The Searing Sparrow Darts was a skill that was decent, but was lacking for Lin Mu compared to his other skills. But when combined with Wonder Seeker, it became several times better. The skill could be adapted into an arrow by the bow and even amplify its power further, thereby making it stronger.
Not just that but the bow could even attack on its own without Lin Mu needed to control it if he wished for it. As such, having more skills to use in conjunction with Wonder Seeker would be great. While he used the True Earth Heart Dao Embryo to create stone arrows, it was still from his Dao Skill and needed greater power to do so.
The metal arrows he created were also a bit vague since they were just made out of pure metal elemental immortal Qi and weren't an actual Qi skill. Thus having a Qi skill here would be a good choice for it.
For example, among the twenty Qi skills Lin Mu had picked out, there was one that was called as Elephant Shredding Bolt.
