The big ship slowed down quickly, Yang Yuanqing walked quickly to the bow of the ship, and found that the fleet was still a mile away from the south shore at this time, the charred trees on the shore were clearly visible, and thousands of Tang troops were densely packed on the shore, with bows and crossbows, waiting for the battle.

But the danger at the moment did not come from the Tang army on the shore, but on the surface of the river, there was a thick layer of viscous black oil, and half of the hull of the big boat he was riding had sailed into the black oil ring, and the bow and sides of the ship were stained with black oil.

Yang Yuanqing was secretly surprised, this was his original way to deal with Li Mi, but he was turned against him by the Tang army, but it was night at that time, and it was difficult to find, and now it was daytime, he could get out of danger in time, Yang Yuanqing immediately ordered, "The ship is rampant, leave the oil area quickly." ”

The big ship slowly turned around and sailed sideways to the east, only a moment, the big boat that Yang Yuanqing was riding left the oil slick area, he looked back and looked around, and several warships parallel to his big ship had also left the oil slick area, but the ships behind were coming in a steady stream.

Yang Yuanqing immediately decided, "Ignite the fire and burn the oil!" ”

The order was given, and dozens of rockets shot at the oil slick on the river, and the oil slick 'Boom!' The ground burned, spreading rapidly, and black smoke billowed so that the surface of the river, which was close to the south bank, was a sea of fire.

The burning surface of the river was the best warning, and the southbound boats stopped moving on the river to wait for the fire to subside, and the fire burned for nearly an hour before it gradually went out.

The flotilla began to regain its strength and move closer to the shore, and for a time the arrows rained down, and the two sides engaged in a fierce battle at the Mengjin ferry.

"Stop the Sui army!"

Wang Huaiwen, the commander-in-chief of the Tang Army, shouted loudly: "The enemy army is not allowed to go ashore!" ”

The Tang army garrisoned more than 5,000 people, 3,000 crossbowmen and 2,000 cavalry at the Mengjin ferry, and they poured thousands of barrels of fire oil on the river outside the ferry, forming the first line of defense, and then deployed 3,000 crossbowmen on the shore, when the Sui warships slowly docked. The Tang army on the shore fired a flurry of arrows. A dense rain of arrows rained down on the big ship, interspersed with countless rockets.

The Sui army on the warship also launched a counterattack, and the arrows rained down. Shooting towards the shore, it was the ship's stone cannons that were more powerful, accompanied by a loud crashing sound. Dozens of pounds of stones smashed into the Tang army on the shore, almost every boulder smashed over several people, there was a scream on the shore, and the Tang army's crossbowmen suffered heavy casualties.

Under the dense offensive of stone artillery, the Tang army's bow and crossbow army was forced to retreat, and there was an opportunity to land on the shore, Yang Yuanqing watched the battle situation on a large ship behind, and he had already seen about two thousand cavalry lined up hundreds of paces away, obviously preparing to launch an attack on the landing Sui army.

"First five hundred heavily armored Mo sword army!"

Yang Yuanqing's order has been given. The flag on the main ship waved, and the two warships carrying the Modao soldiers were the first to dock, and the five hundred heavily armored infantry held the Modao in their hands. Facing the arrows ashore. Began to launch an attack on the Don army in formation.

The arrows of the Tang army could not penetrate the heavy armor of the Mo Dao Army, and most of the soldiers encountered the Mo Dao Army of the Sui Army for the first time. This fearless soldier caused them to retreat in terror, and there was a commotion in the camp.

The main general, Wang Huaiwen, was a Sui general, and he knew that this was a heavy infantry with a clap blade in his hand, and in the Wei and Jin dynasties, this kind of heavy infantry was used to deal with the northern nomads, but the slap blade in the hands of the Sui army was thinner and longer.

"General, I'm afraid it's not good to send out the cavalry!" A partial general also felt bad, and he hurriedly reminded Wang Huaiwen.

Wang Huaiwen stared for a long time, and resolutely ordered: "Cavalry attack!" ”

Two thousand cavalry suddenly launched and rushed towards the Sui heavy infantry who had just come ashore, trying to knock this heavy infantry down the Yellow River with speed and impact.

But the end was a heavy blow to the Tang cavalry, the heavy infantry resisted the impact of the Tang cavalry, the row of knives and slashes, under the light of the knife, invincible, five hundred heavy infantry advanced like a wall, killing the corpses of the cavalry and horses, and the blood flowed like a river.

"General, withdraw!"

All the generals shouted anxiously, Wang Huaiwen finally took a deep look at the five hundred heavy armored infantry, his eyes showed a look of disappointment, he could not catch a single heavy infantry, seeing that the two thousand cavalry had suffered heavy losses, and the momentum of rout, and more and more Sui soldiers with huge shields and spears began to land.

As a last resort, Wang Huaiwen had no choice but to order: "The whole army retreats!" ”

More than a thousand cavalry and less than 3,000 crossbowmen quickly withdrew from the battlefield.

Because there was no main force of the Tang army to participate in the battle, this doomed the battle of Mengjindu was only a small battle of harassment, and its role could only be to delay the landing time of the Sui army, but could not prevent the main force of the Sui army from landing.

The 50,000 troops of the Sui Dynasty began to land in a mighty manner, and at this time, the three-pillar beacon fire was ignited on the beacon tower a mile away, and the information on the appearance of the main force of the Sui army was quickly transmitted to the Tang army camp in Luoyang......

