The Walker's Hidden Secret 20th level made Xue Ying's Void Evasive Maneuver extremely formidable. He was able to move stealthily to the side of the enemy. Adding the Mirage World's concealment, Xue Ying's movement became undetectable by even the 'Hundred Leading Howls'.
A silver spear abruptly appeared from the void, going straight towards one of the eyes on one of the Hundred Leading Howls hundred heads. The spear moved like a faint shadow - indescribably fast and sudden! But the 'Hundred Leading Howls' was within the Void God realm and reacted instinctively. For all its speed, the spear missed its intended target, the eye, and struck the cheek of that head instead.
The skin of the creature was extremely firm and was covered in thin veined patterns. When Xue Ying struck it, it felt as if he was striking the void. Chaotic energy worked to guide the spear away.
