The Yanzi River is in the territory of Guangshui, and there are only a few places suitable for crossing the river. After Shengbao raised troops to the Yanzi River, the first thing he did was to demolish the only stone bridge that communicated the two banks, and at the same time began to build a camp in a dangerous place.

Whether it is better for the Tang army to rebuild the bridge, or to collect ships and build rafts, it will not be able to succeed in a short period of time, as long as the warning time is early enough, it will be too good to attack half-crossing. No matter how fierce the Northern Tang army is, under such natural geographical advantages, can it still grow wings and fly over?

General Xiang Zhen's tens of thousands of reinforcements are about to arrive, and when this army comes, the Southern Alliance army assembled in Guangshui will be as many as 100,000. Completely take Guangshui, then defeat Shi Zhuang of Xinyang, and then take Xinyang by the way, then Eyue will be stable.

After all, the Tang army on the opposite side was only thirty or forty thousand.

With several times the number of troops, there will be a hard shock, who is afraid of whom?

Katsubo is easy.

Liang Han is also very relaxed.

Although the dark clouds overhead, the wind gusted in my ears, and I saw that the weather was getting worse little by little. Thousands of horsemen were resting in a valley, and the soldiers were eating their second meal of the day, the first of which had been hastily stuffed into their stomachs when they set out in the morning.

Thousands of people gathered, but they couldn't hear the slightest noise.

The perfect logistical supply of the Northern Tang army enabled these soldiers to get full nutrition even during high-intensity marching.

The dried meat wrapped in butter paper is a little salty, pour water into the fried noodles, stir it, then pour the packet into it and stir together, and finally cut the dried meat into small strips with a knife, and a dinner that is not delicious, but absolutely satisfying.

And before they ate, their beloved war horses had already been properly prepared. After eating, he wrapped his cloak and fell asleep.

The soldiers only need to fight, while the generals have more to do.

Under a big tree, a glass lamp with a cover illuminated Fang Yuan a few steps, and Liang Han was eating the dried meat with a knife while looking at a map of Guangshui in front of him.

"Are you sure you're building a bridge here?" He looked at one of the generals in front of him.

"The scouts have already gone to investigate, and after excluding several places where the Southern Army is preparing to cross the river, this is the most suitable place." Zhu Fei said.

"The current is a little faster!" Liang Han said.

"Our engineers went into the water to probe, and the water flow was indeed a little fast, but it had not yet reached our limit, and the deepest part of the water here was only more than ten meters."

"I'll give you half the night at most!" Liang Han looked up at the sky, although he couldn't see anything. "It takes time for you to get there, it takes time to build a bridge, and if you can't build it at night, you won't be able to hide it during the day, and when the army of Shengbao arrives, our efforts will be in vain."

"Enough time in the middle of the night!" Zhu Fei was full of confidence, "Such a river is not a big river, with our latest technology and bridge-building tools, it is very fast." ”

"That's okay, you go and get busy, I'll set off at the fourth watch, and at dawn, my army will finish crossing the river!" Liang Han stretched.

"Yes, I'll go." Zhu Fei also didn't drag his feet, stood up, chewed the dried meat in his mouth, and turned to leave.

Zhu Fei's confidence comes from the latest technology and craftsmanship of the Northern Tang Dynasty.

By the Yanzi River.

The soldiers of the Northern Tang Dynasty, who arrived at the river at night, unloaded bundles of objects from their horses, pulled them apart on the edge of the river beach, spread them on the river beach, and then, finding the air intake from the four corners, stuffed a pipe into it, and one soldier began to hold a tube-like thing, where it was pressed up and down.

Rubber began to be officially put into military production in the Northern Tang Dynasty.

Rubber pontoons are the latest production.

And this pump in the hands of the soldiers is also another derivative product from this.

With the efforts of the soldiers, the rubber bags that had been shriveled and spread on the river beach began to bulge. It wasn't until an officer climbed up and jumped on it vigorously for a long time that he jumped down and waved his hand in satisfaction.

The cheering soldiers immediately pulled out the air intake, sealed the air intake, and then carefully wrapped it tightly, and then the four soldiers pulled up the four corners, and lifted the big thing, which looked big, but was not heavy, and carried it into the river.

A soldier came up with a steel drill, put it in a ring in a corner, and then forcefully inserted the steel drill into the sand, and then another soldier came up with a sledgehammer, and several hammers went down, and the four steel drills firmly fixed the rubber pontoon to the river.

The second one was hooked up.

And then the third, the fourth.

There are few other differences other than the longer and longer drills that hold them in place.

