A Man's Journey to the Mountains and Seas

In ancient times, gods ruled the world, hundreds of tribes lived together with humans, strange beasts multiplied in the wilderness, and the strong flew across the mountains and seas. Years have changed, time has passed, and the sea has changed. When humans return to that time and space, will they still be able to dominate all things, dominate the ups and downs, control their destiny, and reproduce the future? I have a sword that can open mountains, split the ground, and divide the sea... I have a punch that can destroy cities, shatter the sky, open the sky...
