After Zhu Wei received the news that Cao Cao and Yuan Shao would jointly send troops to conscript, he took advantage of the opportunity that the road from Luoyang and Jingzhou had not been cut off by Cao Cao, and sent an order to Wang Yuyan in Xiangyang as soon as possible.

Zhu Wei put Wang Yuyan in charge of the overall affairs of Jingzhou and Yangzhou and the follow-up war in Yizhou, and also put the soldiers and horses left in Jingzhou and Yangzhou under Wang Yuyan's command, so as not to be harassed by Cao Cao's troops in Zhu Wei's rear, and affect the good situation of the war in the west of Yizhou.

Although Wang Yuyan has just given birth and her body is still a little weak, this is just in case, and with Wang Yuyan's ability, it should be no problem to control the situation in Jingzhou, Yangzhou, and Yizhou while cultivating her body.

At the same time, Zhu Wei also sent military orders to the Huainan Battalion of Shouchun Huang Zhong's Department and the Shenjian Battalion of Xuzhou Taishi Ci's Department, once Zhu Wei encountered the joint attack of Cao Cao and Yuan Shao on the Luoyang side, they could wait for the opportunity to move and launch a war against Yuzhou, Gunzhou and other places on their own, and attack Cao Cao's rear.

In addition, Zhu Wei also sent a military order to Zhou Yu, ordering him to command the navy to try to go north along the coastline, so that he could not use Zhu Wei's banner to harass in Youzhou, Jizhou, and Qingzhou, and disrupt Yuan Shao's rear.

Although the navigation ability of the navy is still relatively weak, the warships and warships originally owned by the navy are suitable for navigation in rivers and lakes, and may not be able to travel long distances at sea.

But Zhu Wei still hopes that Zhou Yu can do something, anyway, Cai Mao's navy has nothing to do if he stays in Jiangdong now, it is better to let them go to sea to feel the difference between the sea and the inland rivers and seas.

Besides, it is just along the coastline to the north, and most of the area is also an inland sea area, and the route is actually relatively safe.

As long as Zhou Yu can reach Yuan Shao's northern land with the naval army, he may be able to play the name of Gongsun Zan and disrupt the place, so that Yuan Shao has to withdraw his troops and return to his old base camp to quell the chaos.

Anyway, Zhu Wei mobilized all his troops to deal with the possible Luoyang War.

At the same time, Zhu Wei on the side of Luoyang has carried out a lot of preparation work, to be honest, Luoyang, as the imperial capital of the Han Dynasty, originally chose the site to take into account security and defense.

In the north of Luoyang, there is the Yellow River as a natural danger, and there are Songshan, Funiu Mountain, and Qinling Mountains on the east, south, and west sides of Luoyang respectively, and the pass fortress can be built to resist the invasion of foreign enemies.

Luoyang is known as the "Eight Passes of the Duyi", and there are eight passes around Luoyang, such as Hangu, Yique, Dagu, Guangcheng, Yuyuan, Revolving Gate (Tiger Prison Pass), Mengjin and Xiaopingjin, which are divided into four directions: east, south, west and north to guard the safety of the imperial capital.

Hangu Pass is an important pass leading from Luoyang to Guanzhong, and since ancient times, there is the risk of "one husband is a pass, and ten thousand people are not open".

Hangu Pass was also an important support for the Qin State to fight against the six countries outside the Guanhai in the past, but now there is no need to worry about the attack of soldiers and horses in the Guanzhong Pass, Zhu Wei only needs to send a small number of troops to garrison and maintain contact with the Jingnan Battalion and the Tiger Wing Battalion in Guanzhong.

Yique Pass, Dagu Pass, Guangcheng Pass is the gateway of Luoyang facing the south, but the three customs towns are built in different areas, Yique Pass is built in Luoyang South Longmen Mountain and Xiangshan Quekou, Dagu Pass is built in the valley between Songshan and Longmen Mountain, and Guangcheng Pass is located in the more peripheral Liang County near the dangerous place.

As mentioned above, the location of Guangcheng Pass has basically been abandoned because it is close to the edge of the border between Sili and Jingzhou and Yuzhou, where Luoyang is located, so Wei Yan led the army north to Guangcheng Pass before, and he did not encounter any obstacles at all, and directly killed Dagu Pass, which is only fifty miles away from Luoyang City, which can be regarded as saving some trouble.

