Back before Leng San and Qinglong De’s battle was ended...
The shadow of the huge Dark Formation in the sky covered the entire territory of Qinglong Palace, resulting in Qinglong Xuanyuan's freedom of movement with his Shadow King’s Dimension technique.
Initially, Qinglong Xuanyuan hid in the shadows of his men or those of the enemy to move quietly within the shadows. He even hid in the shadow of palaces and buildings sometimes, but that was no longer necessary.
Since the entire battlefield was covered with shadow, it allowed Qinglong Xuanyuan to reach everyone by evading any kind of detection!!
The short knife in Qinglong Xuanyuan's hand was an Emperor-Class runic weapon named the Night Fang. The weapon did not have any special abilities at all, other than its sharpness. With its Emperor-Class runic pattern, it could slice a piece of metal as if it were a tofu.
