Doomsday Roulette: From the Start, I Can Choose the Sequence Potion

[Roulette apocalypse + strange horrors descend + lifespan and crystal core draws + ruthless protagonist] A strange cataclysm descends, and endless monsters sweep across the land as civilization from the old era collapses. Along with the monsters, fate's roulette wheels appear all over the world. There are only two ways for people to gain extraordinary powers: sacrifice their own lifespan, or hunt monsters, dig crystal cores out of their heads, and put them into a roulette wheel to draw a reward. The roulette rewards include everything under the sun: sequence potions, extraordinary professions, strange artifacts, and rare supplies. But every draw depends entirely on luck. Some people spend ten years of their lives just to get a pack of instant noodles. Others fight monsters to the death only to draw worthless junk. Everyone is gambling with their lives, betting on that faint hope of gaining extraordinary power. Xiao Yu, however, awakens a unique ability: Designate the Result. He can not only lock in his target when drawing from the roulette, but choose the outcome of any random event. While everyone else gambles with their lives and leaves it to luck, Xiao Yu can get whatever he wants. But the gifts of fate always conceal a price. Monsters surround them, people are impossible to read, and a deeper secret behind the roulette wheels lies at the heart of the cataclysm. While everyone struggles desperately to survive the apocalypse, Xiao Yu wields the power to choose the outcome of anything random and carves out his own path to transcendence amid the ruins.
