Douluo Dalu 2: The True God King - Chapter 136: [DD2]:

Waking up in an unfamiliar world with no memories, I had only one advantage—a mind filled with knowledge of fictional tropes, clichés, and common sense learned from countless novels.At first, I thought I was trapped in a romcom nightmare when I started triggering events like “Helping a Girl on a Rainy Day”, “Damsel in Distress”, and “Tripping Into the Heroine’s Arms.” Naturally, I shut those nonsense down before they could escalate. No forced romances. No misunderstandings. No cringe.But something was clearly off.The world wasn’t just a slice-of-life comedy.Beneath the cliché academy setting, there were whispers of awakening powers, hidden dangers, and a brutal magic academy entrance exam.And every challenge I prevented or manipulated was an opportunity to grow stronger.[Title Earned: Background Character.][Achievement Unlocked: Firm Mind.][New Skill Acquired: Background Character's Aura.][New Ability Acquired: Anti-Narrative Influence.]I may be just a background character, but if fate insists on throwing these events at me, I’ll turn them into stepping stones.Let the protagonists play their scripted roles—I have my own path to power.

Then, she swung her hand, and a large number of handsome men’s pictures were spread on the table.“Baby, be a good boy and choose someone you like to be your stepdaddy, okay?”Mu Tingfeng’s expression… turned dark.
