"Well, to put it simply, electrons are moving all the time, but the movement of electrons in most substances is irregular and chaotic, so they are not magnetic. However, iron, nickel, and ferrite are metals www.biquge.info and the electrons inside them can be spontaneously arranged in a small area to form a spontaneous magnetization zone, so when the magnet is close to them, it can be absorbed by the magnetic force, and this ferrite is found in the dissolved substance of this gold, so it reacts to magnets. Yunli tried to describe it to them in simple language.

"That doesn't prove that the contents of this copper candlestick are gold, and if the people who make it are bored and pour molten iron into it, it will still attract magnets, right?" Wang Yuyao obviously understood, and asked this tricky question.

Yun Li had thought about this problem a long time ago, the reason why he didn't dare to be 100% sure that the copper candlestick was shining gold, was afraid of such a dramatic scene, but he also had a corresponding test method, only to see him take out a mobile phone charger, unplug the data cable interface, expose the positive and negative wires inside, he glued the copper wire of the negative pole of the wire to the copper candlestick with tape, and then connected the charger to the power supply, holding the copper wire of the positive pole in his hand, and swept back and forth on the other side of the copper candlestick.

Although everyone didn't quite understand the principle, but seeing Yunli so serious, they didn't bother sound, and watched him operate seriously, and it didn't take long for the small horn that had been placed on the side of the copper candlestick to fall down without warning, and it turned around on the table a few times before it fell to the tile floor, making a crisp sound of "pop".

"Magnetism gone?" Wang Yuyu was surprised, and Ren Fei and Wang Chengyuan also showed incredible performances, and the three of them were expecting Yun Li to explain the reason to them.

Yunli took back the wire, pulled out the charger, and also picked up the small horn that fell to the ground, put the small horn on the charger, and the two were tightly "glued" together.

"I just used the current of the charger to disrupt the electronic movement in the copper candlestick, with magnetic matter, so it temporarily lost its magnetism, the magnet in the small horn can not sense the magnetic force will fall, if the material in the copper candlestick is iron, this amount of current is not enough to affect its magnetism, we all know that the charged iron, the magnetism will be stronger than usual, this experiment proves that the substance injected into the copper candlestick is not iron, it is sure to be shimmering gold."

In fact, Yunli didn't need to use a charger at all, the electromagnetic force in his body was enough to provide the required amount of electricity, but he couldn't show this ability in front of others, so he spent so much effort to show them.

After confirming the existence of Shuo Jin, Ren Fei and the three of them all smiled, and Ren Fei couldn't help but be overjoyed: "Oh, this trip is not in vain, if Lao Pan knows that such a treasure has fallen into my hands, I don't know what he will look like." ”

"Pan's family business is so big, and there are many more precious collections than this, but it is such a thing as a blind eye, which may really hurt his old man's face, after all, he has a lot of fame in the collection world, and he is still one of the shareholders of several auction houses." Wang Chengyuan said while fiddling with the copper candlestick.

Ren Fei laughed and said: "That's right, that old guy's face is very thin, I went to his house last night to catch up, and found that that guy has not been idle all these years, and has collected many superb treasures, I don't know if he has hidden it and tucked it without showing people, just those collections are enough for him to open several exhibitions." ”

"By the way, Xiaoli, how did you discover the secret in this bronze candlestick, there were so many big experts present at that time, and even Pan Lao and the teacher couldn't notice it, shouldn't you still have any unique skills hidden?" Wang Chengyuan asked Yunli.

Yun Li had long expected them to ask this question, and the corresponding excuse was also made: "If you want to pass the shimmering gold in the copper candlestick to the wick of the candle, and you can't let people discover the existence of the shimmering gold, then the chassis where the candlestick is placed must also be specially treated." You see that these two leaf-like foils are more oxidative and rusty than in other places, especially on the side of the short candle, which is caused by the slow evaporation of the shimmering gold, but it looks very similar to ordinary rust, and it is easy to confuse people and thus hide this secret. ”

Yun Li pointed to the copper candlestick while explaining to everyone, everyone nodded again and again, this explanation is very reasonable, there is nothing to argue, if it is not someone who knows the inside story, he will not pay attention to this small detail at all, and Yun Li in order to dispel their doubts, he continued to say frankly: "Actually, I know so much about Shuojin, because I also got an oil lampstand containing Shuojin many years ago, but its value is too far from Ren Lao's." ”

"No wonder at the auction last night, you kid was right, and I also sent the gods to listen to you, otherwise this treasure would really have to be given to others." Ren Fei sighed with a smile.

