Xin Feng acted a bit confused in front of Maeda, and while he did that, he asked Balance if what Maeda told him was true. As a reply to his question, Balance didn't tell Xin Feng if it was true, but explained why it was true instead. The reason why there were black veins on Xin Feng's head was because of how concentrated the chaos energy was, Balance told him. Such a sign meant nothing dangerous, and would never be as well, since Balance had the capability to make sure that every bit of chaos energy got absorbed by Xin Feng without a single mistake.
