In the summer of the thirteenth year of the great cause, Li Yuan and Taiyuan raised troops, led more than 100,000 troops to the western capital Chang'an, although Guanzhong was dangerous, but because of natural factors such as the thick soil of Taiyuan, Shanxi, only a few barriers such as Huoyi could isolate the two places, at this time the emperor Yang Guangyuan was far away in Jiangdu, and Chang'an was guarded by the young acting king Yang Yu, Qu Tutong and other generals assisted, Guanzhong troops were empty, once Li Yuan's army broke through the Huoyi line, the form would be unimaginable, and the acting king Yang Yu immediately adjusted his teeth to Song Laosheng and 20,000 elite soldiers, Stationed in Huoyi to defend against Li Yuan's army from Taiyuan, Qu Tutong led another elite army into Tongguan, forming a threat to Li Yuan's army from the flank, and acting king Yang Yu sat in Chang'an, and actively strengthened the Chang'an guard, so as to prevent Li Yuan from being blocked when Huoyi could not advance or retreat, he would let the army not move, but secretly discharged a partial division to capture the city.

Just when Li Yuan was busy gathering troops and at the same time proclaiming vassal to the Turks in exchange for Turkic support. Chang'an has also been preparing to defend against Li Yuan's attack, and when Li Yuan's army was assembled and finally came to Huoyi all the way west, Chang'an's garrison had been waiting here for a long time.

The dark night rain was dripping, crossing the barracks of Li Yuan's army, in the camp tent, Li Shimin was frowning, staring deeply at a point on the map in a daze, although the road from Taiyuan to Guanzhong was not a smooth road, but it must not become an obstacle to this army, the only pass, only this point, Huo Yi, in front of them, blocked the progress of their army.

At this time, Li Shimin is obviously more calm than before, the frivolity of his youth can no longer be seen in the body of this young man who is not yet twenty years old, at this time he is wearing iron armor, and he is even more heroic, Li Shimin has been staring at the point that represents Huo Yi, and suddenly raised his tightly knit brows, as if he had made up his mind, Li Shimin Huo Di strode out of the camp tent and walked towards the location of his father's camp tent, without any scruples about the weather at this time, and the rain that was dripping from under him.

"Second son, please go back, my lord has been very tired in recent days because of military affairs, and he has fallen asleep at this time." The old eunuch Feng Youyu was persuading Li Shimin, who was standing in front of Li Yuan's tent in front of him, asking to enter, although he also knew that this stubborn child would definitely insist on staying here, but after all, he was a child who grew up, Feng Youyu still wanted to do more of his elder's responsibility.

Like Pei Lian, Feng Youyu was also born in Jinyang Palace, different from Pei Lian's position as a palace eunuch in Jinyang, Feng Youyu is the chief eunuch in Jinyang Palace, the two of them are working together in Jinyang Palace, and after a long time, they can be called very familiar, and later they are also familiar with Li Yuan, as well as Li Yuan's young second son of the hero.

As we all know, Li Yuan is a nostalgic person, so this time Li Yuan raised the flag of righteousness, and old friends naturally want to take care of it, plus Feng Youyu is loyal and honest, which is very in line with Li Yuan's wishes, so he was transferred to Li Yuan's side to take care of his food, clothing and daily life.

You must know that Li Shimin followed Li Yuan to Taiyuan when he was just fifteen, and it has been more than four years now, and Feng Youyu is a eunuch because he is a junior like Li Shimin, and he is very caring for a junior like Li Shimin. He's really old.

Lao Feng, who has felt his old age, is naturally very good to the youth, but this time, even Lao Feng can only helplessly refuse, returning to Jinyang is the result of Pei Lian's joint discussion with adults, and when he made such a decision, he had already been strongly opposed by the young man in front of him, but whether it was for Li Yuan or Pei Lian or even the young man in front of him, Jinyang was their foundation, although the Turkic renegade and Ma Yi Liu Wuzhou's invasion were just rumors, but if the thing was true, there was no way forward at this time, and the old nest of things was wiped out again, The army in front of him is very likely to collapse in an instant, and when the time comes, not to mention the hegemony of the world, even if it can save his life in the troubled times, it will be impossible. Li Yuan is not a timid person, it's just that he always has to think about his family.

