Just now, Mr. Old Count didn't take action at once, because he had scruples. He didn't feel any energy from Athena and Locke. There were only three possibilities.
The first one was that the two men in front of him were ordinary people and had never practiced. But since they could kill so many guards of the Brandon family, it was impossible for them to have no cultivation base, so this could be excluded. Second, they had treasures that could block others' detection, so he couldn't detect their cultivation bases. Third, they were super masters, which had far exceeded his cultivation base. However, even though he was at level 5, he could still feel a little aura from level 6 mages.
As for level-7 practitioners, he directly ignored it. It was rare in the whole Grimm Kingdom, not to mention in the Naton County. What's more, would level-7 mages be interested in their treasure house?
