Genius

The Mathematician Genius told us. Though he is only a child, he is as talented as my pupil. The boy and I were both interested in the mathematical aspect of the Hundred Swords, so we started exchanging letters. Currently, I cannot find any better answers. I think it is better for me to seek help from the Genius.
But he is way too stubborn, so it will be easier to ask for his help by doing something for him.

Genius almost died just recently because of a Scout Spider Asle in Warrior Plain. After destroying <HFFFA7272>Scout Spider Asle<HFFFFFFFF> <HFFFA7272>east of the Warrior Plain<HFFFFFFFF>, go to the <HFFFA7272>Mathematician Genius, south of Tullan Square<HFFFFFFFF> and give him my message.

He is a young boy, but he pursues profit. He will only help me if we do something for him. After destroying the <HFFFA7272>Scout Spider Asle east of the Warriors' Plains<HFFFFFFFF>, go to the <HFFFA7272>Mathematician Genius, south of Tullan Square<HFFFFFFFF> and tell him what I said.

You defeated Scout Spider Asle? So what?
Oh, I see. Centergoras sent you here. The deed you have performed is not great enough to hear about the One Hundred Swords. You have to do something better. Think about it for a minute.
