"Report, general, a team of 10,000 people in front of the Huns is already ten miles away on the south side of the river, and there are boats constantly throwing into the river for pontoon bridge!"

Dozens of miles outside the middle acropolis, Zhang Han has led 30,000 soldiers and horses in it, inside the military tent, the sand table is cast, with the entire Beidi County as the center, the big river on the west side is clearly visible, and the subtleties of the big river can also be glimpsed.

The Acropolis is the most prominent place to the west of Beidi County, therefore, compared with Jingyuan City, it is the goal of the Xiongnu and others, not only that, but the original is the case, the width of the big river outside the Acropolis is slightly slower than other river sections.

The narrowest part of the area, only thirty zhang or so, is the place where the scouts reported in front of them, and since ancient times, when large armies want to cross the river, small rivers are just a breeze.

But a river like a great river cannot be built without a pontoon bridge, but a large number of boats are connected horizontally across the river, and wide and flat planks are built on it, so that a bridge floating on the river is achieved.

Enough to pass through the army and all the siege engines they carried.

Not surprisingly, the Xiongnu took the lead in building a pontoon bridge.

"You stand down first."

Zhang Han was wearing light black light armor, carrying a long sword, and waved his palm at the man, this matter was expected by himself, since he wanted to cross the river, he definitely wanted to find the narrowest area.

There...... It's a good fit.

However, with a width of only 30 zhang, it is not necessary to use too many boats, with the means of the Mo family, if there is no obstacle, it is easy to build a pontoon bridge, and when the time comes, the follow-up army of 200,000 can come quickly.

Hearing this, the scout saluted and hurriedly retreated.

"What do you think?"

In the military tent, in addition to Zhang Han, the general of the garrison of the six passes, there are also the original people who are guarding the six passes, and the generals and Sima Duo are in it, all of them are wearing armor, standing around the sand table, and they can't stop looking.

"General Zhang, now that the Huns and other pioneers want to cross the river, we naturally want to suppress it with strong bows and crossbows, so that their pontoon bridges cannot be built!"

One pointed to the main point of the big river on the sand table, but it was the narrowest.

It is not so easy to build a pontoon bridge on a river thirty zhang wide, despite the help of the Mo family, if they really want to stop it, at least in a short period of time.

Even if it succeeds, it will not be a great price.

"In addition, the last general thinks that those Huns mostly grow on the grassland and are not accustomed to water, so we can select soldiers in the army who are familiar with water and destroy those pontoon boats."

"Let its 200,000 troops not be able to pour into the Zhongwei City at once, and here, Longxi is rich in fierce fire oil, and the pontoon bridge on the big river is quite conspicuous, and it is directly attacked by fire."

For many years, sitting in the six passes of Beidi County, a military general naturally has his own ability, hearing Zhang Han's words, he did not dare to slack off, and in the Zhongwei City not far behind him, Wu Zhenhou himself.

There was a saying before, if there is merit, all will fall, if it is damaged, no one can escape.

In this way, how dare you not rack your brains.

"The last general thinks that with the location of the big river, you can also use the water attack method when the three Jin countries destroyed Zhi Boyao, and the source of the big river can be traced on the side of Jingyuan City, and a high embankment can be cast to accumulate water potential, and sure enough, when the Huns forcibly build a pontoon bridge, they can also go down with water potential and directly wash it away!"

One person whispered that the battle on both sides of the river was naturally indispensable for the strategy of water attack, and in any case, the 200,000 troops west of the river would have to pay a great price if they wanted to cross the river.

Maybe...... Eventually, they will come, but they will also weigh whether it is worth it.

"The last general thinks that the words of several generals are enough to deal with the Huns to build a pontoon bridge and want to cross the river, in addition, sure enough, the Huns force to cross the river at any cost, then, we can also use the big river as the border to lay down a line of defense."

"Trench excavation, dense traps, supplemented by other strategies, the general will think that those Huns want to really come to the front of the Acropolis, without the cost of tens of thousands of people, it is absolutely impossible!"

