After Tang Gaozu acceded to the throne, Li Jian was the prince, Li Shimin was the king of Qin, and Li Yuanji was the king of Qi. Of these three people, Li Shimin contributed the most. Taiyuan arise, is his idea; In the next few battles, he also made the greatest achievements. Li Gonggong was inferior, and only because he was the eldest son of Gaozu did he get the position of Prince.
Li Shimin is not only brave and resourceful, but also has a group of talented people. Du Ruhui, an expert in the Qin Dynasty, is known as the Eighteen Bachelor. Famous generals such as Qin and Cheng are all brave generals in martial arts. When the Prince made achievements, he knew that his prestige was inferior to that of Li Shimin, and he was jealous, so he joined forces with his younger brother Wang Qi Yuanji to crowd out Li Shimin.
When Cheng Jian and Yuanji know that Tang Gaozu likes some concubines, they often give gifts in front of them to please them. Li Shimin has not done so. After Li Shimin pacified the eastern capital, some concubines privately asked Li Shimin for the treasures of Sui Palace. They also worked for their relatives, but Li Shimin refused. Therefore, concubines often speak well of the prince and the shortcomings of the king of Qin in front of their great-grandfathers. Tang Gaozu listened to his favorite concubine and gradually alienated Li Shimin.
Li Shimin made great contributions, and Yuanji became more jealous and tried every means to get rid of Li Shimin.
On one occasion, Li Shimin was invited to the East Palace for a drink. Shimin had a few drinks and suddenly felt a stomachache. When someone helped him home, he felt pain and vomited blood. Li Shimin knew it must have been poisoned in the wine, so he quickly asked for medical treatment and finally got better.
Built, Yuanji wanted to harm Li Shimin, but he was afraid that Shimin's men had more brave generals and really began to take advantage, so he wanted to buy them off first.
Jiancheng privately wrote a letter to Wei Chijingde, the brave general under the king of Qin, saying that he wanted to make friends with Wei Chijingde and sent a car full of gold and silver to Wei Chijingde.
Wei Chijingde said to the messenger, I am a subordinate of the King of Qin. If I associate with the prince privately and am half-hearted about the king of Qin, I will become a greedy villain. What's the use of such a person to the prince? With that, he returned a car full of gold and silver intact.
Wei Chijingde refused to build it, and he was angry. That night, Yuanji sent an assassin to Wei Chijingde's house to assassinate him. Wei Chijingde had anticipated that when it was completed, they would not let him go. At night, deliberately open the door. The assassin sneaked into the yard and peeped through the window. He saw Wei Chijingde lying on the bed with a spear beside him. The assassin knew his fame long ago, and he was afraid that he would be on guard and didn't dare to do it, so he secretly came back.
After the completion, one plan of Yuanji failed and another plan was born. At that time, the Turks invaded the Central Plains and suggested to Tang Gaozu that Yuanji should replace Li Shimin's Northern Expedition. After appointing Yuan Ji as commander-in-chief, Yuan Ji demanded that the elite soldiers of Qin, Qin, Cheng and Qin be placed under Yuan Ji's command. After they plan to transfer these soldiers, they can let go of killing Shimin.
Someone reported the secret plan to Li Shimin. Shimin felt that the situation was urgent and quickly consulted with his brother-in-law, Sun Chang Wuji and Wei Chijingde. They all suggested that Li Shimin take the initiative. Li Shimin said: It is never a decent thing for brothers to kill each other. Or wait for them to move out, and then we'll deal with them.
Wei Chijingde and mowgli are very worried, saying that if Shimin doesn't start work, they don't want to stay in Qin and die in vain. Seeing that his men were very determined, Li Shimin made up his mind.
That night, Li Shimin entered the palace and complained to Tang Gaozu about how the Prince and Yuanji murdered him. Tang Gaozu promised to wait until tomorrow morning, called the three brothers into the palace together, and personally asked.
The next morning, Li Shimin told Sun Chang Wuji and Wei Chijingde to take a good soldier and ambush at Xuanwu Gate in the north of the palace, just waiting for Yuanji to enter the palace.
Soon, Cheng Jian and Yuanji came riding the Xuanwu Gate of Ma Chao. When they arrived at Xuanwu Gate, they felt that the surrounding atmosphere was a little abnormal and became suspicious. The two men turned their heads and prepared to go back.
Li Shimin rode out of Xuanwu Gate and shouted, Your Highness, don't go!
Yuanji turned around and picked up the bow and arrow around him, trying to shoot Shimin, but he couldn't even pull the bowstring in panic. Li Shimin nimble, shoot an arrow, the first arrow shot dead Jiannu; Then, Wei Chijingde rushed out with seventy cavalry, and Wei Chijingde shot down Yuanji with an arrow.
When the soldiers of the East Palace and Qi Wangmi heard that something had happened to Xuanwu Gate, they all went out to attack the soldiers of Qin Wangmi. Li Shimin ordered the soldiers to resist while sending Wei Chijingde to the palace.
Tang Gaozu is waiting for three people to appear in court in the palace. Wei Chijingde rushed into the palace with a spear in his hand and said: The prince and the king of Qi rebelled, and the king of Qin killed them. The king of Qin, afraid of disturbing your majesty, specially sent me to protect him.
Gaozu knew that something had happened outside, and he was so scared that he didn't know what to do.
The prime minister, Xiao R, and others said: He Yuanji has no credit, is jealous of the king of Qin, and uses tricks. Now the king of Qin has wiped them out, which is a good thing. Your majesty handed over the affairs of state to the king of Qin, and everything would be fine.
At this stage, it is useless for Tang Gaozu to object. Just listen to the words of the ministers, announce the completion of the charges against Yuanji, and order all the soldiers in the imperial court to be under the command of the king of Qin. Two months later, Tang Gaozu gave way to the king of Qin and became the emperor's father. Li Shimin acceded to the throne, that is, Emperor Taizong.
