'Bang! Bang! Bang!'

Pan Jixun used all his strength to smash it a few more times, but it still only knocked off some powder and gravel.

He finally confirmed that this pile of small stones was no different from a big stone.

"Huh..." Pan Zhongcheng threw away the hammer, stretched his numb arms, and walked forward to carefully study the lump of stone.

He picked up the powder on the ground and examined it carefully, and even tasted it...

Young Master Zhao was stunned. How the hell can this be eaten?

"There is no glutinous rice, no egg white, what material did you use to make it so strong?" Pan Jixun looked back at Zhao Hao, the white ash at the corners of his mouth could not hide his desire for knowledge.

"You can taste this?" Young Master Zhao opened his mouth wide. Is this a mouth or a chemical analyzer?

"I can only taste it. You used slaked lime, sand, and gypsum..." Pan Zhongcheng savored the taste in his mouth. A little uncertain, he lay on the lump and licked it again.

"It seems to have a faint smell of iron..."

It's a wolf extermination.

A capital "服" emerged in Zhao Hao's mind, and he suddenly had the urge to keep Lao Pan'er in captivity and make him serve as a human analyzer.

In this way, the chemical industry of the Ming Dynasty could start at least ten years earlier.

Fortunately, Old Pan'er was a dignified third-rank Right Vice-Censor-in-Chief and could not be listed as a missing person without a trace, which dispelled Master Zhao's evil thoughts.

Pan Zhongcheng, who didn't know he was about to lose his freedom, still asked like a big curious baby: "What else did you add? Is it expensive? How long did it take to become like this?"

"Cement, our own cement is not valuable. It has been three days since it was made." Zhao Hao smiled and said, "Isn't the Minister in a hurry to go home? I won't delay your journey. If you hurry up, you may be able to get home before dark."

"You!" Pan Jixun was furious and was about to swear at me again.

But he was really interested in that "cement" that Zhao Hao talked about.

Pan Zhongcheng's expression changed several times, but he finally softened his posture and said with a wry smile: "You kid, when did I say I was leaving?"

He quickly signaled to the servant with his eyes to move the luggage back quickly.

"Am I the kind of person who starts off well but ends badly? I said I would help the people of Kunshan fight the flood, so I will definitely stick with it until the storm is over."

"Forget it. You are too angry, old man, and I am afraid of it as a child." Young Master Zhao still shook his head.

"You!" Pan Jixun's blood boiled, but he suppressed his temper under the pressure of the cement, and forced a smile, saying, "Okay, I promise not to lose my temper again, is that okay?"

"What if you don't keep your promise?" Young Master Zhao asked childishly.

"What do you think we should do?" Pan Jixun felt like he was about to explode.

"You have to promise that every time you get angry, you will stay here for one more month." Zhao Hao said seriously.

"Uh..." Pan Jixun was speechless and could not nod.

Zhao Shouzheng was also secretly worried for Old Pan. He thought, given your temper, if you really agree, just change your registered permanent residence to Kunshan County.

"See, I knew that you didn't keep your word." Zhao Hao turned his head and pretended to leave.

"Don't go, don't go." Pan Jixun had no choice but to hold Zhao Hao and said, "Isn't it enough that I promised you?"

After a pause, he pointed at the pile of stones and said, "As long as the cement is as magical as you say, I guarantee that it will last for an extra month after each flare-up, until it is exhausted. Is that ok?"

"Okay, that's okay." Zhao Hao finally nodded, and the two of them even made a pinky promise like kids.

Master Zhao then stopped his malicious act and took Pan down the levee.

Without the obstruction of the dam, Pan Jixun was able to see that there were ten large ships coming with Master Zhao.

Zhao Hao nodded, and Yu Ben ordered his men to lift the oilcloth covering the boat.

The first boat was piled high with dirty sacks, while the next nine boats were filled with rough stones.

By the way, these ten boats all came to Kunming with Master Zhao yesterday.

In other words, half of the cargo on the ship that Young Master Zhao brought yesterday was not food.

That's why he was so aggressive from the start and incited the people to attack Inspector Lin and the Xu family's servants.

He was really worried that if Inspector Lin found out that his boat was half loaded with stones and half with grain, it would be like yellow mud falling into his crotch, and he would get into trouble.

Fortunately, Lin Xun'an collapsed, which made Zhao Haobai worry.

The workers carried the sacks off the boat and piled them on the open space by the river.

Zhao Hao asked someone to open a bag and show it to Pan Jixun.

"So thin, like fried noodles?" Pan grabbed a handful and looked at it carefully.

Just as Pan Jixun was about to taste it, Zhao Hao quickly grabbed him.

"This stuff will react when it comes into contact with water. If you don't want to get your throat stuck, just eat it."

"Uh..." Pan Jixun hesitated for a moment, and finally resisted the pica hidden deep in his heart. He clapped his hands and said, "How do I use this cement?"

"Just watch." Master Zhao smiled and asked Yu Ben to demonstrate to Pan Shen'er.

Yu Ben ordered people to open a few bags of cement, and then take river sand and gravel directly from the river, mix them in a ratio of roughly one to one to three, add one-third of water to the amount of cement, and stir it on the spot with a wooden stick.

"Can gravel be used?" Pan Jixun's eyes widened again.

When he was building the river embankment, he hated gravel because too much gravel would cause the embankment to leak.

However, those disobedient workers refused to sift the soil and filled the dike with soil and stones. As a result, the dike was destroyed by a hole, which affected the entire dike.

Of course, there are too many stones by the river...

Seeing that Zhao Hao used gravel the most, Pan Jixun became even more interested. He thought that the consumption of cement and stone was much less than he had imagined.

While the workers were stirring the mixture, Zhao Hao had someone dig a coffin-board-sized trench on the ground as the foundation.

Once the trench is dug and the concrete is mixed.

He asked Yu Ben to first lay a half-foot thick layer of concrete at the bottom of the trough as a base, and then lay rough stones of various shapes on it.

When the rough stone is inserted into the concrete about halfway, pour the concrete. After filling all the gaps, lay the rough stone and pour the concrete layer by layer.

As the wall was raised layer by layer, an ugly, uneven wall appeared in front of everyone.

Finally, fill the gaps with mortar and small stones to ensure that the stones are completely surrounded by concrete.

Well, it looks much better.

The whole process does not require any professional bricklayers, nor does it involve any technical content. It is just a matter of combining the odd-shaped, large and small rough stones and putting them together as flat as possible.

From laying concrete to building the entire wall, it only took a meal to complete.

Pan Jixun's pores were bursting with sweat after seeing this!

If the stone embankment was built normally, in such a short time, I'm afraid that even the holes in the stones wouldn't have been drilled properly.

Not to mention how long it would take to chisel a stone slab that meets the specifications.

What kind of speed is this?

This is flying speed!

Building a stone embankment every month does not seem impossible.
