Vol V Chapter 223

Leon's sword looked similar to the one he had used in his first attack previously, but they were actually vastly different. When he had first started fighting with the dragon, the dragon's powers were that of the mid-legendary level. If it had not been immortal, Clito and Asner as a duo could have easily slain it. However, now, the dragon was already at the demigod level. Even if it was at the weakest demigod level, a demigod was still a demigod and higher than that of legendary levels. Just as how those of the advanced level had to group together to fight legendary-level individuals, legendary-level individuals also had to work together if they wanted to defeat a demigod. This was the reason why the Legendary Masters had worked together to attack the dragon, and they still had some difficulty then. If Leon was not present with Sui Xiong's artifacts, they would have perished long ago.
