Chapter 18 - Great Demon King

As Rissy and I left the Future Castle, we were eager to test out the new powers of the Dragon's Heart. We had been given a powerful crystal that contained the essence of the Dragon's Heart, and we knew that it would grant us even greater abilities and skills.

"Let's try out the fusion skill," Rissy suggested, holding up the crystal. "It's supposed to combine our bodies and make us four times more powerful in every aspect."

I nodded, excited to see what the fusion skill could do. We activated the skill, and we felt our bodies merging together.

We grew larger and more powerful, and our bodies were covered in shimmering scales. We had wings, claws, and a deadly tail, and we felt like a true dragon.

"This is amazing!" I exclaimed, marveling at our new form. "We're even more powerful than before!"

Rissy grinned, and she activated another skill. "Let's try out the darkness-type skills," she said. "They're supposed to be incredibly powerful, and they'll help us in our fight against the Great Demon Emperor."

We tested out the darkness-type skills, and we were amazed by their power. We learned how to summon dark energy, and how to use it to attack and defend. We learned how to create powerful barriers, and how to teleport through the shadows.

We spent the next three months practicing and mastering the darkness-type skills, and we grew stronger and more powerful. We were ready to face the Great Demon Emperor, and we knew that we could defeat him.

Finally, the day of the Great Demon Emperor's attack arrived. We left the safety of the futuristic city, and we flew into battle.

The Great Demon Emperor was a massive, terrifying creature, and he was surrounded by a horde of powerful demons. But we were not afraid.

We used our fusion form and our darkness-type skills to fight against the Great Demon Emperor and his minions. We attacked with powerful spells and attacks, and we defended against their powerful blows.

The battle was fierce and intense, but we were determined to win. We fought with all of our strength and skill, and we gradually weakened the Great Demon Emperor.

Finally, with a mighty roar, we defeated the Great Demon Emperor. We watched as he fell to the ground, defeated and powerless.

We had saved our city, and we had saved the game world of Divine Rights. We were hailed as heroes, and we were celebrated by the people of the futuristic city.

As the days passed, we returned to our normal forms, and we celebrated our victory.
