As a result of the Zhao army's inspection, the Great Wall had been occupied by the Qin army, which had collected hundreds of boats and was ferrying across the river day and night.

Lian Po was shocked when he heard the news: the Great Wall is the first line of defense in Handan, with Zhangshui as the pool, the city is ten zhang high, and there is Yecheng on the other side of the river as a barrier, which is difficult to overcome from the south normally. But if it's better than the north...... To the north is Handan, the object of the Great Wall's protection! Who will defend against an attack from Handan?! Lian Po's hair was fried, his body was cold, and he was sweating all over. In any case, the battle of Zhao was lost badly: Qin had clearly found another way to attack Zhao: from Shangdang to Wu'an, and to the outskirts of Handan! On this road, Handan has almost no danger to defend and completely opens its doors! Hu Yang only used 20,000 troops (this is the news he got from Zhao Hao) to successfully stir up Handan, and he was about to retreat!

Fortunately, the Qin army is crossing the river, and if it rushes to the Great Wall quickly, it can just be attacked halfway, and that is the weakest moment for the Qin army!

Lian Po ordered his troops to advance in turn, and they must reach the outside of the Great Wall before dusk.

The place where the garrisons of the Great Wall were stationed was called Wucheng, and it was a huge city with a circumference of ten miles. In peacetime, it was stationed in troops, and in wartime, it was a stronghold to guard the Great Wall on the first line of Zhangshui. The surrounding Wucheng is densely packed with lakes and swamps, and the rivers are criss-crossed, which is extremely inconvenient for large armies to fight. If there is a strong enemy, even if he continuously conquers Yecheng, crosses the Zhangshui, and breaks the Great Wall, he will fall into the rivers and lakes, and the Wucheng built on the hills is the first nail to be removed by the enemy. The so-called Great Wall area is actually a lake and marsh area surrounded by half of the city wall. For the enemy forces coming from the south, this is a trap.

However, the Qin army, which attacked from Wu'an along the water, did not have such trouble: they went down the river and rushed straight into the city. The surrounding waters instead hindered the movement and concentration of the Zhao army, and although the guards of Wucheng spotted them and raised the alarm, they did not have time to shrink enough troops; Even though Wucheng was strong, unguarded was just a decoration, and under the attack of the superior forces of the Qin army, Wucheng collapsed without actual battle.

Sima Jin set up a big tent in Wucheng, controlled the boats on the Fushui and Zhangshui rivers, and became his own tool for maneuvering. The Qin people from Jingwei and the banks of the Yellow River, there are many rowing masters, and they are now elected to be responsible for driving the boat. If the original owner is willing to serve, he is also allowed to act as a deputy. After mobilizing enough ships, Sima Jin quickly transported 5,000 men to the other side of Zhangshui, and fought across the river.

At dusk, Wang Yu arrived with 5,000 men from the front army; Two hours later, a prince came with 2,000 men, including Gongzi and his sons, as well as Bing Cao and some of the Qin people who were lurking. Sima Jin sent an envoy to find Hu Yang, reported the news of the arrival of Wang Di, Gongzi Zhang, and Bing Cao, and said that he had sent troops to seize the other side of Zhangshui, and the retreat of our army had been opened.

Wang Ji conveyed Hu Yang's opinion: after striking at the Zhao army on the front line of the Great Wall, he should cross the river. The strengthened Qin army has now reached 17,000 people, except for 5,000 on the other side of Zhangshui, which is not suitable for mobilization for the time being, and the remaining 12,000 people are waiting for work to deal with the 30,000 Zhao army, and everyone feels that they are still sure.

In the Great Wall area, the water is an important geographical factor, which traverses the entire lake and marsh area, is navigable, and is the center of gravity of the entire Great Wall area. Needless to say, everyone's thoughts naturally revolve around the water.

Bing Cao lurked around Handan in Zhao State for half a year, and the focus of reconnaissance was naturally Handan and the Great Wall. Although he has been probing many times, it is still difficult for Hyocao to grasp the mystery. He spread out his sketches of the Great Wall around the Great Wall among the crowd for everyone's reference. But to be honest, it is not easy to read through the map in a short period of time. Therefore, everyone still looked at Bing Cao, ready to listen to his opinion.

Bing Cao said: "Wucheng faces south, which can be described as solid; And the north is not enough to take it. Sima's trip can prove it! The minister thought that it was the best policy to cross the water in Yingzhong, enter Wucheng, and cross the Zhangshui to the south. Fighting along the water and attacking the Zhao army in Banji is the middle strategy. Attacking the Zhao army over the water is a next step. ”

Sima Jin said: "Sun Tzu said, know yourself and know your opponent, and you will not be defeated in a hundred battles." The minister thought about it, if the Zhao army came north, what plan would it be to attack the southern army? ”

Bing Cao said: "I would like to hear the opinions of the five doctors." ”

Sima Jin said: "Non-ministers can know." Ranchen has ordered his family and documents to choose the books of Wucheng and watch them all. Or there is something to gain. He took out a diagram from his bosom, spread it out in front of the banquet, and said, "Princes, take a closer look, what does this picture mean?" ”

Bing Cao, Gongzi Xuan, and Wang Yi all came to him, and everyone couldn't understand it. This is a map, and a map of the terrain around the Great Wall, as everyone knows. However, everyone is not familiar with the terrain, and it is difficult to match the situation of the mountains and rivers on the map with the real world; Second, the text in the picture is Zhao Shu, which is very different from Qin Shu, and no one here has studied Zhao Shu, so everyone can't understand it. I once thought about finding a translator for Zhao Ren, but it was not easy to find someone who could understand the voices of Zhao and Qin. Although Bing Cao and Gongzi Xuan and others have been lurking in Zhao for half a year, they are almost equivalent to illiterate, and they can only speak Zhao Yin and do not understand Zhao Shu. Bing Cao suddenly thought that Zhonglang was "Zhao Guotong", and proposed to invite him to come over to discuss, which solved the problem.

