Kapitel 730: Supreme Heart Demon Chant

"Found it?"

Hearing Mu Chen's words, a surprised look burst out from Nine Nether's charming eyes, and then she felt some disbelief. After all, the Thunder Magic Sect had not managed to find the item for so many years, but Mu Chen had only taken four days to detect the fluctuation from the Netherworld Thunder Heart.

"Should be it." Mu Chen nodded in excitement. He lowered his head to look at his palm and said with a solemn look, "But the Netherworld Thunder Heart is really overbearing. Just its sound caused me to lose myself."

"The Netherworld Thunder Heart is a very weird lightning among the many types of lightning in the world. Its power is not fierce and violent like the other types of lightning. Furthermore, it does not attack through actual lightning but rather through a lightning roar," Nine Nether explained.

"Lightning roar?" Mu Chen squinted slightly.
