Zong Bi's situation in Henan is completely different from Zong Han's situation in the clouds.

The territory of the Jurchens in Henan is larger than that of Yunzhong, which is the hinterland of the Central Plains, where the old Song Jingshi is located, although it has been damaged several times, but the economic situation is still not comparable to the northern border counties like Yunzhong. However, Zong Bi also faced another serious problem, that is, the place he ruled was completely Han territory, and the economic form and social environment were very different from the Jurchen people formed in the northeast.

During this time, Zong Bi was able to maintain his rule here, thanks to the fact that one of the two major forces in the north and south was unable to go south, and the other had no intention of going north. The people in Henan who have the most sense of resistance, national integrity and organizational ability went north and south in large numbers during the Jingkang period, or belonged to Cao Guangbi and the loyal army to fight in the two rivers, or immigrated to Jiangdong from Zhao Gou, and those who stayed in the local area at the moment either went with the flow, or went against the grain, and even helped the Han army to abuse and enjoy the Hu slaves, plus the Han army did not enter this area for a long time, and Zhao Gou intended to use Zong Bi's forces as a buffer between the Han and Song dynasties, and the internal and external situations were coordinated. Although there were anti-Jurchen incidents in Henan during the reign of Zong Bi, all of them failed one by one due to the lack of organization and external response.

After the Jin Army's Eastern Route Army moved south, although it showed a relatively strong aggression in the early stage, as time went by, the Eastern Route Army quickly showed a tendency to localize from top to bottom. In terms of political system, Zongbi had to use a large number of Han officials, because the Jurchen rulers could not create a more advanced model than the original ruling system of Jiuji, so they could only rely on Han Chinese officials to implement Han rule. Not only Wenzhi is like this, but even the Jurchens who migrated south were gradually influenced by the locals in terms of folklore - although the Jurchens were strong, as soon as they arrived in Jiugi in the Central Plains, they were like a basin of fresh water poured into a pot of salty water, and they became tasteless and tasteless.

If the biggest problem facing Zonghan Group in the cloud is financial problems, then the biggest problem facing Zongbi Group in Henan is cultural problems. If this development continues, it is only a matter of time before the Zongbi group is assimilated into a regional regime, and once the Jurchens completely lose the edge of the Northern Clan, they can only wait for the Han Dynasty or Zhao Song to take over.

The leaders of the upper echelons of the Zongbi group all saw this crisis, so although they were not as embarrassed financially as the Zonghan group, they were also very eager to take the initiative. And this time to the north, the main force of the Henan Jin army was no longer cavalry, but infantry - even more than half of the elite. The composition of the army, the number of the Han army also far exceeded that of the Hu department. This is a very dangerous sign, but Zong Bi himself can't help it. Fortunately, these Han troops also showed strong combat effectiveness, and there was no mutiny for the time being - after all, Zongbi could still guarantee their food, so they were also quite loyal to their foreign masters.

The war began in full swing after Zong Bi received a verbal promise from the Southern Song court, and Zong Bi, who had no way out, after receiving Zhao Gou's assurance, launched several large armies to threaten the Han army's defense lines in Luoyang, Hedong and Hebei - Shandong did not attack because of a secret agreement with Zhao Gou, which was intended to be left to the Song army.

At this time, Li Yanxian had been transferred out of Luoyang and went to the northwest to take up his post, and Luoyang's defender became Wang Yan, who relied on Bishui and Songshan to resist Zong Bi's attack, and did not fall behind at all. Xu Wen was stationed in Hanoi to prevent Zong Bi from crossing the river and copying Hedong. On the Hebei side, the most important of several directions, Cao Guangbi sat in the Daimyo's Mansion and confronted Zong Bi's main force head-on.

At the beginning of the war, Cao Guangbi, who was under excessive political pressure, seemed to be a bit blamed in the layout, in order to protect the achievements of Hebei's economic reconstruction in the past year, Cao Guangbi attached importance to the border states and counties almost everywhere, but the result of the attention everywhere became an average force, when the Jin army covered up in a big way, the troop layout in some areas seemed wasteful, and some areas in the face of the Jin army's concentrated forces appeared weak links, Cao Guangbi's mistake led to a Jin army invasion to the south of Cangzhou, It had a considerable impact on the stability of the political situation in Tanggu, and even affected the diplomatic situation of the Han Dynasty.

Fortunately, Zong Bi did not expect this unexpected victory, so he was unable to add troops to this gap in the Han army in time, and Cao Guangbi hurriedly dispatched the reserve army of the Daimyo's Mansion to make up for this loophole.

This incident made Cao Guangbi realize that the Zong Bi army at this moment, whether in terms of the combat power of the troops or the strategic thinking of the generals, was very different from the Zong Bi army when he first went to Henan. In view of the current situation, he readjusted the layout of the Yellow River front. However, no matter how good a general is, it is inevitable that flaws will be exposed when making such a large-scale adjustment, and Cao Guangbi is no exception. And Zong Bi keenly captured this flaw of Cao Guangbi, and when the roads of the Han army were not properly arranged, he led 30,000 infantry and 5,000 cavalry to the city of the Daimyo's mansion.

