The upheaval in the Pure Land spread through the circles of Golden Core True Monarchs almost instantly. After all, that cry of "Primordial Heavenly Demon" was essentially directed at them.
As for lower cultivators like Foundation Establishment Daoist Masters, at most they saw strange phenomena manifesting in the direction of West of the River, harboring speculations but unable to grasp the concrete truth.
Moreover, since the Primordial Heavenly Demon had already corroded every Buddhist Cultivator in West of the River, even down to the mortal faithful followers, there was no way to learn the specific details. For a moment, all True Monarchs were on high alert as if facing a formidable enemy.
However, just as all the True Monarchs assumed the Primordial Heavenly Demon would immediately go on a rampage, unleashing a demonic calamity, they saw the latter suddenly smile with ease. Then it vanished. In an instant, all demonic qi seemed as if it had never appeared.
The Arhats, Buddhist Cultivators, Bodhisattvas, and faithful followers who had been exploited by the Heart Demon all returned to normal. The whereabouts of the Primordial Heavenly Demon were unknown. But this did not soothe the worries in the hearts of the True Monarchs; instead, they grew even more tense.
