Yi Weixing's sword didn't stop and clanged against the hard neck of the demonic beast. He pulled the sword downwards and sparks flew as metal traveled down the rock-hard skin of the demonic beast. The broadsword didn't do any damage as it landed empty at the end of the demonic beast's neck but it did manage to keep its attention. As the Poisonous Earth Dragon raged, more and more people arrived around it and started to attack it from all sides. The crystals on its back were the hardest part of its body so they were avoided but thankfully there weren't too many, meaning that it was relatively young.
Even so, its skin was so hard that no one was really doing any damage. And although they had found one of its weaknesses, its stumpy legs meant it wasn't very tall. So, not only was it dangerous to enter under its belly, it wasn't easy to fit so many people in it.
