When Vincent was still in the Tudor Kingdom, he encountered a Tier 4 Skill Book which is a requirement to learn a Tier 5 Skill.
It is the Skill Book that was used to test the Appraisers in the Guardian Auction House.
At that time, he was the only one with the ability to appraise it so he was able to get the job.
[ Skill Book: Demonic Body ]
[ Quality: Tier 4
Durability: 10/10
Description: A book bound by female human skin. It contains a full instruction manual to learn the skill called Demonic Body. Demonic Body is a prerequisite to learning a skill called Ethereal Demon Body, a Tier 5 Skill.
Remarks: This item can not be enhanced. ]
This is the first skill book that Vincent appraised, so obviously, he wasn't able to forget this item at all.
Now that he saw Brycen's body, he couldn't help but be reminded of this skill. Perhaps, if learning this skill doesn't require special materials, he would've learned the skill book as well using his Learn Ability of the system…
