Although Zhao Hai still didn't know where the demonic Sword Saint came from, Zhao Hai was sure of one thing. The demonic Sword Saint was definitely not from the sword spirit world, because the laws of the world where the demonic Sword Saint was from were half a level stronger than the sword spirit world.
This was also what Zhao Hai found the strangest. He really wanted to know what the realm where the demonic Sword Saint lived was like. Why was his realm half a level stronger than the sword spirit world's laws? this was too strange.
