Liou Wenxin nodded slightly. "As far as I know, there really isn't a fourth method. But you can't just collect materials blindly. You need to analyze them first to make sure they're compatible with your skills. Even then, what you think is compatible might not actually be. It's very possible to gather a material and have it fail to trigger a skill upgrade, so luck is also a key factor."
Su Ze knew what she meant. It was just like how the Coral Worm Tentacles had triggered the upgrade for his "Needle Strike" skill; even now, he didn't feel the two were all that compatible.
He said, "My main focus should be finding materials that can trigger an upgrade for 'Knowledge is Power.' Do you have any thoughts on that?"