"Old man, you are cheap and good, if it weren't for Yunli this time, you would really miss this baby, how do you think you can thank him?" Wang Yuyao said with a smile.

Ren Fei nodded, turned his head to Yunli and said: "That's true, but I won't give the silk painting to death, everything else is easy to say, if you need help in the future, don't be embarrassed to ask me." ”

"Ren Lao can get the ever-bright candle and the copper candlestick, this should be regarded as fate, if I am really in trouble, I will definitely hug your thighs, I hope you don't kick me away when the time comes." Yunli said modestly.

"Haha, then I hope you come to hug it, you probably won't want these two things, but as an elder, I still boast that there are still some places that can help you." Ren Fei smiled heartily.

"What about me, how can I say that I am also an intermediary introducer, old man, you have to express it, right?" Wang Yuyao said coquettishly.

"If you don't mention it, I've really forgotten about this layer, let me think about it... Girl, haven't you always wanted to do a visit to an ancient building, and when I go back, let people complete the interview permit procedures, and you can visit wherever you want in the southwest, and ensure that it is unimpeded, so you can always do it. Ren Fei had an idea.

Hearing Ren Fei's proposal, Wang Yuyao nodded violently and said, "This is good, it's settled, I'll prepare for this when I go back, old man, don't you fly my kite." ”

"Little girl, the teacher hasn't fulfilled anything, you should prepare for your work, and you will be busy next." Wang Chengyuan touched his daughter's hair dotingly and instructed.

"If you two don't have the bottom of what I just said, don't force me to sign the note, I've lived for so long, and I've never signed this thing. Ren Fei was in a good mood and joked with them.

"That's not necessary, Old Man Ren's words are still very effective, so how do we turn the shimmering gold back into a liquid state now, I'm still waiting to see what kind of beautiful scenery this gold-burning candle will look like after it is lit." Wang Yuyao brought the topic back to the copper candlestick.

"I'm afraid this is not easy to do, the copper candlestick is sealed and cast, if you want to hit the idea of shining gold inside, you will inevitably have to open a small opening for it, not to mention that this solidified shining gold is not so easy to liquefy again." Wang Chengyuan analyzed, and then set his eyes on Yunli.

Yun Li said: "That's true, and this shimmering gold needs to be dissolved by a special secret method in order to make the everbright candle play its due effect, I don't have much research on this, I have to find someone to think about it, and I guess I won't have the opportunity to see it in a short time." ”

"Yes, it is precisely because of this special secret method that these ever-bright candles and copper candlesticks are so precious, and they are also of great research value, and my old friends have good things to do." Ren Fei also agreed, and he already had a preliminary plan.

"Well, since you've all said so, let's have a chance to watch it later, after a busy morning, you must be hungry, let's go have breakfast first." The wish was disappointed, but Wang Yuyao did not have much sense of loss, and beckoned everyone to go to breakfast.

For Yunli, the task of his trip is over, he has seen the silk paintings, he has also obtained the information he wants, and he has also increased his knowledge at the auction, and it is very important that he can get to know Ren Fei and Wang Chengyuan, this relationship is more precious than many things.

Just now Yun Li said that he wanted to hold Ren Fei's thighs was just a joke, with his own character, he would never deliberately befriend the powerful to get benefits from it, and with his own strength, he didn't need to be so bent to meet him. However, Ren Fei and Wang Chengyuan's knowledge and connections are a huge treasure trove, he can learn from them, without violating his own principles, with the guidance of the two of them, the development of Banlu Manor will be smoother, and there will be many unnecessary detours.

Wang Chengyuan's side, in addition to accompanying Ren Fei to the auction this time, they also have some inspection projects to be carried out, and it is estimated that they will have to stay for a day or two before they can go back, Wang Yuyao naturally followed his father, and Ren Fei rarely came once, and he was not in a hurry to go back, he planned to take a good stroll in this Yin City, and invited Yun Li to accompany him, so Yun Li continued to stay.

In addition to the collection of antiques, Ren Fei also has another big hobby, that is, food, he never settles in terms of eating and drinking, he not only likes to eat, but also often cooks a few dishes to entertain relatives and friends, according to his own words, he is all good at eating, drinking and playing, all of them.
