Seeing that Hua'an insisted on going to the north bank of Zhangshui to investigate, Wang San had no choice but to agree to lead two hundred personal soldiers to escort Hua'an.

In Hua'an's view, the main force of the Yan army is still far away from Zhangshui, and the forwards who arrived in advance will not have too many soldiers and horses, which will not pose a threat to themselves, and besides, as long as they find danger, they can withdraw the ferry at any time, and then quickly retreat to the south bank of Zhangshui.

It didn't take long for twenty transport ships to sail to the edge of the ferry, and Hua An and Wang San, with two hundred elite cavalry of the personal guard, rushed to the transport ships, and ordered to set off immediately to the north bank of Zhangshui.

In the process of the transport ship sailing to the north shore, Hua An looked at the wide Zhangshui and said softly: "Zhangshui is a hundred zhang wide, if you build a pontoon bridge on it, it will take at least half a day's work!" ”

When Wang San heard this, he nodded and said: "The Yan army is mainly cavalry, and they are not good at building bridges, I am afraid that if they are given a day's work, they may not be able to build a pontoon bridge that runs through the north and south of Zhangshui!" After speaking, he looked at Hua'an.

Wang San is right, Zhangshui is not only wide, but also the speed of the water flow is not slow, which has brought many difficulties and challenges to the erection of pontoon bridges, and only in relatively wide and gentle places is conducive to erecting pontoon bridges, and these places are naturally under the control of the Jin and Wei coalition forces, and the Yan army wants to erect pontoon bridges, it is difficult to avoid the eyes and ears of the Jin army, thus attracting a large number of Jin army defense.

Hua An looked at the golden water and said: "Building a warship is time-consuming and laborious, if the Yan army wants to capture Yecheng in the shortest possible time, it must build a pontoon bridge over the Zhangshui River, which is Murong Ke's best choice." As long as our army discovers the location of the pontoon bridge built by the Yan army, it can make countermeasures and make the Yan army's attempt to cross the Zhangshui unable to succeed. ”

"What the king said is that our army only needs to keep an eye on the movement of the Zhangshui River, and then we can learn about the Yan army's intentions, so that the Yan army will not be able to cross the Zhangshui." Wang San responded.

It didn't take long for the transport ship to arrive at the north shore of Zhangshui, and Hua An and his men and horses rode ashore and ran to a small hill not far from the ferry.

On the hill bag. Hua'an and his party could clearly see every move within a radius of several miles around them. As long as the soldiers and horses of the Yan Kingdom arrive, they can be discovered and prepared as long as they are miles away from the tree.

Hua'an turned the horse's head. Looking at the Zhangshui to the south. He whispered, "It's a good place to be on the high grounds. If Murong Ke used this place as the Chinese army, he would be able to overlook the entire Zhangshui River, so as to better command the army to cross the river and fight. ”

The king thought. Will Murong Ke use this as a location to build a pontoon bridge? Wang San asked.

Hua An thought for a moment and replied softly: "This place has a wide field of vision and is an excellent command position, but our army has the most soldiers and horses on the opposite bank, so it is not easy for this king to judge whether Murong Ke will use this place as a location to build a pontoon bridge. ”

In Hua An'an, in order to confuse himself, Murong Ke will definitely build pontoon bridges in multiple locations at the same time, and in these directions, there may be only one or several places that are really crossing the river, and the rest of the positions are just bluffs, how to judge Murong Ke's real direction of crossing the river, for Hua An, is a huge test, which requires Hua An to have a clear judgment, and the exploration of the scouts under his command must also be as careful as possible, and the slightest clue cannot be missed.

"Order, let the ships at the ferry go eastward and camp at the berth on the east side, and we will also march east along the Zhangshui edge." Huaan commanded loudly.

"Your Majesty, won't this be too dangerous, if the Yan Kingdom striker suddenly appears, wouldn't it be troublesome." Wang San opened his mouth to dissuade.

Hua An waved his hand and said softly: "You don't have to worry, we will march along the Zhangshui and march with the fleet, there will be no danger, in case a large number of Yan cavalry appears, it is a big deal to swim to the south bank of Zhangshui." After speaking, he smiled slightly.

The reason why he wanted to march all the way east along the north bank of Zhangshui was to personally check the geographical characteristics of this area, which location was suitable for building pontoon bridges, and which location was densely wooded to hide a large number of troops.

Along the way, Hua'an did not encounter the Yan cavalry, but found several important areas, on these sections, there is no mark on the existing map, and these important locations, once ignored, are likely to cause unpredictable consequences.

To this end, Huaan marked the characteristics of these important locations on the map that he carried with him at the first time, and prepared to take them back and then carefully deal with them.

After arriving at Bokou, Hua An and his soldiers boarded the transport ship smoothly, and soon arrived at the south bank of Zhangshui, and after some horse galloping, they returned to the camp outside the north gate of Yecheng.

After returning to the camp, Hua An told his subordinate officials in charge of surveying that the map was unclear, and named them to go to the north and south banks of Zhangshui immediately to re-measure and mark the map, and ordered them to carefully mark all the important locations on the north bank of Zhangshui before the arrival of the main force of the Yan army.

