The Three Kingdoms began to deceive Liu Bei. Chapter 605, the main text volume: 2.0. The troops in the Guanyu defense zone were 60,000. This time, he took away 40,000. In Wenxi, he left 20,000 elite troops to defend the city in Anyi.

After heading west from Jiangyi County, after two days of march, the troops quietly arrived at Huangfuyi, the source of the water.

Although the journey took only 120 miles and it seemed unfast after walking for two days. But considering that this is already on the edge of the Taihang Mountains, there are many slopes and hills, and valleys and valleys, this speed is already quite rare.

The troops basically walked along the river before supplies were transported along the water by new ship-type schooners.

Among the 40,000 people of Guan Yu, a considerable number of them were his old subordinates when he was pacifying the Qing Tang and Qiang in Xiliang two or three years ago, including young generals such as Wang Ping and Zhang Ren. This team had just been transferred from the west to reinforce in the second half of this year, so they did not participate in the battle of Guan Yu's defeat in Luoyang in the first half of the year, and their combat power was relatively complete.

The reason why Guan Yu didn't use them was that the battle to raid Luoyang in the first half of the year did not use the Qingqiang soldiers, the sole soldiers, Banyan Man and other mountain troops under Wang Ping's command. The route that Guan Yu chose was also south of the Wangwu Mountains, and there was no room for mountain soldiers to operate.

But this time, Zhuge Liang advised him to go further and more dangerously north of Wangwu Mountain. The entire army needed to go deeper into the Taihang Mountains in exchange for the suddenness of the surprise attack. In this case, Wang Ping and Zhang Ren, who had been idle for two years, had a place to use it.

Yuan Shao had no idea how Liu Bei lived those five years!

That is, from the time Dong Zhuo entered Beijing to the destruction of Li Jue, Liu Bei was blocked in the Yizhou valley for five years!

In order to cross the Qinling Mountains, Daba Mountains, Minshan Mountains and Longshan, Liu Bei made many farming arrangements and refined many mountain troops.

Liu Bei's camp once thought that with the goal of "restoring Guanzhong and returning to the old capital", these mountain soldiers could gloriously complete their historical mission. Unexpectedly, after two years of rest, they were pulled back from the edge of the Qilian Mountains in Xiliang, and they had to intersperse another wave in the Taihang Mountains to exert their remaining energy.

Among Guan Yu's 40,000 soldiers, there were a total of 15,000 mountain soldiers, mainly Qingqiang soldiers, accounting for 8,000. Because the Qingtang Qiang people originally lived in Qinghai, the mountainous areas on the border of Sichuan and Tibet, including the Qilian Mountains, and were used to the climate of bitter and cold snow-capped mountains. Therefore, even if they came to Bingzhou to fight in November of the lunar calendar, they still could withstand the cold climate.

The second most are the old soldiers, that is, the Yi people from Daliang Mountain in western Sichuan. These troops are also close to the snow-capped mountains on the border of Sichuan-Tibet, and are not as cold as possible.

The least one is Banyan Man in Wang Ping's hometown, that is, Daba Mountain Mountains in Brazil, with only two thousand people. If it weren't for the commander of the mountain army, Wang Ping had to lead some fellow villagers to enrich the grassroots officers, Banyan Man wouldn't even bring so many because his cold resistance was too poor.

As for the Yishan soldiers from the Southern Barbarian Kunming who provided Ji Han with a considerable number of "Wu Dang Flying Army" sources in history, they were not brought at all this time. These people would freeze to death without fighting when they came. Unless the war was still in the Taihang Mountains until next summer, it would be possible to bring these people to use them.

...

After arriving at Huang's father, the essence of the army's detour in the mountainous area was truly beginning to be reflected.

Wang Ping, Zhang Ren and other generals commanded the soldiers to drag a new type of ship-type schooner that was larger and longer than the original model from the water. They went through a lot of hard work. In the absence of cattle and horse traction, they completely relied on human push and pull to Qinshui thirty miles away. In this short thirty miles, they would drag it all day.

However, after reaching the source of Qinshui tributary, the difference between these caravans and old caravans was truly revealed. After arriving at the destination, the soldiers opened the slings connected to the axle sleeve under the carriage, pushed the carriage into the water again, and the wheels and wheel axles remained on the shore.

It turned out that Huang Yueying's improved carriage has increased the carriage, especially the length, and like a boat, it has also increased the baffle that is easier to stack and waterproof on the side of the ship, and also adjusted the waterline surface at the bottom of the ship.

It is precisely because of these adjustments that this kind of caravan is no longer suitable for long-distance transportation on land. It can only focus on water transportation. It can only take a little while on land, which is very difficult. It is equivalent to using better water transportation airworthiness to exchange for sacrificing land transportation throughput.

