The only item missing in the list of " heart of the White ape " was " heart of the ape-type monster (above transcendent).

Take the 'invisible sword bone' as an example.
During the tempering process, one would need to find a " cold Yin place where the earth fire and sea water intertwine ".
Roger thought about it.
It seemed that such a place could only be found at the bottom of Quinan's ice ocean.
