However, a hundred years is too long for such a dynasty to make no sense. Rose shook her head, "Further inference based on the level of science and technology, this kind of hardness alloy, to forge and cut them according to the required shape and thickness, and then to polish and polish, a very mature set of technology. And you see, this root, this root, and this root, the thickness, the length, the thickness, and the shape of the excuse, are all exactly the same, indicating that these parts are mass-produced products, and not made by chance. ”

According to these points, it can be temporarily judged that the manufacturing age of these parts is probably in the twenty years from the first year of Emperor Ding to the eighth year of Emperor Mourning, that is, the first twenty years of the catastrophe, and even during the catastrophe. ”

"See, idiot crow. The female leopard was as proud as she had said these words, and proudly boasted to the crow, "I said that Rose must be able to see something, she is very good, and she knows everything about this knowledge." ”

"Hehehehehe. The crow pressed her glasses, just smiled, and said nothing.

The female leopard is a simple and straightforward cat and never thinks too much, but the crow is different, he thinks a lot.

No one is born with these knowledge, and if you want to master them, you must go through a long and extremely boring study and study to be like a rose, and you can analyze it by tapping it casually.

Not to mention a busy mercenary, he is a stranger who has lived in the city all his life, has no great perseverance, and cannot endure the boredom and loneliness in the process of studying, but Rose must endure.

If you want to inherit Lily's legacy and grow up as soon as possible to be qualified to avenge Lily, the fastest way is to retrace the path that Lily walked back then.

Lily has been following the footsteps of her ancestors and exploring the secrets of this world, and only then did she vaguely discover the truth of the world, so the rose naturally has to follow closely so as not to be thrown away by the truth.

However, if you want to explore and discover, it is not like most people imagine, travel around, and then fight and kill people, and consciously jump out of the secret, this kind of good thing only exists in fantasy.

In fact, exploration and discovery, in addition to the need for strong strength to ensure their own survival, what is more needed is a large amount of relevant knowledge, without the support of these relevant theories, no matter how strong the strength is, it is like a blind eye, not to mention the clues from the clues hidden in the shadows, even if you put things in front of you, you may not know that this is the goal you are looking for.

Therefore, the crow can already vividly imagine that in countless dark nights, a teenage girl, while tearfully chanting her sister's name, while enduring sleep, repeatedly reciting relevant data under the lamp, in the shadow of the table, countless pre-disaster professional books are piled up, exuding an old atmosphere.

"Hehehehehe. The crow chuckled again, and smiled meaningfully at the rose.

"Hmph. The crow's smile made Rose snort, but this time, her voice was much softer, "Actually, you can narrow it down even further, I almost have the bottom in my heart." ”

"When will you use this alloy to make parts? That's the most critical question. ”

"This alloy is not common, and there are not many parts made of it, it is estimated that because its processing technology is relatively complex, it is not enough to replace civilian metals, and industrial metals cannot be replaced, even in military products, so where are they used?"

"Look at their metal characteristics, the first is high hardness, high hardness on the one hand is not easy to deform, on the other hand is anti-wear, which means that the precision of the machine is very high, a slight change may lead to the loss of use of the machine. Moreover, after the machine is put into use, it will be in a state where it is not easy to replace parts, so the hardness of the parts is as high as possible. ”

"Another characteristic is that it is inert, that is, resistant to corrosion and oxidation, it has been as good as new for hundreds of years, and it has been soaked in the digestive juice of giant earthworms for a long time without leaving a trace. ”

"This means that the parts are required to be able to adapt to most environments, acids, alkalis, and moisture, all of which need to work properly. ”

"Obviously, as with the first feature, this feature is designed to minimize the number of parts to be replaced and to extend the working time. ”

"With these two properties, combined with the approximate time of the metal's appearance, it is actually close to being inferred, and your guess is very likely, the metal is very likely to have come from some underground bunker. ”

"Sure enough. Raven frowned and said, "But I have another question, have you ever seen a similar alloy before?"

"The word mystery is not for nothing. Rose didn't answer.

The crow nodded, "Looks like you think they're from there, too." ”

"Hey. The female leopard protested, "You two are about the same." ”

"Tsk, the big cat is angry again, meow meow. The crow stopped flirting before the leopard was about to blow up and explained, "I asked her if she had seen it before, and she said no, and I asked again that even if this alloy was for the construction of underground bunkers, it should also be found in other underground bunkers, and she said that the underground bunker was a mysterious underground bunker, and I said that it seems that you also think this is from where we are looking for, and she said yes, I said meow ......"

"Meow you xx. The female leopard said with her teeth and claws, "If you want to speak in the future, you can say it well, who only speaks half a sentence, and the rest depends on guessing." ”

"Huh. Ignoring the big grinning cat, the crow said with a smile, "Since you also think they came from that mysterious underground bunker, then I think we have found a treasure." ”

"You mean the metal ball that Xiao Huo mentioned?" Rose's cold face was actually slightly moved, obviously the existence of this metal ball made her also very concerned, "Take it to me, the ball is a unique tool for storing important items in the Maple Leaf Empire." ”

"Here you go, Raven's Ball. The female leopard took out the orb she found from her package, "How about we smash it?"

"Smack. The female leopard immediately received a heavy slap on the buttocks, and the rose snatched the crow's ball with the same expression, regardless of the dirt on the surface, her hands groped on the surface of the metal ball and said, "It's this kind of thing, from small gold and silver jewelry to large heirloom jade seals, they all like to use this kind of thing to hold it." ”

"It probably has something to do with the culture of the Maple Leaf Empire. "When it comes to history and culture, it's the crow's specialty," the Maple Leaf Empire is prosperous with water, and the water-based cycle is reciprocating, so the circle representing the cycle has always been the symbol of the Maple Leaf Empire, and after the three-dimensionalization, it is the sphere. ”

"Well, that makes sense. Rose nodded, "I'll tell you something else, it's the same material as those parts." ”
