After Time Travel, He Inexplicably Became the Prince-In-Law of Various Dynasties.

A bizarre car accident caused Xu Xian in the 21st century to travel through time and space, bind the "Emperor System", and obtain an imperial manor that can connect various dynasties. In order to extend his life and unlock the modern passage, he was forced to embark on a journey of historical revision that spanned thousands of years - leveraging China's destiny with a mortal body and sewing up the dynasty's rifts with modern wisdom. In the Xianyang Palace, he pointed out Xu Fu's Jindan scam and joined hands with Ying Zheng to build the Daqin Lantian Special Zone, creating the first feudal industrial model with cement roads and hybrid rice technology. He also used the ingenious plan of "abdication of destiny" to promote the bloodless inheritance of the First Emperor and Liu Bang. When he took the two princesses into his arms, he quietly rewrote the fate of the Second Emperor of Qin to die. With the knowledge of the Qin Dynasty, he went to Bianliang to break the deadlock between the Liao and Song Dynasties: he established an autonomous region to resolve ethnic vendettas, used economic warfare to conquer Yanyun without bloodshed, and used the power of Liangshan heroes to eliminate the root of the Jurchens a hundred years ahead of schedule. When the two princesses of Song and Liao held red silk together, the Great Steel Wall had already been erected across the grassland in northern Xinjiang. In front of the Xuanwu Gate, he transformed into a counselor in white, used the imperial examination system to dismantle the five surnames and seven hopes, and used penicillin to save the life of Empress Changsun. During the Anshi Rebellion and the war, he and Wei Zheng's daughter laid a dragnet and condensed the charm of the prosperous Tang Dynasty into a rainbow that will never fade. Deep in the Weiyang Palace, the Han cavalry was following the Hexi Corridor railway he laid, turning the Hun royal court into historical dust. When Cao Cao established the system of three provinces and six ministries at his suggestion, when Zhu Yuanzhang saved his wife and children through the epidemic prevention manual he left behind, when Zhu Di's treasure ship carried a steam engine across the ocean - the Chinese dragon that had been dormant for thousands of years finally raised its head. The essence of civilization drawn from the Qin, Han, Tang and Ming dynasties
