Mountain and Sea Sword Master

The world of mountains and seas is all-encompassing. Outside the world wall, in the far north, there are millions of magical beasts; there are six spiritual beings, each with their own mysteries, including fists, feet, weapons, and magical powers; I, Yi Wuyun, only have one sword—— "Wait a minute, isn't this introduction wrong?" Yi Wuyun asked doubtfully, "Do it again!" I, Yi Wuyun, just want to farm quietly, make some money, live a peaceful life, and by the way... Become the best in the world, that's all.
