The imperial examination system brought many talents to Emperor Wendi of Sui Dynasty, and these talents did a lot of work for him, so Emperor Wendi attached great importance to talents. And Tang Gaozu was the talent that Emperor Wen of Sui Dynasty thought. Why do you say that? Because when Emperor Wendi of Sui met Li Yuan for the first time, he thought he was destined to be an extraordinary person. Emperor Wendi of Sui Dynasty still had a strong eye for people. Hiring Tang Gaozu helped him a lot, but it happened that Emperor Wendi, who contributed to him, always wanted to kill him.
Because during the reign of Emperor Wendi of Sui Dynasty, he had a nightmare, dreaming that his home was replaced by others, and the name of the person who replaced his Yang family had water. Emperor Wen of Sui's first thought was Tang Gaozu, and Emperor Wendi of Sui was going to kill Tang Gaozu. When Tang Gaozu found out, he turned to his aunt, the lonely wife of Emperor Wendi of Sui Dynasty. Emperor Wendi and his wife are very loving.
So that when Emperor Wendi was emperor, he was still the only wife. When the lonely Galois knew that Emperor Wen of Sui was going to kill the loyal minister because of one of his dreams, he and his nephew Tang Gaozu would certainly protect him without saying anything. Tang Gaozu also knew that he must be a thorn in the side of Emperor Wendi, so he simply lived in seclusion and didn't care about state affairs, so the idea of Emperor Wendi killing Tang Gaozu slowly disappeared.
This also laid a lot of foreshadowing for Ethan's future growth.
