After learning about the situation in Shangdang, the troops continued to march north. From Danzhu Ridge, a narrow path is lowered into Shangdang. Hu Yang saw that there was a small gathering on the side of the road, and there was no city, so he asked Gao Dushou without words: "What is the name of the city?" ”

Gao Dushou seemed to be familiar with it, and replied: "The city of Gaodu, where Rong Di lives, has a vague name. This town lives in the mountains and flatlands, so it is called Changping. ”

Hu Yang said casually: "If you build a fortress here and defend it, you can't open it!" ”

Gao Du Shou said: "As Zhong Geng said. ”

Not far from Gaodu to Shangdang through Changping, there is a city built on the mountain, which is the city of the eldest son. The Shangdang County Guard is stationed here. Shangdang Shou and Gao Du Shou are not more than 100 miles apart, once sometimes, the two sides can support each other through the mountain road under the Danzhu Mountains, and they are also very familiar with each other. Shangdang Shou has already been informed by Gao Dushou that the army will enter Shangdang today. Early in the morning, Shangdang Shou, together with all the officials, lined up outside the city with a thousand soldiers to wait. Seeing the army coming out of the canyon, he drove forward and shouted, "The party is guarded and welcomed!" ”

The former army commander of Han came up to pay a salute, and was led by the party officials to set up a camp; Then came out the former army of the Qin army, the main general Wang Yi. He didn't know Jin Yin very well, but fortunately, there were people among the party officials who understood Qin Yin and made a translation. Led by the officials, they went to the lower camp. However, Wang rejected the address indicated by the party officials and chose a mountainous area to set up a camp.

Mountains and valleys are taboo on the march, must be passed quickly, and must not be camped in them. Therefore, after the front army left the valley, the middle army and the rear army only advanced a distance respectively, and stopped in front of the canyon to camp. Gao Dushou informed Shangdangshou of the situation of the Chinese army and the rear army, and asked Shangdangshou to prepare three days' worth of food.

The next day, Shangdang Shou led the troops in front to lead the way, and the front armies of Han and Qin advanced in turn, one on the left and one on the right. Heading north along the river, after a day, stop at a wide flat river. Shangdang Shou told Wang Yi that this place is called Tunliu. From tomorrow, we will go on the mountain road.

Later, Gongzi and Hu Yang led the Chinese army, and Sima Jin, the general of the Qin army, entered the camp under the eldest son city yesterday. The left-behind officials of the eldest son diligently served grain and syrup. There were many streams in the place he passed, and Hu Yang asked, "Where does this stream go out of the mountain?" ”

The official replied: "All the waters are the source of the Zhanghe River, and the mountain will flow into the Zhangshui." All the streams of Zhangshui come out of this mountain, if the mountain rainstorms, the Zhangshui under the mountain overflows. Everyone is a turtle. ”

Hu Yang said: "The source of Zhangshui, apart from the eldest son, where is it?" ”

The official replied, "The eldest son is full of water." …… The general wants to cut down the water and also flows into Zhangshui, which is the source of Zhangshui. ”

Hu Yang said: "Han and Zhao Shanchuan are connected and converge from the same source. Once attacked, how sad is it? ”

The official was not afraid that Hu Yang suddenly asked such a sentence, and he didn't know how to answer, so he had to use his words to diverge.

After the official left, Hu Yang called Zheng Anping and Chen Si and asked them to take a dozen or so people to probe downstream along the direction of the river to see if there was any place to ambush the army, and to observe the terrain of the mountains and rivers along the way. In the middle of the night, the two reported that the water was downstream and passed a waterfall, and it was unlikely that a large number of troops would come up from this side. Hu Yang nodded slowly.

On the third day, Hu Yang also walked up the mountain road from Tunliu. Although the road had not been easy to traverse since entering Taihang, the road was more difficult to follow than before, and finally stopped in front of a valley and entered the camp set up by the former army.

Hu Yang asked the liaison officer of his eldest son as usual, what is the name of this place? The liaison officer replied: "It is named Nirvana, there is water named Wuxiang, and it is also injected with Zhangshui." From here, there are high mountains and valleys, and it is difficult to walk, so it is a day to rest here. ”

Hu Yang asked again: "Where will you go back to the water in Wuxiang?" ”

The official said: "Tracing the water will come out of Taihang and smear the water; Out of the mountain is Taiyuan. ”

Hu Yang said: "This Nirvana leads to Taiyuan on the left, Handan on the right, and it really chokes Zhao's throat!" ”

The official said: "Taiyuan and Handan are connected to the party. Zhao extinguished Zhongshan, and its way was easy, so Zhongshan was the dry, and the party was the last ear. ”

Hu Yang has a deep sense of conspiracy! He didn't know where this feeling came from, so he had to send a sentry to the upper and lower reaches of Wuxiang Water, and he took advantage of the fact that it was still early to lead Sima Jin, Ye Yi, Zheng Anping, Chen Si and others to climb high and look far away. The mountains are steep everywhere, and if they set up a heavy ambush in the canyon, they will not survive. However, there is a scene of jackdaws returning to their nests, the sun is setting, and the canyon is quiet. Wang Ji of the former army sent an envoy every other hour to report back, and the former army did not find out about the situation.

Hu Yang set up camp at the mouth of the canyon and controlled the high ground on one side. He was thinking, if he attacked Yan He and Zhao Jun suddenly sent troops from Taiyuan to rescue, how long would it take? Will you have time to get out, or will you set up an ambush in the canyon? What if the Zhao army in Taiyuan controlled the exit of the canyon and did not fight with him?

