Benjamin hurriedly stepped forward to explain the situation, and said with a weak Hebrew breath: "Try it, the Ninth Prince's status is noble, how could he joke about such a thing?"
Seeing that he said so, his doctor no longer objected.
After the injection, Li Changfeng left.
Benjamin followed behind and said with an apology: "Dear Ninth Prince, I'm so sorry, the Count's man is really a bit rude."
Li Changfeng said indifferently: "It doesn't matter, you are my real friend."
Benjamin was overjoyed and sent Li Changfeng out of the inn respectfully, and then turned back.
When Hebrew lives, everything will be fine.
The Hebrew died and it was a lot of trouble.
Li Changfeng didn't care about this. After returning to the mansion, he made mutton stewed with iron pot on the earthen stove in the backyard of the mansion. It was already dark when he had enough to eat and drink.
A kerosene lamp was lit in the yard, which looked a little dim.
The extraordinary existences like Chunni and Li Changfeng have little impact on their vision, but it is very big for others.
Bingbing couldn't help but complain: "The night is so annoying. You can't see anything clearly, and it's inconvenient to do anything."
Xiaotong nodded in agreement: "Yes, I hate the night the most. It's dark everywhere, so terrible."
Upon hearing this, Li Changfeng thought and smiled and said, "Since that's the case, then the prince will invent something that will make the night as bright as the day."
Bingbing and Xiaotong had never doubted Li Changfeng's words, and both of them looked expectant.
"Your Highness, then you have to hurry up!"
"Yes, your Highness, don't forget this!"
Chun Ni was a little suspicious: "This is impossible. In this world, what else can shine the night like daytime?"
Li Changfeng smiled and said, "It is a bit exaggerating to say that it shines the night as bright as the daytime, but it can indeed illuminate the night."
"Don't you use fire?"
"no."
"I don't believe it!" Chun Ni shook his head.
"What if I do it? Would you please agree to me with a condition?" Li Changfeng tentatively said.
"not good."
Chun Ni was not fooled and left after saying that.
Li Changfeng didn't care. After washing up, he returned to the bedroom and thought about the feasibility of inventing electric lights.
There is no problem with making glass for light bulbs, and you can do as much as you want.
The metal tungsten used to make filament is not a big problem with the current metal purification technology of the Institute of Science and Technology, but the purity will inevitably be a little worse, but it will not affect the use.
Then the only thing that needs to be solved now is the power problem.
In fact, when he was dealing with the flood in Shangzhou last year, he had the idea of building a hydropower station. However, the construction technology and material technology were too backward at that time, so he gave up this idea.
But today is different from the past. Construction technology and material technology have made great breakthroughs. Building hydropower stations is no longer a dream.
Of course, Li Changfeng did not expect to build world-class hydropower stations like the previous life, such as Sanxia, Gezhouba, and Baihetan.
With the current situation, it is very satisfying to be able to build a small hydropower station with a small county town and a small river.
The road needs to be walked step by step.
However, it is now winter, and it is impossible to start construction of hydropower stations. This plan can only be carried out after the beginning of spring next year.
Then the only way is to generate the generator.
Generally, generators use internal combustion engines as power source, so Li Changfeng settled down and decided to use steam engines as power source.
After conceiving a rough idea, Li Changfeng fell asleep.
The next day, Li Changfeng got up early and went to the Research Institute to communicate with Liang Dafu for almost a day.
Li Changfeng explained the law of energy conversion, the law of electromagnetic induction and the law of electromagnetic force in detail, and conducted field tests with copper wire.
After confirming that Liang Dafu understood, Li Changfeng explained in detail the structure of the large motor.
Liang Dafu digested it for a while before he understood it thoroughly. After thinking for a while, he said, "Your Highness, according to the three laws you mentioned, if there is power input, the generator can also run on its own, which will become a new power.
source!"
Li Changfeng was very satisfied with Liang Dafu's divergent thinking and couldn't help but give him a thumbs up: "You are right, so I plan to build a hydropower station next year to use water as power to generate electricity, and then try to make a motor. This is what I said.
the power source.”
"Just like the folk waterwheel?"
"It's almost the same, but hydropower stations are more efficient in utilizing water energy."
Liang Dafu became very interested: "How to do this specifically?"
Li Changfeng looked at the sky and said helplessly: "You can't chew too much, so you'd better get the generator out first."
After saying that, he got up and left, and Liang Dafu fell into deep thought.
When I returned to the mansion, I saw Benjamin Marquis at the door again.
"Your Highness, the Hebrew Earl's condition has been relieved! Your medicine is effective. Please send someone to give him another shot!"
Li Changfeng was not surprised at all.
Penicillin is the first antibiotic in the world, and it is also the first time that Hebrews has used antibiotics, and there is no such thing as drug resistance.
Therefore, penicillin has excellent effect.
After that, with the large amount of penicillin used, the effect will gradually decrease, but this is a long process.
"It works, but one injection may not be enough. It takes a lot of injections until it is cured. I will arrange a doctor here." Li Changfeng said with a smile.
"Your Highness, what other diseases can this penicillin cure besides treating pneumonia?"
Hearing this, Li Changfeng suddenly felt energetic, and he guessed Benjamin's thoughts.
"There are many things that can be cured, such as upper respiratory tract infections such as tonsillitis and sinusitis, lower respiratory tract infections such as pneumonia and bronchitis."
"In addition, it can also treat diseases of urinary tract infections, and even treat syphilis, gonorrhea and other venereal diseases..."
Next, Li Changfeng introduced the effects of penicillin in detail. The more Benjamin listened, his expression became more and more excited, and his eyes became brighter. Although it was the first time he heard strange terms such as urinary tract infection, syphilis, gonorrhea, etc., he probably knew it.
mean.
"Dear Ninth Prince, can you help me get penicillin? Of course, I will pay you the labor remuneration!"
Benjamin looked expectant.
Through Li Changfeng's description of penicillin, he has realized its huge market value, which is simply a mountain of gold!
Those who are sick and have no cure are willing to pay any price for this.
Li Changfeng laughed silently: "No need to be so troublesome, penicillin was produced by this prince."
Benjamin was overjoyed: "Okay, that's great. Your Highness, what is the price of penicillin?"
"Ten taels of silver per piece."
"Then I want fifty thousand, okay?"
"Of course, this prince is provided with ten syringes."
Li Changfeng was in a good mood, and after returning home, he negotiated a big business.
