When Li Tang struggled to occupy the southern region, a man appeared in the north who made Tang Dynasty's brain ache and even a little frightened, because this man only spent half a year to fully recover and occupy Dou Jiande's original territory.

This man named Liu Heimin began to raise troops in July of the fourth year of Wude (621), and at the end of December, the Dou Jiande territory in the hands of the Tang family was not yet hot, and it was taken away by the peasant brother Liu Heimin, and the duck in his hand flew like this, how could he not let Li Tang's people grit their teeth, this completely different god of war, made them consume a lot of energy and manpower to clean him up.

This Liu Heimin can be regarded as a veritable legendary man in his life, he is really a good hand at fighting, slaughtering many fierce generals in the Tang Dynasty, and his military talent is not inferior to Li Shimin. If the times are good, it is not impossible to rule the world.

There is no record of when Liu Heimin was born, and there are no ancestors who have been sesame officials, and there are no people who have made a fortune in business, so it can be seen that several generations have been farmers.

He is a native of Zhangnan County, Beizhou (now northeast of the ancient city of Hebei), he does not like to read since he was a child, his character is cunning and arrogant, he is addicted to alcohol and gambling, he does not manage the industry, his family is very poor, and he often lacks food and clothing. Therefore, no matter how bad the situation is, you must first save your life, maybe that day the time will come, and there will be a big event suitable for your personality, waiting for you to complete, so as to go down in history.

First of all, Liu Heimin followed Li Mi to eat, after Li Mi was down by Wang Shichong, he surrendered to the Tang Dynasty, he stayed with Wang Shichong, he had the same idea as Qin Qiong and Cheng Biting Jin, and felt that Wang Shichong was like a witch and unreliable, so he turned his head and took refuge in his good fellow countryman Dou Jiande. Dou Jiande was subdued by Li Shimin and taken to Chang'an, and after being beheaded by Li Yuan, Liu Heimin no longer relied on anyone, so he returned to his hometown, planning to plant a few acres of thin land, so that the world disputes no longer have anything to do with him.

- It is safest not to fight with others.

So...... Liu Heimin decided to be a quiet little farmer.

This is after Dou Jiande, a good fellow countryman followed by Liu Heimin, was beheaded in Chang'an, he gave up the pessimistic idea of struggle and made an action: he did farm work in the field with his face to the loess and his back to the sky.

He was at peace with the crops, and when he sought that peace, the chaos of the outside world seemed like a powerful whirlpool, which finally sucked him back into the cruelty of war.

The main force of the Xia army collapsed, and Dou Jiande was beheaded, but the rest of his people were still scattered among the people and continued to oppose the Tang family.

In order to eliminate this part of the force, the Tang family arrested some of Dou Jiande's generals on the grounds of "atrocities in the township".

The treasury property of Zhaozhou was robbed and emptied by the remaining people, and the Tang family tortured and charged him with the reason of recovering the treasury, which made Dou Jiande's subordinates panic and couldn't sleep soundly.

However, the Tang dynasty adopted a policy of appeasement for Dou Jiande's important old generals, such as Fan Yuan, Cao Zhan, Dong Kangmai and Gao Yaxian.

They were "called" by the Tang family and discussed privately whether to follow the Tang family, and they agreed that the Tang family was unreliable and would fool them to Chang'an, and then slaughter them like their boss Dou Jiande. Therefore, they will never go to Chang'an, and going is a dead end.
