In February 617, Yang Guang appointed Li Yuan as the ambassador of Hedong in Shanxi, the guardian of Taiyuan, and the palace supervisor of Jinyang, so that Li Yuan could seize the military and political power, and according to Yang Guang's order, Li Yuan ordered his eldest son Li Jiancheng to lead an army to recruit Zhen Zhai'er, the thief of Lishan, and the two armies were in Hexi County

In the Battle of the Bird and Mouse Valley, Li Jiancheng won a complete victory.

Li Yuan reorganized the Northwest Army led by Duan Zhixuan into the Xuanjia Army, and ordered his second son Li Shimin to lead it to conquer other rebel armies, and in the process of conquering the rebel army, Li Yuan's army also increased rapidly.

This year, there were more and more troops in the world who rebelled against the Sui, and Li Shimin, who was quite ambitious, asked Li Yuan's close friends, Jinyang to order Liu Wenjing, and Pei Lian, the deputy supervisor of Jinyang Palace, to discuss.

Li Shimin said: "And today, the rebel army is everywhere, invincible, and Your Majesty is partial to Jiangdu, what should we do?" ”

They are all old and refined guys, hearing Li Shimin say this, how can the two of them not know what he is thinking?

After being silent for a while, Liu Wenjing said, "I don't know what Gong Li thinks?" ”

"My father has been hesitant to remember that he and Yang Guang are cousins, but the general trend of the world is changing rapidly, how can we do nothing?"

Pei Lin said: "I have a plan to help Li Gong make up his mind as soon as possible." ”

Liu Wenjing said: "What's the plan? ”

Pei Lin said: "When Yang Guang goes south, the beauties of Jinyang Palace will have time to take them away in the future, so they will choose a few of them with good looks and serve them while Li Gong is drunk, so that Li Gong will have to rebel if he doesn't want to." ”

Liu Wenjing stroked his palm and said: "This plan is feasible, without further ado, the two of us will ask Gong Li to come to Jinyang Palace to drink tonight, and the second son will assist from the side." ”

The three of them agreed that Liu Wenjing would personally go to the house to invite Li Yuan. Li Yuan saw that his friends invited him, and he did not doubt him, so he happily went.

Li Yuan, Liu Wenjing, and Pei Lin drank and worked in Jinyang Palace, and soon they were all drunk and unconscious, Pei Lin took the opportunity to let Liu Wenjing take him away, and recruited eight palace maids to accompany Li Yuan.

The next day, Li Yuan woke up and saw that he was lying on the dragon bed in Jinyang Palace, and shouted in his heart: "Pei Lin and Liu Wenjing misunderstood me." ”

hurriedly packed up his makeup, and ran towards the outside of the palace, the palace gate opened, and he saw Pei Lian, Liu Wenjing, and Li Shimin waiting there early, and Li Yuan was furious.

Pei Lin hurriedly explained the strategy of the three of them, and said: "Arrange for the palace maid to serve, after the matter is exposed, you will be killed, I am doing this to persuade you to make up your mind to raise troops." ”

Li Yuan was still furious and said: "I treat you and you like brothers, and you and you have indeed framed me like this, so I will order someone to take you and others to see the officials, and I will go to Jiangdu to ask Your Majesty for guilt in person." ”

Li Shimin hurriedly knelt down and said: "Father is angry, don't care about the affairs of the two adults, and ask my father to take the child and send it to the official." ”

Seeing Li Shimin's tearful persuasion, Li Yuan said decadently: "You are my son, the son is not the fault of the father, how can I bear to send you to the official?" You get up, this matter has to be discussed in the long run, I have to write to ask your second uncle, after all, almost all the soldiers and horses in our hands are given by your second uncle, people can't forget their roots, and as long as you don't have a second uncle, it is impossible to completely exterminate the Sui Dynasty, and the people in the room should be locked up for the time being, don't harm their lives, and wait until the matter is settled. ”

Seeing that although Li Yuan insisted on being loyal to the Sui Dynasty, he no longer firmly opposed the move, the three of them were overjoyed.

