"It's time to open the kiln!"

An hour later, the kiln mouth was opened, and the soldiers dried the high-temperature kiln mouth for a long time before daring to approach, and slowly hooked out the clinker cement block with a halberd.

Zu Mao approached, looked at the gray thing and asked, "Lord, this is cement?" ”

"That's it!"

Sun Jian had seen in his mind the picture that Sun Quan, who lived in a high-rise building at the time, was typing on a tray into a square box, and put in a similar picture.

"How does this thing work?"

Sun Jian instructed: "Come on, grind it into powder again!" ”

In my impression, Sun Quan, who was reading while typing, said 'two grinding and one burning', but in order to make the clay and limestone powder more evenly mixed, Sun Jian grinded one more time in the middle, and the last time it was a total of three grinding, which was only more fine, and there was no difference from before.

The soldier quickly ground the thing into powder, and then Sun Jian personally went down: "Take water and stir." ”

After the cement was mixed with sand, a hole was dug out in the middle, water was stored in the hole, and then it was stirred into mud little by little.

Sun Jian carried a few stones, took out a handful of mud and smoothed it with his bare hands, and pressed the second one on the water chestnut, so that it pressed back and forth for almost half a meter, and raised the low wall under the gaze of everyone.

"Have you seen them all? This is how it is used, and it is used for bonding, which is much better than the white plaster and mud mixed walls we use today. ”

In the Han Dynasty, there was no cement, and the walls were built with white ash and mud, which was not rice soup at all, so how much rice soup had to be used, and the food was not enough to eat at that time, so how could there be rice soup to build the wall.

Immediately afterwards, he grabbed a large handful of cement and smeared it on the outside of the low wall: "Originally, you should first pour water on the built wall, so that it can evaporate water faster, and then smear the cement on the outside of the wall to ensure that the bricks inside are not eroded by rainwater. ”

"Lord, it's wrong, drying is a fire, and watering is only when it's wet, what you just said is watering and ......drying," Yi Ji added next to him.

Zu Mao was not happy when he heard it: "I said, Mr. Yi, who hasn't made a slip of the tongue?" ”

Seeing that the two were about to quarrel, Sun Jian asked, "Mr. Yi, did I just say watering and drying?" ”

"Exactly."

Sun Jian said with a smile: "That's right, this thing is different from ordinary products, all products are dried by fire, and my cement has to be sprinkled with water, and the more water is sprinkled, the faster it dries." ”

Yi Yuan didn't understand and asked, "The lord said this deliberately for the sake of face?" ”

"You don't believe me?"

Yi: "Of course I don't believe it! ”

"Come on, give the bucket to Mr. Yi." Sun Jian patted Yi Yuan's shoulder: "Sir, the low wall is here, I will order someone to build another one next to it in a while, what about you, just squat here and water it, and see if it dries quickly after watering, or does it dry quickly without watering, can you dare to bet?" ”

"Lord, what are you betting on?"

Sun Jian thought about it for a long time, he really couldn't remember what he wanted from Yi Yuan, so he simply said: "I'll change it for you, you really can't say that word." ”

"Membership, betting."

"What if the lord loses?"

Sun Jian waved his hand: "Including the Taishou Mansion, even the land of the three counties, what do you want?" ”

Zu Mao pursed his lips and glared at Yi Yuan, and said to Sun Jian: "Lord, I will accompany Mr. Yi to guard." ”

"What are you doing with him?" Sun Jian asked.

"Lord, how can you let him keep watering faster than not watering? Could it be that he lost the bet and gave him the land of the three counties that the brothers had fought out by themselves? Isn't that just trying to kill him? Zu Mao himself thought he was very smart and added: "Don't worry, do this kind of dirty work, Mao, I haven't missed it." ”

Sun Jian grabbed Zu Mao's shoulder: "Don't worry, he can't win, you are still useful." ”

After that, he walked over with Zu Mao to the kiln.

"Come on, send all the bricks into the kiln."

The soldiers sent the dragged bricks in, and the reason why he built the Sifang kiln was because the Sifang kiln produced more bricks than the dome kiln, and the lack of capping was the problem of the color of the bricks. The color of the capped kiln will turn blue due to the lack of air circulation, while the non-capped kiln will turn red due to air circulation.

That's all, but, looking at the entire era, no one can jump out of history to understand why.

The mouth of the kiln was resealed, the flame was ignited again, and the moment the sulfur was added to it, the flame was blazing.

Sun Jian squatted in front of the kiln, holding a piece of grass in his mouth and said, "Da Rong." ”

Zu Mao arched his hand: "The last will be." ”

"This burns bricks and cement, but it's our secret, now do you understand why I only let the people close to me and the pro-soldiers participate?"

"My subordinates understand."

"Well, from today onwards, you'll be here for me. The bricks shall be burned for twelve hours, and the fire shall not be weakened, and if the fire is weakened, it shall be filled with sulfur. Tomorrow at this time, I will see the first bricks delivered to the wall of the city, maybe it will be done? ”

"Mao, I will not disgrace my life."

"Good."

Sun Jian thought for a long time and said: "Remember, the five hundred parts are rested in batches, don't exhaust the children, you also need to rest, and give priority to yourself as much as possible without delaying the construction period." Although you are still a strong man, you have also been born and died with Ben Hou for so many years, let's all be middle-aged, and if you don't care about it, it is easy to have problems. ”

Sun Jian remembered a lot of the 'hygiene' common sense he had seen in Sun Quan's use of the box, and even if he didn't understand what hygiene was, he began to worry about the health of his subordinates.

In these years, the soldiers who died directly on the battlefield were far less likely than the number of people who died of injuries and illnesses after being injured, so Sun Jian suddenly felt after seeing those things.

Zu Mao lowered his head, he had never seen the lord so warm, and the emotions between the men flowed freely without saying a word: "Mao Hui, please also take care of the lord." ”

"Let's go, there's still something important waiting for me in the city."

Sun Jian turned around and left, and inexplicably, he saw Sun Quan in Wu Jing's arms and asked, "Why is he here?" ”

Wu Jing is the commander of his own guards, and he received an order to find the stone mill, which is not unusual here, but how could his second son come here?

"Lord......" Wu Jing told everything that had happened.

Sun Jian suddenly remembered the scene in his impression, could it be that his own right also saw these things? Could it be that the strange sound he heard, he had also heard?

Sun Jian was about to ask, but Wu Jing stretched out his hand to dissuade him: "Lord, the second son has been playing on a certain shoulder for a day, he is tired, and he just fell asleep." ”

At this moment, Sun Jian heard a voice that he hadn't heard for a long time......
