Morning Dew Sword

Shen Wenlong held the knife across his chest. The knife remained motionless, but there was a faint trace of the knife that kept flashing with the light. There was a light blue mark near the handle of the knife, which was shaped like a drop of dew or a drop of a lover's tears. Whenever this sword is full of human blood, this dewdrop will stand out, and its color will change from light blue to bright red, dazzling and crystal clear.
