Although the invisibility charm was always being broken, it was still very effective in front of ordinary people. At least the security guard didn't know that a little one had floated into the Orphanage right in front of him.
Besides the invisibility charm, to make her movements soundless, Mianmian also used a Magic Carpet Talisman.
She moved through the Orphanage.
Without any visiting guests, the Orphanage was particularly quiet.
The doors of each room were closed, and the lights were out, pitch black. Fortunately, Mianmian could see clearly at night using her Heavenly Eye.
She entered each room through the windows, avoiding the patrolling staff, and carefully searched the rooms.
But this was too inconvenient.
If there were any secret passages or the like in the rooms, they would have to make noise to be discovered.
She thought for a moment, then had Ayu help her: "Ayu, you can pass through walls, help Mianmian see if there's anything strange below."
