Lin Yuan smiled disdainfully: "Even if I tell you, it's useless, because these things are not something you can make at all, to take the simplest example, ethylene oxide, can you make it?" ”

The curator is a student of history, and has spent most of his life dealing with books, so he doesn't know anything about chemistry, so he doesn't understand the word "ethylene oxide" at all. People are like this, they are always resistant and contemptuous of things they don't understand, so the curator said, "What are you talking about? I can't understand a word! ”

Lin Yuan smiled: "There are so many things you don't understand, can you deny its correctness just because you don't understand?" ”

The curator said impatiently: "Don't talk nonsense here, hurry up and get out of the way for me!" ”

Lin Yuan then pointed to the storage cabinet next to him and said, "It's okay if you don't believe it, but the precious cultural relics in your museum have already been damaged, if you are willing to watch them continue to be damaged, please do it." ”

After Lin Yuan finished speaking, he turned around and left, and the curator said in the back: "Do you have a way to prevent them from being damaged?" ”

Lin Yuan smiled: "Of course I have a way!" But you guys are too backward here, and I can't do anything about it, if they are shipped to our China, I will definitely be able to save them! ”

Lin Yuan continued: "These collections are treasures of the entire world, so you can bear to let them stay with you and become moldy and spoiled?" Our descendants will spit on our graves! ”

The curator thought for a moment and said, "I can't trust you for nothing, so let's do something to prove that you really have the ability to protect these cultural relics, and if you can do it, I will believe you." ”

Lin Yuan said coldly: "I am also a person who can't see precious cultural relics destroyed, and the purpose of my coming here is very simple, that is, to send these precious cultural relics to our China, to protect them well in our country, if I can prove that I have the ability to protect them, you will send these precious paper and silk cultural relics to our China!" ”

Lin Yuan thought very clearly in his heart, most of the Chinese cultural relics in the Paris City Library were paper products and silk fabrics, and in this way, not only could the precious cultural relics of China be returned, but also the precious cultural relics looted by the French from ancient Egypt, ancient Babylon and other countries.

The curator said, "We have just received a batch of precious papers from China, which are said to be the edicts of the king of Nanzhao, and if you can protect them with the techniques you mentioned, I will agree to your request." ”

Lin Yuan knew that the Nanzhao of the Tang Dynasty was a minority regime established in Yunnan, which was later destroyed by Duan Siping and established the Dali State.

Lin Yuan asked, "Where did you get these things?" ”

The curator replied: "We bought it from the locals, and it is said that the locals dug up the tomb of a minister of Nanzhao, and got a lot of good things out of the tomb, among which gold, silverware and jade were bought at a high price, and there were no one to ask for silk fabrics and books, so we used less than a pound of eggs to recover a large number of them." ”

Lin Yuan sighed silently in his heart, and then said, "You don't know anything about techniques at all, can you evaluate my ability to preserve cultural relics?" ”

"I'll be looking for my peers, many of whom are experts in heritage conservation," said the curator. ”

Lin Yuan said: "Okay, you hurry up and find someone, and I will show you my skills tomorrow." ”

The curator agreed, and Elena sent Lin Yuan to the door, and asked carefully, "Do you have that ability?" I know that my father has some friends, all of whom are very experienced experts, and many of them have been studying the protection of cultural relics all their lives. ”

Lin Yuan smiled: "Don't worry, they are definitely not my opponents." Lin Yuan said goodbye to Elena, went to the Curie couple, from their place of work to ask for the chemicals they needed tomorrow, and when they returned to the inn, they asked people to send a letter to President Fore, urging him to persuade the parliament as soon as possible, in the letter Lin Yuan was both threatening and intimidating, the wording was extremely tough, and the messenger came back to report that President Fore was already working hard, and many people in the parliament had agreed.

The next day, Lin Yuan took his assistant to the Paris City Library, and as soon as he arrived at the door, he saw Yelena standing aside with a sad face, Lin Yuan quietly stepped forward and asked, "Do you need me to help you?" ”

Elena remembered what happened yesterday, couldn't help but blush, and hurriedly said: "I was almost discovered by my mother yesterday, and I won't dare to do that in the future, by the way, are you ready?" ”

Lin Yuan smiled: "Of course! Lin Yuan couldn't help but look back at the assistant with a lot of chemicals, and thought, "If only I could use a computer to show a slideshow." ”

Elena took Lin Yuan into a lecture hall, there is an optical projector at the front of the lecture hall, this projector can enlarge the content on the paper using optical components, and then image on the screen in front, the projectors used by Lin Yuan are all used by electronic technology, directly connected to computers and other equipment, this kind of optical projector Lin Yuan has seen when he was in elementary school.

Lin Yuan looked at this ancient projector and thought, "I still have some pictures that I want to send to them during my speech, and this time it's just right that I can use this projector." Lin Yuan looked at the audience, only to see that everyone in the audience looked at him with bad intentions, as if they were all waiting to see their jokes, Lin Yuan thought to himself: "Okay, since that's the case, I'll tell you something that you don't understand." ”

Lin Yuan took out an electromagnetic spectrum map from his bag, this map is drawn on the various bands of electromagnetic waves, Lin Yuan wants to illustrate the harm of ultraviolet rays to paper cultural relics through this picture, Lin Yuan thought: "The electromagnetic spectrum map was only drawn in the twentieth century, you must not have seen it, just wait to be shocked by me." ”

Lin Yuan turned on the projector and put the electromagnetic spectrum on it, but what he didn't expect to hear was not an exclamation, but a laugh, Lin Yuan wondered in his heart, thinking: "What is so funny about you?" When I turned my head to look at it, I realized that the picture was actually upside down on the screen! It turned out that the optical projector was an upside-down image when projecting, so everyone laughed.

Lin Yuan hurriedly turned the picture around, stretched out his hand to signal everyone to be quiet, and then said, "Today I will tell you about the damage of light to paper cultural relics. ”

Everyone didn't think that light could also cause harm to cultural relics, so they all quieted down and listened, Lin Yuan continued: "Everyone knows that paper cultural relics are very easy to be destroyed, because the main component of paper cultural relics is cellulose, this kind of thing is very fragile, and it is easy to oxidize and be destroyed under ultraviolet irradiation, so when storing, the light source in the storage room should be strictly controlled, and the light source should be a cold light source that does not emit ultraviolet rays." ”

Lin Yuan pointed to the electromagnetic spectrum on the screen with his hand and said, "Everyone, please look, this is the location of ultraviolet rays." Saying that, Lin Yuan took out another pen-like thing and pressed it on the screen, and everyone couldn't help but let out an exclamation.
