All the gu masters fighting for their lives to obtain resources in life and death missions and meanwhile the refiners are at peace not even needing to leave their homes to make fortunes
Ahh life is unfair
1- I think there are less than 30, taking into account that Gu Rank 9 are incredibly difficult to refine.
2- At least one Gu for each existing path
3- My favorite path is the robbery path, this path is simply broken. Thanks for the chapter~
