Zhao Hao didn't know that his old enemies came to Suzhou from Songjiang to deal with him.

He was pulling Jiang Xueying and Hua Bozhen excitedly to test the effect of building a wall the day before yesterday.

I saw that the wall was completely glued together, and the gray gap between the bricks looked uneven and white frost appeared intermittently.

Zhao Hao took the dagger handed over by Gao Wu and slashed the crack in the bricks. Amid the harsh metal friction, only a shallow scratch on the top.

Then he walked to the wall that had been bonded with tri-corrosion soil and also slashed at the crack of the bricks. With a sneer, the dagger stabbed in two fingers and brought down a large piece of solid tri-corrosion soil.

Hua Bozhen couldn't help but stare at her. These are completely different concepts.

He hurriedly stepped forward and pressed the new mortar solidified in the cracks of the wall with his fingers. It was as strong as a stone. No wonder the sharp dagger could not do anything.

Hua Bozhen pushed the wall hard again, not moving at all.

Then he kicked hard with his feet and pushed hard with his shoulders, but the wall still remained unmoved.

Zhao Hao quickly grabbed Brother Hua, who was in his forties. Why didn’t he care about himself if he was in his forties?

In order to satisfy Hua Bozhen's obsession, Zhao Hao asked Gao Wu to find a hammer and swung it hard for a few times before he smashed a big hole in the solid brick wall.

As for the wall bonded with three-piece soil, Gao Wu achieved the same effect with just one hammer... This is why the city wall must be thick enough.

"The intensity needs to be improved." In this way, Zhao Hao was still a little dissatisfied.

"The time is still short." Yu Ben whispered: "Young Master, Jiangnan is too tide, I'm afraid I have to wait three days to achieve the same effect in Beijing."

When Hua Bozhen heard this, he thought to himself that he had been studying this thing for a long time.

"It's not just a matter of time." Zhao Hao frowned and said, "You also have to adjust the formula. Next time you try adding some iron powder."

"Yes, young master." Yu rushed and responded in a deep voice.

"The glutinous rice mortar is just like this. Do you think it's not strong enough?" After Yu Ben retreated, Hua Bozhen couldn't help but say shocked: "This is to be strong enough. Then don't even think about demolishing the house you built in the future."

"Hahaha, that's true." Zhao Hao laughed and said, "This kind of cement is indeed enough for building a house. But I need to strengthen it if I want to use it to build a dam."

"This thing is called cement?" Hua Bozhen said in front of his eyes: "'The smoke opens the green fan and the breeze is clear, and the cement red clothes are white dew autumn'. What an elegant name."

Zhao Hao was so angry that he was really a literati who could arrange it. This was the first time he heard that the name of cement was elegant.

"Brother, can cement really replace glutinous rice mortar?" Jiang Xueying, who had been quiet, asked softly.

She knew that there are currently two types of mortars used to bond masonry and stone, the commonly used sanhe earth mortar and the glutinous rice mortar with excellent performance.

But the former is limited in strength, while the latter is too expensive...

A new section of the city wall was built the Suzhou city wall the year before yesterday, which was originally built with glutinous rice mortar. However, after only two miles of construction, a total of 100,000 kilograms of glutinous rice were consumed.

Even the wealthy Suzhou Prefecture could not afford it, so it had to return to the mortar of Sanhedi.

So if you want to use glutinous rice mortar to build the dike, even the wealthy Mr. Zhao could not afford it.

Besides, there are not so many glutinous rice available.

"It can completely replace glutinous rice mortar, and with the improvement of the formula, the performance will surpass it." Zhao Hao said confidently: "And it can harden in water, which is unmatched by glutinous rice mortar."

"Wouldn't you be able to build any dam as long as you want?" Jiang Xueying's beautiful eyes also emitted an excitement.

"Of course." Zhao Hao nodded proudly: "With this thing, I can build a dam for the entire Kunshan!"

~~

Zhao Hao’s confidence comes from this Xishan Island.

On this magical island, limestone is rich in high-purity cement, and it is accompanied by a considerable amount of gypsum - these two, together with clay, are the three main materials for firing cement.

But Zhao Hao did not use clay, but used the kaolin that was abundant on the island. Because the purpose of calcining clay was to obtain kaolin. Therefore, this step directly saves time and saves a lot.

There are enough open-pit coal mines on the island - replacing wood with coal as the main fuel for calcining cement, which can shorten the calcination time from seven days to two days.

Even another important ingredient for cement - iron powder or iron slag. However, Mr. Zhao has not found a location for pyrite yet...

It’s amazing that you can reduce high-quality cement without leaving the island!

Mr. Zhao wanted to change the name of Xishan Island to "Cement Island". Fortunately, he was a literati, so he finally resisted burning the piano and boiling the crane.

He lowered his voice and said to the two: "Now you know, our Jiangnan company, what should we do next?"

"Build the embankment! Build the embankment! Build the embankment!" Hua Bozhen was excited and said the important things three times.

Jiang Xueying couldn't help but feel excited: "If we could easily build an indestructible embankment, the entire Jiangnan pattern would be changed!"

"Not bad." Zhao Hao nodded with a smile: "This inconspicuous cement was born to change the shape of this world!"

"Good brother, you must leave this job to me!" Hua Bozhen grabbed Zhao Hao's arm tightly and begged almost.

"As long as the eldest brother can go, the company will certainly beg for it." Zhao Hao nodded with a smile.

"No problem, I will make arrangements." Hua Bozhen was so happy to get Zhao Hao's approval. He approached the brick wall with a big hole, and while stroking the rough cement in the cracks of the bricks, he said happily: "Brother, I leave my name in history, rely on this cement!"

Zhao Hao couldn't help but look at him with admiration. Unexpectedly, the eldest brother of the Hua family had a very sharp vision and could foresee the greatness of this invention at once.

"It's too far away to leave a name in history. Let's make some money now." Zhao Hao smiled and said to Jiang Xueying: "I must have thought of what to do."

"With a cement invented by my brother, my younger sister suddenly thought of more than a dozen ways to make money." Jiang Xueying smiled and said, "But there is no hurry for anything else. However, I think we should start immediately and acquire some land that is about to be completely changed by the cement dam in advance."

As she said that, she whispered: "This is a reference to my brother's approach in Xishan Company."

"Hahaha, I think so too." Zhao Hao nodded with a smile, then smiled and said, "But one of them please forgive me. Jiangnan Company only rents the land in Kunshan and does not buy it."

"This is natural. Ling Zun is in charge of Kunshan and it is really not good to buy land for our company." Hua Bozhen smiled with understanding.

"Of course they all depend on your elder brother." Jiang Xueying was naturally even more troublesome. "What about the other county?"

"No restrictions were set." Zhao Hao smiled and said, "I see that there are large mudflats east of the Huangpu River. We might as well eat that section first before talking about it elsewhere."

"Okay, if your brother doesn't dislike it, let me leave this matter to my younger sister." Jiang Xueying volunteered.

"Then the relationship is good!" Zhao Hao was so happy. "This person who is not familiar with the place is worried about who will take care of this matter."

"I will do my best to do my mission." Jiang Xueying Yingying's elegant demeanor.
