POINT OF NO RETURN – BACK UP SAVE
It’s highly recommended you back up your save BEFORE interacting with the Storyteller (PS5 Settings > Saved Data and Game/App Settings > Saved Data (PS5) > Upload > Upload to Cloud Storage -> Sync Saved Data = DISABLED so it doesn’t automatically overwrite your cloud save).
All that’s left in Mt. Zhenwu is to talk to the Storyteller who will bring you to the 4th region. After this point all of the 1st region is locked out of fast travel for the rest of the game and can’t be returned to (you can still visit the 2nd and 3rd region). If you have any unfinished NPC questlines they will break. Check at the shrine fast travel that all character icons are gone, except the Storyteller icon at Zhenwu Altar. Make sure you got everything in the 1st region. If you followed this guide from the start you will have everything and can proceed.
The Riddle Gates in the 1st and 2nd region also disappear after this point!
NPC: Storyteller (POINT OF NO RETURN)
Go back to the Storyteller and tell him “Continue forward” > “I press ever onward” to be taken to the next area to advance with the story. It teleports you to a ruined version of Worship’s Rise.
NEXT: Annalum

The backup here it’s only for those that have not followed the guide and forgot/missed some quests right?
In that case it’s posible to advance them till this point?
At least the White Robed Man it’s already broken if not done right. and will need a new game+ to redo.
Right?
Patch says
This is the first Backup save for multiple endings. If you want to farm for exp, you can do it before back up. All exp farming after this backup will be gone when you restore the save data.
