Lu Chuan currently has three basic skills.
They are Basic Crime Scene Photography, Basic Footprint Analysis, and Basic Fingerprint Identification Analysis.
The Eye of Truth is a passive ability, a starter pack rewarded by the system, with no possibility of enhancement.
Fingerprint Collection and Skeleton Identification Analysis are both at the intermediate level.
Therefore, this time's Skill Upgrade Card can only be used on Crime Scene Photography, Footprint Analysis, and Fingerprint Identification Analysis.
The three skills all greatly benefit Lu Chuan.
Crime Scene Photography, though it seems the least useful for solving crimes among the skills,
Lu Chuan discovered issues through crime scene photos in the Zhang Wen case.
If Lu Chuan hadn't acquired this skill then, the photos taken might not have been so complete.
The clue of cigarette ash might have been missed.
The Basic Footprint Analysis had made significant contributions to several cases Lu Chuan participated in.
