Name of Game: King of Rebirth
Play Store Link (If it's a paid app, the apk): https://play.google.com/store/apps/details?id=com.rsg.kor
Version: 1.0.60
What cheat? Health, xp, gold...: Gems
Have you tried cheating this game? What happened?: Yes. I can successfully hack every rss via classic find and replace with negative method, in vault.
Comments: I've tried many methods from video tutorials from here, or other solved requests, nothing happened. I can change displayed gems value, and when I do this the price of an item turns white (I can buy even if I don't have enough gems), but when I press BUY it says insufficient gems.

As it is server side it may not exist an hack for gems, but a new look onto this may be helpful. Thanks a lot!
