WHAT! I Have To Kill Heaven's Son To Live!

Reon, a lonely individual living a life of quiet monotony, finds himself unexpectedly transmigrated into a novel he once read. His transmigration was triggered by a complaint about the Protagonist. Instead of a prominent role, Reon is thrust into the position of a background villain, a mere expendable character with a single line of dialogue, designed only to showcase the hero's power. He's a spineless lackey for a spoiled young master, fated to die ignominiously before the main story even begins. Refusing to accept this cruel fate a second time, Reon resolves to live this new reality to its fullest, embracing the fantasy world's magic, swords, and cultivation. He plans to fight, love, and seize his happiness, manipulating the story's fabric and the protagonists themselves to achieve his goals and survive. However, his plan is complicated by the arrival of the Heaven Plundering System, which imposes a new condition for his survival: he must kill Heaven's Child. The novel features a domineering, intelligent, and alpha protagonist who is cold to outsiders but devoted to his loved ones, alongside strong, intelligent, and loyal female leads. The story will include a large harem with capable members, significant plot development, and R-18 scenes marked as such.
