In February of the spring of the tenth year of Wude (34 AD), after the ice and snow melted in the Qinling Mountains, Ren Guang, the Wei Dasi Nong set off from Yongcheng, Yufufeng, and headed west to Chencang, crossed the ancient ferry of the Wei River, went south to Dasan Pass, and crossed the old road to enter Wudu County.

This route is completely opposite to Han Xin's northern expedition to the Three Qins two hundred years ago, and no army has passed it for many years: During the reign of the Lu Hou of the Han Dynasty, the Wudu earthquake not only changed the flow of the Western Han Dynasty, but also caused the nearby landslides and the plank roads to be destroyed. The old path was cut off for several generations and was not renovated until the time of Emperor Wu of Han. However, due to the change of the river, it was no longer suitable for large army to advance.

When the world was split in the Xinmo period, Wudu and Hanzhong were controlled by Gongsun Shu, so at that time, the two emperors of Wei and Shu could only stare across the Qinling Mountains. Both sides went back and forth through Qishan Road, which had water to transport grain, but maintained a fragile peace on the old way. The Fifth Reunion and Gongsun Shu both knew that the old way, which lasted for 800 miles, could only keep the number of people below a thousand people, and sent them to the other side for free.

But when Wudu County was captured by Ma Yuan, the situation was completely different!

When he crossed the Qinling Mountains and arrived at a location called "Huanghuachuan", Ren Guang got off his horse, looked back on the mountain, and praised: "In the past five years, Gongsun Shu, in order to regain Wudu, he ignored the strength of the people in Shu, and sent large troops to fight for him all year round. While His Majesty ordered General Ma to defend, he dispatched 30,000 civilians in Guanzhong to repair the old path. This is how fast the three armies went south today!"

There are stone tablets on the Huanghua River as evidence, but it is the work of Wudu County’s elders praising the fifth reunion and road construction. They still remember a verse: "Only this old way is located on the right side of the Han Dynasty. The stream is floating in the source of the river, and the pillars are crossed on the road. When the autumn rains are drifting, the basin overflows in the wild, the Han River is backwards and stagnates the army."

"Only my holy master is virtuous, handsome, and gentle, and is frugal, and willing to be polite, and is like a god. In February of the sixth year of Wude, the military and civilians built roads and the plank roads were connected to the sky. Even though Lu Ban was in the past, there was no sign of elephant. For a while, people were happy and the people were happy. So I chanted this verse. In the past, Yu led the rivers and stabilized the four seas. Now the Holy Wei agent continued, and Ai Kang ten thousand miles..."

Although there are many praises, the improvement of traffic after the rebuilding of the old road is obvious. Compared with the detour of Longyou, the traffic with Guanzhong was shortened by nearly one month.

In order to make up for the problem of food transport caused by the lack of rivers, the Fifth Lun distributed the mules and donkeys raised in Shanglin area of ​​Guanzhong to Ma Yuan in one breath. These beasts are good at transporting heavy objects in the mountains and wading through mountains and rivers. Shaofu also made a unicycle called "Muqiu Flowing Horse" to carry grain bags. Ren Guang carried them to the front line - before and after the Fifth Lun decided on the "Southward Advance" strategy, the war had already begun!

When a big river: the Western Han River appears in front of you, it means that the front command post of the Wei army in the Battle of Hanzhong: Ju County (now Lueyang County).

Ju County is very small, but Wudu County is an inconspicuous small county town surrounded by mountains. It seems to be surrounded by huge walls that are towering into the clouds, which makes the city light not very good. It is clearly noon, but it still looks dark in the shadows of the mountain. In addition, the surrounding rivers are flowing, and the water vapor is quite abundant. It is said that it is foggy for half a year.

When the Wudu prefect who came to greet Ren Guang met, he looked at the mule and wheelbarrow behind Ren Guang and complained: "The Grand Minister's Estate, the grain can no longer be stored."

Ren Guang has been preparing for logistics for so many years and has been to many places. This is the first time he has heard such an outrageous complaint - ordinary local officials, school lieutenants, and grain officials, they only mutter "hate little" when they see them! Now they still think that there are too many supplies!

But just look at the pitiful Ju County, you will understand: its size is just the size of a town in Guanzhong, just a few streets behind the walls. In order to vacate houses and store grain, people have to move outside the city to set up camp.

"This Ju County is indeed not suitable as a place where the army gathers." Ren Guang also frowned, but Ju County is small and its geographical location is extremely important.

The north of Ju County is naturally the old way when Ren Guang came; to the northwest, you can reach Qiuchi Mountain through the Western Han River, and further north is the Wudu County Mansion where Wei Xiang died, and then you can see the Qishan Mountains and enter Longyou.

Going south to Ju County, you can enter the famous Jinniu Road along the Western Han River, but if you walk more than 300 miles, you will be blocked by a magnificent pass. This is the "Baishui Pass", the leader of the three major passes in Yizhou. Since losing Wudu, Gongsun Shu has been stationed in Baishui Pass for many years, building dangerous passes, and guarding against the Wei army's sneak attacks.

And what about Ju County going east? You can follow the mian water to enter the Hanzhong Basin...

From this we can see that although this place is small, it is well-connected and the most important.

In this way, we can only further transport the grain of Ju County to more advanced areas. This is the reason why the Fifth Reunification sent Ren Hong to coordinate the south.

But Ma Yuan was not seen inside and outside the city. When I asked the prefect of Wudu, I realized that Ma Yuan had left the county the day before yesterday and went east...

"The General of the Cavalry went to Yangping Pass to inspect the enemy situation!"

