### Formations as Clan Foundations One of the most overlooked elements in Xianxia is the strategic value of **formations**. In this chapter, the *Netherdragon Lockheaven Formation* is explicitly described as a "clan guarding" formation. This isn't just a flashy attack—it's a permanent defensive infrastructure. In a world where a single Zifu enemy can massacre an entire tribe, formations provide a force multiplier that allows *multiple* weaker cultivators to pool their power. Ji Ning's decision to prioritize this over personal gear underscores his growing maturity: *repelling an invasion is more important than winning a single duel.*
