I was bored, extremely bored, for I had done it all, I demon lord Tryfon Demetriou had done what everyone before me had failed, achieve immortality, vaporize half a continent, massacre humans to the point where they had to rely on people they summoned from different worlds, break the treaty between the 5 races(the elves, dwarves, humans, draconian and demons), I had even killed the dragon ruling the draconians gaining the title of dragon slayer, there was nothing more. I who adored battle was unbeatable.

there was nothing more to be done, no more battle to be had, I sighed once more as I drank the wine my firstborn son had gifted me for my three thousand-year reign. The moment I drank the wine, my body felt groggy, what is this? I'm getting drunk after one drink? This can't be right, just as i thought this the doors burst open and someone entered the throne room, it was my son and who looked not a day above twenty, and following behind him were my trusted generals. He was smirking at me, this crazy son of mine what has he done?

"Good morning father, it seems you are not too doing well?"

"Eduard, what have you done! What is the meaning of this?"

"Huh! You have ruled for far too long father, well nothing much I just gave you a mana suppressing drug"

When I heard that, I couldn't help but smile in excitement

"Hahahaha so the time has finally come, so you have finally gathered the courage to challenge me huh? It seems like these old bones of mine have forgotten the tension of battle that's why I let my guard down."

"That is indeed true father, so why don't you rest now and hand me the throne."

The moment he finished speaking I dashed forward, ready to strike. Even with my mana suppressed my physical abilities were still excellent. With a sword at hand, I slashed down, at my own son using my full strength, to which he responded by blocking my attack with his own blade.

"Do you think it would be that easy? Do you think I would simply hand you the throne? How about a little bit of excitement before I give it?"

"I would love to play with your father, but... I'm in a hurry to solidify my rule."

The generals that came with my son started attacking me with a barrage of spells. Without being able to circulate mana into my body I had zero resistance to magic. Still, I kept on fighting, as I smiled while laughing heartily.

I slashed down at my son, who blocked with his own sword. The floor cracked while the hand of my son trembled a bit.

"As expected of the strongest even without mana your strength is unparalleled." I kept on attacking my son after he said that. Yet even with all my effort without any mana, muscle strength alone cannot bypass someone as strong as my son.

soon after attacking, I became exhausted, even without my mana I might have been able to get away with this battle if it was just my son but with the demon generals joining in I had no choice but to fight to the death, so this is what defeat feels like huh?

"As expected of the strongest demon lord father to last this long without mana is truly something remarkable, its a pity but this is your end."

The strongest Demon Lord conqueror of the world died at the hands of his eldest son, and even in the face of defeat he died standing with a big grin on his face.
