Chapter 626: Untitled

Of course, although Roy's strength could eventually improve to an unimaginable number, this definition actually had its drawbacks.

This disadvantage was that he couldn't obtain a high degree of immediate combat strength at once.

In the early stages, every increase in his strength was negligible, and he had to use a large amount of time to exchange for more increases in strength. Roy calculated that if he wanted to reach the lowest standard of 666 times for the Deadly Sin-level strength, he needed to go through about 6,800 attribute increases. And each increase required 666 days, which was about 1.8 years. It would take more than 12,000 years!

Normally speaking, even as a long-lived demon, 12,000 years was too long for Roy. Beings like demons rarely spent long periods of time sleeping or other means of dormancy.
