Su Lin's Talent Secret Techniques have shown no progress.
That's because all his Talent Secret Techniques have reached the Extreme Heaven Realm, and transitioning from Extreme Heaven Realm to Forbidden Talent Secret Techniques requires a qualitative change.
Many secret art talents simply cannot support such a qualitative change.
Yet over these three billion years, Su Lin still pushed most of his Talent Secret Techniques to the peak of Extreme Heaven Realm, which is within the quasi-taboo level.
Especially among them, Change Heaven and Earth, Hunting, Eye of the Heavenly Calamity, Sky Wolf Howling Sun, Dragon Eagle Destruction Slash, Bewildering Step, Heaven and Earth Grieve Together, Ten Thousand Tribulations Light Prison, as long as there's an opportunity, they can step into the true ranks of Forbidden Talent Secret Techniques.