The rubber pontoons slowly stretched out above the river, and the bridge-building activities did not end there.

Iron rods were tied horizontally to the steel drills inserted into the riverbed, connecting the individual steel drills to give them a stronger ability to hit the water current, and on the rubber pontoons, iron bars were also laid one by one, and finally, there were wooden planks.

About 500 soldiers, each on their own duty, methodically extended the bridge over the Yanzi River towards the opposite bank.

At this time, Shengbao, who was sleeping soundly in the camp, could not have imagined that someone could build two bridges across the Yanzi River in the middle of the night.

It's hard to blame him.

Because this is completely beyond what he has known about war in the past few decades.

The application of new materials in the Northern Tang Dynasty basically appeared first in the military, and only through this cruel war can the ability of new materials be more recognized by ordinary people.

At the fourth watch, Liang Han woke up from his sleep, stood up and rubbed his face, already in good spirits, "All of them are here, ready to go!" ”

Thousands of cavalrymen got up from the ground in a hurry, inspected their horses, inspected their armor, and everything was ready, and they turned over their horses in unison, followed Liang Han towards the point of crossing the river, and walked away slowly.

The sky is slightly bright, and the two bridges across the Yanzi River have been completed, separated by more than 100 steps, towering majestically above the river.

In the distance, more than a dozen scouts of the Southern Army Alliance were slowly riding their horses, saying that they did not return to the camp until midnight yesterday, at this time, they were all sleepy-eyed, sitting on the horse or couldn't help but doze off, their heads up and down like chickens pecking rice, and they walked forward completely by the reins.

The leading one reined in and looked into the distance in disbelief.

"What's that?" He asked in a trembling voice.

More than a dozen people looked in the direction pointed by the leader's arm, and in an instant, everyone's drowsiness was not flying, and they were all excited.

What is that?

They had been patrolling here yesterday afternoon, and when they came and went, there was nothing bare above the river, and now there were two bridges.

Yes, those were two bridges.

"There are ghosts!" A soldier's voice suddenly shuddered.

If it weren't for the ghosts and gods, how could it be that two bridges were erected over the Yanzi River overnight.

"It's not a ghost, it's a northerner!" The soldiers at the head of the group looked at the Datang flag fluttering on the bridge deck, and they had already reacted, and at this time, someone over there had obviously discovered them, and dozens of cavalry had already ridden towards them. "Let's go, go back and tell General Sheng that the northerners have crossed the river!"

More than a dozen scouts turned around and rode away.

When the scouts of the southern army fled in the direction of the camp, Liang Han had already arrived at the Yanzi River and personally rode up the pontoon bridge. The bridge sinks slightly, floating slightly, but thanks to the steel drills that hold the pontoons on both sides and the iron bars that connect them, the shaking is not too noticeable.

With his legs clamped, Liang Han accelerated across the pontoon, and then ran back again.

"In a group of ten, cross the river quickly!" Liang Han waved his hand.

Although he tried it himself, Liang Han was still cautious, riding across the river in groups of ten, and walking from one end to the other was just a few breathing hours, and it didn't take much effort. He didn't want everyone to rush up, if something happened to this thing, it would be too late to cry.

Liang Hanzhi watched triumphantly as his cavalry crossed the river and assembled on the other side of the Yanzi River, while in the Shengbao camp, Shengbao, who had just gotten up and had not had time to wash, looked at the scouts who fled back in panic in amazement.

"Bridge? Or two-seater? The Northern Tang army was crossing the river? He subconsciously asked, but his eyes revealed complete disbelief.

After receiving the scout's affirmation, Katsuho jumped up at once, rushed out of the big tent, and shouted: "Beat the drums, assemble, and the whole army will leave the camp." ”

At this point, Katsuho made a mistake, and his scouts fled in disarray before they could fully find out the details of the other party.

When people are terrified, they tend to ignore something more important.

Katsuho didn't ask how many people there were in the army and what kind of troops.

If he knew that it was the cavalry of the Northern Tang Dynasty and all of them were cavalry, he would never have given up the camp so hastily. At this moment, his mind was full of rushing over quickly, and then half-crossing.

The enemy will not cross the river so quickly, and it is likely that he will still have time.

Of the 5,000 soldiers and horses he commanded, 4,000 were foot soldiers and 1,000 were cavalry.

And his opponent, Liang Han led a full 5,000 cavalry.

When Shengbao's army hurriedly left the camp, Liang Han's 5,000 cavalry had already completed the river crossing, and the two armies were moving in the opposite direction, approaching rapidly.
