Zhu Yuanzhang was so angry that Han Du laughed back at him. He was so brave. He even ripped me off and hit me on the head.
Lao Zhu's words made Han Du feel nervous. Looking around at everyone's expressions, he suddenly came to his senses. Maybe these people didn't know the value of cement at all.
"I don't dare. Please listen to my explanation, Your Majesty." Han Du bowed his head quickly.
Misunderstanding, big misunderstanding.
If you have a misunderstanding with ordinary people, you will at best be separated from each other, but if you have a misunderstanding with Lao Zhu, it will be a head-scratching affair.
Han Du quickly explained to Lao Zhu, "The emperor wants to build the city wall with cement."
"Yes, isn't it possible?" Lao Zhu asked.
"Yes, of course it is possible to build walls," Han Du responded quickly, and soon changed the topic, "But in my opinion, the biggest role of cement is not to build walls."
"What is that used for?" Li Shanchang interjected and asked. As for the purpose of cement, he thought the same as Lao Zhu when he saw it for the first time, but now that Han Du said there are more important uses, he couldn't help but
Ask out of curiosity.
"When I returned to South Korea, I thought the greatest role of cement was to build roads."
"Used to build roads?" Xu Da, who was standing quietly aside and had some free time, asked in confusion.
"That's right," Han Du's confidence returned. No one else had ever seen a cement road, but Han Du said he had seen too many. "May I ask Wei Guogong, what will a road built with cement look like?"
"This," Xu Da pondered for a moment, "I haven't seen it before, so I don't dare to judge."
Han Du explained to Lao Zhu, "Your Majesty, the road built with cement is smooth and solid. The most important thing is that it is not afraid of rain erosion. Even under heavy rain, people, horses and vehicles can still walk freely on it.
"
"But, even so, so what?" an accompanying official asked.
Han Du smiled slightly and wanted to tell the official what "if you want to get rich, build roads first". The convenience of roads plays a vital role in the development of the economy and society. Not only that, roads actually play a role in the government's control of places.
Great enhancement effect. As the saying goes, "The mountains are high and the emperor is far away." Why are places far away from the capital easy to rebel? It's because the imperial court is beyond its reach. If there are convenient roads, the marching efficiency of the imperial army can be greatly improved. You see
See if you dare to rebel easily in these places.
But Han Du did not explain to this person, and turned to Lao Zhu and said, "Your Majesty, Duke Wei of Wei, both use troops. I dare to ask, how much of the national treasury will be consumed every time our army conquers the Northern Yuan Dynasty?"
When Xu Da heard Han Du's question, he just glanced at the emperor and said nothing.
The imperial court had always criticized Lao Zhu's Northern Expedition, so when Han Du asked him this question, his face became unhappy, but he suddenly came back to his senses and answered Han Du for the first time, "Every time the Northern Expedition
The consumption is about 3 million to 5 million guan."
"May I ask Your Majesty, how much of the food, grass and baggage account for this?" Han Du continued to ask.
"Probably, 70%." Lao Zhu answered easily as he realized something.
Xu Da and Li Shanchang, who were standing by, were surprised to see the emperor and Han Du answering questions and answers in perfect harmony. They had rarely seen the emperor face such a low-level official with such an attitude.
Both of them are extremely smart people. After thinking about it carefully, they came to some enlightenment.
"Seventy percent. Calculated from three million guan, that's still 2.1 million guan. The grain travels thousands of miles, which is less than 10%. More than 90% of the grain will be consumed in the transportation process."
Having said this, Han Du paused and said sternly: "And if there are roads built with cement, the efficiency of transportation can be greatly improved and the time for transporting grain can be greatly reduced. Reducing time is equivalent to reducing the amount of food."
Consumption during transportation.”
"Please see, Your Majesty," Han Du waved his hand and pointed at the concrete slab. "Before this material solidifies, it is like mud and can be made into any shape. After solidification, it will become hard and flat. The carriage is driving like this
On the road, there is no need to worry about the hidden dangers caused by the ups and downs of the road surface, and you can fly quickly on it."
"In the past, a horse could only carry two to three hundred kilograms of grain and grass, and could travel no more than twenty miles in a day. But if it is replaced by a carriage, a carriage can carry a thousand kilograms, and a horse can pull the carriage quickly on such a road.
Moving forward, we can travel more than a hundred miles in one day. The most important thing is that there will be no potholes on such a road, and we can travel day and night regardless of day and night. The efficiency can be increased by more than ten times than before, and the consumption of food and grass will naturally be reduced to insufficient.
Now it’s 10%.”
Han Du paused for a moment and said solemnly: "Your Majesty, just a Northern Expedition, the cement road can save the court more than one million guan of food and grass. I only sell it for 10,000 guan. This is really a price that cannot be lower."
Already."
After Han Du finished speaking, Zhu Yuanzhang and Xu Da's eyes both shone brightly.
