I Draw Cards in a Jiangshi World, and Get Uncle Nine from the Start

Lu Ming transmigrates. The good news: he has a System. The bad news: the System determines that this world is in the apocalypse, and he is a completely useless nobody with zero combat power. His only way to survive is to draw cards and summon allies. For his beginner draw, he prays like crazy that he won't get some random nobody. A golden light bursts forth: an SSR, Lin Jiu, heir to Maoshan. Uncle Jiu?! “You call that a zombie? That’s a jiangshi.” “Yes, yes, you’re right, Uncle Jiu, but the one behind us looks like it’s sprinting a hundred meters!” From then on, Lu Ming lives by relying on Uncle Jiu. He fights jiangshi, earns points, trades them for magical artifacts, and unlocks the Maoshan patriarch. His sharp tongue gets him into trouble, and Uncle Jiu cleans up after him. He recklessly courts death, and Uncle Jiu bails him out. Uncle Jiu: What on earth did I do to deserve this?!
