Metallurgical Division.

"Your Highness, this person is the old craftsman that the lower officials said."

Wu Zhihua pointed to a craftsman standing stiffly on the side and said.

"Your Highness, little ......, little official Qian Yuan, meet Your Highness."

The old craftsman Qian Yuan looked very nervous, and when he heard that he was mentioned, he hurriedly knelt down and saluted, and stammered.

Ji Yu was secretly amused when he heard it, it turned out that most of the people he met saw him, and they either called themselves villains or self-proclaimed officials, and this self-proclaimed petty official was the first time.

However, this also shows that this person has been honest and honest all his life, and he has never seen any big officials, so he has a gaffe.

Ji Yu's face did not move, and he said in a gentle voice: "Hurry up and be polite, Master Qian, you have developed a new type of material?" ”

Qian Yuan was stunned when he heard this, the material? What is Material?

Wu Zhihua saw Qian Yuan stunned at Ji Yu, and reminded anxiously: "Old Qian, Your Highness asks you!" ”

"Oh oh, that is, it is a sticky thing made by the villain unintentionally, but after drying, it is very hard, and it can't be cut with a kitchen knife!"

Qian Yuan came back to his senses, and when he talked about the results he made, he was still confused.

"Sure enough!" Ji Yu said secretly, and then said to Qian Yuan: "Then this thing, how did you make it!" ”

When it comes to the process, Qian Yuan is not nervous anymore, and he talks about the process smoothly.

"Back to Your Highness, it's like this! Recently, our smelting and manufacturing department has been making this honeycomb coal, and then I heard Lord Si Cheng say that if a new technology is developed, the silver will be rewarded, and the big guys are thinking about whether they can improve this honeycomb coal again. I'm at home, and I'm trying. ”

"I wondered if I could use less coal and more other worthless alternatives to coal, so I tried a lot of things, but it didn't work."

"Later, when I tried to come to Shiraishi, it was not the same as before. I grinded the white stone into powder, added clay surface, and a little cinder, and added water, and put it in the furnace, and the things that came out could not be burned. I thought it was a failure, and I thought about adding more cinders this time to try, but when I added water, I accidentally poured the water on top of the powder, and when I stepped on it, it felt sticky, and I didn't take it seriously at the time, because I also added clay! Just try the next time. ”

"After a while, the mud on my feet hardened, and I threw my shoes into the water, thinking about it for a while, and it melted away. When I look at it again, it's still what it was like at that time, and it's not soft at all! I tried several more things, but I couldn't get the hardened mud off my shoes. ”

"I wondered, is this also a new kind of craft, if you think about it, if you paste it on the shield, the armor, will it work? The more I think about it, the more I can do it, so I came to find our Si Cheng, Lord Wu! ”

After speaking, he looked at Wu Zhihua and Ji Yu cautiously.

After Wu Zhihua listened, he turned to look at Ji Yu, "Your Highness, look at ......"

Ji Yu didn't expect that the birth of the world's first cement was so coincidental, and it was related to another thing he brought———— honeycomb coal. I can't help but feel that creation makes people.

"When that thing solidifies, does it sink? If it is used on the soldiers, will it make the soldiers feel uncomfortable? ”

Ji Yu asked.

"Ahh I forgot about it! That thing is really heavy, and it can catch up with the iron block! ”

Qian Yuan slapped his thigh and said with great annoyance.

"Old money, old money, why don't you figure it out and come again, delaying Your Highness's precious time!" Wu Zhihua said to Qian Yuan.

Ji Yu hurriedly stopped Wu Zhihua, "It's okay, this thing, maybe it's still useful?" ”

He asked Qian Yuan again: "What kind of thing is that white stone, do we have it here now?" ”

"Yes, there are in the shed. I'll go and bring it to Your Highness. ”

With that, he turned and trotted out the door.

Wu Zhihua was puzzled, what is there to see about Baishi? That's a lot of stuff! But he didn't dare to refute Ji Yu, so he had to look at Qian Yuan's figure going out, secretly thinking about what use this thing would be.

After a while, Qian Yuan came in with a white stone.

"Pop" fell to the ground, shattered a few small pieces, and flew to the ground.

"Your Highness, this is it!"

Ji Yu took two steps forward, squatted down, looked at the white stone carefully, reached out and touched it again, and saw the white marks on his hand, Ji Yu was sure in his heart, "It's you, limestone!" ”

"Good! Qian Yuan, this thing is really useful! You've done a great job this time! ”

"Wu Zhihua, take out a hundred taels of silver to reward Qian Yuan!"

Ji Yu said excitedly to the two.

Qian Yuan was taken aback when he heard this, "Ah! Then he said in a panic: "Your Highness, no, no, this is not a useful thing!" ”

Ji Yu laughed dumbly when he heard this, and before he could speak, he heard Wu Zhihua reprimand loudly.

"Be bold, Your Highness will definitely be of great use if you say it is useful, you dare to question Your Highness's words!"

When Qian Yuan heard this, his face was frightened, and he was about to kneel. said in his mouth: "This is not what the villain meant, not this!" ”

Ji Yu hurriedly stopped Qian Yuan's movements and glanced at Wu Zhihua.

Wu Zhihua is not afraid, these days, he has already figured out Ji Yu's temper, as long as he does not touch His Highness's bottom line and does not deliberately make trouble for His Highness, this Fifth Highness is a very good talker, so good at talking that he does not look like a prince.

So he asked with a smile: "Your Highness, forgive your official for being stupid, I really can't figure out what use this thing will be!" ”

Ji Yu patiently explained: "You said that this thing is extremely hard after drying, and it can't be broken by a knife, so can it withstand wind and rain?" ”

Wu Zhihua and Qian Yuan nodded.

Ji Yu continued: "If it is paved on the ground, is it a road that is not afraid of the sun and does not shoot the rain. ”

Wu Zhihua seemed to understand a little, "Your Highness wants to use it to build roads?" ”

Ji Yu nodded and continued: "If you use it to build a pipeline from the capital to all parts of the Great Zhou, how many silver taels will you save!" ”

Wu Zhihua suddenly realized that the materials for this thing are very cheap, white stone, clay, ...... It's almost all over the ground. Moreover, the road is smooth and hard, which saves the need for annual repairs. It will indeed save a lot of money!

"So, Qian Yuan, you have made a great contribution to my Great Zhou, you can accept this one hundred taels with peace of mind!"

Ji Yu's words changed and said to Qian Yuan.

"Yes, yes. Thank you, Your Highness, for your kindness! ”

Qian Yuan's eyes flashed with crystal, and he thanked Ji Yu.

One hundred taels! Even Wu Zhihua was a little envious of this lucky guy.

You must know that in the Great Zhou, an ordinary family of four can pay for a month's expenses with one tael of silver, and Wu Zhihua, as a four-grade official of the imperial court, only has forty taels a year. But this money was rewarded with a hundred taels of silver at a time, which is Wu Zhihua's two and a half years of money!

"Try adding some scrap iron slag to this thing and see if it will be harder."

Ji Yu recalled the method of making cement, but he didn't know about this thing, he just listened to what others said, and he listened to it himself, and he didn't know if it was true or not, so he could only let the craftsmen try more!

"Yes. Your Highness, this thing doesn't have a name yet, so why don't you get one! ”

Wu Zhihua said flatteringly.

"Let's call it cement!"

Ji Yu said casually.

"Good! It is thick when exposed to water, and air-dried and hard. Cement, good name! Your Highness is a great talent! Wu Zhihua was taken aback.

Ji Yu looked at Wu Zhihua helplessly, this can also be forcibly patted on the back, you are really a ...... Talent!
