After Russell contracted with Unicorn Polly, he boldly and vigorously trained until he achieved perfect heart-mind synchronization in just half a year.
However, it took him a full year and a half to barely reach the same level of synchronization with Harpy Dragon Hape, who also possesses pseudo-dragon bloodline and comparable intelligence.
This pace would be considered rapid for ordinary Phantom Beast Knights.
Eric, who contracted with a phantom beast before Russell, has yet to achieve perfect heart-mind synchronization with Kevin the Gold and Silver Wolfhound.
The exceptionally talented Katie, though she had a good rapport with Red-Eyed Mouse King Jerry, also faced numerous stumbling blocks in her heart-mind synchronization training.
Thus, it's clear that the cultivation of Phantom Beast Knights is no simple task.
