Nine Heavens Sword Emperor

"The sword is the king of all weapons, and the sword art is also ever-changing.
The sword can be elegant and agile, and cleverly resolve the situation;
It can also be heavy and fierce, and use force to split mountains and break seas;
It can also be thunderous and powerful, and use speed to break all laws in the world."
A beautiful sword god said so, and the boy took the sword in her hand, but he didn't know whether this sword could resolve the current situation of rampant monsters and chaos in the world. . .
