From July 205 to October of 06, Chen Deng spent a year to restore order in Youzhou, promoted some capable talents in Youzhou, and cracked down on nearly 100 families and bullies who were evil, and soon Chen Deng won the support of the people of Youzhou. After stabilizing the situation in Youzhou, Xuzhou General Commercial Bank quickly started a commercial bank in the main cities of Youzhou, and a large number of Xuzhou products flocked to Youzhou, and the paper that was originally fried to 1 tael of silver can now buy nearly 100 pieces of silver, which made the literati of Youzhou cheer.

As they thought, in the second year of the establishment of Youzhou Mansion, Chen Deng accepted Peng Cheng's entrustment to establish nearly seven schools in Youzhou, including Youzhou School and Youzhou Huatuo Medical Hall. The people of Youzhou, like Liaoning Mansion, also welcomed their happy life of having books to read! One task after another was carried out as before, until October, when Chen Deng was the busiest, and suddenly someone came to report to the envoy of the senior cadres of the state to ask for a meeting!

Hearing that it was a matter of merging the state, Chen Deng did not dare to be sloppy, and hurriedly summoned the envoy of the state. It turned out that Cao Cao was very anxious to attack and annex the state, all the way to Huguan, Huguan Taihang Mountain generation, is the gateway to the north, so Gao Gan has been operating for a long time. Cao Cao couldn't attack repeatedly, and he didn't want Yuan Shao to surrender Lu Kuang and Lu Xiang to deceive the two people to open the city gate, so Gao Gan lost the pot and closed the city.

In the battle of Shangdang Huguan, the elite of the senior cadres were lost, so the senior cadres wanted to take refuge in Youzhou Chen Deng to get a glimmer of life. After the defeat of the Battle of Huguan, Gao Gan knew that he could not hold the state without soldiers, so he wanted to go north to Wuhuan, and the king of Wuhuan was afraid of offending Cao Cao and did not dare to take Gao Gan in. So Gao Gan wanted to go south to join Liu Biao in Jingzhou. He did the same in history, and was caught and beheaded by Cao Jun on the way.

Bingzhou is so far away from Jingzhou, everyone persuades that Gao Gan is not as good as Yuan Tan, the eldest prince of Dongtou, and he is also a relative. But the state to Bohai County across the entire Jizhou, think about it, such as the princes who dare to offend Cao Cao today are Xuzhou Tao Ying, Jingzhou Liu Biao and Yangzhou Sun Ce, so Gao Gan wants to choose the principle of refuge nearby and take refuge in Tao Ying!

After meeting with the envoys of the senior cadres, Chen Deng did not dare to make decisions on his own. So Chen Deng wanted to send a messenger to inform Tao Ying of Xuzhou, and Gao Lan, the military and political governor of Youzhou, was acquainted with Gao Gan, so he said that if he went to tell the lord, he would die in the state! Will be outside, the king's order will not be affected, not to mention that now is a time of crisis? Chen Deng thought about it carefully, the land of the annexation is Lu Bu's hometown, and it also has a relationship with Xuzhou, if he does not save the annexation at this time, he may be occupied by Cao.

Therefore, after a day of discussion, Chen Deng allowed Gao Gan to surrender, and sent Gao Ran to lead an army of 5,000 to block Cao Cao's army and horses going north. After Gao Ran led the troops to set off, Chen Deng sent people to inform Xuzhou Mansion day and night, and at the same time wrote letters to Liaoning Prefecture and Bohai County, Jizhou Prefecture, which were closest to him, asking Liaoning Prefecture to increase troops to support Youzhou.

Here, after Cao Cao had just defeated Gao Gan in the battle of Shangdang, Gao Gan had no choice but to lead the rout army north. Strategist Guo Jia suggested that it was better to allow Gao Ran to surrender, and if he forced Gao Gan, I was afraid that he would surrender to Tao Ying and make a wedding dress for others.

Cao Cao also knew Gao Gan's temperament, but he was afraid that he would force Gao Gan to go to Youzhou, so he hurriedly stopped his troops and sent people to say Gao Gan. As soon as the envoy arrived at the Gao Gan camp, he learned that Gao Gan had surrendered to Youzhou, and Gao Gan's banner had been replaced by the banner of Xuzhou!

