Transformed into a Great Swordsman

I have been begging for ten years in a remote village, with no clothes to cover my body, no food to eat, and I have to drag my underage sister with me. He suffered all the cold looks and humiliation, and tasted all the dangers in the world. A miserable start, a desperate start. Until God opens his eyes and lets a smelly old man lead me up the mountain, and I transform into a genius, an unparalleled swordsman. Let's see how I can change my destiny against the will of heaven and embark on the endless path of cultivating immortality!
