The appearance of the Bone Dragon King signaled that the top-tier powerful wraiths of the Wraith Kingdom had begun to emerge on the battlefield. Alongside Ross, the Hell Knight, and those four powerful wraiths, there was no doubt that they were all immensely formidable, possessing cultivation that could rival the Hall Masters of the 6 Great Sacred Temples.
On the human side, although the Federation's 6 Great Sacred Temples had a numerical advantage in terms of 9th Rank powerful experts, it seemed that they held no advantage in the number of higher-level experts.
Surpassing 9th Rank Level 3 was considered top-tier. And at 9th Rank Level 5, one was essentially at the pinnacle of human power. The Hall Master was only at this level. Of course, humans also had powerful godly vessels, equipment, and mounts to enhance themselves. But at this moment, when the Wraith Kingdom began to go all out, it seemed that the supposed advantages of the Federation weren't that significant anymore.
