Zhu Wei was not in a hurry to start a decisive battle with Cao Cao, so he divided into two ways when the army attacked.

All the way, the main force of his Chinese army went straight to the sour jujube by land, seemingly to find Cao Cao head-on, and along the way, he transferred the Jiangjiao battalion of Ganning, and transported the 30,000 troops of the Dongzhou Army to the land of Fengqiu with the help of the Yellow River waterway, thus cutting off Cao Cao's connection with Yingchuan and the land south of Yanzhou.

In this way, the southern area of Yingchuan and Chenliu was basically swallowed by Zhu Weijing, and then the Dongzhou Army divided a partial army of more than 10,000 troops, led by Zhang Ren and Huang Quan, and began to conquer some counties in the south of Chenliu County, and at the same time, it was also to go to Xiangyi to solve the Cao army of Hao Zhao's department, so as to meet Tai Shici and Zang Ba's department to continue north.

At this time, the Huainan battalion of Huang Zhong's headquarters had easily subdued the counties and townships in the land of Chen, and the army immediately turned north and marched in the direction of Chenliu.

Huang Zhong didn't know that Tai Shi Ci and Zang Ba were stopped in Xiangyi by Hao Zhao, and according to the original agreement between him and Tai Shi Ci, they should go all the way north after Chen Liu's army, so that they could join the main force of Zhu Wei's army.

If you look at it from the map, several armies of Zhu Weijun can be said to have outflanked Cao Cao on the side of Sujujube.

However, Cao Cao waited for the convergence of the army of Changshe brought by Xiahoudun on the side of Sour Zao, and gathered about 50,000 or 60,000 regular troops, plus nearly 30,000 or 40,000 young and strong new troops, and then did not stay any longer and retreated to Puyang City.

Because Cao Cao had already had a military strategic arrangement, a lot of grain and grass materials have been stored in Puyang City today, plus the nearly 90,000 troops brought back by Cao Cao, it seems that there is a good defensive force.

Therefore, as long as Cao Cao can use Puyang City to block the attack of Zhu Weijun, then Cao Cao can hold out in Puyang City for one or two years.

It's just that in the face of Cao Cao's retreat tactics in such a big stride, Zhu Weijun still advanced steadily step by step, which made some of Cao Cao's ambush counterattack methods left in the rear meaningless.

After the main force of Zhu Weijun retreated from Suozao, he stopped in Suozao, and duly separated the Hanzhong Army to capture the northern counties and townships of Chenliu County, ensuring that Chenliu County was in his hands.

Subsequently, the Hanzhong army was also ordered to attack Jiyin County to deal with Dong Heng's troops left by Cao Cao, and the 20,000 troops of the Hanzhong army were theoretically enough to deal with Dong Heng's troops of less than 10,000.

Then Zhu Wei was waiting for Huang Zhong, Tai Shici and the Dongzhou army that had been separated before to come back and converge, Zhu Wei was obviously not in a hurry about the war, and was only ready to gather all the troops before going to Cao Cao for a decisive battle.

In this way, around September 13, 199 AD, Zhu Wei converged the Dongzhou army that had been separated before in the land of sour jujubes, and gathered Huang Zhong and Tai Shici from Xuzhou, almost concentrated nearly 14 or 50,000 troops, and then slowly approached Puyang City, where Cao Cao was stationed.

And when Zhu Wei's army attacked Cao Cao, Cao Cao naturally sent a letter of help to Yuan Shao as soon as possible, and after Cao Cao led his troops to Puyang City, he sent more than a dozen letters for help to Yecheng, where Yuan Shao was.

But at this moment, Yuan Shao was also regretting his previous withdrawal of troops, if it weren't for his withdrawal, Zhu Wei would not have found a chance to eliminate the 50,000 troops he left on the north bank of the Yellow River.

If he hadn't withdrawn his troops, then it would be impossible for Zhu Wei to send a few cavalry into Youzhou and Yizhou to harass his hinterland, because Zhu Wei would inevitably concentrate the main force and fight him in a decisive battle.

In this way, he does not have to worry about organizing an army to encircle and suppress the cavalry that enters his own territory, and he can have a face-to-face fight with Zhu Wei on the north bank of the Yellow River.

