This army of the Jin Kingdom, which had been given high hopes, was still using the Morris phalanx, which had long been eliminated by Chen Xian, and the proportion of musket equipment was only 50 percent, and half of the 50 percent musketeers were still using arquebuses.

Opposite them? The proportion of musket equipment in the Mongol Han army has been as high as about 70%, and all of them are flintlock muskets.

In terms of artillery, among the hundreds of cannons brought by the Mongols, there were more than 100 cannons of ten catties, while the largest cannon of the Jin people was only five catties.

In terms of cavalry, the iron cavalry and cavalry of the Jin people were completely unable to adapt to the current battlefield, while the Cossack-style Han cavalry among the Mongols was completely designed for this kind of battlefield.

The outcome of the battle was already predestined before it even began.

The 100,000-strong army of the Jin State was completely annihilated by the Mongols in the fortress belt.

The Jin people, who had lost their ability to fight in the field, could only watch as the Mongols besieged their fortresses one after another, and finally successfully passed through the fortress defense belt they had painstakingly managed!

However, even if they passed through the fortress belt in the east of Tongguan, the Mongols could not sit back and relax, and there was still a difficulty in front of them, that is, the fortress defense group built by the Jin people in Luoyang, relying on the northern mountains and the eastern hilly area.

Since Genghis Khan's eastward crusade, the Jin people have retreated in Shaanxi, Henan, and Anhui, and in addition to waging several stupid wars to recover losses from the Song people, another major thing they have done is to operate two fortress defense rings in Luoyang and Nanjing (Kaifeng).

These two defensive rings, of course, are the larger defensive circles of Nanjing (Kaifeng), the capital of the Jin Kingdom, with more and larger fortresses.

However, outside Kaifeng City, the terrain is not suitable for defense.

Although the scale and quality of the Luoyang defensive circle are not as good as those of the Nanjing defensive circle, the terrain of this place is more complex, which is conducive to defense.

In the history of China, many wars have been carried out around the defense of Luoyang, which shows the excellent defensive posture here.

The Luoyang defense circle operated by the Jin people has two centers, one is Luoyang City, and the other is the Beibi Mountain Daying.

The two defensive cores are horns and support each other.

In particular, the Beibi Mountain Battalion, relying on the terrain and the condescending artillery and musket defense, was more easy to defend and difficult to attack than in the cold weapon era.

And if you don't conquer the camp of Beibi Mountain, you can't attack Luoyang City, which is protected by dense fortresses.

If there was no fortress that was a sinful thing, relying on the terrain of Luoyang alone, it would be impossible for the Jin people to stop the Mongols.

However, with the fortress that was almost impossible to conquer in this era, Luoyang's easy to defend and difficult to attack situation was magnified by the fortress.

The people of the Jin Kingdom learned from Chen Xian's practice and concentrated all the people around Luoyang City in the fortress, and used the fortress to control the surrounding arable land, so that the Mongols could not even get food near Luoyang.

On the plain east of Luoyang, there are also simple fortresses, maintaining the traffic between Luoyang and the eastern plain of Henan.

Wokotai almost turned white outside Luoyang City.

Luoyang is a place, you can't go around, there are 100,000 troops hidden there, you want to go around here, do you want a supply line?

If you only take the Mongol cavalry back, you can rely on burning, killing and looting to maintain supplies, anyway, the Mongols have always done this, but with more than 100,000 Han infantry, he can't do this.

Just when Wokotai was worried outside Luoyang City, Chen Xian's army finally felt relieved after building forts on the south bank of the Yellow River near Kaifeng and Xuzhou for two months, and finally drove the army out of the fortress on the bank of the Yellow River and marched towards Kaifeng and Xuzhou City.

In these years, the people of Jin focused on the defense of Luoyang and Kaifeng City.

It's not that they don't pay attention to the defense of the East China Sea in the direction of Xuzhou, but in this direction, in addition to the Yellow River, one horse and one Pingchuan, once the enemy crosses the Yellow River, it will be impossible to defend at all, and it is meaningless to simply operate one or two cities.

Jin Guoren want to operate, but they can't afford it.

According to the battle plan, Li Shi led his Western Route Army to attack Kaifeng City, set up a large camp in the east of Kaifeng City, and then selected a few fortresses on the front and began to build walls and simple fortresses on its periphery.

In recent years, the upper echelons of the Jin State have built quite dense fortresses outside Kaifeng City in order to be safe, and even the powerful Chen Army has no choice but to use stupid methods to besiege them one by one.

On the other side, Yang Xiaoyi easily captured Xuzhou City, which was not protected by a fortress.

Next, he took Xuzhou City as his base camp, divided his troops into several routes, stationed in Xuzhou all the way, and swept along the south bank of the Yellow River along the prefectures and counties, seized and established strongholds, and went all the way south, sweeping the prefectures and counties along the way, mainly led by Yang Xiaoyi himself, and went straight to Defu.

Two infantry divisions remained in Xuzhou, and they swept up and down the Yellow River in two routes, occupying dozens of strongholds on the south bank of the Yellow River in just a few months.

Chen Xian organized a large number of engineering teams on the north bank, relying on the strongholds occupied by the Xuzhou army on the south bank of the Yellow River, erected dozens of pontoon bridges, and transported a large number of materials, a large number of engineering personnel, a large number of officials, and a large number of militia to the south bank of the Yellow River.

With the army opening the way, the reserve officers and militiamen who crossed the river began to take control of the forts in the countryside.

At one point, Chen Xian's bureaucratic government, after years of suppression, began to work at full speed.

Despite years of repression, this time the bureaucratic government was re-established and functioned in the occupied territories, and instead of degrading, it worked more smoothly.

The reason is very simple, because at this time, the East China Sea Kingdom had a group of officials with the highest professional quality in this era, and a large number of various professionals trained by the system, and it was actually these grassroots personnel who ensured the efficiency of the bureaucratic system, not middle and high-level government officials.

The wartime bureaucracy of the East China Sea State quickly took control of the six or seven hundred miles long stretch of the south bank of the Yellow River from Guide to Huaisi.

In this area, all the county towns and state towns were occupied, and all the Haoqiang fortresses were controlled.

Henan Haoqiang, who had long heard of Chen Xian's brutal methods, fled one after another, and those who were able fled to the west, and those who were not able ran to the county and state, and everyone knew that as long as the landlord Haoqiang gave up the land and ran into the city, Chen Xian would open the net.

But there is a group of people, even if they run into the establishment, Chen Jun will not let go, that is the Jurchens!

Whether it is in the countryside or in the city, the Jurchens are screened out.

This time, Chen Xian did not order the expulsion of the Jurchens, who were screened out, detained, and finally all escorted back to the north bank of the Yellow River, and finally concentrated in concentration camps outside Qingdao.

In the end, in the desperate cry of the Jurchens, they were taken as a family unit, put on large ships, left the port in the wind, and sailed south.
