Difficulties at the End of the World, Counterattack and Slaying the Sky

Man, his strength can shake the mountains but his body will not fade! People who live for hundreds of years are immortal! Human beings and souls are still immortal after thousands of calamities! The power of ancient humans is unimaginable, and it is precisely because of their power that we now deny that period of history. "How can a person be so powerful?" This is what most people think. People thousands of years ago could believe that objects weighing dozens of tons could carry people soaring through the sky. They believe that people can talk to each other even though they are thousands of miles apart. They believe that a small cannonball can destroy a city thousands of miles away. All doubts come from our ignorance and weakness. But if all that is true, then what is the reason that caused people to change from being extremely powerful in the past to being so weak now.
