At this time, Wang Shichong in Luoyang had been surrounded by Li Mi's army, and Li Mi planned to capture the eastern capital Luoyang as his base camp, so he besieged Luoyang for several months at all costs.

In order to solve the predicament of Luoyang, Yuan Wendu said to Wang Shichong: "Yu Wenhua and this traitor, there is no father, and now the siege of the Wagang army is very urgent, it is better for us to pour all the treasury treasures to temporarily lure Li Mi, and in the name of the emperor Xu Zhi high-ranking officials Houlu, and then tell Li Mi that Yu Wenhua has led an army of 100,000 to secretly go north, ready to find the bad luck of the Wagang army, let Li Mi go to Yu Wenhua and the dog thief to tear up, and when the vitality of both of them is greatly damaged, we can sit and reap the profits, how about it?" ”

Wang Shichong thought so, so he played the son of tomorrow, named Li Mi as Taiwei, Shang Shuling, and Wei Guogong, and told Li Mi that as long as he could pacify the Yu culture and the rebellion, he would let him come to Luoyang, and at the same time give all the treasures of the Luoyang Treasury.

Li Mi was already greedy for small gains, and saw that Gao Buer had the reputation of a king of Chu to fight for invincibility, and he did his own thing with a false title, and he could not delay and maximize his own interests, so he happily accepted Yang Tong's reward.

After Li Mi accepted the reward from the imperial court, he declared himself a vassal to the imperial court, and the emperor ordered him to send troops to attack Yu Wenhuahe, so Li Mi removed the soldiers and horses besieging Luoyang, and turned to fight against Yu Wenhua and at Liyang.

This move caused dissatisfaction among many generals in Wagang, Cheng Biting Jin said: "This Li Mi stoops down to be someone else's eagle dog, my generation despises, the big husband is rampant in the world, when he creates his own meritorious deeds, since Zhai Da is in charge of Li Mi's victimization, Wagang seems to be stronger than a day, but in fact it is just a group of straw bales, my brother should find a way out." ”

Xu Shiyun said: "Bite Jin Shenyan, it's just a matter of saying this in front of our own brothers, don't let others listen to it, and follow in the footsteps of Zhai Da's family." ”

Shan Xiongxin said: "Now this Li Mi is becoming more and more intolerant, he has always acted autocraticly, greedy for pleasure, and disregarding the life and death of his brothers, such bastards, why should we respect him as the master." ”

Qin Qiong also said: "Second Brother Xu has always been resourceful, what do you say our brothers should do." ”

Xu Shiyun glanced at the brothers with his eyes, and whispered: "Since you and my brothers have plans to vote for another master, why don't we start arranging it, especially if the family wants to settle down and find time, how about we turn against each other?" ”

Everyone praised it, and they did it.

Li Mi led more than 300,000 soldiers and horses, far exceeding the 100,000 horses of Yu Wenhua, and Yu Wenhua was a labor expedition, and there was not enough food and grass, so Li Mi was ready to fight a protracted war with him.

Li Mi sent Xu Shiyun to guard Cangcheng, but Yu Wenhua and many attacks were unsuccessful. In the end, the two armies confronted each other on both sides of the Wei River.

Li Mi said to Yu Wenhua on the other side of the river: "Your father and son were originally the efforts of the Huns, met the first emperor, and with the merit of support, they were favored by the emperor, and they were rich and noble for generations, and you also married the princess as a wife, and your family was deeply favored by the emperor, and there is no one else." Your Majesty waits for you to be a national soldier, how do you repay it? killed the king with his own hands, and also killed his children and grandchildren, such a traitor, heaven does not tolerate it. ”

Yu Wenhua and said angrily: "You are not much stronger than me, first the army was defeated and fled, and the grass was a coward, and he was also a fatherless and motherless person, and he was also a wall grass, what kind of face do you have to teach me a lesson, we will see the real chapter under our hands." After that, Le Ma returned to the camp, urged the siege tools to be made, and at the same time constantly sent troops to attack Cangcheng, trying to cut off the grain and grass of the Wagang army to make it chaotic.

How could Li Mi let him succeed, in a dark and windy night, he sent troops to attack Yu Wenhua and burned all his siege equipment, so that Yu Wenhua fell into a dilemma.

The two sides were deadlocked for more than half a month, and Li Mi found out that there were already difficulties in the supply of Yu culture and grain and grass, so he sent an envoy to falsely claim: "I came to attack you because the emperor in Luoyang was instigated by Wang Shichong and gave an order. Now that we are exhausted, we can only cheapen Wang Shichong for nothing, why don't I send you food, let's shake hands and make peace and attack Wang Shichong together. ”

Yu Wenhua is also a stubborn son who is not minced meat, and there is no strategy in his chest, as soon as he heard that there can be a truce and food, he agreed to Li Mi's suggestion and ordered the camp to no longer limit rations, and the army celebrated for three days.

Who knew that after three days, the food promised by Li Mi did not come, Yu Wenhua and sent someone to Li Mi to ask for the guilt, and was killed by Li Mi after taking it.

Due to the lack of soldiers and generals, the two sides fought for a day, Yu Wenhua and the defeat was withdrawn to Wei County, and the remaining soldiers and horses were less than 20,000. At this point, Yu Wenhua also knew that his general trend had gone, and said to the people around him: "People will die in this life, how can they not dream of the emperor!" ”

So, Yu Wenhua killed Yang Hao and established himself as the emperor, the country name Xu, and was later captured by Dou Jiande and killed by Dou Jiande.

"Book of Sui" commented on Yu Wenhua and said: "Hua and Yong Peng's talents, negative grace and tired leaves, Wang Chong Dou Xiao Xiao, fortunately at the right time, he was rewarded, and he was more than the old minister." Since it is a period of collapse and stripping, it cannot cause exhaustion, but because of the convenience of profit, the first attempt to dry the discipline, the group does not succeed, the position is chaotic, the source of the plug is pulled, and the crown is cracked and the crown is destroyed. or bow to the head, or personally carry out poison, provoke the deer, and eat the deer, which is not tolerated by heaven and earth, and is indignant by people and gods. Therefore, the fierce leader of the owl and the deer, looking for each other, the snake and the ugly, following the heel and the heel, the fast loyalty and righteousness in the year, and the ring in the leaves. Woohoo, those who are ministers are not good at it! It's not a good thing! ”

The failure of Yu Wenhua and the Northern Expedition enabled Li Zitong to successfully capture Jiangdu and its nearby counties, obtain a large amount of goods, and strengthen his own power.
