Volume 1: Birth! Seven time travelers Chapter 054: Climbing the Technology Tree Together (Part 3)
Finally, there is the gunpowder group.
"Your Highness, we have refined the gunpowder again according to your method. After soaking it in water, we used a fine sieve to form particles, and then dried the granular gunpowder. Its power is indeed much greater than original one. In addition, according to what your Highness said, adding various metal particles to the gunpowder can indeed make the fireworks explode in different colors. However, according to Mr. Xu's order, we dare only conduct experiments indoors during the day. If we can take it to the field at night to conduct experiments, I think the effect will be very good."
"Masters, your next work is divided into two parts. The first is fixed-charge gunpowder. The army of my Ming Dynasty now has firearms, if not 70%, at least 50%. But it is too troublesome to load gunpowder with a matchlock gun, and the amount of gunpowder to load depends entirely on the gunner's personal experience. What I mean is to launch fixed-charge gunpowder, wrap it in paper shells, and when it is needed, the gunner can just bite open the paper shells."
"Your Highness, this is not difficult. It is very easy for us to evenly distribute the gunpowder after granulating it. But Your Highness, the workshop of the Ministry of Industry, ah, this..."
"Haha, what you two masters are trying to say is that if the quality of the gun barrel is not improved after the power of gunpowder is increased, it will easily explode?"
"Your Highness is wise. We all used to work in the Ministry of Industry. The master who made the gun barrel, uh, let me say something disrespectful, given the environment in the Ministry of Industry, the master who made the gun barrel really couldn't do a better job."
"Yes, I understand. Thank you for reminding me. I plan to have our own blacksmith make a few reliable gun barrels in the manor to test the new granular gunpowder."
"Oh? That's no problem. We trust the craftsmanship of Master Huo and his men."
"Very good, then masters, your next job is to make fireworks."
"Fireworks? Your Highness, fireworks are not difficult. It's just that Your Highness asked so carefully, but is there anything special you need?"
"Hahahaha, smart! Grandpa Emperor's birthday is on the fourth day of September every year. You all understand what to do, right?"
"We understand. But please tell your Highness that when the time comes, please ask the guards in the manor to escort me to a deserted wilderness to conduct the experiment."
"Of course. I'll let Lao Wei make the arrangements later."
After the gunpowder group's master left, Xu Guangqi also stood up and said, "Your Highness, I am still a scholar after all, and sometimes I still need to work in the Imperial Academy. Sometimes I am really unable to handle things in the manor. And I see that your ambition, at least in the matter of gunpowder, is definitely not satisfied by just lighting fireworks to please the emperor. So, I want to recommend someone to your Highness ."
"Well, I also thought of the person Mr. Xu mentioned. How about this, Mr. Xu, contact him first, and I will visit him in person tomorrow night."
"Your Highness is respectful to the wise and humble, which is a blessing for the Ming Dynasty."
"Haha, it's only right to retain talented people for the country. Mr. Xu, it seems that the glass production will soon produce results. Three months ago, I asked Mr. Leach to write to Macau and find a few craftsmen who can grind lenses for me. It's been so long, and I don't know how things are going. Please pay more attention to this matter, Mr. Xu."
"Yes, I understand. In this case, I will take my leave."
Now, Honghe Village has gradually developed various rules. The biggest rule is: everyone should do their own thing, and no one should interfere with anything outside of their job without Zhu Youdong's permission.
Even the technology director Xu Guangqi had to step down at this time. Because the next person who came in was also reporting on technology, but as a science and engineering guy, it .
"Student Wu Youxing, greetings to the teacher!"
"Oh, Doctor Wu... Doctor Wu, I've told you so many times not to call me teacher. I'm not even six years old, how can I be your teacher?"
"I dare not. The one who is more accomplished comes first. Age and so on are not a big deal. The teacher is a scholar of heaven and earth. I am willing to follow the teacher for life and explore the ultimate truth of medicine!"
Although I was somewhat of a small figure in my profession before I traveled through time, even among those big figures, who dares to say that they have touched upon the highest principles of medicine? However, if it comes to teaching you Chinese medicine, I am absolutely incapable of doing so. But if it comes to teaching you some modern medicine, I can definitely be your teacher. Forget it, call me whatever you want, anyway, I am not even six years old, so you can't call me old.
"Uh, there is sex. Have you finished studying anatomy?"
"Yes, I have seen them all. I have dissected countless rabbits, pigs, cows, sheep, etc. As for this human corpse, although the teacher asked Master Li to send some to me, the person is dead, and the blood circulation will naturally stop. So, it is a bit regrettable..."
What? Do you want to dissect a living person? Even I can't accept this.
In fact, there were many famous doctors in the Ming Dynasty, which lasted for two or three hundred years. Specifically speaking, if it weren't for the foresight of the time traveler, Wu Youxing would have to wait for decades to become famous. The truly famous doctor at that time was Zhang Jiebin. His greatest contribution was to systematically sort out the contradictory or overly complicated things in various medical books over the past two thousand years since the Yellow Emperor's Classic of Internal Medicine. This made the entire medical system clearer and easier to learn... However, this master of traditional Chinese medicine specializes in treating the powerful and the rich. His pioneering and exploratory spirit is far inferior to that of Wu Youxing. So when considering who to let make the smallpox vaccine, Zhu Youdong chose Wu Youxing.
However, Wu Youxing's passion for technology was too high. Not only did he refuse the Wanli Emperor's order to recruit him as an imperial physician, but he also moved directly into Honghe Manor, saying that he wanted to continue studying medicine with Zhu Youdong.
"Yes, I have only one request. If the safety of the drug is confirmed in livestock testing, living people can be used for drug testing, but living people are not allowed to be used for dissection experiments! Can you do it?"
"Yes, teacher, don't worry, I still have some conscience."
"Well, how are you doing with the extraction of sulfanilamide?"
"We have already made a batch of finished products. The students first tested it on mice and piglets according to the teacher's instructions. After seeing the effect, they also found some patients with colds to take it. The effect is excellent!"
The so-called sulfonamide drugs. They have a killing effect on streptococci and also have an inhibitory effect on many other bacteria. They were the most effective antibacterial drugs before the advent of penicillin. And their source comes from a red dye.
As a doctor, Zhu Youdong is very familiar with this history. When he was studying medicine, he worked with his classmates from the School of Pharmacy of the same university to complete the production of sulfa drugs.
Benzoic acid is extracted from urine, and then benzene is extracted. Benzene then reacts with acetic acid to form acetanilide. Once acetanilide is obtained, sulfonamide is not far away.
(The whole process is actually very troublesome and contains a lot of harmful substances, so I won’t write about it in detail here)
"Well, please be aware that raising animals is also very dangerous. I will send you ten smart children to be your students and assistants in a while. You can raise them in your own laboratory."
"Yes, speaking of which, I would like to thank you for your kindness. All the new glass produced in the village has been installed in my laboratory. The lighting is much better. It would be even better if the impurities can be cleaned up as soon as possible so that the glass does not have its own color."
"The matter is almost resolved. As for you, how is your intravenous infusion going, another task I assigned to you?"
"Master Huo from the Iron Group has already made a batch of needles for infusion for the students. The masters from the Leather Group have also cleaned the sheep intestines and other things very well. It's just that there are too many impurities in the glass bottles, and the airtightness of the corks ..."
"There are still so many problems? Come on, tell us about them one by one in detail, and we will gradually improve them together."
