Li Bin'er nodded confidently, Lei Xiaoyu looked at Sister Bin'er's handsome and high-headed appearance, her eyes were shining, isn't this the temperament and imagination she wants? In the past in the village, every time she saw Bin'er like this, the problems and troubles encountered would be solved, and she could feel that this time Sister Bin'er would definitely be able to find a breakthrough in the clues! I don't know if it's the faith that comes from.

"Sister, come on! Let's go through them separately. ”

"Well, give me the Ninghai Delin reagent first." Li Bin'er walks on the left, Xiaoyu walks on the right, before leaving, Bin'er needs to use Ninghai Delin reagent, as long as this reagent is sprayed on the upper place where there are clues or thieves touch, its reagent will be on the sample, and it will immediately react with amino acids, showing purple fingerprints, and fingerprints need to be photographed or fixed by chemical methods immediately after they appear. In fact, in addition to using the Ninghai Delin method, you can also use silver nitrate, iodine fumigation, fluorescent reagent method, or other fingerprint electronic devices. There are many ways for the police to check fingerprints, and with the development of technology, most police officers use electronic devices, but there may be some glitches and inspection errors, so Xiaoyu chooses to use the old-fashioned method.

As soon as she finished asking, she saw Lei Xiaoyu stunned, and then shook her head helplessly, Bin'er reacted quickly, patted her head, and exclaimed, "Oh yes, hey I'm a little stupid today, just because I didn't ask just now!" ”

"Sister, just play with it, don't take it too seriously."

"Hmm." Xiaoyu walked away, and Bin'er rubbed her temples, "Why did you make such a low-level mistake today?" ”

There have been so many detective experts who have checked this place before, as long as they are not stupid, then they all know to use the fingerprint method, in other words, those gold and equipment are probably stained with a thick layer of reagents.

"So, the gloves used by thieves to commit crimes? …… Hey, no matter how much it is, I can't find it out anyway. Li Bin'er touched her chin, muttered to herself, and walked inside, planning to check from the alchemy field first, the place where the finished gold bars were placed in the main vault received too much attention, on the contrary, the alchemy field that produced gold paid little attention, and I heard that only a few experts came to see it. But 30 percent of what the vault boss loses is semi-finished gold.

There are more and more doubts, why do thieves still steal semi-finished products? Is finished gold bad? The cost of refining is not low, and if there are more impurities, expensive materials are required for extraction.

"Did the thieves steal it and then pick it up? …… Impossible! "Not to mention that it is very heavy, it has to be carried, and many substances in the impurities of gold are useless.

Come to the alchemy field, here is very closed, the space is large, but everywhere there are copper walls and iron walls, there are special smoke exhaust holes for smelting, and the workers also have special oxygen cylinders, so that there is no shortage of oxygen, these alchemy equipment is complete, huge equipment, and are all brand new white, there is no dirty feeling, a set of equipment is neatly arranged where, and sometimes several workers come out to work activities. I didn't expect that I hadn't been in contact with the alchemy industry for so long, and now it has developed to this extent.

They don't need to hire too many employees, cash equipment has been able to intelligently simplify a lot of manual work, robots and intelligent instruments have been able to replace humans to do a lot of work, and those workers' usual task is to check whether these equipment is working properly and whether it is working according to the planned degree of production.

Manual refining will only begin at the appropriate time, and as for the specific operation, it is up to the owner of this factory to ask.

"Are you here to check again?" A staff member who was all wearing long overalls walked over, and the first thing he said was something, this impatient tone made people feel very uncomfortable to hear, and Bin'er felt even more awkward, and couldn't help frowning.

"I came with the Coastal Police Station to investigate, did there anything unusual happen on the day of the theft?" didn't deliberately make it difficult for him, and asked truthfully, now he needs these clues very much.

The employee shook his head helplessly, was very speechless at the common problem, took off the oxygen mask, and said, "What abnormal feeling do I have, at that time, for no reason, the gold disappeared!" Eh, don't look at me with that kind of look, it's weird, it's not that I don't work hard, if I don't see it alone, you can say this about me, then all the personnel of the unit haven't seen and heard the movement!! Not to mention any anomalies! How do I know anything out of the ordinary! Do you think I want these gold and silver treasures to be stolen?? This time the boss went bankrupt, and our wages were reduced by a full half! You think I want to?! And these thieves can steal if they want to, and they will steal some unfinished products, these things are the lifeblood of our staff! If he steals the finished gold, the boss won't blame me! ”

The employee's accent was very strong, and his tone was incongruous, which made Bin'er have a hard time listening, but he still understood the general meaning, that is, he had no idea how the gold disappeared. Anyway, the finished gold is placed in several layers of steel walls, and this place where the gold is produced is equivalent to the back of the vault, which is also equivalent to the type of place in the backyard, but don't underestimate this place, it is closed in all directions, if you don't wear a professional mask or props, you will get lung cancer or other diseases if you stay in this place for a long time.

"Hmm." Responded to him lightly, this is trouble! Even the employees who have been here have not been able to provide any clues, and it is sad that those detectives will come empty-handed, and the great detective Mori Koshiro ran to check and then made a big fuss, saying that it is impossible to break through the case, and it is impossible to even find any clues. If he weren't a great detective, I'm afraid many people would think that he was "can't eat grapes and say grapes are sour!" ”。 Because the great detective Maori said so much, many detectives only shook their heads, saying that they couldn't complete this task.

Looking at which employee is rough all over, alchemy employees are almost like this, in addition to being hot stamping and baking every day, they also have to keep operating to complete operations such as importing molds, even if there is robot assistance, some tasks must be completed manually, otherwise the bronzing will fall to the ground, and the gains will outweigh the losses.

Looking in the direction he pointed, he was shouting that these unfinished gold were his lifeblood, and Bin'er saw that several large pieces of unfinished gold were standing on the tracks, uneven, or unrefined, containing a lot of impurities.

"What about surveillance??" Li Bin'er still won't give up the inspection, although she already feels in her heart that this is not destined to be a case that she can solve. In everything, whether it is success or failure, attitude is the most important thing!
