It was obviously Xu Youtang's first kiss. Her movements were green and clumsy, and Zhang Yanling's lips were sore due to her teeth. But she tried her best to accommodate her. After Zhang Yanling's sexual intercourse, she quickly became proficient.
After a tender and sweet kiss, Xu Youtang lay in Zhang Yanling's arms with her face like red clouds and sighed with satisfaction.
"Master Hou...!"
"how?"
"It's nothing, I just want to call you. However, it's a bit awkward to call me Hou Ye. Otherwise, from now on, I'll call you brother and you can call me Tang'er." Xu Youtang said softly.
"Okay, Tang'er!" Zhang Yanling said with a smile. The girl's mind is always so boring and never tired of it.
"Brother...Brother." Xu Youtang said softly.
Zhang Yanling agreed with a smile, and Xu Youtang hugged Zhang Yanling's neck again and kissed her. The two were mixed together again, and they separated after a long time out of breath.
"Should I give you a token of love? But I didn't expect that we would end up like this, so I didn't bring anything valuable with me. Can I give it to you after I get home?" Zhang Yanling said with a smile.
Xu Youtangnu said in Zhang Yanling's arms: "Hey, I don't have anything valuable to give you. However, my gift has already been given to you."
Zhang Yanling smiled and said: "When did you send it? How could I not know?"
Xu Youtang twisted his body and said angrily: "That firearm, when I made it with my own hands, I was thinking that this firearm was given to the person I love as a token of love, but you didn't know it."
Zhang Yanling burst out laughing. It turned out that Xu Youtang had had such thoughts for a long time. The short-handled fire gun was a love token she gave to herself. It was funny and touching at the same time.
There was really nothing to do with me at the moment, but I couldn't say nothing. I looked around and saw the beautiful lotus blooming in the reservoir, so I smiled and said: "Mei Tang, I'll pick one for you."
How about giving you lotus flowers?"
Xu Youtang nodded in agreement, and Zhang Yanling stood up and quickly took off his coat, unfastened his belt, firearms and other items. With a "pop" sound, he jumped into the reservoir.
When it got dark, Zhang Yanling and Xu Youtang returned to the capital. Xu Youtang could not stay home all night. Although the cool weather at night was the most suitable time for construction work, if Xu Youtang stayed away all night because of this, Xu Gao would definitely find that Xu Youtang might be able to
We can no longer go out during the day without telling him.
In order to solve this problem, Zhang Yanling came up with an idea and asked Xu Youtang to explain some basic structures and principles of the lotus stove, as well as the key points in construction to two craftsmen, Sun Wanhou and Li Dagen, in the afternoon. Those two people were also experienced builders.
Craftsmen are also very proficient in smelting furnaces. Although it is not their common furnace, the basic principles are the same, so they can understand it quickly.
In this case, even if Xu Youtang is not present, Sun Wanhou and Li Dagen can still be competent in the initial construction work. At least there will be no problems in the furnace foundation stage. Zhang Yanling will bring Xu Youtang here later, so that they can supervise the construction in a timely manner.
It can also ensure progress.
…
At the end of August, after more than half a month of construction, the two-foot-tall lotus-shaped smelting furnace was finally completed. Zhang Yanling naturally came to witness the last moment in person.
From a distance, the entire smelting furnace looks like a tall and graceful vase placed on a pedestal. When viewed from a high position on the beacon tower, it looks like a budding lotus.
The internal structure of the entire smelting furnace contains some special secrets. The eight-petal lotus-shaped small furnace is not for appearance, but to divide the area inside the furnace. When smelting fine steel, the temperature difference between the large and small furnaces is used to achieve the effect of internal and external stratification.
The internal furnace temperature can be fine-tuned in rounds. According to Xu Gao's notes, this will allow the injected clay to better integrate into the molten steel and undergo several reactions.
Naturally, Zhang Yanling didn't understand the principle here at all. Xu Youtang also knew it but didn't know why. This was what was written in Xu Gao's albums and notes, and she didn't understand the reason. In fact, Zhang Yanling believed that Xu Gao
This must have been discovered through a lot of experiments,
It is speculated that some unknown reactions carried out by the trace elements in the white clay into the steel require this layered fusion and intersection process. The reaction is carried out using a short low temperature difference, and the final result is obtained. The unknown factors involved are
The process is a mystery that is difficult to describe.
As for the differences in other aspects of the smelting furnace, there are more. There are three fire doors at the bottom. If necessary, the fire can be added and removed from three sides, which is conducive to heating and cooling in a short time. There are more valves, and there are ten fire doors around the bottom of the furnace.
Several valves of different sizes are used to adjust the coordination of the fire. Different valves can control the size of the flame, and the size of the fire door can accurately control the furnace temperature. This is the basic secret of smelting refined iron.
All in all, this lotus stove was finally made by Xu Youtang. There were some problems in the process. Things on the drawings will always be different when implemented in the real thing, but Xu Youtang still solved these problems.
In the evening of that day, the smelting furnace began the ignition test. The fire reached an incandescent color in a very short time. The internal structure of the furnace was stable, and the refractory masonry did not peel or crack. In the smoke coming out of the tall chimney above
It also has a stable blue flame. All this shows that the stove is truly successful.
Zhang Yanling did not delay. He immediately divided his troops into two groups and began to make final preparations for smelting refined steel. The first was the white clay that Xu Gao mentioned. That was the key raw material. According to Xu Gao, it was a kind of clay produced in Jiangxi.
A man called the soil in Longhu Mountain, Xu Youtang came from
I brought some samples at home. It was a kind of fine soil between gray and white. It was obviously ground and finely sifted soil, as fine as flour. The specific location was not detailed. Zhang Yanling decided to go to Jiangxi in person.
I went to Longhu Mountain to find this kind of white soil.
In addition, raw materials need to be purchased in large quantities. They are green iron and yellow iron. Green iron is the best because it is pig iron produced in the mine. It has fewer impurities but is more expensive. Yellow iron is cheaper but has more impurities. Both are needed.
Because not all the parts on the gun need precision
Steel and some other parts do not need to be made of extremely high quality and can be used together. Fortunately, the price of iron in the Ming Dynasty was not too high. A pound of blue iron was about two hundred dollars, and a pound of yellow iron only cost about a hundred dollars. But
Because it requires large quantities of purchases, it also costs a lot of money.
This time, Zhang Yanling took Chen Shiyi and dozens of Jin Yiwei to Jiangxi. Under the guise of official business, he was actually doing it for the public good. It took him several days to arrive in Jiangxi. He found out the location of Longhu Mountain and went into the mountain to find it.
After two days, I finally found this kind of white soil in a secluded valley.
After on-site ink grinding and sifting, it was confirmed that it was correct. They dug thousands of kilograms of soil, packed it in sacks, and brought it back in three large trucks. According to Xu Gao's notes, this kind of white soil is actually not practical in quantity.
Large, thousands of kilograms of white clay may only be usable after removing impurities and sieving it, but it is still enough to smelt hundreds of furnaces. It is completely sufficient.
After a lot of trouble, it was already the Mid-Autumn Festival. After the Mid-Autumn Festival, Zhang Yanling couldn't wait to start the first smelting.
