How did you, a prisoner on death row, become an important weapon of the country? Yecheng Gao Weiming

Mayor of Huangling Town, Feng Lixin?

Because it can withstand thousands of troops and horses galloping on it, is it called a road?

Zhu Youjian blinked his confused little eyes, still puzzled.

Now that the old man had started talking, he simply continued.

"My lord, that's not all!"

"This road is not afraid of heavy rain and snow, nor is it afraid of sunlight erosion. It can also withstand the crushing of tens of thousands of stones. It can be said that it has many wonderful uses and many benefits..."

Zhu Youjian was completely stunned.

Not only him, but Lu Wenzhao and Shen Lian behind him were also shocked.

What kind of road surface is not afraid of heavy rain, snow, wind and sun, and can withstand tens of thousands of stone weights?

It also……

What a nonsense.

You know, at this moment, the official road of Ming Dynasty is still a loess road.

Not only the official roads, but also most of the roads in the city.

Only Kyoto, Nanzhili, and the wealthy southern cities will lay blue bricks in the city to facilitate walking.

So this creates a serious transportation problem.

Once there is heavy rain or snow, the roads all over the country will be muddy and impossible to walk on.

No one could leave, let alone the caravans carrying goods. They had to wait for the heavy rain and snow to stop before they could move forward.

Sometimes heavy rain washes away the roadbed and even requires a diversion.

The journey that often takes a few days can take half a month or even a month.

But now looking at the road under his feet, Zhu Youjian looked in disbelief.

But it’s okay if he doesn’t believe it.

Because there was a heavy rain in Kyoto during the day yesterday, causing serious water accumulation in the city at this moment.

The three of them came galloping all the way, and the horses were as dirty as mud monkeys.

But now.

The road inside the archway is clean and tidy, with no trace of rain.

Where did all the heavy rain go?

Zhu Youjian may not have thought of anything else, but Lu Wenzhao and Shen Lian already looked ecstatic.

Both of them were born in the military, so they thought of it immediately.

If such roads were laid all over the country, wouldn't they be connected in all directions?

No matter how inferior a horse is, it can become a thousand-mile horse.

Especially to the land leading to Liaodong, if there is a road, there will be no obstacle to transporting military supplies.

You know, after several years of fierce fighting between the Ming Dynasty and Jiannu, the city was unfortunately lost many times because supplies and reinforcements did not arrive in time, and there was no chance of regaining it.

If Liaodong were all roads, would it be like entering an uninhabited land?

Thinking of this, Lu Wenzhao came over excitedly, grabbed the old man and asked urgently.

"Old man, I would like to ask you, do you know what this road is made of?"

The old man was suddenly caught by Lu Wenzhao. When he saw the opponent's waistband, he was shocked again when he found out that it was actually the Jin Yiwei Zhenfu Envoy.

"Uh...this...this...this..."

Nest grass!

The big devil in charge of the prison!

If an ordinary person was caught by Lu Wenzhao, he would probably be scared to death on the spot.

The old man didn't collapse on the ground, so he was quite brave.

"Lu Wenzhao, don't be rude!"

Seeing this, Zhu Youjian frowned and shouted coldly, ordering Lu Wenzhao to let go quickly.

Then he said with a smile: "My father-in-law, he is a rough man, don't get along with him."

"But what he asked was because my nephew was confused. How was this road built?"

Zhu Youjian also realized the importance of roads to transportation and military warfare, and couldn't help asking urgently.

The old man was completely confused.

When will a sixth-grade small household be able to command an envoy from the fourth-grade Jinyi Guard Town?

But he didn't think much about it, and said to Zhu Youjian with his smile restored.

"Sir, hehe, you have asked the right person."

"If you ask other people, you may not know the cause and effect. But this little old man has been following Mr. Feng since the beginning of the construction of this road and witnessed the whole process."

Zhu Youjian's eyes lit up when he heard this: "Old man, please...please teach me quickly."

The other party touched his gray beard and said: "The main constituent materials of this road. Oh, by the way, sir, you may not know what materials are. Materials are the components of matter, which can be used to form finished products. This involves material chemistry. Waiting for basic knowledge..."

Zhu Youxiao became more and more confused and could only reluctantly listen.

"The main material of this road is composed of the residue after petroleum refining, which is called asphalt. After adding some viscous agents, it will be in a high-temperature state after smelting, and then it will be poured on the roadbed and smoothed..."

oil? Refined? asphalt? Debris? Thickener? High temperature state...

Zhu Youjian, Lu Wenzhao, and Shen Lian went completely crazy.

There are so many nouns, but I can’t understand any of them.

What the hell is this girl doing!

But when it comes to oil, all three of them know it.

Petroleum, Shen Kuo, a scholar of the Song Dynasty, once summarized it in one sentence.

It comes out of the stone, and there is water in the stone. The water turns into oil, the color is like ink, and the black is like paint, which is not as good as pine ink. It can be used for burning, and it burns very brightly...

What we are talking about here is petroleum, the oil-like substance that comes out of stones.

As early as the Qin and Han Dynasties, some people discovered oil and burned it.

Since then, most of them have been produced in the Tianfu area and are not very well-known.

Zhu Youjian felt that it was a miracle.

In addition to burning, this thing can also be smelted, and the resulting slag can be made into roads?

So……

What is it smelted out of?

Seeing Zhu Youjian's curious baby look, the old man smiled again.

"Sir, the refined products are gasoline, diesel, kerosene and lubricating oil. Each of these oils has their own magical uses. I will show you to you when I have the opportunity."

Zhu Youjian:......

Lu Wenzhao:......

Shen Lian:......

For the first time, the three of them felt like idiots, unable to understand anything the old man said.

I wanted to ask again, but the old man stopped talking and only said that it involved some confidential technology in Huangling Town.

If it were leaked any further, I'm afraid it would make Mr. Feng very unhappy.

Seeing this, Zhu Youxiao had no choice but to suppress his doubts and smiled again.

"Old man, you and I are destined to be together. My nephew happened to be ordered to find Mr. Feng, whom you mentioned, to enter the palace to be a saint. Why don't you serve as a guide and lead my nephew on a journey?"

"Um...this..."

There was a hint of vigilance in the old man's eyes.

Why did Jin Yiwei suddenly come to see Mr. Feng?

Entering the palace to meet the saint?

Emperor Zhu Youxiao has long ignored the affairs of the state. He spends his days and nights declaring money, and even tinkering with wooden utensils during his free time. Where can he find Mr. Feng to do business?

But he also knew that some questions should never be asked.

Once asked, it will become evidence for Jin Yiwei's arrest.

The old man wanted to refuse, but looking at Lu Wenzhao looking unkind, he smiled bitterly and could only nod.

"Forget it, I have nothing to do, so I'll just take the three adults for a walk."
