Just as Lina and the others were trying their best to perform the song without proper conditions, suddenly, arrows like LED lights appeared on the ground in front of them. The people in the shelter were amazed, and even Lina and the others didn't understand what was happening.
The voice of Nan Ma resounded in the shelter, "Go on, girls, let more people hear your singing."
Curious and excited, Lina and her friends followed these lighted arrows out of the shelter, only to encounter something even more unbelievable: a crystalline floating staircase stretched step by step into the sky, and halfway up there was that gorgeous stage from their previous concert, with countless colorful lights decorating the stage like a dreamland.
