Tang Wulin’s martial soul had already become an extension of his own body, but his control over it during combat wasn’t great—he simply used it like rope.
Wu Zhangkong was able to clearly discern these issues, but he didn’t talk to Tang Wulin about them because he knew just how amazing Tang Wulin’s perception was. He had faith in that Tang Wulin would discover these flaws himself.
Moreover, Wu Zhangkong wanted to see if Tang Wulin’s bloodline power would gain any other effects when he reached rank 20.
But now, he didn’t even need to wait until Tang Wulin reached that rank. The answer had already presented itself.
If it’s like this, then the growth of his martial soul is something to look forward to.
