Xiang Ao thought that Cao Cao would ally with other princes and princes to fight against Hebei. But Xiang Ao forgot that Cao Cao's favorite thing in history is to pay the world, and first stink other people's reputation.

Before Cao Cao's Northern Expedition, he handed over the world, saying that Xiang Ao did not obey the will of the first emperor, stuck to the northern frontier, and waved his army south, and his intention to usurp the Han was obvious to the world. The princes and princes of all walks of life originally tacitly did not mention this matter, and each of them relied on their own abilities, and the people of the family naturally understood the truth. As for the thoughts of the people, they did not let the princes of all walks of life pay attention.

I don't want Cao Cao to make trouble at this time, and bring such an unseemly thing to the table.

"General Gao, don't you know the defense line of Baima and Puyang?"

"Sacrificial wine, most of the elites of the East County have been placed around the two cities. Xiancheng (south of present-day Puyang County, Puyang City), Wating (present-day western edge of the Nanyang Basin in present-day Henan Province), and Yanxian (present-day northeast of Yanjin County, Xinxiang, Henan) also arranged a lot of Tuntian reserve soldiers and horses to form horns. Gao Shun explained to Jia Xu while pointing back and forth on the map.

"Sacrificial wine, didn't the lord tell Cao Cao to show weakness before, introduce Cao Cao's main force into the hinterland of Jizhou, and surround and annihilate him?"

Hearing this, Jia Xu raised his head to look at Gao Shun, who looked puzzled, and sighed softly and said, "This time and that time." Originally, the lord wanted to take advantage of Cao Cao's ignorance of the situation in Yanguo to force Cao Cao to raise troops to the north, so that Cao Cao's main force would be buried in Jizhou and eliminate Cao Cao's living force. But before Cao Cao sent his troops, he handed over the text to the world, saying that the lord had disobeyed the edict of Emperor Ling of the Han Dynasty and sent troops south. ”

"But the Han Dynasty has been..."

"Although the Han Dynasty is dead, the princes of the world still recognize the orthodoxy of the Han Dynasty!" Jia Xu said helplessly: "Since you admit it, you must follow the edict, if you don't follow the edict, it is a rebellion." This is the consequence of being nameless. ”

"In the past, Emperor Liu Hong of the Han Dynasty had ordered the lord not to go south to enter the Central Plains in the court, and now the lord has taken Jizhou, not to mention, but also sent troops to Xiliang. Even if the princes of all walks of life know in their hearts that if there is chaos today, it is up to them to decide who will kill the deer, but the people do not know. ”

"Before the lord left, the plan to invite the king into the urn is no longer available at this time." Jia Xu left the map a few days ago, slowly came to the gate of the Puyang City Mansion, looked up at the south and said: "Since Cao Cao has no virtue and makes the current situation clear to the people of the world, the first battle cannot show weakness to Cao Cao." This battle is about the hearts of the people. ”

After Jia Xu said, Gao Shun nodded a little clearly, and his doubts disappeared, and his face was replaced by a solemn face.

"I'm afraid I'll have to inform the lord quickly."

Gao Shun has followed Xiang Ao for many years, even if Jia Xu analyzes the situation clearly and clearly, but without Xiang Ao's presence in Puyang, Gao Shun still has some confidence in his heart. When Jia Xu heard this, he turned his head and looked at Gao Shun with a chuckle and said lightly: "It is inevitable to inform the lord, after all, Cao Cao's actions will not only affect the situation on both sides of the Yellow River, but the whole world." ”

"The lord is in Xiliang, and he won't be able to rush back to Jizhou for a while, and the two of us have a great responsibility."

"Don't worry about sacrificing wine, and you must fight to the death to defend the lord's hard-earned territory." Gao Shun clenched his fists and said to Jia Xu with a solemn face, his eyes were full of determination, and even with a slight gesture of being ready to die at any time.

