The multiple concealment techniques set up by Jiang Qiue are actually very strong.
Neither Leng Xiu nor Burning City detected the existence of the underground safehouse, and even the most mysterious Light Disciple passed through this domain without discovering them at all.
But sadly.
When the number of enemies grows large enough, and their techniques numerous enough, there will always be abilities that can counter Jiang Qiue's concealment techniques.
For instance, this massive shadow spreading rapidly over the snowy land, with threads of black lines surging within the shadow, like a tide of insects passing through, yet silent.
The instant the safehouse was enveloped by these shadows, the distant Ji Ying halted its form, clearly indicating this shadow as a very powerful surveillance technique.
The Light Disciples advance in the sky, and Ji Ying glides on the surface, one light and one dark, passing by everywhere, probably leaving no one able to escape their probing capabilities.
