Liu Yu frowned slightly and said, "Do you want to turn this incident into a diplomatic operation?"
Wang Miaoyin said calmly: "Don't you want to conquer Hou Qin and regain Chang'an in the future?"
Liu Yu said thoughtfully: "Of course I have. I think about it every day when I sleep and dream. But what does this have to do with sending a child like Sima Xiuxi to Qiuchi?"
Wang Miaoyin sighed: "The so-called first is to attack the enemy, then to attack the enemy, and then to attack the army. You have always been attacking the army, but rarely think about the enemy and the enemy. Brother Yu, if you want to attack Chang'an later,
, then you have to consider which direction to attack from."
Liu Yu smiled slightly: "If you want to capture Chang'an, you usually have to go northwest from the Nanyang Basin, exit Wuguan, and enter Guanzhong. However, this road is not easy to walk. The roads along the way are extremely inconvenient. There is a lack of supplies. Even if Wuguan is broken,
, entering Guanzhong, it is easy to be blocked in the Qingni and Lantian areas. Back then, the Chu State launched an overwhelming army to attack Qin, and they took this road. Unfortunately, after passing Wuguan, the Qin army was blocked in the Lantian area.
It could no longer move forward, and finally failed. Although Liu Bang of the Han Dynasty took this path to conquer the world, at that time the Qin people had lost all their hearts and there were no soldiers available in the pass, so it cannot be regarded as a regular practice."
Wang Miaoyin smiled slightly: "Continue, brother Yu, you are an expert in military affairs, but I don't understand much."
Liu Yu nodded and continued: "If you enter Guanzhong from Guandong from the other direction, there are two passages. One is from Bingzhou, crossing Longmen Ferry to the west, crossing the Yellow River, and entering the Feng Yi area of Guanzhong.
It was the Hexi area during the Warring States Period, so we could directly attack Chang'an."
At this point, Liu Yu frowned slightly: "It's just that the Yellow River's current is very strong at Longmen Ferry. It's not easy to force the army to enter Guanzhong. Once there is defense in Guanzhong, send a large army to garrison on the river bank, or
Deliberately retreat, let part of your army or the front army go ashore, and then find a way to cut off the follow-up. The troops crossing the river will be equivalent to getting into the enemy's siege and falling into death. When the Later Qin Dynasty fought against the Northern Wei Dynasty, Chaibi
In the battle, 40,000 troops were sent from Guanzhong to cross the river and enter Bingzhou from the Longmen area. They also used this siege method for the Wei army to annihilate them all. It would be very dangerous for supplies to rely entirely on pontoons or waterways on the river.
thing."
Wang Miaoyin nodded: "But after the Northern Wei Dynasty's great victory, they did not take the opportunity to attack Guanzhong. It was the same consideration. It is easy to defend but difficult to attack?!"
Liu Yu smiled slightly: "It is not easy to attack Guanzhong, especially from the direction of Bingzhou. If you think about how powerful the Jin State was in the Spring and Autumn Period, it had no choice but to face the Qin State in Guanzhong, and could only think of following Han.
The breakthrough in the direction of Guguan, that is, it took a military god like Wu Qi to strengthen Hexi, and it took more than seventy battles to gain a foothold. Isn't this the best proof?"
Wang Miaoyin said seriously: "Since Longmen Ferry and the Hexi direction are not good breakthrough points, then the only option left to fight from Guandong to Guanzhong is Tongguan Road."
Liu Yu nodded and took a deep breath: "Yes, it is almost the only choice. Since the Hangu Pass Road was abandoned and impassable at the end of the Warring States Period, Cao Cao asked Xu Xu to open up the 800-mile Tong Pass Road.
It has become the best and almost the only option to enter the customs. Generally speaking, from the Central Plains, you can use Luoyang as the frontline base, go north across the Yellow River, enter the southwestern region of Shanxi, and then occupy Puban, which is across the Yellow River.
, that is, Tongguan, which happens to be in a section of the Yellow River that runs from north to south and then turns east. Because it is at a turning point, the speed of the Yellow River water is the slowest in this section. There is even water on the Yellow River between Puban and Tongguan.
There is an island in the middle of the river made of accumulated sand."
Wang Miaoyin laughed: "On this island in the middle of the river, there is a pontoon bridge strung with iron cables. It can pass a large number of troops and baggage directly from Puban to Tongguan. This is also the main channel starting from Guanzhong and entering Guandong.
What I said is right."
Liu Yu smiled and said: "Although Miaoyin has never been to this place, you are familiar with the terrain of the world and the dangerous fortresses. What you said is really good. Therefore, if we want to attack Guanzhong from Guandong, it is best to attack Tongguan with a large army, and
If you use partial troops to leave Wuguan and occupy the entire Bingzhou, you can also use one partial division to cross the river in the Longmendu area to feint attack. If all three divisions attack together, the Qin army in Guanzhong will be able to focus on one thing and miss the other!"
In Wang Miaoyin's beautiful eyes, the water flowed, and she looked at Liu Yu: "Apart from these three directions, is there no other way?"
Liu Yu instinctively wanted to shake his head, but suddenly his eyes lit up: "You mean, you mean the story of Zhuge Liang, the prime minister of the Shu Han Dynasty during the Three Kingdoms period at the end of the Han Dynasty, from the direction of Shu, to the Northern Expedition to Guanzhong?"
Wang Miaoyin nodded: "Not only Zhuge Liang, but also Liu Bang's first step in conquering the world was to build a plank road openly, cross Chencang secretly, and first control Hanzhong from Shu, and then go out of Qishan, take Longyou and Hexi, and even take Guanzhong directly.
ah."
Liu Yu laughed: "Zhuge Liang did not succeed in the Northern Expedition to Guanzhong. It was because the road to Shu was difficult and it was difficult to reach the sky. Even if he could win the land battle, it would be difficult to fight for a long time in Guanzhong due to insufficient military supplies. Therefore, in the end he still
………”
Speaking of this, Liu Yu suddenly thought of something and fell into deep thought.
Wang Miaoyin smiled slightly: "Brother Yu must have realized it. It is really difficult to transport grain directly from Shu to Guanzhong. The road is long and difficult to walk, so every time Zhuge Liang cannot last more than a few months in Guanzhong.
, we have to withdraw our troops. But if on the other hand, the problem of military food supply is solved, then whether it is Liu Bang, Zhuge Liang, or even Murong Chong of Xiyan, won't they all succeed in gaining a foothold in Guanzhong, and can they almost be declared successful?"
Liu Yu laughed: "Liu Bang's success was because he quickly defeated Zhang Han. Zhuge Liang's success was because he was stationed in Guanzhong and supported war with war. As for Murong Chong, it was because he laid siege for a long time.
Chang'an, for two years, slowly changed from weak to strong, from few to many, and finally all the forts in Guanzhong had to switch from supporting Fu Jian to supporting him. So..."
Having said this, he took a deep breath: "Miaoyin, what you mean is that I want to make friends with Yang Sheng by sending Sima Xiuxi this time, so that he can also be with me when our army sends troops to Guanzhong.
Our army joins a joint operation and sends troops to Guanzhong to provide us with logistical supplies to help us take Chang'an directly like Zhuge Liang?! Or we can go north from Qiuchi, pass through Hehuang and enter Longyou and Hexi, capture Liangzhou and cut off the right of Chang'an.
Arm, right?"
