Ren Ruqing was beaming with joy, holding a burden in his arms, only to get up as if it was a little difficult, put the burden aside and bowed to Li Qingxian, and then arched his hand towards Lu Yiming, and said: "Lord, there is indeed a new thing, which was inadvertently estimated by the craftsmen, and I think it will be useful, so I will bring it to the lord to appreciate it." Pen %Fun %Pavilion www.biquge.info"

Li Qing looked at the tightly wrapped baggage, and said with a smile: "You guys have made something new again, hurry up and open it, don't you see that Lord Lu's neck is stretched so long......"

Several people laughed, Ren Ruqing bent down to untie the wrapper, Lu Yiming looked at it fixedly, but it was a camel gray stone, but it was boxy, sharp and angular, and couldn't help laughing: "I said Lord Ren, what are you doing with a stone, even if you cut him neatly, he is still a stone, could it be that there is a precious original jade hidden in it?" ”

Ren Ruqing said proudly: "I know that Lord Lu doesn't understand, and he will definitely think that this is a stone, lord?" Ren Ruqing looked at Li Qing.

"Do you want to test me?" Li Qing laughed, stretched out his hand and hugged this angular stone, in fact, the moment Ren Ruqing opened the furoshi, Li Qing's heart jumped, at that moment he already recognized this thing, what kind of stone is this, it is clearly the most common cement block in the previous life, cement, Ren Ruqing They actually made cement!

"Did this thing be made by some powdered stuff, mixed it with sand, mixed with water, and then it became this thing after it solidified?" Li Qing looked at Ren Ruqing.

Ren Ruqing's eyes slowly widened, his mouth opened into a 0 shape, and the smile on his face slowly faded, replaced by a look of surprise, "Lord, how do you know that this is the case?" I've also just learned about it. The craftsman who made it didn't realize he had found something remarkable.

I didn't report it at all, and I found out occasionally. ”

Li Qing had an unfathomable smile on his face, but he didn't say anything. Just holding the cement block and looking over and over again, Lu Yiming gloated and smiled: "Lord Ren, it's okay if you want to stump me, you actually want to stump the lord, isn't that self-inflicted, the lord is a pedantic man, what is there in this world that the lord doesn't know?" ”

Ren Ruqing nodded again and again, with a look of admiration. Then he picked up a box from the furoshiki and contained some very fine gray powder, "My lord, this is the ingredient for making this thing!" ”

Looking at these powders, Li Qing couldn't recognize them, "What kind of raw materials are these, how did you get them?" ”

Ren Ruqing said: "Lord, isn't the First Military Factory researching Shenwei cannons?" In the process of continuous testing, due to the excessive power of the Shenwei cannon, the recoil is too strong, each launch will be the mound of the fort to disperse and loosen, the craftsmen have to rebuild the fort every time they put a few guns, it is very troublesome, so there are several craftsmen to make a stronger fort after repeated trials, and then come up with such a wait, I asked them carefully, this thing is made of limestone, clay as raw materials, it is crushed into a very fine powder, and then add some gypsum powder to it, and it is done. You also know that we have a lot of limestone here, and there is no shortage of clay, although there is not much gypsum powder, but the amount is not large, but it can be used in large quantities to make this thing, I thought, the fort made of this thing can not even be destroyed by the Shenwei cannon, so use him to build a house, make a city wall, ordinary trebuchets can not destroy it at all, so I hurriedly ran to show the lord. ”

Li Qing smiled: "Yes, yes, sure enough, some great inventions are all made by some lazy guys!" ”

Ren Ruqing was taken aback when he heard this, "Lord, those craftsmen are very diligent, and they are by no means lazy people!" ”

Li Qing laughed, and Lu Yiming was also Wu'er, "Lord Ren, the lord is complimenting them, what is the name of this thing, is the arsenal named?" ”

"No, don't you want to ask the lord to come up with a name?" Ren Ruqingdao.

"You're going to please me!" Li Qing said with a smile: "This thing condenses when it encounters water, so it's called cement!" ”

"Cement?" Ren Ruqing was a little dissatisfied, this name was too ordinary, it was as loud as a Shenwei cannon, but since the lord had spoken, it was the final word, and he could only nod and nod, "Okay, this thing will be called cement in the future, lord, can I order the arsenal to make this kind of cement in large quantities?" ”

Lu Yiming interjected: "Wait, Lord Ren, is this thing really simple to make and extremely strong?" ”

Ren Ruqing was displeased, "Lord Lu, if this is not the case, do I dare to bring it to the lord?" ”

"Can you give it a try, let me see it for myself!" Lu Yiming insisted.

Li Qing smiled slightly, "Li Wen, you come in!" ”

Li Wen entered in response, "My lord! ”

"You get a hammer and try Lord Ren's new gadgets, can you convince Lord Lu!"

