At the beginning of February of the second year of Longxing, Xingren Mansion sent 20,000 troops north to Lanzhou, a fierce battle for a day, the Jin army was defeated and took two counties, the Jin army held on to Lanzhou, and the Song army immediately went eastward, passing through Fan County and Yanggu County, and attacked Bozhou directly.

With the help of the Shandong Righteous Army, the Northern Expeditionary Army of Xingrenfu led by Xue Wang lasted one day and broke through Bozhou City.

The Northern Expeditionary Army of Xingrenfu and the Shandong Righteous Army were connected north of Jishui.

The news was transmitted back to Lin'an, and the haze of the new defeat of the Northern Expeditionary Army in Qixian County was swept away, and the position of the main battle faction in the court and China was slightly stabilized.

On March 16, Lin'an ordered Yang Congyi to serve as the envoy of Jingdong, Jingbei, Shandong, and Hebei, and the commander of the Right Army of the Northern Expedition, and the army moved to Jeju.

On the fifth day of the fifth month of May, the imperial court simultaneously issued an order to Yang Congyi, the right army of the Northern Expedition, Li Xianzhong of the Chinese army, and Wu Gong of the left army, to advance on the whole line, go all out on the Northern Expedition, and recover the old land of the Central Plains.

On May 25, Li Xianzhong personally led an army of 100,000 troops, which was the first to attack from Guide Province, breaking through the Jin army's Qixian defense camp in one fell swoop, and the remnants of the Jin army withdrew to Bianjing, and then turned to attack Tongxu, fought fiercely for two days, defeated the Tongxu Jin army, and destroyed the county seat of Tongxu.

On May 29, Wu Gong sent 50,000 troops from Xuzhou to attack Weishi County, fierce battle for a day, the city was not broken, the Jin army did not retreat, after holding each other for many days, Li Xianzhong sent troops to reinforce, the two armies broke the city together, killing more than 30,000 enemies.

By the seventh day of the first month of June, the three Gongwei battalions south of Bianjing, Weishi, Tongxu, and Qixian were all destroyed, and the defenders in the south and east of Bianjing were all shrunk to within 10 miles around Bianjing, further concentrating their forces.

On the tenth day of the first month of June, Li Xianzhong ordered the first part of the Xingren Mansion garrison to enter Lanyang to compress the space for the Jin army's activities.

Beginning on June 15, the left army of the Song army's Northern Expedition abandoned Xuzhou, and the Chinese army of the Northern Expedition abandoned Guidefu, mobilized all troops, a total of 150,000 troops, and went north to confront the Jin army in Xiangfu County.

On June 21, the Jin army gathered 200,000 troops and fought with the Song army in Xiangfu.

The two sides fought fiercely for a day, the Jin army was defeated and fled back to Bianjing, and the Song army also suffered heavy casualties.

On June 23, Li Xianzhong set up the eastern camp of the Northern Expeditionary Army 20 miles southeast of Bianjing, and on the same day, Wu Gong set up the western camp of the Northern Expedition Army 20 miles southwest of Bianjing, with the east and west battalions 30 miles apart, blocking the Jin army in Bianjing City, so that it could not go out of the city at will, let alone go south to invade the people in various cities.

When the news of the Northern Expeditionary Army coming to Linbian Capital City came back to Lin'an, Emperor Zhao Yan and the ministers of the main battle faction were all overjoyed, and even the people of Lin'an began to talk about the Northern Expedition.

In nearly forty years, this was the first time that the Song army had been so close to Bianjing.

The reputation of Li Xianzhong and Wu Gong was unique in the Great Song Dynasty army for a while, and the scenery was infinite.

Seeing that the Jin army was defeated again and again, and the Northern Expeditionary army was under Bianjing, many lords and ministers changed their positions and began to support the Northern Expedition.

Due to the great change in the situation in the court, the east and west battalions outside Bianjing City were ordered not to attack rashly, let alone destroy Bianjing City.

Li Xianzhong and Wu Gong took this opportunity to stand still, rest and recuperate, and only wait for the time to be ripe, and then capture Bianjing City in one fell swoop.

Just when Li and Wu joined forces to advance towards Bianjing, Yang Congyi, who was in Jeju, was not idle.

Half a month after moving to Jeju, Yang Congyi sent his subordinate officers to send a letter of appeasement to the Shandong Righteous Army.

Half a month later, Shen Fu, the leader of the Shandong Righteous Army, brought the entire Shandong household registration register to vote, expressing his willingness to join.

At the beginning of May, the news of Yang Congyi's success in recruiting the Shandong Righteous Army was sent back to Lin'an, and Da **Bai got the entire Shandong East Road, and Zhao Yan was in high spirits for a while.

When I heard that Shen Fu, the leader of the Shandong Righteous Army, was a scholar, he had studied in Jiangnan in his early years, and then did business, and when the Jin people invaded the south, he scattered all his wealth, recruited the rebels, rose up against the Jin people, and read his loyalty.

The officials of the counties in Shandong Prefecture contained in the roster are all corrected and compiled by the Ministry of Officials, and they are all officials of the Great Song Dynasty.

At the same time, the edict decreed that all prefectures and governments on Shandong East Road would reduce or exempt taxes for three years and not levy forced labor.

At the end of May, the edict was transmitted to Yidu Mansion in Shandong, and Shen Jin accepted the canonization of the imperial court as Shen Fu, and the two prefectures of Shandong were officially attached to the Great Song Dynasty.

On the eighth day of June, the Shandong Righteous Army was reorganized into the Eastern Route Army of the Northern Expeditionary Army of the Great Song Dynasty, with Yao Chang as the commander of the Left Army and Luo Cong as the commander of the Right Army.

