The Thunder Temple's highest alert spread without a sound. Invisible detection waves radiated from the Sanctuary like the most sophisticated radar, sweeping again and again through the vast reaches of space from Earth-Moon orbit to the edge of the Oort Cloud. Remy mobilized almost all the Sanctuary's computing power, combining it with some of the dimensional surveillance data provided by Kamar-Taj in an attempt to catch even the slightest anomaly.
Yet, just as Remy had warned, the farther the distance, the lower the scanning resolution. The vast expanse of the Oort Cloud, filled with frozen celestial bodies, comets, and cosmic dust, served as natural camouflage, perfectly concealing the uninvited visitors' traces.
Lin Ye stood before the console, his brow slightly furrowed. The brief tremor in the [Origin Thunder Seal] on the back of his hand and the faint sensation of being watched had vanished, as though they had merely been illusions. But he trusted his instincts, especially the almost instinctive forewarning of danger that came from his deep attunement to the thunder law.
"No anomalous energy or spatial fluctuations," Remy reported. "No energy residue consistent with an 'interstellar jump' has been found in the outer Solar System. Extensive background radiation interference exists in the Kuiper Belt and Oort Cloud regions. The possibility of exceptionally advanced cloaking technology cannot be entirely ruled out."
"Raise the internal defense level. Set every detector and energy sensor to maximum sensitivity," Lin Ye ordered. The enemy clearly possessed highly advanced stealth technology. Passive scans would struggle to find them; he could only wait for them to approach or expose a weakness.
After a moment's consideration, he opened an encrypted communications channel to Kamar-Taj. The Ancient One's projection soon appeared.
"Lin Ye, what is it?" The Ancient One seemed to be meditating, her presence calm.
