Venomous Serpent Swamp

At this moment, Ethan had ventured into the territory of the Venomous Serpent Swamp. 

Though seldom having traversed swamplands before, Ethan was well aware of their notorious reputation. 

He knew that the greatest danger in a swamp lay beneath one's feet.

Swamplands, with their deceptive terrain, pose a significant risk. 

A misstep could result in sinking into a quagmire, and without assistance, escaping such a predicament is nearly impossible. 

Therefore, Ethan proceeded with extreme caution, constantly vigilant of the ground beneath him.

Moreover, the Venomous Serpent Swamp was infamous not just for its treacherous marshes but also for its abundance of poisonous snakes and pythons, a fact clearly indicated by its ominous name. 

The swamp had virtually become a haven for serpents.

Thus, in addition to the fear of falling into the swamp, Ethan had to be wary of encountering snakes at any moment.
