The Apocalypse Beggar's Infinite Level-Up System

“Ding! Master, congratulations on leveling up.” He wakes from a nap to find the System already cheering. While everyone else cultivates, he plays around. While they study, he flirts with girls. While they grind monsters to level up, he counts the materials overflowing in his pocket dimension... After transmigrating to a very different world, he wields a god-tier, infinitely upgradeable System. One man and one System are all it takes to slay every kind of demon and monster! In this chaotic world, who will rise to the top?
