The Taishou Mansion was busy, collecting Guanyin soil, sulfur, and limestone, and everyone was very busy, and Sun Jian's 500 personal soldiers completely reached the level of not touching the ground.

What about Sun Quan?

finally figured out how to help Sun Jian solve the difficulties, and when he looked up again, there were no people in the house who were even serving him.

Where have all the people gone?

Puzzled, seeing Wu Jing hurriedly passing by the courtyard gate, Sun Quan shouted repeatedly: "Uncle! ”

Wu Jing stopped, glanced forward, and had to turn around and enter the courtyard to pick up Sun Quan: "Second son, what's wrong?" ”

Sun Quan said in a low voice: "Quan Er has something to ask my uncle for help." ”

"Say." Wu Jing agreed happily.

"Please ask my uncle to prepare something for me...... In Yuelu, outside Changsha City, there is a limestone mine, which annoys my uncle and celebrity to dig ...... There is also a type of stone called kaolinite...... Woo! Woo! Woo! ”

Sun Quan said politely, Wu Jing covered his mouth and hugged him directly into the house.

In the room, Wu Jing put Sun Quan on the couch and asked, "Quan'er, how did you know these things?" ”

"Oops~ What are you doing!" Sun Quan asked loudly, he didn't know why Wu Jing was okay just now, he didn't say a few words, he was like having a convulsion.

"My second son!"

"These things you are talking about are military orders just issued by the lord, and they are strictly ordered not to be leaked, and those who leak them will be cut in half!"

"This is the secret of our Taishou Mansion, how can you shout in the courtyard?"

"Which person in the house owes this to the second son? If my uncle catches him, I have to tear his mouth. Wu Jing pondered for a moment: "No, Quan'er, you can't be alone in the courtyard anymore, from now on, you will follow your uncle to avoid leaking secrets." ”

"Let's go."

Wu Jing stretched out his hand and put Sun Quan on his shoulder, let him wrap his legs around his neck, grasp his hair bun with both hands, and then, as if nothing was going on, hurriedly walked out of the Taishou Mansion.

Outside the city.

Sun Jian's 500 works were all busy, some were grinding limestone and kaolinite with stone grinding, some were digging deep under the soil with less impurities, and some were building kiln mouths, everything was in an orderly process.

"Ce'er."

Sun Jian called out.

Sun Ce next to him responded: "Father." ”

"Unarmour."

Sun Ce didn't move, he couldn't understand Sun Jian's intentions.

Sun Jian explained: "You can't work together as a father, there are too many things to keep an eye on, you are the eldest son in the family, and you will share weal and woe with all the robes on behalf of your father." ”

Huang Gai's eyes widened when he heard this, and he hurriedly reached out to help the apprentice he brought out with his own hands to remove his armor.

The lord is going to train a successor, and you must print your Sun Ce's name in all the merits, so as not to disagree with anyone when you inherit the throne in the future.

Sun Ce hurriedly took off his military uniform and went into battle shirtless, his strong muscles and dark skin were no different from ordinary people, and he rushed into the crowd and worked hard. At that moment, Zu Mao looked at Sun Ce with a smile and said to Sun Jian: "Lord, the eldest prince really has the style you had back then. ”

"Really?" Sun Jian smiled and added, "It's far away." Satisfied, he quipped.

Zu Mao didn't say much more, but changed the topic and said, "Lord, what are you doing with so many people in the wilderness, and you get so many stones. ”

"Da Rong, the reason why the stone merchant dares to be so arrogant is entirely based on the Pang family's many years of experience in burning bricks. The Pang family, the heirloom of poetry and books, recruited brick-burning talents, and began to build the kiln, and the control of the kiln fire was extremely fine, so the green bricks burned out had few pores, strong and durable, which monopolized the supply of stone used by the officials. ”

"But the billet they mop is just the most ordinary kind of soil."

