Li Juntian came too late, and the Sui Dynasty was already empty; but it was too early, and Li Yuan was still pretending to be a loyal minister.
As a Sui minister, he was disloyal - he secretly cut off the canal grain route, forcing Yang Guang to patrol out of order, and made the court "both jealous and forced to rely on" Taiyuan;
As Li Yuan's son-in-law, he was unfilial - he gradually moved his military status, the craftsmanship of Jinyang Palace, and the secret accounts of the Hedong family into the "other department" under his own name.
Li Jing dared to accept the post with accusations; Fang Xuanling lamented that the Li family was "too weak to carry on a great cause", but he dared to negotiate terms;
Dou Jiande's old army, the remnants of Wagang, and the poor families in Guanzhong... As long as they are willing to hand over the hilt, he will give them officials, fields, and status.
Li Shimin gets stronger and stronger as he fights, but every time he looks back, he will find that his plans, his generals, and his food are always connected to Li Juntian's other courtyard.
Later historians wrote about him: "The name is Sui Chen, but he is actually stealing the country; relying on the Li family, he finally seizes Li Ding."
Li Juntian only smiled:
"You call him a traitor and a traitor - I call him: someone else should take charge of the world."