But more importantly, the wheels and axles are made in one-time detachable, so after the ship sails to Qinshui, it permanently dismantles the wheels and becomes a ship. The ship can only stay in Qinshui-danshui for the rest of its life and finally flow into the middle and lower reaches of the Yellow River.

Because as long as the caravan has permanent wheels and axles at the bottom, its water-based seaworthiness will definitely be inferior to that of a real ship, and its resistance and fluid stability will decrease. The caravan was originally designed to be used in the northwest and the proportion of mileage and land transportation in the northwest is relatively average.

What caravans fear the most is the undulating terrain of the mountains. Even if they walk on water, they dare not walk through mountain rivers with large drops and unstable water speeds. They are even more afraid that the draft of small rivers in mountain areas will change rapidly. When they pass through dangerous shoals, they will knock the wheels at the bottom of the boat, which will directly lead to the hull being pushed up and disintegrated, and the ship is destroyed and people are killed.

Therefore, when Li Su was in the Northern Expedition of Guanzhong from Yizhou, he only dared to build a wheelbarrow, and he never considered a caravan from beginning to end. The caravan was only dared to take it out when he succeeded in Guanzhong's Northern Expedition of Guanzhong and was in the Great Western Liang Great Gobi Desert.

Now, the wheels are made to be disassembled at one time and after disassembly, they will be permanently turned into ships. This is just to solve the problem that "Liu Bei's camp has not occupied any ports along the basin below the Sanmenxia of the Yellow River, so it is impossible to build ships in the middle and lower reaches of the Yellow River."

The design indicators of a new ship like Huang Yueying are truly permanent ships, not temporary cargoes for both amphibious and land use, and can fully meet the transportation of rivers in mountainous areas. At the same time, they can be built in Guanzhong, drive over by land, and be launched on the Bingzhou side.

Of course, because this kind of ship dismantling wheel can't come back after sailing in mountainous rivers. Therefore, the loading and unloading work that could be saved when transported by a chariot will appear again.

Now it is only the first time I have to carry goods and overturn the mountains. I don’t have to load and unload them. I will come back to pick up the second batch of goods in the future. When fighting a protracted war, I have to arrange many civilians in Huangfuyi to unload the military supplies from the Fen River to the west and load them on the truck. I will take 30 miles east, and then load them on the truck in the Qinshui unloader.

Such loading and unloading workload is also very terrifying. If there are hundreds of thousands of troops on the front line, it will be easy to support tens of thousands of dock workers here all year round.

Fortunately, Zhuge Liang is not a person who is responsible for killing and burying. He traveled with Master Li for a year of "graduation trip". He also took Huang Yueying, who was still his fiancé at the time, and took him to a caravan for more than half a year. He took him more and more personally. He could figure out the pain points every day and come up with some supporting solutions.

Therefore, this time Zhuge Liang provided ideas and Huang Yueying helped implement them, and developed a new type of human pulley-type crane that can be used in dock operations, which is the "squirrel cage crane" in later generations.

At the same time, Zhuge Liang optimized the logistics and ship loading methods of Guan Yujun, made some wooden nails, and piled up food, grass, weapons, and other things in these wooden frames, similar to the wooden frames that shovel goods one by one in modern warehouses.

This wooden frame can be hung directly on a rope hook, lifted with a squirrel cage pulley crane, and then placed on the other end. This can be easily done in one click, lifted from the boat and put it on the car, or lifted from the car and put it on the boat. There is no need to carry bags of grain around.

Not to mention the realization of "container-type efficiency", it is at least "pallet standardization". The labor force of dock loaders and unloaders has been greatly reduced, and the cumbersome operation has been saved by at least 80%. Although the effort spent on carrying goods has not decreased, as long as the operation is cumbersome, it is possible to try to add a transmission mechanism in the future to allow cattle, donkey and other animal power to drag the crane.

As soon as the two logistics plug-ins, "off-site shipbuilding" and "cracking and unloading frame loading and unloading", opened slightly, Guan Yu's army's strategic mobility and durability in the Taihang Mountains naturally broke out a small step. It is not surprising that they took those large-scale deep detour routes that the enemy could not imagine.

...

After struggling in Huangfuyi for two days, a fleet formed out of thin air in the upstream of Qinshui tributary, and a dock was established to leave some troops to defend, Guan Yu's main force continued to advance westward.

Moreover, because his troops were actually operating in the steep and remote places in the Taihang Mountains in the past two days, the enemy did not notice that the Duanshi and Wuze, the nearest county occupied by Yuan Shao's army, were still sixty and eighty miles away respectively.

If you put yourself in your shoes, you can understand that the source location of the rivers in mountainous areas must be in remote and steep mountains, and there is no fertile land to cultivate, so there is not even a place for farmers to live in, and at most some hunters are hunters.

