However, from the serious expressions of the former military captain, Shi Zhuan could already see that the situation in Ziwu Valley is not very optimistic. After all, if you walk too much, you can call it a road. Ziwu Road has been rarely visited for a long time and few people pass by it, so it is reasonable that the valley road is abandoned.

Wei Yan had planned to march from Ziwu Road to attack Chang'an, but this plan did not obtain Zhuge Liang's consent and eventually aborted. The Shu army's countless northern expeditions never passed by here.

However, the Wei State had an experience of using troops from Ziwu Valley. After Zhuge Liang's two northern expeditions, the Wei State felt a little face-breaking, so he mobilized a large army to attack Shu. Among them, the commander-in-chief Cao Zhen led the army to advance from Ziwu Valley. But he was halfway through the heavy rain. It took Cao Zhen a month to walk less than half of the way. In the end, the troops were exhausted and the food was exhausted, so he had to retreat.

Now that the Wei army attacked Shu, it has been thirty years since the last attack on Shu. Even the plank road that Cao Zhen repaired back then is already in great decay.

The former military captain told Shizhan that the plank roads in Ziwu Valley were mostly damaged. If the army wanted to pass, they had to build the plank roads first.

"What are you waiting for? Hurry up and repair it!" Shi Zhuan said with displeasure. This vanguard has been sent to Ziwu Valley for some time, but it has not repaired all the damaged plank roads yet. How much trouble will it take?

The former military captain also looked helpless. In fact, after being ordered to station in Ziwu Valley, he had already seized the time to repair the damaged plank roads.

However, repairing a plank road is different from other roads. The so-called plank road is actually a hole that is chiseled on the top of the cliff, then inserted into the hole with wooden stakes, connected horizontally and vertically, and then laid wooden boards on it, so that people can pass through.

Some plank roads are shorter, only about one and a half miles away, while others are longer, stretching for dozens of miles, surrounded by mountains and waters, hanging on the side of the cliffs, and the scene is also spectacular.

The plank road is a unique product of the ancient Qinling road and an embodiment of the great wisdom of the working people in ancient times. Such cliffs were originally no way out. The hardworking and intelligent ancient Qin and Shu people dug out the plank road on this cliff, turning the natural barrier into a thoroughfare. The story of Han Xin's openly repairing the plank road and secretly traveling to Chen Cang is well-known and well-known to everyone.

The plank road in Ziwu Valley has been seriously damaged due to disrepair. Thinking about the last time the Wei army marched from Ziwu Road, it was thirty years ago. The plank road rebuilt for the sake of marching at that time has become unrecognizable after 30 years of erosion by wind and rain. Many sections of road have long collapsed and are simply inaccessible.

The former military lieutenant has tried his best to send people to repair the plank road, but the plank road in Ziwu Valley has been seriously damaged and the project volume is relatively huge. Building the plank road is obviously a relatively difficult technical job. No matter how many people are, it is difficult to implement it. The wood required is also a huge amount, so the progress is relatively slow.

When Shi Zhuan heard this, his face suddenly became gloomy. He was originally expecting that the vanguard troops could open roads and build bridges across mountains and rivers, but now even the minimum plank road has not been repaired, and he still wants to compete for the first place with other troops. What a f*ck!

Although there is no hope for the first place, Shizun cannot fall behind too much. You should know that when the mission was over, many people were competing with him for the route of Ziwu Valley. Everyone thought that Shizun, as a new general, had no way to lead the camp out of Ziwu Valley.

Although Deng Ai's support was enough to suppress the generals, it was obvious that the generals were still obviously dissatisfied, believing that Shi Zhuan's ability was not enough to lead the first battalion alone.

The contempt of the generals made Shi Zhuan secretly hold his breath in his heart. They were watching people in the cracks of the door and looked down on them. Of course, Shi Zhuan was not convinced. He must prove it to other generals. He not only could step out of the Ziwu Road, but also won the first merit of Hanzhong, and would never fall into the hands of other generals.

Due to the difficulties and difficulties of the Qinling Road, other troops abandoned heavy equipment and used light-fitting methods when marching. As for large-scale weapons such as catapults, siege cars, crossbows, they can only find ways to transport them slowly in the future. Now soldiers are very fast. In order to arrive at the front line as soon as possible to start fighting, the best way is to light-fitting and simple access, so that they can go twice the way.

However, Shi Zhuan did not choose to wear all lightweight equipment, but brought fifty catapults, because Shi Zhuan knew that after entering the Hanzhong Plain, the opponent facing the camp was the royal house that was huddled in Lecheng. Lecheng, as a fortress city in eastern central and central Han, had very strong defenses. It was not easy to capture Lecheng by relying solely on the tactics of the sea of ​​people alone.

So if you want to attack the city, you have to rely on a powerful siege tool like a casting cart. The camp was equipped with a hundred casting carts, which was obviously unrealistic to bring them all. Shi Zhuan gritted his teeth and only brought fifty cars. As for the stone bullets, the thing was really heavy. Shi Zhuan simply gave up and only brought dozens of stone masons. Anyway, Hanzhong is full of mountains and there will be no shortage of stones. When it comes to using the casting cart, it is not too late to make stone bullets on site.

However, with the size of the catapult cart, mules and horses still need to be pulled. With the passage conditions of Ziwu Valley, these catapult carts are simply inaccessible. Shizun ordered all the fifty catapult carts to be dismantled and broken into pieces, so that they are convenient to carry.

Although it is more troublesome to disassemble and assemble once, in order to ensure that these catapults can follow the troops to Hanzhong smoothly, this is probably the only way. After all, the road in Ziwu Valley can be called a devil's journey, and it is very difficult to pass alone, let alone bear so many loads.

However, in order to ensure that the trap camp has sufficient attack power and not be passive in the siege battle, Shizun tried every means to bring these catapults with him.

The plank road is now slowly repairing, which makes Shi Zhuan worry. He ordered the whole army to take action together to cut down trees nearby and make wooden stakes and boards needed to repair the plank road to ensure sufficient materials.

In terms of repairs, more manpower has been invested, and repairs are carried out day and night, and they are constantly being repaired.

Fortunately, the damaged plank roads were just three or two miles long, not tens of miles long. After several days and nights of repairs by the Wei army, these plank roads were finally repaired. The large army of the camp marched deeper into the Qinling Mountains through the plank road, winding all the way, and the entire team was like a long snake, winding among the valleys and ridges, stretching for dozens of miles.