Not only that, but even the city north of Huguan also rushed to make the Xuzhou banner one after another, and then inserted it into the city wall in exchange for peace. Cao Cao once had a defeat agreement with Xuzhou, and the two sides would not invade each other, and Tao Ying once told Cao Cao that as long as the Xuzhou banner was erected, if Cao Cao attacked, Tao Ying would cut off all his food and grass supplies, and at the same time lead all the soldiers and horses in Xuzhou to fight with Cao Cao to the end!

Therefore, the land of the annexed state rushed to make flags overnight, indicating that they had taken refuge in Xuzhou, they were already the people of Xuzhou, and Xuzhou would give them the rights of citizens and ensure their safety!

The envoy returned to see Cao Cao, and Cao Cao was extremely angry. He lost the entire Youzhou, and finally went north to defeat Gao Gan, how could he let the land of the state fall into the hands of Xuzhou?

Therefore, Cao Cao ignored the advice of Chen Deng's envoy and continued to march north to attack other cities in Shangdang County, in a vain attempt to capture Shangdang and then continue north. After hearing that Cao Cao continued to send troops, Gao Ran hurriedly led his troops and Gao Gan into Xiangyuan to defend Xiangyuan. Cao Cao's troops surrounded Xiangyuan, Gao Ran let people strengthen the city wall, Cao Cao attacked for nearly half a month and still did not capture Xiangyuan City.

In the blink of an eye, the time went from October to November, and the winter in Bingzhou came unusually early, and the north wind was blowing, which made Cao Jun feel deeply tired.

Seeing that the soldiers and horses of Xuzhou were stationed in Xiangyuan, they could not attack it for a while, and the cold winter was coming again, Guo Jia suggested that Cao Cao might as well return to Xudu to watch his fight. Now that he has merged with the state, although the senior cadres have suffered heavy losses, with his influence in the state, he will re-recruit a team of soldiers and horses in less than half a year, and he will definitely not succumb to Xuzhou at that time, so he will definitely rebel against Xuzhou again.

If the attack is too urgent, Gao Gan will twist into a rope with Gao Lan, and if it continues to fight like this, Yanzhou will be greatly injured, and it will be cheaper for Xuzhou Tao Ying.

Cheng Yu also persuaded Cao Cao, and in desperation, Cao Cao withdrew his troops and wanted to return to Xudu, leaving Yuan Shao to surrender to Lu Kuang to guard Huguan.

When Cao Cao retreated, Gao Gan breathed a sigh of relief. From Youzhou to Xuzhou, it took nearly half a month for the envoy to go to the post station to deliver the letter to Tao Ying's hand.

Hearing that the state surrendered, Tao Ying was very happy in his heart. But the strategist said that Gao Gan was not really surrendering, he was Yuan Shao's nephew, and he had the idea of becoming a king in his bones, and he would not surrender to Tao Ying at all.

Tao Ying asked Jia Xu again, Jia Xu said that it is better to recruit high-level cadres to come to Xuzhou, if high-level cadres dare to come, it is a real surrender, if they dare not come, it is a fake surrender!

So Tao Ying sent a letter to invite Gao Gan to Xuzhou for a while, and after the messenger departed, Chen Deng's messenger said that Cao Cao kept dissuading, and still attacked the city of Bingzhou with the banner of Xuzhou. Hearing that Cao Cao was holding on to Juye's covenant again, Tao Ying was extremely angry, and wanted to break off diplomatic relations with Cao Cao on the spot, raising troops to attack Cao Cao!

Everyone persuaded that Jia Xu said that Cao Cao's troops are now all long-fought divisions, and now there are still three cities of Bianjing in the hinterland of Yanzhou, if Cao Cao is attacked, Cao Cao will inevitably send troops to attack the three cities, these three cities have thousands of assets, and the gains outweigh the losses!

But if you don't fight Cao Cao, it's hard to understand that you only hate in your heart! Tao Ying's dream has always been to start a war against Cao Cao to avenge his shame for so many years, but he has focused on industrial reform, and now Xuzhou is strong enough to win the Central Plains, where is he willing to guard Cao Cao's anger?

Seeing that Tao Ying was determined to expand the territory was very heavy, Jia Xu saw that now that the state had just fallen, if Cao Cao was attacked, it would be inevitable that the high cadres would rebel, and then Cao Cao would unite with Sun Quan, and the development of Xuzhou for several years would be ruined!

If you attack Cao Cao, you must first stabilize the north and merge the state, this is an inevitable policy!
