First of all, the protagonist's Eight Extraordinary Skills were crafted by the Corpse Immortal Emperor based on stories from Earth through his continuous reincarnations.
I replied earlier that the Golden Finger is the Immortal Qi inside the protagonist's body, with the Eight Extraordinary Skills coming along as an attached bonus. Some people misunderstood my meaning, so I am explaining it in advance.
The protagonist's path is and always will be the Eight Extraordinary Skills. It is not that because the Golden Finger is not an Eight Extraordinary Skill, the skills themselves are mere bit parts and scraps (some people misunderstood and thought I wouldn't write about them later-truly there is no such thing sigh), and he will step by step refine and elevate the Corpse Immortal Emperor's creations into his own exclusive Eight Extraordinary Skills. The Eight Extraordinary Skills forged by the Corpse Immortal Emperor are not considered precious; they are merely a starting point and a guide.
Much like A Record of a Mortal's Journey to Immortality where Han Li's Golden Finger is the Heavenly Palm Bottle, yet the book genuinely writes about a mortal's journey to immortality, the Golden Finger in this novel of mine is Reincarnation, but it genuinely writes about the path of demonic modification and upgrading of the Eight Extraordinary Skills.
The protagonist's initial Eight Extraordinary Skills were crafted by the Corpse Immortal Emperor based on stories from Earth through his continuous reincarnations. For the sake of the Heaven's Chosen Plan, their power is neither too strong nor too weak-on par with a First-Generation Precious Technique, excelling in their bizarre trickery.
Because many of them have spells within the Perfect World that are not weaker or even functionally superior replacements, the protagonist will take them out to research and stir up trouble with trustworthy people. After all, constrained by their prototypes, even with the Corpse Immortal Emperor's reinforcement, many of the Eight Extraordinary Skills still lack competitiveness.
However, the protagonist will not casually pull out the extremely special ones, such as the most bizarre among the Eight Extraordinary Skills. For instance, the pure observation aspect of Grand Luo Insight is inferior to the Martial Dao Heavenly Eye and can be taught, but the complete version of Grand Luo Insight (involving the core profound truths of the Grand Luo Heaven portion) will not be taught. Nor will the heaven-defying Inner Landscape of Feng Hou's Mystic Gate be casually pulled out and taught.
Furthermore, possessing foreknowledge, even when the protagonist passes things on externally, the targets he selects are considered through the lens of the original work. When it comes to presuming innocence and worrying about betrayal, he would have to fight Chen Dong instead.
