Xiaobai's Defense War invites players into a strategic challenge where defending your camp against relentless monster attacks is paramount. Monsters are a direct threat, capable of destroying your vital buildings.

To bolster your defenses and economy, players can engage in resource management by planting crops and raising animals to synthesize food. This food can then be sold for gold coins, which are crucial for upgrading your defense towers. Enhanced tower properties are key to repelling increasingly powerful waves of enemies.

Beyond combat, player interaction plays a role. Engaging with NPCs through conversation and gifts can increase your popularity. Reaching certain popularity thresholds unlocks additional functions from specific NPCs, adding another layer of strategic depth.

Building placement is restricted to designated areas: around the camp, near mining machines, and within the dedicated infinite defense mode. This limitation requires careful planning to optimize your defensive layout.
