Atypical quick travel is just a setting.
You Lian was once a savior. She saved 99 worlds, but she could not save herself.
Once she woke up, she forgot everything and was forcibly set on everything, but she knew it was not true. She had a goal, but she forgot.
To achieve this goal, she once again embarked on the same but different path.
The copywriting is terrible and has little to do with the text.
The other heroine won't appear very early, but you said she is there and she is always there.
Intention: Break away from the shackles, just to be yourself
