What's even more wonderful is that with the "Confucian Classic" present, when Senior White is ready to inherit the Scholarly Sage's Eye, he can complete the ritual by using up Song Shuhang's "path to immortality" — just like how the Sage Secret Technique almost depleted Daoist Senior's "immortal path" previously.
Senior White doesn't need to consume his own immortal path at all.
Plus, the Sage's eye can be resurrected through the "undying fat whale golden core".
This means... theoretically, Song Shuhang could sacrifice his path to immortality over and over again, allowing the Scholarly Sage's "innate skill" to be inherited by more people.
His own daughter, disciples, and members of the Nine Provinces Number One Group are all potential inheritors.
After the sacrificial ritual is completed, Song Shuhang himself can retain fragments of the "path to immortality".
When the time is right, these fragments can be assembled into the true "Second Immortality" that Song Shuhang desires!
