Li Jiancheng kowtowed, and when he was about to faint to death, Li Yuan was worried that his beloved eldest son would kowtow to death in front of him, and he couldn't bear it, after all, this baby had his essence and blood flowing on his body.

When Li Jiancheng was in pain, the emperor's father finally shouted to stop, and he stopped without hesitation. But Li Yuan's anger did not subside, and he locked him in a tent that night, and sent him like a beggar, so that he could look at him like a prisoner.

Then, Li Yuan ordered Si Nongqing Yu Wenying to summon Yang Wengan.

Yu Wenying rushed to Gyeongju and told Yang Wengan in detail about the prince's admission of his mistake.

Yang Wengan is a persistent man, and if he wants to go to the dark, he must stick to the matter of raising troops to the end, otherwise he will be sorry for his "dream".

On June 24, the seventh year of Wude (624), Yang Wengan embarked on the road of his "dream" - to raise an army against the Tang Dynasty.

When the news of Yang Wengan's army was reported to Renzhi Palace, Li Yuan was so angry that his heart almost exploded, and Yang Wengan's army meant that the mastermind behind Yang Wengan's army was Li Jiancheng.

This earth-shattering reality is like a hammer hitting the door of Li Yuan's head, not abolishing the prince, and he is not angry.

While Li Yuan sent people to crusade, he discussed countermeasures with Li Shimin.

Li Yuan promised Li Shimin: You go and destroy Yang Wen, I will abolish Li Jiancheng and make you the prince.

- What a temptation!

With this charming temptation, Li Shimin led his troops to clean up Yang Wengan.

Yang Wengan is really a short-lived man, and before the god of war Li Shimin arrived, he was killed by his subordinates. At least to live, to fight Li Shimin, and to die in the hands of this strong enemy, it is much more glorious!

Yang Wengan's only record in raising troops was to send troops to occupy Ningzhou.

Li Shimin effortlessly leveled Yang Wengan, and was ready to go back to be the prince, but unexpectedly, Li Yuan's words were not counted, and Li Jiancheng was asked to return to Beijing to continue him as the prince, and treated the previous promise to Li Shimin as if he had never said it, but blamed the two brothers for not getting along, making outsiders laugh. In order to protect the calf, Li Yuan pulled out three men who had poured blood mold to vent his anger, and blamed the fight between their two precious sons on Wang Qi of the Prince's Mansion, Wei Ting and Du Yan of the Qin Prince's Mansion, and after a period of reprimand, exiled them.

Li Yuan exiled people in such a way that he disregarded people's feelings, and he could be regarded as beating the two brothers fifty boards each.

However, an old ginger like Li Yuan should not be so stupid, go back on his word, not think about the safety of the society, blindly trust the prince too much, and speak to Li Shimin, which is debatable in the historical records.

In the Tang Dynasty, a man named Liu Kui wrote a book called "Jiahua of the Sui and Tang Dynasties", which contained the sentence "people sue the East Palace in vain", which Sima Guang quoted when he wrote "Zizhi Tongjian".

There is a bold speculation that the so-called Yang Wengan's army was a conspiracy planned by Li Shimin - it is more likely. Li Jiancheng sent armor to Yang Wengan is true, but it is not a rebellion, Li Shimin learned this information through the undercover agent who was planted next to Li Jiancheng, so he seized this handle and made an article about the prince and Yang Wengan conspiring to rebel, the purpose is to wait for the prince to be convicted of rebellion, Li Yuan deposed him as the prince, so that the crown prince would belong to him.

It's worth the risk, and it doesn't seem like much effort.

Unexpectedly, Li Yuan knew the truth, so he continued to let Li Jiancheng be the prince and alienated Li Shimin. once promised to make Li Shimin the crown prince, but there is no door.
