I Transmigrated into a Book Set in the Seventies. What's Wrong with Being a Little More Evil as Cannon Fodder?

After staying up all night reading a tragic period novel, Yan Bing opened her eyes and found herself in the body of a cannon-fodder character who shared her name.

Her stepsister pretended to be gentle, framed her for stealing parts from the steel mill, and stole the original owner's iron rice bowl. Treated like dirt, the original owner was forced to marry her stepmother's gambling-addict nephew, then was eventually handed over to a lecherous old man to settle a debt. She died after a life of horrific abuse. Yan Bing gave a cold laugh. This time around, she was going to be the villainess.

Her first act of retaliation activated the System and a portable space. Under the rules, the more miserable her stepsister became, the stronger Yan Bing's fortune grew. By accumulating Life Points and Emotion Points, she could keep expanding and upgrading her space.

Her stepsister's name was nailed to the neighborhood committee's blacklist.

She emptied out her stepmother's hidden fortune.

She bought rare seeds on the black market and planted them in the space, testing and cultivating them until she finally bred high-yield crops. The space continued to evolve, filling up with food, medicine, and all kinds of emergency supplies.

Her spiteful grandmother was left homeless, reduced to scraping by on the streets.

Her stepsister married a drunk, injured him, and was sent to the countryside for reform through labor.

The grandson her vicious grandmother treasured above all was actually the illegitimate child of her stepmother and her childhood sweetheart. The grandmother, who had always hated Yan Bing, sold off her stepmother's illegitimate son and bitterly regretted it, ending up begging on the streets.

Her hypocritical stepmother went mad from despair and hunger.

Others called Yan Bing ruthless, but the leader Cui Hao looked at her and said with a smile, "What's wrong with a cannon-fodder villain being a little wicked? I love her just the way she is!"
