On the second day, I hunted for quite a while in that spot but the number of monsters has started to decrease. The point that I earned was about 20 on the second day.
It was quite a good pace if you are aiming for Top-20 but it was a little low if you are trying to get into the Top-10.
In the novel, Hiro manages to get 163 points, Zion gets 155 points and Lisa and Sylvia get 140 points putting them in first, second, and third position respectively.
I decided to go kill one of the Rank-D boss monsters. A point of 120 would be enough for me to be pushed into the Top-10 rank.
Finding the Rank-D boss monsters' location was not a problem since I had a general idea of where they could be.
The only thing left to do was for me to go to that place and kill the boss monster. However, killing the Rank-D boss monster alone was very difficult. Heck, even a team of 10 students would get wiped out in an instant if they are not careful.
