Beginning by Reclaiming Seven Hundred Million: Transmigrating to the 70s with a Space

A heads-up: The protagonist is a "Saint Mother" type; proceed with caution if you dislike this.

Hua Wanchi was reborn and avenged her previous life's grievances.

Then, in her dream, she saw her deceased grandmother.

Grandma: Do you want to come find Grandma? Grandma can give you a spatial dimension, oh.

Hua Wanchi: There's such a good thing?

Then she transmigrated again.

Following the usual transmigration trope, before transmigrating, she used her money to hoard a full stock of goods.

Upon opening her eyes, she had transmigrated into the body of the little granddaughter of the old Hua family in the 1970s. Her paternal grandparents doted on her, her parents loved her, and even her paternal uncle and aunt showed her an extraordinary partiality.

Then she discovered that Grandma was the previous generation's female protagonist who hoarded goods in a spatial dimension.

Alright, alright, so she's making her walk the path she was going to walk, leaving her no way out, huh?

Then she's going to start taking the space planting route!

Wait, aren't you just one spatial dimension?

How come there's also a tool spirit?

Who can tell me how there's also a sign-in and lottery system?

What? Golden fingers can also be wholesaled?

What should I do if my tool spirit ancestor can even hand-make golden fingers?

Enjoying a cheat-like life with tears in her eyes!
