The way the Dragon-Tender Bloodline awakened within Meng Wanjun was extremely unusual.
It had nothing whatsoever to do with the growth of her cultivation, depending only on her attainments in beast taming.
When Meng Wanjun became a second-tier beast tamer, she had gained a divine ability from her bloodline called the Dragon-Tapping Art. This art could forcibly purify a demon beast's bloodline, and was particularly effective on beasts descended from dragons.
However, the Dragon-Tapping Art had its limits. It could not keep purifying a bloodline indefinitely, nor could it directly transform a flood dragon into a true member of the dragon race. Scarlet Flood Dragon, for example, now had a higher concentration of true dragon blood than ordinary flood dragons, so Meng Wanjun's Dragon-Tapping Art no longer worked on him.
Even for Earthrock, Li Ping reckoned the Dragon-Tapping Art's effects must have become extremely weak, if they had not already vanished entirely.
After all, the Dragon-Tapping Art merely added flowers to brocade. The Earthrock Python's true dragon bloodline was far too thin to compare with Scarlet Flood Dragon's, and naturally, his potential fell far short as well.
There was a reason Li Ping cared about Meng Wanjun's attainments in beast taming.
Aside from hoping she would awaken another powerful divine ability that could help Scarlet Flood Dragon achieve transformation, most of his concern was actually for her own good.
When she used the Dragon-Tapping Art to purify a dragon-descended demon beast's bloodline, she received feedback in the form of magic power.
However, that feedback depended both on how often she performed the art and on the purity of the beast's bloodline.
If she could nurture Scarlet Flood Dragon until he achieved transformation, the feedback from his true dragon bloodline would greatly increase her magic power, even if it did not
