The Heavenly Demon once again transformed into a cloud of black smoke to escape. After manifesting his form, he looked terrified.
"What kind of creature are you?"
He turned and flew away, letting out a piercing shriek that echoed throughout the entire Sorrow Cave Heaven.
Yu Ziqing rubbed his forehead and pulled out the rusty sword from his bosom, shouting fiercely.
"Freedom Heaven!"
The shriek of the Heavenly Demon abruptly halted as he stared at Yu Ziqing, puzzled by how Yu Ziqing knew his True Name.
For a Heavenly Demon without a physical body or Divine Soul, the True Name was indeed a vulnerability; however, that depended on the person involved.
For someone like a Ninth Tier Primordial Spirit Realm expert who mastered the Heavenly Devil True Name Spell to the highest level, this was a crack that could kill a Heavenly Demon.
But for others, it was just a name.
