I Have Been Living in the Tang Dynasty for a Long Time

Shen Yan, a researcher who is deeply involved in the history of the prosperous Tang Dynasty, accidentally traveled to the end of the troubled times of the late Sui and early Tang Dynasties, which coincided with the founding of the Tang Dynasty. He awakened to eternal life in this troubled world. Having read the rise and fall of the Tang Dynasty over three hundred years, he understood the destiny of this new and prosperous world better than the world. The royal family is bleeding, the heroine usurps the Tang Dynasty, the powerful ministers are disrupting the government, and the feudal towns are tearing apart the soil. The Tang Dynasty, which was in its prime, will eventually fall into the abyss step by step. Troubled times have arisen again, and mountains and rivers thousands of miles away are devastated. Unwilling to witness the same mistakes of destruction again in the prosperous times of the ages, Shen Yan used immortality as his salary, his power as his blade, and his time as his bureaucracy, hibernating to mend the sky from generation to generation. In the early years of Zhenguan, he was a minor official in Hongwen, filling the loopholes in national policy, stabilizing the foundation of the prosperous era, and helping Li Shimin create the long song of Zhenguan; During the reign of Emperor Gaozong, he incarnated himself as a censor who directly admonished the censor, checked and balanced powerful ministers and relatives, and nipped the buds of chaos in the harem; During the turbulent times of Wu and Zhou, he hid in the countryside to administer government and bring peace to the people, retaining the firepower of the Tang Dynasty and waiting for the mountains and rivers to return to the Tang Dynasty; During the prosperous age of Kaiyuan, he returned to the court as an adviser, purged traitors, dismantled vassal towns, and killed the Anshi Rebellion in the cradle. Kings and ministers changed, and the years went by. Fang Du, Wei Zheng, Li Jing and Di Gong, and famous officials knew and worked with him from generation to generation. Through the ages, the emperors relied heavily on him and regretted it, but no one knew that this capable man who saved the Tang Dynasty from collapse several times was always the same person. Everyone in the world lamented that the Tang Dynasty was an unparalleled prosperous age, but Shen Yan was the only one who knew that there was no eternal prosperous age in the world. He was the only one who watched the heroes come to an end and guarded the mountains and rivers for eternity.
