In ancient times, evil dragons were infested and all life was in ruins. One day, a young man walked out of the mountains. He was carrying a sword on his back. With this sword, he could kill countless dragons. The people called the young man a hero and called him "Long Yijie".
One day, when the young man was slaying a dragon on a cliff, the evil dragon became furious and swept the young man into the abyss with its long tail. The young man thought he was certain to die, but unexpectedly he fell into an adventure that seemed more like a dream than a dream...
Purpose: The boy who slays dragons will one day have no dragons to slay
