Mysterious, low whispers suddenly echoed in Han Yi's mind. The whispers were indistinct, but the eerie power permeating them sought to befog his Divine Soul and confuse his mind.
However, Han Yi's willpower was exceptionally strong, and with the enhancement of the Wan Ming Tome, he had already reached the realm of a high-stage Divine Sovereign. After a moment of daze, he immediately recovered. The whispers around him dissipated suddenly after his recovery, as if they had not truly happened but were mere illusions.
But Han Yi naturally did not think so. His expression grew grave; just upon entering the passageway, such a terrifying encounter had occurred. How dreadful might the happenings at the other end of the passageway, at the Primordial Demon Sect, be?
No wonder the cultivators who entered remained silent and did not return. If it were an ordinary Heavenly Sovereign, without some special means, the eerie whispers just now would have been tough to withstand.
