Ding Fan finally determined the role of these teeth.

On Zou Linong's bookshelf, there are a lot of books, which clearly mark the principle of this thing, as well as the internal structure, and even what kind of mechanism is inside, and so on.

The only thing that is a bit of a fly in the ointment is that there is no mention of how to open this thing correctly.

It's just that there are a lot of annotations on it, and it's clearly marked that things can't be forcibly opened, which may cause internal protection organs, and things may be destroyed at any time.

For this, Ding Fan has been worried about this for a long time, and he thought it was for this that he came to the old professor.

It's just that this point has not been answered at all, but Ling Han, who was watching the excitement on the side, seemed to be very interested in this thing, and said curiously: "Is it possible that we can directly use chemical materials to corrode the exterior of the thing and take out the things inside?"

If only it were so simple, Ding Fan had also thought about it before, and directly used strong acid to corrode the appearance, leaving only the middle part.

But after all, this matter only stayed at the stage of conjecture, and was killed by himself, because to do this, it requires a high degree of control, and if you are not careful, things may directly destroy the core things.

This was bought by Wang Jianguo with his life, and Ding Fan said that he couldn't say that it would be ruined like this.

Even Zou Linong felt that this method was a bit risky, shook his head and said: "No, this method is too dangerous, as long as we have a little other hope, let's put this conjecture back!"

From this point of view, Ding Fan is the same as him, but if there is a way, this dangerous method is still better if it can be used.

As for other methods, we still have to wait for Zou Linong to think about it, after all, this old man is an old professor, and he may have experienced these things before.

"Grind off a layer of skin and see if you can find a bit of the internal structure inside. As he spoke, Zou Linong began to find his tools in the drawer, and said in a somewhat hurried voice: "It may take a little longer, and it may have to wait a little." ”

Originally, Ding Fan thought that Zou Linong had reached out to do it, who knew that everything was ready, the old professor actually stood up directly, handed over the things to Ling Han beside him, and said that he was going out to make a call.

This old professor just said that there was nothing to do today, but how long has it been in the blink of an eye, and he actually said that he wanted to go out?

Fortunately, someone is helping with this matter, and he doesn't have to worry too much, as long as someone helps deal with it.

And Ling Han seems to have done this kind of work often before, for these tools in his grandfather's hands, he can't be familiar with them, he prepared everything after dividing five by two, stood in front of Ding Fan and asked, "Have you thought about it?"

After speaking, before Ding Fan could respond, he had already begun to wave the tools in his hand and stretched out his 'poisonous hand' at the fixed teeth.

After a harsh grinding sound, the originally smooth white porcelain teeth were instantly worn off, and the surface was no longer smooth, but a little pitted.

"It's ...... Sure enough, there was something in there. Just rubbing the outer layer, the tool in Ling Han's hand had already stopped, and he looked at the things inside in surprise, and the whole tooth seemed to be slowly dissolving.

This is still her eyes with professional magnifying glasses, and she can clearly see that the lines inside, like capillaries, are broken one by one, blending the liquid inside with each other, and finally a chemical reaction occurs.

And in front of Ding Fan's eyes, it was different, in his opinion, the whole tooth actually began to melt, who would have imagined that a minute ago this was still a white ceramic tooth, and in the blink of an eye, this thing has been corroded.

If it weren't for Qin Lu pulling him all the time behind him, Ding Fan would have rushed over and snatched things back by now.

The inside of the denture is most likely hollow and there is nothing in it.

But who can be sure of that?

Anyway, it's never certain now, because the thing has been destroyed, and what's inside is far from a mystery.

"What happened?" Ding Fan looked at the corroded hole on the table in disbelief, and asked Ling Han in surprise, "What have you done?"

And Ling Han was even more surprised, his eyes widened, and he said a little guiltily: "I'm sorry, I really didn't mean to, the tool has been a little long, and the position on the edge is a little leaky, just shook it, and the middle position is a little deeper, it seems to have scratched the things inside." ”

In fact, this question itself is a little accident, Ding Fan knows that Ling Han cannot be blamed for this matter.

Professor Zou Linong is not too young, and the reason why he called his granddaughter to help is because the young man's hands are more stable, and no one thought that this equipment is a little old, and there will be leakage when using it.

