Righteously

Hearing his supposed father-in-law's words, Dyon felt a headache coming along. This was a man who personally slaughtered a Higher Existence Embryonic Infernal Beast in his prime. If he really decided that the first thing he would do when he came back was assert his authority as Amphorae's father, Dyon could only grit his teeth and deal with it, especially since his body wasn't in peak working condition right now. 

'Goddammit. How about you be a little grateful that I built you a body? If not that, be grateful that I allowed you to use the Soul Tome free of charge. What a petty man.' 

It wasn't Dyon's fault that he turned out to be the Demon Sage's prophesied successor. What the hell did it have to do with him? He hadn't even been born yet. 

Unfortunately, no matter how Dyon willed it away, the fusion was happening without a hitch. 

The demon sage's mystical world trembled. A surge of blood red qi swirled violently, piling into the Demon Sage's vessel.
