MTL - Great Voyage: the Strongest Clone System - Chapter 237

I’ve took the role of ‘that person’ who passed away long ago, someone who bears a striking resemblance to her. In a reverse harem fantasy novel set against a military backdrop, the title “Four Crazy Guys Obsessing Over Me,” or simply “F4,” unfolds. The narrative centers around the protagonist’s first love and former comrade who descended into madness following their demise, now fixated on the female lead. However, as the one who has taken on the position of ‘that person,’ I enjoy certain privileges. Could it be that my fate involves facing death? Alternatively, survival might lead to a twist in the romantic plot, with me becoming the object of obsession instead of the female lead. Personally, I’m not inclined towards being the center of such fixation. But then… “Hey, get your act together.” “The loser falls behind and gets left behind!” “These fools need to snap out of it! Can’t they get their act together?” Romance is nowhere in sight; instead, the harsh reality of the real K-military awaits me! Before I can fully escape this predicament, I had hoped that the male leads would become obsessed with me. However, this apocalyptic world consistently shatters my expectations. To worsen matters, it appears that the male leads are gradually losing their sanity in this chaotic world. What’s the only way to break free from this absurd exploitation? Naturally, it’s through a revolution! You corrupt imperial scoundrels!
