After ceasing the use of catastrophe-level power, Wen Wen felt a bit empty inside.
Having experienced that extraordinary strength, returning to the true order level, one could feel one's own weakness.
Clearly, the true order realm was far stronger than before, yet still felt inadequate.
Carefully examining his physical condition, Wen Wen identified the cause of the soreness.
It was because he was still too weak to withstand the catastrophe-level power for long periods.
The catastrophe-level power was akin to a barrel of liquid fuel, while Wen Wen, as a container, was only the size of a cup.
Even though this cup was much more resilient than a normal one, it still couldn't sustain for too long.
Wen Wen simply calculated that using ten minutes of catastrophe-level power each day wouldn't cause any damage.
But if it exceeded ten minutes, every second would inflict tremendous harm on Wen Wen.
