Eight years ago, martial arts genius brother Lin Qingshan "falled off a cliff" to save her after his meridians were shattered and he was stigmatized. He left a last-minute letter and died. Eight years later, Jiang Lin is already the iron-blooded coach of the national martial arts team, leading the team to compete in top international competitions, but encounters malicious humiliation and unfair competition from Western fighters. In a desperate situation, the man who was said to be dead returned coldly as his opponent's "ultimate weapon". On the field, he was her most familiar enemy; off the field, the web woven by eight years of forbearance and misunderstanding suddenly tightened. When the light of the sword in their left hands cuts through their prejudices, they fight for their lost youth and dusty martial arts. After the cold winter, on the green mountains, can they still find the moon they lost to each other?
