Liu Chan nodded and said, "Yes, although there is no danger in Guanzhong now, it is also necessary to prevent the Wei army from sending reinforcements from other places."

Therefore, the top priority at the moment was not to attack Chang'an, but to lead troops to seize important passes and prevent the Wei army from sending additional troops and horses from other places. ”

Hearing this, Ma Chao came out and said, "Your Majesty, Weichen used to be in Guanzhong, and he also has some understanding of the terrain in Guanzhong. To the north of Guanzhong, it was originally the northern land of Liangzhou and the upper county of Liangzhou, but it was gradually eroded by the Hu people in recent years, and the territory of Bingzhou has been greatly reduced.

In the past, the soldiers and horses of the state could enter Guanzhong directly from Shangjun, but now they can't. Now, if the Wei army sends reinforcements to Guanzhong from other places, there are only two ways to go. ”

The territory of the Eastern Han Dynasty was very different from that of the Three Kingdoms, of course, this does not refer to the difference between the three parts of the world, but to the reduction of territory.

Shu and Wu were fine, and they even expanded their territory, while the north occupied by Wei had a great shrinkage compared with the Eastern Han Dynasty.

The most significant changes are the merger of states and Liangzhou.

During the Eastern Han Dynasty, the territory was very large, including several counties of Hetao, as well as Yanmen, Taiyuan, Shangdang, Xihe, Shangjun and so on. Its territory is so large that it can enter the top five states of Dahan.

As we all know, the Yellow River flows through Bingzhou and forms a zigzag in Bingzhou, which was completely included in the Bingzhou in the Eastern Han Dynasty.

Nowadays, the territory of Bingzhou has shrunk by half, not only the Hetao has been lost, but also the upper county in the west is gone, only the lower right half of the zigzag remains, and there are only a few counties around the Taihang Mountain.

The former Bingzhou intersected with Liangzhou, and the upper county of Bingzhou, Shuofang County, was connected to the north of Liangzhou, wrapping the land of Guanzhong, and was the barrier of the northern part of Guanzhong.

And now, the upper county of Bingzhou, Shuofang is occupied by the Hu people, and the Beidi County of Liangzhou has also shrunk greatly, and the northern part of Guanzhong is exposed to the Hu people's soldiers, and there is no barrier.

Therefore, if Bingzhou wants to send troops to Guanzhong, it needs to go south from Shangdang to Luoyang, and then pass through Tongguan from Luoyang to the west. You can't go directly to Guanzhong from the south of Shangjun.

"Aiqing and I will talk." Liu Chan said to Ma Chao.

"No!" Ma Chao gave up his hand, came to the map, pointed to the map and said: "If the Wei army sends reinforcements over, only the Central Plains, Bingzhou, Nanyang soldiers and horses are the closest, and the soldiers and horses of Bingzhou and the Central Plains have to come from Tongguan."

It's just that Tongguan is in the rear of Chang'an, Cao Rui came from Luoyang, and Tongguan must set up heavy troops, so Tongguan cannot be captured before Chang'an, and we are powerless to stop the reinforcements from the Central Plains and the state.

And Jingzhou Nanyang is also adjacent to Guanzhong, and there is a road to communicate, this is Wuguan, Wuguan is located in the southeast corner of Jingzhaoyin, and Wuguan is Nanyang.

Weichen suggested that His Majesty could send troops to take Wuguan, and taking Wuguan could not only block the arrival of Nanyang's reinforcements, but also another way to attack Nanyang in the future.

Because out of Wuguan, that is, the north of Nanyang, you can bypass the fortress of Fancheng, and attack Nanyang in the future, Xiangyang and Wuguan will send troops at the same time, and it will be easy to conquer Fancheng.

Wuguan is not as good as Tongguan, there should be no heavy army garrison, so you can send a force of soldiers and horses to seize Wuguan. Wuguan is a precipitous place, easy to defend and difficult to attack, after seizing Wuguan, send three to five thousand people to defend Wuguan.

Moreover, Wuguan is located in the southeast direction of Chang'an, and it can reach the rear of Chang'an to the north, Chang'an cannot be taken in a short time, and our army will be in a stalemate with the Wei army. ”

Liu Chan listened to Ma Chao's words, walked to the map, looked at it for a while and said: "Yes, this Wuguan is located in the mountains, extremely steep, it should indeed be taken down by surprise first, otherwise when the Wei army reacts, send heavy troops to control the Wuguan, I can't conquer it even with 100,000 troops."

