Luonan Road, the confluence of Luoshui and the Great River, is an important waterway connecting Guanzhong and the Yellow River, and it is also an important hub for the Qin army to transport grain and grass through the waterway, that is to say, if Luonan Road is controlled, the Qin army will not be able to transport grain and grass from Heluo to the main position of the Mengfu army outside the river through the Yellow River.

At this time, the boats on the river were passing back and forth, and the Qin soldiers and the recruited people were busy unloading the grain and grass to the wharf on the bank of the river, and everything was in order.

"General, this batch of newly arrived military rations has been counted, a total of 100,000 stones, and it can be shipped the day after tomorrow." A potato warden said to Qin Jianghuan.

"Great, but remember, nothing can be wronged." Huan Wang Huan Lu commanded, he didn't dare to be sloppy in this matter, otherwise once something went wrong, even he couldn't afford to be guilty.

"Don't worry, general!" The potato officer bowed down and promised.

At this moment, I heard someone shouting in the distance: "Look, what is that?" ”

I saw a puff of smoke and dust billowing in, and everyone followed the prestige, only to see hundreds of armored soldiers on war horses galloping towards them, they were holding spears and wearing iron armor, and they were fierce.

"What is Wei Jun?!" Huan Qi was shocked, how could this Wei army suddenly appear here.

"Kill!" Ji Huan, the commander of the Wei Wushu Huozi Battalion, raised his spear and took the lead in rushing over, the good horse under his crotch flew like an arrow from the string, and it was close in front of him in an instant, Ji Huan roared and swung the spear to stab, and the spear shot out like a dragon, and immediately the first few Qin soldiers were pierced through the body, and fell to the ground with a scream.

"Kill!" A group of knights followed, and the spears in their hands stabbed at the Qin soldiers like poisonous snakes, and one by one the Qin soldiers were pierced through their bodies and died on the spot.

"Close the gate for me!" Seeing this, Huan Qi hurriedly shouted.

"But what about the soldiers and the grain and grass outside?" The potato officer asked with some hesitation.

"I can't do so much anymore!" Huan Qi gritted his teeth and said.

"Quick! Crossbowmen prepare! Shoot me! Don't let this group of Wei knights break through the walled gate! Huan Qi shouted loudly.

The Qin soldiers quickly gathered, set up bows and shot arrows, and the dense arrows poured towards the Wei knights.

Suddenly, the knights of the Wei Kingdom were knocked over by the dense rain of arrows.

"Withdraw it for me!" Ji Huan hurriedly stopped his subordinates and used the lives of his own group of cavalry to fill this camp, it was unwise, he was unwilling to send his subordinates to death in vain.

Huan Qi was relieved to see the Wei army retreating, but he was afraid that this might just be the vanguard of the Wei army.

The group of Wei knights did not retreat far, but hung out of the range of the Qin soldiers' bows and crossbows, staring at the Qin army like wolves.

He didn't dare to open the gate of the wall, so the entire Qin army was divided into two parts: outside the wall and inside the wall.

After a while, I saw a crowd of people surging on the mountain road in the west, waving flags, and the black pressure was overwhelming, and it was actually an army of tens of thousands of people coming here.

"It's the Wei army, our army is finished!" Huan Qi looked at the scene in front of him and his face turned pale.

"The general might as well take advantage of the fact that the Wei army is not encircled now and kill it." The potato officer said.

"If you lose the Luonan River, even if you escape, you will die,

It's better to fight with the enemy! Huan Qi said, he has the will to die, since he can't escape, it is better to fight with these Wei soldiers, this is the only thing he can do.

At this time, a group of Wei soldiers outside the village was lining up, and the commander of the Wei army was Wei Wuji, the king of Xinling, and his eyes were staring at the Qin army's walled gate.

"The army has been arrayed, General, do you want to attack the village?" The lieutenant general beside him asked Xinlingjun.

"Order Ji Huan to lead two battalions of soldiers and horses to prepare to attack the Qin army on the riverbank." Xin Lingjun said.

"Push the catapult forward." Xin Lingjun said again.

This stone-throwing is a catapult built by Fu Nian to Xinlingjun's suggestion to Xinlingjun to build local materials.

Artillery has been in existence since the Spring and Autumn Period, and this time it is just an improvement on the original basis.

This kind of traveling artillery cart can use two other pillars to erect the cannon when in use, and the wheels are separated from the ground, which not only makes the cannon stable, but also increases the height of the cannon. The power and weight of the projectile are not as good as those of the stationary cannon, but they are much more convenient.

I've seen the magic of the public loser before, and his little thing is a little worthless.

