There was no need for Jiang Chen's explanation. Ji San himself knew what true dragon blood meant. A family with a dragon bloodline understood the meaning behind that much better than most, regardless of how thin that bloodline happened to run. This was especially true for Ji San, since he'd read a plethora of ancient tomes on the subject. He was no stranger to the legends and myths surrounding true dragon bloodlines in particular.
In ancient times, the dragon race was one of the few races that reigned above all others. The bloodline that flowed through their descendants was diluted after generations of inheritance. It was one of the most depressing and helpless truths for the concerned parties. Both actual dragons and humans with dragon bloodlines had no solution whatsoever to the age-old problem of blood dilution; it was simply part of the natural order. It was impossible for bloodlines to become purer over time without genetic mutation.
