After numerous attempts, Dong Tianyu had already confirmed that even though his body could leave the body of the ship for a short while, as time elapsed, he would gradually feel weak, and he needed to have a limb in contact with the ship's body to relieve this weakness.
Having confirmed this, Dong Tianyu began to observe his surroundings, wanting to know how he could obtain the Mysterious Core within the Mysterious Realm.
However, at this moment there was nothing around him, just himself, alone with his ship, in the midst of the vast ocean. Even with Dong Tianyu using his Divine Sense to carefully observe his surroundings, there was never any other discovery from the beginning to the end.
Dong Tianyu looked up at the sky, where there was neither sun nor stars. The azure sky was devoid of even a single cloud.
