Sui and Tang Dynasties: I Asked You to Take the Back, Not to Save the Sui Dynasty

AD 617, the thirteenth year of the Sui Dynasty. Yang Tong traveled through the late Sui Dynasty and became the grandson of Yang Guang, the great Sui and Yue king. At this time, the world was rebelling against the king. Emperor Yang Guang of the Sui Dynasty led his ministers and concubines to take refuge in Jiangdu. Leaving Yang Tong behind to guard Luoyang, Yang Tong became a real backer. There are Wagang Army and Dou Jiande in the east, and Li Yuan and Liu Wuzhou are about to rebel in the west. There is Wang Shichong plotting to seize power. At the moment of crisis, Yang Tong activated the Wuhun system to crush everyone in terms of force, command, intelligence, and politics. In the first year of guarding Luoyang, Yang Tong led the army to level Wagang, recruited famous generals, destroyed Liu Wuzhou, captured Dou Jiande, and surrendered to Luo Yi. In the second year, Yang Tong defeated Yu Wenji, rescued Yang Guang, and destroyed all the kings in the south. In the third year, Yang Tong defeated the Tang army, defeated Li Yuan and Li Shimin, and occupied Guanzhong. In the fourth year, Yang Tong set foot in Liaodong, defeated Pyongyang and destroyed Goguryeo. In the fifth year, Yang Dong destroyed the Turks, the horse trampled the royal court, and the wolf was granted the title of Xu. In the sixth year, Yang Tong wiped out the aristocratic families and clans in the Sui territory, so that the Sui Dynasty would no longer be disturbed by internal worries! A few years later, when Emperor Yang Guang returned to Luoyang, he found that the territory of the Sui Dynasty had expanded dozens of times! Yang Guang said ashamedly: Dong'er, I just kept you in Luoyang as a backup, not to save the Sui Dynasty!
