Ten Million Years Stuck in The Multiverse's Back-Up Information Centre

Kaori Sol spends about 10,000,000 years stuck in a space filled with light dots with information from all life (including different universes; some advanced, some behind).
......
After getting expelled from her family and being homeless, she almost died on the streets from sickness and hunger. Due to her high fever, she doesn't remember what happened afterwards but woke up in an emergency room. According to the doctor, she was found in front of the hospital half-dead. After that, Social Services took her in, and she got put in an orphanage.
After going through a hard and exhausting life, Kaori dies at 28 and finds herself in a space filled with lights. She finds out that once she touches the light dots, information poured into her head. Due to extreme boredom while being stuck in the space, she starts learning the information she gets from the light spots.
While absorbing the information, her body and mind goes into a meditative state. This means that she had no concept of time. Due to this, she didn't know she spent 10,000,000 years in the space.
After, 10 million years, she finally gets expelled from that space and finds herself reincarnated in an ordinary family in a different universe.
With all the knowledge she has gained from absorbing all the light spots in the space, watch how Kaori, the smartest person in the universe, navigates through life like a boss.
