith. He vows to let the spark of the future ignite the prairie fire of civilization and write an epic of civilizational collision across time and space.
