I am asked to find the area D. Since the traingle is displaced by "a" steps on the y-axis, I should be able to get the same area if I bring the triangle down to the axis, so that the bottom of the triangle is adjacent to the x-axis. My answer is wrong anyways, as the book says the area D is e^3. Where did I go wrong?
Guys, when I finished catching up to the manga I really wanted to continue the story, so I went to NU and found that I can't find the volumes of the LN/WN of this series. The Mediafire link on the TL's site doesn't work on my phone for some reason, torrents are blocked here and I don't have digital money to spend on a VPN, and the old Wayback trick I did to read Slime Tensei series back then doesn't work as well.
So please, a link to an alternative website or even a different file sharing site like MEGA is fine as well. Thank you.
