Due to the speed of Ethan’s Water Snakes, they outpaced all the Adventurers who were trying to run to safety.
Unlike the others who could only run on the ground, Ethan’s water snakes could crawl on the walls, as well as on the ceiling, giving them better mobility without impeding others in their escape.
The last thing that Ethan wanted was to be caught in the rush of panic-stricken Adventurers who might lose their footing and trip.
If that happened, a domino effect would happen as the Adventurers running behind them would bump into them, making them fall on the ground as well.
This was something he wanted to avoid at all costs, so he decided to summon the Water Snakes for faster transportation.
Nicole, Samantha, and Lady Johanna didn’t need to worry about breathing inside because he made sure to leave a bubble of air inside the body of his Water Snakes, giving them plenty of air to breathe.
