The density of Great Monarchs in the "Boundary Curtain" region surpassed that of the "Star Alliance."
Yet, under a theoretically even distribution, each Great Monarch would still be separated by roughly 400 Light-Years—about as sparse as the blue giants scattered across this starfield.
By comparison, when a Great Monarch cast their influence within a radius of two or three Light-Years while focusing on specific fields and levels, constantly observing and analyzing them, the "interfering force" produced by their very existence and the corresponding Rule Environment would inevitably distort the original environment.
Such distortion might not be visually obvious, nowhere near as exaggerated as the analogous "blue giants," but to cultivators who had likewise studied the relevant fields, its presence was far too strong.
Likewise, the "other side's" open attention, observation, and analysis also fell within Tai Yu's perception.
Whether on this side of the "Boundary Curtain" or the other.
The Great Thoroughfare System's search on this side had not ended, and the person in charge was still High Priest Cen Fu.
Great Monarch Xi Hui had come by once in the meantime, and only that once. His level of involvement had clearly declined.
This made Tai Yu's counter-detection easier, but overall, it was not a good sign.
To some extent, it indicated that even a local power like Xi Corporation, which had deep ties of interest with the Great Thoroughfare System, was being gradually excluded from this incident.
While there was certainly the matter of there being no profit to gain, the most important reason was that the Great Thoroughfare System—and even the Myriad Gods Hall as a whole—did not want secular forces deeply involved.
This concerned faith power and the Boundary Curtain. Handling it this way was the most reasonable and prudent choice.
Of course, Xi Hui probably did
