After first trapping Li Ruhe, Ye Mo couldn't join his Illusion Cloud strikes together, but he was eventually able to use it however he wanted. The Illusion Cloud formation kill strike had developed to the point he could hurt Li Ruhe with the sword rays.
Li Ruhe was furious but he was getting more and more shocked. If he hadn't experienced what he had gone through today, he would never believe that a golden core state cultivator could hurt him.
But the fact was that this golden core state cultivator's sword technique was not only bizarre, but the sword rays that shot up from that purple kitchen knife had formed a sword ray formation. This formation was not fluent to begin with, but eventually it became more and more solid.
A golden core state cultivator could form his sword rays into the equivalent of a level three attack formation! How absurd was this? Clearly, he was at least a level four formation grandmaster.
