Mark's interest was piqued.
Charles said, "Look at this territory of mine. With so many demon slave laborers, I'll definitely complete a solid, intact castle before the worlds of the Abyss and Purgatory collide."
"By then, I'll command hundreds of thousands of demons and hold fast within the castle."
"Even if devil troops come to attack, I'll be able to defeat them!"
"Just imagine it—countless devils and our own side will die in this battle, and you."
"As my sole merchant, wouldn't all the spoils from these demons and devils have to be sold through you?"
Hearing this, Mark also spotted the business opportunity. He said, "What do you mean, sir?"
Charles gave him an example. "All the military equipment from the devils I kill can be sold to you, and then you can sell it back to the devils!"
"You can also buy up the materials from the demons who die on my side and sell them to the devils!"
"Just think about it. What an enormous business this is."
"How much money will you make from it?"
Mark was utterly confused after hearing this. "But sir, wouldn't that be aiding the enemy? The devils are coming to attack you!"
"It would be normal enough for me to do this sort of business in secret, but how could this suggestion possibly come from you?"
Charles merely smiled. "Then do you think this business can make money?"
Mark nodded. "Of course it can make money—and a great deal of it."
Charles smiled. "Exactly. As long as it makes money, even if I lose this fortress in the end, it'll still be worth it!"
At that moment, Mark recalled how Charles was able to know such confidential information. There had to be powerful demons behind him, or some other channel.
