Lin Mu, a frail young man, wields a cracked iron sword. He has been pretending to be ordinary in the academy for three years, practicing sword moves with no inner strength day after day. Everyone regarded him as a "sick man", but they didn't know that he was pursuing a sword path that no one understood with amazing perseverance - not seeking internal strength, but only cultivating the sword's heart. When the clues left by his father who mysteriously disappeared three years ago reappear, and when the enemy lurking in the darkness reappears, Lin Mu will prove that the real edge of the sword is not on the blade, but in the heart. This is a story about persistence, inheritance and self-proof. Under the belief that "what the sword points to, what the heart desires", the ordinary sword will eventually shine with immortal light.
Purpose: Using the "sword heart" as a metaphor to refer to a person's original intention and belief, it explores how to not rely on external advantages when innate conditions are insufficient or encounter major setbacks, but to seek strength within, and to carve out a path of one's own with pure faith and unremitting persistence. Emphasize that true strength comes from inner direction, not external sharpness.