After a while, Li Wen had already brought a hammer over, threw the cement block on the ground, and knocked it down with a random hammer, when it sounded, Li Wen snorted, the cement block actually only appeared a few cracks, you must know that although Li Wen didn't use much strength, but this hammer is the weapon of a guard in the guards, and its own weight is dozens of their own hammer down, less to say that there are hundreds of pounds, the imagination should be broken in response to the sound, and the destruction of the thought is that in front of the lord made a fool, I can't help but blush, with full strength, With a loud cry, a hammer knocked down, but this time, the cement block was hammered into several large pieces and fell to the ground in pieces.

"Good guy, hard enough!" Li Wen was speechless, "Compared to ordinary stones, it is much harder!" ”

Ren Ruqing looked at Lu Yiming proudly, "Lord Lu, how is it, this is what General Li said, not that I am boasting!" ”

Lu Yiming didn't have a smile on his face, "Lord Ren, could you please demonstrate how this thing is made again?" ”

Seeing that Lu Yiming was still tireless, Ren Ruqing snorted and said to Li Wen: "General Li, please get some water and sand!" ”

Li Wen smiled and nodded, he was also very curious, turned around and went out to recruit a few guards, whispered a few words, several guards immediately flew away, and after a while, he carried a bucket of water and half a bag of sand to the door.

A few people went out, but the sun was scorching outside, very roasting, Ren Ruqing strode into the sun, poured some sand on the ground first, and then poured the cement in the box into it, and hummed with water, Li Qing hugged his arms, stood under the eaves with a smile, and watched Ren Ruqing tinkering there.

Ren Ruqing mixed it evenly, then mixed it with water, and mixed it over and over again, and randomly kneaded the mixture on the ground into a square with his hands and placed it under the sun.

Everyone looked at the gray thing, Li Qing smiled and said, "Lord Ren, wash your hands first, he wants to solidify, it will take a while, let's go have a cup of tea first, okay?" ”

Back in the house, Li Wen ordered to make tea for Ren Ruqing, and changed a cup for Li Qing and Lu Yiming, and everyone drank tea while waiting for the cement to solidify.

"Lord Ren, have you ever thought about mixing this cement with steel, well, I mean, you can ask Xu Xiaodao to pull the steel into a thin iron rod, and then insert it into this cement, oh, by the way, this cement is mixed with sand, and you have to add some stones, and pour it with steel, will it be stronger?" Li Qing said with a smile while drinking tea.

"So?" Ren Ruqing tilted his head and thought for a moment, then suddenly jumped up and said to Li Qing: "Lord, this method is too good, if you do it like this, General Li will not be so easy to break it just now." ”

Li Wen smiled: "It's not easy! Li Wen did not tell a lie, with his great merit, he wielded the sledgehammer and hammered it down with all his might, at least with a force of several hundred catties, and did not knock the cement block into pieces, but only broke into several large pieces, which is indeed stronger than ordinary stones.

Ren Ruqing stopped talking, fell into deep thought, obviously thinking about Shiqing's suggestion, everyone in the room had their own thoughts, and it was quiet for a while.

About half an hour later, Li Qing stood up and said: This day, it should be almost over, let's go and have a look! “

When everyone walked out of the house and looked at the cement block, it had become almost the same color as the square that Ren Ruqing had taken out before, and under the scorching sun, there was little moisture outside.

Li Wen walked over and picked it up, held it high, let go, and the cement block fell to the ground, but it did not crack, it was still the same as before.

"My lord, if he is to reach the strength of the cement block before, it will take at least a day under this kind of sun, because the outside is easy to dry, but the water inside is not completely dry."

Li Qing nodded, "Master Lu, believe it this time!" ”

Looking at the cement block on the ground, Lu Yiming turned around and faced Li Qing, "Lord, I suggest that this thing not only cannot be manufactured on a large scale now, but also must be kept strictly secret and must not be leaked at all." ”

Ren Ruqing jumped up, "Why is this?" ”

Lu Yiming said: "Lord Ren, if the manufacture of this thing is really as simple as you say, then it is very easy for others to imitate, just know the manufacturing method, anyone can make it on a large scale, think about it, if this thing is known by Luoyang to refine the method, use it to strengthen the city wall, build a fortress, how convenient, it is easier than collecting stones, and the stones are difficult to transport, but this thing is much simpler." This will cause great hardship to our soldiers on the front line, and will cause more casualties when we attack some cities in the future. ”

"This?" Ren Ruqing was speechless for a while.

Lu Yiming's words made Li Qing also frightened, Lu Yiming said well, this thing does not have any core technology, just know what the raw materials are, it is very easy to imitate.

"A whistle is reasonable!" Li Qing said in a deep voice: "Cement is indeed useful, but now it can't be manufactured on a large scale, so let's do it, Ruqing, the craftsmen who invented this thing are all awarded officials, as for secrecy, you will explain to them, you can make some in small quantities in the arsenal, and transport them to the front line to build fortresses, but transportation, construction must be carried out by fixed people, let the Supervision Yuan be responsible for secrecy work." ”

"Yes, Ruqing understands!"

"Cement is a good thing!" Li Qing said with a smile: "When the overall situation of our war with Luoyang is decided, it can be manufactured on a large scale, used to pave roads, build bridges, and build houses. ”