One person came out of the ranks, looked at the rest of the people on his side before, and smiled slightly, since he wants to defend, then ...... It is necessary to have a defensive strategy, and the Acropolis is a hundred miles away from that narrow place.

It's easy to lay out more than three lines of defense.

"Good."

"What the general thinks, he probably can't come up with these, even so, each leading his troops and horses, thinking that he is hindering."

A smile flashed on Zhang Han's face, those strategies can be used, as long as they have an effect, they can be used.

The Xiongnu had a total of 200,000 troops, and if they really wanted to forcibly cross the river, it would not be difficult, but they would have to pay the price of tens of thousands of people, and the Central Acropolis had already laid out a defensive strategy.

Just waiting for the Huns and others to come.

Sure enough, being able to defend it is a great achievement.

The final round is set.

"Whoa!"

“……”

The generals clasped their fists and saluted, and each of them went down as he had previously commanded.

******

"Giant, there is news from the front, when a team of 10,000 people in the vanguard wanted to build a pontoon bridge in the narrowest part of the river, they were blocked by the military forces of the Qin State, suffered heavy losses, and the wooden boats were damaged a lot."

It is only more than 100 miles away from the Central Acropolis, and the 200,000-strong army is mighty, constantly advancing along the road on the edge of the desert.

Zhang Jingfang is one of the leaders of the Mo family, the original disciple of the Mo family of Qi State, followed the giant to the west of the river, for nearly a year, and finally got something.

"The big river is a river that is as famous as the great river of Zhuxia and Chu State, even if it is narrow, it is not easy to cross."

"Jingfang, you can go later."

The method of crossing the great river has been considered by myself before, and I have already made a decision, although it also has to pay some price, but ...... It's a bit delusional to want to get over without paying the price.

The method of crossing the river has been told to Jingfang, and the road pillow waves wrapped in black clothes are also worry-free.

"Yes, giant."

Zhang Jingfang was right, although he was a little reluctant, but he ...... After all, the disciples of the Mo family shed too much blood in Beidi County.

Immediately, as expected by the giant, the envoy of the right virtuous king of the Xiongnu came and summoned the Mo family and his party.

The giant had no time to pay attention, so Zhang Jingfang and the two Mo family disciples went.

Half an hour later, the three of them joined another team of 10,000 men, and hurried to the place where the river was, hoping to quickly build a pontoon bridge for the army that was about to arrive, otherwise the river would not be able to cross, why should the army come to the city.

"Commander, although the big river is narrow here, it is no less than thirty zhang when viewed visually, and it is already rare in the hinterland of the Central Plains!"

Three hours later, the Mo family and the Xiongnu pioneers, who were the first to go to the side of the river, looked at each other and couldn't stop talking to each other.

Although the Huns are not proficient in the language, they are still clear in simple rhyme.

"Here...... It is already the westernmost side of the border of Qin, with two layers of protection of the big river and the Great Wall, whether it is the Xiongnu, or the country of Yueshi and Wusun, it is very difficult to attack Beidi County and Longxi County. ”

"If the army wants to attack the Acropolis, it must cross the river!"

The terrain here is relatively gentle, and within the big river, although the water flows towards the north, it is not urgent, which makes the three Mo family feel a lot more at ease.

With such a form of river, it is much more convenient to build a pontoon bridge.

However, on the river, there are some fragments of residual wood floating, not surprisingly, it should be that when the pontoon bridge was built before, it was destroyed by the Qin army on the opposite side, but despite this, a large amount of wood was still taken from nearby to cast large and small wooden boats.

"Tell me to go down and connect all the ships together, and now it is the end of the hour, it is the height of summer, and the night is quite bright, but it is no longer bright, and when the time comes, it is a matter of building a pontoon bridge."

"And ...... Mobilize two 3,000-strong archery teams on the left and right, hold the powerful bows and crossbows given to them by our Mo family in the army, and press the formation to pave the bridge! ”
