"Is there really such an amazing thing?"
Mu Jinjing's eyes widened, a little disbelieving.
But the shopping guide looked at her with a serious face, and nodded carefully.
"It's true, miss, if you don't believe it, you can take one of your things out and test it."
"Well, that's fine."
Mu Jinjin is a girl who is greedy for freshness, and when she heard that the shopping guide had a fun introduction to herself, she became interested, and found a bunch of keys from her handbag and handed them to the shopping guide, wanting to see if the machine was accurate.
She had been given the keys to the locksmith two months earlier, and she had seen them cast for her with new iron, so she was sure the keys would not be more than two months old.
If the machine shows more than two months or less, it means that the shopping guide is lying, otherwise the opposite is true.
The shopping guide took Mu Jinjin's key and put the key under the lamp port of the test machine, which immediately emitted a yellow light, and a black and white report popped up from the exit of the machine in a few seconds.
The shopping guide took the report that was still a little feverish, walked back to Mu Jinjin, handed it to her and said with a smile.
"Miss, can you see if it's accurate?"
"I'll see."
Mu Jinjin took the report and turned it to face himself, then looked down at the content of the report, and found that in addition to the black and white light transmission of the key, the report also wrote more than ten kinds of key materials.
For example, the metal iron accounts for 70 Copper accounts for 20 Aluminum-zinc accounts for 2 Magnesium accounts for 036 and so on.
The last line of the table of materials is written about the time of the metal, about 60 days.
Mu Jinjin looked at the 60-day data on the report form, which was a little incredible.
I really didn't expect that technology would reach such a point that even the key can be tested at a certain age.
It seems that she is really too far behind.
Mu Jin thought about it and suddenly remembered his bell.
She had always found the bell strange, she had never seen it before, the outer shell was transparent blue-white, and the beads inside were pale pink, and she didn't know what it was made of.
Now that she has such a good opportunity, of course she can't waste it.
Mu Jinjin lowered his head and found the bell from his handbag, handed it to the shopping guide, and said obediently.
"Can you test this bell for me again?"
"Yes, miss."
The shopping guide took her bell and walked to the testing machine, put the bell at the mouth of the testing machine and pressed the start button.
Like last time, it didn't take long for the report to come out.
The shopping guide took the report and handed it to Mu Jinjin.
Mu Jinjin was excited, and hurriedly reached out to take the report, and was about to say thank you to the shopping guide, but when he looked down and saw the age of the bell, the words he was about to say instantly choked in his throat, and the whole person froze in place when he looked at the number on the bell.
More than 6 billion years How can it be.
This tester is broken Mu Jinjin looked at the material synthesis table of the bell again, and the paper in his hand almost didn't fall to the ground.
Diamond 40 Unidentified material 60.
"Miss, what's wrong with you?"
The shopping guide saw that she looked distracted, and couldn't help but call her.
Mu Jinjin was stunned for a moment, closed the report in his hand and stuffed it into his handbag, found his wallet and prepared to pay, and asked the shopping guide calmly while looking for money.
"By the way, do you know what an unknown material is?"
"This test machine contains the names of all the elements of the earth, and if there is an unknown material, it means that the thing does not belong to the earth."
The shopping guide replied. oshow7 t1706231537:
