The two of them walked by the water and slowly walked towards Afang Palace.

The road was muddy, and a little mud was stained on the weeds that were quietly peeking out, gray and green, and there was a different scenery, which belonged to a quiet place, but was broken by the roar in front.

The emperor was not in a hurry to come, and deliberately slowed down, but Li Zhao did not dare to trespass, although he was anxious, he walked step by step, and slowly, a corner of Afang Palace appeared in front of him.

This is the second time Yingzheng has seen the giant thing crawling, and even so, he is still very interested.

"Li Zhao! How did these giants come about? It's really my blessing to Daqin! If I used such a huge thing everywhere in Great Qin, what would be the situation. ”

Inadvertently, the emperor suddenly asked, which made Li Zhao unable to answer for a while, how did he get these things, can he say? No one will believe it even if they say it, but don't say it! The emperor will definitely hold on to it.

The emperor is in Shanglin Yuan, I am afraid that he knows every move of Shanglin Yuan, if he lies outrageously, it will inevitably damage his image in the emperor's heart.

But how to say it? Did it fall from the sky? It is impossible to say: "One day Your Majesty will know how it came about." ”

This is a refusal to answer, in fact, the emperor is not entangled, he said this only to lead to the next words: "Everyone has their own secrets, you don't have to say it, but there is a little I must say, it is black water." ”

"Why did you want to transport the black water back to Shanglin Yuan?"

Li Zhao was stunned, knowing that the emperor asked so much just to say this, he couldn't help but secretly despise it, and how could his thoughts be known by ordinary people, even if the emperor was not an ordinary person.

"It's useful."

"What's the use?" The emperor stood still and looked at Li Zhao intently.

Li Zhao gave up his hand, and did not hide it: "For epoch-making purposes, you must know that black water is industrial blood, as long as you have it, you can make Shanglin Yuan modernize." ”

This is a little difficult to understand, of course, Li Zhao also deliberately did this, the purpose is not to ask His Majesty, some things have to wait until they are done to be known, and the effect is the best.

But the emperor did not obey his wishes, and reprimanded: "Tell the point." ”

Li Zhao scratched his head, knowing that he couldn't fool around anymore, so he pointed to the moving bulldozer not far away and asked, "Presumably Your Majesty has already seen this thing!" ”

The Emperor came here to see those machines without much reaction, presumably he had already seen them.

"Of course! This huge thing is a good thing, and it is enough to make my Great Qin prosperous. ”

This is the highest rating.

Li Zhao smiled and continued, "Then Your Majesty does you know what this thing needs to function?" ”

"Gasoline, of course."

Li Zhao bowed his head, presumably the emperor already knew all the machines in Afang Palace, so it would be easy to do, so as not to explain again.

"Then does Your Majesty know how the gasoline comes from?"

The emperor also wanted to know this, but Xiao He didn't tell it, no, Xiao He didn't know it, I'm afraid that the only one in the world who can know is Li Zhao.

Shake your head and listen.

"It's from Blackwater."

"Blackwater?" Ying Zheng raised his head and glanced at Li Zhao, thoughtful.

In the minds of the Qin people, black water is not very useful, at most it can play some role on the battlefield, but it is completely out of tune with gasoline.

Gasoline can make these huge things work, no matter how heavy the object, no matter how fluffy the soil, no matter how much work, it can handle it, it is a hundred times stronger than the people, such a good thing, how can it be compared to black water?

Not to mention that the gasoline comes from Blackwater.

"What's the explanation?"

The amount of knowledge involved is too great, even Li Zhao can't say clearly, even if he knows, the emperor may not be able to accept it, so he made a long story short: "To put it simply, gasoline is refined from black water, the process is too complicated, I can't say it at the moment, in a word, there is no gasoline without black water, and black water is more valuable than gasoline." ”

"In addition to refining gasoline, black water can also refine chemical raw materials such as asphalt, which has many benefits."

"As long as I go to Lin Yuan and master the black water, I can make it look new again, and it will be ten times better than Xianyang."

Saying so much in one breath is that he doesn't want the emperor to ask questions, but his time is very limited.

However, because of this, the emperor's appetite was aroused, and he was in desperate need of milk like a baby waiting to be fed.

"Asphalt? Chemical raw materials? Ten times better than Xianyang? Seriously! ”

The emperor showed a childlike curiosity.

Li Zhao was cold, he really underestimated the emperor's thirst for knowledge, perhaps, this is the desire of the king of a country to be strong!

"Seriously!"

Ying Zheng raised his head longingly, his wrinkled face suddenly became rounded, and he asked urgently, "What is asphalt?" What are chemical raw materials? ”

Li Zhao scolded himself a hundred times in his heart, he really had nothing to do, why did he say this to a person in an uncivilized place? This is to find guilt, but the emperor asked so, can he not answer?

He responded: "Chemical raw materials are very profound, and Your Majesty can enter the hall to understand when you have time." ”

After these days of development, the amount of knowledge in the school has developed from breadth to depth, and it has involved chemistry, from which you can understand.

Ying Zheng is the head, he has also heard that there are countless lewd techniques that can be learned in the school, attracting more and more people, if he has time, he really wants to explore.

"In short, asphalt is a kind of chemical raw material, which can be paved with a road, which is comparable to a cement road."

"Comparable to a concrete road? There is still such a thing in the world. ”

Ying Zheng was surprised!

The cement road is the most magical road he has ever seen in his life, even Xianyang does not have such a road, he once hinted to Li Zhao, let him lay the cement road in Xianyang, but Li Zhao tactfully said that cement is rare, there is no superfluous at the moment.

In other words, cement is hard to come by, and it's hard to find.

And the asphalt paving road is comparable to the cement road, then, if the asphalt is refined from black water, Xianyang Road is not like the cement road in Linyuan?

This is pleasant news.

But, how much does it cost? Is it easy to get? That's a problem.

Can't wait to ask: "How easy is it to refine asphalt?" How much does it cost? ”

Li Zhao said truthfully: "If the chemical workshop is built and mass-produced, it is not difficult, and the price is very little compared to cement. ”

This is not a lie, asphalt is a waste produced in petroleum refining, which was not too expensive in the previous society, so some cities paved asphalt roads in order to save costs.

"So, asphalt is better than cement?"

"So to speak." Li Zhao nodded.

Ying Zhengle blossomed, but he forcibly suppressed this joy, revealing his usual attitude, and said, "Naqing." Maybe it's a request, and even the title has become affectionate, "Let's build a workshop!" Refining asphalt as soon as possible is also good for Xianyang. ”
