After learning of Shen Ningbing's whereabouts, Li Qing did not rush to leave the Yin-Yang Sect.
The Ice Spirit Clan was the sixth-ranked powerful race on the Tianyuan Continent. No matter how anxious he was, he could not simply storm into the Ice Spirit Clan's territory and demand someone, as he had done with the Yin-Yang Sect.
Though this race had a sparse population that had always remained at around a million, far fewer than the human race, every one of them was extraordinarily powerful. Even the weakest Ice Spirit Clan member possessed Nascent Soul Realm strength.
Their clan had a total of five Mahayana Realm ancestors. Several had lived for an incredibly long time and were natural darlings of the ice Dao laws.
Li Qing's current strength was not weak, but if he wanted to demand someone from the Ice Spirit Clan, it was still far from enough. At the very least, he had to truly advance into the Mahayana Realm before he would have the qualifications to negotiate with them.
As for why Shen Ningbing had been taken away by some Ice Spirit Clan powerhouse, the Yin-Yang Sect Master did not know either. It presumably was not because of her ice spiritual root.
Although Special Spiritual Roots were rare, within the human territories of the Tianyuan Continent, cultivators with such aptitude were born every hundred years or so.
Li Qing guessed that it should be related to the cultivation technique Shen Ningbing practiced.
He still clearly remembered that Shen Ningbing's cultivation technique contained a forbidden scripture. After the spiritual power within her body was exhausted and dried up, it could transform her flesh-and-blood body into an ice crystal body in exchange for spiritual power.
Back then, Shen Ningbing's master, Ancestor Bingyun, had used that forbidden scripture many times.
