Grandma just went to buy groceries, but unexpectedly she got on a time traveling subway. In 2060, grandma became a 19-year-old girl. In a future world full of fantasy, she has been upgraded from a small role to fighting monsters. The gods randomly selected the weakest one, but she didn't know that she would become the strongest in the end and help the heavens save mankind. Fantasy, cute, funny, light-hearted, no more spoilers. Finally, please vote. Various recommendation votes and monthly votes are acceptable. Thank you for reading!

Fall into a black hole and be reincarnated, return to your homeland, and start from the bottom.
