In late spring and early summer, the river began to drown out the moraine pebbles at the mouth of the West Ridge Estuary.

The part of the stacked stone formation of the "Water Eight Array" that is exposed to the water surface is getting smaller and fewer, and finally only the top is left, like a chessboard star.

In April of the third year of Wude, Li Yaoshi moved the daily water warfare teaching from the "Water Eight Formations" at the West Rima Water Mouth to the "Dry Eight Formations" at the Shima River Estuary; The selected special forces training will stay in the "Eight Water Formations" where the river water is rising day by day.

Their goal is to carry out their mission a year later, when the river is rising and turbulent, and the enemy is afraid of the weather, and the water is still in the air.

When Li Xiaogong and Li Yaoshi practiced the "Ten Strategies of Tuxiao Milling" one by one in Shannan and made steady progress, Li Shimin had won a great victory in Hefen and returned to Chang'an.

Before long, the party entered Curzon Prefecture.

Li Yuan ordered Li Shimin to build a platform in Yizhou to prepare for the party.

Yizhou is just west of Shinshu, Li Shimin took the time to visit, and the three of them rejoiced again.

Li Xiaogong and Li Yaoshi praised the battle of Qin Wang Baibi as "quiet as a virgin, moving like a rabbit", which won the essence of the art of war in "Sun Tzu".

Li Shimin praised Shinshu's plan to organize special forces and build special ships, and decided to follow suit.

He personally selected more than 1,000 elites for strict training, and specially designed clothes and armor for them.

Every time he goes out, Li Shimin must also wear Xuan armor, personally lead this strong army to charge, invincible, invincible, and famous for a while, so that the enemy army is terrified.

That's a later story, and that's at the time.

Although Li Shimin defeated Liu Wuzhou and Song Jingang in Hefen, forcing them into the Turks; Wang Shichong of Luoyang, but took advantage of the fact that the main force of the Tang army was transferred to the north.

He contacted the Turks to contain Li Tang, and got Luo Khan to give him a good horse and capture several states of Li Tang.

Li Yuan had no choice but to edict Li Shimin to return to the north and ask Wang Shichong.

During this period of time, whether Pharmacist Li was discussing with Li Xiaogong in the governor's mansion, discussing with Zhang Bao on the teaching field, or returning home to face the dust, everyone would always be concerned about Li Shimin's progress in the northern battlefield.

Only Lu Zesheng, he only did his best to the tasks assigned by Pharmacist Li, and ignored everything else.

In the second half of this year, in the Central Plains, Li Shimin and Wang Shichong confronted each other only across the Luoshui.

The six granaries of the Sui Dynasty were all under the control of Li Tang, Luoyang was short of grain, and Li Shimin's army was advancing.

Among them, Zhang Gongjin later became an important backbone of the Qin Mansion, and was also the right-hand man of Pharmacist Li, and was one of the twenty-four heroes of the Lingyan Pavilion.

In Biansai, the Turks cooperated with Wang Shichong to disturb and annex the state, and Liu Shirang, the governor of the state, retreated.

The northeast of Luoyang is Dou Jiande's domain, Li Tang and Wang Zheng do not want Dou Xia to support each other, while Dou Jiande is happy to see the two sides contending.

At this time, Wang Shichong's situation became increasingly cramped, so he had to ask Dou Jiande for help.

Dou Jiande knew that once Wang Zheng was destroyed, Dou Xia would not be able to protect himself, so he agreed.

Li Yuan transferred Liu Shirang to the Eastern Battlefield and attacked Dou Xia's capital of Yuzhou from the north.

The time sequence entered the martial arts for four years.

Wang Shichong's crown prince Wang Xuanying transported grain from Wugaoguan into Luoyang, but was intercepted by the Tang army, and the soldiers' grain and straw were captured by the Tang army.

Li Shimin sent Li Shiji to attack Wujiao Pass at night and captured a number of officials of Wang Zheng's clan, among whom Changshi Dai Bin later became a famous minister of Zhenguan.

Seeing that the time was ripe, Li Shimin asked his father for orders and sent troops to attack the eastern capital.

