I think it just two ...one is the newest with no memories (kinda like a pendrive that we copy our data and store elsewhere) and senior Dan ( the real Shiwu that using a baby body that born centuries ago (so not his origin body for some reason) and being living in that body ever since with different identity " so he is kinda like the original data in laptop but we transfer it to another folder also in the same laptop" ) ..but idk what happen to the original body ..( I might be wrong tho , I'm not sure ..just expressing my view on this ┑(￣Д ￣)┍
The translation is confusing as heck
It basically the same data that have been categories into two type..and we save that that data into two different folder..so for fifteen.. it's yin and yang
So like , there are currently 3 fifteens then, the two dream versions and the irl black haired version? I'm so confused.
