In a simply furnished room, a candle flame flickered softly.
Lü Zhong sat at a table, picking at a piece of pork and occasionally scooping some Spirit Rice into his mouth. His eyes remained fixed on the Qi Observation Skill experience book in his hands.
Although he had read less than half of it, he already felt the book was well worth the purchase.
The opening of *One Hundred Practical Insights on Qi Observation Skill* detailed the different types of Spiritual Qi. Besides the Immortal Spiritual Qi, Demon Spiritual Qi, and Demonic Spiritual Qi that Lü Zhong already knew of, it also mentioned Medicinal Spiritual Qi.
This so-called Medicinal Spiritual Qi was a special type of Spiritual Qi formed when the medicinal substances within a Spirit Medicine merged with nature's spiritual energy.
