"Please also ask Gongjin to teach the guard!"

Zhu Wei could only patiently ask Zhou Yu for advice, Zhu Wei believed that with Zhou Yu's more than 100 intelligence attributes, he would never say such a suggestion for no reason, so Zhou Yu must be justified in saying this.

Zhou Yu stood up from his seat, then walked to the sketch of the mountain and river sand table on the ground structure in the center of the hall, reached out and picked up a long whip that pointed at it, and pointed at the land of Guanzhong and Xudu.

"Lord, everyone, look at it, when Cao Cao occupies part of Gunzhou and Yuzhou, and Guanzhong is also attached to the name of the Son of Heaven controlled by Cao Cao, there is Yuan Shao in the north, and there is Wu Fang in the south, this Cao Cao lives in the Central Plains It can be said that it is difficult to defend in four wars! If I am Cao Cao, I must be unwilling to be coerced, but Yuan Shao and I are not easy to beat, so how can we get out of the predicament? Only about the middle also! ”

Zhou Yu paused when he said this, but his words also made everyone here look moved, even Zhuge Liang, who was in charge of recording on the side of Zhu Wei, had his eyes flickering a few times.

"In the past, the tyrannical Qin lived in Guanzhong and sought the world, and now Cao Cao can only survive by jumping out of the Jedi, so Guanzhong is his best way out! Although it is necessary to abandon the old land of Gunzhou, it can finally avoid the threat of the south and the north! And there is a big city of Luoyang in the pass, and there is Hangu Pass as the gateway, Cao Cao only needs to guard Luoyang, and use Hangu Pass to guard the hinterland of the imperial pass, so that he can accumulate strength in the pass, and wait for the dispute between the Central Plains and Yuan Shao! ”

"The lord thinks about it, if we attack Cao Cao, Cao Cao coerces the Son of Heaven to flee into Guanzhong, or uses Gongzhou to offer Yuan Shao to ask Yuan Shao for help, then we and Yuan Shao will fight for the benefit of the Central Plains, and the two strong fights, and there is indeed no time to take care of Cao Cao, but Cao Cao can take the opportunity to develop in Guanzhong, and I am afraid that it will be a big disaster in the future!"

"And now, Guanzhong is still empty, Cao Cao's soldiers and horses are guarded in the land of Xudu and Gunzhou, although there is Si Li's lieutenant Zhong Xuan sitting in Luoyang, but Zhong Xuan's account is just Wu Xi, Duan Xuan's two Xiliang remnants! That section of the simmering army is only a few thousand guarding Hongnong, Wu Xi is only three or five thousand guarding Luoyang, and the rest are in Chang'an or Ma Teng, Han Sui and other departments, but they are not enough to resist our army! Therefore, if our army goes out of Wancheng and takes Luoyang, and then captures the counties of Guanzhong, we can get the land of Guanzhong, and we can also cut off Cao Cao's retreat. If you attack Cao Cao again like this, you will teach him nowhere to escape! ”

Zhou Yu pointed to the Guanzhong Silizhou County area, which also paid special attention to some garrison places, but the most critical statement really made Zhu Wei nod.

It turns out that Zhou Yu's current strategic arrangement, although it seems to be similar to Wang Yuyan's strategy at the beginning, the specific purpose is completely different.

Now it is a strategic offensive strategy, in order to prevent Cao Cao from retreating to Guanzhong in the future, and preemptively seal Cao Cao's retreat, so if Zhu Wei launches a war against Cao Cao, Cao Cao can only meet it, and there is no possibility of dodging.

Unless he threw himself directly at Yuan Shao, but even then he still needed to face Zhu Wei's offensive, even if Yuan Shao sent troops to help, he could not avoid Cao Cao's downfall, and Cao Cao didn't want to hide to the side.

"Well, I see, this matter is also feasible, but if our army is tackling the key problems, how will Cao Cao deal with it?"

Zhu Wei saw that many people in the hall also began to agree with the strategy proposed by Zhou Yu, so he continued to ask, after all, Cao Cao is not a fool, once Zhu Wei sends troops to Guanzhong, then Cao Cao will definitely not watch it.

