Dong He saw that the wooden ox and flowing horse were so magical, and couldn't help but stroke his beard and praise: "The military advisor is really Lu Ban alive, and the creation of this wooden ox and flowing horse has solved the problem of transporting grain and grass in Yizhou." ”

Zhuge Liang said: "This wooden ox and flowing horse, a cart can hold seven or eight hundred catties of grain, suitable for mountain walking, no need for cattle to pull the horse, greatly saving the loss of grain and grass on the way." In one day, it is possible to march thirty or fifty miles, which is roughly the same as the speed of the soldiers and horses. Positive, now you don't have to worry about sending troops to Yangpingguan to run out of food and grass, right? ”

In ancient times, soldiers and horses transported grain, if the road was far away, the road was rugged, there were ten stones of grain, and nine stones would be lost on the road, and when it was transported to the hands of the soldiers and horses in the barracks, the grain and grass would not be one out of ten. For on the road, men have to eat grain, and horses have to eat grass.

Take the carriage as an example, a carriage can carry thousands of catties of grain and grass, in addition to the equipped horses, if the road is steep on the way, the carriage can not walk with heavy loads, it needs to be transported by the people's wife, so it is generally necessary to be equipped with three or five people's husbands.

One to catch the car, two or three about to help the car, when the road is steep and difficult to move the manpower cart, it is really not possible to push the artificial camel transport.

In ancient times, there was no rich diet, so only by eating could you replenish energy, plus traveling, the physical exertion was even greater, so a person needed to eat three catties of food a day.

The configuration of a carriage will consume about fifteen catties of grain a day, and if the travel period is one month, it will consume four or five hundred catties of grain, plus the grain and grass consumed by horses, and the grain and grass of a carriage will be left when it arrives at the destination.

The advantage of the wooden cattle and horses is not only that they can walk the mountain road, but also that they can save grain and grass, and a person can manipulate it, so as to remove the loss of cattle and horses, as well as the loss of redundant people, the loss of grain and grass can be reduced by three or five percent, which is the most rare.

Li Yan sighed and said: "Strategist, although this wooden oxen and flowing horse can transport grain and grass in steep places on mountain roads, saving the power and manpower of cattle and horses, and reducing the loss of grain and grass, at least thousands of them must be built."

I see that your wooden ox and horse workmanship is quite complicated, now it is two months, and when the ice and snow melt and the road is dry, you can send troops in March at the latest, within a month, how can you create thousands of wooden oxen and horses? ”

Liu Bei also nodded when he heard this: "Well, this is a problem, even if you gather the people now, I'm afraid it's too late!" ”

When Zhuge Liang heard this, he said to Liu Bei: "Don't worry, don't worry, as early as last year, when the lord ordered the right side and Gongheng built military supplies, I asked them for some craftsmen, and the people went to Baishui Pass. In the mountains and forests outside the Guan, local materials were used to build wooden oxen and flowing horses, and now General Deng Xian supervised the construction in Guanzhong, so far, it is enough to think about it. ”

Huang Quan was surprised when he heard this: "I can't imagine that the military advisor asked me for a craftsman in the first place, just to create this thing?" ”

Zhuge Liang nodded and said: "Well, because it needs to be careful at this time, I have something to hide, I hope you will forgive me!" ”

Fa Zheng beside Liu Bei suggested to Liu Bei: "Lord, with this wooden ox and flowing horse, the problem of grain and grass transportation has been solved, and Pang De is willing to surrender, so attacking Yangping Pass like this can be considered!" ”

"Hmm!" Liu Bei nodded and said, "Go in and say!" ”

The people returned to the main hall and were again divided into left and right sides.

