Niken did not know how many memories of Flynn that she has seen. She felt somewhat guilty for having peeked into other people's memories. She hoped Flynn would not get mad at her after this.
After finishing intensifying Flynn's last happy memories, Niken returned to the empty space when she first came here. There was still nothing around, but the dominant color of the surroundings had changed.
Previously it looked gloomy gray, now it has changed to white.
The surrounding of a person's astral dimension usually indicates the personality of that person's soul.
The astral dimension of Niken, which was previously dark and lonely, was darker and colder than this place. At that time, her celestial soul was confined within her own dimension. Hence her astral world was empty.
Now that Niken has been practicing her energy cultivation, her astral dimension started to change to become colorful little by little.
