How many Lotus Islands are left?

I want to make sure I have the count right.

Spectral Soul got 1
Giant Sun got 1 which is how he got involved in the anti Fate stuff

Feng Jiu Giu got 1 that’s Destiny Song and rank 8 future self

The one Paradise Earth got regret Gu on with rank 7 future self

I think that rank 8 time path Gu house back in volume 3 was from another 1, maybe not

How many are left?
