Blue Demon continued, "The path of disguise techniques is a very special one. Each of us can only make our disguises more deceptive, but we cannot see through the disguises of others. For example, I can't guarantee to see through you, nor can you guarantee to see through me. Likewise, both you and I can't guarantee to see through him!"
"Understood! Even if we know he's hiding somewhere in the Southern Border, we simply cannot find his true identity. That's the biggest challenge of this mission!" Lin Xiaosu nodded.
"It is a challenge, but not the biggest one!" Blue Demon said.
"What's the biggest challenge then?"
"Witchcraft!" Blue Demon said, "As I've mentioned earlier, in the tragic case of the Dong Family's annihilation, there were signs of witchcraft. Yet, even Qianlong has only grasped the tip of the iceberg regarding the mystery and power of witchcraft."
There's a kind of terror in this world called "the unknown"!
