In order to put pressure on Dong Zhuo, Gongsun Kang announced that he would break away from Gongsun Chan and join the Gao Shun forces; Qingzhou Mufangliang announced that Huaiyin County was under the jurisdiction of Xuzhou.

Subsequently, Fang Liang ordered Xuzhou Mu Xu Lin to march into Runan County, eliminate Yuan Shao, and avenge Liu Chong, the king of Chen.

At this time, there were three forces in Yuzhou, namely Yuan Shao, Gongsun Zan and Cao Cao.

As early as the second year of Xingping, Shen Pei and Sun Qian secretly sent an envoy to Yingchuan County, and Cao Cao took refuge in the champion Hou Gaoshun, but he has been holding back and continues to lurk.

After Xuzhou was taken over by the Gaoshun forces, Yuan Shao of Runan County was already frightened and began to plan to develop and grow, and at that time he set his sights on Chen Wang Liu Chong.

Chen Guo has millions of people and nearly 100,000 officers and soldiers, and his strength is stronger than Yuan Shao, so he can't fight hard, he can only outwit.

So, at the suggestion of the military advisor Feng Ji, he first sent a part of the officers and soldiers of the Yuan family, and brought their families to pretend to flee to the Chen State, and lurked and waited for instructions to act.

Yuan Shao followed the advice and sent hundreds of dead slaves to play the role of exiles and flee to the state of Chen.

There were not a few people who fled from Runan County, and Chen Guo was accustomed to it, allocating wasteland to them, providing them with food, farm tools, seeds, etc., so that they settled in Chen State.

In the third year of Xingping, Dong Zhuo had moved the imperial court away from Luoyang, and Yuan Shao felt that Dong Zhuo was temporarily powerless to attack Yuzhou, so he became emboldened and prepared to get rid of Liu Chong and occupy Chen.

In July, the deceased of the family received an order to carry wine and meat to the palace to express their gratitude to King Chen and Xiangguo according to Feng Ji's plan.

The person in charge first toasted King Chen, and then toasted to Xiangguo Luo Jun, the two did not doubt it, but they couldn't excuse it, so they drank the wine that the people toasted, and after a short time after drinking, the two were poisoned and died one after another.

While blocking the news, the dead soldiers sent people to inform Yuan Shao and occupied the palace of King Chen.

Yuan Shao, who had been prepared for a long time, immediately ordered the army to divide into two routes and launch an attack on Chen County, the capital of Chen State, from Ruyang County and Yilu County respectively.

The incident happened suddenly, Chen Guo was unprepared, and Chen Wang Liu Chong and Xiangguo Luo Jun had been poisoned, the dragons were leaderless, and with the assistance of the dead soldiers, Chen County was conquered by Yuan Shao.

During the war, the officers and soldiers of Chen Guo were unable to resist the enemy, and they also joined the evacuation team one after another; Some of the officers and soldiers and civilians of Changping County in the west were evacuated to Chenliu County in Yanzhou, and some were evacuated to Yingchuan County nearby; Officers and soldiers and civilians from Yangxia and other counties in the north withdrew to Yanzhou nearby; Some of the people in the northeast withdrew to the Liang State of Gongsun Chan and the Huaiyin County of Gongsun Kang.

In the end, Yuan Shao only got the population of the four southern counties, more than 500,000 people, and a large amount of supplies in Chen County, which made him very happy.

By the end of August, Gongsun Kang led Huaiyin County to join the Xuzhou forces, much to Yuan Shao's surprise.

Then, Fang Liang issued a letter against Yuan, and then the two armies of Yanzhou and Xuzhou marched at the same time.

Cheng Li estimated that Yuan Shao had just occupied Chen State, and he would not digest it quickly, so he should take advantage of his unstable foothold to eliminate Yuan Shao first and isolate Gongsun Zhan, then Yuzhou could be determined.

Pingyu general Huang Zhong left 5,000 infantry to defend Taocheng to guard against Gongsun Zhan, and he personally led 10,000 cavalry and 5,000 infantry, together with Zhonglang general Yin Li, through Chen Liu, to attack Chen State; Sima Huanglong and Sima Ju, who were stationed in Chenliu, actively cooperated, hoping to obtain enough military exploits and be promoted; Zhuge Xuan and the county guards were in charge of logistics.

The soldiers under the jurisdiction of Gongsun Kang did not have time to be reorganized, Fang Liang appointed him as a lieutenant general, and the soldiers under his jurisdiction were temporarily under his full jurisdiction, and they would be reorganized after the war.

Xu Lin ordered Lang to lead Zhang Meng with 10,000 cavalry and 10,000 infantry to join Gongsun Kang and launch an attack on Runan County from the east; Chen Deng was a military advisor and controlled Zhang Meng and Gongsun Kang.

