When the 600-mile expedited military intelligence from Liaodong arrived in Beijing, Huang Taiji had already led his army across the Yalu River and set foot on the territory of the Xian Empire.

When the Jin army assembled by the Yalu River, the Ming army and the Xian army stationed in the Yalu River area both discovered that the Ming army's response was to be on strict guard while sending people to report to their superiors, but the Xian army was still as usual, lazy and lazy, not at all vigilant.

It's no wonder that the Xian army is careless, now it's almost summer, there is a lot of rain, the natural barrier of the Yalu River is turbulent, the water level is rising, and the Jin army has not been cut down trees and built ships, and moreover, the Xian Empire has not invaded by foreign enemies for ten years, and it is so calm that people have the illusion of world harmony, and they take it for granted that the Jin army is going to fight the Ming army on the other side of the river.

If the Jin army wants to cross the river, it can only build ships, and the logistics auxiliary soldiers have long cut down trees and built ships, and the movement of building large ships is too big, it must be discovered by the Xian army, and it is time-consuming and labor-intensive, so all the boats are built, and there are quite four or five people on board, or two people and a horse, all of which are hidden in the woods and can be carried down the river at any time.

In order to paralyze the Xian army, the Jin army also created a momentum of attacking the Ming army's border fort fortress, which made the Xian army believe more and more that it was a war between the Ming and Jin countries, and it had nothing to do with them, they just watched the lively melon-eating masses.

When the sky was about to brighten, the well-rested, well-fed warriors of the Jin Army carried small boats out of the woods, rushed to the Yalu River, put the small boats into the river, and then boarded the boats, rowed hard to the opposite bank, and at the same time lowered the long ropes on the boat.

Because it was dark, the river was turbulent, more than a dozen small boats overturned, drowning dozens of people, and after the remaining dozens of small boats arrived on the opposite bank, the warriors who landed first fixed the long rope on the river bank, and the soldiers of the boatman only needed to pull the long rope to drive the small boat to travel, which was not only safe, but also accelerated the carrying speed.

When they found that a small number of Jin troops had crossed the river, they were so frightened that they screamed desperately, some ran to the border city to report, and some sounded the gong to call the police, alarming the fresh troops stationed in the border city.

However, the fresh army in the border city waited for nearly an hour before gathering more than 2,000 soldiers to pour out of the city and kill the river.

At this time, the Jin army that had smuggled into the landing was only more than 500 horsemen, and they urged their mounts to kill the more than 2,000 fresh troops who rushed in.

"Formation, hurry up and ......" shouted the officer who led the team, ordering his soldiers to form a formation to resist.

The reaction and command of the officers of the Xian army are still correct, knowing that the cavalry is born to be the nemesis of the infantry in the field, and only by forming a formation and setting up a large array of spears to resist can they save their lives, but the soldiers under them are really unreliable, they are all five scum of the war, and they were frightened by the charging Jin army with a wave of cavalry bows, and they were frightened when they fell a dozen people, and the rolling iron cavalry in front of them crushed them, and they screamed in fright, threw away the weapons in their hands, turned around and ran, someone took the lead, and someone followed, and the team of more than 2,000 people was like an ant colony that exploded the nest, and it exploded with a bang.

"Drive them into town!"

The Jin army of more than 500 horsemen chased after the tail, and the general Azig who led the team to rush and kill shouted loudly, the fleeing fresh soldiers would definitely not be able to outrun the war horses that charged at full speed, and if they really wanted to cut and kill, they could be wiped out casually, but their goal was the border city in front of them, intentionally or unintentionally slowing down the speed of the galloping horses, driving these routs to flee into the city, and rushing in to seize the city.

"Close the gates, close the gates."

The officer commanding at the head of the city was dumbfounded, and he farted a special fart, and the smell was defeated before it was finished? He was stunned for a long time before he reacted, shivered violently, roared loudly, and ordered the soldiers to close the city gates.

However, his orders were not carried out by the soldiers, and it was their brothers and brothers who were hunted down outside the city, how could they watch them being killed by the enemy?

