The other 2 people who did the reviews are downright stupid.
First of all, the idea is hin becoming a god through insence, he basically becomes a god through faith, and the more his faith, the stronger he get.
And the reason he killed the people from other organizations is bizzare? Did you even bother to read? The system gave him tasks for him to do it, and doing so would give him rewards, it would also increase more believer since they would consider him a righteous god.
Overall, these other 2 are people probably new to chinese novels, or else they wouldn't leave stupid reviews like this.
The journey and plot is good, the cultivation speed is decent and the world-view is similar to Journey to the West, overall its like a semi-fan-fiction but still good nonetheless.
