Li Yan listened to Zhuge Liang's words, his face was surprised, and he immediately shook his head and said: "I don't know about this Pang De, but despite this. Our army is from Jiange to Yangping Pass, thousands of miles away, and it is a dangerous road with mountains and rivers, and it is difficult to run with soldiers and horses, grain and grass.

What if our army delayed the deadline and Xiahou Yuan captured Yangping Pass before our army sent troops? Now, even if our army successfully reaches Yangping Pass, if we can't defeat Xiahou Yuan in a short time, and then the stalemate will last for a long time, and the grain and grass can't be maintained, what should we do?

This plan is too risky, I think the lord should lead all his troops from Bazhong, concentrate superior forces to fight Cao Cao's main force, if Cao Cao can be defeated, then Xiahou Yuan's partial division is not enough. Moreover, the military adviser generally does not seek victory in stability, why is this conspiracy offered today? ”

As soon as Li Yan's words came out, everyone nodded in agreement, except for Fa Zheng.

Zhuge Liang shook his head and smiled: "What the positive side is worried about is the problem that Xiahou Yuan and his people and grain and grass are difficult to transport.

As for Xiahou Yuan, I have already said in advance that this person only has the courage of a horseman, and most of the soldiers and horses are the elite of Xiliang, and he cannot give full play to his advantages in the area of Yangpingguan in Wudu. Conquering the city is not a strong point, and as long as Pang De guards Yangping Pass, he does not have to worry about Yangping Pass being captured by Xiahou Yuan.

As for the grain and grass, I have always liked to study some of the art of the mechanism, when I was in Jingzhou, I was inspired by the prince, and the prince studied a kind of car together, this car can be used for mountain transportation, only one person is needed, no need for cattle to pull the horse, extremely light, after entering the Sichuan has been successfully developed, can solve the problem of grain and grass transportation.

As for my style, the positive side is wrong, although I act steadily, I don't like to take risks, but the soldiers out of Yangpingguan, but not risky, but have the certainty of victory, I suggest that the lord do this, this is strange, not risky! ”

Hearing this, Liu Chan, who was sitting next to Liu Bei, smiled faintly.

Most of the people of later generations felt that Zhuge Liang had a steady style of using soldiers and did not like to take risks, but they were wrong.

This statement is mainly related to Wei Yan's Meridian Valley conspiracy.

Zhuge Liang's refusal of Wei Yanbing's suggestion to go out of Meridian Valley made the world think that he was too steady in using troops and did not like to take risks.

However, an excellent commander will not be in danger when using troops, they will judge the situation and consider the feasibility of each step of the strategy. Every step is taken through precise calculations.

And the conspiracy, although strange but hidden strange, although strange and dangerous, but there is a certainty of victory, no general, will use uncertain tricks and dangerous schemes.

And the Northern Expedition is in danger, once it fails, Shu Han will be destroyed, it can be seen that Zhuge Liang has been taking risks all his life, but although he is in danger, Zhuge Liang is sure that even if he does not win, he will not be defeated, this is Qizheng.

As for the wooden ox and flowing horse, it was quite famous in later generations, and basically anyone who knew a little bit of knowledge had heard of it.

However, this wooden ox and flowing horse was only studied by Zhuge Liang in the later period of the Northern Expedition, and Liu Chan thought of this when he had nothing to do in Jingzhou before, so he studied it with Zhuge Liang.

The wooden cow flowing horse is extremely well-known in later generations, and even many people have studied him, Liu Chan is quite fond of the Three Kingdoms, so Liu Chan has also consulted a lot of relevant materials before.

Zhuge Liang's wisdom, coupled with the knowledge of Liu Chan's later generations, after all these years of research, finally succeeded in creating a wooden ox and flowing horse. And according to Liu Chan's guess, today's wooden cattle and horses should be even worse than those in history.

Liu Bei looked at Liu Chan on the side when he heard this, saw him smiling, knew that what Zhuge Liang said was true, and hurriedly said: "The military advisor actually created such a divine object? Where is it now, take me to see it! ”

Zhuge Liang said with a smile: "Don't worry, Liang has ordered someone to bring it over, and now outside the hall, the lord can go out to watch it!" ”

"Oh? In that case, let's go out and have a look! When Liu Bei heard this, he took a group of civil servants and military generals out of the palace.

The wooden ox and horse were arranged under the steps outside the hall, and everyone went down the steps and saw the wooden ox and horse.

The wooden ox and the horse are not one kind of car, but two kinds of cars, the wooden ox is one and the flowing horse is one.

I saw that the wooden ox and the flowing horse were two wooden carts with a width of three feet and a height of about six feet and five inches.

The general structure of the wooden ox is that the carriage of the four-wheeled vehicle is equipped with a bull's head, and the double wheel is mounted on the front and rear strut axles, and the long and short struts are hinged on the strut axle, and the double wheels are hinged on the car body again, and the double wheel strut is shaken to support the ground and promote the wheel to rotate.

The general structure of the flowing horse is that the carriage of the two-wheeled vehicle is equipped with a horse's head and the double wheel is mounted on the back, and the general structure is similar to that of a cow and a horse. Whether it is a wooden ox or a flowing horse, it is mainly a wheeled vehicle driven by the principle of levers and connecting rods, and driven by struts.

Liu Bei and a group of civil and military officers saw these two novel cars, and they were all eye-opening, and they gathered around the wooden ox and flowing horse to watch, and they were full of taste.

Huang Quan observed the ox and horse carriage, and saw that the carriage was huge, and couldn't help but say: "Military advisor, this carriage is quite large, at least it can hold seven or eight hundred catties of grain, which is not much worse than the grain and grass transported by the carriage. ”

Zhang Fei shouted when he heard this: "Just try it, I'll see if this carriage is loaded with grain!" ”

After that, Zhang Fei was about to open the carriage, but after looking for a long time, Zhang Fei did not find the door of the carriage. Zhang Fei couldn't help but say: "Strategist, what kind of thing did you make, why did you forget to open a door, and this grain can't be loaded." ”

"Yi De Mo anxious, this door also has a mystery!" Zhuge Liang smiled faintly, walked to a wooden ox, put his hand into the cow's mouth, and didn't know what kind of mechanism was moved under the cow's tongue, and then gently pushed on the carriage, and the wooden board on the carriage was pushed and directly removed. I saw that the carriage was full of grain in cloth bags, and there were as many as six sacks.

"There's still a mechanism, good fellow, I'll try it!" Seeing this, Zhang Fei was very curious, walked to the flowing horse, put his hand into the mouth of the flowing horse and groped, but after touching for a long time, he did not find the location of the mechanism.

Seeing this, Liu Chan couldn't help but say: "Push and lift the horse's tongue, and the mechanism is under the horse's tongue!" ”

Zhang Fei heard that he did so in accordance with the law, and sure enough, he found the organ and opened the lid of the box smoothly.

"With so much food loaded, I don't think it's good to leave!" Zhang Fei then rolled up his sleeves again, lifted the double wheel and pulled the cart to walk.

There was a slope paved with stone slabs in the center of the steps from the outside square to the main hall, and there were patterns on it, similar to the mountain road, so Zhang Fei pulled the wooden ox towards the steps.

As Zhuge Liang said, the wooden ox flowing horse is extremely light, and it is not effortless to climb steeply, and it can even directly use the pole to stop on the slope without fear of the car body overturning.

Zhang Fei carried the wooden ox and the horse for a few laps, and everyone was relieved when they saw that there was no problem.
