The ancient Hydra Xu Dela showed its body outside the wormwood, about ten blades high. Unlike ordinary snakes, Xu Dela's body was not covered with scales, but was studded with blue thorny bumps similar to thistles, bulging and robust like a gigantic oak wine barrel, with two limbs as thick as stone piers. At first glance, they looked like two blue elephant legs. Nine enormous triangular heads each had a neck. Among them, the middle snakehead was the most gigantic and terrifying. The red snake tongue frequently made hissing sounds, and occasionally some heads exposed their sharp fangs to gnaw at each other.
A mocking laughter, like an owl's hoot, was rapidly approaching as well.
