But very soon, these people each held a small piece in their hands.
And when they got it, they were puzzled, turning it over and looking at it again, but couldn't see any clues.
Of course, after all, there were over a hundred people present, and some did notice something.
As these people discovered the clues, a gasp of surprise quickly spread through the venue.
Word of mouth spread quickly; in just a moment, everyone in the venue noticed the oddities of the object in their hands.
However, you don't realize it without looking, and it's a shock when you do.
Wow, these little things can actually be taken apart.
And even with careful observation, the naked eye cannot see the joints at all.
This craftsmanship is enough to meet the requirements of super precision workpieces.
But that's not what shocked them the most. What was most shocking was that none of these little things were the same.
Some even featured extremely difficult asymmetrical joints.