On June 23, the two armies combined with 100,000 troops and easily captured Texas.

On the first day of the seventh month, the two armies jointly attacked Beizhou, killing 5,000 enemies and capturing 20,000.

On the sixth day of the seventh month, the Northern Expedition Right Army and the Eastern Route Army gathered 150,000 troops, besieged the Daimyo's Mansion, and fought fiercely for three days.

After taking the Daimyo's Mansion, 100,000 troops were stationed and rested for ten days, and then divided their troops to besiege and kill the Jin army.

After two months of strangulation, within a radius of 100 miles, there was no trace of the Jin army.

At the same time, a detachment of the Eastern Route Army of the Northern Expedition took advantage of the chaos to quietly enter the Taihang Mountains from Handan County to the west.

After taking the Daimyo's Mansion, the Northern Expeditionary Army did not continue to attack the north, but instead began to manage the cities and lands it had already occupied.

At this time, the entire Jin State had been cut into two halves in the north and south by the Northern Expeditionary Army led by Yang Congyi, and the connection between the Zhending Mansion and the national capital Bianjing was not smooth, and it was even more impossible to transport grain and grass materials between the two places.

Wan Yanliang's strategic plan was completely disrupted by Yang Congyi's troops from the east to the Daimyo's Mansion, and there was a big problem in the transfer of troops from the north and south, and even their desire to leave Bianjing and return to Zhending Mansion became a problem, because the Song army stationed 100,000 troops in the Daimyo's Mansion.

However, fortunately, after the Song army occupied the Daimyo's Mansion, it did not go south to encircle Bianjing, and a large area of land south of the Daimyo's Mansion and north of Bianjing was still in the hands of Wanyan Liang.

After entering August, the weather became hotter and hotter, and the Northern Expeditionary Army and the Jin Army entered a full-scale confrontation, and the two sides no longer took the initiative to attack.

At the beginning of September, 100 huge sea ships entered Laizhou Bay, and more than 600,000 quintals of grain were sent to Yidu Prefecture.

This huge amount of grain was immediately sent to Jinan Mansion in batches, and then to the Daimyo Mansion.

Transportation problem, Shen Jin has been solved over the years, he created a kind of four-wheel steering carriage, according to the load difference, the carriage chassis has wooden, iron, wooden four-wheeled carriage, a vehicle weight can reach 1,000 catties, and the iron structure carriage wheels are more, the load capacity can reach up to 5,000 catties, but unfortunately there are no four high-headed horses together can not pull at all, and can not last, can not walk a few miles, the horse will be tired of flirting hooves, so the load tool at present, or can only be a four-wheeled carriage with a load of 1,000 catties.

In the plain terrain, the road is flat, if there is a cart of two horses, there are extra horses to change, and the load-bearing carriage travels hundreds of miles a day, which is not a problem at all.

Therefore, the grain unloaded from Laizhou Bay was quickly transported to a huge granary in Yidu Province, and then distributed to Jinan Province through a convoy, and then transferred to the Daimyo's Mansion.

Shen Jin has not been idle in Yidu Mansion in recent years, although he rarely deals with government affairs, but he spends a lot of time on researching and manufacturing all kinds of tools.

Although the power plant developed for sea ships cannot drive 2,000 large sea ships, if it is used in iron carriages, the speed of the carriage will not be slower than that of wooden carriages when fully loaded, but the problem is that if the power plant used for sea ships is used in horse-drawn carriages, then such carriages will be many times larger than existing carriages, and it is very complicated to use, and it does not seem feasible at present.

In addition, the development of assault rifle and cement is progressing quite smoothly, the range of assault rifle has been able to reach more than 200 steps, and the accuracy can also be comparable to crossbow arrows, but unfortunately, the iron assault rifle can not last, and it must burst when excited about ten times, intersecting with expensive manufacturing costs and complex and cumbersome manufacturing processes, and the assault rifle does not have the significance of large-scale manufacturing, and it is better to make more bows and crossbows.

The most useful is cement, the construction and reinforcement of the city defense of Yidu Mansion and Jinan Prefecture are using a large amount of cement, which is cheaper than glutinous rice porridge, and the key is that the firing material is easy to take.

The thickness of the city wall of Jinan Mansion and the city wall of Yidu Mansion reinforced by cement construction is up to two zhang, up to more than three zhang, and the reinforcement construction process took only three or four months, which was unimaginable in the past.

There is also the development of glass lenses, which have also made great progress, and the clarity and smoothness are many times higher before they intersect.

When Shen Jin met with Yang Congyi in Jeju in April, he talked about the "construction of the institute", and Yang Congyi gave him a lot of research directions and suggestions, and now he has guided the craftsmen of the "construction institute" to start the development.

After more contact with the army, Shen Jin felt more and more that Yang Congyi's original preparation for the establishment of the "construction institute" was not for a better recovery, and the ultimate goal was probably to increase the combat power of the army.

After more than two years in Shandong, Shen Jin also understood that the purpose of their establishment of the Huiyi base on Qindao at the beginning was not actually to return to Yi.

After staying in Shandong for a long time, he gradually realized the decisive role of occupying Shandong in the Northern Expedition, the coastal area is remote, and the land is not as flat and fertile as Jianghuai, Bianjing, and Damingfu, and it is not a place where soldiers must fight, and the terrain is also very favorable.

Today's Shandong, after two years of tax-free recuperation, the agricultural production that was destroyed earlier has been restored, the people live in peace, the political situation is stable, business travel has also resumed quickly, as long as there is money, you can buy a lot of things.

A stable Shandong is of extraordinary significance to the Northern Expedition.
