Li Yuanba couldn't have anticipated that the place he entered earlier was actually this small building.
He wasn't too surprised; it was just that when he entered the hall, he didn't sense the presence of a spatial formation.
Reflecting on it now, the ancient sect probably used not an ordinary spatial formation, but refined the entire hall into something akin to a magical treasure.
This kind of technique is still in use today; the Treasure Pavilion and Book Collection Pavilion that Li Shiming took from the Yimu Cave Heaven of the Fuliu Sect are of this type.
However, the technique of this hall is not the same as those two architectural magical treasures; perhaps some refining methods from long ago have been lost.
Li Yuanba pondered for a moment and then attempted to re-enter the hall using the 'Divine Foot Skill'; the space movement once again brought him into the hall.
