I've got a system by a dumb luck

#WPC148
Thomas and three other people appeared in the world of cultivation.
While Thomas still thinks that he's dreaming, the other three of them are searching for answers, leaving him alone. He finds a golden coin activating "Dumb Luck system." That's how his journey starts. Will he cultivate his luck, follow this random road, and use it to become a legend, or will he choose to practice like others, and steadily try to reach the peak? And when will he finally understand that his dream ended, he died and reincarnated?!
