The 1970s: The Garbage Merchant of the Planes

Old mechs, old flying swords, old hovercars...

Marrow-cleansing pill residue, beauty pill residue, secondhand low-capacity storage drives (100T)...

Yu Jian: Buy, buy, buy!!!

One-line summary: She turns trash from interdimensional planes into a business, and makes a killing!

[Because of the controversy over the female lead's conduct, and because some readers have misunderstood the plot by getting the order of events mixed up, I'll leave those points aside.

A few words up front: Yu Jian is cold-natured. She always puts herself first, and selfishness is part of who she is, but she isn't purely selfish. She simply has little sense of emotional attachment and always considers herself first. She is used to judging others by herself.

After she transmigrates, her surroundings are completely unfamiliar. She has no memories of the original owner, feels little attachment to her new environment, and doesn't know what her eldest sister-in-law is going through.

Even by the end, she still doesn't feel much for these "relatives." That's just her nature. She only pretends to get along with people.

But sometimes she does soften. She helped her eldest sister, second sister, and even her eldest sister-in-law escape their initial predicaments.

She has repaid what she owed. She owes no one anything.

There's a plot point later involving a trash lucky bag, which has also been controversial. The description of the item itself didn't promise anything. The soil and secondhand plastic toys were planted clues: in theory, they were useful, especially to certain planes, and unusual enough to sell for a good price. The plane that bought them didn't need them, but could dispose of them properly and prevent environmental pollution, which was also a good thing. I simply forgot to write that part later, and that's my mistake. I wanted to explain it here.]