When Sun Jian attacked Luoyang, he encountered Dong Zhuojun's resistance at Guangcheng Pass in Liang County, and Sun Jian's first defeat in attacking Luoyang appeared here, but now Wu Xi, who is stationed in Luoyang, has not many soldiers and horses, so it is naturally impossible to send Guangcheng Pass, which is far away from Luoyang, to garrison.

As for Cao Cao's troops, they were all located in Yingchuan County, and he couldn't take into account the defense of Luoyang for the time being, and Cao Cao didn't expect Zhu Wei to attack Luoyang.

In general, as far as the current defense of Luoyang in the south is concerned, Yique Pass is relatively farther north, mainly facing the land of Hongnong in the southwest, so Zhu Wei does not need to send heavy troops to garrison.

It's just that on the side of Dagu Pass and Guangcheng Pass, Zhu Wei needs to send troops to garrison it, so that at least Luoyang and Jingzhou can be connected, and of course, Cao Cao can be prevented from taking a detour to kill him from this direction.

The next Yuyuan Pass and the Revolving Gate Pass are two important passes in Luoyang facing the east.

Among them, the Yuyuan Pass is the key place of Luoyang leading to Yingchuan Xudu, only because the pass is built between the Songshan Taimur Mountain and the Shaomu Mountain, the road leading to the pass is dangerous, there are twelve bends circling in the loop, quite a terrain advantage that will be returned, so that the pass is easy to defend and difficult to attack.

As far as the location of this pass is concerned, it will be an important pass for Zhu Wei to resist the attack of Cao Cao's army in the future, so as to defend the safety of Luoyang.

As for the revolving gate pass, it is located in the northeast of Luoyang the farthest pass, it is built at the confluence of the Yellow River and the Yellow River, the front of the river, the north of the Yellow River, the south of the Song Mountain, is also a dangerous place.

This revolving gate pass is actually where the legendary Tiger Prison Pass (Bishui Pass) is located, and the three British battles in the Romance of the Three Kingdoms happened here, but there seems to have been no war here in real history.

In real history, the so-called eighteenth route princes fought against Dong, but in fact, there was only an eleventh route army, and it was also divided into three route legions.

This Southern Route Army is the conquest army led by Yuan Shu as mentioned earlier, which includes Sun Jian's army and the army of Yuzhou Thorn Shi Kong Ling, who occupied Yingchuan at that time, the Northern Route Army is a tripartite alliance of Yuan Shao, Wang Kuang, and Han Fu, and the Middle Route Army is the combined army of Liu Dai, Zhang Miao, Zhang Chao, Qiao Mao, Yuan Yi, Bao Xin, and Cao Cao and others gathered in Suojube.

In fact, at that time, the middle route army, that is, Cao Cao and Zhang Miao led their troops to attack in the direction of Luoyang, but before they could reach the so-called Tiger Prison Pass, they encountered the army led by Dong Zhuo's general Xu Rong between Xingyang and Bishui, and Cao Cao was defeated and almost died.

In fact, it is doubtful whether Liu Bei took Guan Yu and Zhang Fei to participate in this battle against Dong, anyway, there is really no Sanying Battle against Lu Bu in history.

Of course, the current side of the Tiger Prison Pass may not be the main direction of attack of Cao Cao and Yuan Shao, unless the two armies of Cao Cao and Yuan Shao are united, that is, the Guandu in the original history will march to Luoyang in one place, and it is possible to hit the Tiger Prison Pass.

Therefore, in this direction, Zhu Wei only sent a team of soldiers and horses to garrison the Tiger Pass for the time being, but Zhu Wei still felt that Yuan Shao and Cao Cao were unlikely to join forces together, just in case.

There are two passes left, Mengjin and Xiaopingjin, and you can know by looking at their names that they are located at the crossing of the Yellow River.

Mengjin Pass, also known as Heyang Pass, is an important ferry port on the Yellow River in the north of Luoyang, it is the important Jin in the north of Luoyang in the past dynasties, it is the place where soldiers must fight, as for Xiaopingjin Pass, it is also a Jindu on the Yellow River, the status is second only to Mengjin Ferry, as long as these two ferries are held, Yuan Shao's troops can only stop in the north of the Yellow River.

It can be said that in this defensive battle of Luoyang, Zhu Wei's focus was to build and strengthen the five towns of Dagu Pass, Guangcheng Pass, Yuyuan Pass, Mengjin, and Xiaopingjin, as long as Zhu Wei could block these five places, he would be able to block the army of Cao Cao and Yuan Shao on the periphery of Luoyang......
