Are You Blind?

  Su Ying told everyone to rise.

 "I believe that everyone has rested enough over the past few days. The second round of the test is actually not difficult. It will depend on your eyesight."

 Su Ying waved her hand, and the eunuchs carried a table over. On the table were three identical cups, and beside the cups were three balls of different colors, namely red, yellow, and blue.

 The young ladies looked curiously at the things on the table, and some of them could not help revealing a smug smile of confidence.

 In the capital city, there was a game that involved putting these balls into cups and changing the positions of the cups. After that, one had to guess which color ball was in which cup.

 Some of the ladies who liked to play looked at each other. They were already very familiar with the tricks of this game, so no matter what Su Ying asked them, they would be able to answer.
