This young person was Ling Lan. In the Ling family's house, a loyalist with a similar body structure and voice was used to disguise as Ling Lan. The loyalist pretended to be her and laid in the healing pod. Little Four also left a replica of him at the house to oversee the security of the house. Even if someone from the military headquarters came, they wouldn't be able to see past the disguise.
This time, Ling Lan just travelled based on luck. She would point to a location on the map casually and visit that place. She didn't expect herself to come to Planet Muyang. She didn't even know about this planet in the first place.
The little girl's house was in a small town. It was a little far from the platform so the little girl brought Ling Lan onto a hover bus. The bus travelled for an hour before reaching the little girl's house.
