I’m currently re-reading the novel and when Spectral Soul revives it is stated that reverse flow river is still in its original location, and his split souls had to go through it to come out of the door of life and death

so my question is how does it relocate to northern plains
Is it explained in the novel?

i know he removes the bronze skin gu and bones etc. but the strength phatoms are not mentioned
