Fang Bai was in great pain, while Yanshi Immortal Emperor was very shocked.
His previous sound wave attack was merely a test of Fang Bai's strength.
Although he noticed that Fang Bai possessed the Innate Fire Spirit Root, he wasn't certain about Fang Bai's combat power and wanted to see if the title "Wushuang Immortal King" was self-proclaimed or if there was true skill behind it.
The sound wave attack he used was something even a seventh-ranked Immortal King Realm expert couldn't withstand and would suffer some injuries. Yet, unexpectedly, Fang Bai remained unharmed.
Thus, Yanshi Immortal Emperor could confirm that the combat power of this Wushuang Immortal King surpassed most immortals of the same realm in the Immortal Realm and was outstanding even among the prodigies of the Golden Crow Palace.
"Hmm, not bad... quite interesting..."
Yanshi Immortal Emperor stroked his beard and looked at Fang Bai with an expression of admiration.
