Flying above the sea, Roy allowed the demons to search while he adapted to his Radiation Perception ability.
This ability was very powerful, but the premise was that Roy had to master precise control of this perception.
Any object, as long as it did not reach absolute zero, would emit heat radiation. This was the physical property given by the energy of an object and could never be eliminated. In other words, from now on, any invisibility effects would be useless in front of Roy. Even if the other party could control their aura and magic power to deceive the five senses, it was impossible for them not to emit radiation, and Roy's Radiation Perception would detect them.
This ability was absolutely unique for finding people and objects. As long as Roy could proficiently discern the different radiation wavelengths of each object, even if he did not see it clearly, he could still determine the location of the object by the radiation wavelength it emitted.
