Even if the ground was dirty, Riser didn't care, especially after he had won against the Great Red and even devoured it.
"Degenerate..."
Somehow, he understood why the name of this ability was so wicked. After all, as long as he could absorb something into his body, he would become stronger. When he is addicted to the feeling of getting stronger by devouring the other, it would mean that he would degenerate, especially when he would become a strange creature of the combination of many.
Frankly, he thought that turning his opponents into Mocking Gear was the best way, but he didn't expect that he could use his "Degenerate" to devour others.
Yet, frankly, he might not use this ability for a while, especially since the one he devoured was the strongest being in his world, the Great Red.
As the strongest being, naturally, the improvement he gained after he devoured the Great Red was so great, especially the improvement in the amount of energy within his body. Moreover, he also gained a variety of abilities from the Great Red.
If there was trouble, it would be that his race was no longer a pure devil. Instead, he was a combination of a devil and a dragon.
Well, he got stronger, so it was good, right?
Yet, due to this, he gained weakness from the poison of Samael.
Still, if it were others, they might be troubled, but him?
The poison was simply meaningless to him.
Not only could he use "degenerate" to remove the poison within his body. More importantly, his fire ability would burn all the ailments and everything negative within his body. Lastly, with the "Ruler," everything that hurt him would only make him stronger.
Even if he wasn't pure a devil and also a dragon due to devouring the Great Red, it didn't matter. Though he had to say, it felt quite ironic when he became an existence that he hated the most.
Yet, even if he had devoured the Great Red, it didn't mean that he had fully digested it. He needed time to fully digest this beast into his body, but with the power of "Gutsu Gutsu no Mi," which made him a furnace devil, it shouldn't take a long time.
At this moment, he just wanted to rest, sleep, and enjoy a quiet moment. He wasn't sure how many times he had died. Even if he had won in the end and couldn't die due to his immortality trait, he was still exhausted.
Nevertheless, when he thought about the six figures who had given him trouble, he knew that he couldn't make them wait as he knew that it was time for him to mess up their lives. He wouldn't kill them so easily, and he was going to give them the taste of pain for what they had done to him.
Especially those dragons.
By now, he knew that Tannin should have gone on a rampage in the Underworld, but he didn't care. Moreover, no one would be able to link him with Tannin, especially after his heroic act of sacrificing himself to defeat the Great Red.
Yet, unfortunately for them, he wasn't defeated, and he gained his victory!
Moreover, he had become stronger, and he became the strongest being in his world!
Still, if possible, he wished for someone not to trouble him anymore. Once he killed those six dragons, he hoped that everything was over.
Yet—
Riser sighed since he knew the greater the expectation, the greater the disappointment was.
However, he was the strongest now, so no one should be able to defeat him, right?
"Let's check the rewards first."
[Congratulations, you have received five random rewards.]
"Thank you."
[Good job. I am proud of you.]
"Thanks again."
Even if the system was kind of a bastard in the beginning, he was glad to have it now since if he didn't have it, he knew that his life would be in despair and let his life be messed up by the main protagonist.
However, Issei had died.
Still, there were many cockroaches that were still living well, and he knew that they would be a perfect companion for Sirzech and Issei so they wouldn't be lonely in the eternal abyss.
Riser sat up as he opened all of his rewards.
[Congratulations, you have received a "Sunshine," "Pika Pika no Mi (Complete Version)," "Satanael," "Thought Acceleration," and "Chosen One."]
When he saw all of his rewards, he thought that it was amazing.
'As expected of the strongest being.'
When he saw all of his rewards, he was completely convinced why the Great Red was called the strongest being.
However, that title was taken by him now.
Still, he looked at his first reward, "Sunshine," which was an ability that empowered him during the day. As long as the sun rose, he became stronger, and when it was midday, he became the strongest. Moreover, this power also allowed him to manipulate light and heat.
Well, the manipulation of light and heat aside, as he could do it without the help of "Sunshine," was a great power, especially because it made him stronger during the day.
Moreover, he knew that he could develop this power further.
"Let's check the next reward."
Pika Pika no Mi.
Riser directly ate this Devil Fruit, and he gained the ability to manipulate light and became a light.
Now, he could even move at the speed of light.
"....."
Wasn't he the strongest now?
Well, he had eaten so many Devil Fruits now, so it was hard for him to get excited, even if the power was amazing. He quickly looked at his next reward, which made him dumbfounded.
Satanael.
It was an ability to turn his body like a nuclear fusion to create more energy. This allowed his energy to increase dramatically, and no matter how much he consumed, it would not decrease. This allowed him to fight almost indefinitely without running out of energy.
Riser tried to use this power, and as expected, he could feel his body filled with a limitless power.
However, he could imagine that by using this ability, he would increase the speed of the planet's death.
Still, he didn't really need to use this ability since, after devouring the Great Red, his energy was as good as limitless.
The Great Red is the void dragon.
Within the void, everything was his.
"..."
Riser suddenly felt speechless at how strong he had become.
Probably, nothing could become his opponent in this world.
Still, his next reward was also quite amazing.
Thought Acceleration.
By using this ability, it would significantly increase his thought-processing speed. Moreover, as long as he trained, the acceleration would increase even further, even hundreds of millions of times or more.
"Then, the last reward."
While he wanted to check more, he wanted to check his last reward first.
Chosen One.
"..."
Riser fell into silence and realized this was an ability to turn him into the main protagonist.
In other words, when he returned, all of his enemies would be destined to lose no matter how hard they struggled, especially when fate was in his favor; supporting him and doing everything would make him the last one who stood up.
"Fufu..."
He wanted to laugh somehow after he gained this new ability.
Did he gain this ability because he killed Issei?
Well, it didn't matter since it was time for him to return to everyone.
The space was open, and he walked out, ready to give a nightmare to all of his enemies.
"Oh, right!"
Before he left, he needed to make himself appear beaten up, or else many would be suspicious, right?