After the pawn Zhonglang came over, he glanced at the map and said, "It's the situation map of the Great Wall." Then he read out the annotations on the map one by one. Everyone vaguely felt that this might be a map of military deployment. Everyone, you and I guessed every word until the early hours of the morning, and then we roughly figured out the general meaning of this picture: this is the plan map for the reinforcements of Handan when the Great Wall was attacked.

Knowing this was very exciting, and it meant that Lim Po might also be able to move his troops in accordance with this deployment. In the middle of the discussion, the sentinel came to report, and the fire broke out in the distance, as if there was a shout. Wang Ji sent additional sentry to patrol the place where the fire started, and if there was any need for support, he would report back immediately.

Bing Cao looked at a corner of the map and said: "The Zhao army may come out of here, and immediately go to it to see the terrain and prepare for its battle." ”

The crowd agreed. So everyone ignored the fatigue of sleepless nights and went forward.

Since most of the Great Wall is wetland, it is not suitable for large forces to fight, so there are only a few battlefield options. When the Zhao army was in a defensive position, it was prepared to close these exits, trap the invading enemy army in this lake and swamp land first, unable to move, and then gradually mobilize troops to annihilate them. And the situation of the Qin army was that the Zhao army, which wanted to attack the Zhao army that came to reinforce it, completely reversed the offensive and defensive momentum. However, the generals of the Qin army were limited by their understanding of the terrain around the Great Wall, and could not consider the problem as a whole in a short period of time, so they could only grasp one of the points and make breakthroughs. So, they chose the location along the avenue among the several assembly points marked on the map, on the grounds that Hu Yang would definitely follow the most obvious avenue into the Great Wall, and Zhao Jun would definitely follow Hu Yang.

When we arrived at the Fushui River, it was already dark. Sima Jin sent an army to contact Hu Yang to report that the rear army was currently about ten miles away from Zhao's army and about ten miles away from Fushui; Hu Yang continued to harass the Zhao army at night, and after preparing to fight the Zhao army in the early morning, he retreated to the Great Wall, and asked Sima Jin to wait for them to prepare boats and pontoon bridges by the Fushui River.

The facilities for crossing the water are ready-made: because this is the main road from Handan to the Great Wall, there are strong bridges built on the water. The boats were already controlled by Sima Jin and were ready-made, and the pontoon bridge was easy to build. But where the most important thing is to attack Zhao Jun, Hu Yang did not mention. After field exploration of the terrain, there is no hidden terrain to set up ambushes, and there is no commanding height to occupy. In the end, everyone reached a consensus: to set up a formation by the Fushui River, and to kill and wound the Zhao army when they cross the river, it will definitely be able to severely defeat the Zhao army's spirit.

After the plan was roughly determined, each began to mobilize troops: 1,000 people were responsible for receiving Huyang to cross the river, and after crossing the river, Huyang's troops retreated to Wucheng; 10,000 troops were arranged by the river, leaving 2,000 to defend the city. Wucheng is about twenty miles away from the shore of Fushui, and Hu Yang's troops can reach it in about an hour, so that the defending force of Wucheng will reach 5,000 people, which must be foolproof.

Since Sima Jin's 5,000 men had already reached the other side of Zhangshui, these operations were mainly based on Wang Ji's front army of 7,000 people, and Sima Jin's rear army of 3,000 people as backup.

Wang Di's former army arrived at the Great Wall at dusk yesterday and did not enter Wucheng, but camped on the road from Fushui to Wucheng. After dawn, the army gathered and ordered to set off after breakfast. Five hundred of Wang Di's pro-battalion men set out on the road ahead of time to meet Hu Yang and guide him to retreat; Sima Jin's personal battalion of 500 men was responsible for guarding the bridge, supervising the erection of pontoon bridges, and preparing ships.

Wang Di's camp had just crossed the Fushui Bridge when the sound of drums faintly came from the morning mist. The retainers immediately ordered the pro-battalion to speed up the march and rush in the direction of the drums. After about five or six miles, the drumming in front of me stopped. The retainers did not know the details and did not dare to advance rashly, so they ordered the whole battalion to stop advancing and sent a hundred men forward to investigate and understand the situation; The rest are ready for battle.

The morning fog gradually dissipated, and a ray of sunlight appeared on the horizon, and the distant hills were illuminated by the sunlight and dressed in red. A military envoy hurried back and reported that the Central Guard Department had won the victory, beheading more than 500 ranks, killing and wounding countless enemy troops; The Qin army suffered three or four hundred casualties; Ordered the pro-camp to wait in place and not have to move forward.

Not long after, the camp saw a team appear in the distance, approached from time to time, and the hundred men sent out walked in the front to avoid misunderstandings. The team consisted of about 2,000 men, many of whom were wounded, some of them were more serious, and they were carried forward by others. The retainer ordered the whole army to get out of the way and let this group of Qin troops pass. The two armies met, felt cordial to each other, and shouted to each other.

There is a humane in the pro-camp: "The injury is serious! Don't worry! The enemy will not be able to pass! ”

There is a humane in the rear: "He is already cold, how dare he chase him!" It must be unacceptable! They laughed and scolded each other, jokingly.

The retainer asked, "Where is the middle watch?" “

Qianjun said: "Zhonggen is close to the other!" Pointing back. When the retainer looked forward, another team appeared in the distance.
