Dyon didn't have time to think. It was clear that his selfless state wouldn't do him any good here.
Of course, he had confidence in meeting Elder Bowa head on if he used his Demon Emperor's Will. However, he had promised his master he wouldn't. After all, Demon Emperor's will wasn't just a Divine level technique, it was among the best divine level techniques that existed, period. There was a reason that it was the staple technique of the Demon Sage. If Dyon didn't have the Demon Sage's blood essence, he wouldn't have any business using the technique at all.
Before Elder Bowa could gloat, Dyon burst out of the rubble. For better or worse, he still had a celestial level body even though he didn't practice any defensive techniques.
