Rebirth in the Apocalypse, I Return with the System and Kill the Scumbag with My Own Hands

[System + upgrade + heroine's revenge + apocalypse] In my last life, when the apocalypse came, I, Wen Le, was betrayed by a scumbag. He was holding his stepsister and child in his arms, and I was like a stranger. Zombies poured into the corridor like a tide. Shen Chuan looked at me coldly, pushed me directly to the bottom of the stairs, and closed the iron door heavily. "Sister, just help us." "Actually, this child belongs to Brother Chuan from beginning to end." "You are not the son of the bully downstairs at all. All the supplies you worked so hard to hoard should belong to us, mother and son." His whole body suddenly stiffened. The blood in his body seemed to freeze instantly, and his limbs were cold and numb. It turns out that from the first day Wen Qing came to me, it was a carefully woven scam. At first, Wenqing ran away in embarrassment, crying and ran to my door to take refuge, crying with tears in her eyes. She said that in exchange for a bite of food, she was coerced by the bullies downstairs and became pregnant unexpectedly. She was born in a pitiful background and had no other choice. At that time, I was soft-hearted and guilty. I felt sorry for her being humiliated at such a young age, so I took her in without saying a word. I looked at the child who had been raised with care by me, and at the two people hugging each other tenderly inside the door. The heart is as gray as death, and all thoughts are gone. The iron door was completely locked, and without looking back, they walked up to the roof step by step, abandoning me to hell. Shen Chuan, tenderness, if there is an afterlife, I will make you pay with blood, and you will not die a good death!
