Return from Rebirth: I Defected to My Ex's Arch-Enemy

[Rebirth and revenge + strong woman + cool story about scumbag abuse + chasing wife in the crematorium] * I died in the winter when I was thirty-one. In a dark, damp, moldy cell, he breathed his last in endless pain due to acute renal failure and sepsis. The news of the death was announced by Gu Tingxiao himself. He looked at me coldly through the cold iron bars. "Not only did you embezzle public funds, you also tried to blame Wan'er. A vicious woman like you should die in prison." He said while adjusting his sleeves, like a calm killer, baptizing himself after completing the killing. Beside him, the woman named Ling Wan'er raised the corners of her mouth slightly, and there was a trace of pride that only I could see in her big, innocent eyes. I laughed so hard that it hurt my heart; I coughed, coughing up the last bit of blood that was suppressed in my heart. I have loved Gu Tingxiao for ten years. From having nothing, he founded "Oracle" and established his own technological empire. Countless all-nighters, countless banquets, and even the knife I took for him, the scar is welded on my white back. I thought we were allies fighting side by side, lovers who trusted and relied on each other the most. But all these are not worth a drop of Ling Wan'er's tears. She was his "sister" who was separated in the orphanage, the only hope in his barren childhood, and the light that he couldn't catch in his nightmares. And me... At the last moment when my consciousness dissipated, there was only one thought in my mind - if I could do it again, I would... I would definitely pay for it with their blood. Take one more look at me, remember my appearance, and... My name, I... Am Su Nian... I'm back.