Seeing that tears had begun to flash in the corners of Ling Han's eyes, Ding Fan held back the anger in his heart, shook his head vigorously, waved his hand, and said with a smile as much as he could: "It's okay, I don't blame you for this matter, no one thought that this thing would make the countermeasure so close to the surface." ”

At the beginning, when Ling Han made his move, Ding Fan had actually noticed her movements, and his hand trembled, in his opinion, it was not a problem, and if he shook it, it was at most a hundredth of a millimeter deep.

But it was this hundredth of a millimeter recess that eventually led to the erosion of the entire tooth.

When this thing is made, it is meant to be mounted on the teeth, imagine that if this thing is a little accidental, it may kill someone?

Looking at the hole in the table, you can imagine how corrosive this thing is.

Just when Ding Fan looked at the loopholes on the table and was almost helpless, Ling Han seemed to have made a decision, put down what he was doing, and said: " I just saw the structure inside, in fact, when the inside was made, it was left in advance, and the airways, just like the blood vessels in our body, in the airways, there are also insurance-type chemicals, after the two agents are mixed, a corrosive chemical reagent will be produced, so things can be corroded, if that's just the case, I think I have a way to deal with it. ”

Just as Ling Han was about to continue, Professor Zou Linong walked in from outside.

And he seemed to know everything that had just happened, and said with a slightly ugly face: "I know what you are thinking, but your research has not been completely completed, I'm afraid you are not completely sure, right?"

Ling Han nodded silently, and said a little embarrassedly: "My mother's experiment has reached a bottleneck, and if you want to make a breakthrough, it is estimated that it will not be a short time, but if you want to achieve rapid freezing, there is only this way." ”

Blast freezing?

As soon as Ding Fan heard this name, he immediately reacted in his mind, Ling Han just wanted to put the ceramic tooth in his hand into the freezer, and use the ultra-low temperature to completely solidify the liquid in the airway, and when the time comes, as long as he gently taps the ceramic outside, the liquid separated by the airway will not fuse, and the things inside will be safe.

It seems that this method is also a bit feasible, but there is one problem that has not been completely overcome, that is, the liquid in the tooth itself has not been determined, how to determine whether it has been coagulated?

I think Zou Linong also had this idea, so he didn't agree with this idea.

"I just went out on the phone and got in touch with a friend from before me who helped me find out how this tooth was made. Zou Linong looked at his table a little distressed, and finally sighed and said: "There are only three people in my country who can make this kind of thing, and there are very few people who can do this kind of craft, two of them we can find, and the other one has disappeared a few years ago." ”

This is definitely the best news for Ding Fan in recent times.

But good news often comes with bad news, Zou Linong looked at the curvature of Ding Fan's mouth that was about to be curled and suddenly said: "Don't be happy too early, these two people should not be the people you are looking for, because these two people are probably not capable of making such a delicate thing, after all, age is here." ”

As soon as Ding Fan heard this, the little curvature that had just curled up at the corner of his mouth disappeared in an instant, and for him, it was like a bolt from the blue.

Although there is no original author, there is still a way to open things, but it is a little dangerous, and it is a little more risky.

But when he can't take risks, he still doesn't want to take risks.

"Is there no way at all?" Ding Fan looked at the things in his hand a little lost, thought for a long time, and finally hesitated and said, "Can it only be frozen at low temperature?"

Zou Linong nodded slowly, reached out and took a ceramic tooth, and thought for a moment: " We can only try it now, if you can wait for two days, I have already asked someone to look for it, after all, there is still a person who will make this thing, if there is really no way, I also do not recommend you to use the method of low temperature freezing, because I asked, the preservation space inside this tooth is not very large, the things put inside, even if it saves important information, it is very likely to be just a camera negative, this thing, once the low temperature or high temperature, is likely to be destroyed, and when you get it, it is a pile of useless ashes。 ”

originally thought that the closest clue to him was this tooth.

Who knows, it is so difficult to get this clue that is close at hand, the only possible maker is gone, and if you want to open the mechanism above, there is a very high danger in the middle.

What is this called?

The current case may also be the most complicated of all the cases Ding Fan has solved so far.

There were so many things around it that for the first time he realized that his brain was a little underwhelming, and it seemed that it was time to recharge his batteries.

Just when Ding Fan already wanted to give up this line, Zou Linong suddenly said: "Maybe we can find another way, just think of this as a lock, I can help you find two lock-picking masters, maybe they can help us find some way." ”

Lock?

Don't say it, after Zou Linong said this, Ding Fan really felt that this thing was a lock.

It's just that the general lock has a keyhole, as long as there is a keyhole, no matter who can open it, but the so-called 'lock' in front of you doesn't seem to even have a keyhole.
