The Self-Cultivation of a Tool Person [Quick Transmigration]

Lin Qi found a job with the Alliance—playing the role of a disposable side character in male-oriented fantasy worlds. His tasks included, but were not limited to: ① delivering equipment to the protagonist, ② taking damage for the protagonist, ③ and ultimately dying to motivate the protagonist. Lin Qi diligently completed all his missions. However, after his death, every protagonist turned dark and destroyed the world. Protagonist: "A world without Qi Qi is meaningless—nothing but destruction." Lin Qi: "I didn’t do anything wrong..." The Alliance: "...Please, for the love of all, save these worlds..." And so, Lin Qi, equipped with a support system, was thrown back by the Alliance to before the destruction of those male-oriented worlds, forced to replay his role from the beginning. System: "Target’s favorability: 100. Corruption level: 100." Lin Qi: "Why? I haven’t even done anything yet?" System: "He has regressed..." Protagonist: "This time, I won’t let you suffer a single harm."