Li Yuan said: "The conquest of Luoyang is to stop the army." After conquering, its multiplication and legal objects, picture equipment, and things that could not be used by private people were all sorted out and received by the King of Qin. The rest of the children were given to the soldiers. ”

This is tantamount to reaffirming that between his father and son, Li Shimin "lived in Luoyang, since Shaanxi has been in the east, and it is suitable for the Lord."

still makes Ru build the banner of the Son of Heaven, such as the tacit understanding of the story of King Liang Xiao.

Li Shimin knew that there was a shortage of food in the eastern capital, so he went deep and besieged Wang Shichong.

Luoyang ran out of food, and Wang Shichong asked the Turks for help.

At this time, Luo Khan had died, and Jieli Khan succeeded to the throne and led the army into Koufenyin.

Li Yuan had only transferred Liu Shirang from Bingzhou three months earlier, and now he had to be transferred back to defend against the Turks.

After Liu Shirang left, Dou Jiande was no longer restrained in the north, and immediately sent troops to the west, pointing directly at Wugao Pass; At the same time, land and water were used to transport grain into Luoyang.

Li Shimin asked Qu Tutong to assist Li Yuanji in besieging the eastern capital, and he led the elite of Xuanjia to Wujiao Pass.

Dou Jiande underestimated the enemy and was defeated and captured by Li Shimin.

Li Shimin locked Dou Jiande in a prison car and took him to Luoyang City to demonstrate to Wang Shichong.

Wang Shichong originally wanted to break through, but no one followed, so he had to surrender.

This is the famous "First World War and Two Kings" in history.

The Tang army took Luoyang, the military discipline was strict, and there was no crime in the autumn.

Li Shimin entered the palace and seized the Sui Dynasty book edict, but found that it had been destroyed by Wang Shichong.

I had to order someone to seal the treasury and collect gold and silk to give to the soldiers.

He also beheaded the people who committed major crimes in Wang Zheng's party, such as Duan Da, Zhu Cang, Shan Xiongxin, etc., on Luoshui.

Du Ruhui's uncle Du Yan was also in the Wang Zheng Dynasty, he and Du Ruhui's brother have always been not on good terms, once falsely accused Du Ruhui's brother of death, and imprisoned Du Ruhui's brother Du Chuke, almost starved him to death.

Wang Zheng was defeated, Du Yan was punished, but Du Chuke wept and begged Du Ruhui to save him.

Du Ruhui refused.

Du Chuke said: "Uncle Yu has killed his brother, and now his brother has killed his uncle again, and within one door, they are killing each other, isn't it painful!" ”

I want to kill myself.

Du Ruhui had no choice but to ask Li Shimin for Du Yanfang to be spared death.

After the defeat of Dou Jiande, except for Liu Heimin and Xu Yuanlang, who still possessed a small part of Shandong, Heluo was determined, and the northern half of the land of China was included in the territory of Li and Tang.

Three and a half years ago, Li Zong talked about the world, and Li Shimin had almost completed half of his work with the lofty ambition of "you and I are one in the south and one in the north, and the great rivers and rivers are leveled."

The other half has to rely on Pharmacist Li.

In July of the fourth year of Wude, Taiwei, Shang Shuling, and Li Shimin, the king of Qin, led the army to triumph under the magnificent honor guards advocated before and after.

Li Tang dedicated Wang Shichong and Dou Jiande's two captives, as well as the royal treasures such as the Sui Dynasty Chengyu, to the Taimiao Temple in a solemn ceremony.

Li Yuan's original intention was to behead Wang Shichong and Dou Jiande, but Wang Shichong said that Li Shimin had promised him immortality.

Li Yuan had no choice but to pardon him for capital punishment and exile to Shu, where he was later killed by his enemies on the way.

As for Dou Jiande, he was beheaded in Chang'an.

Dou Jiande is a heroic man of benevolence, righteousness and generosity, while Wang Shichong is a traitor who is jealous of narrow guesses.

At this time, Dou Jiande and Liu Wang Shichong were beheaded, and quite a number of historians believed that after the unjust killing of Liu Wenjing, this matter could be described as the second "loss of sentence" in the early Tang Dynasty.

However, for Li Shimin, Wang Shichong said that he had promised him not to die, and Li Yuan pardoned him for capital punishment.

This is tantamount to his father once again confirming the original tacit understanding, allowing him to "build the banner of the Son of Heaven, such as the story of King Liang Xiao".

However, at this time, Li Shimin was no longer satisfied with "living in Luoyang, since Shaanxi has been in the east, and he is the lord of Xiyi".