This world is very different from the pre-Qin era of the original world, not only has a martial arts system, similar to the black technology of the machine-like beast, but the development of the entire army has also reached the level of the Tang and Song dynasties.

For example, this is a very obvious army armor rate, and almost all of the armies of the seven countries have been armor along the way. On the other hand, there is cavalry, which has become more popular than the same period in the original world, and has developed equipped cavalry.

Fu Nian checked the cables, winches, and cannons of these catapults.

Compared with the human projectile of this era, the elastic projectile is a big progress, but this simple version of the catapult, whether it is a bracket or a winch, is a wooden imitation, and the stability and durability are not high.

According to the weight of the catapult, the tensile force of the winch should generally be 1.5~2 times of the weight of the car, and the weight of the catapult is about 100 kg, 100x1.5÷0.453=331.13lbs=1490N.

In other words, the maximum projectile weight of this catapult is about 150 kg - 200 kg.

The Wei sergeant had already begun to load the catapult according to the order he had given him.

Fu Nian used tree branches to calculate on the ground, ballistics calculations are a very complex project, and at the level of this era, the parameters that affect ballistics are also immeasurable for him. For example, the friction coefficient of air in the low subsonic state is greatly affected by temperature, humidity and air pressure, which can only be estimated and cannot be accurately calculated. The most important thing is that the working state of the self-made trebuchet varies greatly, and the dispersion surface of multiple throws is also large, and it is difficult to calculate the trajectory of such an unstable system.

However, Fu Nian is not impossible, he has done ballistic sampling tests before, and made several ballistic tables through bullet impact samples. A two-dimensional table was made with different power outputs as rows, and the corresponding landing distance was made for the column.

He now only needs to determine the projectile and throw angle adjustment at a known distance from this table to get a roughly precise landing point.

"Brother Fu, what are you doing here?" Zhang Tantou and the others came over and asked puzzledly.

Fu Nian shook his head slightly, and said, "I'm just calculating the landing point." ”

"I don't know any of that, I don't know what you're going to have in your head." Zhang Tan scratched his scalp and smiled honestly.

Fu Nian ignored him and continued to list formulas on the ground.

Yu Chan'er ran to Fu Nian's side with a curious look, she saw these things similar to ghost paintings for the first time, just looking at Fu Nian's serious expression, she inexplicably had a feeling of worship in her heart, and involuntarily followed Fu Nian to learn.

"On 100 catties of stone bullets, the bars and heavy objects rotate 85 degrees, and the ground is 40 degrees." After Fu Nian calculated the three paradigms, he got up and commanded the slinger.

Although these soldiers didn't understand what Fu Nian meant, Fu Nian had taught them how to do it before, and they were still prepared according to Fu Nian's orders.

Fu Nian checked and adjusted the angle of the slinger one by one before the slinger was ready to throw.

"Put!"

With a command, the stone bullet flew out and smashed straight towards the wall, instantly hitting the wall, and the stirring dust drifted everywhere.

The Qin soldiers who were guarding looked at the billowing smoke and covered their noses.

After a while, the smoke and dust gradually dissipated, and the Qin army and everyone saw clearly that the wall had sunken down, revealing a huge ravine, and if the stone bullet just now hit them, they would definitely be crushed.

All the soldiers of the Qin army looked frightened.

The flying stone was thrown again and smashed into the Qin army's array.

For a time, the Qin army was in chaos, and many people were smashed and their flesh and blood flew sideways, wailing all over the field.

"Crossbowmen ready!" Xinling Jun Wei Wuji said in a deep voice.

The archers of the Wei army had already set up their formation, their bowstrings were taut, and with the order of Xinling Jun, they suddenly loosened their bowstrings.

The arrows pierced the sky and flew towards the Qin army on the opposite side like a horse.

The shield bearer of the Qin army immediately raised his shield to block the arrows that were fired, only to hear a few muffled bangs, and the arrows pierced through the shield and inserted into the chests of the Qin soldiers, and the blood flowed down the wounds, staining the armor red.

Huan Qi's face was gloomy, looking at the Wei army in the distance, his fists clenched, and he couldn't wait to rush out and fight with the Wei army.

Another dense rain of arrows struck, and the Qin army's array was suddenly in chaos, and many people were shot and killed before they could dodge.

Although the Qin army fought back sporadically, it was particularly vulnerable in the dense rain of arrows.

"Pass my order, the whole army presses up, and the camp is ready first." Seeing that the time was ripe, Xinlingjun gave the order for a general attack.

Following Xin Lingjun's words, the Wei army began to slowly approach the wall.