Both of them were masters of the military. Although they didn't think too deeply about it when they saw something like cement for the first time. But after Han Du pointed it out, the two of them were enlightened.
Han Du only saw the advantages of cement roads in transportation, but the two of them saw a deeper role.
That is the cement road and its convenience for troop deployment.
The so-called military is expensive and quick.
Speed is the most important factor in using troops.
As for those who lead troops, there is no one who will not try their best to pursue speed. "From dawn to dusk, you can appear and disappear". This is what all generals have dreamed of since ancient times. This thought came to the minds of both of them at the same time.
.
Lao Zhu and Xu Da looked at each other in tacit understanding, and realized something in their hearts. "According to Han Du, this thing is really not expensive if we buy it for 10,000 yuan."
Han Du saw that Lao Zhu was satisfied, and he was also smiling.
"Your Majesty, Han Du has ulterior motives, deceives the country with his evil words, and intends to disrupt our country, the Ming Dynasty. Please punish him."
The smile froze on his face, why did he have ulterior motives? Han Du looked in the direction of the sound and saw an official in the official uniform of the Ministry of Industry among the crowd, bowing to Lao Zhu.
"My lord, it seems that I don't know you. Why do you say that my lord has ulterior motives?" Han Du looked at the official with an ugly face.
The conscience of heaven and earth, I am always thinking about Ming Dynasty.
"Han Du, don't think that no one knows about your thoughts. Let me tell you, if I am here today, your treacherous plot will never succeed." This man's attitude became even more arrogant, as if he had determined that Han Du was a traitor.
He glared angrily, as if they were born with a deep hatred and a sworn hatred.
But Han Du didn't know him, so how could there be such deep hatred for no reason? Suddenly, Han Du thought of a sentence that Xue Ministry of Industry once mentioned, that is, "Someone in the Ministry of Industry impeached him for despising Chao Gang because he paid salaries to craftsmen."
.
This guy is probably the one who impeached him.
It must be yes. Otherwise, why would you fire at him for no reason in front of the emperor?
Han Du laughed in anger. This kind of person really opposes for the sake of opposition. He mocked: "This is a good way to strengthen the border. How can I allow you to slander me?"
"Don't try to confuse things. Han Du, you just want the Ming Dynasty to repeat the same mistakes." The man pointed angrily at Han Du and turned to complain to the emperor, "Your Majesty, history books record that before Qin destroyed Han, he deceived Han and said that he would build a straight road.
It can quickly transport grain, grass and baggage, and can easily mobilize troops. As a result, after South Korea built a straight road to the border, the Qin army used the straight road to attack, penetrated directly into the Korean capital, and easily destroyed South Korea."
Turning to look down at Han Du, he accused righteously, "The Northern Yuan cavalry came like the wind, several times faster than our Ming army. You still want to deceive the emperor and ask the emperor to build a straight road. Are you doing it for the sake of one day going to the north?"
Yuan Tieqi can easily penetrate into the hinterland of our Ming Dynasty, what are your intentions?"
"Shabi." Han Du curled his lips.
"What did you say?" Although he didn't understand what Han Du meant, he knew that what Han Du said was not good, and he immediately glared at Han Du. If not in front of the emperor, he would have dared to look at Han Du.
Hands-on look.
"Say you are short-sighted." Han Du was not afraid of him, nor did he show any mercy to him, even if his official position was higher than his own.
I will not offend anyone unless they offend me. If someone offends me, I will destroy my whole family.
Besides, Han Du looked down upon these bureaucrats who were sucking blood from the craftsmen. He only paid salaries to his subordinate craftsmen, but these bureaucrats dared to impeach him. If he had the chance, he must get this situation back.
However, I still have to explain it clearly to Lao Zhu. If I don't explain it clearly, if Lao Zhu, who is naturally suspicious, really suspects that he has different intentions, then he will lose his head.
"Your Majesty is a military commander, so he naturally knows the cavalry very well." Han Du smiled and flattered Lao Zhu, "But I still have to explain it carefully today."
Lao Zhu looked as usual and said nothing, but raised his hand to signal Han Du to continue.
"The cavalry horses are nailed with horseshoes. When the horseshoes step on the grass, the horseshoes will sink deeply into the soil and play a stabilizing role." Han Du gestured with his hands.
These are just common sense. As soon as Han Du said it, everyone understood it.
"This is why the cavalry can fly across the grassland and come and go like flying," Han Du changed his words. "However, the cement road is as solid as a rock. Once the cavalry walks on it, it is impossible for the horseshoes to sink in.
Inside the concrete, it will not be able to stabilize the horses. Even in Chenkailai, horseshoes are as hard as cement roads, and slipping will occur easily when the two meet."
Han Du leaned over and picked up the hammer that Mao Xiang had dropped on the ground, placed it on the concrete slab and dragged it back and forth a few times.
Yeah, it's so smooth.
"Just like on a road paved with stone slabs, who dares to gallop on a stone road?"
