General: Great Qin Dynasty Bureau

In 212 BC, the young master Jiang Lu woke up from a pool of blood in the execution ground and was reborn as his 17-year-old self. This coincided with his eldest brother Fusu leaving Beijing for Shangjun. As a prince who had been sentenced to death, he returned with the memories of future generations, knowing full well that Shaqiu's edict would cause the Qin Dynasty to collapse four years later. Hu Hai's stupidity, Zhao Gao's ruthlessness, Li Si's vacillation, and the upcoming Dazexiang uprising have laid a dragnet. This time, Jiang Lu hid his edge: he used three water conservancy strategies to gain the attention of the First Emperor, secretly plotted the border defense plan, and planted spies in the Zhao Mansion; he asked someone to send a secret letter to warn Fusu, and used the Huns' movements to clear out the traitors in the border army, and recruited Han Xin and Xiao He to accumulate strength. When the First Emperor died in the sand dunes, Zhao Gao suppressed the imperial edict and activated the "Xuanniao" intelligence network. He intercepted the false imperial edict, joined forces with Meng Yi and Li Si, and helped Su put down the rebellion with 30,000 frontier troops. Fusu ascended the throne and changed the Yuan Dynasty to "Yongshi", and made the general Lu Wanyanhou. He assisted the new emperor in reducing corvee labor and revising laws, introduced Confucian scholars into the court but maintained the foundation of Qin law, sent Han Xin to attack the Xiongnu and Zhao Tuo to defeat Baiyue, creating "Yongshi Zhongxing". On his deathbed, Fusu told the secret of immortality and took Lu as the head of the clan to protect the Qin Dynasty for hundreds of years. He put down rebellions, promoted scientific and technological innovation, implemented grace orders, and witnessed the changes of several emperors. At the top of the city of Xianyang, black birds flew by, guarding not only the dynasty, but also another possibility of Chinese civilization - no conflict between Chu and Han, no king Mang usurping the Han, only the jade seal of "eternal foundation" passed down from generation to generation.