"General Gao, don't talk nonsense." Jia Xu smiled faintly and said: "General Gao is a general cultivated by the lord, if he falls here, the lord will not pull out the skin of the lord." ”

"How can the soldiers and horses of Wuyan Country be so easy to get along with?" The corners of Jia Xu's mouth curled slightly, and his face became a little evil, and he said: "General Gao is only responsible for arming, since Cao Cao is like this, then Xu will give Cao Cao a fierce tiger heart!" ”

After that, Jia Xu no longer paid attention to Gao Shun, and came to the map alone, squinting his eyes and staring deeply at the map. Seeing that Jia Xu didn't tell him the strategy, Gao Shun didn't think much about it, after all, his lord valued Jia Xu so much, and he expected that Jia Xu would have a draft to deal with Cao Cao. Gao Shun believes not in Jia Xu, but in his lord, the invincible Xiang Ao.

From the Yellow River in Dongjun to the mouth of the sea, although the water of the Yellow River is not turbulent, the river channel is wide and the field of vision is broad, for the Cao army, who is not good at water warfare, it is not suitable to cross the river to the north. However, the ferry outside Puyang, the seat of the East County Administration, can accommodate tens of thousands of troops to cross the river at the same time, and if they want to go north to attack Xiang Ao, Cao Cao's army must take Puyang in the East County.

In addition to Puyang, at the suggestion of Guo Jia, Cao Cao's army left Chenliu and marched west into Yin, Henan, where he had no belonging. In the east of Yin, Henan, there is the county seat Zhongmu (now Zhongmu County, Zhengzhou City), and dozens of miles north of Zhongmu there are Juan County and Yuanwu County (now the boundary of Yuanyang in Zhengzhou City).

On the banks of the Yellow River north of Juan County and Yuanwu, there is the largest ferry along the Yellow River, Guandu (the Guandu site is located in the area of Guandu Town, 2.5 kilometers northeast of Zhongmu County, Zhengzhou City, Henan Province, but nearly two thousand years later, the Yellow River channel is offset, according to the Chinese historical atlas compiled by Tan Qixiang, Guandu of the Eastern Han Dynasty is more than ten miles away from today's Guandu County).

When Guo Jia proposed Cao Cao to surrender the world and crusade against Xiang Ao, he had already considered that it would anger Xiang Ao, which was likely to cause Xiang Ao to abandon Xiliang and march south to Yanzhou and Yuzhou. At this time, the whole of Henan must be occupied and the ferries along the Yellow River must be strictly guarded. The soldiers are fast, Guo Jia doesn't dare to despise Xiang Ao, since he chose the Northern Expedition, he must make all plans.

After blocking the ferries along the Yellow River and taking Puyang, he was qualified for the Northern Expedition and fought with Xiang Ao.

As for Hanoi, Cao Cao and the others didn't think much about it, the defenders of Hanoi must be elite, and the number is not low. So Cao Cao divided his troops into two routes, let Guo Jia lead the army to attack Puyang, and he led the elite to raid Henan.

Cao Cao was forced to declare war on Xiang Ao, and the princes of all walks of life saw an opportunity. Sun Ce's army of Eastern Wu fought a successful battle, but compared with the infantry of the princes in the north, Sun Ce naturally saw the gap in his own power. After Cao Cao went north, Sun Ce raised a large army to raid Jingzhou, wanting to take advantage of Cao Cao's northern expedition to take Jingzhou and occupy all the states and counties south of the Yangtze River, while competing for the world in the future.

As for Liu Bei, the same scholar Cao Cao, sent the world, displayed Liu Biao's inaction as a royal clansman, sat and watched the chaos in the world, revealed his intention to usurp, and went south to launch a fierce attack on Nanjun (now from Xiangfan in the north to more than 100 miles south of Yichang, Hubei in the south).

If you want to enter Shu, Hanzhong is the best way. But now that Hanzhong is controlled by Lu Bu, Liu Bei doesn't want to anger this tiger. In addition, Sun Ce launched a fierce attack on Jingzhou, and Liu Bei planned to attack Jingzhou from the north and south. As long as you take Nanjun, you can take advantage of the Yangtze River to enter Ba County (most of present-day Chongqing Municipality and western Sichuan), and enter Guanghan and Shu Counties (present-day northern Sichuan Basin).

