Thanks to the training with Sebastian, Lucifer and Nothing's fighting techniques, strength, endurance, stamina, and many other things had improved greatly.
Now, their attacks had almost no extra movements, and their movements had also become much more graceful and steady.
If Lucifer and Nothing were just insignificant ants before, then they must be dogs now. However, they were still weak but at least they had become much stronger than before.
Although their level was not yet that of a master, Lucifer and Nothing would soon reach that level. Probably in a few months if they kept training with Sebastian.
In addition, thanks to those harsh training sessions, Nothing and Lucifer's coordination had also become much more harmonious. It was as if they were one and could predict what their comrades were going to do.
If Lucifer wanted to attack, Nothing would distract the Centaur for him.
