Maou-sama no Machizukuri! ~Saikyou no Danjon wa Kindai Toshi~ - Volume 1 Chapter 18

MAIN CHARACTER GET TRANSFERED TO ANOTHER WORLD WHERE HE USE TO INCREASE CULTIVATION OF HIS WORLD

In a world where failure is almost guaranteed, the game I now find myself in has a staggering 99.9% chance of defeat. Every choice brings chaos, and every road leads to disaster. No one has ever beaten it—it's infamous for being impossible to clear. But somehow, against all odds, I've transmigrated into this cursed game.Worse yet, I've taken over the body of Max, a minor character whose role is insignificant in the grand scheme of things. In the original story, Max is destined to die—nothing more than a forgettable extra lost in the background, a mere footnote in the epic tale of others.Frustration hit me hard as I realized I was trapped in this dead-end character. My doom felt inevitable, and every instinct told me to give up. What hope did I have in a world where even the strongest could barely survive?But just as despair was about to swallow me whole, a System suddenly activated, turning everything on its head. Along with the System came a peculiar ability:[Charm]It wasn't some overpowered skill designed for combat or survival. No, it was something entirely different, yet equally powerful in its own right.[Charm: Increase favorability as more women are captivated by your presence.]This was my key to survival.Through this strange, almost ridiculous skill, I realized that I could change my fate. The powerful female characters, once unreachable in the original storyline, could now be influenced. If I could make them favor me, their strength, influence, and protection would be mine.But it wouldn’t be easy. Each of these women had their own complex personalities, histories, and goals. They were dangerous, capable of crushing me in an instant if I misstepped. But with charm on my side, I might just be able to win them over—and in doing so, alter my destiny.What was once a game of certain death had now become a gamble of life and affection. Every conversation, every interaction, would determine whether I live or die. My charm was my weapon, and it would be the only thing standing between me and the grim fate that awaited Max.Now, with my new plan in motion, I’ll have to navigate the intricate web of relationships and alliances while avoiding the countless threats looming over me. The odds are still stacked against me, but for the first time since I arrived, I can see a glimmer of hope.If I can make the right moves, charm the right people, and avoid the pitfalls, I might just survive this nightmare.Or better yet, thrive.This is my one chance at life in a world of inevitable ruin, and I’ll do whatever it takes to change my story.

…

In the courtyard, beauty at the side, a candle flame wavering.

A gush of clear wind, half a full moon, the peach tree remains unchanging.

…

Wait, whose kid is this?! Why is she calling me papa? Gazing at the little girl in front of him with skin as pale as jade, Chen Xi froze.