Ji Huan on the left flank took the lead and led the knights of the Huozi Battalion towards the Qin army on the riverbank, he brandished his cavalry gun and shouted.

"Charge!"

The Wei army roared in unison, the war horses neighed, and rushed towards the formation of the Qin army.

"Shieldman! Shieldholder! ”

One shield after another was combined into a military formation, which firmly protected the Qin army, and the soldiers of the Qin army held the weapons in their hands tightly and waited for the battle.

"Kill!"

With a sharp roar, the spear went out to sea like a dragon, and suddenly stabbed out, with the power of ten thousand jun, the momentum was like a thousand catties, the shield was picked up, and the Qin sergeant was overturned.

The spear stabbed out again, and two more people were knocked to the ground.

The Wei cavalry rushed to the front of the formation, and they held spears in their hands, drove straight in, rushed into the Qin army's formation, and slaughtered them in a big way.

The shield array of the Qin army immediately collapsed, and the soldiers kept screaming and being picked up and stabbed to death.

As the Wei infantry entered the battlefield, the Qin army on the banks of the river collapsed on all fronts.

"200 pounds of stone bullets!" Fu Nian readjusted the angle and axle moment of the catapult, and once again ordered the catapult to be thrown.

The boulder roared out and hit the wall of the Qin army, and with a loud bang, the wall collapsed, killing many soldiers.

The Wei army in the rear took the opportunity to launch a general attack and rushed towards the wall.

"Quick! Plug the gap! Huan Qi shouted loudly, he took his own soldiers, armed with long knives, rushed to the front, and fought bravely.

Huan Qi took the lead, cutting down a Wei soldier with a knife, followed by another slash, cutting down the Wei soldiers who were the first to the ground.

"Qin Dog! Eat your grandfather and I'll stab you! Zhang Tan jumped up, picked up the long knife and slashed towards Huan Qi, his knife was extremely powerful and imposing.

Huan Qi hurriedly greeted him with a knife, with a sound of the bell, the long knives collided, Huan Qi was shocked and took two steps back, the tiger's mouth in his hand cracked, and the blood dripped and dripped, barely catching Zhang Tan's knife.

"Humph!" Zhang Tan snorted coldly, and a strong wind whistled.

He only felt a white light flash in front of him.

"Poof!"

A sharp blade pierced through his body, peeking through his back.

Then another knife was made, and a head was thrown high and fell to the ground.

The rise of Zhang Tan's killing directly rushed into the enemy formation, cutting melons and vegetables to harvest the lives of the Qin army......

Xin Lingjun came to the bank of the Luo River, looking at the grain and grass piled up at the ferry, he couldn't help but sigh.

"We have succeeded in this first step." Fu Nian saw that Xinlingjun seemed to be worried, and said softly beside him.

"What do you think I'm going to do next?" Shin Ling-kun looked up at the mountains opposite.

"Since you should cut down wood as a boat, control Luonan Road, and cut off the supply of grain and grass for the Qin army." Fu Nian said.

"Not bad." Xinling Jun Wei Wuji nodded approvingly.

"But the most important step depends on the news from General Pang Xuan and Sister Ji and the actions of the farmer." Fu Nian said again.

"Han Gongsun Ying is a person who knows the soldiers, I don't think he will refuse, but don't be careful about the actions of the farmer."

Xinling Jun Wei Wuji pondered for a moment and said, "Yanran's side is the most critical player in this game of chess, now you just have to wait." ”

The main reason why he traveled so far to cut off the grain and grass of the Qin army was to prevent the Mengfu army from coming to the rescue, and at the same time bypassed King Hanye and Wu Sui, and cut off the supply of grain and grass to the Qin army without blood.

Luoyi, the camp of the Qin army, Wang Qi was sitting in the tent, he looked at a letter in front of him, his brows were tightened, and his expression was quite serious.

"How could this Wei army appear in Luonan Road, so that the waterway from Heluo to Guanzhong will be completely blocked by the Wei army!" Wang Qi said worriedly.

"Immediately order the whole army to stop transporting grain and grass from the waterway, and the various departments will not be able to hold out, and order Hei Bingtai to send a letter to General Mengfu with a red fire seal to send a message to General Mengfu to return to help, and report the matter of this place back to Xianyang, and report it to the Lord Xiangguo."

"Whoa." The pro-soldier next to him promised and left quickly.

His gaze was constantly changing, cloudy and uncertain.

Wei Bing got the grain and grass of Luonan Road, and his previous strategy of fortifying the wall and clearing the wilderness has gone bankrupt, and now he can only respond to all changes with the same.
