Although Cao Ren and Han Hao, who were in Changyuan County and Yan County, had few soldiers and horses, they were able to defend the city effectively and actively defend, so they did not let Lu Bu and Zhang Liao succeed.

Zhang Liao can be said to have few soldiers and horses, and he did not do his best, and he had a lot of worries in his heart, so the attack was slow.

Lu Bu attacked more than once, and sent his fierce generals Cheng Lian, Song Xian, Hao Meng and others to personally lead troops to rush forward to boost morale, but they could not break through Cao Ren's defenses, and the city could not be broken for three days and three nights.

On July 30, reinforcements arrived.

Xi Zhong took Guo Peng's military order and arrived in Puyang with Guan Yu and Zhang Fei and 10,000 elite soldiers.

Cao Cao was overjoyed, and immediately discussed with Xi Zhong, asking Guan Yu and Zhang Fei to each bring 3,000 soldiers and horses to support Changyuan County and Yan County, and then Xi Zhong and Cao Cao together took the remaining 4,000 soldiers and horses to defend Puyang and guard against Yuan Shao's movements.

So Guan Yu led 3,000 elite soldiers to Changyuan County, stationed in the county seat, and strengthened the defensive force.

The addition of 3,000 troops greatly boosted morale, and Cao Ren ordered Guan Yu to lead his army out of the city, destroying in one fell swoop the eight mounds that Lü Bu had ordered to be cast, and frustrating Lü Bu's attack.

On the other side, in Yan County, Zhang Fei arrived with an army of 3,000, strengthened the defense of Yan County, and saw that Zhang Liao had only 5,000 people outside the city, so he led the army out of the city to challenge Zhang Liao.

Zhang Fei saw that Zhang Liao was quite mighty, and invited him to decide the winner alone, Zhang Liao readily agreed, and the two fought with spears, and the battle was won or lost in dozens of rounds.

After three days, Zhang Fei and Zhang Liao were single-handedly decided in the open space outside the city, and Zhang Liao's personal guards and Han Hao in the city were very worried, but they couldn't stop the two heads-up.

Lu Bu couldn't move, but Zhang Liao had no fighting spirit, and the attack was blocked on all fronts, far less smooth than Gao Shun's side.

Lü Bu was very annoyed, and asked Wei Xu to forcibly recruit strong men to be sent to the battlefield, expanding the army to 25,000, occupying an absolute advantage in troops, but still unable to break through Changyuan County.

Under Cao Ren's defense, which had almost no weaknesses, the powerful military general Lu Bu felt a trace of powerlessness.

Lu Bu's powerlessness set off Cao Ren's awakening.

It seems that under this high-pressure environment, Cao Ren has awakened a certain will and a certain feeling.

He only felt that with a city wall in hand, he would be invulnerable, no matter what method Lu Bu used to defend the city, as long as there were enough soldiers, he could counteract.

The rain of arrows shot out round after round, the rolling wood and stones smashed down one after another, and the gold juice poured down buckets and barrels, and all kinds of means emerged one after another, making Lu Bu's superior forces like decorations.

Cao Cao supervised the production and transportation of materials needed for the war in the rear, without the slightest mistake.

Sufficient supplies and grain and grass gave Cao Ren enough confidence to spend with Lu Bu, but Lu Bu felt that he did not have enough time and Cao Ren to continue to consume.

So Lu Bu personally went into battle with a big shield, boosted morale, and led the army to storm Changyuan County, the intensity of the siege increased sharply, and the whole day of uninterrupted onslaught, finally filled the trenches outside the city, and the army swarmed in.

Just seeing the dawn of victory, Lu Bu was expelled by the hot gold juice again.

Cao Ren didn't know how much hot gold juice he had prepared, but the moment Lu Bu's army rushed under the city wall, his brains poured down.

At that moment, the entire battlefield was filled with a strong aura of reincarnation of grains.

Lu Bu couldn't stand it anymore, so he had to retreat to the base camp, roaring in the barracks, incompetent and furious, scolding Guo Peng and his subordinates for being shameless.

Lu Bu was lucky, but he was smoked back, and a considerable number of Lu Bu's soldiers were burned by the golden juice, and there was no cure, and they died of festering soon after.

The abundant grain and grass gave Cao Ren the confidence to use a large amount of gold juice.

Every day, the soldiers in the city poured out of the Yoneda Gong were collected as strategic materials and used to defend the city, and anyone who dared to defecate in the open was whipped up.

Although the smell is relatively unpleasant, you will get used to it when you smell it.

Cao Ren now feels that this thing is really a weapon for defending the city.

As long as this thing was smoking on the city wall, the soldiers of Lu Bujun did not dare to approach the city wall to build a ladder, and only dared to hide in the distance and shoot arrows, which could not really shake the city defense system at all.

