With this in mind, he looked at Shangguan Xiyue and said, "This might hurt a little. You'll have to bear with it."
Shangguan Xiyue's expression tensed, and she clenched her small fists. "Okay."
Wang Xiao then activated the Inner World within his brow, causing it to rumble and shake.
Then, the Inner World flew out from his brow, sank into Shangguan Xiyue's, and enveloped her Mud Ball Palace.
An Inner World is formed from the evolution of the Mud Ball Palace; it can be thought of as a fertile field for growing crops.
Wang Xiao was temporarily lending his fertile field to Shangguan Xiyue.
This way, Shangguan Xiyue could also borrow Wang Xiao's Inner World to temporarily sense the Heaven and Earth Spiritual Qi!
Since a Spirit Root exists to absorb Heaven and Earth Spiritual Qi, then when stimulated by Spiritual Qi, even a Hidden Spirit Root should react!
