The level-up of Little Black and Little White was completely beyond Han Fei's expectations. On this trip to the Thousand Star City, Han Fei never thought that he would have this additional gain.
Back when he was deducing the Soul Searching Technique, the need for further deduction had turned into Chaotic Qi. However, he didn't know what Chaotic Qi was back then.
However, there was no need to ask in advance. It was just like one's realm. When one reached it, he would naturally be able to understand it. It was a matter of course. If he hadn't reached his realm, forcibly reaching it would be harmful.
This time, although the information of Little Black and Little Whitehad changed after the breakthrough, no new abilities appeared, which made Han Fei rather regretful.