As for the matter of digging tunnels, after Guo Peng told them in detail about the past battles, Cao Ren was very concerned about this matter, buried listening urns under the four city walls, sent people to monitor day and night, and reported to him immediately when he heard strange sounds.

Luckily, I didn't hear any strange sounds.

Cao Ren's ironclad defense made Lu Bu powerless, and gradually, Lu Bu's sharp spirit was bruised, and he stared at the not tall city wall, and began to doubt whether he could break through here.

If it weren't for Gao Shun's successive good news deliveries, saying that he had successively attacked Jiyin County and Shanyang County, Lu Bu really felt that he could pack up and go back.

If you can't take a city, what kind of invader can you be?

O invaders, aggression is like fire!

But no matter how much the siege is, no matter how much oppression, this city just can't be taken, or it has been persistent.

Lü Bu's attack was completely frustrated, and he had to stay north of Chenliu County, where it was difficult to advance.

At the same time, in Yuan Shao's camp, there was also a fierce debate.

The cause of the debate was naturally Yuan Shao's move south to attack Yanzhou.

After Lü Buzhen went south to attack Yanzhou, Tian Feng suggested that Yuan Shao immediately send troops south to attack the eastern county of Yanzhou in order to respond to Lü Bu, and join forces with Lü Bu to attack Yanzhou.

Strive to defeat Guo Peng, take Yanzhou in one fell swoop, and turn the situation around.

Xu You and Feng Ji disagreed with Tian Feng's opinion, they just used Lu Bu as a pawn to contain Guo Peng, and they didn't really want to help Lu Bu.

They advised Yuan Shao to take advantage of Guo Peng's busy dealing with Lü Bu and immediately lead his troops north to attack Gongsun Zhan.

"Lu Bu went south to Yanzhou, this is a once-in-a-lifetime opportunity, the general is worried that he will be attacked by the north and the south, so he will try his best to destroy it, Gongsun Chan is just a dry bone in the grave, the real threat is Guo Peng, if Guo Peng's strength can be greatly weakened, Gongsun Chan will be vulnerable, I think this is the right one."

Tian Feng tried his best to advocate that Yuan Shao immediately send troops south to attack Dongjun, respond to Lü Bu, and sweep Yanzhou, so that Guo Peng could not be defended.

Xu You and Feng Ji have always disliked Tian Feng and tried their best to dissuade Yuan Shao.

Xu You said: "The general asked Lu Bu to go south to attack Yanzhou, just to let Lu Bu, the tiger, devour Guo Peng, the evil wolf, and the wolf and tiger compete, and the general can get the opportunity to attack Gongsun Chan and completely pacify the rear. ”

Tian Feng was furious and said, "You have mistaken the general's great cause!" Guo Peng is the real obstacle to the general's great cause, Gongsun Zhan is just a side of the settlement, with the scarcity of Youzhou household registration, where is the qualification to compete with the general for Hebei?

Guo Zifeng occupies the Qingyan Erzhou, backed by the Yuan Highway, the rear is worry-free, once the preparation is over, he will inevitably go north to invade the general's Jizhou, how can he compete with the Qingyan Erzhou with the power of Jizhou? If Guo Zifeng is not weakened at this time, when will he wait? ”

Xu You was also greatly annoyed.

"The general's great cause is to capture Hebei, take Hebei as the foundation, let the rear worry-free, and then look down on Guo Zifeng with Hebei's advantages, in one fell swoop, you now let the general send troops to Dongjun, isn't this tantamount to admitting that Lu Bu's behavior was instructed by the general? What happens once Lu Bu is defeated? ”

Tian Feng pointed at Xu Youqi's face turned red.

"If the general doesn't support Lu Bu, Lu Bu's puppet will definitely be defeated! Now that he has driven Lu Bu to attack Yanzhou, he must use Lu Bu's blood and courage to join forces to attack Yanzhou and cut off Guo Zifeng's arm, so that he naturally has no time to go north to invade Jizhou! ”

Xu You said contemptuously: "Ridiculous! Gongsun Chan is eyeing me behind me, Guo Zifeng's elite is good at fighting, if our army is unfavorable for a long time, once Gongsun Chan comes to his senses, he will definitely go south immediately, and Jizhou will be the real danger at that time! ”

"Xu Ziyuan! You're delaying the general's great cause! ”

"Tian Yuanhao is in vain! You're delaying the general's cause! ”

The two quarreled-for-tat, and the contradiction between the Yuzhou scholars and the local scholars suddenly intensified.

Frustrated Zhu couldn't help it, and also stepped forward to help Tian Feng, Feng Ji also went down to fight with them, and more and more people went down to quarrel, which made Yuan Shao annoyed.