Although the Xian army fought five scum, it must be admitted that in order to save their lives, the speed of their escape was still very fast, people were forced to a desperate situation, their potential was stimulated, and those who ran fast had rushed into the city gate, but most of them were crowded on the city bridge, and some unlucky people were squeezed and fell into the moat.

"Kill!"

The Jin army, which was chasing behind, accelerated the speed of the charge, slashing towards the city gate like a whirlwind, waving machetes to cut down the fresh soldiers in the way, and the horses charging at full speed knocked people away or trampled down, and in the blink of an eye, it was like a flood without embankment, rumbling into the city.

The fresh soldiers in the city were frightened, scattered and fled, and some dared to resist, but they were all chopped up, the Jin army only captured this border fortress with more than 500 horsemen, and the 100,000 troops led by Huang Taiji were able to calmly cross the river and land into the city with swagger.

In order to speed up the speed of the army crossing the river, the Jin army swept around in several ways, grabbed a lot of fishing boats to carry men and horses, and the small boats built day and night did speed up the speed of crossing the river, but because of the small boats and small carrying capacity, it took the 100,000 troops a full five days to cross the Yalu River.

During this period, the news of the Jin army's cross-river invasion has spread throughout the entire Xian Empire, the government and the opposition are shaken, the people are panicked, the generals of each city are desperately recruiting young and strong, expanding their own strength, the king of the Xian Empire Li sent several groups of envoys to the Ming Dynasty for help.

Li Xin, as the commander of the expeditionary force, unceremoniously scavenged more than 40 Franco cannons that had just been produced in the Liaodong Arsenal and stored in the warehouse, a large number of flowering shells, and the bitter acid thunder that had just been mass-produced, which made the senior generals in Liaodong look greedy.

They have already seen the power of picric acid explosives, which is much more ruthless than the thunder of today's equipment, once it explodes, the fire cannot be extinguished at all, the more the fire is beaten, the more it spreads, it can burn on the surface of the water, it is indeed a big killer weapon to attack fortifications and deal with cavalry, however, the battle of the Ningjin defense line has ended, and there is no need for this thing for the time being, so I can only watch Li Xin scrape all these treasures.

The distress messenger sent by King Li learned that the Ming Dynasty was already assembling an army and preparing to send troops to the rescue, and he was so moved that he ran back to report the good news to the Lord of Li, and the Xian Empire was happy, but before the Ming reinforcements arrived, they had to support the attack of the Jin army.

Li Guoyu gave an order, the whole country was mobilized, and a large number of young and strong people were forcibly conscripted, and the strength of the royal city of Hanyang instantly soared to more than 400,000, and the strength of various cities and provinces was also soaring.

In the original history, the people of the Xian Empire are still inclined to the Ming Dynasty, the Ming Dynasty pursues Confucianism, many people are stupid and foolish, they want to save face, pay tribute every year, and offer a few worthless dry goods, they can fool a lot of money and grain, etc., and the people of the Jin Kingdom are cruel and do all kinds of evil, after the defeat and surrender of the Xian Empire, not only was robbed of a large number of food and other resources, but also took 500,000 Xian people as prisoners and sent back to the country as slaves.

When the king was besieged, all the reinforcements were Qinwang, but they were all defeated by the Jin army, and the people of the Xian Empire resisted while waiting for the reinforcements of the Ming Dynasty, but at that time, the Ming Dynasty was already too busy to take care of itself, how could they have the spare strength to send troops to rescue.

Although the Xian army fought five scum, its resistance was quite tenacious, and it successively killed the Jin army generals Yangguli, Zuoling Gushan, Dalan, Xiao Cavalry School Monk Xi, Yun Cavalry Captain Ehai, Counselor Temur, Zuo Ling Bi Yada, Ah Niu, Du Min, etc., but they still couldn't reverse the defeat.

Different from the original history, Zhu Jian, the imposter of heaven, was very determined to send an elite expeditionary force to rescue the Xian Empire, however, he was not stupid and foolish, on the contrary, wishful thinking crackled, and the rescue of the Ming Dynasty was not free, but paid and conditional.
