What Do You Mean My Entire Career Depends on Drawing Cards and Trying My Luck?

One day, when Fang Xiang opened his eyes, he discovered that a System called Nightmare had taken him to various dream dungeons and was forcing him to complete some damn System missions. But why was he just an ordinary person? Fortunately, the System was fairly considerate and even gave him a thoughtful career-draw feature. As he made progress on System missions, he could earn more draws. But careers came in all shapes and tiers: 3: Common career 6: Special career 9: Exclusive career At first, Fang Xiang didn't think much of it. But after drawing a 3 several times in a row, he began to realize something was wrong. I'm Chovy, give me something good with these draws! There's no pity system, so what does it mean to keep giving me mediocre careers? Then Fang Xiang finally drew a gold. Wait, what the hell is a [Musician]? [Chant] What kind of useless skill is this? Effect: By chanting, you can apply various buffs or debuffs to anyone within five miles who can hear you. The effects depend on the piece you chant. Also, when you begin chanting, you enter bullet time and briefly become untargetable. Holy crap, it even gives me invincibility frames. That's amazing. After clearing every dream dungeon, Fang Xiang became [Morpheus]. Looking at the System panel before him, he saw: [Hero] + [Demigod] + [True Immortal]... He was stunned. "You never told me these careers could stack endlessly!"
