Millie wasn't actually panicked at all.
Before she was captured, the Deer Leader had mentioned to her... if she got caught inside the Tianen Group, there was no need to panic. Someone would eventually get her out.
So she directly claimed she was simply testing the new drone she had acquired.
This excuse could actually hold up. Because the drone really was new to her—specifically, she had just gotten it three days ago.
After pestering her father for a long time, she finally managed to get a drone through legitimate and reasonable means.
Because her father was a Network Security Engineer at Tianen Group, he had directly handed down his retired "Gliding Spider" drone to Millie.
—In his view, this was actually to save money. After all, his daughter was just playing with it to practice her jumping technique.
