A few days after Fang Hong returned to the camp, the generals of Zong Luohu's army, Liang Hulang, Neishi Ling Zhai Changsun and others, actually led their respective teams of more than 8,000 people to Li Yin's camp to surrender, and brought a message to Li Yin: Zong Luohu's army has eaten all the food!

This Liang Hulang is the person who Song Zhengben bought when he carried out a divisive plan against Xue Ju and Xue Rengao's father and son, but at that time, Liang Hulang just saw Song Zhengben's heavy money and promised to convey the false news that Song Zhengben wanted him to say to Xue Rengao, and did not really take refuge in Li Yin.

Li Yin warmly received Liang Hulang and others when they brought troops to surrender at this time, but Li Yin did not dare to believe the truth of the news they brought when they surrendered, and immediately sent Fu Ying and others to inquire about the information.

After all, it can be seen from Xue Rengao's recent battles that although his people are brutal and unkind, in the use of troops, they are not only reckless, but also quite strategic, if he lets Liang Hulang fake surrender and bring false news to lure Li Yin into battle, it is not impossible.

After some careful investigation by Fu Ying and others, Li Yin finally knew that it was thousands of soldiers and horses from the four counties of Lintao, and after entering Longyou, they plundered the grain and grass that were ready to be sent to the front line, and after about two months of confrontation, the grain and grass in Western Qin were somewhat insufficient, so this led to the dilemma of lack of food for Zong Luohu's army now.

After Xue Rengao succeeded to the throne, his generals and soldiers already had the heart of divorce, and at this time, when they encountered a shortage of food, they did not want to continue to mix with Xue Rengao, so they led the troops to take refuge with Liang Hulang and others a few days ago.

After finding out everything, Li Yin knew that the time had come for the army to set out!

On October 17, Li Yin ordered Liang Shi, the head of the march, to camp in the shallow water plain to lure Zong Luohu to attack.

Zong Luohu was very happy when he learned the news, he didn't care if it was a bait or not, because his army really couldn't drag on any longer, he immediately dispatched all the elites to attack Liang Shi's camp.

Liang Shi held the danger to hold on, he was not thoughtful when he set up camp, there was no water source in the camp, and he guarded for several days, and the men and horses had no water to drink.

Zong Luohu's attack was very fierce, and Li Yin estimated that the other party was tired, so he raised his tent and said to the generals: "Didn't you always ask for war before? Now it's time to play! ”

When the day was approaching dawn, Li Yin asked Pang Yu, the general of the Right Martial Candidate, to line up in the shallow water plain.

Zong Luohu combined his troops to attack Pang Yu, Pang Yu fought, and could hardly hold on, Li Yin led the army to appear from the north of the shallow water plain by surprise, and Zong Luohu led the army to meet the battle.

Li Yin led dozens of horsemen to rush into the enemy formation, the Tang army fought hard inside and outside, the cry was moving, Zong Luohu's troops were defeated, and the Tang army killed tens of thousands of people.

Li Yin wanted to personally lead more than 3,000 cavalry to pursue Zong Luohu, but Li Yuan's cousin and Yong'an King Li Xiaoji grabbed Li Yin's yellow horse and persuaded bitterly: "Xue Rengao still occupies a strong city, although we defeated Zong Luohu, but we can't easily rush in, please King Jin hold his troops for the time being, observe Xue Rengao's movements and make plans." ”

Li Yin dismissed Li Xiaoji's suggestion, "Now that our army is winning like a bamboo, the opportunity cannot be lost, uncle, don't say it again!" ”

Li Yin then continued to march, killing the Western Qin army, and finally approached Gaocheng City, Xue Rengao had just come to Gaocheng from Longzhou recently, after he gathered the defeated army, he personally fought in Gaocheng City, preparing to face Li Yin's army head-on, in order to save the decline, Li Yin faced Xue Rengao's camp according to the Jing River.

However, just when the two sides were preparing to fight, Xue Rengao's generals Hun Gan and others successively led their troops to the Tang army to ask for surrender.

After seeing Li Yin's attitude towards Hun Gan and the others, more generals in Xue Rengao's army wanted to surrender.

After Xue Rengao saw this situation, he was a little scared, and he didn't dare to fight with the city again, so he led his troops into Gaoqi City to refuse. When it was almost dark, Li Yin's follow-up armies arrived one after another, and more than 100,000 people surrounded the city of Gao Kai City.

In the middle of the night, the defenders of the city went down to the city one after another to surrender, and only a few days later, most of Xue Rengao's soldiers in the city surrendered.

Xue Rengao was poor and poor, knowing that the general trend had gone, and the resolute surrender faction of the Western Qin State, Huangmen Shilang Yuliang, once again persuaded Xue Ju to surrender a few months ago, that time, Xue Ju finally refused to surrender under the persuasion of Hao Ming, and this time, no one around Xue Rengao spoke out against it, and Xue Rengao himself finally nodded to Xue Liang.

On the second day of November in the first year of Tang Wude, Xue Rengao led hundreds of officials, opened the city gate, put out the city, knelt down and surrendered to Li Yin, and occupied the Western Qin of Longyou.

Subsequently, Li Yin continued to march eastward, entering the eastern area of Longyou from the Longshan Pass, and it didn't take much time to get the land, elite soldiers and people of Western Qin.

And on the way back to Chang'an, Li Yin suddenly had a subordinate from Luoyang, the eastern capital, who told him about the earth-shattering changes from the Central Plains......

Li Mi was weak because the army of the Eastern Capital had lost several battles, and seeing that the Eastern Generals were killing each other, he thought that he could level the Eastern Capital in the short term, and because the faith was better than Yu Wenhua, he was arrogant in his heart.

And because although there was a lot of grain in the warehouse in the occupied place, there was no money and cloth, so the soldiers made meritorious contributions, and there was nothing to use for rewards, and Li Mi gave extremely preferential treatment to the newly attached Jiangdu Xiaoguo, and opposed the original veterans' lack of kindness, so that the majority of soldiers gradually became dissatisfied in their hearts.

In addition, the internal soldiers are still suspicious due to Li Mi's killing of Zhai Rang, so at this time, although Li Mi's army has the prestige of being invincible, the crisis lurking in the army is actually very big, and if there are no remedial measures, the consequences are only a little unimaginable.

On the other hand, Wang Shichong, who was newly powerful in the Eastern Capital, eliminated all dissidents, rewarded soldiers, repaired equipment, secretly accumulated strength, and was ready to seek Li Mi at any time.

At that time, the army of the Sui Dynasty was short of food, and Li Mi's troops were short of clothes, Wang Shichong asked for an exchange with each other, Li Mi felt embarrassed, Changshi Bing Yuanzhen and others sought their own personal interests, persuaded Li Mi to agree to the exchange, and Li Mi agreed.

It turned out that hundreds of people in the eastern capital surrendered to Li Mi every day, and after getting food, fewer and fewer people surrendered, and Li Mi regretted it at this time and stopped exchanging.

Although Li Mi defeated Yu Wenhua before, he also lost a lot of elite soldiers and horses, and the soldiers were also very tired, and there were many sick people.
