"Right. If you guess it wrong, the escape won't be revealed."
"I hate this, but let me try. So you must have the hint, right? Give it to us," demanded Sikyung.
"The first pond. The hint is right there."
There is transparent number 1 at the top of the very right pond and makes everybody staring at the pond. As they saw it again, they just realized - as the other pond got covered by a transparent bubble with no color - this number 1 pond has a slightly blue transparent colored bubble.
"Oh, the color is blue!" screamed Sikyung.
"Hint for second, third and fourth pond," as the Sphinx says, transparent number 2, 3 and 4 appears at the pond next to pond number 1 respectively, "look closely for the hint."
The three of them stand up while grumbling then move closer - Daesun to pond number 2, Doyeon to pond number 3 and Sikyung to pond number 4.
"There is nothing..." complained Daesun while squinted.
"Once the other group finished with their mission, you guys, with the correct people, could enter the pond and exchange members. The escape will open when the exchanged people appear here."
"You keep your promise, right?"
"Sphinx would never lie. Especially if you win over their tricks."
