Qin Wentian smiled and said: "Yes, after the yellow mud has been fired, the hardness will be greatly improved!!But if it is too high-ground building, steel needs to be put in it as the skeleton of the building!!"

"And what is steel?"

Zhang Juzheng said puzzled, and then he was shocked, and said: "The emperor is saying that the steel used to build swords and swords is precious, and it is not enough to build weapons, let alone to build houses."

"There are a lot of mines in Shenzhou, and the reason why steel is precious is because the forging method is too old!

Qin Wentian smiled and drew the railroad tracks on the table again.

"Zhang Qing, can you imagine that these two rails are made of steel?

You can think about the principle of the operation of the waterwheel, but the driving wheel is replaced with steam, and the steam is sealed in the turbine, circulating endlessly, and the pressure is extremely high.

"It's... This ......"

Zhang Juzheng was stunned when he looked at it, and said in surprise: "If this kind of train can really be manufactured, it will be an unprecedented change for all caravans!

"Zhang Qing, can you understand??"

Qin Wentian was also stunned, the clothes and bricks in front of him were relatively simple.

But the train is simply a product of several eras, Zhang Juzheng can still understand, then it is not simple.

Zhang Juzheng said softly: "The emperor said the ground in such detail, Martingale can naturally understand it!! Martingale is thinking, if the power that drives the train is changed to the Xuanshi activation to generate the ground aura, this speed is estimated to be doubled!!"

Qin Wentian patted his thigh, smiled and said, "Lift-reverse three, get Zhang Qing, I am very lucky!!"

Lan Meiji asked in a daze: "Your Majesty, Xiangguo, what are you two talking about, I can't understand a word!!"

"Haha, it's normal that Concubine Lan doesn't understand, and Zhang Qing understands it, so I feel strange!!But you don't need to understand these things!!Your task is to integrate the army and collect taxes from the Great Family!!"

Qin Wentian laughed, and continued to say to Zhang Juzheng: "With the Xuanshi as the driving force, I didn't expect that the Xuanshi explosion produces a great amount of earth aura, if it is sealed and rushed into the turbine!!

Zhang Juzheng asked suspiciously: "Your Majesty, what is the high-speed rail??"

"The high-speed rail is too complicated to say, and I can't understand it for a while!!"

High-speed rail is driven by electricity, although the principle of power generation is also very simple: find two magnets, wrap around the coil and rotate at high speed, and the motor will go in the opposite direction.

Qin Wentian was a college student in his previous life, and these basic principles are still clear.

It's just that the power system and motor system required to run the high-speed rail are too complicated, so he doesn't plan to tell Zhang Juzheng about the high-speed rail, in China, a technologically backward place, it would be very good to be able to build a train!!

"Look at this again!!"

As Qin Wentian spoke, he drew the simplest modern weapons such as pistols and artillery on the table.

"Charcoal, sulfur, saltpeter, these simplest materials, are mixed in a certain proportion to make gunpowder! Ignited with fire, the explosive power produced can even be comparable to the full force of the ninth-order martial artist realm! Based on gunpowder, the ground musket cannon is developed, although the power is nothing to the strong, but when it is put into the army, it will be invincible......

Qin Wentian smiled and explained to the three of them.

From the production of gunpowder, to the basic construction principles of muskets and artillery grounds, to the construction of high-rise buildings, foundations, steel, automobiles, and so on......

The ball is full of new things, gushing endlessly.

The three of them were fascinated by it, as if they had left Shenzhou University and were in the world of the 21st century.

"Zhang Qing, the queen, Concubine Lan, you must be very curious about how I understand these places.

Qin Wentian looked at Lan Meiji with a smile and said, "Concubine Lan, you should have Xuanjing on you, give me a piece, and I will show you another world."

"Concubines have."

Lan Meiji hurriedly took out a piece from the space ring, a light blue ground and a crystal-sample crystal, and handed it to Qin Wentiandi's hand.

This is a kind of memory storage crystal, which is roughly used to use similar tools such as a USB flash drive on the ball.

Memory images can be stored inside.

It's just that you don't need a computer to use Xuanjing, you need to be aura.

Warriors can use Xuanjing to directly link to their own minds, and record the images in their minds, which is more convenient and practical than transferring files on a computer.

The native of the Shenzhou Continent is generally used to record important things such as exercises and martial arts.

But Qin Wentian wants to store the earth, but this is not these.

Injecting the aura into this Xuanjing, Qin Wentiandi's mind was instantly connected to the internal space of the Xuanjing Land.

This is a blank crystal, so the space inside is also extremely dark.

He began to think about life on the earth, eating the earth, wearing the earth, the planes in the sky, the cars on the earth, and the iron in the bottom.

The city is lined with high-rise buildings.

Except for the ball humans, all the things that Qin Wentian was deeply impressed in his heart, and he could think of the earth at this time, he had all entered them into this Xuanjing.

Including the manufacturing method and general principle of these things, Qin Wentian entered them, and in a short time, this piece of Xuanjing showed the general appearance of the ball.

Immediately, Qin Wentian let go of the Xuanjing link with his mind, took the Xuanjing in his hand, and injected the aura.

But I saw the ball projected out of thin air in the air.

Airplanes fly in the sky, cars drive in the sky, and 10,000-ton ships swim in the endless ocean.

Machine guns and cannons fired continuously, sparks fired, and fragments flew.

The enemy fell in pieces.

"Jingran doesn't need to reach the realm of the Martial Emperor, just by virtue of this so-called airplane iron box, he can fly to the sky? With the two wings of the plane, the ground pressure difference between the top and bottom is generated.

"—an iron box with wheels, and then equipped with the emperor said that the internal combustion engine can run so fast?? This is much faster than an ordinary carriage, and there is no bump in the carriage.

"Your Majesty, are you saying that this thing is called a pistol ground, just with this little subway tube, it can shoot out a kind of thing called bullet ground, and it can kill the Martial King Realm!! And it is easy to make, you must understand that ordinary Xuan-level artifacts can't kill the Martial King Realm!!"

Zhang Juzheng, Xun'er, and Lan Meiji were all dumbfounded, and they couldn't imagine that there was such a magical thing in this world.

This completely upends their worldview!!

"Hehe, that's good."

Qin Wentian smiled, put away the Xuanjing, handed it to Zhang Juzhengdi, and said: "Zhang Qing, I have recorded the basic production methods of these things in this Xuanjing.

"The minister understands!!The minister will not live up to the high hopes, these things are commercially different from weapons, and the ministers will use new things to develop commerce, make money, open schools, and then build new weapons and strengthen the army."

Zhang Juzheng looked solemn, took this Xuanjing with both hands, and put it in his arms.

Qin Wentian nodded, this matter is handed over to someone else to do, he can't rest assured, but he will hand it over to Zhang Juzheng to do.

He believed that with his ability to do so, he would be able to do it.

Bi Jingqin asked the sky in his previous life that he was just an ordinary person, and it was impossible for him to understand the detailed manufacturing method, he only understood the principle.

He understands that gunpowder is formulated, and gunpowder is formulated, but he can't make gunpowder himself.

He understood the principle of the internal combustion engine of a car, but he could not build a car engine himself.

The list goes on and on.

He didn't even understand the principles of many things, so Qin Wentian entered the ground in this Xuanjing only because he understood the principles.

Now that Qin Wentian has recorded this Xuanjing, he has brought the new earth thought and the new land idea to Shenzhou University.

As for how much can be created in the end, and what kind of sparks will burst out, it depends on how many talents Zhang Juzheng can find.
