In the thirteenth year of the great cause, the situation in the world has changed greatly.

Li Mi received the Wagang army and captured the Luokou Cang, the big granary of the Sui Dynasty, and he opened the warehouse to release grain and help the victims, and had more than 100,000 troops for a time. The power is so great that it has the potential to annex the Central Plains.

Dou Jiande also conquered the city, successively eliminated the main army of the Sui Dynasty, and occupied the entire Hebei region.

Du Fuwei fought in Jianghuai and defeated the Sui Dynasty army.

The peasant rebel army gradually gained the upper hand in the conquest against the Sui army. The army of the Sui Empire was gradually exhausted by the rebel army, and the world gradually became divided in all directions.

In June, Yang Guangzhao ordered Pang Yu and Huo Shiju, who were stationed in Guanzhong, to lead the troops of the Guannei Prefecture to rush to the aid of Wang Shichong, the eastern capital of Luoyang, to jointly crusade against Li Mi.

Guanzhong City's air defense is empty!

Li Yuanju's eyes knew the world, and when he learned this information, he felt that the time was completely ripe to go south to Guanzhong.

Soon, Li Yuan ordered Li Shimin to lead 500 soldiers to ambush in Xingguo Temple, and designed a deception in his own meeting hall, eliminating Wang Wei and Gao Junya, who were watching him in one fell swoop, and thus gaining absolute control of Jinyang City.

Soon, Li Jiancheng, the eldest son of Li Yuan, who was far away in Hedong City, received a secret letter from his father and led all the clans of the whole family to Jinyang City to meet his father. So far, Li Yuan has been relieved of his worries.

Immediately afterwards, Li Yuan accepted Liu Wenjing's suggestion and formed an alliance with Shibi Khan, the overlord of Mobei who was strong in armor at this time.

He sent Liu Wenjing as an envoy to Mobei to make an appointment with Shibi Khan - "Tang Gong won the world, the land and population belonged to Tang Gong, and the wealth and silk returned to the Turks." Shibi Khan was overjoyed and promised to fully assist Li Yuan's plan to raise troops.

On June 14, Li Yuan set up the General's Mansion, made himself a general, appointed Pei Lin as Changshi, Liu Wenjing as Sima, Tang Jian and former Chang'an Lieutenant Wen Daya as the secretary, Wen Daya and his younger brother Wen Dayou were still in charge of secrets, appointed Wu Shi Tong as the armor Cao to join the army, Liu Zhenghui and Cui Shanwei from Wucheng, Zhang Daoyuan from Taiyuan to join the army for Hu Cao, Jiang Yan from Jinyang Changshangqi to join the army, Taigu Changyin Kaishan as the Fu Peng, Liu Zhenghui as the subordinate of the government, and Quan Hongshou, Lu Jie, Tian Deping and other officials.

Li Yuan divided the recruited soldiers and horses into the left and right armies, and the prince Li Jiancheng was the Duke of Longxi and the Governor of the Left Commander, commanding the three armies of the left; The second son, Li Shimin, was the Duke of Stew Huang and the governor of the right leader, commanding the right three armies; Li Yuanji is the Duke of Gu Zang and leads the Chinese army. The eldest grandson Shunde and Ying Yanglang generals Wang Changhuan, Jiang Baoyi, Liu Hongji, Dou Cong, Li Gaoqian, Yang Mao, Yangtun, Wei Jin and others were respectively the left and right commanders and deputy commanders. Chai Shao is the governor of the right leading army.

On the 18th, the Turkic Shibi Khan sent his pillar state Kang Sheli, Jiezhi, Rehan, special service, and high-ranking officials to send thousands of horses to Jinyang City for mutual trading, and promised to lend troops to Li Yuan. Li Yuan sent Liu Wenjing to return to the Turkic Khan's tent with Kang Sheli to contact the matter of borrowing troops.

In July, Li Yuan led 30,000 troops to hold a pledge meeting at the military gate, leaving Yuanji to guard Jinyang City, and the army marched south along Fenshui to Guanzhong.

At this time, the Wagang army gradually grew in the Central Plains, but at the same time, it also caused a crazy counterattack by the Sui army. Although the world is chaotic, the Sui Dynasty still has the name of the world, the main force of the Sui army still has considerable combat effectiveness, and the various separatist regimes are also holding each other back and watching each other, and there is no one who sits on behalf of the Sui and sits on the world.

At this time of change, Li Yuan adopted Liu Wenjing's strategy after careful consideration. The rebels raised the banner of "Ansui Room", first, to avoid making too many enemies, and secondly, to preserve their own strength to the greatest extent.

Everywhere the army passed, there were inscriptions all over the place - "Today, there are all kinds of obscene people, and the society is worried about overturning!" The government is losing day by day, and the people are in danger of dying! Zier Tang Gong, can't bear to hang Li Min upside down, and wants to help the community and correct the discipline. The chaos in the world is all caused by the ministers in charge and the government decrees are biased. When the rebels go south, they save the people from fire and water and restore peace to the world......"

Along the way, the people heard that Li Yuanxing had rebelled and signed up to join the army. In addition, Li Yuan has always had a high reputation, and the rebels from all walks of life also came to defect.

Although the army was intercepted by the famous general Qu Tutong of the Sui Dynasty in Hedong City, it could not be attacked for a long time. However, Li Yuan quickly adjusted his thinking, followed the advice of Xue Dading, a native of Fenyang, crossed the Yellow River to the west, and went south to Chang'an from Weibeiyuan.

The rebels in Guanzhong heard that Tang Gong Li Yuan had arrived, and they joined one after another. Li Yuan's daughter, Princess Pingyang, and her husband Chai Shao also gathered tens of thousands of horses and horses to converge.

In just two or three months, Li Yuan's team quickly grew to more than 200,000 horses.

In November of that year, Li Yuan conquered Chang'an City. He supported Yang Yu, who was thirteen years old at the time, as the emperor, and Yang Guang, who was far away in Jiangdu, as the emperor.

Li Yuan proclaimed himself prime minister, entered the Tang Dynasty, faked Huang Yue, made a festival, supervised all the military inside and outside, and gathered all the military and political powers in one.

The members of the team who followed Li Yuan to raise troops were all rewarded, and they actually had complete control of the small court in Chang'an.

Everyone obeyed Li Yuan's orders, and the emperor was just a puppet.

After Li Yuan came to power, he immediately began to implement a series of far-reaching policies. First, he announced that "the twelve articles of the law with the people will eliminate the harsh government of the Sui Dynasty", which won the hearts of the people; Second, recruit talents on a large scale to maximize the number of talents for my use; Third, to reward military merits, continue to use and reform the military system, and expand the number of soldiers to meet the needs of the wartime regime; Fourth, appoint the nobles of the former Sui Dynasty, knight them on a large scale, encircle the powerful and powerful, and avoid unnecessary wars.

After a period of operation, Li Yuan established a firm foothold in Chang'an City.
