Review Detail of The_Priest in Astral Pet Store

It was amazing at the start. But, soon enough, the author was hit by the stupid ray and it degraded to being undreadable dreg. When the MC gets strong, he starts killing anybody and everybody for petty, pathetic reasons. His personality is unbearably weak. If anyone tries to stop him, he kills them too. It's the classic chinese "the strong make the rules" dogshit. I don't understand how it went from a great novel to an intolerable, insufferable protagonist hundreds of chapters in.