Yuan Shao was shocked, he didn't expect that Gao Shun, who had never interfered in the affairs of the Central Plains, would suddenly start a war against the princes of the Central Plains, and in the first battle, he Yuan Shao would open a knife, and the two armies would attack, how could he resist?

What scared him even more was that Zhou Fei, the Mu of Liangzhou, and Feng Yong, the Taishou of Hanoi, also sent a message to send troops to quell the rebellion against Yuan Shao; The other kings of Dongping, Ren, and Jinan all condemned Yuan Shao for poisoning King Chen and occupying Chen.

Gao Shun had a good reputation in the jurisdiction, and he was also good to the kings of the feudal states, like Liu Biao committed suicide in Xiangyang City, the second son, the youngest son and other family members were well placed in Shanyang County, returned their ancestral homes, and gave them some land and assets, so that they could live in peace; The families of Liu Miao and Liu Dai were also resettled back to their hometowns; Even Liu Zhang, Yizhou, was sent back to his old house, Gao Shun did not embarrass them, and they were satisfied.

Yuan Shao sent officers and soldiers to defend at the same time, sent envoys to contact Cao Cao and Gongsun Zhan, but these two people, Cao Cao has taken refuge in Gao Shun forces, and Gongsun Chan himself is difficult to protect, he has been surrounded by Gao Shun forces, if he has any changes, Gao Shun's army must destroy him Gongsun Zan first.

Not to mention the garrisons in other parts of the Gaoshun forces, there are Tai Shici's army stationed in Lu State and the Xuzhou army stationed in Pengcheng and Xiapi City, but Xu Lin still has tens of thousands of officers and soldiers in his hands.

Gongsun Zhan hurriedly asked King Liang and King Pei to issue a statement condemning Yuan Shao and drawing a line with Yuan Shao; At this time, he only prayed that the Gao Shun forces would not attack him, and he could no longer care about Gongsun Kang's rebellion.

Cao Cao was even more direct, declaring, who would dare to confront the champion Hou? Even the imperial court avoided its edge and moved away from Luoyang, not to mention that he Cao Cao, tens of thousands of soldiers and horses were not enough to stuff people's teeth.

At this time, most of the hostages of the Cao family and the Xiahou family had been released by Yuan Shao, and there were only a few particularly important hostages in his hands.

Yuan Shao's envoy threatened hostages and ordered Cao Cao to send troops to help.

Cao Cao was unmoved, and declared that if Yuan Shao dared to do so, he would join the forces of the champion Hou and launch an attack on Yuan Shao together; He also threatened Yuan Shao to release the detained family members as soon as possible.

At this time, Yuan Shao's army in the north was stationed in Chen County, Chen State, and prepared to rely on the strong and tall city walls to block the Yanzhou army; The army in the east was mainly stationed on the line of Qian County and Fucheng County and along the coast of the whirlpool; The second line of defense in the east was centered on Ruyin County, and the enemy had to be blocked from Rushui; He had no additional troops to defend against Cao Cao's attack, so Yuan Shao had no choice but to release Cao Cao's entire family and maintain stability between the two sides.

Chen Dengling ordered Gongsun Kang to be stationed in Dan County, and Sima Liuyi of the other department to be stationed in Yan County; Zhonglang General Zhang Meng was stationed in Shansang County, and Sima Zhang Min of the other department was stationed in Longkang County.

Zhang Meng was originally the commander of the Yellow Turban Army, and Zhang Min was the general of the Yellow Turban Army, and the two cooperated and got along well.

Yuan Shao's disaster was not alone, when the north was still deploying troops and actively defending, there was an accident in the south.

Lu Su had already received news from Cheng Li and ordered him to block Yuan Shao's retreat to the south; He found that the defense in the southern area of Yuan Shao was empty, so he decided to take the initiative to attack and take advantage of the fire to rob, which was better than simple defense; Anyang, Xinxi, Yuanlu, Fubo, Shenxian and other counties on the north bank of the Huai River were successively occupied by Lusu.

After Lu Su occupied these places, he immediately transferred his population and wealth to the south of the Huai River, and was ready to evacuate at any time; Sima Jiang Qin of the navy army led the navy to inspect the Huai River, letting Yuan Shao know that Lu Su had been prepared and cut off his delusion of escaping from the south.

The Yanzhou army marched faster, Zhang Meng and Chen Deng had not yet arranged the army in place, and Huang Zhong had already led the officers and soldiers into the Chen state.

The counties in the west and north of Chen Guo are now basically going to the city and are being successfully received by Huang Zhong.

The army continued to move south, easily encircling Chen County.

Huang Zhong had more than 16,000 cavalry alone, and his combat power was super strong, and Yuan Shao's officers and soldiers did not dare to go out of the city to fight, so they had to retreat in Chen County.
