Japanese Black Panther Trailer Gives Even More Infinity Stones Clues

Whatever T'Challa and Wakanda are hiding, it sounds crazy powerful. T'Challa says it is his duty to protect 'it,' and 'it' sounds very much like a singular item. Wakanda is an incredibly secretive and technologically advanced nation. In the teaser trailer, Wakanda was compared to El Dorado, but here it has more of an Atlantean vibe to it - with a secretive and powerful source of energy. The Soul Stone is the last of the Infinity Stones to be introduced in the MCU, and if the Soul Stone is in Wakanda, it could have been there for centuries or longer and would provide an explanation why the country is so much more advanced than the rest of the world. We haven't seen the Soul Stone's powers in the MCU yet, but given its name, it would also make sense for it to be hidden in such a mystical and spiritual place.
