Poison Gas Swamp.
One by one, the concealed reconnaissance demon eyes began to explore the surrounding terrain. Shawn himself simultaneously cast Flying Skill and Invisibility Technique, overlooking the entire Lizardman Tribe from hundreds of meters in the air. This area was full of swamps; it's virtually impossible for non-lizardman races to tread here, making stealthy approaches extremely difficult, as the soft marshland would reveal most movement traces. A wanderer trying to sneak here would end up sinking into the mire.
This is also why the defenses of the lizardman tribe turned out to be more lax than expected.
