The spiritual qi river in the meridians of an Ocean Gathering Realm expert will surge like the sea.
However, a Divine Thought Realm expert doesn't increase the speed of the spiritual qi river; instead, upon crossing from the Ocean Gathering Realm to the Divine Thought Realm, cultivators can generate divine thoughts, another term for which is divine sense.
Divine thoughts are a very elusive mental power. Experts of the Divine Thought Realm can use divine thoughts to investigate the surroundings broadly and detect even subtle changes. Of course, there are also combat skills related to divine thoughts. This kind of mental attack can catch the enemy off guard. However, combat skills related to divine thoughts have always been very rare. Even in many major sects within the Earth Profound Realm, such skills are absent.
Nevertheless, to possess divine thoughts, one must open the sea of consciousness in the brow. This sea of consciousness is the source of divine thoughts.
