Ling Xiao has many attack techniques, but each has its specific purpose.
Such as the Tai Chi Eye's God Tomb Eye, The Eye of Burning Heaven, Sword Spirit Eye, Eye of the Immortal Pot, and Eye of the Holy King.
They all have their specialties and can work wonders in certain battle conditions.
But there is a limit to how much they can boost combat power.
The Three-leaf Demon Pupil is the same, serving as an effective supplementary attack.
For a martial artist like Ling Xiao, who is adept at using skills, these supplements are necessary and very beneficial, yet there's no need to use them every time. Utilizing them in unexpected situations can produce amazing results.
Of course, in terms of attack power, the most terrifying currently are the Heavenly Demon Incarnation and the Golden Crow Transformation.
These are the two most formidable transformations under the Mysteries of Light and Shadow.
