Q: This is one of the best books I've read in a while. It was very interesting, innovative and captivating. The descriptions of the different races and characters were all extremely in-depth and created a clear picture. Every time I read the book, everything else disappeared around me and I got transplanted to a different world. The ending is perfect, a great ending of book 1 and a cliff-hanger for book 2. Can't wait! Update: Just finished book 2, which was even better than the 1st volume, can't wait for volume 3! As others have mentioned, the book is light on LitRPG, which in my opinion is a big plus. The author touched on levels, level increases, different skills and capabilities, but otherwise left them mercifully short. In other books, there are only so many times one can read through character's skill and level pages before just "reading sideways" and skipping over them.
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