Zu Mao responded: "Yes, experience, it is the Pang family's item, this is a secret that is not passed on. ”

"A secret that is not passed on?" Sun Jian snorted coldly: "Today, Ben Hou will make this secret a joke!" ”

"Do you know why I'm polishing this kaolinite? Because after the kaolinite is ground, it is Guanyin soil, and the mud mixed with Guanyin soil has better viscosity, contains less moisture, and when firing, there are almost no pores, and I don't know how much better than ordinary soil; And the limestone, after two grinding and one burning, finally became cement, which is a sacred object, which can not only stick the bricks, but also block the surface, so that the rain will not invade, and the bricks that repair the city wall will not rot for ten thousand years. ”

"With these two things, do you still want a thousand bricks? From tomorrow, a brand new stone shop will be opened opposite his Pang family's stone shop, and the price will be half of their family's, and the Pang family will be completely squeezed out of Changsha City for me, and see that he will be arrogant in the future! ”

Zu Mao looked at Sun Jian and was stunned for a long time, and even reached out to touch Sun Jian's forehead...... He suspected that his master might have a fever, or why else he would have started talking nonsense?

Can anyone burn this kind of kiln?

Just a temperature, is enough for the master to eat a lifetime, only the talent is very high, can touch the temper of the kiln, the key is that the kiln and the kiln are not the same, there is no master who eats all the kilns in the world, often the new kiln mouth needs a number of masters to study together, in order to understand its habits, which has caused the pottery, brick burning and other processes to be so valuable in this era.

How can the lord talk about this set, which is as simple as eating and drinking?

"My lord, the kiln is ready."

Five hundred soldiers, with the help of old craftsmen, quickly built the kiln.

"My lord, the limestone has been ground to completion."

"My lord, the deep clay excavation is over."

Sun Jian saw that all the preparations were completed, he was overjoyed, and arranged: "Mix the lime powder with the clay, and then grind it into powder again." ”

This is a standard process of two grinding and one firing, and it also solves the process of grinding the limestone finely powdered with rough grinding equipment......

All the tribes completed all this, and the day passed like this, at this time, Wu Jing had just arrived with Sun Quan on his shoulder: "Lord, all the grinding discs and grinding stones in the city have been bought by me, and now they are on the way to be transported, and they will all be delivered soon." ”

"Good!"

With these grinding discs and grinding stones, the small kilns outside the city can be started day and night without stopping, not only for the repair of the city walls, but also for the people in the city.

"This ......"

When Sun Quan saw the scene in front of him, the whole person panicked!

All these processes are very consistent with the history of this period, but the overall process is combined to promote the development of modern civilization in the cement manufacturing industry chain!

Isn't that what I had in mind when I was writing a time-traveling novel?

How did it come true in the hands of Sun Jian!

"Open the kiln!"

The cement after mixing and grinding for the second time was sent into the kiln, and when the kiln fire was ignited, Sun Jian shouted: "Add sulfur and add fire!" ”

At this time, it is not news that sulfur can ignite, and even the marching formation will use this thing to attack the strategy, but no one in the Han Dynasty used sulfur to heat the kiln mouth! In this era, the control of the kiln mouth should not be fired at a slow fire, otherwise, how can you control the temperature at high temperatures? This is a kiln, not a dry pit, and the removal of firewood will never make the kiln mouth cool instantly, and the goods of a kiln will be destroyed if you are not careful, and it is impossible for a businessman to do this.

But Sun Jian did just that!

Not only did he do this, but he also burned the kiln to pitch black, ignoring the smoke that rose from the addition of sulfur.

According to this burning method, no matter what you burn, it must be full of pores, after all, you can't remove the organic matter and water contained in the mud, unless you ......

!

This is, Guanyin soil!

Excellent adhesion, excellent sealing, used to fire ceramics in later generations, Guanyin soil!

The reason why ceramics choose this thing as the main material is that it has good viscosity, and when it is fired, it can almost be so fine that there are no pores, but how did Sun Jian know? Besides, only use Guanyin soil, this thing can't burn bricks, if you want to burn bricks without pores, you have to mix a certain proportion of Guanyin soil into the mud to increase viscosity, this ratio is the ancients spent nearly a thousand years to figure out, how can he know!!!

Turning his head again, Sun Quan really saw that Sun Jian's troops were mixing the soil with Guanyin soil, and then the soldiers who dragged the blank took the mud and dragged the blank into bricks......

Sun Quan rolled his eyes and almost fell off the top of Wu Jing's head, his uncle stretched out his hand, picked him up, hugged him in his arms and said, "Second young master, sleep when you are sleepy, just sleep on your uncle's shoulder, sleep." ”

Sleep ......

Sun Quan can still sleep!
