Yan Bing listened to the whole story and nodded slowly.
It turns out that the last realm in this world, the realm of transformation, not only depends on martial arts cultivation, but also tests the state of mind...
Knowledge points..., write them down, write them down...
Yan Bing was about to memorize it silently when a question suddenly came to his mind...
Since this last state places so much emphasis on the state of mind... then... that guy in the yard who was rolling his eyes so hard... how did he reach the state of transformation!???
This is unscientific!??
As far as his state of mind is concerned, at most he has graduated from elementary school, but has not yet completed junior high school...
Could it be...??
Haha... It seems that in terms of martial arts talent alone, you are better, Master...
Regardless of your state of mind, you can overcome the bottleneck by relying on your martial arts talent. I guess you are the first person in ancient and modern times...
"I've finished speaking. It's time for you to fulfill your promise, right!?" Li Lingyue was pressing her chin with both hands, leaning on the table, staring at Yan Bing with her big eyes unblinking, and her aunt's smile appeared at the corner of her mouth again...
"I contradicted him on the street, and he dug a hole for me. In the end, he dug a hole for himself, and then he fell in love with me. End of story." After Yan Bing finished this long sentence, he went back to the cooking pot and started again.
He lit the fire and ignored the "petrified" Li Lingyue.
"Yan!! Qi!!! Hua!!! I'll x your uncle!!!" Li Lingyue blushed, banged the table while yelling, and finally ran out of the basement angrily. Along the way, she kept hearing her
The echo of smashing the wall….
"Tsk! Why is this kid still swearing!? Really..." Yan Bing muttered to herself and continued to tinker with her soap.
The soap in the pot has gradually taken shape.
Yan Bing took the fire stick, picked up the handle of the cooking pot, slowly placed the pot on the ground, waited for it to cool, then took out the top layer of soap, and poured the thick layer of fat on the ground into the porcelain bottle.
Yan Bing held up a bottle full of oil and smiled.
Glycerin get!
The next step is nitric acid!!
Yan Bing first moved out the calcining furnace that was built in advance and piled it directly into the backyard. After all, the process of calcining saltpeter and then obtaining nitric acid through oxygen blowing and water separation will produce a large amount of carbon dioxide. If it is produced in a closed underground space
If so, maybe she would be dead before nitric acid was produced...
Due to the overall size of the calcining furnace, her small micro-blast furnace cannot be molded in one piece. It can only be divided into several parts and then connected one by one using the sliding seam method. Therefore, it is difficult to ensure airtightness.
Let's treat a dead horse as a live doctor. If it succeeds, it will be better. If it fails, we will have to spend some effort to find a larger venue and build an integrated calcining furnace.
After setting up the calcining furnace in the backyard, Yan Bing began to put saltpeter into the calcining place, spread coal underneath, filled the hollow layer with water, and placed a porcelain condensation port under the
Can.
After everything is properly prepared, light the coal and start blowing the bellows to increase the oxygen content in the hollow layer.
After half an hour of burning, the condensation port finally reacted, and a drop of light yellow liquid fell into the porcelain bottle.
Light yellow!!??
Yan Bing was immediately overjoyed. He never expected that this simple set of equipment could extract light yellow nitric acid with a concentration of over 68% in one go. He was a little overjoyed.
Yan Bing, delighted with the past, couldn't help but increase the intensity of the bellows.
After calcining for two hours, the small porcelain altar was half full. Yan Bing found a bucket of water, doused the coals, and found a porcelain cover that had been fired in advance. He covered it with yellow clay.
Carefully wipe all the gaps and completely seal them with nitric acid.
After all, it would be no joke if this thing evaporated in the air.
All that's left is to wait for the right time...
Yan Bing raised his head and felt the coolness of late autumn, and smiled proudly. It was not long before the required temperature...
Because to make nitroglycerin, it must be successful in an environment below 10°C. In ancient times when there was no "refrigerator" and a large amount of ice, if someone said that he could produce nitroglycerin all year round, that would be pure nonsense!
!
In order to prevent the nitric acid from evaporating during this period, Yan Bing found another shovel, dug a hole in the corner of the backyard, put the nitric acid in, buried it with soil, marked it, and called in soldiers to notify the yard.
Everyone here is not allowed to approach this location.
She didn't bother to explain the specific reason, so she lied and claimed that she had created the poison and buried it underneath, and anyone who touched it would die.
After doing all this, we will wait for dawn tomorrow and classes will begin~~.
Yan Bing stretched out, dragged his tired body, pushed open the door of his room, lay down on the bed, fell down and fell into a deep sleep...
Early next morning.
Yan Bing, who had long been accustomed to going to bed early and getting up early, put on her colorful skirt, arranged her hair in a bun, and went to the courtyard after mentioning Qingxuan.
The waiter had already been waiting for her with a bamboo stick.
The waiter's real name is Zhao Cheng, and his father spent three cents to get it from a poor scholar from the village.
When Zhao Cheng told Yan Bing the origin of his name, Yan Bing just smiled.
Although she didn't know why the scholar gave him the word "成", but just based on the level of naming, it was not difficult to deduce why the scholar was in such a miserable state...
Ever since Zhao Cheng entered the house, Yan Bing would call him in every time he practiced swordplay. After two or three days, Zhao Cheng developed a habit of waiting for his "master" in the courtyard early.
Although the two of them just held a simple master-disciple ceremony, Yan Bing didn't care about it in the first place.
After practicing for two hours, Yan Bing told Zhao Cheng to take a rest and practice more diligently in the backyard before going out.
He went alone to the Yongding River three miles south of the city.
Of course, the so-called single was just what she thought. The old man and the emperor's secret guards had been secretly following her...
After nearly a month, with the joint efforts of more than 2,000 soldiers and more than 1,000 craftsmen, the simplified version of the "Academy of Chemical Sciences" has been basically completed.
It's exactly like the drawings she originally designed.
The huge courtyard wall stretches for nearly thirty miles, and the inside of the courtyard wall is divided into six areas.
These include:
The casting area consists of hundreds of blast furnaces and hundreds of smelting pools, used for mass production of steel and spare parts.
The chemical industry area is composed of dozens of workshops, and each workshop is independently surrounded by a courtyard wall. This is to avoid mistakes in the manufacturing process, causing greater impact and losses.
The waterwheel area is mainly distributed along the river. Twenty huge waterwheel workshops are built in a row along the river, mainly used for grinding, drilling, hammering, and mixing.
The assembly area is specifically responsible for assembling and dispatching the spare parts and materials produced in the previous areas. It has also built dozens of huge warehouses.
The teaching area is a place dedicated to giving lectures to other craftsmen and distributing drawings.
Of course, Yan Bing does not intend to teach in person. Doing so would not only be stupid, but also inefficient.
She had already instructed the chief craftsman in advance to select a group of top students from these craftsmen, and she would bring them back to her personal laboratory for teaching, and then they would teach other craftsmen in batches. This not only greatly improved efficiency, but also
It can free up more time for Yan Bing to do more important things.
The living area, as the name suggests, is mainly a residential tile-roofed house, where craftsmen sleep and eat. It is equipped with canteens, warehouses, reservoirs and other living buildings.
At this moment, Yan Bing stood on the top of a tree ten feet high, looking down at his "proud work" from a high place, and smiled happily.
Chinese civilization will take this as its starting point and once again stand on top of the world!!
How can this not make people excited and excited!!
