Well, if you add Tia's age from her transmigration to regression and her current life, she a granny already hahahha
Welp I read the novel a long time ago and this maybe a spoiler I dunno but Tia's mother side had some ability kind of and There's this thing that Tia might not actually went back to the past and had a second life but she saw the future and change it. ╮(￣▽￣)╭
Then that will make the going back in time make sense, I hope so.. Thanks for sharing what you read on the novel
Damn She defeated by kids lmao
