I understand that this is a "reincarnation" novel, and readers expected the MC, Feng Feiyun, to be more like Li Qiye in Emperor's Domination. However, this is not the author's intention. As readers will read on, the author will present clues to show everyone that everything is not what it seems. Feng Feiyun is not an "ordinary" reincarnation of a Phoenix Patriarch so naturally, he would not possess the wisdom or emotion controls shown in Li Qiye.
I do not want to spoil the big twist because it will raises more questions than answers, and only by reading the series will one get an acceptable solution. It is just discouraging to be privy to the fact that everyone's criticisms will be addressed by the author and was all part of his plan, yet due to the fact that not enough chapters are out, Spirit Vessel is facing unwarranted criticisms that might deter new readers.
