Wang Shichong led more than 100,000 people to Luokou, and the generals included Yang Zhu, Yang Gongqing, Guo Shiheng, Guo Shizhu, Dong Jun, Zhang Tongren, Zhu Cang, Wang Renze and others.

Under the leadership of Li Mi and Zhai Rang, the Wagang army was no less than 100,000 people, and the generals included Shan Xiongxin, Xu Shixian, Qin Qiong, Cheng Yanjin, Pei Renji, and Luo Shixin.

Since the last time Li Mi offered a plan to defeat Liu Changgong, Zhai Rang gave up the first position in Wagang to Li Mi and respected Li Mi as the Duke of Wei.

Also in 617, Li Mi led the Wagang army to set up an altar in the southern suburbs of Gongxian County, sacrificing to the heavens and ascending the throne, the country was called the Western Wei Dynasty, and the year was known as the first year of Yongping. Shan Xiongxin was appointed as the general of the left Wuhou, Xu Shiyun was appointed as the general of the right Wuhou, and even the newly joined Qin Qiong and Cheng Yanjin were also named generals.

Soon after the founding of the Western Wei Dynasty, Meng Rang, the leader of the rebel army in Changbai Mountain, Shandong, led his men and horses to join Li Mi, Shi Chai Xiaohe, the magistrate of Gong County, Henan, and Shi Zhengyi, the imperial servant, surrendered the county seat to Li Mi, and the Sui Dynasty Hu Benlang took Pei Renji and his son Pei Xingyan to surrender to Li Mi, and the power of Wagang rose sharply for a while.

In order to suppress the old man of Wagang during the Zhai Rang period, Li Mi boldly appointed the newly attached generals, awarded Pei Renji the official title of Shangzhu State, and was named the Duke of Hedong County, which undoubtedly caused the dissatisfaction of the old ministers of Wagang, and Zhai Rang was also angry in his heart.

After a period of time, Shi Chai Xiaohe, the former magistrate of Gong County, persuaded Li Mi to say: "King Qiwei, my subordinates have a strategy here to help the king set the world, I don't know if the king can be interested." ”

Li Mi was surprised: "Come quickly." ”

Chai Xiaohe said: "Guanzhong uses the mountains as a barrier and the Yellow River as a moat, Xiang Yu will perish if he leaves here, and Liu Bang will succeed in building the capital here." My idea is to let Pei Renji guard back to Luocang, Zhai let the town guard Luokoucang, you personally select an elite team to raid Chang'an to the west, Guanzhong is now a major general, and it will definitely be decided in a battle. ”

Chai Xiaohe saw that Li Mi, who was on the throne, did not say anything, and continued: "Once Chang'an is conquered, go back and take Kunshan and Hangu Pass, and then capture Luoyang, so that the world can be passed on to the world, I don't know if the king can be interested." ”

After thinking for a long time, Li Mi said: "I have also thought about your strategy, it is really a good strategy." But Yang Guang's faint monarch is still there, there are still many troops in his hands, and our team, most of them are from Shandong, and there are many old Wagang troops, and they are not all subservient to me, and before Luoyang is conquered, I am afraid that no one will want to follow me to capture Chang'an. ”

After a pause, Li Mi continued: "Many of the generals of the Wagang Army are from the green forest, if they are left behind, I will bring my own troops to capture Chang'an, and I am worried that they will each claim king, if so, it will be all over!" ”

As soon as Chai Xiaohe heard it, he understood that Li Mi was not a man of great talent, and now he could only take one step at a time.

In this gap, Li Yuan picked up a bargain, easily took Chang'an, and captured the land of Guanzhong, so that it had the strength to compete in the Central Plains.

When the news of Li Yuan's capture of Chang'an came, Li Miton, who was still fighting in Luoyang, beat his chest and shouted pity, so he was even more anxious to capture Luoyang.

Wang Shichong led the army to Luoyang, before Li Mi fought a big battle, Li Mi due to fewer soldiers and horses, Wang Shichong won a big victory, Li Mi's remnants fell into the water when Chai Xiaohe drowned, Li Mi was seriously injured, vowed to avenge the death of his brother, so he mobilized 100,000 troops to confront Wang Shichong and Luokou.

The two sides fought in Luokou for more than 100 days, but because the granaries near Luoyang were occupied by the Wagang army, it was protracted, and Wang Shichong's supply of grain and grass became a problem.

Seeing that the cold winter is coming, although Li Mi's side has plenty of food, it is difficult to replenish the cold clothes for a while. Wang Shichong made conspiracies and tricks, and sent people to Li Mi's camp secretly to meet Li Mi.

Wang Shichong's envoy said to Li Mi: "My general heard that the king of Wei is short of winter clothes here, and there are too many cotton clothes in the Luoyang treasury to run out. ”

Li Mi said secretly: "Although Wang Shichong also has more than 100,000 troops, but they are all temporarily transferred, there is no need to be afraid, seeing that this battle is difficult to distinguish the victory or defeat for a while, if there is no cotton clothes to keep out the cold, our army will be in chaos, why not exchange with him first, and wait for the capture of Luoyang grain or mine." ”

So Li Mi agreed to Wang Shichong's request, because the lack of cotton clothes was indeed a serious problem faced by the Wagang army, so no one in the Wagang generals objected. Li Mi's abacus sounded, but he didn't know that this move helped Wang Shichong a lot, as soon as the food arrived, Wang Shichong's army was settled, and there was no more desertion, the army was unprecedentedly united, and Wagang's plan to easily take Luoyang was estimated to be in vain.

Just when the two sides were facing each other, Yang Guang, who was in Jiangdu, made another stupid move and helped Li Mi a lot.

Yang Guang saw that Wang Shichong and the Wagang army could not hold on, so he ordered someone to go to the army to make Wang Shichong a general, urging him to break through the Wagang army as soon as possible, so that he could return to Jiangdu. Wang Shichong received Yang Guang's order, and his heart was bitter.

But the angel was on the side, and Wang Shichong's strength was not enough to resist the imperial court, so he had to order the army to strengthen Luoshui, and then attacked Li Mi by a surprise attack, but was defeated by Li Mi, who had been prepared.

When the generals Yang Zhu, Yang Gongqing, Dong Jun and others rushed to cross the pontoon bridge with their soldiers, they fell into Luoshui and drowned, and the army led by them was drowned more than 10,000 people. Because of the sudden heavy snowfall that night, the weather was very cold, and on the way back to Luoyang, tens of thousands of people were frozen to death, only more than 1,000 people returned to Luoyang, Wang Shichong tied his hands to the emperor to ask for guilt, and was released by Yang Tong, the king of Yue, Wang Shichong gradually gathered nearly 20,000 escaped soldiers in Luoyang.

Yang Tong gave the responsibility of guarding Luoyang to Wang Shichong, Wang Shichong took over the military and political power of Luoyang City, because the grain exchanged with Li Mi was enough, the city was held, and the military spirit was relatively stable, so Li Mi led the army to attack Luoyang for a long time, the weather was too cold, and finally had to withdraw to the other side of the Luohe River, and the two sides confronted each other again.
