In August, most of the Zhang Jaw entered Wuling, entrenched in the mountains to guard the main road, and after learning the news that Cao's soldiers and horses had entered Jiaozhou, he sent a message to inform the Zhao Palace of Handan, and on the other hand, he prepared troops and horses to march to Jiaozhou with Li Damu and others as the advance army.

In the same August, Zhang Liao in the east also marched into Lingling County, but there were still sporadic rebels in Lingling County who attached themselves to the Cao clan and resisted stubbornly, and Zhang Liao's troops were still fighting and could not immediately move south to Jiaozhou.

In fact, even if they don't fight, it will be difficult for them to enter Jiaozhou.

The increase in communication between people leads to the formation of village settlements, and the centers of settlements eventually form cities for the sake of war or politics or economy, but no matter how many reasons there are for the formation of cities, the ultimate goal is to the best teacher - survival.

People built cities to survive.

In Jiaozhou, this situation is even more obvious than in the north, they not only build cities to defend themselves like the north, in fact, in addition to war, their biggest enemy comes from miasma. Since ancient times, rivers and transportation have been essential conditions for the formation of cities, and rivers can bring fertile land, as well as sufficient defense and daily necessities. But in Jiaozhou, rivers can also form swamps, bringing miasma.

Therefore, the ancestors built cities in the upper reaches of the river to avoid the miasma. Over time, the city became more and more prosperous, and the downstream swamp became larger and larger. Mosquitoes get an excellent breeding ground, further increasing the destructiveness of the miasma, which is the result of human selection in difficult conditions.

People can take advantage of the time and the place, not because of how strong they are, but because of their intelligence.

And smart, in the human group of this era, Cao Cao is the best.

The city of Lipu captured by Cao Cao was located in the northernmost part of Cangwu County in central Jiaozhou, bordering the main road of Jingzhou, and coincidentally, it was not part of Shixie's sphere of influence. In fact, before receiving the support of the Yan clan, Shi Xie's sphere of influence was limited to Jiaozhi County, and it was not until the eldest son was sent to Handan that the imperial court handed him over to the four counties of Jiaozhou and granted Shi Xie the official position of Jiaozhou pastor. Where he can't control himself, Yanbei has always been very generous.

After Shixie settled the west of Jiaozhou, he raised troops to Yizhou, which gave Cao Cao the opportunity to smoothly control Cangwu County, and at the same time attacked the Nanhai Taishou Shiwu, trying to expand the sphere of influence to the east, but Cao Cao was touched by a nose in just one month.

Originally, Cao Cao hoped to send troops to the east, first controlling the two or three cities bordering the two counties to guard against the soldiers, and then slowly pacifying the county, but he obviously underestimated the difficulty of marching in Jiaozhou.

In this land, the northern soldiers were inherently inferior to the Jiaozhou soldiers, and the biggest enemy of the Cao army was not the southern navy under the Shiwu subordinates, but the miasma from the ubiquitous mosquito bites.

They don't know when they're going to get infected with the miasma, and they don't know how to treat it.

The first battle, the soldiers on the march to the road was seriously ill, the supreme city was unable to attack the city, there was a heart to withdraw but the grass startled the snake, attracting Shiwu to attack, fortunately Shiwu in Jiaozhou the sergeant in the armor combat power is not as good as Cao Jun, this is in the follow-up troops to resist the attack, but Gaoyao County has belonged to the South China Sea Taishou Shiwu.

After this battle, Cao Cao no longer wanted to quickly unify the counties, and after occupying several counties in Cangwu, he focused on building the city in the waters of the lower reaches of the northern part of Lipu City, and then recruited soldiers to transfer craftsmen and seize wealth to store the fields.

It doesn't matter if Cao Cao is good or bad, in this case he has to do these things.

Then there were fools who rushed over from Jingzhou to attack the city, and then attacked countless people in the Japanese army who were infected with miasma, and had no choice but to retreat and return. It was not Zhang Jaw who came all the way to be a fool, but Li Damu, who was sent to the front by Zhang Jaw, and Pan Ling, who volunteered.

Li Damu didn't talk about it, when it came to the fact that the commander of the infantry army was also a general, Pan Ling, who volunteered, was a little interesting. He believed that he was born as a bandit in Liaodong and was familiar with mountain warfare, so he volunteered to earn a credit for himself before the world was calmed down.

At this time, as long as the clear-minded Yan generals know what the situation is, the world is calm, and there will be no battle in the future. What's more, even if there is a war in the future, it will be much more complicated and difficult than the current war, and in the future it will be a foreign war, and there will not be many opportunities to beat the water dogs like now.

How do you know that Pan Ling was dumbfounded when he rushed into Wuling with his headquarters...... Is this a mountain in Wuling? It's completely different from the mountains of Liaodong!

The mountains in Liaodong are high, but there is a way to go up the high mountains, but what is there in this Wuling? The areas that can fight are all valleys, and it is only when he sees Fang Yue's face full of gloom that he breathes a sigh of relief in his heart. It's good that there is no enemy, and if there is an enemy, I will explain it here.

The big words have been spoken, and there is no turning back arrow when he opens the bow, and Pan Ling can only lead the troops to continue to advance, but the recklessness in his heart when he first entered Wuling is completely discharged. Followed by the boring march into Jiaozhou, the first thing to bear the brunt of the Cao clan was to build a few wooden and stone villages to guard the main roads, and a city was enough to garrison hundreds of soldiers, but it was enough to lock the main roads and drive them to those difficult country roads.

There is no need to attack the city garrisoned by a few hundred people, as long as the follow-up army arrives, the stone village can be pulled up in a moment. What's more, they may surrender without a fight at that time, so why let the soldiers take their lives to pile up these small stone villages?

If it was a large city, or seven or eight hundred people were garrisoned, Pan Ling and Li Damu would not dare to act like this, because those soldiers might cut off the back road after they passed. But there are only two or three hundred garrisons, and they do not have this ability.

Pan Ling is still looking forward to them rushing out of the stone village!

It's just that he didn't expect that Cao Cao thought the same way. Cao Cao knew that the Yan advance army would definitely not regard their fortress as a major danger, so he would only take a detour and a detour...... Cao Cao asked the local people in Jiaozhou that the more country roads that no one walked, the greater the possibility of encountering miasma.

This kind of thing can't be avoided even by the locals in Jiaozhou, except for those who are born with miasma, two or three of the others will not survive as long as they have miasma. Even if you survive once, what about two or three times?

These foreigners from the north, no matter how sharp their armor and how powerful their momentum is, they may not be able to escape the fate of being defeated by this land in the end.

Before Pan Ling and Li Damu could touch the shadow of the enemy, they were hit hard, so they had no choice but to withdraw to Jingzhou and inform Zhang Jaw of the news. Zhang Jaw was also reluctant to try the strength of the miasma, hoping to hand over this difficult stone to Shixie in Jiaozhou to clean up, and immediately left a few soldiers and horses to guard Wuling, led the army back to Nanjun, held the intersection leading to Yizhou, and sent people into Yizhou to find Shixie to inform him of the news.

But Cao Cao's laughter in Lipu hadn't been long before he received a message that made his smile freeze.

Zhang Liao's forward troops and horses have been stationed in Nanhai County and converged with the Shiwu Department, the good news is that Zhang Liao has no plans to attack further west, and the bad news is ...... Shiwu's Southern Navy put on the Yan's iron armor and picked up the Yan's crossbow.
