If the disciples were a bit older, or had slightly higher cultivation levels, they could adopt methods such as planting Spirit Seeds or imparting wisdom, allowing the children to comprehend through their bodies and make progress while sleeping.
If the children had stronger cognitive abilities, or keener perceptiveness, they could also deepen their impressions by observing real divine beasts, achieving quick comprehension.
Those called martial arts researchers solve the problems that martial artists encounter; however, their services target children under the age of eight, making all assumptions about martial arts seem like wishful thinking.
The children are too fragile; even the most elementary impartation of wisdom and planting of Spirit Seeds could cause varying degrees of damage to their Sea of Consciousness, and the fierce aura of divine beasts could snatch away their souls.
