“Miss Riddle has a point. Some things just can‘t be seen, but that doesn‘t mean they don‘t exist.” Ike
agreed with what Nicole said.
“Feel the surrounding walls,” Nicole said. The three split up and felt the walls. As the wall was also
white, it was impossible to tell what was in the walls by just looking with the naked eye. So they could
find clues by touching them.
Nicole gently pressed the wall, and a layer of stairs appeared out of thin air in front of her. She stepped
on it and pressed again at the top. Then there was another layer of stairs. She had found the pattern
and continued doing it. Before long, she had reached a height of about one and a half floors.
Meanwhile, Ike also found on his side the same stairs that Nicole had found.
“You‘re all up there. What can I do?” Harvey looked up at the two of them above.
“You keep looking for clues down there,” Nicole said.
Nicole reached up and came into contact with a square brick that sank in. She looked inside and saw a
glowing object. She pressed it, and a beam of light shot out at the brick in front of Ike.
“Put your hand on the brick with the light spot,” Nicole shouted to Ike.
Ike put his hand on the brick, as Nicole said, and inside was a prism mirror. He adjusted the angle of
the prism and the beam was refracted to the wall in the middle.
“See there? We need to get there,” Ike said to Nicole.
Nicole could not take her hand off now, or the beam would disappear. So she looked down at Harvey.
“See if there are any clues on the ground, Harvey.” Harvey looked carefully at the ground. “There‘s
nothing.”
“There‘s nothing?” Nicole fell into thought.
“There‘s a square tile with a pattern here!” Harvey shouted.
“Step on it,” Nicole instructed.
Harvey stepped on it, and the bricks fell off. He lost his balance and fell to the ground, one foot stuck
into the hole left by the brick. Nicole and Ike were shocked, and both thought Harvey had injured his
foot.
“Are you alright , Harvey ?” Nicole asked nervously and was about to get down from above to check on
him.
“I‘m fine. No need to come down.” He calmed himself down, slowly pulled his right foot out, and stood
back up.
A small trap scared the daylights out of Harvey and Ike. Nicole was surprised but not frightened.
“Stop stepping on the patterned square tiles. Check if there are other styles of square tiles?” Nicole
said.
Harvey looked ahead. “There , in front of the patterned brick, is a round brick.”
“Don‘t you step on it this time? Try pressing it with your hand.”
Harvey went over and squatted down, pressed hard with his hand, and the square tile rose from the
floor to a height.
“Find the same pattern and put your hand on it, then walk over to the square tile the beam is shining on
and press it,” Nicole said.
Harvey followed Nicole‘s instruction and pressed on the tile that formed an S–shaped passage below.
He came under the square tile that the beam was shining on, and with a gentle press, a door appeared
out of thin air on the white, gapless wall.
Harvey was going to open the door, and surprisingly, saw a four–digit combination on it.
“There‘s a four–digit combination lock.”
Ike observed for a while and shouted to Harvey, “How much time did it take us to get from the first level
to here?
Harvey glanced at his watch. “Twenty minutes and thirty four seconds.”
“Try entering that number!” Ike shouted.
Harvey entered the numbers and pressed, but the combination lock did not open. “The code isn‘t right.”