Therefore, he finally chose Pei Lian's opinion, and decided to return to Taiyuan to take care of his belongings, and he also knew Li Shimin's temperament, and knew that he would definitely chase after him unrelentingly to put forward rebuttal opinions, so Li Yuan gave an order, "Just say that I have fallen asleep, and no one is allowed to disturb me." That's it, blocking Li Shimin from the door.

"Uncle Feng, just let me go in to meet my father!" In the face of Li Shimin's bitter pleading, Feng Youyu could only turn a blind eye, not only him, but also the guards guarding Li Yuan's door one after another, in order to prevent Li Shimin from rushing in while others were unprepared.

Li Shimin finally ignored it anxiously, and shouted loudly: "Father, I know that you are not asleep in it, my son has something to say to you, this is related to the success or failure of our career, father, please come out and listen to me......" Li Shimin shouted hoarsely, and then, as if thinking of something terrible, Li Shimin cried loudly.

"Father, most of our troops are recruited by the reckless heroes on the rivers and lakes, the reason why they are willing to follow us and force westward is because they believe that we can successfully end the troubled times and achieve great causes, if we don't take advantage of the spirit of the army that has just started now, and seize Guanzhong, once it is delayed for a long time, then the morale of the people will be dispersed, and at that time, our defeat will not be far away, the child thinks of this, and can't help but feel cold all over his body, so father, please don't return to Jinyang, once you turn around, It will inevitably be regretted! ……”

Of course Li Yuan didn't fall asleep, in fact, he hasn't slept well these days, of course, under the influence of Huo Yi's obstruction and various rumors, Daddy Li's spirit at this time is trembling, and it is strange that Daddy Li, who is always worried that his family background has been beaten to pieces, can sleep peacefully. At this time, I heard Li Shimin crying outside, Daddy Li didn't care about it at first, but what to do if it was too noisy, Daddy Li pulled the quilt and tore off two pieces of cloth to look inside his ears, although I can still hear it, but I pretend not to hear it, it's okay! But Li Shimin kept yelling, and after a long time, Daddy Li's train of thought was also bypassed, and he began to think along Li Shimin's train of thought, and then, Daddy Li instantly broke out in a cold sweat.

Li Yuan, who can do the important position of Taiyuan Taishou and has a magical archery skill, is of course not stupid, but because he has too many concerns, he can't take a long-term view, and now listening to Li Shimin's analysis of the stakes, Daddy Li immediately understood the key, where can he lie down, immediately got up from the bed, and at the same time beckoned the guards outside to call his Erlang in and ask him what to do next.

Li Shimin did not disappoint him: "The reason why my father is worried is nothing more than the Turkic breach of the covenant and the eagerness of Huo Yi in front of him, Huo Yi's guard Song Laosheng, arrogant and impatient, can be captured in a battle, and the matter of the Turkic breach of the covenant has not yet come to the accurate news, it is not credible, please wait patiently here for my father, at the latest two days, there will be definite news." ”

Li Shimin's analysis reassured Li Yuan, but then, Li Yuan's face became ugly again: "I'm confused, but the left army has been transferred back by me, and it's too late now." Hearing that the Left Route Army had received Li Yuan's order to return, Li Shimin was indeed taken aback, but soon, he calmed down, "Although the Left Route Army has been broadcast, it has only been on the march for less than a day, I will chase them overnight, I will definitely stop them, ask my father to stab an order arrow, I will go to chase now." Li Shimin got Li Yuan's arrows, and despite the rain that was still falling at this time, he gathered his own personal cavalry and chased after him overnight.

Fortunately, the army on the left only walked a day's journey, and in the continuous rainy environment, the speed of the army was not fast, Li Shimin chased overnight, and finally caught up with this army the next day, and then, this army turned around again and rushed in the direction of Huoyi again.

When Li Shimin caught up with the Left Route Army, the grain and grass baggage, which had been delayed because of the rain, also happened to rush to the position of the Left Route Army and met with them, and the news brought by the baggage team made everyone's mood relaxed: as Li Shimin expected, the Turkic breach of the contract was really just a rumor, and the continuous rain also converged at this time, and finally stopped very much in the evening of this day.

The next day, the rain stopped, the bright sun shone on this rain-irrigated land, the army stationed under the city of Huoyi also walked out of the slump for days, re-glowing with vitality, the soldiers grinding their fists and clapping their palms, the fighting spirit was raging, it seemed that at this moment, there was nothing to stop their progress, and the Huoyi in front of them, as well as Song Laosheng who blocked them in the city, will be crushed in front of this powerful army.
