Step 5 looks like a sketchy link to a google drive, but it’s ok, I’ve used it and many other have also with no problems. I believe it’s a customized version of Evony with the old link files to Aptoide AppCoins Wallet restored, so that they work again.
If possible, do this on an alternate/old device as you won't be able to play any new updates on this version of Evony:
If using an Android device, Clear Cache, Delete/Uninstall Evony from Google. I’m not sure this is necessary, but some people suggest search all, “topgames” on the device and delete all the old files first before proceeding with the instructions below.
If you are using Bluestacks, you can start a new, clean instance instead of doing step 1.
Download Aptoide APK mirror Evony v4.67.2: https://www.apkmirror.com/apk/tg-inc/evony-the-kings-return/evony-the-kings-return-4-67-2-release/#downloads
Go ahead and start the game, switch to whatever civilization your main keep is currently, do the craptorial, switch to your main account, and then close Evony.

Some people may also need to update AppCoins Wallet to the latest version to see the PayPal option in game.
Once you get it working again, you can purchase Pink Gems on this version, then go to the updated version and spend them on whatever you want.
