Sui and Tang Dynasties: Inherited Overlord, Empress Xiao Praised Me for Being Too Fierce

[Repentant Marriage Beginning] + [Contact Li Er] + [Rebuild the Sui Dynasty] + [Pull down the Siyi] Yang Zheng accidentally traveled to the Sui Dynasty in the twelfth year of Daye. He originally wanted to go south to Jiangdu to join Yang Guang, gradually establish his own power with Yang Guang's support, and finally embark on the road to conquer the world. But before he left, he unexpectedly fell in love with Li Yuan's sixth daughter, Li Xiuyan. In order to win the beauty, he finally gave up his dream of competing in the world and became Li Yuan's staff. Relying on his understanding of the history of the Sui and Tang Dynasties, Yang Zheng repeatedly made extraordinary achievements and made great contributions to the Li family. For this reason, Li Yuan promised to officially marry Li Xiuyan to Yang Zheng as long as the Li family pacified Guanzhong. But on the eve of Li Yuan's ascension to the throne and proclaiming himself emperor, Yang Zheng openly regretted his marriage because of his humble background. Only then did Yang Zheng realize that the so-called love between him and Li Xiuyan had always been a scam against him. Faced with the Li family's betrayal, Yang Zheng accidentally awakened the troubled times selection system. Not only did he gain the military power of Xiang Yu, the overlord of Western Chu, but he also learned that he was the grandson of the deposed prince Yang Yong, a member of the Sui royal family. Now that there is a system, Yang Zheng can no longer tolerate Li Yuan. In the early morning before the enthronement ceremony, he kidnapped Li Jiancheng, rescued Li Jing from prison, castrated Li Yuanji in front of Li Yuan and ministers, and then walked away... In the Sui Dynasty, if he was there, it would not be destroyed. And the one who destroyed the Tang Dynasty must be Yang Zheng.
