What Xiaowan possesses is not an ordinary Right Positioning Heavenly Phenomena, but one strengthened by the Power of Divine Seal Fragments. Things that other Divine Sons cannot achieve, Xiaowan might be able to. Just as Weichi himself has said, the Power of Divine Seal Fragments can turn the impossible into possible, achieving a breakthrough from zero to one. This is something Weichi knows best.
However, it's no wonder Weichi is finding this so unbelievable at the moment. Firstly, Xiaowan's proposal involves someone he loves deeply—the greater the hope, the greater the disappointment; to avoid disappointment, it's human nature not to hope from the beginning. Secondly, "summoning a spirit that no longer exists" sounds indeed counterintuitive. Until I saw Xiaowan accomplish such a thing, I too thought it was an impossible miracle.
