Forgotten Title Mc gets the chance to become an immortal

So I remember the mc is an elderly woman who's husband was lost at sea or something and they had like a crap ton of kids that had their own kids and so their family was huge. So all the kids were surrounding her at her death bed, but some female immortals came saying that her husband was actually alive and had became a grand leader and wanted to retrieve his wife for her to become an immortal and reunite with him. Does anyone know the name of this novel?

 

Cultivating to Become a Great Celestial ?? maybe

 

YEs, that's the one! Thank you : )
