Xia Pingan was completely held hostage by the old man and couldn't move.
The old man looked like he was flying at the bottom of the sea. His speed was unbelievably fast and he was flying towards the depths of the undying sea, which made Xia Pingan's heart beat faster. There were so many more monsters in the undying sea than on land. If one was not strong enough, they would die without even knowing how they died if they ventured deep into the undying sea.
Most of the summoners who came to the undying sea were only active near the shallow waters of the islands. Only the summoners above the ethereal opening realm would gradually try to go deep into the undying sea.
