Regarding the detection of bloodlines, there has always, in fact, been a lack of efficient and precise methods.
But not none at all.
The simplest method is visual inspection.
The principle is also simple, with different bloodlines generally possessing distinct external traits.
For example, those with an Elf Bloodline often grow a pair of pointed ears and are strikingly beautiful.
Those with a Dwarf Bloodline typically have a short stature, well-developed muscles, and a fondness for drinking.
People with the Cathedral Bloodline often have a pair of beautiful silver-white pupils. Those with a high Bloodline Concentration may even grow a pair of snow-white wings on their backs.
The method of visual inspection is straightforward, but it has many flaws.
Many bloodlines do not display external characteristics, or lack them entirely, which can easily lead to misjudgment.
The factor of Bloodline Concentration also makes visual estimates inaccurate.
