With the aura of a stay-at-home dad, he is nothing but a middle-aged man who adopts a group of lolis... and an army of freeloading aliens that came out of nowhere. Er, what? Ahem. Really though, this is a super-serious story... a super-mega-ultra-serious sci-fi story. For the Empire!

His hybrid vein held the promise of limitless strength, yet it shackled him in the first stage of evolution, a prisoner of his own potential. Then the asteroid exploded. It shattered his fate. Now, Ash wields the Titan Vein, a power that bends the laws of his fractured world—a planet split between humanity and horrors, divided by an impenetrable fog. But his newfound strength carries a soul-rending cost: he is no longer alone in his mind. An ancient entity, one step from godhood, stirs within him. And it’s starving. With his crew, Ash plunges into the unknown—across the planet’s cursed half, through time-warped ruins, and into the cosmic void where the gods vanished. Each revelation twists him further from human. Each power-up pulls him closer to oblivion. The more he ascends… the less of him remains.

Divorçons. Je transférerai la propriété que je t'ai promise à ton nom. » Mo Rao dit, « Ne pourrions-nous pas divorcer ? Et si... je suis enceinte... ? » Fu Ying répondit sans cœur, « Avorte-le ! Je ne veux plus d'obstacles entre Qu Ru et moi. De plus, Qu Ru a la leucémie, et ton moelle osseuse est compatible avec la sienne. Si tu es disposée à faire un don, je peux te promettre n'importe quoi. » Mo Rao dit, « Et si ma condition est que nous ne divorcions pas ? » Les yeux de Fu Ying se durcirent. « Mo Rao, ne sois pas trop gourmande. Même si je te promets quelque chose pour Qu Ru, tu sais très bien que je ne t'aime pas. » Les mots « je ne t'aime pas » poignardèrent le cœur de Mo Rao comme un couteau. Son sourire devint soudainement tordu et elle n'était plus la femme docile qu'elle avait été. « Fu Ying, c'est la première fois que tu me répulses autant. Tu me traites de cupide, mais n'es-tu pas pareil ? Tu veux que je divorce pour que tu puisses être avec Qu Ru ? D'accord, j'accepte. Mais tu rêves même que je la sauve ? N'oublie pas, on ne peut pas tout avoir dans la vie, comme toi et moi. » Puis Mo Rao s'en alla. Fu Ying se sentit réellement suffoquer, et ce sentiment le rendit fou. Lorsque Mo Rao réapparut, elle était devenue une étoile éblouissante. Quand elle se présenta devant Fu Ying, tenant la main de son nouveau beau, Fu Ying se moqua éperdument et dit, « Chérie, n'avais-tu pas dit que tu m'aimerais seulement ? » Mo Rao sourit légèrement. « Désolée, ex-mari. Je m'étais trompée à l'époque. Tu n'étais qu'un remplaçant. En fait, j'aime quelqu'un d'autre. »

Humans escaped Earth's prison and conquered the Solar System. Peace has reigned for a thousand years. Yet, the Terrans became mired in their comforts and decadence, neglecting the other inhabitants of the Solar System. So begins a new age of war, a tragedy of a long neglected history. Author's note: In this story, I intend to integrate elements from shows I love-- gundam, modern sci-fi shows such as 'The Expanse', add strategic elements from shows such as legend of galactic heroes. These elements might be political intrigue, more technological development, robotics, cyberpunk, character development, rationality. Ultimately, I want the story to end up with a strong sense of hope despite the horrors of conflict.
