Western Fantasy: After Unlocking Cthulhu, He Deceives the Male Protagonist and Steals the Female Protagonist.

The day I traveled through time and became a villain, the system told me: You only have one year to live. My name is Klein, a notorious playboy in the Kingdom of Nia, and a tool villain who could not survive three chapters in the original book. I was targeted by the Son of Destiny at the beginning. His woman treated me like dirt, and his sword was ready to pierce my throat at any time. The system said: Want to survive? Simple. Attack the girls of destiny and plunder their luck. Kill the children of destiny and take away their destiny. So I started to lay out—— Plant the seeds of doubt in the saint's heart and let her tear apart the illusion of perfect love with her own hands; I reached out to the Paladin when he was most desperate and made him kneel on the mass grave and beg me to protect his women and children; In the bloody dawn at the border, let that skinny boy sacrifice his life in exchange for his loyalty to me. Everyone thinks I'm a good person. Only I know—— I've never been a savior. I'm just an ordinary person trying to survive. Until that day, I saw that thing deep in the temple. Countless tentacles surged from the shadows, and billions of eyes opened in the darkness. It stared at my right eye, smiled and said: "Give me your eyes." My right eye started to change. Nebulae swirled in the depths of his pupils, and tentacles swam under the whites of his eyes. I can see three seconds into the future, and I can also see things I shouldn't. The system's voice sounded: "Contamination levels are increasing. Estimated survival time: one year." One year is enough for what? Enough for me to climb to the top of power, enough for me to sleep with the most beautiful women, enough for me to step on those who want to kill me one by one.