However, Yizhou not only has Liu Bei staring at, but Lu Bu, who is more convenient, naturally regards Yizhou as his own meal, how can he let others get involved. However, Liu Bei's intentions are not obvious now, and Lu Bu has not made much action for the time being, as if he is waiting for a good opportunity.

The princes of the Eight Roads, under Cao Cao's submission, moved one after another. The world, which has been quiet for several years, is in chaos again.

Leaving aside the southern part of the Central Plains for the time being, Cao Cao's army, which was trying to take Henan Yin, crossed the Xuanyuan Pass and collided with the southern army of Yanguo in the south in the area of Yanshi (now the central and western regions of Henan Province, Songyue in the south, and the Yellow River in the north).

"Childe, the scout is here to report, there is Cao Jun in Yanshi City!"

"Cao Jun?!" Xiang Ping exclaimed slightly, Cao Cao's document had just come out, and the army had already appeared in the hinterland of Henan, Xiang Ping didn't have time to think about it, so he quickly ordered someone to take out the map and look at it carefully.

"A hero is a hero!" Xiang Ping sighed a little convincingly, and ordered solemnly: "There are three armies, march at full speed, and enter Luoyang!" ”

"Order General Zhang He, the Taishou of Hanoi, to cross the river immediately and occupy Chenggao City and Tiger Pass!"

"Childe, it's not proper!" Han Hao, who was accompanying him, hurriedly stepped forward to dissuade him: "Cao Cao sent troops to Luoyang, he must have planned to occupy Henan and strictly guard against the crossing of the Yellow River. Since Cao Cao's army has appeared in the Yanshi area, the Rongyang and Chenggao areas in eastern Henan must have been occupied by Cao Cao's army. General Zhang He should strictly guard the ferry ports along the Hanoi coast at this time. ”

Looking at the anxious Han Hao, Xiang Ping chuckled and said, "General Yuanhei is right. As soon as the document was issued, Cao Jun appeared here, and you can imagine how anxious Cao Cao was. Compared with the soldiers and horses of Wuyan State, Cao's army must be a little weaker, if so, why did Cao Cao take Henan to expand the defense line? General Yuan Hei thought that Cao Cao had so many soldiers and horses to arrange the defense line at this time? ”

"Uh..." Han Hao was speechless for a while, and said with some doubts: "Then why did Cao Cao do this?" ”

"Guandu!" Xiang Ping confidently pointed to the Guandu on the map and continued: "Along the Yellow River, the largest ferry is Guandu. If Guandu is in hand, tens of thousands of soldiers and horses can be transported across the river in one day. Cao Cao sent troops to the Northern Expedition, and he should have joined forces to capture the ferry and extradite the army. ”

"Although Guandu is large, compared with the ferry outside Puyang City in Yanzhou, Guandu should not be so important to Cao Jun." Xiang Ping roughly pointed to the princes around Cao Cao on the map and continued to say to Han Hao: "In this case, Cao Cao will not raise troops in Luoyang because of the gains and losses of a county, except for lengthening the defense line of the Cao army, it will not be of any benefit to the Cao army. ”

"In my opinion, Cao Cao's dispatch to Luoyang this time is just an illusion, and Cao Cao's goal is to take Rongyang and control Guandu. Cao Cao abruptly issued a document, explaining the current situation to the people of the world, and wanted to trap my father in an unkind and unjust situation, and he must have been worried that my father would be angry and raise troops, so he gave up Xiliang and went south. ”

"If the lord is angry and the army goes south, wouldn't Guandu be more important to the lord?" Han Hao was taken aback and shouted in a low voice: "If this is the case, Gongzi should quickly order General Zhang He to cross the river and occupy the south bank of Guandu!" ”

Xiang Ping looked at Han Hao, who was startled, and was a little speechless. Before Xiang Ao left, he had told Xiang Ping to listen to Han Hao's opinions, but Han Hao's current performance made Xiang Ping a little disappointed.
