This book is a fan fiction of *The Cycle of Reincarnation*. Roland, a professional gamer invited to participate in a live stream test of the new version of *The Cycle of Reincarnation*, unexpectedly finds himself transported to the game world. Unaware of this, Roland believes he's still in the game, marveling at the significantly enhanced realism and immersion of the new version's content. He then uses the most sophisticated and challenging techniques to conquer the Cycle of Reincarnation and complete speedrun challenges. Wheelchair-level skill configurations and builds, textbook-perfect dungeon strategies, in-depth exploration of hidden resources and side quests, coupled with a ton of effort and a bit of luck—all these factors combine to create a "monster" who rises rapidly in the Cycle of Reincarnation! "A realm beyond the Grandmaster of Swordsmanship? What a joke! How could such an existence exist?!" "Freezing time and space, plunging the abyss and elements into a stagnant ice! How terrifying!!" "Damn it! That's not his cloak! That's...that's...tens of millions of vengeful spirits!" Facing the terrified beings of the Astral Realm, Roland remained indifferent, only keeping his arm around Bai Ye's shoulder, loudly plotting, "Lao Su! I'm planning to stand up and run for the director of this Paradise of Reincarnation, do you support me, brother?"

To end the curse that had plagued his family for millennia, he chose the darkest path.

As the 97th Master of the Demon Slayer Corps, Kagaya Ubuyashiki has always been a gentle and revered leader in the hearts of all his members. However, as the curse increasingly erodes his life, and as he foresees that his daughters will repeat the same mistakes, on the verge of despair, he makes a choice that will shake the world—to make a deal with Muzan Kibutsuji and become the most hidden Upper Moon Zero.

By day, he remains the lord who guides everyone in the fight against demons; by night, however, he is loyal to his millennia-old nemesis. When the truth is revealed on the eve of the final battle, the Demon Slayer Corps' faith crumbles overnight. The former "father" becomes the most despicable traitor, and the Pillars who once swore their undying loyalty turn their blades against each other.

But at the end of this sin-soaked road, does Kagaya hold a trump card that can turn the tide for a thousand years? When wisteria blossoms alongside bloodshed, this game of chess that began with betrayal will finally reach a shocking conclusion.
