As Draegor was a martial artist, he only used his own body as weapon and nothing else. His self created system was not level based but still, it did not lessen how strong it had made him.
As his whole body started to radiate a very powerful aura, his muscles started to tighten and his body became bright red in colour. At the same time, his body itself became stronger and harder than even most divine grade weapons.
On his opposite side, Miyamura also got into a sword stance with his hands on his sword handle to face off against whatever attack the Otrefiona Emperor was going to throw. He could feel that the emperor's level was higher than his own but not by much. So there was no need for him to give up before even trying.
For his initial starting attack, Draegor did not hold back and used a technique. As this was actually a powerful attack, Miyamura was unable to face it without being serious himself.
