The "female thief" in the night suit looked around vigilantly for a while, then lowered her head and bent her waist before burrowing into the dark hole.
"Hu!"
In the darkness, she let out a light breath. Sparks flew and a cluster of flames burned quietly.
The match emitted an orange glow that dispelled the surrounding darkness. She raised the match and looked at the cave wall. The traces of man-made excavation were very obvious.
The black-clothed woman's free hand reached to her waist, where a short blade was attached.
The short blade was slowly unsheathed without making any sound. The fiery glow illuminated the blade, making it appear pitch-black and devouring the light.
This weapon was called ink tooth. It was made of black iron and the fangs of ink scale beasts. It took a month to make and was one of the most proud works of Song Qing, the Directorate of astronomy.
