The world is like a tide, and people are like water. There are countless people in this world, and the unspeakable things are like the tide by the river, wave after wave, which will never stop. There are a few people. It's like the waves, always so eye-catching, they will go to places that ordinary people can't reach, and see the scenery that ordinary people can't see; If you have to catch some more people out of this small group of people, it's not nothing, it's just rare. Just like a tidal wave by the river, they are the tide and the tide makers... Since he was a child, he has listened to his grandfather tell these stories and heard about the man-eating monsters on the mountain. The charm of the mountains. The pride of the mountain... The young man didn't realize any big truth, he just felt that life was like chopping wood. It doesn't matter how big or small. An axe can be solved with a single down, as long as you can hold that axe, that "axe" that can decide the life and death of others. Finally, one day, the boy picked up an axe and stepped into the "big world" that he had been yearning for.
