As the gateway to Xudu, the Changshe is not too far from Xudu.

Zhao Feng was worried that Cao's army would set up an ambush along the road, so the march was not fast.

This is not too far away, Zhao Feng led his troops to walk for five days before he officially approached the city of Xudu.

Xudu was originally just an ordinary county seat, not a big city, and there were only two city gates.

But seven years have passed since the first year of Jian'an.

Therefore, Xudu has expanded several times, and now Xudu has four city gates, and the walls of each city gate are about five and a half zhang high.

Because from a distance, Zhao Feng felt that the city wall of Xu Du was slightly shorter than the city wall of Luoyang.

You must know that the city walls of Luoyang and Chang'an belong to the two largest cities with the highest city walls in the entire Han Dynasty, and the height of the city walls is only six zhang.

If it weren't for the limited level of construction at present, Zhao Feng estimated that with the character of the emperor, it was estimated that he would want to build it to nine zhang, or nine and a half zhang.

And for such a fortified city, it is impossible to smash the city wall with only the catapults made at the current level.

Not to mention the catapults made at the current level, even the catapults made by Zhao Feng himself, I am afraid that it will be difficult to smash the city wall.

Therefore, Zhao Feng ordered to set up camp ten miles outside the northern city wall of Xudu.

As for the eastern, southern, and western city gates of Xudu, Zhao Feng did not plan to besiege Xudu to death for the time being, so naturally he did not order to block the gate.

Anyway, Xu Du was under Zhao Feng's nose, and Zhao Feng wished that Cao Cao would send troops to reinforce the battlefields of other regions, so as to indirectly weaken Cao Cao's main army.

After all, there will inevitably be an army of 100,000 in the city of Xudu!

With Zhao Feng's 90,000 army alone, he didn't want to do anything at all.

Five days later.

Zhao Feng felt that just stationing troops outside the city of Xudu was not a solution.

Although Cao Cao knew that Zhao Feng was coming, the families, Haoqiang, and people in Xu Capital City did not necessarily know that Zhao Feng was leading his troops.

Therefore, from the sixth day, Zhao Feng asked Lu Su, Zhao Yun, Hua Xiong, Wei Yan, Tai Shici, Guan Hai and others to lead their troops to battle under the north city wall of Xudu.

Then let five large catapults, together with the catapults captured from Cao Cao, launch a stone throwing against Xu Du.

Of course, the five large catapults were only tested three times, mainly for the future, to determine some basic data.

After all, five large catapults are used less often than medium-sized catapults.

Even if the five large catapults were all used and scrapped, they would not be able to cause much harm to Xu Du.

Anyway, Zhao Feng's move was just to let the families, heroes, and people in Xudu City know that someone was attacking the city.

In this way, it will naturally bring more trouble to Cao Cao!

Time passed slowly, and three months passed in the blink of an eye.

During these three months, Zhao Feng had his army launch a stone-throwing attack on Xu Du every five to six days.

As for the effect, judging by the appearance, it can only be said that it is average.

But obviously, the three consecutive months of 'siege' will naturally bring a lot of trouble to Cao Cao.

In addition, in the past three months, the armies of all walks of life have also achieved remarkable results.

The army led by Xu Huang and Xiahou Lan has already taken the entire Chenliu County.

Now it has invaded Yingchuan County, and the troops are under the city of Yanling.

Yanling is regarded as the gateway to the northeast of Xudu, once Yanling is taken by Xu Huang and Xiahoulan, then Xu Huang will be able to join Zhao Feng's army in Xudu.

Yanling is the gateway, not to mention too much, there are 5,000 guards, there must be.

But that was just before, and now Cao Cao's situation is very critical, if he catches strong men to join the army in advance, there may be how many people there are now.

If the political work is done well, it is not impossible that the whole city of Yanling will be armed.

And Dian Wei and Wang Ping are also about to take Nanyang County.

As for Zhang He and Wen Chou, it will take some time to take Yuzhou.

this day.

An ordinary soldier ran into the big tent of the Chinese army and bowed his hand to Zhao Feng: "Lord Qi, Xun Envoy, let your subordinates send a copy of the paperwork." ”

After speaking, he handed over the paperwork in his hand with both hands.

Xiong Da took the paperwork directly from the soldier's hand and handed it to Zhao Feng.

After Zhao Feng took the paperwork, he looked at it directly.

The content of it is the result of the discussion between Xun Chen and Liu Biao in the past three months.

That is, Liu Biao asked Zhao Feng to return Nanyang County, and then promised that he would not invade Jingzhou within ten years.

As long as Zhao Fengneng agreed, Liu Biao promised that he would not send troops to help Cao Cao.

If Zhao Feng didn't agree, Liu Biao would agree to Cao Cao's side and choose to send troops to help.

After Zhao Feng finished reading it, he groaned.

I feel that if Xun Chen had not been sent to Jingzhou, Liu Biao might not have sent troops to help Cao Cao.

It was to let Xun Chen go to Jingzhou and let Liu Biao see the opportunity to reap the benefits, so the lion opened his mouth.

Of course, Nanyang County was originally under the jurisdiction of Jingzhou, and Liu Biao's request was excessive, but it was also reasonable.

As for the ten years that Liu Biao asked, Zhao Feng knew in his heart that it was actually to give Liu Biao a smooth handover.

After all, Liu Biao is old and will definitely not live for ten years, Zhao Feng estimates that Liu Biao will only have this or two years, and Liu Biao may think that he still has four or five years.

But in any case, there will not be a ten-year lifespan.

And as long as Zhao Feng made a promise not to attack Jingzhou within ten years, then after Liu Biao's death, Liu Biao's son would be able to take over Jingzhou, and then smoothly pass the most dangerous first few years.

As long as Liu Biao's son sits firmly in the position of the lord of Jingzhou, Zhao Feng will attack Jingzhou again in the future, and Jingzhou will not be without the power to defend the land.

After all, Liu Biao was ordered by Cao Cao to launch an attack on Yuan Shu, and anyone with a discerning eye could see that Liu Biao was preserving his strength.

Therefore, Jingzhou's current army is only afraid that there are many more than Cao Cao!

And Jingzhou is rich in grain production, although there is only one state, but it can raise so many troops.

has more troops than Cao Cao, and only needs to guard the land of a state, as long as Liu Biao's heir is not a waste, he can naturally hold on for many years.

If Liu Biao's son is outstanding, he is not completely inactive.

After all, Jingzhou is a good place, you can seize Yizhou by going west, Yangzhou by moving east, and Jiaozhou by going south.

There are some things that Liu Biao is not good to do for various reasons, but Liu Biao's son has no scruples.

Just like Cao Cao, for various reasons, he did not force Liu Xiechan to give up the throne, but Cao Pi did it.

At the beginning, if Zhao Feng hadn't taken the road of promotion from He Jin, but was personally promoted by Emperor Liu Hong of the Han Dynasty, Zhao Feng would have had a lot of scruples.

Of course, even if Zhao Feng is promoted through He Jin, he still has a lot of scruples.

Unscrupulous, usually don't live long!