Li Shimin has been taken by Gao Buer since he was a child, and he deeply admires Gao Buer's deep understanding of righteousness, if Gao Buer wants to take the world, he Li family should obey, if Gao Buer is not here, then he will help the Li family to win the world, just by virtue of him sending nearly 30,000 elite troops to help, so Li Shimin quickly sent the letter according to Li Yuan's meaning.

It was already May when Gao Buer received Li Yuan's letter, and at this time he was preparing to lead the army south, and when Xiao Yumei handed over the letter to him, he was having dinner with the three ladies, and showed Li Yuan's letter to the three ladies.

Xiao Yumei said: "I didn't expect Tang Guogong to be impatient. ”

Dugu Binglan said: "The general trend of the world is like this, and it will be wiped out if it is not fighting, but looking at the world, if the husband wants to take the world, it seems to be the most likely." ”

Su Xiaoxiaojiao smiled: "I'm afraid that my husband has no intention of this world." ”

Gao Buer laughed and said: "Those who know me, little miss, I am busy with everything, I just hope that the world will be peaceful as soon as possible, and let people have a peaceful birthday in two days. ”

Xiao Yumei said: "Then how to reply to the letter?" ”

Gao Buer said: "Just one sentence, build a high wall, accumulate grain, slowly become the king, learn from the old things of the Cao family, occupy Chang'an first, and then take the Central Plains." ”

Li Yuan, who was anxiously waiting in Taiyuan, received a letter from Gao Buer in early June, and was overjoyed and ordered Li Jiancheng, Li Shimin, and Li Yuanji to go to Jinyang, Hedong, and Longxi to recruit troops and prepare for trouble. Li Shimin, who went to Longxi, went to Zhangye and took the 20,000 war horses given by Gao Fuji.

Wang Wei and Gao Junya, deputy guards of Taiyuan, saw that Li Yuan was recruiting troops everywhere and suspected that Li Yuan was going to rebel, so they plotted to trick Li Yuan's father and son into praying for rain at the Jin Temple and get rid of them.

But now the rectification of Taiyuan is under the supervision of the intelligence organization established by Gao Buer, and soon the plan of the two was learned by Li Yuan, Li Yuan was shocked into a cold sweat, because he had promised the two to pray for rain, and he was even more grateful to Gao Buer, and immediately sent troops to arrest Wang and Gao, and framed the two of them for secret communication with the Turks.

So Li Yuan was in front of Jinyang Palace and beheaded Wang Wei and Gao Junya to sacrifice the flag. In July, Li Yuan officially announced the launch of troops against the Sui in Taiyuan, with more than 40,000 troops. Ordered the eldest son Li Jiancheng and the second son Li Shimin to go south in two ways to capture Chang'an.

Li Jiancheng, Li Shimin, and the two armies successively broke through the Sui Yingyalang general Song Laosheng who defended Huoyi, and surrounded the Sui general Qu Tutong who defended Hedong, and then quickly advanced to the southwest.

Because Yang Guang went south, he almost swept up all the Sui troops in the pass that had the strength to fight, and all that was left was just a city gate, and even the bandits were powerless to exterminate, so how could they resist the Li family's army. At this time, most of the forces of the Sui army, under the leadership of Wang Shichong, fought fiercely with the Wagang army in Luoyang, and there was no time to look north.

It only took more than ten days for Li Yuan and his son to lead troops to attack Chang'an, supporting Yang Yu as the emperor and changing the Yuan Yining to Emperor Sui Gong. Emperor Gong enshrined Li Yuan as the king of Tang, the prime minister, and Shang Shuling, overseeing all important military and political affairs, conquering the world on behalf of the emperor, and named Li Jiancheng as the prince of Tang, Li Shimin as Jingzhao Yin, Qin Guogong, and Li Yuanji as Qi Guogong.

When the news reached Jiangdu, Yang Guang roared wildly and scolded Li Yuan: "I am ashamed to be a son of man, and I regret that I didn't kill his family in the first place." ”

The roaring sound lingered all night over the Jiangdu Palace.
