Capítulo 209: Chapter 210: A Duel of Techniques? No, a Heroic Song

Reminded by Miao Yin, although everyone's hearts were in their throats, they still followed the advice.

They used True Yuan to protect their bodies and shut down their five senses.

Given the current circumstances, there was no other option; with the Demon King Hong Li's powerful divine ability, even an onslaught from those Below the Harmonization Realm could be hard-pressed to defeat her.

They might as well listen to Miao Yin; maybe she had a plan.

Although Miao Yin had been swept by the current too, she kept gathering her energy. By now, she had accumulated her full amount of mana.

"Heavenly Sound: Thunder!"

Perfected Miao Yin formed a spell seal and emitted a thunder sound from her Dantian.

Boom!

The sound was so realistic, as if real thunder had exploded, causing the demon kings to shudder.

Thunder itself had the imposing prowess of a demon-slaying exorcist, and hence demons were most afraid of thunder. Just the sound was enough to scare the water demon considerably.
