Apocalyptic Catastrophe: I Became Rich by Harvesting Villains

[The end of the world + sweet pet + double cleansing + plane trading + alien monster heroine + animal and plant mutation + superpowers] Xie Fei accidentally slipped into a post-apocalyptic novel and became a miserable cannon fodder for the heroine. At the critical moment of life and death, he was bitten by a alien monster, and accidentally connected to the "Plane Trading Mall" with a thick golden finger - not only can he trade materials across time and space, but he can also exchange for supernatural powers, and even... He can make transactions with non-human beings. The end of the world is difficult? It doesn't matter, she has supplies in her left hand and super weapons in her right hand, and occasionally sells some "black technology", so she can live a prosperous life without any morals. Until she ran into the group of protagonists from the original book who claimed to be "bright and just", and was surrounded by a group of people who morally kidnapped her and kept asking her to "hand over supplies and help others." Xie Fei sneered, turned around and joined the "rookie team" despised by the opposite protagonist without hesitation. Xie Fei was eager to seize power and become the captain, but she was caught off guard and discovered that the captain who always stared at her silently and with eyes as deep as night was actually the ultimate villain in this article who was the most hidden and planned every step of the way! And she not only whipped him and slapped him in the face, she also arrogantly said: "A man like you can sleep with you just by hooking your fingers!" Is it too late to kneel down and apologize and take back what I said? But he stepped closer, holding her against the wall of the ruins with a gloomy expression. His fingertips rubbed her whip-wielding wrist. His breath was hot and dangerous, and his voice was low and hoarse with a smile: "I've already been whipped, so why not just whip her like this for the rest of my life, and together we can turn this man-eating apocalypse upside down!"
