"Finally outside!" Yuan expressed his surprise, "I didn't expect that we stayed the whole night underground!"

As Yuan, Anna, Grace, Emma, Lily, and Xi Meili emerged from the ancient treasury, they were greeted by the sight of the sun high in the sky. They had unknowingly spent the entire night underground in their pursuit of treasures.

"Strangely, even though a whole night has passed, I don't feel tired or sleepy at all. In fact, I feel perfectly fine and brimming with energy." Lily muttered, as she wasn't feeling sleepy or tired after spending the whole night inside the underground ancient treasury without having any sleep. 

Anna nodded in agreement, "I feel the same way. Despite the intense battle against those grandmaster-level puppets, I don't feel a trace of exhaustion. It's as if I could run tirelessly for the entire day."
