Never Cross the Mundane World

At the foot of Cangwu Mountain, the blacksmith's son opened the door. Mortal spiritual roots are the lowest starting point in the world of immortality. While others can make great strides in a day, he can only reach the same level in ten years. What others are fighting for is the treasures of heaven and earth, but what he is guarding is the fire in his heart. Thousands of years are like a long river, old friends turn into dust, and hometown changes to the human world. He stood on ruins, knelt in front of barren graves, and walked alone on a road so long that there was no end in sight. Later someone asked him what path he cultivated. He said, beat a piece of iron into what it should be.
