The intelligence of Abyss demons was far greater than Arthur had imagined.
After arriving in the Abyss, Arthur had conducted many experiments in his spare time, testing every aspect of the demons.
To his surprise, demons were not only highly intelligent, but surpassed many of the races he knew.
At the very least, their intelligence was far greater than that of ordinary humans.
They still couldn't compare to races like the Elves, but there was a reason for that.
The Elves had extraordinarily long lifespans. They often took decades to grow from childhood to adulthood, and Elves with Ancient Bloodline might need hundreds of years to complete the process.
After hundreds of years, even those who weren't especially clever to begin with would gradually become wiser simply through the passage of time.
At least compared with humans, who matured in just ten or twenty years, Elves were somewhat more intelligent.
Yet Abyss demons were also far more intelligent than humans, and overall could rival the Elves.
This result had taken Arthur by surprise.
He had assumed that a chaotic species like the Abyss demons, even if reasonably intelligent, couldn't be all that smart.
But it seemed that chaos was simply part of their nature, with little to do with a creature's intelligence.
After all, some madmen were often highly intelligent.
Nature and intelligence were separate things; they couldn't be lumped together.
The Abyss demons' intelligence was also evident in what stood before him.
Like this very castle.
Arthur had barely interfered in its construction. He had simply handed the demons some blueprints and information and let them figure things out for themselves.
And they really had figured it out.
When heaps of architectural blueprints and documents had been laid before him, Arthur's expression had been priceless.
His surprise aside, the
