Kill Your Target: The Assassin's Creed of the Myriad Worlds!

[Infinite-flow + no System + no heroine + not brainless + not a saint + tabletop RPG instances + decisive and ruthless + slaughtering everything in sight] Shocking! Every living being across parallel spaces, multiverses, infinite worlds, and all dimensions was collectively stunned! "One man stands above the ages, tramples the Land of Light, punches Cthulhu, and stomps on containment objects. This guy is terrifying!" "Have you seen the title over his head? It looks like it's about to break through the heavens!" "With talent and style like that, he's truly in a league of his own!" All the living beings watched Lin Yan slaughter anyone who stood in his way on the livestream, their faces filled with shock. Lin Yan is an amnesiac assassin. When he wakes up, he finds himself aboard a strange train, which takes him into a higher-dimensional space. This is how he unlocks a game leading to the Myriad Worlds. From the Four Great Classical Novels to the Twilight of the Gods, from fragile flesh to the rise of machines, whether it's spiritual qi revival, xianxia fantasy, game worlds, or film and television, anime, and variety shows... He can earn an equivalent lifespan by changing the plots of worlds across the heavens, or killing famous characters and creatures. He can use this lifespan to buy anything from the worlds of the heavens, across infinite dimensions and parallel worlds.
