After crossing the Yellow River from Longmen to the west, it is Feng Yi County in Guanzhong, and the southwest of Feng Yi County is Jingzhao County, where Xijing Chang'an is located, so it is particularly important to find out the specific situation of Feng Yi County now.

There are people in the army who have recently surrendered and are familiar with Feng Yijun to tell everyone that Feng Yijun's name is Xiao Zao, who is the most greedy for life and afraid of death, if the army approaches, he will surrender the city, and among the Feng Yijun bandits, a person named Sun Hua is the strongest, with more than 30,000 people.

After hearing this, Li Yin took the initiative to ask Ying: "Father, please let me cross the river to Feng Yijun to personally recruit Sun Hua!" ”

As soon as Li Yin said this, everyone in the army was surprised, and Li Yuan hurriedly shook his head and said: "What is Sun Hua's temperament, we don't know yet, how can Wu'er take risks easily?" ”

Li Yin said resolutely: "Feng Yijun is too guarded by Xiao Zao and don't have to worry too much, if Sun Hua surrenders to us, then Feng Yijun's group of thieves will be able to surrender to us, Feng Yijun will soon be owned by my Li family, and my Li family will be able to gain a foothold in the pass, so Sun Hua is very important, and it is worth the child to take the risk to recruit him!" ”

Li Yuan still didn't agree, Liu Wenjing and others also thought it was too risky, but Li Yin's attitude was very resolute, Li Yuan finally had to agree, but he told Li Yin to be cautious on this trip, Li Yin nodded seriously and agreed.

The next day, Li Yin only took Su Dingfang, Fu Ying and a few other people, and then took a lonely boat, crossed the roaring Yellow River, and arrived at the boundary of Hancheng County, Fengyi County, Guanzhong.

In the northeast of Hancheng County, there is a big mountain named Liangshan (this Liangshan is not the water margin of the water and Liangshan, near the Yellow River), and Sun Hua's people and horses are entrenched in Liangshan.

When Li Yin, Su Dingfang and others just walked in the direction of Liangshan, they suddenly saw dozens of horsemen and horses running in front, and these dozens of horsemen and horses stopped near Li Yin and others, and the first one said respectfully: "The one in front is Lingwu Gong?" The villain Sun Hua asks to see. ”

……

On June 28, the thirteenth year of the Great Cause, Li Yuan led the army from Longmen County to the south, arriving in Fenyin County (now Ronghe County North Jiuli), on the first day of the seventh month, Li Yuan marched to Hukou (now the west foot of Longmen Mountain), the people by the river offered more than 100 people to Li Yuan every day, and Li Yuan established a naval army for the army to cross the river.

At this time, three days had passed since Li Yin crossed the river to persuade Sun Hua to surrender, and Li Yin had no news, and Li Yuan, Liu Wenjing and others were a little worried about this.

Of course, there are also people who are secretly happy in their hearts, such as Pei Lian, who is closest to Li Yuan, he has always been not very good with Li Yin, since Taiyuan raised troops, there have been several times when his opinions were refuted by Li Yin on the spot, and what made Pei Lin even more embarrassed was that basically every time he finally proved that Li Yin's suggestion was right, which made Pei Lin secretly hate Li Yin in his heart.

At this time, if he was allowed to take only a few people across the river, he would persuade the most powerful rebels in Feng Yijun to surrender and let Li Jun gain a foothold in Guanzhong, then Li Yin's credit would really be incomparable.

"Hmph, Li Yin'er is so bold, I think he must have gone and never returned this time!" Pei Lin laughed secretly in his heart, if it wasn't for someone present, he would definitely be able to help but laugh a few times.

At this time, Pei Lin suddenly heard a commotion outside, and as soon as he walked outside to find out, he heard many soldiers shouting loudly: "Lingwu Gong is back, Lingwu Gong is back!" ”

Pei Lian's expression froze after hearing this, and his face became unsightly......

Li Yin bowed to Li Yuan and said, "Father, my son is fortunate to have fulfilled his mission and recruited General Sun Hua to surrender, and General Sun Hua himself is outside your big tent!" ”

"Okay, okay, Wu'er rode into the enemy camp alone and surrendered the enemy army, which is farther than the ancient Banding!" After hearing Li Yuan praise himself like this, Li Yin secretly felt ashamed in his heart.

The reason why he crossed the river so confidently to recruit Sun Hua was not because of how bold he was, but because he knew that in the original history, Sun Hua only crossed the river alone to surrender when he received a letter from Li Yuan.

So Li Yin's trip seems to be extremely dangerous, in fact, he went on an outing, and then picked up a great credit in vain, and the most dangerous place in the middle was just when he crossed the Yellow River in Longmen, the water was too turbulent, and the lonely boat seemed to sink at any time......

Li Yuan took Sun Hua's hand and sat with him, rewarded him, and named him Doctor Zuo Guanglu and Wuxiang County Prince, and appointed Feng Yi as Taishou. Sun Hua's meritorious people let Sun Hua confer official positions in turn, and the rewards were very rich.

Li Yuan asked Sun Hua to cross the river first, and then sent Wang Changhuan of the Left Commanding Army, Liu Hongji, the general under Li Yin's account, and Shi Chen Yanshou, the commander of the Left Army, and Shi Daqi, the doctor of Jin Ziguanglu (who was the Western Turk Ashina Danai who Li Yuan raised his army and later took refuge), led 6,000 infantry cavalry to cross the river from Liangshan, camped in Fengyi County to wait for the arrival of the army, and appointed Ren Huan as a consolation ambassador to persuade Hancheng to surrender, and soon, Hancheng surrendered.

Before Wang Changhuan, Liu Hongji and others crossed the river, Li Yuan said to them: "Qu Tutong has a lot of elite soldiers, and they are only more than 50 miles away from our army, but they dare not come to battle, which is enough to prove that Qu Tutong's subordinates no longer serve him. But Qu Tutong was afraid of being blamed from above, and he didn't dare not fight. If he personally leads his army across the river to attack you, then I will attack Hedong, and Hedong will definitely not be able to hold it. If Qu Tutong defends the city with all his troops, then you will tear down the bridges over the river. In this way, the front chokes him, and the back attacks his back, and if he does not escape, he will surely be captured by us! ”

Li Yuan's plan to attack Qu Tutong on both sides was offered to him by Liu Wenjing, but it was the only good strategy to deal with Qu Tutong at this time, so it was adopted by Li Yuan, and Wang Changhuan, Liu Hongji and others took the order.

Qu Tutong also knew that if Liu Wenjing's plan succeeded, then he would fall into a very passive situation, so after Wang Changhuan, Liu Hongji and others crossed the Yellow River, he sent Huyalang General Sang Xianhe to lead thousands of Xiaoguo to attack the camp of Wang Changhuan and others by night.

Wang Changhuan and others fought unfavorably, and at a critical juncture, Sun Hua and Shi Daqi attacked Sang Xianhe from behind with rangers and defeated Sang Xianhe.

Sang Xianhe escaped and fled back to the city and destroyed the Yellow River bridge. In July, on the eighth day of the first lunar month, Feng Yi was too shou Xiao Zao to surrender to Li Yuan.

On the tenth day of the first month, Li Yuan commanded the armies to surround the county of Hedong County, Qu Tutong closed the city and refused to defend, because Qu Tutong defended the city properly, Li Yuan's army tentatively attacked the city several times, and the casualties were large, so Li Yuan had to order the siege but not attack.

At this time, Pei Lin called on the generals to promote Li Yuan as a lieutenant and add official subordinates, Li Yuan accepted this suggestion and was promoted to a lieutenant.
