"That's not!" Hearing Chen Xuanli ask this, Fan Zhicheng was taken aback, quickly shook his head and denied it, and explained stubbornly: "Tongguan must be rescued, but the opportunity for the army led by the general to enter Tongguan City must be grasped!"

"Well, this matter will be known, you have to say it again, beware of people's ears!" Chen Xuanli said that he no longer paid attention to Fan Zhicheng, and after a whip and "driving", the horse ran away.

Fan Zhicheng and Chen Xuanli's personal soldiers immediately followed.

beheaded Bian Lingcheng in public, raised his sword again, gained people's hearts, and won the respect of the generals, Yang Xi's mood was much better.

However, he knew that the situation had not been reversed, and in the current situation, our army was still at a disadvantage, and the rebels were in an absolute advantage, and if we wanted to reverse the situation, we must either strike a strong blow at the rebels and annihilate the living forces of the rebels in large numbers, or the follow-up army would arrive as soon as possible, otherwise the situation could not have changed fundamentally. In the first few ambush battles, Ling Cheng could only play a role in boosting the morale of the army and increasing his prestige, but could not fundamentally solve the problem of guarding Tongguan.

A large number of annihilation of the rebel army's living forces, this may be possible, but at the same time, the strength of our army is definitely attrition, even if the proportion of loss is much smaller than that of the rebels, but it is also a loss that cannot be beared, to completely reverse the situation, we can only hope that the follow-up reinforcements will arrive as soon as possible to strengthen the defensive force. The defensive forces are sufficient, relying on the terrain advantages inside and outside Tongguan City, it should be easy to block the rebels outside Tongguan City. Yang Xi very much hopes that the reinforcements will arrive soon, so as not to fall into the hands of the rebels!

He once again sent a letter asking for help through the post station, asking the imperial court to send reinforcements as soon as possible, send more reinforcements, and urged Chen Xuanli to speed up the march and strive to reach Tongguan as soon as possible. Such an urgent report for help was prepared to happen every two hours, and threw the problem to Li Longji, the emperor of Chang'an, and his father Yang Guozhong, the prime minister!

The rebels were attacked by a medium-sized fire, suffered a certain amount of losses, and retreated for more than ten miles, but Yang Xi knew that this was only a temporary situation, and as the mountain fire gradually extinguished, the rebels would definitely attack again. It is impossible to set a mountain fire again, from the east to Tongguan, only that place is full of vegetation, other places are sparse, want to set fire can not be put up, at most pile some hay, quickly burn out, even if you can set a mountain fire, it may burn to the side of Tongguan City, so that Hantong Guancheng, Twelve Liancheng and Xintong Guancheng are damaged.

The rebels will surely attack again during the day or evening today, and fierce fighting will inevitably break out!

The prophecy was soon fulfilled, and just when Yang Xi was hiding in the city gate tower and eating a bowl of mung bean soup sent by the sergeant to relieve the heat, the sergeant sent out to inquire about the situation sent back an urgent report that the rebels had invaded again!

"Report to Yang Soldiers and Horses, the rebels are pulling out again and coming in the direction of Tongguan!"

"Prepare for battle now!" Yang Xi, who was startled, immediately put down the dishes and chopsticks, and ordered the sergeants and soldiers to prepare for battle!

The speed of the rebels is so fast, it is estimated that there is still more than an hour before dark, it seems that the rebels have plans to attack the city at night!

Yang Xi once again stood on the gate tower of the east gate, looking out at the situation in the southeast direction.

Although there is no air pollution at this time, there is no haze, and a bright sun shining on the earth makes the sight super good, and you can see the scenery dozens of miles away, but you can only see it, and you can't see it clearly. The scale of the rebels' march and the specific movements of the rebels cannot really be seen, only a vague approximation.

He was in dire need of a telescope, a telescope that could see things in the distance, and that he could stand on the tower and see the situation in the distance.

Special forces are versatile and have super hands-on skills, and of course Yang Xi can assemble a simple but usable telescope by himself, but he needs to have materials. During the break just now, he had ordered Yang Zheng to go to Tongguan City to collect transparent things such as crystal or glass, and make them into a certain curvature according to his instructions, and he was ready to assemble a usable telescope by himself, but this idea may not be realized.

Now there are only sergeants in Tongguan City, the people have almost escaped, from Chang'an to Tongguan on the official road, you can see the fleeing people everywhere, Yang Xi led the army to rescue Tongguan, was blocked on the official road, the speed was delayed mainly because there were too many people fleeing, there were not many sergeants who fled to Chang'an through Tongguan, look at the number of sergeants Liu Guangting finally collected!

The people in Tongguan City have almost escaped, so it is very difficult to find crystals or glass. Yang Xi knew a little that glass was still a very precious thing, rarely seen, and the fineness was not good, what could be easily obtained should be a crystal with similar light transmittance as glass, but there were only sergeants left in Tongguan City, and it was very difficult to search for crystal or glass as soon as possible, at least for now.

There was no way to get a telescope, so Yang Xi could only observe the situation with his own eyes, and analyze and judge the enemy situation in combination with the situation transmitted by the spies or observation posts in front.

From the analysis of the situation he found, he came to the conclusion that the fierce battle under the Hantong Pass would break out in half an hour.

What he hopes now is that the more than 2,000 men led by Pang Zhong and Li Fu can hold on to the Hantong Pass for a longer time, and the worst result will be until after dark. When it gets dark, it will be detrimental to both the offensive and defensive sides, but the men and horses led by Pang Zhong are very familiar with the situation in this area, and they are much stranger than the rebels.

If he can hold out until after dark, it is basically impossible for the rebels to attack the Suitong Pass where he is standing this night, and the rebels can only arrive at the Sui Tong Pass tomorrow at the earliest, and the rebels' attack on the Sui Tong Pass will be delayed for at least one night, or even longer.

However, Yang Xi would not let all the more than 2,000 men and horses die on the Hantong Pass, and he was ready to withdraw this man and horse after fighting with the rebels besieging the city, so as not to lose too much, resulting in insufficient defensive forces in the Sui Tong Pass, and damaging the morale of the whole army.

If the Hantong Pass City was attacked by the rebels and all the defenders above were killed, it would be a very big blow to the morale of the defenders of the Tongguan City he was currently guarding, and it might even cause riots. A few small victories in the morning boosted morale, and the morale of the army was cohesive to a certain extent, and Yang Xi didn't want to let this morale be exhausted with the death of thousands of people.

The Suitong Pass City, which is now guarded, is the most dangerous place in the entire Tongguan Pass, and the final defense is to devote all the troops to defend in the most dangerous place. The Hantong Pass was already very dilapidated and could only be used as a point of defense, not as a final point of entrenchment.

The Sui Tong Pass City is several times more dangerous than the dilapidated Hantong Pass City!

Yang Xi knew that he was not good at how to command large-scale corps operations in the era of cold weapons, and he needed further study and exploration. But in the current situation, he knew that the only thing he needed to do was to try his best to hold Tongguan City and prevent the rebels from occupying this gateway to Chang'an, and the arrangement he wanted to make was completely centered on this purpose!

Yang Xi's orders also quickly reached Pang Zhong and Li Fude through the sergeants.
