Yan Ming'an's eyes narrowed slightly as he realized that his opponent was indeed only at the Mountain Sea Realm, as he could not sense any divine energy from them.
Of course, it was also possible that the opponent had just entered the Sun Moon Realm and had not yet had the chance to condense their divine seed.
However, the opponent's primal force was immense but lacked refinement. Even for a practitioner newly entered into the Sun Moon Realm, their primal force would not be so crude.
Despite the incredibility of the situation, Yan Ming'an knew that the opponent's true realm was indeed only at the Mountain Sea Realm.
With such power at the Mountain Sea Realm, not only did they withstand his Invincible Golden Body's attack without dying, but their aura remained completely unchanged. Aside from a shattered sword, they suffered no other damage!
Was this really the Mountain Sea Realm?
