( Author: Sorry for no chapter yesterday, I unintentionally released it for my other novel :(
Thank to how safe and convenient things were in Doncaster, the players had no issues with growing stronger and constantly reaching new realms. None had faced a bottleneck so far, and they were able to evolve relatively easily after reaching the peak of the realm and finishing the challenges that the system would give them.
It was only now, after people had reached Tier III, that this started happening. For some people, it happened even before the peak of the realm. Thanks to the system, they were able to immediately find out about it and start slowing down their leveling progress because as the more powerful they became, the more difficult it would be to use mana to reinforce their bodies and allow them to continue leveling up.
