First, there were changes inside the Pure White Mini Holy Grail.
When the female shop owner picked up the Pure White Mini Holy Grail, she saw ten strange little runes, with a black flame and red background, swirling inside the cup, growing larger and smaller as they moved about.
When they touched the walls of the cup or crossed the plane of the cup's rim, they vanished like castles on a beach obliterated by a 200-pound child, only to reemerge from the bottom of the cup. The number of runes always remained at ten.
Without much thought, Ren Suo immediately realized that this must be the visualization of the Desire Collection Amount. After all, the oddities of the Pure White Mini Holy Grail had begun to manifest after he had collected 10,000 Desires.
