Last year, Pang Lei, not yet fifteen, had his spirit root fully formed and participated in the annual sect trial, becoming an Inner Sect Disciple and entering the Dharma Transmission Hall for cultivation. This was perfectly normal after not seeing him for over half a year, hence the surprise.
Even Xu Xiaochun and Guo Wanzhi, who interacted with him daily, were occasionally surprised by Li Ji'an's changes whenever they finished a closed-door alchemy session.
Li Ji'an speculated that this was most likely the effect of the Source Supplement Pill.
Firstly, it made up for the spirit veins before the age of eight, affecting not only the subsequent five years, but also the first eight years, leading to significant changes.
Secondly, the Source Supplement Pill he refined in his past life was based on his Wood Element medical skills, infused with abundant Wood Magic Power.
