Ji Yuan was surprised: "Isn't the water mill used to grind rice noodles?" ”

Although the water mill can indeed greatly reduce the labor on the rice mill surface, in terms of the value created, it is still not as good as Liulifang, right?

Fu Tinghan: "If the water mill can be successful, then I can make a hydraulic calciner." ”

Ji Yuan looked confused, "What's that?" ”

But when he saw Zhao Hanzhang's eyes brightening, he knew that it was a good thing.

Zhao Hanzhang: "You just have to study with peace of mind, tell me what you need, and I'll let someone get it for you." ”

Fu Tinghan smiled and said: "I know, the water mill was there in the Han Dynasty, in the past, there should be someone in Sinong Temple and the Ministry of Industry who knew the manufacturing method, I just drew a diagram according to the power system, but it may not be correct, and now the water mill is made with a single belt, but I am afraid that the cost will be too high once it is wrong." ”

Ji Yuan: "Ministry of Works? ”

"It's the department responsible for the construction of fortifications," Zhao Hanzhang explained casually, and then said to Fu Tinghan: "Such talents should be in Sinong Temple, Qibu and Water Ministry." ”

The Western Jin Dynasty did not have the so-called Ministry of Industry, and the functions of the Ministry of Industry were scattered, divided into Tian Cao, Qi Department and Water Department, which were under the control of the Winter Palace, and the chief was the chief Sikong.

But Da Sikong is also under the control of Shang Shuling, and it is a coincidence that Zhao Zhongyu is Shang Shuling.

Zhao Hanzhang lowered his eyes and thought for a while and said: "The officials with names and surnames before either followed the emperor to move the capital to Yuncheng, or were killed by Shi Le, but their families may have stayed in Luoyang, I will go back and let people look for it." ”

In this era, knowledge is monopolized, and so are craftsmen.

And some craftsmen, he only knows what to do, but does not know the principle, and the real knowledge is still the scholar officials.

They are not liberal arts students who only read literature as later generations thought, and there are many science students.

Of course, in the two Jin Dynasty, not only liberal arts students were excellent, but philosophers, soldiers, doctors, Mohists, and even astronomers also made outstanding contributions.

These, one counts as one, she wants them all.

The rise of a power should definitely not be only prominent in one aspect, if you want all the people to return to their hearts, it must be inseparable from philosophers and writers, and other families are also indispensable.

Ji Yuan sat quietly on the side, waiting for them to finish speaking before continuing to ask, "Eldest Prince, what is a hydraulic calciner?" ”

Fu Tinghan came back to his senses and explained: "It was used to make steel from wrought iron. ”

He said: "Now we have three iron mines in our hands, and I have sent people out to find new iron mines, and there will only be more and more mines that need to be mined in the future, and now a mine consumes between 3,000 and 8,000 people, and the workers behind the iron mine to smelt iron and steel are more than 8,000, almost nearly 10,000." ”

"And the weapons and armor forged by so many people are not enough to supply the needs of our army, and the efficiency is too low," Fu Tinghan said: "The armor of the Zhao family army led by Han Zhang has the largest coverage rate, and each soldier has three to five pieces of iron in his hand, with an average of 4.3, followed by the Zhao family army led by Erlang, with an average of 3.7. ”

"The Xiliang Army is 3.4, so it seems that everyone has an iron piece to protect important parts, but the Yuzhou Army is only 0.8, and the Zhao Army, if you count ordinary soldiers, it is only 1.2, that is to say, the armor rate is not high."

Ji Yuan was dumbfounded and asked, "When did the eldest prince calculate this data?" ”

"I have always been responsible for the army's combat readiness, and I have always had the data," Fu Tinghan continued to Zhao Hanzhang: "In the final analysis, it is because the efficiency of smelting and forging is too low, people have to lift dozens of catties of sledgehammers to beat iron, and make enough force to forge iron and steel, the best blacksmiths can only beat for half an hour in a row, and people can't swing a hammer continuously for twelve hours a day." ”

Fu Tinghan said: "But water can." ”

He said: "In addition to the forging press, the water power can also be used as a blower, now the temperature required for forging steel is high, the three iron mines where steelmaking is used horses, but there are not enough horses, occasionally people, the damage to the labor is very large, the iron mine over there has even been an incident of workers injured, so I want to try the water drain." ”

His voice was low, "Once the forging press and the water drain are feasible, then there are too many weapons we can make, and the armor can be improved to make it stronger, thinner, and even softer; There is also a crossbow machine that can also be improved......"

Ji Yuan had already shut up, and watched the two of them discuss what to do after the success of the hydraulic calciner, and his lord even looked forward to making every soldier wear full armor, even the horses.

He sneered in his heart, feeling that they were completely foolish dreams, and the girl dared to say this to Fu Gongzi, if she was to change to someone else, who would listen to her say such a dream?

But...... What's going on with good anticipation?

What Fu Tinghan did, it seems that everything has been done.

Ji Yuan thought that several of Zhao Jiajun's golden eggs were all under Fu Tinghan, and his mood couldn't help but surge, in case ...... That's it.

To make a hydraulic calciner, it is necessary to make a water mill first, and then further improve the technology after determining that it is feasible.

Fu Tinghan was right, this water mill is much more important than Liulifang, Ji Yuan also looked serious, and when the two of them finished discussing, he said: "Eldest prince, if you lack anything there, just tell me, and I will do my best to find it for you." ”

Fu Tinghan said with a smile: "There is only a shortage of people, a lack of people who know how to build water mills, craftsmen who are surprised by craftsmanship, and ......."

He glanced at Zhao Hanzhang and said, "There are also talents who are familiar with astronomy." ”

"Astronomy?" Ji Yuan asked curiously, "What does this water mill have to do with astronomy?" ”

Fu Tinghan said slowly: "As far as I know, some astronomical artifacts of this dynasty have also tried to be made with water power, so I think they should know something." ”

"Tai Shi Ling......" Ji Yuan searched in his brain seriously, and said after a while: "If I remember correctly, Tai Shi Ling's name is Li Wen, and it seems that he is not on the list of Shi Le's murders, and he should have followed His Majesty to Yuncheng." ”

Fu Tinghan looked at Zhao Hanzhang.

Zhao Hanzhang thought for a moment and said, "I'll write a letter to my uncle and grandfather in a while." ”

It doesn't matter if you can invite people over, at least you can write a letter to exchange some knowledge, and of course, if you can rob people, oh no, please come over, then it would be better.

Ji Yuan watched Fu Tinghan go down to rest with a smile on his face, and only turned back when he was gone, "The eldest prince is dedicated to doing things, so he doesn't pay much attention to the outside affairs, and naturally he doesn't know the girl's plans, the girl is not angry because the eldest prince ordered Xiao Wei to be killed, right?" ”

"Nope."

Ji Yuan: "I also think that the girl will not be angry, Erlangjun is also generous, and he is close to the eldest son, and he will definitely not go to his heart, but the people around Erlangjun are not necessarily." ”

He said: "The lord humiliated the minister to death, this credit was originally Erlang Jun's, and it was also left by the girl to Erlang Jun for Liwei, the eldest prince suddenly snatched it, and some people were not convinced." ”

"No matter how good a relationship is, it can't resist people's repeated provocations." Ji Yuan sighed and said: "Although the relationship between the old man and the second master was not harmonious, the brotherhood was not shallow, and then Jia Hou repeatedly provoked, which gradually aggravated the dislike, and finally became like that. ”

Zhao Hanzhang was instantly alert, "I know." ”
