Collect Abilities After Anime

Liu Nan lives in a strange world. Everyone in this world has a talent that seems to be heaven-defying in the eyes of people in other worlds. They all have a "golden left hand". They can grab something randomly in the heavens. It can be good or bad, good or bad, big or small. People in this world are called immortals from outside the world. Because of the randomness of the captured objects, everyone's fate is also full of randomness and uncertainty. Heaven one moment, hell the next.