"It depends on the speed of our army, if our army starts from Wancheng and rushes to attack Luoyang, now Guangcheng Pass is deserted, so our army only needs to break through the Dagu Pass, so Cao Cao can not respond! After that, you can send a large army to Luoyang to resist Cao Cao, so that Cao Cao can no longer enter the pass! If Cao Cao refuses to give up, the lord can send a partial division to take the Guanzhong lands, and then counterattack Cao Cao with the main force, so that it will be more justified! ”

Naturally, Zhou Yu could not be completely sure of the development of the future war, but if he sent troops from Nanyang to attack Luoyang now, it would indeed be a normal offensive route.

When the Eighteenth Route Princes Alliance was fighting against Dong, Yuan Shu was stationed in Nanyang in response to Dong's call and was ready to send troops to attack Luoyang.

Then Sun Jian, the main force of the Dong army along the way, was called all the way north in Changsha County, and first used a trick to trap Wang Rui, the assassin of Jingzhou, and Zhang Shi, the Taishou of Nanyang, and strengthened his own capital, and then with the support of Yuan Shu, he was shown as a general who broke the captives and led the history of the assassination of Yuzhou, and assumed the great task of attacking Luoyang where Dong Zhuo was located in the north.

It can be said that Sun Jian took advantage of this opportunity to develop his power, and he first used a method similar to the empty city plan in Luyang to scare off Dong Zhuo's tens of thousands of cavalry, which is also the real source of the Three Kingdoms empty city plan.

Next, Sun Jian seems to have suffered a setback near Dongguangchengguan in Liang County, but looking at historical records, it should be that Sun Jian took a small number of soldiers and horses to observe Dong Zhuo's military situation, and encountered Dong Zhuo's army led by Xu Rong to come out and plunder the place, but Xu Rong discovered Sun Jian's traces, and naturally he was excited to lead the troops to chase and kill.

At that time, Sun Jian relied on the sacrifice of his general, Zu Mao Li Dai Taozhuang, to escape with more than a dozen horsemen.

In the second year, Sun Jian reorganized his troops and horses and went north again, this time it was a smooth journey, he first broke the Dong Zhuo army led by Hu Zhen and Lu Bu in the battle of Yangren Pass (Guangcheng Pass), killed Dong Zhuo's general Hua Xiong, and then defeated Dong Zhuo's army again and again, and finally attacked Luoyang City.

Of course, at this time, Dong Zhuo had already burned Luoyang and took Emperor Han Xian to Chang'an, so after Sun Jian picked up the jade seal in the Luoyang Palace, he also withdrew his troops and returned to Nanyang.

Judging from Sun Jian's example of taking Luoyang directly from Nanyang, there is indeed a direct route between Nanyang and Luoyang, and now there is only one pass called Dagu Pass, which is blocked in the south of Luoyang.

This Dagu Pass is an important pass from Luoyang to Nanyang, Ruzhou, Xuchang and other places, and the surrounding area seems to be the mausoleum of the emperors of the Han Dynasty, so in the original history Sun Jian fought to the Dagu Pass, the record is that Dong Zhuo and Sun Jian fought between the tombs of the Han Emperor, and then Dong Zhuo was defeated and went to Michi, and Sun Jian entered Luoyang.

In the Romance of the Three Kingdoms, the story of "Sima Yi designed to earn Cao Shuang" is also related to Dagu Pass, Emperor Cao Fang of Wei left Luoyang to worship the tomb of Emperor Wei Ming, Gaoping Mausoleum, and the Cao Shuang brothers who controlled the government at that time followed, and Sima Yi, who was suppressed by Cao Shuang, took the opportunity to lead troops to Sima Gate, control Luoyang, and forced Cao Shuang to surrender.

Soon after this incident, Cao Shuang was convicted of destroying the three clans, and from then on, Cao Wei's military and political power fell into the hands of Sima Yi, and finally Cao Wei became Sima Jin.

Obviously, the mausoleum of Emperor Wei Ming seems to be where the tombs of the Han Emperor are located in Dagu Pass, so Sima Yi sealed Dagu Pass and let Cao Shuang be locked up outside Luoyang.

Well, these are not much nonsense, just say that now the land of Nanyang in Jingzhou is under Zhu Wei's control, so Zhu Wei can send troops from Wancheng to threaten Xudu, or he can go from Wancheng to Dagu Pass through Luyang and Yangren, as long as he captures Dagu Pass, he can directly face Luoyang City......
