It's true that Feng Sanyou has talent, but for him to create a massive array that Ares cannot detect and that can move the entire Blue Star with the insight and experience of a Seventh Transformation professional is almost impossible for Feng Sanyou.
Firstly, consider Feng Sanyou's use of the Power of the Primordial, which is a huge test for him.
