Demon Lord: Erotic Adventure in Another World - Chapter 7: Delinquent’s First Battle - Awakening Nature!

When Yohan woke up in the morning, he had a beauty in his lap and in his bedroom. It was like a dream come true for him until reality struck him.

It was then he remembered that he had been cursed by a goddess in the game he had been playing before sleeping. In his sleep-deprived state, he had offended the goddess and as a result, he had been cursed to become a 'no-good' man who could only provide 'support' to the 'heroines' of this world.

Thinking nothing of that curse beforehand, Yohan went to sleep, only to find his world-changing from that day onwards. His normal and mundane life was no longer going to be as such as more and more fantasy creatures began to show up.

And a female voice awoke him with a notification

*Ding dong ding.

Congrats on unlocking the fiction system. From here on, the user will experience the full scope of the logic of the fiction world. May the user use his PP and conquer everyone.*

And it was then Yohan realized - he was no longer in a world governed by science but one that followed the laws of magic. And the only way to survive was to utilize these so-called 'laws of fiction' to his advantage.

And the best and worst part of it all? The more he let his desire go, the stronger he became.

“Obtaining the topmost degree of talent in sword arts in the world requires giving up 72 years of lifespan, which leaves you with only five more years of your life. At the same time, you will never be able to feel love, kinship, and friendship, and you’ll end up leading a lonely life until your death, unable to procreate, or to have any descendants.

“From now onwards, everything related to happiness in the human world shall no longer be of your concern. Are you willing to accept this?”

“Hahahaha, I’m already alone bereft of all support, my hopes dashed to pieces, shouldering only absolutely irreconcilable grudge and hatred, why would I disagree? Why would I not want it? I couldn’t ask for anything better!!”

His sword sweeps across the Divine Continent for seven days and nights, moving 90,000 miles through the starry skies, unhindered.

He slays saints and buddhas in Heaven, slaughters demons and devils in Hell, sweeping away all the grievances in his heart!
