The brutal training method was an eye-opener for Mo Yan. She felt sorry for the beasts that were tormented, not a patch of fur on their bodies was left unscathed. She hoped Snowball would change the method of training, but it was not Snowball who opposed the idea first, but rather the beasts themselves.
Only after Snowball explained did Mo Yan understand that the beams of light from its eyes contained Spiritual Power. Although the beams would injure the beasts' all over, the points where the light entered were precisely the beasts' major acupoints and meridians. The refinement of these acupoints and meridians by Spiritual Power would result in a more perfect physical form for the beasts.
Even if they could not advance to become Spirit Beasts due to the constraints of the laws of heaven and earth and could not use Spiritual Power like Snowball, their physique and agility were not inferior to those of Spirit Beasts, and in some aspects, they were even better.
