Villain: Ultimate Mutation System in the Alternate World

"I despise this world. I despise everyone. There's no justice for the weak." Once, Reign lived a life filled with joy and freedom. But his existence took a dark turn when he was kidnapped and subjected to brutal experiments. These ordeals not only ravaged his body but also shattered his mind. Ultimately, his body couldn't endure the torment, and he died like a pitiful lab rat. But death wasn't the end. He awoke in a new world as a corpse, equipped with the Ultimate Mutation System. This system allowed him to mutate and gain power at the cost of his humanity. Determined to avoid exploitation again, he resolved to become an unstoppable force. He knew that weakness would only make him a target, especially now that he was a monster. "Kill or be killed." That was his only path. Disclaimer: No NTR No Yuri Focus on the plot
