In a classical natural economy with extremely low risk resistance, the systemic environment was full of unpredictable variables and disorderly disasters. famine, warfare, plague. A single isolated social node, when struck by such system-level shocks, could be instantly annihilated. To raise the baseline probability of survival, the smallest viable unit had to form the tightest possible two-person alliance to share the formidable burden imposed by the environment. The system urgently needed a binding norm capable of resisting external rupture.

Moistening each other with saliva (xiang-ru-yi-mo) is an extraordinarily resilient micro-alliance mechanism against disorder. It goes far beyond the needs of animal reproduction, insisting that in adversity. when resources are utterly depleted and the situation is desperate. husband and wife must execute absolute resource sharing and mutual spiritual support. This is a mechanism that irreversibly fuses two independent capacity nodes. Under severe conditions, any reservation of self-interest or calculation of sunk cost by either party would cause the alliance to disintegrate instantly. The system therefore compels both sides to lay down all their cards and make the highest-grade trust pledge. This direct welding and life-or-death compact between micro-nodes dramatically raised the survival rate of the most basic living unit,. It also provided the vast, heavy structure of the agrarian empire with thousands upon thousands of highly pressure-resistant, nearly indestructible bottom-layer physical load-bearing units.

Mutual devotion lasts because people keep using it. It begins in concrete situations, then passes through teaching and public habit until it becomes a steadier civilizational capacity. This chapter follows how that capacity is preserved over time.

Mutual devotion also enters household life and public institutions. Different people use it, explain it, and protect it in their own settings. The husband-wife covenant and family micro-foundation of shared hardship and unwavering togetherness. That is why it can speak to other chapters while still keeping its own boundaries.

Its importance lies not only in naming an idea, but in showing how people, families, social order, and civilizational values connect. It gives the reader a first doorway into the logic of this chapter. Through it, abstract values enter concrete life.
