Li Yuan was furious when he heard the report and ordered the murderer to be strictly investigated. In the end, the murder case was solved, and the two killers were Dingzhou assassin Shi Duguxiu and his younger brother.

Two years ago, their father, Dugu Ji, a doctor under the emperor and the lord of Huangtai, was beheaded by Wang Shimanmen because of a conspiracy to contact the Tang army to attack the eastern capital; Now, with little defense and resistance, they have succeeded in avenging their father. When Emperor Li Yuan learned about it, he only removed Dugu Xiu from his official position.

Wang Shichong's son Wang Xuanying and other men in the family were all killed by the Tang Dynasty on charges of rebellion when they walked halfway.

After solving the Wang Shichong family through tortuous means, Emperor Li Yuan finally fell to the ground in his heart.

Li Yuan thought that the world had been pacified and the four seas were unified, so he announced an amnesty for the world; However, he still ordered to pursue Dou Jiande's remnants, and after arresting him, he was exiled to the frontier.

Sun Fujia, the secretary of the imperial history, wrote a letter of advice: "Confucius has a saying, soldiers and food can go, but faith cannot go, since Your Majesty has announced an amnesty to the world, and continues to exile Dou Jiande's subordinates to the frontier, is it against the original intention, so that your subordinates do not know which of your edicts shall prevail?" Besides, even Wang Shichong was treated leniently, not to mention Dou Jiande's remnants? The minister thought that all those who had been arrested should be released. ”

Li Yuan accepted Sun Fujia's suggestion, but did not cancel the previous edict. Officials across Hebei continued to hunt for Dou Jiande's generals.

After Dou Jiande was defeated, his generals returned to the countryside with the wealth they had accumulated over the years. The local officials of the Tang Dynasty wanted to draw fat from it, so they tried every means to borrow the provisions of the law to deal with them, and after they were arrested, they were sometimes tortured, which made Dou Jiande's old generals panic and uneasy. Dou Jiande's main generals, Fan Yuan and Wang Xiaohu, were in Zhouzhou, and they planned to secretly flee to other places with their family property, but the government was very eager to pursue them, so they had to flee to Beizhou.

At this time, they learned that the imperial court had recruited Dou Jiande's old generals Fan Yuan, Dong Kangmai, Cao Zhan and others, so they couldn't sit still.

"It's unfair, it's so unfair!" The generals sighed to each other and said indignantly, "Wang Shichong took Luoyang and surrendered to the Tang State, but his generals Duan Da and Shan Xiongxin were killed. When we get to Chang'an, we will inevitably be beheaded! In the past ten years, we have been through a hundred battles, and we should have died a long time ago, so why should we be greedy for life and fear death now? It's better to rise up and rebel! Look at our King Xia, he died so unjustly - he caught Li Shentong and Li Yuan's sister, and received them with guest gifts, but that Li Yuan caught King Xia and killed him! What a conscience! We are all people trusted by King Xia, and now if we don't rise up to avenge him, are we still human! Do you still have a face to live in this world? ”

"It's the other way around—even if we die, we're going to die with a bang!"

So the people decided to rebel. They burned incense for divination. The gods instructed them that if they were to serve the Liu clan as the master, they would be lucky. So they sneaked to Zhangnan to visit Dou Jiande's old general Liu Ya and told him about their plot.

Liu Ya refused to come out. "The world has just settled," he said to his former colleague, "and I intend to cultivate the fields for the rest of my life, and I don't want to raise any more troops!" ”

The people were furious, thinking that he had no conscience, and fearing that he had revealed a plot, and killed him.

Liu Heimin, the Duke of Handong who was sealed by Dou Jiande, also lived in seclusion in Zhangnan at this time; The crowd went to visit and told him of the conspiracy, and Liu Heimin happily promised to lead the rebellion. The people rejoiced; So they secretly recruited troops and wanted to rebel again.

