[DeepL Translation - needs review] Volume 1: "I Was an Old Man!"
Ren, an orphan girl, regains memories of her previous life on the way to being sold to a peddler.
In her previous life, Ren was a thirty-something male researcher, but she was reincarnated and lived as an orphan until now.
Ren survives in this harsh world by herself, making full use of her magical talent and scientific knowledge from her previous life.
