Chapter 158 Cooperation ([-])

Han Qing looked at the man who looked like he was stepping on a wheel, and his eyes were fixed on the wheel that he was stepping on. The more he looked at it, the more magical he felt.

Why has no one thought of manpower to step on the axle wheel before, and the axle wheel can actually move?
If the axle wheel is similar to a carriage, isn't it like a human-powered carriage?

It has to be said that Han Qing's brain is also very big. Isn't this what he thought of the shape of the human-powered tricycle in the previous life?

Han Qing was extremely shocked. He withdrew his eyes from looking at the hammer crusher, and looked at Zhu Qiao Yurong with an indescribably complex light in his eyes: "Did you make this object yourself?"

Of course Han Qing knew that Qiao Yurong would not come out of the house for three days and three nights, but he never thought that such a shocking thing could be built in three days.

Qiao Yurong smiled, the bright and moving smile was like the morning rain, and she nodded confidently: "Yes, this king did it, isn't this king amazing?"

Han Qing rarely nodded in agreement: "It's very powerful, my lord has impressed me."

Han Qing's honest approval made Zhu Yurong's face slightly blush.

This Han Qing was usually cold and indifferent. He either laughed at himself or spoke sarcasticly to himself. This was the first time he spoke with praise like this.

It made Qiao Yurong feel light in his heart, it was important to be comfortable, and he laughed even more: "This king can not only do this, but also do better things."

"Oh, what good stuff?" Han Qing took the opportunity to ask, with meaningful eyes.

Qiao Yurong was about to say something, but Eunuch Mo suddenly said quickly, "My lord, didn't you come to see the cement?"

Oh yes!

Qiao Yurong was disturbed by Eunuch Mo, so that she forgot what she was going to say, turned her head to Han Qing and said, "Brother Han, come, I will build the cement road for you, but the concrete road will have to wait until tomorrow."

As Qiao Yurong spoke, she couldn't help but pull Han Qing, and walked forward.

Before Han Qing saw the big iron box, he was only curious about the concrete road, and his expectations were not deep. After seeing the iron box, he had a lot of expectations for the concrete road.

Qiao Yurong pulled Han Qing to an open space, and said, "Brother Han, wait for a while."

As he said that, Qiao Yurong hurriedly moved towards the pile of iron ore powder and other places, and pulled Eunuch Mo to speak.

How could Han Qing not know that this was Qiao Yurong trying to avoid herself.

But it doesn't matter, Qiao Yurong must have his own purpose for throwing this cement road, and he is not afraid that Qiao Yurong will not tell the truth later.

Han Qing's eyes were as faint as mountains and seas, as deep as the sky, shining with an inexplicable expression.

Qiao Yurong was indeed avoiding Han Qing. She didn't want to reveal the cement road blending formula to Han Qing so soon, and she pulled Mr. Mo to ask him about the water and the ingredients he needed: "Old Mo, both limestone and clay are transported." come yet?"

Limestone has been obtained in China since early in history.

Lime appeared in the Zhou Dynasty in the 7th century BC, and the lime in the Zhou Dynasty was fired from the shell of a large clam.The main component of clam shells is calcium carbonate, which will be calcined until all the carbon dioxide gas escapes to form lime.

There is a record in "Zuo Zhuan": "Duke Wen of Song Dynasty died in August of the second year of Cheng Gong (635 BC), and mirage ash was used for burial thickly."

Mirage ash is a lime material fired from clam shells. It has been found in the Zhou Dynasty that it has good moisture absorption and moisture resistance and gelling properties.

In the ancient times when thick burials were advocated, mirage ash was used as a cementing material in the tombs to build mausoleums and so on.In the book "Tiangong Kaiwu" of the Ming Dynasty, there is "Illustration of the Method of Burning the House", which shows that the production and use of mirage ash has not been lost since the Zhou Dynasty to the Ming Dynasty, and has a long tradition in Chinese history. time.
