"What is this?" said Rose, tucking the napkin in her hand, taking the loot from the crow, and looking at it, "as if it had just been fished out of the toilet." ”

"It's a metal pipe. "As for where it came from, I don't think you would be interested in knowing." ”

"So it's a metal pipe, thank you so much. Rose didn't even look at the crow, her eyes were always focused on what was in her hand, "Since you know it's a metal pipe, don't you need me to look at it?"

"Hahaha, what is a metal pipe, is there such a thing in the world?" said the crow, laughing dryly, pretending to be stupid, "It's so strange." ”

"Water. Ignoring the boring fellow, Rose took the water he gave him and wiped it on the metal repeatedly, and soon the sludge was wiped off, revealing a smooth metal surface. The rose tapped back and forth on various parts, constantly leaning into his ears to listen to the sound of metal, and after a long time, he frowned and said hesitantly, "A rare alloy, it is certain that there is titanium and gold inside, and what cannot be determined is that there are several other components." ”

"Tsk, it's amazing, you can analyze it by just knocking on it. The raven exclaimed, "How?"

"Are you sure you really want to know the process and the basis for the analysis?" said Rose coldly, "I don't mind going into details. ”

"Thanks, no need. The crow himself could make up for up to three hours of lectures on metal composition analysis, and more importantly, he was sure that after wasting three hours, he would definitely not understand anything, so he shook his head with Rose's expressionless face, "I suddenly don't want to know at all." ”

"Clever choice, and besides, you don't learn like it at all. Rose glared at the crow disdainfully, "So, show me what it does?"

With a "bang", the crow poured the pile of stinky metal parts in the backpack to the ground, "You see, there are many similar alloys, I think they are about the same hardness, they should be the same alloy." ”

"There are a lot of things with similar hardness. Rose chose a few random observations, "like your head and a hammer for a small bean." ”

"Uh, I found a problem. Although Rose usually speaks with such a personality, but the crow found that the current rose has a strong offensive personality in her words, and after thinking for a few seconds, the crow suddenly showed a suddenly realized expression, with an ambiguous smile, and teased, "Is it because I flirted with Boss Mi just now, so you are jealous?"

"Huh. A sharp gaze like a rose knife swept across the crow's face and showed an extremely dangerous smile, "How many times do you want to die?"

"Looks like I'm right. "Of course, the crow is not arrogant enough to think that Rose is jealousy in the usual sense, and by jealousy, he naturally refers to the jealousy that you are fighting with others even though you are my teammate, or rather, not jealousy but possessive.

"Hmph. Of course, Rose was also aware of her psychological problems, but she just snorted coldly, and she no longer entangled with the crows.

"There are a lot of things with similar hardness, but this time they are the same alloy. After replacing several parts in succession, Rose finally confirmed Crow's guess, "It should be on the same machinery, at least the same batch of machinery." And then, what else do you want to know?"

"I'm curious about this machine, and I want to know a lot of things. The crow pondered and said, "For example, the age of this thing, what kind of machinery is assembled, what is the purpose of the machine, what is the role of several parts in the machine, and under what environment can it be so well preserved." ”

"Nothing?" Rose waited until the crow stopped talking, and then asked with a cold face, "That's all?"

"Uh......" Seeing that Rose's tone was not quite right, the crow scratched her head and said, "That's all for the initial thoughts, is it troublesome?"

"Trouble?" Rose squinted her eyes and thought for a moment, leaned over to pick up a clod of earth, handed it directly to the crow, and said lightly, "Here, let's draw." ”

"Okay, I see. The crow was stunned for a moment, then shook his head with a wry smile and said, "I take it for granted, I'm sorry." ”

"What the hell are you guys doing?" said the leopard-sed, who had finally finished eating, wiping her mouth, dissatisfied with the leaping conversation between the crow and the rose, and grumbling impatiently, "Can't you say something that a normal person can understand?"

"Well, the cat is angry. The crow took the opportunity to resolve his embarrassment and explained for the female leopard, "I made a bunch of unrealistic requests, but Rose was not happy, and took this clod of earth and asked me to draw a topographic map of this area or the Liuqu grassland." ”

"Just kidding. The female leopard's eyes widened and asked, "Can you really draw it?"

"Nonsense. Rose said angrily, "Of course you can't draw it, and he's not a fairy." ”

"I really can't draw it, hehe. "She just told me around the corner, don't make such unrealistic demands to make trouble for her." ”

"You two are so interesting. The big cat looked at the crow, then at the rose, and said suspiciously, "Since when did you two have such a tacit understanding?"

"Huh?" The two smart people were stunned at the same time, thinking about it carefully, in the past month, the communication between the two has almost transitioned from a little bit between smart people to a point that is completely dependent on tacit understanding, if it wasn't for the female leopard to mention it, I'm afraid the two would not have found out by now. The two looked at each other thoughtfully, and Rose suddenly snorted coldly and twisted her head away, with an attitude that had nothing to do with herself.

"Hehehehehe. The crow pushed his glasses and said casually, "What kind of tacit understanding is this, it's just that everyone knows it, it's normal that you don't understand, after all, we don't meow." ”

"Meow you xx. The female leopard spared the table and lifted her leg with a kick, "Don't want to fool the old lady, the old lady can see it clearly." ”

"Do you want to listen to these metals?"

"Absolutely. The female leopard leaned next to Rose, sat down with her arm in her arms, glared at the crow defiantly, and then said with satisfaction, "Say it." ”

"While I probably can't do someone's almost requests, I can see something in the metal. ”

"First of all, the production time of these metals should be within a hundred years before the catastrophe, according to the maple leaf calendar, that is, after the thirty-eighth year of Emperor Zhuang. ”

"Well, that's right. The crow nodded approvingly, "It has been recorded in ancient books that the technology of the pre-disaster era developed exponentially in the last hundred years, and it makes perfect sense that this rare alloy appeared during that time. ”8)