If he hadn't withdrawn his troops, Zhu Wei wouldn't have dared to attack Cao Cao with such fanfare, then Cao Cao would still be able to help him contain Zhu Wei now, and he wouldn't let Zhu Wei occupy a large amount of territory like now.

But Yuan Shao's regret is useless, he can only face the current situation.

The loss of 50,000 troops on the north bank of the Yellow River and the death of Chun Yuqiong, a general, were also a little traumatic to Yuan Shao, although he still had more than 100,000 troops on Yecheng's side at this time, but 50,000 troops also accounted for about a quarter of his total strength.

At the same time, Zhu Weijun's Xionglu battalion went north, which also had a great sense of threat to Yecheng, even if the Xionglu battalion was still defense-oriented, but the best defense was to attack.

Under Zhuge Liang's plan and with the support of Pang Yan, the Xiong Lu battalion directly attacked and harassed the territory of Wei County in Yizhou, and even approached the outer areas of Yecheng.

This made Yuan Shao have to send troops to the border to set up defenses to stop the Xionglu battalion's attack on Yecheng.

Now the whole situation has changed, it was originally Yuan Shao's army that threatened Luoyang City, which Zhu Wei occupied, but now it is Zhu Wei's army that threatens Yuan Shao's base camp Yecheng, how could Yuan Shao withdraw his troops if he knew this.

And the Fubo battalion of Ma Teng's headquarters and the tiger wing battalion of Zhang Xiu and Zhang Liao sent by Zhu Wei to Youzhou and Yizhou, plus the cavalry of the Southern Huns, made Yuan Shao feel like eating a fly.

After Ma Teng led the army into Youzhou, he could only occupy some counties and townships first, and steadily expand his influence in Youzhou, which could not bring much loss to Yuan Shao for the time being.

But Zhang Xiu, Zhang Liao's Tiger Wing Battalion and the Southern Hun cavalry entered Yuan Shao's hinterland in Yizhou.

Perhaps the heavy cavalry and light cavalry of the Tiger Wing Battalion to which Zhang Xiu and Zhang Liao belonged could still be restrained because of military discipline, and at most they plundered official materials, but they would not cause much damage to the local area.

But those Southern Huns fought completely for plundering, and they were completely burning and looting all the way forward.

Under Zhu Wei's instructions, after Zhang Xiu and Zhang Liao took the Southern Huns into Yizhou, they also divided their troops and moved, so the Southern Huns, who had lost their restraint, completely regarded this trip to Yizhou as a robbery trip for them.

According to the route given by Zhu Wei, the Southern Huns first directly entered Zhao County, and then came in the direction of Wei County, seemingly to assist Zhu Wei's Xionglu battalion, causing a flanking attack on Yuan Shao in Yecheng from the north and south.

In fact, when Zhu Wei said to the Southern Huns, he also said that this time he was going to conquer Yuan Shao first, so the Southern Huns really thought that they were going to help Zhu Wei's army attack Yecheng.

In fact, Zhu Wei just fooled them to fight against the main force of Yuan Shao's army, so the cavalry of the Tiger Wing Battalion led by Zhang Xiu and Zhang Liao entered Changshan County, and then went to Zhongshan Kingdom, Hejian Kingdom, and Bohai County.

Zhu Wei hoped that they could contact Cai Mao's navy on the side of Bohai County, so as to bring Zhu Wei's military order to Cai Mao, and let Cai Mao be responsible for sending supplies to them by sea.

Because Ma Teng, Zhang Xiu, and Zhang Liao went deep into the enemy's territory to attack and harass this time, grain, grass and materials could only be obtained on the spot, and it was impossible for Zhu Wei to provide them with logistical support.

Therefore, if they want to fight for a long time on the Yizhou side, they must find a logistics supply line, so Cai Mao's army, which has already explored the coastal route, can help them provide some supplies when necessary.

As for the Southern Huns, they didn't care about them at all, anyway, they were originally out to loot, so they had long been accustomed to looting grain, grass and materials on the spot.

Under Zhu Wei's arrangement, the Southern Huns were completely unaware of the situation and plundered all the way to Yecheng, and Yuan Shao was also angered by the actions of these Southern Huns, so he naturally sent troops to deal with the Southern Huns.

In this way, Yuan Shaojun started a big battle with the Southern Huns on the side of Handan, Zhao State, and as a result, the Southern Huns hit the wall again......
