"Active attack on immortal energy?" Xu Hei frowned, "What kind of setup is this?"

An elderly Immortal Monarch with white hair said, "I was only inside for the time it takes a stick of incense to burn, and I was attacked five times, nearly losing my life. Yet my disciple came out unscathed and is still inside."

"Are concealment methods effective?" Zhang Wei asked.

"Not very," Qinghe Immortal Lord replied. "We used the Dustless Immortal Talisman, the Divine Concealment Talisman, and the Boundary Stabilizer, which only reduced the likelihood of being attacked but couldn't completely avoid it. Once any mechanism detects you, all the mechanisms will attack simultaneously, rendering previous concealment useless and putting you in a dire situation."
