Cai Xianggong's servants were wrapped into meat buns. Yun Chao shook his head after hearing this.
This matter is caused by trouble, just wait, maybe Cai Xianggong will remember it in a few months and send someone over.
These days, communication is inconvenient, and transportation is even more inconvenient. When sending people out to do things, even if they are as powerful as the prime minister, they still have to be patient and wait.
It’s normal to have feedback within a month or two, and it’s not unusual for someone to not go back for three or four months.
Yun Chao can put Xianggong Cai aside for the time being, at least it won't be too late to talk about what will happen in a few months at least.
Wu Er is back, Yun Chao can rest assured.
Someone from Wolong Village came to report that the coke furnace and earthen blast furnace had been built. The craftsmen asked him if he wanted to go back for inspection.
Anyway, there is nothing important to do in the city now, so Yun Chao simply rushed back to Wolong Village.
The principle of the earth coke oven is very simple. Coal is placed in a closed furnace, a small part of the coal is ignited, and the entire furnace is sealed. The heat released by the coal's own combustion is used to heat and retort the coal in the coke oven.
Yun Chao just explained the general principles, and a few potters built the coke oven, and it was qualified the first time without the need for rework.
"Load the coal. Start testing now. Pay attention to the amount of coal loaded in each coke oven and try to find the best method in a short time."
"yes!"
After watching coking, Yun Chao went to see the earthen blast furnace built by Tang Long.
This is not difficult, the technical content is not high, it is like a layer of film, which can be broken with just one poke.
Yun Chao just nudged it a little, and Tang Long understood the principle.
It's nothing more than building a circulating heating device.
The rest of the structure, such as adding materials on top and discharging molten iron below, was not difficult for Tang Long at all.
Unfortunately, the coke has not been burned out yet, so ironmaking will have to wait for a while.
Yun Chao checked it roughly and found no obvious flaws.
"Lao Tang, build another crucible furnace. Once high-quality pig iron is smelted, we will start making steel immediately."
"yes!"
As a blacksmith who pursues technology, Tang Long did not discount Yun Chao's instructions at all.
To have such a tyrannical financial sponsor as Yun Chao offer him money to conduct research, only a fool would refuse.
In fact, Yun Chao is just giving some guidance on the general direction. A doctoral student from the Agricultural University can be asked to farm, and he can be asked to make coking and steel. It would be good to know the general direction.
After seeing the blast furnace, Yun Chao went to see the earthworm farm.
The helper who cultivated earthworms was very excited and said that the method provided by Yunchao was very easy to use and the earthworms were growing well.
Breeding is Yunchao's specialty.
Even if Yun Chao has not specifically studied raising earthworms, he can still speak clearly.
Just by looking around, I found several shortcomings.
After some guidance, all the helpers were sweating coldly.
As expected of a super guy, just by casually looking around, I can tell what everyone does and what bad habits they have!
Then, Yunchao went to the chicken farm again.
Hearing that the big hen he bought had begun to lay eggs, Yun Chao asked someone to cook one for him, and he thought it tasted pretty good.
Seeing Yun Chao eating well, the chicken helpers all felt happy in their faces.
Yun Chao went to see dozens of hens that were hatching eggs. Although the method of introducing nests has greatly improved the hens' nesting rate, this method is still too backward. At this rate of development, when will it be possible? Tens of thousands of chickens?
Pig farm, duck farm...
Yun Chao turned around and found many things that were not in place.
However, overall, Yun Chao is quite satisfied.
After all, the helpers responsible for breeding are all people with little education, and most of them have never done breeding. It is really unrealistic to expect them to reach the level of technicians in future generations all at once.
We can only learn slowly and sum up experience slowly.
With nothing to do, Yun Chao started tinkering with biological feed.
Whether it is chickens, ducks, pigs or geese, biological feed can greatly increase their growth rate.
The method of making biological feed is very simple. The only difficulty is that Dawu Dynasty does not have biological starter.
However, this is not a problem for Yunchao. He needs to get a few more organic substances, mix them for fermentation in different proportions, and test a few more times to get a relatively stable fermentation strain. The process is similar to making an old starter.
Yun Chao had tinkered with the biological starter in his previous life and made it within a few days.
In order to improve the nutritional content of the biological feed, Yunchao also used a hydraulic device driven by a large water truck to crush the bones left behind when eating meat and added it to the biological feed.
In fact, the waterwheel is carrying a big hammer, banging, banging, banging, and then carrying a big millstone, grinding hard.
Under the guidance and inspiration of Yun Chao, the craftsmen have now come up with many new tricks on the waterwheel.
Such as water-powered mills, water-powered forging hammers, etc.
Yun Chao has arranged for craftsmen to study the firing of cement.
However, making cement is not Yun Chao's specialty. He only knows the general direction but does not know the specific formula. He can only let the craftsmen slowly explore, so no real cement has been burned yet.
If you want to get some tech tree points, you can’t be in a hurry.
If you can produce results in a year and a half, you are already very good. If you want to develop a light, telephone, radio, and a large airplane in a short period of time, let alone Yun Chao, a quasi-doctorate from the Agricultural University, it will not be possible even if you have two senior academicians. !
While Yun Chao was busy doing scientific research, Li Xing suddenly returned from Qingyang County.
"Brother Chao, someone contacted that Xiaohong..."
"oh?"
Yun Chao perked up: "Is the mastermind finally taking action?"
Li Xing was very excited, because an accident occurred while stalking Bald Jiang, resulting in one death and one injury, which made him blame himself. Therefore, Li Xing is now focused on Xiao Hong, trying to regain face and face from her. Return confidence.
Unexpectedly, Xiaohong entered the back kitchen of Lion House, and no one contacted her for such a long time. Li Xing thought that the other party had given up, but he didn't expect that she would actually come.
"Brother Chao, don't worry, I will do things beautifully this time. If there is another accident, you will chop off my head!"
Yun Chao glanced sideways at Li Xing: "I'll cut it off, what's the use of your head? You have to keep a normal mind, keep a normal mind, you know? How do I usually teach you? It's been so long, and you still haven't recovered from the setbacks. When you come out, do you want to be like Zhang Sihai and work in the field?"
"No no no..."
Li Xing was so frightened that his legs went numb.
"Brother Chao, please don't let me go out on the field. I will definitely be able to keep a calm mind. Just take care of it!"
Yun Chao waved his hand: "Stop talking nonsense. After talking for a long time, you still haven't said who found that Xiaohong?"
Li Xing clapped his hands: "Look at my memory, it was Wen Qiusheng, our clerk at the Lion House. He sent a message to Xiaohong, saying that it was Xiaohong's former sister who asked her to reminisce about old times!"