At that time, even if I take Guanzhong, Wuguan can continue to hold on to it with the supply of Nanyang, become a barrier to Nanyang, and threaten the safety of Guanzhong at any time.

After I attacked Guanzhong this time, I was preparing to move the capital to Chang'an after taking Chang'an, and if Wuguan was in the hands of the Wei army, the capital of Chang'an would be threatened at all times. ”

In fact, not only Wuguan, but also Tongguan, if Liu Chan wants to move the capital to Chang'an, Wuguan and Tongguan must be controlled in his hands.

Tongguan is connected with the Central Plains, Wuguan connects Nanyang, these two passes are in the hands of the Wei army, if Liu Chan determines the capital of Chang'an, the Wei army can send troops at any time to threaten the safety of Chang'an.

If these two passes are in the hands of the Han army, Liu Chan can turn the passive into the active, go out of the Wu Pass, attack Nanyang, and go out of the Tong Pass, and then threaten Luoyang, the capital of Wei.

It's just that Tongguan connects the east and west capitals of Wei, and Cao Rui is currently in Chang'an, so Tongguan must have heavy troops and cannot be conquered for the time being. Therefore, we can only take the martial arts pass first.

Liu Chan said, "Who is willing to seize the Wuguan with me, Aiqing?" ”

Hearing this, Guan Yu arched his hand: "Your Majesty, Weichen is willing to lead the army to seize Wuguan." ”

Zhang Fei also surrendered his hand to fight: "The last general is also willing to go!" ”

"Your Majesty, the last general is willing to go!"

"Your Majesty......"

Liu Chan looked at the generals, and said in a deep voice: "This matter will be handed over to Pang De, Huang Xu is responsible, and I will order you two to ......."

When Guan Yu heard this, he was immediately unhappy, and arched his hand: "Your Majesty, the last general has asked for war several times, but Your Majesty just didn't allow it, don't you dislike the last general?" ”

"Why did the second uncle say this?" Liu Chan said with a smile: "The second uncle is proficient in the art of war, I just want to keep the second uncle by my side and listen to the teachings at all times." ”

"Your Majesty is proficient in the art of war, and the use of soldiers is more spicy than that of Weichen, where do you need the teachings of the last general, since the last general went out with His Majesty to conquer Guanzhong, he has not made an inch, so let the last general go to seize the Wuguan."

Liu Chan couldn't refuse, and said: "Since this is the case, let the second uncle go, Pang De, Huang Xu is the deputy general." Leading 5,000 cavalry and seizing Wuguan, without further ado, the Wei army will arrange heavy troops in Wuguan, and the soldiers and horses in the army can be ordered to hurry up to make dry food for ten days. ”

Liu Chan paused and said: "Second uncle, Wuguan is a dangerous pass in the world, and its steepness is not inferior to the Sword Pavilion and Jiameng Pass, so it can only be outwitted, not attacked."

I will only give you ten days of dry food, and it will take eight days to travel to and from this place, so I only have two days to capture Wuguan, and if you can't capture it within two days, you will return immediately. ”

It's not that Liu Chan doesn't give Guan Yu more dry food, mainly because Wuguan is too steep, even if there are only a few hundred people in Wuguan, as long as the defenders are on guard, they can't take it, so they can only use stratagems.

And there is only one chance, if one blow is missed, it will give Guan Yu 50,000 soldiers and horses, and the grain and grass will not be able to be defeated in a hundred days.

Fa Zheng stroked his beard and smiled: "General, I'll give you an idea." ”

Hearing this, Guan Yu asked, "Oh? I don't know what the trick of filial piety is? ”

Fa Zheng said: "Yesterday, our army defeated 30,000 Wei troops, and obtained countless armor and weapons, and the general can bring some Wei army armor over, pretending to be Wei army, and falsely claiming that the Wei army came to reinforce, so as to open the door by fraud." ”

"Good!" Guan Yu laughed when he heard this: "Filial piety is a clever plan." With this strategy, why worry about the martial arts? ”
