Normally, a Ninth Rank existence breaking through to the Tenth Rank wouldn't cause such a disturbance.
It merely attracts the infusion of the Cosmic Origin Source from a million miles around. Not to mention those at the Eleventh Rank, even a Supreme Being would hardly notice.
Breaking through from Tenth Rank to Eleventh Rank? If it still triggers an infusion of the Cosmic Origin Source, the amount of disturbance it causes is still insignificant.
Choosing a deserted Star Domain to break through, one could pass through completely unnoticed.
And a Tenth Rank understanding the Rule of Time breaking through to Eleventh Rank? Since the beginning of this Cosmic Era, such occurrences can be counted on one hand; such Tenth Rank beings will seek the protection of a Supreme Being before breaking through.
Just like how Xia Qin Supreme Being and the Feather Butterfly Supreme Being set up a spacetime barrier for Lin Yuan's breakthrough.