...

After three days traveling east from Ju County, Ren Guang found that the front could not be reached.

The Hanzhong Basin is a narrow basin sandwiched by the Qinling Mountains and Bashan Mountains, only a hundred miles between the north and south. This area is the narrowest. There are finally thin cracks several miles wide among the undulating mountains, and it is blocked by earthen walls and stone walls. In addition, the flowing Mian River makes it easy to defend but difficult to attack.

This is Yangping Pass, the western gateway of Hanzhong.

Ma Yuan's camp is located west of Yangpingguan, stationed along the Mianshui Valley for several miles. Ren Guang had to walk from the end of the camp to the head of the camp before he saw Ma Yuan on a towering tower.

Ma Yuan was already a latecomer, but after he was established, he met Wuhe and followed him to conquer the world. Now, more than ten years have passed. Ma Yuan, who is 48 years old, has a little white on his hair and beard. He has been fighting for many years and his eyes have become vicissitudes. However, all this does not look old, but instead makes him look more charming.

Ma Yuan was very happy to see Ren Guang arrive. General Ma only captured military affairs, and Ren Guang wanted to prepare for the next civil and political control after conquering Hanzhong. With such a strong and capable assistant, anyone would be happy.

"Boqing, come and see this Yangping Pass."

Ma Yuan handed Ren Guang the Qianli Mile Mile Mile in his hand, and in the extended field of vision, the enemy's virtuality and reality were clearly visible.

The Yangping Pass was filled with flags and a large number of Shu troops were stationed, followed by the base camp of the Shu army in Hanzhong: Mianyang City.

Ma Yuan said beside him: "The mountain range north of Yangping Pass is called Tiandang Mountain, and the mountain south is Dingjun Mountain!"

"Two mountains and one pass, like three screens, firmly protecting the western entrance of Hanzhong, it is worthy of being one of the three passes in Yizhou."

The so-called three passes of Yizhou are Baishui Pass on Jinniu Road, Jiang Pass that guards the Three Gorges, plus the Yangping of Hanzhong.

"This place controls Sichuan and Shu in the south, Qin and Long in the north, and is connected to Jingshan in the back. The army is towering in front, Zhuo Bi, and the white horse, Taurus ox on the right, and the clouds and mist on the left, hundreds of feet, Han, black, and the waters are surrounded by it, which is extremely dangerous in the world. Gongsun Shu got this, and he forced to erode Yong, Liang and expand the land; he could stick to the key points below, as a lasting plan."

Ma Yuan said that there were many praises to Yangping Pass. Ren Guang put down the Qianli Mile Mile Mile Mile and smiled: "Since that's the case, all the ministers in the court thought that they could order the general to lead his troops to go south from Wudu to take Baishui directly, and go to Sichuan to destroy Gongsun Shu. Why did the general report that he should attack Yangping first, and not attack Baishui Pass?"

"The danger of Baishui cannot reach Yangping Pass."

Ma Yuan said: "What's more, even if you seize Baishui Pass, there are two natural dangers behind it. One is Jiameng Pass and the other is Dajian Mountain. The local Lianshan Mountain is completely dangerous and the Feige thoroughfare. After Gongsun Shu lost the Wudu, in addition to sending troops to retake it all year round, he also built a pass between Dajian Mountain, called Jian Pavilion, which can be said to be a man who can pass the pass without tens of thousands of men..."

He shook his head and said, "Although Gongsun Shu is a frog in the well, he is quite stubborn and struggles to get married. Even though he is exhausted, it is still not easy to succeed in one fell swoop."

Gongsun Shu and Ma Yuan are not only from Maoling, but also have similar families. They have been playing together since they were naked. They know this little boy very well. The "residence" given to Gongsun Shuxiu in Chang'an is probably useless.

Ma Yuan pointed to the east: "Yangping Pass is different. Once this pass is taken down, there will be no huge danger in Hanzhong for thousands of miles, just like a hollow bamboo that can be stabbed to the end! What's more, Gongsun Shu has arranged surrendered generals in Hanzhong and divided them into three. Mianyang in the west, and Hanzhong County was established in the south, and Jinghan was stationed; the "Chengxing" County was established in the west city, and the surrendered general Yancen was stationed; the easternmost part of Shangyong, Fangling and other places were established in Shangyong, Shangyong County, which was controlled by Deng Feng and Jia Fu."

Ren Guang immediately understood and added: "The general's intention is that compared to the Bashu directly controlled by Gongsun Shu, the three counties in Hanzhong are in power, and the army is coming, and they will inevitably have their own selfish intentions..."

"In addition, the Taurus Road has been blocked by our army. The transportation between Hanzhong and Chengdu can only be carried out on the Micang Road to Bajun. Our army can currently go through the old road and directly transfer troops and grain from Guanzhong, while the other side will go thousands of miles away, and attack Hanzhong will make the family exhausted and run!"

Ma Yuan nodded: "Isn't this your Majesty's intention?"

"Since you can't destroy Shu in one blow, you can use coyotes to hunt cattle, bite out the wound first, make it bleeding continuously, and finally fall to the ground with exhaustion."

"Wudu County is the first wound, and has been bleeding for more than five years. Now we can go further, aim at the bone joints, and then put the mouth on again!"

Ma Yuan seemed to have seen the ending, so cruel. Gongsun Shu, a small court living in Yizhou, would be destroyed by the fifth reunion in this way. But Ma Yuan thanked the fifth reunion and handed over this matter to himself.

"In the end, I will cut off his throat!"

This is his greatest respect to his old friends!
