The pool was only about an acre in size, not large, yet the chill leaking from it seemed capable of freezing one's blood vessels into knots, leaving one's blood and qi unable to circulate properly.
Both of them possessed combat strength at the Peak Heavenly Immortal Realm. Yet when faced with this cold, even they found their immortal power running sluggishly. Its terror was evident.
The cold alone would have been one thing, but sparks of lightning occasionally surged through the pool, as though every drop of liquid were formed from lightning. It was at least dozens of times more powerful than the Myriad Tide Thunder Sea Nie Yun had entered with Tantai Lingyue.
