Krystal is the discoverer of this quasar. Krystal still remembers that time, when he first entered his father's research institute, perhaps because his father thought he was too naughty and did not let him affect his work, so his father gave him a technically processed card. After that, he told himself that if he could find the fifty hidden light spots on it, his father would take him to the playground on weekends.
But Krystal searched and found only forty-nine. That remaining spot of light could not be found anyway. In order to allow his busy father to take time to take him to the playground, the young Krystal sat on the ground unwilling to admit defeat, and searched for the photo for an entire morning, line by line, pixel by pixel. A pixel search. Finally, in a corner of a certain row and a certain column, Krystal found a light spot that was slightly brighter than the surrounding pixels.
