Shi a didn't set out with the army at last. After detailed introduction of the situation of the cities with Lu Zhong, he immediately led people to set out ahead of time. In addition to dozens of shadow guards, Lu Zhong also selected dozens of elite soldiers from the Iron Eagle elite. They drove more than 20 carriages with some grain and articles from the warehouse of gaopingguan, The motorcade, dressed as a merchant in Gaoping pass, set out first to prepare for the capture of the city by the army.

Half an hour later, Gaoping pass had all fallen into the control of Lu Zhong. He immediately ordered the army to rest for a while. After that, he left 1000 iron eagles to defend the pass. Then he led 5000 cavalry and 8000 iron eagles to continue to set out in the direction of Wei.

An hour later, when Tian Yu led the Chinese army to gaopingguan, the former army had disappeared. Looking at the direction of Wei's family in the East, Tian Yu couldn't help laughing bitterly. Although he was the chief General of the army, he was working as a logistics general to finish for Lu Zhong's former army. However, this situation had been predicted at the beginning of the war. After all, the war was over The goal is a strategy: fast.

The army of Tian Yu didn't stay in Gaoping pass for long. Instead, after counting all the equipment in Gaoping pass, they put all the Zhao prisoners in custody. They carried the equipment and continued to go in the direction of Wei. The forward army was light and fast. In case the forward didn't steal the city smoothly, the equipment he carried could just play a role. Of course, Tian Yu also hopes that his layout can not be used.

……

At the beginning of the war in gaopingguan, hundreds of miles south of taihangxing tianjingguan, another war also began.

Taihangxing, also known as taihangdao, is an important channel connecting Jincheng city and Jiaozuo City in ancient Chinese history. It starts from Qinyang, Jiaozuo, Henan Province in the South and connects Zezhou County, Jincheng City, Shanxi Province in the north. It is famous as "the first place for soldiers" and "the thoroughfare for business". According to historical records, from tianjingguan, Zezhou County, Jincheng city to Taihang Road between Changping village, Qinyang City, Henan Province in the south, the mountain roads are winding like sheep intestines, and the passes stand like stars, so the geographical location is very important. Tianjingguan, in particular, is a famous pass in the world. The ancients said that "the shape of the world, dangerous pass pressure Taihang.".

Taihangxing ancient road is more than 100 kilometers long, and the most dangerous part is the section from Changping village to tianjingguan in Qinyang. Among these 40 Li, taihangxing rises from the Qinhe plain to the top of Taihang with a relative height of more than 1500 meters. It passes through steep mountains and steep waterfalls, which are actually dangerous passes.

In the game, taihangxing is also a dangerous ancient road. In the north, it starts from tianjingguan in the south of Gaodu County, and in the south, it is a pass called Wankou city in the north of yewang county.

Today's tianjingguan is controlled by the Zhao army, while the city of Wankou is in the hands of the Tang army. The two families occupy both ends of the stone road.

Just when Lu Zhongbu's army began to attack gaopingguan, the vanguard Hanoi's army led by Dong Xun also arrived in the south of tianjingguan and began to attack tianjingguan. Of course, their attack was not a surprise attack, but a ready attack. The purpose was to attract the troops of tianjingguan and Gaodu to this area and provide help for the army of Tianyu.

At tianjingguan, Zhao's General Hu Cai looks at the Tang army coming from outside the pass. The dense number of taxi soldiers makes him feel numb. As early as two days ago, he wondered why there were so few business trips these days. If it was a day, although it was not as good as the two years when Zhao and Tang had a close relationship, there were always people coming and going every day One or two small caravans passed through kaijingguan.

However, in the past two days, even a caravan did not appear under tianjingguan. Although it had happened before, it usually happened when the road was snowed in winter. For example, it is September now, which is the best time to walk on the road. Therefore, Hu Cai specially sent people to Guannan for inspection, but he didn't find anything unusual. Of course, these soldiers didn't dare to go through the ancient road tens of miles long and run to the bottom of Wankou city to inspect.

I didn't expect that this morning, just as he was about to open the gate, the commander on duty suddenly found that there were a large number of Tang soldiers outside the gate. He was so scared that he sat on the wall. You know, although the relationship between the two families was not very good, they didn't get the news that the two families were enemies.

In fact, they didn't know. Just now, well, it was just now. On September 10, shortly after daybreak, the Prime Minister of Tang state announced a king's order when gathering officials for discussion, that is, Lv Bu, the king of Zhao. He has no ability. If Xianbei invades Bingzhou, the people of Yanmen and Daijun will suffer heavy losses. However, the king of Zhao does not know how to reflect, instead, he will destroy Xianbei The reason for the invasion of the people to the South was framed by the domestic Taishou. For such a non German monarch as him, Emperor Huangfu Chaobo of the Tang Dynasty decided to send troops to punish him.

Well, that's probably what it means. However, the imperial edicts written by everyone CAI are parallel, which makes Huangfu Chaobo dizzy. However, after reading them by Tian Feng and Zhu Jun, they all praise them. So Huangfu Chaobo directly used the seal on them and handed it to Tian Feng.

Nowadays, although the world's vassals are constantly fighting, they generally pay attention to a well-known one, such as Gongsun Zan, who even conceals his own prime minister and captain. It's really a shame to send troops to sneak attack.As soon as the Tang state's call for Zhao came out, the whole world was in an uproar. All the princes did not expect that the Tang state should send troops to Zhao at this time. A few days later, when Lv Bu got the address from Huangfu Chaobo, he was so angry that he jumped to scold him. They did not expect that Huangfu Chaobo would attack him for this reason.

When Hu Cai saw tens of thousands of Tang troops outside the pass, he immediately ordered to close the gate and summon the soldiers inside the pass to mount the pass wall to prepare for the attack of the Tang army. At the same time, he immediately sent people to the Gaodu city and the eldest son city behind tianjingguan.

Shangdang county is the third largest county under Bingzhou, with a population of more than 200000, but Zhao's army in Shangdang is 40000 or 50000. It's just that there are too many places to be garrisoned. There are 13 cities, and three of the eight Xings in Taihang are located in Shangdang. They are fukouxing, Baixing and taihangxing, all of which need to be garrisoned by a large army. If it is spread out equally, there will be 5000 people in each of the three passes, 10000 people in each county, and only 2000 people in the other counties.

Hu CAI was in a hurry to Gaodu, but he didn't expect that all the troops would come to support him. He also knew that only the ten thousand garrison in the eldest son's city could send reinforcements in Shangdang. Oh, if you add the one thousand soldiers of the prefect and Duwei, there are twelve thousand in total. I only need to hold on for three or five days, and the commander's army will surely come.
