Lu Wei's gaze shifted slightly as he sat up straight. "You mean, it might come from an unknown world?"
Ke Lu nodded. "This beast is enormous, swift as lightning, and its astonishing explosive power exceeds the physiological limits of normal creatures. Moreover, it appears and disappears without a trace, evading even infrared surveillance cameras. That's why I deduce it must be from another realm."
Lu Wei frowned, rewinding the footage to carefully review the segment where the beast appeared. Indeed, it seemed to materialize out of thin air, coming and going without a trace. And when it finished off the men in black and stood between him and Qiqi, its behavior was peculiar—it extended its left front paw toward Qiqi, moving slowly and tentatively, a stark contrast to its ferocious, violent attacks on the men in black. Those men were all killed in one blow at a speed nearly imperceptible to the human eye, yet its movement toward Qiqi seemed utterly non-aggressive. If one looked closely, it didn't appear to be an act of harm but rather a gentle attempt to... caress?
As Lu Wei reviewed the footage, he recalled the scene—at that critical moment, Qiqi stood beside him, tremblingly uttering a name.
Though her voice was low, he heard it clearly.
Rong—Yi—
She called out Rong Yi.
Lu Wei then remembered the first time he saw Rong Yi—
A team of police officers, treating him like a serious criminal, escorted a stunningly handsome man with long, disheveled hair into the hospital. At the time, Rong Yi was in a deep coma. Yet, when Lu Wei examined and bandaged his wounds, Rong Yi suddenly regained consciousness—he had eyes like a wolf's, so dark, cold, sharp, and dangerous, filled with bloodthirsty savagery and an almost scorching madness... If Lu Wei hadn't quickly administered a sedative, he might have erupted in fury right then.
Moreover, Rong Yi had a wound on his waist from a sharp object, quite obvious when he was first brought in. But by the day he was discharged, the injury had nearly completely healed.
Such rapid healing wasn't something an ordinary person could achieve, was it?
"If it's a creature from another realm, Mr. Ke, can you find a way to track it?" Lu Wei asked.
Detective Ke Lu pondered for a moment, then packed away the series of precision instruments spread out in the study. He opened a high-end dark brown leather case he carried and pulled out an exquisite gold-plated pocket watch.
"This is..."
"This is a Yin-Yang Compass, capable of sensing supernatural beings."
Ke Lu clicked open the watch's clasp and showed it to Lu Wei—the exterior was shaped like a pocket watch, but inside, it featured a black-and-white Taiji diagram. The markings that usually indicated minutes were replaced by strange symbols, evenly divided into six parts. A single needle on the dial trembled slightly after the watch was opened, then calmly pointed to the first segment.
"The universe is divided into six realms, each with its own magnetic field. If that beast truly comes from another realm rather than the human world, it must have a unique frequency. Holding this Yin-Yang Compass near it will cause the magnetic field to shift, the needle to tremble, and point to the realm it belongs to."
Detective Ke spoke with ease, shedding his sharp, rational detective persona and adopting the air of a reclusive mystic.
Lu Wei pointed to the circle of markings on the watch and asked, "Six realms? Do these six segments correspond to the six realms you mentioned?"
