The Fourth Age of Seeking Immortality

My name is Gu Shaoyu, and I grew up in an ordinary village. The village chief said: "The outside world is wonderful, you should go out and see it." Me: "Okay." So, as a passer-by, I embarked on the road to becoming an immortal. (Gu Shaoyu is the protagonist, but he will not focus on the description. He is just the experiencer of each event. He is not invincible, has no artifact, and does not pick up girls. However, there are still plug-ins, hehe)
