- **Qi in Martial vs. Cultivation Contexts**: Li Feiyu uses "true qi" (真气) in the wuxia sense—a purely internal martial energy that can reinforce attacks, increase speed, or block damage. This is fundamentally different from the "true qi" (also 真气) that Han Li cultivates in the Eternal Spring Art, which is a spiritual energy linked to longevity, spiritual roots, and the cultivation path. Han Li *cannot* use his spiritual qi to power martial techniques, which is why he specifically seeks a technique that requires no true qi at all. This distinction is crucial for understanding the martial-cultivation boundary in the Mortal Stream. - **The "Riding the Tiger" Dilemma**: Han Li's internal line, "I'm riding the tiger now" (骑虎难下), is a classical Chinese idiom for a situation where you cannot stop even though you desperately want to. In the Mortal Stream, it perfectly captures the essence of a cultivation project gone beyond the point of return—once you start absorbing spiritual energy and expanding your meridians, the material costs and physical momentum lock you into an irreversible trajectory. Han Li cannot simply "throw away the formula" without risking his foundation or exposing his secrets. - **Private Instruction Economy**: In the Seven Mysteries Sect, the transmission of martial arts is tightly controlled. Seven Peaks Hall techniques are not publicly available; they are earned through status, lineage, or—as in this case—illegal private trade. This reinforces the sect's internal economy: knowledge is a scarce resource hoarded by the upper hierarchy, and any leakage below the elite tier is a capital offense. Li Feiyu's willingness to teach Han Li is not just friendship; it is a sign of his own estrangement from the sect's orthodox power structure.
