"Ye Yuan! Even a Sea Transformation Realm lost his life after entering! Do you want our elders to seek their own doom?"
Ling Potian rarely said so many words. It was just that he was very stern currently. The average disciple would probably start stammering when they saw it.
"Potian, let Ye Yuan finish talking," Luo Qingfeng said.
Ling Potian was stunned. He immediately shut his mouth and kept quiet.
Ye Yuan did not mind either. He continued, "If my conjectures are correct, it might be because the space isn't stable or due to restrictions on laws. Sea Transformation Realm and above martial artists are unable to enter this mystic realm. It's overly dangerous for Crystal Formation Realm martial artists to enter; that's why the Heavenly Sky Sect would join hands with the other seven sects to explore together in an unprecedented event."
