Hearing what Lu Qiu said, Zhu Lin was slightly surprised and asked, "There are humans who can detect your demonic energy?"
Lu Qiu thought for a while and said, "It's not that the man was able to detect my demonic energy, but it was the strange thing he was wearing that could detect my demonic energy."
"Can you explain the shape of that thing?" Xiu Wu asked.
After thinking about it, Lu Qiu took paper and ink and started drawing. A few minutes later, he showed the painting to Xiu Wu and Zhu Lin and said, "This is what he was wearing then. I remember that that thing made a strange sound when that person walked past me."
Xiu Wu looked at the painting and said, "This is a detector. Ordinary detectors are used to detect bombs and underground mines. As for the detector that can detect your demonic energy should have been specially modified for that purpose."
