Yang Xi was worried about when the reinforcements would arrive, and some of the reinforcements were also hoping to reach Tongguan as soon as possible.

Dou Hua and Zhang Yan, who were in the first place, both gave death orders, asking the sergeants to march as fast as they could.

"Report to the general, there are a lot of fleeing homeless people in front, blocking the official road, and the speed of our department is blocked!"

A sergeant quickly ran in front of Dou Hua, who was running in the middle with his personal guards, and reported the situation loudly.

"Got it!" Dou Hua, who was slowing down his mount, frowned, and ordered loudly without hesitation, "Order, immediately disperse the refugees on the official road, if there is anyone who obstructs the road, there will be no forgiveness!"

"Yes, General!" The sergeant who reported loudly went to convey Dou Hua's order.

With Dou Hua's order issued, there was a scene of chickens flying and dogs on the official road, and the soldiers of the Tang Army who were galloping quickly waved their bright swords, shouted loudly, ignoring whether there was anyone blocking the road in front of them, and continued to run at a fast speed. If any ignorant person still walks in the middle of the official road and obstructs the march of the official army, then the sword in their hand will be waved down immediately.

These are the people who fled from Tongguan and the vicinity of Tongguan to Chang'an, occasionally mixed with a small number of routs, these people have already become frightened birds, seeing the army running fast in the distance, most of the people automatically hid on the side of the road, let the road out, and did not dare to fight with the sergeants.

But there are always people who are slow to react, or have difficulty moving, and have no time to dodge when the sergeant is running quickly.

In any era, survival of the fittest is an immutable law, this law is applicable to most situations, even when fleeing, the refugees who are slow to react or have no time to dodge have mostly become victims of the Tang Army sergeants who opened the way, and they were also cut if they did not die, and some of the seriously injured and fell to the ground were trampled by the follow-up war horses, and they died with a whimper.

No one paid attention to these unlucky eggs, and the murderous Tang soldiers still ran forward quickly, hurrying in the direction of Tongguan.

However, the number of displaced people fleeing on the official road was still quite large, which more or less affected the speed of the army's march.

And the damn weather, which affects the speed of the horse's travel.

The speed of the men and horses was not as fast as expected, Dou Hua, who led the army, was anxious, Yang Guozhong's repeated instructions before leaving, and the tragic situation of Tongguan in his imagination appeared in his mind from time to time, so that he couldn't wait to let these thousands of men and horses put on their wings and fly to Tongguan City immediately to join the ranks of blocking the rebels.

Although the men and horses led by Dou Hua belonged to Chen Xuanli's backup army, they were almost half a day earlier than Chen Xuanli's follow-up army. Before Dou Hua led the army to set off, Yang Guozhong gave a death order, asking Dou Hua to march as fast as possible, even if half of the soldiers died, he had to find a way to reach Tongguan as soon as possible.

Under heavy pressure, Dou Hua could only make the soldiers of the whole army march at the fastest speed they could achieve, but the refugees who appeared from time to time on the official road, as well as the scorching hot weather, made people feel that they had more than enough strength but not enough strength.

The physical strength of both men and horses must not be exhausted, otherwise it will be counterproductive, and after running a certain distance, it is always necessary to slow down or take a temporary break, otherwise many people and horses will die. Although Yang Guozhong ordered that even if half of the men and horses were killed, they should arrive at Tongguan as soon as possible, but Dou Hua, who was in charge of leading the army, knew that in many cases, it was not possible to reach it if they wanted to hurry, and in order to let these 3,000 men and horses have the strength and strength to participate in the battle of defending the city on a large scale after arriving at Tongguan, they must reasonably allocate their physical strength, have proper rest, and maintain the speed that the men and horses can bear, otherwise they will really kill half of the men and horses, and the remaining half will not be able to enter the battle.

Dou Hua was very eager to have enough war horses like Yang Xi's department, so that they could move forward in turn, but because there were not enough horses in Chang'an City, he wanted to follow Yang Xi's move and had no chance to achieve it, you must know that the 60,000 army led by Chen Xuanli still had nearly 10,000 horses to ride, so they could only walk.

"The ideal is very plump, the reality is very skinny", this may be the feeling of many people now, although Dou Hua is anxious and wants to Tongguan as soon as possible, but he is still muttering in his heart, if he does not let Ge Shuhan go out of the pass to fight, then there will be no current critical situation in Tongguan, and there is no need for Yang Xi and their follow-up people to rescue in such a hurry, Lingbao fights, but all the soldiers and horses near Tongguan and Tongguan are filled in.

After running fast for a while, Dou Hua also slowed down the sergeant and found a way to get people and horses to come in to replenish food and water.

At this time, the emergency report from Tongguan for help was sent to Chang'an again through the fast horse of the post station, and the three arrows and red ribbons inserted on the backpack of the sergeant's rescue emergency on the horseback were particularly eye-catching, and there was a shocking feeling.

The sergeants who reported the news galloped over, whether it was the fleeing civilians or the sergeants led by Dou Hua, they all avoided and did not dare to fight with them.

This is already the third batch of fast horses that Dou Hua encountered after setting off from Chang'an, looking at the sergeant who galloped to deliver the emergency military report, Dou Hua's heart was very heavy, of course he imagined how critical the military situation in Tongguan was, and immediately called the deputy general around him to ask where he had gone now, and how long it would take to reach Tongguan!

"Report to the general, we have just left Chang'an for seventy miles, and we can reach Weinan before dark. If you rush overnight, you can reach Tongguan at noon or afternoon tomorrow at the earliest!"

The adjutant general's report made Dou Hua's mood heavy again, and after he stared at the queue marching in the distance for a while, he shouted again, "Order the whole army, rest at the post station in front, replenish drinking water and food, and after the rest is completed, speed up and march, rush overnight, and no longer be able to rest!"

As he spoke, he whipped his whip and drove his horse forward. The adjutant general quickly passed on Dou Hua's order.

Dou Hua's troops were advancing rapidly, and Zhang Yan, who had set out from Chang'an an an hour later than him, also ordered his subordinates to march at the fastest speed they could.

Zhang Gradual, like Dou Hua, is also Yang Guozhong's cronies, they were promoted because of Yang Guozhong's appreciation, they have a kind of gratitude to Yang Guozhong, this time Yang Guozhong ordered them to lead the army to first aid Tongguan, and asked in person. How dare they be careless and delay, of course, they are to do their best to fulfill Yang Guozhong's entrustment, arrive at Tongguan as soon as possible, and give Yang Xi reinforcements.

Zhang Yan, like Dou Hua, stayed in the army for a long time, but he still had some experience in how to lead the army, knowing that in this kind of hot weather, if he ran with all his might, it would make many people die of horsepower, so he did not make his subordinates run continuously with all their strength, but asked the soldiers to march quickly at a speed that both men and horses could eat, and prepare to speed up after the weather was cool at night, and continue to advance without rest.

Different from Dou Hua and Zhang Yan's anxious mood, Chen Xuanli, who led the follow-up reinforcements to the direction of Tongguan, was not very anxious, he had the kind of thinking about the benefits of the fisherman, and he did not make the soldiers run with all their might, in comparison, the speed of the follow-up reinforcements was much slower than that of Dou Hua and Zhang Yanbu, not to mention those infantry troops who had no horses to use, and they were dragging behind!

Fortunately, Yang Xi didn't know the situation of the follow-up reinforcements, and he didn't know Chen Xuanli's mentality at this time, otherwise he would have gone crazy with anger!
