She, Yingyin, has money.

It's just R&D, how much can it cost?

Jiang Xia pursed the corners of his mouth, slightly provoked his brows, and gave Xiang Lian another suggestion, "You can lay a kind of track, use the steam engine as the front of the locomotive, and drive all the carriages behind to move forward, pulling people and goods." In addition, it is also possible to build a kind of small car, the kind that can run fast by one person. ”

Anyway, the princess has money.

Want to develop a car?

Tut......

That's a bottomless pit!

There is no best, only better.

No matter how much money you throw into it, you can't see a splash.

It's not about spending your own money, and it's not distressing.

Xianglian pondered for a moment and asked a very critical question, the plane he recently developed can fly a little, but only a little, and it is very difficult to maintain a long-term flight state.

In addition to this, the runway is also a key problem, which directly affects the speed state at takeoff.

"Sir, the carriage needs to run on a well-groomed road, so after the cart is made, does it also need to build a new road?"

Jiang Xia nodded, "Theoretically, if you can build a car made of steel, as long as the chassis is a little higher, it will not be a problem to run on the current road." Of course, if there is a sufficiently hardened road, it is best to run a little faster and not so bumpy. ”

Harden......

It occurred to him that there were also some people in the factory who were developing various ways to use minerals, and among them, there was a very hard product, and they had discussed whether this product could be used to build the city wall.

"Sir, recently when we were refining oil, we found a product of petroleum, when heated it is a black liquid, and after cooling, it will become a very hard solid, if this product is used to pave roads, I wonder if it is feasible?"

Jiang Xia was stunned for a moment, "You actually refined asphalt?" ”

"Asphalt?" Xiang Lian also looked confused, "What is asphalt?" ”

"Uh...... It's a substance that can pave the way. Jiang Xia scratched his head, he had seen the staff paving the road when he was passing by.

But......

He doesn't understand either!

"However, while the asphalt is very load-bearing and generally does not crush, it can be a bit laborious to install. At the very least, the road has to be flattened, with another layer of gravel on top, and then asphalt, and then flattened, and then asphalted, and then flattened......"

That's pretty much the process, but ......

To be honest, Jiang Xia feels that with the current level of science and technology, there are not many cars, and paving asphalt roads is really not cost-effective.

How many people in Daqin can't afford to eat, who will use the whole asphalt road?

Jiang Xia shook his head, "If you want to lay an asphalt road, you might as well study cement." ”

"Cement?"

"Hmm."

Jiang Xia roughly described it, "It's probably a kind of messy thing ground into powder, and then add water and mix it, spread it on the ground, and when it dries, it can be very hard, this thing can build a house, make a city wall, and it should be a little more useful than asphalt, right?" ”

Asalian, "......"

Xiang Li'an glanced at Jiang Xia resentfully.

Sir has proposed something that needs to be developed!

What does it mean to grind messy things into powder and stir them with water?

What the hell can be cured by grinding it into powder and adding a little water?!

"Sir said that this wall could be used to build a wall? So if I put the planks in a circle and pour cement in the middle, and when they are dry, can they be used as walls? Could it be that the Great Wall can also be watered like this? ”

"Yes."

However, yes, yes.

The cost is huge......

I don't know if the princess can afford it.

Ying Yinyan heard Jiang Xia's affirmative answer, the corners of her mouth almost grinned behind her ears, and her eyes were shining, "In this way, no matter what you want to build, as long as you enclose a model with wooden planks or something like that, and fill the middle with cement, you can quickly build an indestructible thing?" ”

"Hmm...... It's really fast, but it's not indestructible. ”

The joy on Yingyinyan's face was stunned, and a question mark slowly popped up on her head, didn't she say that there was no problem with the car walking on it?

Why not indestructible?

"The princess has also seen the lethality of gunpowder, as long as a gunpowder is thrown over, it is estimated that no matter how strong the city wall is, it will not be able to keep it. If one isn't enough, throw a few more and you'll definitely get it. ”

Gunpowder......

Hearing that gunpowder was needed to destroy the cement city wall, Ying Yinyan's heart instantly relaxed again.

Who else but Mr. could make such a killing weapon as gunpowder?

If it weren't for Mr., they wouldn't even have imagined that there could be such a powerful weapon as gunpowder!

In other words, their Great Qin has the strongest spear, gunpowder!

And the strongest shield, the concrete wall!

"No matter how much it is, I'll come out! Mr. Aisato just develops it! Ying Yin Yan added, "Lack of people, lack of money, I will solve it!" ”

Jiang Xia glanced at Yingyin Yan, so confident? "Did the princess send a message to Your Majesty?"

"Hmm!" Ying Yin Yan raised her chin proudly and said happily, "I quickly sent the news to my father yesterday, and asked my father to publicize the rewards for many students in the palace newspaper, and then call on people who also have a talent for invention to come to Yangwu!" When the time comes, there will definitely be a large number of talented people coming to Yangwu! Under the heavy money, there will be brave men! ”

Jiang Xia, "...... The princess was right. ”

Yingyin Jiaojiao laughed twice, "Sir, don't worry!" When your new book is finished, I will definitely let my father praise Mr. in the palace newspaper whether there is anything in the world or the earth! The new book is sure to sell well! ”

Jiangxia, "......"

"But isn't it time for the gentleman to write a book?"

Jiangxia, "......"

Headache.

Jiang Xia waved his hand and motioned for Xiang Li'an to go back first to continue research and development, and came to Wanguo Kanyu with Yingyin Yan with a headache.

I really can't go on, so I can only work hard in anger.

"Where does the princess think it would be better for me to start from?"

"Hmm......" Yingyin Yan held her chin and thought for a long time, "Sir, why don't you start from Canghai County?" In this way, you can go all the way west and write a Journey to the West! It not only includes my Daqin, but also writes all over the world! ”

"No way!" Jiang Xia refused without hesitation, "You can start from anywhere, but Canghai County can't." ”

"Huh? Why is that? Yingyin looked at Jiang Xia puzzled, "What's wrong with Canghai County?" ”

"The people of Canghai County like to take other people's things for themselves, if I set out from Canghai County, after thousands of years, maybe they will say that I am from Canghai County, the world is discovered by Canghai County, and even the world is from Canghai County! I, Jiang Xia, am a Great Qin person in life and a Great Qin ghost in death, and I must not be taken advantage of by Canghai County. ”
