Yuqinglu

In the spring of 2026, back-end engineer Li Qingyun touched the bronze sacred tree during team building in Sanxingdui, and was drawn into the Qin Dynasty in 226 BC by the blue light. He was unarmed, carrying only a laptop with no battery, a strange bookmark, and an engineer's mindset. In this era where people without an ID card are considered illegal, he relied on his troubleshooting instinct of "collecting information first and then locating the root cause" to step by step from a prisoner in the Tingwei Mansion to the King of Qin Yingzheng. He cannot make guns, is not good at riding horses, and vomits blood when he sees it. But his battlefield is between the court and the market - using the "index system" to transform the Tingwei Mansion case files, using the "decision tree" to dismantle the strategies of the Six Nations, and using the "standardized process" to improve the Qin army's logistics. When the civil and military forces of the Manchu Dynasty debated whether to attack Zhao first or stabilize Han, he helped Ying Zheng see clearly the true cost behind each choice. But he gradually discovered that time travel was no accident. The bronze sacred tree is a cross-time and space node left by ancient civilization. The word "" on the wall of the cell hints to the forerunners. The secret technique of twins passed down in ancient Shu can actually make people "become" another person. When Ying Zheng's body is on the verge of reaching its limit, Li Qingyun must use his body as a substitute to complete the final journey for this eternal emperor. From the programmer who laughed at himself that "everything is the best arrangement" to the imperial architect who conspired with the King of Qin; from the silent slave rescued from the wooden cage in the market to the "Yuqing Empress" Xuerou who is in charge of the intelligence center. This is a long saga about the penetration of knowledge into the times and the coexistence of rationality and iron-bloodedness. ——"I'm not here to change history. I was just dragged in and found that this system... Can be optimized a little bit more."