He discussed it with Sima Jin, Ye Yi and others, and they also thought so. But because of the complete lack of familiarity with geography, these ideas can only be utopian, and there is no solution for them, and they cannot be abandoned because of them. In the end, everyone reluctantly came to the conclusion that even if there was such a risk, they could only go into it.

Sima Jin suggested: "You can order the Houjun Wang's Mausoleum to stay at the mouth of the valley and spy on Taiyuan." But if you get it, you will report it urgently. ”

According to the scheduled itinerary, the rear army has just walked out of Danzhuling and reached the eldest son. It is basically impossible to call him over for discussion. Moreover, there are not only Han troops but also Wei troops around the royal tomb, and the situation is the most complicated, and it is basically impossible to leave a covering force in concealment. What's more, Nirvana is remote and sparsely populated, so it is useless to have fewer troops, and more is perceived by friendly forces, not to mention, supply is also a problem. Thinking about it, there is no particularly good way.

The troops patrolling the posts up and down gradually returned, and all reported no signs of enemy activity. The uneasiness in Hu Yang's heart could not be dispelled: going deep into the depths of Zhao and fighting a small Juyi, what intention did South Korea want to achieve?

After receiving the task of attacking Yanhe, Hu Yang did his homework, but the dungeon or remote, there was not much information, only knew that the terrain was dangerous, but the population was not large, and it was estimated that the army would not be too strong. In Qindi, you can't even find too many specific situations. This time, the three kingdoms of Qin, Han, and Wei gathered an army of about 100,000 men, which may be more than the entire population of Yanhe. Why did such a small town spend so much strength to fight? The eldest son of Korea is at least three days away from here, and he has to go to Yanyu, and I heard that he will have to walk for another five or six days, and it is all mountain roads. Wouldn't it be worth the loss to overcome so many difficulties to fight an unimportant city?

After many days of marching in the mountains, coupled with the severe cold weather, soldiers were constantly sick. Hu Yang's Chinese army continued to contain sick soldiers who had fallen behind from the former army, some of whom could follow the Chinese army on the road, and some of them might have to wait for the rear army to contain them, or even have to stay by themselves, and then chase after the troops when their health permits.

Zheng Anping, like other soldiers, set off with a ten-pound fried corn bag on his back. There were basically supplies along the way, and dry food was basically not used. Unlike the military soldiers in Weidang, the Qin army did not have heavy leather armor, which lightened a lot of burden, but also felt a little lacking in courage. In the past, he dared to face the blade, almost relying on the protection of leather armor. Now that he is only wearing regular clothes, I am afraid that a stray arrow can hurt him. The winter clothes prepared before the trip are freshly sewn and very warm. The bad thing is that when I was wading through mountains and rivers, I sweated all over my body and it was difficult to breathe, so I only wore it for a day, and then I put it in my bag, and I only used it as a blanket when I slept in the open.

Since entering the mountain, Zheng Anping found that Chen Si's body seemed to be in trouble. went to ask himself, but Chen Si refused to say it, and asked him not to make a fuss. Zheng Anping was afraid that Chen Si would be tired from walking the mountain road, so he took his dry food bag and carried it himself, Chen Si repeatedly refused, and Zheng Anping almost grabbed it.

Barely supporting the campsite, Chen Si did not rest, but as usual, drew the situation of the mountains and rivers he saw along the way. These days, he has to paint one every day, and he already has more than a dozen. Zheng Anping saw that he was still drawing maps as usual, and felt that there might not be anything serious. I didn't ask any more, I made him a handful of fried corn to eat, left the bag of dry food with me, and continued to help him carry it tomorrow.

After two days of camping on the mountain road, on the third day, a plain finally appeared in front of me, and a clear mountain stream flowed through it. This is also a basin formed by the alluvium of the river, Shangdang Shou introduced, this place is named after the water, called Yi, and then over the front of the mountain, it will reach the Yan. Wang and the former commander-in-chief of the Korean army assigned their respective defensive directions, and decided to set up their camps near the confluence of the two rivers by sending their own guards north along the main rivers. At the same time, a signal was sent to the Chinese army: it had reached within 100 miles of the distance and asked for further action plans.

It was already midnight when Hu Yang got the news. After receiving the report from the front army, he instructed the front army to occupy all the surrounding points and wait for the arrival of the Chinese army. At the same time, people were sent to inform the rear army that the front army had arrived in the vicinity of Yanhe and should be vigilant. Then ask the commander of the Korean army, Gongzi, to discuss the matter in the battalion.

Childe was able to persevere on the rugged mountain road, and he had already done his best. Stay in the camp, eat a little and fall asleep. Hearing that Hu Yang was coming, he only called one retainer to listen to the order in a daze. Hu Yang knew that Gongzi was to blame for everything, but he was actually to the retainers, although he was unhappy, he was helpless. He simply informed his retainers that the former army had reached Yi, less than a hundred miles away. He planned to go to Yi tomorrow to inspect the situation, and the advance of the Chinese army should be vigilant, be on guard, and guard against a sneak attack. The retainers should be answered one by one.

In the early morning of the next day, Hu Yang led his own battalion of 600 people to advance quickly. The Chinese army, under the command of Gongzi and Sima Jin, advanced with alert movements, and the speed was greatly slowed. It was already dusk when they arrived, and the rear army had already entered the camp, and the camp was strengthened and the guard was strengthened.
