Qi Peijia
We all know that the Primal Chaos Mysterious Energy will eventually fall into Han Xiao's hands. The real question is whether anyone finds out that Han Xiao got it. If, somehow, Han Xiao is able to conceal this matter, it'll be an excellent way to secretly boost Hila or Aurora. If someone finds out, then there'll be another mark against Han Xiao in everyone's books. This won't be good for his development during Version 4.0 and beyond at all.
