Among the many rebels who have the ability to enter the main pass, Li Mi has Luoyang to block them, Xue Ju and Liang Shi have just captured many chassis and still need time to digest them, so they can't get out for the time being, and Dou Jiande and others are too far away to enter the main pass.

So at this time, the only one in the world who can enter Guanzhong is the Li family in Hedong, which may be the so-called destiny of heaven!

On the first day of the fifth month of the thirteenth year of the Great Cause (617 AD), Li Yuan appointed Li Yuanji as the Taiyuan Taishou, stayed in Jinyang Palace, and entrusted Li Yuanji with all rear affairs.

On the second day of the first month of May, Li Yuanzhue swore an oath in front of the barracks, and issued a letter to the counties, announcing that Yang Yu, the acting king of Chang'an, was honored as the emperor, and Yang Guang was honored as the emperor, and then commanded 50,000 soldiers to set off from Jinyang and officially march into Guanzhong.

Li Yuan's march into Guanzhong was two months earlier than the original history, and in the original history, Li Yuan only had 30,000 soldiers in unarmored armor when he marched into Guanzhong.

At this time, Li Yuan had 50,000 soldiers, and the 15,000 soldiers in the left leading army were either veterans who had been fighting with Li Yin for many years, or elite soldiers recruited from the miners, with extremely strong combat effectiveness.

The final goal of Li Yuanjun's entry into the customs was naturally Chang'an, Xijing, and the main route of the march was to follow the Fenshui, take the Fenshui River Valley, and go to the southwest, during which the important places that needed to be passed through were Xihe County, Bird Mouse Valley, Jiahubao (now south of Lingshi County, suspected to be between present-day Hanhouling and Nanguan), Huoyi (now Huo County), Jiangjun (now Xinjiang County), Longmen, Pujindu, Fenglingdu in the Yellow River crossing, and Hedong County.

The above important places are only the part before entering the customs, after entering the customs, to think of Chang'an, there are other important places, it can be seen that it is not easy for the Li family to enter the main customs.

Soon after Li Yuangang led his army from Jinyang, the Western Turks sent a man named Ashina Daqi to lead his troops to follow Li Yuan.

On the sixth day of the first month, Li Yin proposed to Li Yuan to send Sima to lead the army in the left army's mansion and lead 3,500 troops to Lishi County to attack the Jihu tribe in his place, so as to stabilize the flank of the army when it marched.

Li Yuan originally planned to send the general counsellor Zhang Lun to lead the army to pacify Lishi County, so after listening to Li Yin's suggestion at this time, he also agreed, but asked a little uneasily: "Lishi is strong, this Li Jing only brings 3,500 people, will it be too little?" ”

Li Yin said that he believed that Li Jing had this ability, and that he could pacify Lishi County with only 3,500 people, so Li Yuan didn't say anything.

On the eighth day of the first month, Li Yuan arrived at Xihe City, when the three brothers of the Li family had just captured the city, but the order in the city was normal, and there was no sign of chaos.

Li Yuan comforted the officials and people of Laoxi River and gave relief to the poor. All those who are over the age of 70 are given the post of loose official, and the rest of the heroes and heroes are awarded the post according to their ability.

Li Yuan inquired about the merits and talents of the person who came, and at the same time registered the official rank conferred. More than 1,000 officials were appointed in a single day. None of the people who accepted the official positions took the appointment certificates, and they each left with the official names written by Li Yuan.

The reason why Li Yuan wantonly sealed the official was to show the officials of other counties, so that others knew that as long as he surrendered to him, he would definitely give him a reward, hoping to alleviate the obstacles on the way to enter the customs, Li Yin still admired Li Yuan's political strategy, and secretly sighed in his heart that Li Yuan was worthy of being an old fritter who had been in the officialdom for many years.

After comforting the officials and people of Xihe County, Li Yuan continued to lead the army to set off and entered the Bird Mouse Valley.

At this time, Yang Yu, the acting king, had sent Huyalang general Song Laosheng to lead 20,000 elite soldiers to garrison in Huoyi, and sent Qu Tutong, the general of Zuo Wuhou, to garrison Hedong to echo Song Laosheng to resist Li Yuan.

On 14 May, Li Yuan garrisoned Jiahu Fort, which was more than 50 miles away from Huoyi.

Jiahu Fort is a necessary place from Lingshi County in Xihe County to Huoyi County, and it is also a barrier in Huoyi County, but Song Laosheng did not send any soldiers to garrison it, so that Li Yuan's army easily occupied it, so Li Yuan and others concluded that Song Laosheng was a brave and unscrupulous person, so they suddenly had a little more confidence to defeat Song Laosheng.

However, at this time, the heavens were not beautiful, and it rained continuously heavily, Li Yuan could not march, and sent Shen Shu'an and others to lead the old and weak soldiers back to Taiyuan, and transported a month's grain, but on the 17th, there was good news that Li Jing conquered Lishi County and captured Yang Zichong, the Taishou.

Although it has nothing to do with the overall situation of entering Guanzhong from Shijun, it can always lift the morale that is a little low due to the continuous rainy weather, and at the same time, because of this battle, everyone remembers the person named Li Jing under Li Yin.

Li Yin looked at the torrential rain outside in the tent at this time, and felt very depressed in his heart.

In the original history, when Li Yuan raised troops into the customs and arrived near Huoyi County, he also encountered continuous heavy rain, so that he could not enter the army, which made him very embarrassed, and the reason why Li Yin strongly advocated starting an incident as soon as possible was to avoid the heavy rain, how did he know that the same heavy rain was also falling at this time, and he really couldn't be depressed.

At this time, Song Zhengben was also sitting in Li Yin's tent, and he suddenly spoke: "Does Lingwu Gong intend to compete with your sons for the throne in the future after your father Tang Gong wins the world?" ”

Lingwu Gong is Li Yin's current title, and now Li Yin's subordinates all call him by title, Li Yuan divides the titles of the five sons, Lingwu, Longxi, Dunhuang, etc. are all places west of Tongguan, Li Yuan This is to show his determination to enter the customs.

Being able to get the title of Duke Lingwu, and the official position of the Governor of the Left Army, and the command of the Left Third Army, Li Yin is still very satisfied.

Li Yin can get such a reward from Li Yuan, which is naturally inseparable from his strength, if it weren't for his hard work in life and death over the years, what he can get at this time will definitely not be comparable to Li Zhiyun

After listening to Song Zhengben's words at this time, Li Yin was silent for a long time, and finally looked at Song Zhengben and said, "If I say yes, what can Mr. teach me?" ”

Song Zhengben's eyes lit up after hearing this, and Li Yin's answer was basically acquiescing to his question.

Song Zhengben pondered for a while and replied: "If the Lingwu Duke intends to compete with the princes, it is best to start preparing now, collect the military exploits to build prestige, and the close ministers around the general and the generals who are guarding the outside will take it as a help, gather talents, accumulate strength, and after a few years, you will have the opportunity to achieve great things with your strength!" ”
