He was betrayed at the beginning, from a cake seller to a wealthy person

Lu Sheng's attempt was once again dodged by Lu Yan, who fled in panic. Lu Sheng had never succeeded before, so he was used to it, and this failure did not cause any fluctuations in his emotions.

The next day, the two men brought the prince to the laboratory to introduce him to activated carbon and alcohol.

The prince was very excited when he heard that Lu Yan had researched something that could benefit the people. He trusted Lu Yan's ideas very much, and in his heart, she even surpassed Lu Sheng to some extent. Lu Sheng was a more orthodox smart person, while Lu Yan was a genius.

The measures for preventing and treating the epidemic, as well as masks and isolation gowns that Lu Yan proposed last time, were communicated to the Taiyuan Hospital when he returned home. After research by several doctors from the Taiyuan Hospital, they were incorporated into the "On Plague" they were compiling at the time and signed. Lu Yan's name. Now almost every doctor in Dali has a copy of "On Plague".

Lu Yan first took the prince to see the activated carbon. When Xiao Tu had nothing to do, he went to prepare activated carbon and alcohol. A lot of finished products had been prepared and placed there, and Lu Yan could use them directly.

Lu Yan brought a jar of dark activated carbon and explained to the prince: "The first thing I want to show you is activated carbon, which is used to filter things. I will do an experiment for you and you will know what it has. used."

Lu Yan took two cups, put a handful of soil in one cup, poured water into it and stirred it, making a cup of muddy water. She poured clean water into another cup, then found some paint, dipped it in red paint and stirred it in the water, turning the clean water into red water.

Lu Yan explained as she stirred: "You see, these two cups of water are no longer clear water. The function of activated carbon is to turn them back into clear water."

The prince actually didn't believe it. The muddy water was okay, but he didn't believe that the cup stained with red ink could turn back into clear water.

Lu Yan filtered two glasses of water with activated carbon. When the last drop of water filtered out, the appearance of both glasses of water changed. Whether it is muddy water or red ink, it has returned to a state very close to clear water, with only a few traces remaining.

The prince's eyes widened immediately: "This, this, this! It really changed back!"

Lu Yan explained: "It has many uses. It can not only filter out unclean water, but also many other things. Isn't there a lot of miasma in the southwest? Let the imperial doctors study it and make a mask. Maybe it can prevent poison and miasma."

The prince was already very surprised and repeated to Lu Yan: "You said it can prevent poisons?"

Lu Yan nodded: "Theoretically yes, you can take it back and let the imperial doctors do experiments. Light the incense in a closed room and burn it for a while. Wear it and an ordinary mask to see what the difference is."

The prince agreed immediately: "That's no problem, this is what they should do."

Lu Yan continued: "The second thing I want to introduce to you is more useful than activated charcoal and can save more lives, but I can't give you a demonstration so that you can see the effect. You can only take it back and let the imperial doctors Find a way to try it, or distribute it to medical clinics in the capital for free."

The prince was confused: "Why can't you show me a lesson?"

Lu Yan came out with a jar of alcohol: "This thing is called alcohol. Many times when people are injured, the wound won't heal for a long time even after being bandaged. Repeated suppuration is a relatively good result, and some people will also have fever. , if it’s serious, you might even die, right?”

The prince often dealt with the army and knew this situation very well. After hearing what Lu Yan said, he immediately said seriously: "Yes, that's the case."

Lu Yan nodded and continued: "Applying medical alcohol on the wound can solve this problem to a large extent. If this problem occurs, you can understand that there are dirty things in the environment that we cannot see with the naked eye entering the wound. Alcohol is just right It can kill them. The only problem is that it hurts when you use it, but compared with its effect, the pain will be gone after a while. "

The prince was excited when he heard this: "Really? Are you telling the truth? Can this really reduce fever deaths among the wounded?"

Lu Yan nodded again: "Of course. But I don't have many wounded here, and I can't cut myself to show you. You can only take it back and let the doctors in the capital do experiments."

The prince was so excited. He didn't expect Lu Yan to offer him such two treasures at once. Although he doesn't really believe in the effect of alcohol, he has seen the effect of activated charcoal with his own eyes. Even if it is only activated charcoal, it has great potential.

Afterwards, Lu Yan took the prince to see the preparation process of activated carbon and alcohol, and explained the entire process and the required equipment to him. The prince came to visit the laboratory on his own for safety reasons, and did not bring anyone with him, so he took notes on his own, and took two pieces of paper to carefully write down each step.

Finally, Lu Yan gave the prince a jar of activated carbon and a jar of alcohol and asked him to take them back. The prince was so excited that he couldn't do anything to Lu Yan, so he simply patted Lu Sheng's shoulder and said, "Don't worry, I will report this to you when I get back. This is a great achievement, and the emperor will definitely reward you."

Lu Yan chuckled: "Can I make a request?"

The prince was a little surprised and asked Lu Yan curiously: "Is there anything you want?"

Lu Yan's calculations were running fast in her mind: "No matter how many rewards Lu Sheng and I don't need, they will all be filled into Liaoyang County. Why don't we apply for a special grant for us and send a scientific research fund to Liaoyang every year? I will use this Keep doing research with money.”

The prince thought about it again and thought that Lu Yan's idea was a good one. The reward could be directly allocated to Liaoyang County to prevent them from embezzling their own small treasury. It would also show that they were wholeheartedly serving the people and were truly good ministers who devoted their lives to the country.

The prince agreed with a wave of his hand: "No problem, just wait for good news."

They will set off again tomorrow. Lu Yan went back to collect the sausages and bacon she had dried and sent them to Prince Yi and his wife, asking them to take them to Princess Anhe and also to convey a message.

Lu Yan said: "Tell her that I have guests to accompany me, and I will go find her before the Chinese New Year."

Prince Yi and his wife were one step closer to seeing their daughter. They were a little nervous and asked Princess Anhe if she was sure she was living well. Was General Yuan treating her well?

Only after getting all the affirmative answers did I finally breathe a sigh of relief and relax a little.
