The refining of core modules, gold and jade made of alloys of fine steel and jade is one of them, which is an indispensable material.

However, Zhao Yu specifically summarized and studied the method of using ordinary methods to smelter gold and jade using steel furnaces. In the eighteen volumes given to Cao Mengde, there is a detailed smelting process. This is not only because Zhao Yu is unwilling to turn Taihe Villa into another Zhaozhuang, or into a noisy processing factory.

A deeper reason is to cultivate people's smelting ability.

Otherwise, you only need to transport the fine steel and jade into Taihe Villa in batches and directly put them into the magic instruments, furnaces and cauldrons, and there is no need to summarize the ordinary smelting technology.

Perhaps people can get a lot of inspiration from the smelting process, and then innovate and evolve various smelting methods of other alloy metals.

Many times, as long as there is a beginning for certain things, people will suddenly realize it.

Oh, so that's OK.

Through such means, the effect of indirectly promoting social productivity is achieved.

Of course, keeping the quietness of Taihe Villa is also an important reason.

After all, 99% of the impurities will be removed by fine steel and jade through the magic weapon furnace and cauldron. The material required to refine a three-inch square module is one hundred times its volume. If steel and jade are transported directly, it is impossible to make three or five hundred power modules that are submerged in the courtyard at one time.

In that case, the entire courtyard will no longer be quiet.

So let Cao Mengde complete this step outside first, smel out gold and jade and then send it to another courtyard, so that the tranquility of another courtyard would not be broken.

Then the machine carriage carried the most powerful princes in the land of Shenzhou and the important civil and military officials under his command, and instantly soared into the sky.

If an accident occurs and Zhao Yu cannot rescue him, all peace in the high altitude will be broken instantly.

"The three operating levers on the operating table, the left one is used for starting and closing. The middle one is for acceleration and deceleration. The right one is for steering, turning, turning, rolling and other details. Of course, rolling and other things are best not to play with it."

Zhao Yu laughed and turned the operating rod on the right, and the machine car in the air suddenly turned 360 degrees. Cao Mengde and others couldn't help but fall back. If they hadn't turned it fast, they would have turned back in an instant, and everyone would have been on their heads and feet.

"gentlemen!"

Cao Mengde's face turned pale.

Zhao Yu laughed: "How about it, it's full of functions? I don't have too much decoration in my machine car. The speed car you make yourself in the future can take this into consideration. The designed seats can fix people, so there is no problem."

Then Zhao Yu demonstrated to everyone the functions of acceleration and deceleration, turning and turning.

Finally, he returned to Puyang and landed again in the open courtyard of the provincial governor's mansion.

When he walked out of the machine car with a heavy head, Cao Mengde felt light and unable to stand steadily.

Zhao Yu supported him: "It's good to get used to it in the future."

"The core power module consumes a lot of materials." Zhao Yu said as the group walked, "Although the module is three inches square, its total weight is more than fifty kilograms. For every time a module is refined with a magic weapon, the material consumed is 100 times its total weight. More than 5,000 kilograms of fine steel and jade are required to make such a piece. The last time, more than 100,000 kilograms of fine steel and nearly 100,000 kilograms of jade were made, and only three modules were made after refining the magic weapon furnace and cauldron."

"in this way..."

After hearing this, whether it was Cao Mengde, Xun Yu and others, the joy in their hearts was reduced a lot in an instant.

"This is too much consumption, right?"

Cao Chun couldn't help but speak, "Let's not talk about jade for now, more than 100,000 kilograms of fine steel are enough to create thousands of sets of excellent military armor!"

Zhao Yu nodded slightly: "That's true."

He said: "It is inevitable that high consumption is inevitable. Who makes this thing fly? Even if you don't stack the hanging talisman and eliminate its flying ability, the speed of galloping on the ground can still shake the war horses ten or dozens of times."

Zhao Yu said carefully: "The territory of our Xia people actually formed a relatively fixed framework during the Zongzhou period. By the Han Dynasty, although it gradually expanded, it was not big. It was not that the emperors of all dynasties were unwilling to rule a larger territory, but that they could not rule. Meng De and Wen Ruo, you know more than me."

Cao Mengde couldn't help but nodded repeatedly: "What the sir said is that the empire's territory is too large, and the rule of the central court weakened with the expansion of the territory. Why the border areas have never been stable is largely due to this reason."

Xun Yu also said: "The lord's words are reasonable. For example, after the incident in the Western Regions, it has been a year and a half since it was passed to Chang'an or Luoyang, and everything is too late. Even if you know it in time, because the journey is long, it is too late to dispatch troops and generals. This is beyond the reach."

"Yes, it's beyond reach." As he said that, he entered the lobby.

After each of them sat down, Zhao Yu said: "The key is transportation and communication."

He said: "Meng De and you all have experienced it just now. My machine car weighs more than 60,000 kilograms. Its flying speed can reach a speed of more than ten times the speed of sound at the fastest."

"Oh by the way." Zhao Yu quickly explained: "The speed of sound is the speed of sound transmission when we speak. How to measure it? One hundredth of an hour is counted as one second, and the speed of a sound is 340 meters, which is a little more than one hundred and thirteen meters."

"The speed of the machine car is more than 1,133 meters per hour."

At this time, Xun Yu continued: "Seven and a half miles."

"Yes, Wen Ruo's talent is quick. The speed of the machine is more than seven and a half miles per second. Meng De, do you think it will take to go from the easternmost part of the Han Dynasty to the westernmost part of the Western Regions?!"

Cao Mengde couldn't help but count carefully.

"From Youzhou Lelang to Dayuan in the Western Regions." Xun Yu reminded: "There are 14,000 miles."

Cao Mengde thought about it this way, his eyes slowly widened, and his mouth slightly opened: "Two moments?!"

Zhao Yu nodded with a smile: "No, it's only two minutes. Eat a little slower, and you won't be able to use the effort of a meal."

"hiss!"

The sound of sucking cool air suddenly sounded in the lobby.

"Meng De, think that if there are 1,000 such speeding cars, each with thirty people, you can send 30,000 troops from Youzhou Lelang to Dayuan, the Western Regions within a meal." Zhao Yu said with a smile: "No matter how far away the border, no matter what happens, the news can be conveyed to your hands at most. Is there any whip that goes without saying anything?"

Cao Mengde slapped the table with his hair and beards on the table, and his hair was wide open: "Don't talk about a meal, it's time to have three or five days!"

"Yes, it's still time for three or five days." Zhao Yu said: "This core power module can carry up to 20 million kilograms of huge objects flying across the sky. The speed can be maintained at about 30 feet per second. It is one-thirty of my small motor vehicle. Such a giant can carry thousands of people at one time, multiple three or five seven or eight, and can easily run tens of thousands of troops across the territory of the Han Dynasty within eight hours."

"So, Zihe, do you still think that a module is not worth a thousand sets of soldiers?"