Zhang Fei arched his hand and said: "Big brother, now the military advisor has created this wooden ox and flowing horse to solve the problem of grain and grass transportation. Then Pound is willing to surrender to the eldest brother for the sake of the interior. In this way, we can get out of Yangping Pass and deal with Xiahou Yuan, I Zhang Fei is willing to lead a partial division to kill Xiangyang Pingguan, solve Xiahou Yuan first, and then enter Hanzhong to help the eldest brother kill Cao Cao! ”

"This ......" Liu Bei listened to Zhang Fei's words, and it was a little difficult to decide.

Now that he has finally accumulated so many soldiers and horses, he has the ability to confront Cao Cao head-on, and the 50,000 army is out of Yangping Pass, once he fails, Liu Bei will be greatly injured, but Liu Bei does not dare to take risks.

"Father!" Liu Chan saw Liu Bei hesitate, and finally gave up.

Liu Bei looked at Liu Chan and asked, "What do you think?" ”

Liu Chan arched his hand and said: "The child thinks that the troops should be divided into two ways and send a partial division to attack Yangping Pass!" First of all, on Xiahou Yuan's side, the military division has already analyzed it, so I will talk about what the military division has not analyzed.

Xiahou Yuan is now stationed in the military capital, as soon as the spring arrives, he will attack Yangping Pass, his father thinks, he will expect his father to also send troops to attack Yangping Pass? ”

Liu Bei shook his head and said: "I think it shouldn't be, the Sword Pavilion to Yangping Pass, thousands of miles of mountain roads, Xiahou Yuan doesn't know that our army has wooden oxen and flowing horses, I'm afraid I won't expect our army to leave Yangping Pass." ”

Liu Chan smiled: "Isn't that enough?" The wooden ox and flowing horse solved the problem of grain and grass transportation, and at the same time there was Pang De as the internal response, plus Xiahou Yuan was brave and unstrategic, and his soldiers and horses were not suitable for mountain warfare, and Xiahou Yuan would not have expected that our army would go out of Yangping Pass, this is the five major opportunities for our army to win, what else can my father not decide? ”

"Hmm!" Liu Bei nodded when he heard this, but he still didn't make a decision.

Liu Chan continued: "Then the child is analyzing and analyzing the problems in Hanzhong, now Zhang Lu is about to face the attack of his father and Cao Cao, he wants to live, only to surrender one of Cao Cao and his father, who does his father think, Zhang Lu will take refuge?" ”

Liu Bei sighed and said, "This ...... A better choice should be Cao Cao! ”

Liu Chan nodded and said: "Yes, when the time comes, Zhang Lu may surrender to Cao Cao in order to save his life, and Cao Cao will occupy Hanzhong when he gets Zhang Lu's surrender."

Even though his father's entire army went out of Hanzhong and occupied an advantage of 50,000 troops, Cao Cao was surrendered by Zhang Lu and supported by the military and people in Hanzhong. In this way, the father's extra 50,000 people are not an advantage, and after a long time, the grain and grass cannot be maintained, and the father is worried about defeat.

Therefore, if he can send a partial division to defeat Xiahou Yuan, Xiahou Yuan's 50,000 soldiers and horses will suffer heavy losses and lose their spirit, and Cao Cao's soldiers and horses will also lose their fighting spirit. And the partial division from Yangping Pass to the east into Hanzhong, with the momentum of defeating Xiahou Yuan swept in, and his father was able to occupy many cities in Hanzhong, based on this, even if Zhang Lu surrendered to Cao Cao, Cao Cao would not occupy an immediate advantage.

In addition, Xiahou Yuan's army was defeated, but his father was more advantageous, so defeating Cao Cao in this way wouldn't he have a few more chances of winning? ”

"My son has a point!" Liu Bei patted the table and said: "The whole army cannot occupy an advantage in Han, but is a disadvantage. Dividing troops into Yangpingguan can create an advantage, so what else can I not decide? I intend to divide the troops into two routes, one is that I lead 100,000 troops out of Bazhong into the hinterland of Hanzhong, and the other 50,000 are partial divisions, out of the Sword Pavilion to attack Yangping Pass! ”
