In fact, the juvenile growth stage of many Spiritual Beasts is extremely prolonged, especially those with top-level bloodlines like Liu Wuxiang's Black Water Mysterious Snake, Long Qian's Jiao Dragon, and Ma Xingkong's Heavenly Horse.
If they were to follow the normal growth speed of these Spiritual Beasts, for Liu Wuxiang and Ma Xingkong to tame such Lifebound Spiritual Beasts would purely be inviting trouble.
According to the growth speed of the genius disciples from major Sects, under normal circumstances, genius disciples usually succeed in Core Formation before they are sixty, and advance to the Purple Mansion Realm around the age of two or three hundred. If by the time they become Elders of the Inner Sect their Lifebound Spiritual Beasts are still in their juvenile stage with hardly any War Power, that would truly be a joke.