When Li Shimin killed Wang Shichong, a major event also occurred in Jianghuai, and Du Fuwei and Li Zitong, the old enemies, finally had a fire.

Du Fuwei and his adopted son Wang Xiongdan led 30,000 men to attack Li Zitong, and they confronted each other at Qingsong Ridge. Du Fuwei saw that Li Zitong had been scared by the Great Demon Kingdom, and now he was very inward-looking.

They sent men to make more of them, and at night they set up false lights, trying to create the illusion of an army of hundreds of thousands. It may be that the last night attack left a serious psychological shadow, Li Zitong actually burned the camp tent by himself and retreated overnight. Wang pursued to the city of Hangzhou, Li collapsed, Li Zitong surrendered, and Du Fuwei monopolized Jianghuai.

After eliminating Li Zitong, Du Fuwei sent Wang Xiongdan to attack other independent forces in Jianghuai. Soon swept them away in one fell swoop and became the overlord of Jianghuai.

Of course, Li Tang could not let a new opponent grow up, and at this time, Li Shimin had just defeated Wang Shichong, so he took the opportunity to show off his military might with the border of the Great Military Road and Jianghuai.

At this time, Du Fuwei was hit and no longer had the ambition he had in the past, and the struggle for power in the family's auxiliary Gongyou was becoming more and more intense, and he was frightened by Li Shimin, so that he understood that the only thing that could still pose a threat to Li Tang was himself.

Du Fuwei naturally understood Li Shimin's intentions, and was very uneasy in his heart, worried that he would become Li Tang's next target; Finally disheartened, I decided to leave the picks and quit.

So Du Fuwei suddenly made a decision, and simply wrote to Li Yuan and asked to enter the court. Li Yuan was naturally happy after receiving the report and approved Du Fuwei's entry into the court. So Du Fuwei handed over the Jianghuai army to his son Wang Xiongdan, and he brought a few cronies to Chang'an to meet Li Yuan in July of that year.

Du Fuwei's initiative to offer loyalty made Li Yuan very satisfied, and at the same time, in order to make an appearance in front of the world, Li Yuan crowned Du as the crown prince Taibao, above the king of Qi Yuanji (that should be second only to Li Yuan, Li Jiancheng, and Li Shimin, the fourth person in the Tang Dynasty).

After Du Fuwei left, the Jianghuai army soon had a big mess. When the Jianghuai Army was founded, the supreme leader was Du Fuwei and Fu Gongyi, the two were friends since childhood, and when they grew up, they revolted together to fight the world, known as the friend of the neck, Fu Gongyou was older than Du Fuwei, Du called Fu Gongyou his brother, and the army called Fu Gongyou "Fu Bo", and the status of Fu was equivalent to Du.

But with the growth of power, under the lure of power, the friendship between the two finally cracked, Du Fuwei thought that the status of Fu Gongyi was too high and affected his leadership, so Du seized the military power of Fu Gongyi, and only let him hold the position of a high-ranking and powerless servant.

Fu Gongqi was unhappy about this, so he took the initiative to withdraw from the power struggle under the pretext of learning immortal art with his old friend Zuo Youxian, and usually ignored government affairs.

When Du Fuwei went to Chang'an, he handed over the government affairs to Fu Gongyi, and handed over the military affairs to his confidant Wang Xiongdan, and at the same time secretly ordered Wang Xiongtan to monitor Fu Gongyou. The friend of the past has now become the object of vigilance.

After all, Fu Gongqi is not a person who is willing to ambush, as soon as Du Fuwei leaves, he conspires with Zuo Youxian to launch a mutiny.

The only obstacle for Fu Gongyi is Wang Xiongdan, Wang Xiongdan, Du Fuwei's righteous son and favorite general, absolutely loyal to Du Fuwei, he holds the military power of the Jianghuai army, and it is impossible to succeed without getting rid of him mutiny.

