Spirit Sea Realm powerhouses can walk on air without the assistance of magic artifacts. The reason is that after opening the Spirit Sea, their Dantian can contain significantly more Mana True Yuan. This makes their Dao Body more ethereal, almost like nature's spiritual energy. Expending only a bit of Mana, they can soar through the sky and burrow into the earth without hindrance!
Allow me to present a somewhat imperfect analogy. A Qi Gathering Realm cultivator is like a solid iron ball; if thrown into water without external force, it will naturally sink to the bottom. In contrast, a Spirit Sea Realm expert is like a hollow iron ball, easily able to float on the water's surface. This is because their Dao Body accommodates more Mana. The body's weight is negligible compared to this vast spiritual power, thus allowing them to ride the wind and float like immortals!