The Daimyo Mansion is located between the two major rivers of the Yellow River, and the Yongji Canal in the northern section of the Grand Canal also passes through here. At that time, the regular army of the Daimyo Mansion was only 8,000 people, and in the face of the sudden attack of the Jin army, the soldiers and civilians in the city were all panicked. The hub of the Yellow River defense line was located here, and the base camp of the Yellow River Military Region to guard against Zong Bi and Zhao Gou was also here. They knew that this battle would not only affect the survival of the Daimyo's Mansion, but also the success or failure of the entire Yellow River Front, and the success or failure of the Yellow River Front would be related to the survival of the entire Han Dynasty! If it was just the loss of one city and one place, they could still muster up the courage to sacrifice their lives for the country, but they really couldn't afford to lose this battle!

At this time, Cao Guangbi once again showed his tenacity and decisiveness, he temporarily put down his heavy responsibility as a marshal, became a general of a force of 8,000 people and a defender of a city, returned to the city, returned to the battlefield, and specifically commanded the defense work of the army and people in the city.

"It doesn't matter, I already expected Zong Bi to come, and I have already passed down the order. After three days, the army of Shandong will cut off his back route, five days later, the soldiers and horses of Xiangzhou will reach the flank that threatens him, within seven days the reserves of Handan will arrive, and within ten days Zongbi will be shut down by us and annihilated under the city of the Daimyo's Mansion. ”

The staff officers of the Yellow River Front were both excited and amazed when they heard this, and they were so impressed by the ability of Cao Guangbi's uncertain prophet that they threw themselves on the ground! No one knows that this is a lie! Zong Bi's appearance was really unexpected, in fact, Cao Guangbi didn't even send a letter asking for help in time. However, Cao Guangbi's prestige was enough to make this lie a fact in the hearts of tens of thousands of soldiers and civilians in the city. Eight thousand regular soldiers were excited, and tens of thousands of people were also organized and went to the city to help defend themselves.

Three days have passed, and there is no news from Shandong, but everyone believes that it was Marshal Cao's careful and secret arrangement, intending to hide from the enemy. Five days have passed, and I have not seen Zong Bi send troops to the west to block, but everyone still believes that the army of Xiangzhou has dug a grave for Zong Bi's army in the west, seven days have passed, Handan's reserves have not come, ten days have passed, and the offensive of Zong Bi's army is still fierce.

At this time, everyone seemed to think that something was wrong, but the ten days of fighting had made the soldiers and civilians in the Daimyo Mansion forget the fear they had when Zong Bifang came, and there were even thousands of people among the people who had stood out from the experience of war and became qualified soldiers. Although there were casualties every day, and although the situation was still not optimistic, they found that as long as they mustered up the courage, it would not be easy for Zong Bi to defeat them!

Of course, there is a more critical factor, that is, Marshal Cao Guangbi has been standing at the head of the Daimyo's Mansion for the past ten days, braving arrows and flying stones to personally command the battle! He stood there and made the populace of the Daimyo's mansion feel that the marshal had not abandoned them; He stood there, and the regular army of only 5,000 men was desperately conscious.

Finally, the Han generals stationed in Jeju sent a light cavalry to harass Zongbi's rear, and Tanggu also hurriedly dispatched militia from Hejian, Yongjing, Jizhou and other places to the south to help. Seeing that all aspects of the situation had moved, Zong Bi felt that it was difficult to win if he continued to fight, so he retreated after launching the last unsuccessful siege.

Under the setting sun, looking at the formation of the Jin army that was about to retreat, Cao Guangbi breathed a sigh of relief, seeing that this terrible crisis was about to pass, an arrow suddenly flew and shot it squarely. The generals hurriedly came to protect, he covered his wound and smiled: "Don't be afraid, not deep." You continue to monitor the retreat of the Jin army, and prevent Zongbi from returning the horse gun. He returned to the house under the escort of the military doctor and was personally cared for by his wife.

After Zong Bi retreated this time, he could no longer force the Han army's Yellow River defense line to the brink of collapse like this time, and the orders of the Yellow River Defense Line General Headquarters to prevent and pursue were issued one by one, forcing Zong Bi back to the south of the Yellow River, and the war that once burned to the north bank of the Yellow River subsided again, and the land of Hebei calmed down for a long time.

Zong Bi thought that it would be difficult to defeat Cao Guangbi alone, so he hurriedly asked Zhao Gou for help, asking him to march into Shandong and Weinan to flank the Han army. But Zhao Gou was photographed by Cao Guangbi's prestige, and saw that Cao Guangbi was able to defend the Yellow River so tightly with a limited number of troops, thinking that even if he really waved his army north, he might not be able to cross the river easily. What's more, Yang Yingqi's smile is still hanging in Xiaoyan Fuyuan, thinking about the smile that bloomed on the white face that he had never met, Zhao Gou felt furious in his heart!

"However, in such a situation, you can't do nothing."

At this time, Zhao Gou remembered the voice of some scholars under the rule of the Great Song Dynasty: "Suppress Jin Kou!" Revenge! Restore the old capital! ”

Perhaps, at this time, it will be much safer and more cost-effective to unite with Cao Guangbi to deal with Zong Bi than to unite with Zong Bi to deal with Cao Guangbi.