So Fu Gongyou resorted to a counter-plot and forged Du Fuwei's handwriting to write a letter to Wang Xiongdan, in which he blamed Wang Xiongtan for having a bad heart for no reason.

Wang Xiongdan was a brave and resourceful general on the battlefield, but when it came to political struggle, he was not an opponent, and after receiving the letter, Wang was very sad, so he was sick at home and no longer involved in military affairs, and wanted to prove to Du with practical actions that he was loyal and had no intentions.

Wang Xiongdan's behavior was in the hands of Fu Gongyi, who took advantage of the situation to take over the Jianghuai army, and forged Du Fuwei's secret order, saying that he was mistreated in Chang'an and asked Fu Gongyou to raise troops to rebel.

With the appeal of Fu Gong Yi in the Jianghuai Army, coupled with Du Fuwei's secret order, the mutiny was very smooth, and the Jianghuai Army announced its independence from Li Tang in August of the sixth year of Wude, and Fu Gong Yi proclaimed himself emperor, the country name Song, and Zuo Youxian was the secretary of the military department.

Fu Gongyi sent someone to Wang Xiongdan's house to persuade him to submit, and Wang Xiongtan finally understood that he had been deceived, but the general trend had gone and could not be stopped. Wang Xiong was loyal to Du Fuwei, and sternly refused the persuasion of Fu Gongqi to surrender, and died in battle.

Li Yuan was furious when he heard this, so he ordered Li Xiaogong to be the chief and Li Shiji to be the deputy chief to lead Du Fuwei's military orders; There was also another righteous son who followed Du Fuwei, Ximen Junyi, to put down the rebellion of Fu Gongyou.

Ximen Junyi and Wang Xiongdan are also known as the Jianghuai Shuangxiong, although his martial arts are not as good as Wang Xiongdan, but the iron mask is selfless, and has always been Du Fu Weiwei to the task. And Ximen Junyi also did a very good job, once found that the violator was punished, regardless of his relatives.

The two armies faced each other, and Ximen Junyi urged the horse to the front of the battle and shouted: "Do you still recognize Ximen Junyi?" Why dare you rebel against the Governor? I've got the commander's order here! If you don't surrender, when will you wait? ”

When the Jianghuai army heard this, they were all shocked and hesitated; Some even laid down their arms and surrendered.

Fu Gongyou hurriedly ordered his descendants to step forward to maintain the formation and kill the rebels, but he didn't expect this time to provoke a mutiny, and the resistance was even more violent.

As soon as Li Xiaogong saw the big hand, the Tang army swarmed up and defeated the Jianghuai army. Now that Li Tang's army has just destroyed Wang Shichong and Dou Jiande, their morale is booming; It has the posture of Lao Tzu who is the first in the world.

The Jianghuai army encountered great changes one after another, and the military morale that was disturbed by Ximen Junyi before the battle collapsed for a while. Li Xiaogong saw that he was chasing and fighting all the way, and he didn't give Fu Gongyou any time to adjust.

The Tang army successively conquered Wuhu, Liangshan, Danyang and other places occupied by Fugongyi. When the Tang army arrived in Danyang, Fu Gongqi was afraid and fled with his troops, and the Tang army pursued behind.

When Fu Gongqi fled to Wukang, local farmers captured him and sent him to Danyang. Fu Gongyou knew that he could not escape death, probably unwilling to go on the road alone, Fu Gongyou revealed to Li Xiaogong, the commander of the Tang Army, that Du Fuwei was the mastermind of the rebellion, and there was a secret order as evidence, even Ximen Junyi, who came back this time, was also a rebel.

Li Xiaogong took the opportunity to trap Ximen Junyi, and with the death of this last general, the Jianghuai army disappeared. Li Xiaogong immediately reported to Li Yuan, saying that he found that Du Fuwei was the mastermind behind the rebellion, and the human and material evidence was complete, so Li Yuan took action to deprive Du Fuwei of his official title and confiscate his family.
