"Of course, it can only be used once," she said sympathetically to the old man, "If I'm not mistaken, the moment you press that mechanism, no one in this study will survive, including yourself. If the person who set it up was even more ruthless, it might even blow up the entire Wu Mansion. Heh, isn't it only meant for one-time use?"
Mr. Wu was shocked, as if he had thought of something, his face turned pale, but he stubbornly said: "How could it be?"

She sneered, "If a Cultivator sneaks in here, your life might be a minor matter, but the intelligence in your hands must not be leaked, especially not to Fengtian Prefecture about the activities of Fire Worship Valley. If this study room is threatened, blowing it up with a thunder would perfectly destroy any evidence or clues."
"Why don't you go press that mechanism and see?"
