Barrier

Alex and the others were standing next to the riverbank, staring at the glimmering barrier in front of them. The river was a small and shallow one, but the problem laid on the barrier existing before them. After all, Alex and Ardeth had seen first hand how strong the barrier was.

Realizing Alex was standing still, Tiffany was puzzled, "What happened, daddy? Is there something wrong?"

"Aaah…" Alex was speechless, scratching his head in frustration, as he didn't know how to explain about the situation to his daughter.

Previously, it was Cerri who opened the barrier, letting them enter the garden. And now, Alex was not sure how to get past it. 

A thought suddenly flashed in his mind, as Alex turned towards his lovable daughter, his eyes shining. "Tiff, when you first came here, how did you get in? Do you happen to know how to open the barrier?"