It is already November of the lunar calendar, and it won’t take long before the Taihang Mountains will be closed with heavy snow. Hunters will have already stored the harvest they need to survive the winter. Who would run to such a place?

In contrast, along the way, I encountered a small group of people. After I caught them, I found that they were all remnants of the black bandits who were destroyed a few years ago.

It can be seen that Zhang Yan was killed by Yuan Shao and Lu Bu five years ago. Some of his stubborn and stubborn people drilled into the valley. Five years have passed and they have not been killed by Yuan Shao and have been wiped out. Yuan Shao’s administrative efficiency is really not satisfactory.

However, these black mountain bandits were not in trouble to help their enemy Yuan Shao stand up, so even if they saw Guan Yu's army, they were too lazy to inform him.

On November 13, Guan Yu's army appeared under the two counties of Duan and Wuze, and they all detoured in advance, cut off the Qinshui Road to prevent the officers, soldiers and people in the city from breaking through and reporting.

These two small mountain counties, speaking of the first half of the year, were still under the jurisdiction of Guan Yu because they were from Hedong County in terms of territory. Later, in April, Zhang Liao led his troops to cross Kongcangling and Zhongtiao Mountain to attack Wenxi and Anyi. When he crossed Kongcangling, he occupied the two counties.

Because it was really desolate and could not connect to his core territory, Guan Yu did not consider regaining it until now.

(Note: When Zhang Liao came, he did not consider the food route because Jia Xu was very sure of the success rate of the sneak attack and felt that he would definitely succeed. At that time, information showed that Guan Yu was in Wenxi, Dongyuan and Zhouyangyi hoarded a large amount of military supplies for the troops expeditioning Luoyang. Therefore, as long as Zhang Liao and Jia Xu succeeded in the sneak attack, they could steal Guan Yu's military supplies.

But Guan Yu cannot learn from Zhang Liao now because the Ye Wang is not completely empty, and Tuo Yi is on the defensive position, and there may not be enough food in the Ye Wang city to seize. In addition, both sides of the fight completed the autumn grain storage in winter, and there was no food in the wild. Guan Yu could starve to death without considering logistics. The enemy was also unprepared because he knew that Guan Yu would starve to death.)

At this moment, Guan Yu couldn't wait to temporarily build a siege weapon, so he directly cut wood to make simple flight ladders and hit the door wood, and then launched a fierce siege to try to take down the county town at the source of these two Qinshui tributaries.

In this way, even if the enemy reacts and counterattacks in the future, they will be blocked by these two counties and cannot reverse the logistics port area of ​​Jiangyi and Huangfu, and it will not be possible to threaten Guan Yu's small section of grain roads on land.

As for the food routes that are purely waterways from Duan and Wuze to the south, Guan Yu was not worried about being threatened by Zhang Liao in the future. Because he used a real shipping this time, not a simple 1.0 version of the chariot. Moreover, the flow and depth of Qinshui were also increased further when he went south.

Zhang Liao's cavalry came over Kongcangling and it was difficult to intercept the river in the mountains. The enemy had no ships in this section, so they could only shoot at the cavalry and transport ships. No matter how they looked, the cavalry suffered a loss.

Less nonsense, the Duan and the siege of the city began soon, and Wang Ping and Zhang Ren led the mountain soldiers who were good at climbing to attack one city.

The local Bingzhou soldiers had never seen the climbing tactics of the southern mountain soldiers, and did not understand the characteristics of these enemies, so they were shocked.

Of course, Bingzhou is also a place with strong people. If a soldier from a black bandit defends the city, it is also a match for such a chess-like climb to the enemy.

Unfortunately, these two counties are too small and there are not many elite soldiers from Zhang Liao who are guarding them. The local commander's armed forces are not enough. In addition, Zhang Liao has not had any effort to clear the place in the past six months, and many soldiers have surrendered from Guan Yu. Just before April this year, they still followed Guan Yu.

Now that the main player has returned, the momentum is still so fierce. The Duan and Wuze counties were recaptured in just one hour.

Guan Yu knew that Zhang Ren was good at guarding, so he asked Zhang Ren to lead five thousand mountain soldiers and thousands of crossbowmen to guard the two mountainous counties on the Qinshui shores, protect the grain roads, and resist the possibility of Zhang Liao's side attack and interception within a few days.

Guan Yu himself led the remaining 30,000 people, Xu Huang, Wang Ping and others, and continued to go south along Qinshui.

Next, there are still 180 miles away from the final destination Yewang County.

The main obstacle along the way is a Shimen Xing at the entrance of the Taihang Valley, plus a Qinshui County, and then you will arrive.

Qinshui County is not a dangerous place, it can be ignored, and it can even be driven directly from the river outside the city.
