A-level's [Bullet Time] upgraded to S-level's [Space-Time Stasis], consuming 5000 points of Divine Energy.
2200 points of Divine Energy remain, insufficient to upgrade other A-level Skills, now I have to slowly accumulate Divine Energy again.
One Danger Level 7 deployment, all Main Quest and Challenge Task completed, usually rewards only 3600 points of Divine Energy.
Most Superpower Users do not have the ability to complete all Challenge Tasks.
One can see how rare S-level Skills are.
This is still because Lu Heng has the [Divine Evolution] Talent. For other Superpower Users, to upgrade to an S-level Skill, not only do they need 5000 points of Divine Energy, they also need to complete a World Task to choose the Skill upgrade reward option.
S-level Skills have a fundamental difference from A-level Skills.
Because S-level Skills belong to the power close to that of a Demigod.
