Sol was still planning on cultivating his bloodline while trying to understand them, but he wasn't going to rely on them in battle and risk people digging into his background.
Using it in front of everyone while fighting Elder Hyun-Joo and the Sand King was one too many times. Thankfully, he could trust Yoon-Jae and the others, and due to how simple-minded everyone in the Tribe was, they didn't even question how Sol could transform like them. Rather everyone just started calling him cousin. In their eyes, Sol might as well be a part of their Bloodline Tribe.
With all of that being said, with his talents in Martial Arts, that alone should be enough for Sol to suppress everyone in this generation. But thinking about how he would need to use his bloodlines if he wanted to compete on the same level as the other geniuses if he went back to Jianghu now, was slightly humiliating for him. After all, his talent in Martial Arts was the only reason why his Master had taken him in.
