"And if you can't move… just say the word. It will still work."
Their eyes widened.
"To make sure you understand…" Mu Ning said, raising her hand slightly, "Let's test it."
Warren and Gwen tensed. Still, they nodded.
Mu Ning lifted her hand and brought it down toward them, but they froze.
Neither of them spoke.
At the last moment, Mu Ning stopped. Her hand hovered just inches away from them.
A deep breath escaped her lips.
"…Again," she said more gently.
Her action made the two little ones relax subconsciously, and they both prepared themselves.
When her hand came down again, "Activate!" they shouted together.
A transparent bluish barrier instantly appeared around them. Mu Ning's hand collided with it.
Crack... a faint crack appeared on the barrier like a broken mirror, but the barrier held firm.
Warren's and Gwen's eyes widened in shock. "It worked…"
Mu Ning smiled. "To turn it off, just say 'Deactivate.'"
"Deactivate," they said together.
