Lin Yi recognized it at a glance; this was, in all likelihood, the Mad Fiend Immovable Seal.
Taking into account what the old celestial being had said, the location of the Mad Fiend Immovable Seal was not fixed, which explained why they had been unable to track it down for so many years. Especially given Lin Yi's current mental strength—at full exertion, his psychic power could blanket small nations—it stood to reason that few things could escape his detection. If one considered this a mirage, however, many things began to make sense.
In human scientific research, the phenomenon of the mirage seemed to have been thoroughly demystified. It was understood as complex changes in light refraction in deserts or over oceans, causing real objects to be imaged in distant places. This was indeed true, and researchers had documented such cases. Yet, what many failed to notice was that the number of cases where the original source of the image had been found was negligible—less than 10 percent. In the modern age of advanced networking, this was inherently abnormal. It was even more anomalous when mirages displayed ancient architecture or scenes that clearly did not belong to the current era. Most importantly, mirages only ever contained buildings; no one had ever seen a person projected in a mirage, which was equally baffling.