Early the next morning, Wang Huaiwen led the retreating Tang army back to the Luoyang camp, the Tang army did not attack Luoyang in the past two days, and began to prepare to pull out the camp and retreat westward, when Li Shimin heard the news that Wang Shichong removed the emperor's name, he immediately realized that the main force of the Sui army was going to send troops, and removing the emperor's name must be a condition issued by Yang Yuanqing.

With the Sui army dispatching troops, the battle situation began to become delicate, the situation that was originally Tang Qiang and Zheng weak was suddenly reversed, the situation began to be unfavorable for the Tang army, Xu Shiji led 20,000 Sui troops on the West Road in the area of Hangu Pass, and Yang Yuanqing's tens of thousands of main forces came from Yanshi County, left and right, the Tang army lacked strategic depth, and this battle was undoubtedly defeated.

In the big tent, Li Shimin and dozens of generals listened to Wang Huaiwen tell the details of the battle of Mengjin, especially the Modao heavy infantry, and everyone listened attentively.

"The opposing team's heavy infantry is only five hundred, but the combat effectiveness is quite strong, their blades are thinner and longer than the ones I know, and they seem to be sharper, five hundred people withstood the impact of the cavalry, fought collectively, and killed two thousand cavalrymen with heavy casualties."

At this moment, a soldier walked into the tent with an old-fashioned clapper blade in his hand, which was actually a single-pointed, two-edged knife.

Wang Huaiwen took the thirty-pound blade and continued to everyone: "The blade of the Sui Army is three feet longer than this one, the blade is two feet long, it must be thin and light, and the blade is also thin, but it feels very hard and sharp, I haven't seen the real thing, but I feel that creating a Sui Army blade requires good iron and craftsman skills, and our craftsmen may not be able to build it." ”

At this time, another personal soldier came in, and he also held a clapper blade in his hand, but the slapper blade just now was thinner and longer, which was completely consistent with Wang Huaiwen's description, and many of the generals exclaimed.

Wang Huaiwen's eyes widened, he slowly took the long slapping blade, waved two knives, and excitedly said to the generals: "That's it, it's exactly the same as Sui Jun's slapping blade, it's really a good knife!" ”

He suddenly wondered where this blade came from, and he asked Li Shimin with some puzzlement, "Is this captured by His Highness from the Sui army?" ”

Li Shimin took the clapper blade and shook his head and said, "This clapper blade was actually created by the swordsmith of our ordnance supervisor last month. ”

There was an exclamation in the big tent, their own craftsmen could actually build it, Wang Huaiwen was extremely excited, "Your Highness, then can we also form a heavy infantry like the Sui army?" ”

Li Shimin smiled bitterly and sighed slightly: "I also hope so, but it is not realistic, this knife is not called a slapper blade to be precise, but called a Mo knife, whether it is iron or forging technology has extremely high requirements, as early as more than a year ago, we began to pay attention to this Sui army's heavy armor Mo knife army, I specially gathered the best knife craftsmen in Chang'an Military Weapons Prison." ”

Speaking of this, Li Shimin was a little deflated, he sighed and said: "It's a pity that we don't have a sample knife, let alone forging technology, the Sui Dynasty kept it a very strict secret, Tang Feng tried his best to get nothing, our intelligence is the same as General Wang, we only know that it is extremely long and thin, extremely hard and sharp, and we don't know anything else, so it took our swordsmiths more than a year to finally create such a Mo knife, and their heavy armor, we also made it, but the problem is that we don't have the time and so many excellent craftsmen, To build a 3,000-strong heavy armor Mo sword, it will take at least two years to exhaust the strength of the Tang Dynasty before it can succeed. ”

King Qin's words made everyone's hearts a little heavy, and Wei Chigong asked curiously: "Your Highness, is the heavy armor Mo Sword Army of the Sui Army invincible, and there is no way to restrain it?" ”

"Nope! The Sui army's heavy armor Mo sword army also has natural enemies, when attacking Dou Jiande's camp, Dou Jiande's army used bed crossbows, I heard that hundreds of heavy armor Mo sword soldiers were shot, maybe a bit exaggerated, but the bed crossbow iron arrows can indeed penetrate the heavy armor of heavy armor Mo knife soldiers, which allowed me to find a way to deal with heavy infantry soldiers. ”

Speaking of this, Li Shimin smiled slightly, "In fact, there are many ways, such as we dig a big pit, they will not come out if they fall, and then burn them with fire oil, they will die the same, everything in the world always falls one thing to another, there is nothing invincible in the world, and the Sui army cannot rely on a heavy infantry to sweep the world, as long as we are vigilant, we can minimize the casualties and losses." ”

The atmosphere in the military tent became warm again, and at this time, a soldier rushed in to report: "Your Highness, there is urgent information in Hongnong County!" ”

Li Shimin took the information and read it, his face became solemn, and he said slowly to the generals: "Xu Shiji led the army into Hongnong County to cut off our back road." ”

Li Shimin sighed, and now, he can't help but withdraw his troops, he immediately ordered: "Pass my order, the army will withdraw to Hongnong County!" ”……

Due to Yang Yuanqing's army crossing the river, the Tang army realized that it could not take Luoyang, in order not to be cut off by the Sui army, Li Shimin was forced to order the withdrawal of the army, 70,000 Tang Dynasty troops withdrew in the direction of Hongnong County, and the battlefield was withdrawn to Hongnong County, and the Tang army's withdrawal from Luoyang did not mean that they gave up the Central Plains, and keeping the occupation of Hongnong County became the top priority of the Tang army, and a major war between Yang Yuanqing and Li Shimin was about to kick off in Hongnong County