After receiving the order, the officials immediately began to prepare, and went to the north bank of Zhangshui as soon as possible, and began to re-measure and mark the terrain on the north bank of Zhangshui.

After a whole day of rapid preparation, the redrawn topographic map of both sides of the Zhangshui River was placed in front of Hua'an, which made Hua'an quite satisfied.

Hua An began to study the redrawn map carefully, and based on the new map, guessed the possible location of Murong Ke's river crossing.

#####

In the Linshui City on the north bank of Fushui, the main army of Yan State has arrived here one after another, due to Hua'an's implementation of the strategy of clearing the wilderness, the people of Linshui City helped the old and the young, and all withdrew to the vicinity of Yecheng, and all the food and items that can be used in the city were also taken away, and the items that were really inconvenient to take away were all burned, so as not to let the Yan army get any supplies.

The main general of the Yan army, Murong Ke, set up a large tent of the Chinese army in Linshui City, and the main army under his command was crossing the Fushui in order, and after crossing the Fushui, they set up camp on the south bank of the Fushui, waiting for Murong Ke to give the order to continue the march.

In the big tent of the Chinese army, Murong Ke began to analyze how to force the Zhangshui crossing, defeat the Jin and Wei coalition forces, and capture Yecheng according to the situation of the scouts in front of him.

Through the scout's investigation, he learned that the Zhangshui was now a hundred zhang wide and several zhang deep, and the cavalry could not cross it directly, and had to rely on transport ships or build pontoon bridges to cross the Zhangshui along the way.

And all the ferries in Zhangshui were all transferred to the south bank by Hua'an, and if the warships were built at this moment, they were afraid that they would have to delay too much time, which would cause a long-term confrontation.

Murong Ke knew that his second brother was a person who was very happy, and he would not give himself too much time to capture Yecheng, so he had to adopt the strategy of building a pontoon bridge.

Building a pontoon bridge that can cross the Zhangshui requires a lot of timber and rope, which must be prepared immediately, and a sufficient number of them must be prepared to build the pontoon bridge at multiple locations in the Zhangshui at the same time.

Murong Ke ordered the reserve army under his command to immediately start preparing a large number of ropes, and asked a team that had already crossed the water to set off immediately to the north bank of Zhangshui, cutting down a large number of trees nearby for the purpose of building pontoon bridges, in addition, in order to facilitate the crossing of small troops, it was also essential to build some small boats.

After giving the order, Murong Ke began to think about the location of crossing the Zhangshui River in the big tent of the Chinese army, and after some observation and thinking, Murong Ke found many suitable locations for crossing the river, and compared the advantages and disadvantages one by one.

"Fourth brother, in all the locations where pontoon bridges can be built in Zhangshui, there are enemy soldiers and horses stationed, it seems that the enemy will defend Zhangshui to the death and prevent our army from crossing the river!" Murong Ba analyzed softly.

Murong Ke nodded and said: "The Jin army is indeed this intention, however, the Jin army has many fortifications, and it seems that there are no loopholes in the defense, but in fact, it is a scattered force, as long as our army concentrates its forces and crosses the river from one direction, it can form a huge advantage, and quickly gain a foothold on the south bank of Zhangshui, and then defeat the Jin army and capture Yecheng."

"The fourth brother has thought about it for so long, and he thinks that it is best to cross the river from where." Murong Ba asked softly.

Murong Ke looked at the map in front of him, and said: "The most unexpected position for the enemy army is the best location, the ferry in the direction of the north of Yecheng is a good choice, our army can cross Zhangshui from here and defeat the Jin army." ”

"Fourth brother, the Jin army has the most soldiers and horses stationed here, I'm afraid that it will be difficult for our army to cross the Zhangshui from here, so let's change the ferry!" Murong Ba shook his head and said.

Murong Ke shook his head and said, "The main forces of the Jin army are all here, I naturally know this, but as long as our army is slightly transferred and the main force of the Jin army is transferred from here, then won't our army be able to cross the river from here?" ”

"The main force of the Jin army will be transferred from here, is the fourth brother really sure?" Murong Ba was a little skeptical.

Murong Ke smiled, pointed to the map in front of him, and said loudly: "This is the Hezhang Ferry, more than thirty miles away from the Yecheng Ferry, on the left and right sides of the Hezhang Ferry, there are more than a dozen positions, all suitable for erecting pontoon bridges, similarly, in the east of the Yecheng Ferry, there are also many locations, very suitable for the army to cross the river, as long as the main force of our army is divided into two roads, marching in the east and west directions, and let the soldiers build a number of pontoon bridges, ready to prepare for the two wings to cross, the main general of the Jin army will definitely be the main force of the Yecheng Ferry, Moved to the direction of the two flanks to block our army's attempt to cross the river, and after the main forces of the Jin army all reached the left and right flanks, our army could take advantage of the darkness to quickly return to the Yecheng ferry and immediately begin to cross the river.
