"Is this the two hundred million Conch Coins you were talking about?"
Yang Yi looked at the high-tech instrument, which was almost as tall as a person and connected to several monitors displaying a wealth of parameters.
"Quiet.
This microscope costs more than two hundred million. It's far more advanced than the one I was going to redeem. Its precision is on a completely different level, and it can produce three-dimensional images..."
Su Na never took her eyes off the computer screen as she answered, so Yang Yi went over to look too. He saw an extremely complex three-dimensional structure on the screen.
Su Na was trying to draw this cube, and she had already produced a rough sketch.
Yang Yi glanced at it. It already had something of the Perfect Cube about it. Although it fell short of the one he had seen on the phone back then, it captured a little of its essence.
"This cube has a very unusual structure. It's extremely complex. No matter what angle you divide it from or how you join the pieces together, its shape remains the same as the original. It's simply inconceivable.
For a two-dimensional example... joining two rectangles with matching side lengths still produces a rectangle, and its length-to-width ratio remains unchanged."
Su Na explained, but Yang Yi had seen a similar structure before, so he wasn't surprised.
He was only worried that studying the Perfect Cube might lower Su Na's Sanity and drive her mad.
Fortunately, that concern proved unnecessary.
Su Na was now more mindful of her Sanity than anyone else, because the moment it dropped below 50, Cui Xiya in reality would feed her a Sleeping Potion, completely ruining her research plans.
Besides, studying the Perfect Cube actually caused very little Sanity loss, because this electron
