Qin Feng, the surviving son of the Qin family, honed his sword in Canglan Continent. The sword hides the remnant soul of ancient times, Mo Lao, who only talks about swordsmanship but does not take action.
When his peers are fighting, he proves the way with his sword; when a strong man who crosses the hierarchy is killed, his sister Qin Wushuang appears to protect him.
After breaking through the boundary wall with a sword and traveling to the heavens, Qin Feng gave up the constraints of the realm and realized the path of the Heart Sword.
There is no sword in the hand, but there is a sword in the heart. Everything can be a sword. Traveling across the galaxy, the sword returns to its origin.
