Indeed, after vanishing from sight, the first thing to do was to block two moves of Emei's Moon Concealing Palm. This elementary palm technique was simple and direct, with no complex breathing patterns, only yielding two moves. By handling them, you could seize the initiative to attack and not give Fa Jue the chance to complete his incantation for a devastating spell! When it was time for close-quarters combat, that was when to spot an opportunity to switch to the exquisite techniques of the Great Luo Heavenly Scripture Finger to defeat the enemy!
Of course, this plan was merely Li Fan's improvisation. To fundamentally resolve the current peril and bring the Great Luo Heavenly Scripture Finger to a level compatible with the vanishing technique, a deeper understanding and proficiency in both skills was necessary.
