He was originally just a hard-working man at his work station. In an accident, he was killed by a crystal chandelier. He time-traveled into a child with the same name. He discovered that the place the child was in was not a kind place. He ran away to other places and discovered that this turned out to be the world of Journey to the West. Since he was in Journey to the West and the system was added to it, if he didn't cultivate immortality, wouldn't he be sorry for God's gift?
