After the two sisters had dealt with their own matters and returned, Du You sternly lectured both of them late into the night. As a result, the plan originally set for the next day had to be postponed to the third day.
At the academy, because the Undead World had reopened, they once again started calling on students to enter. That world was filled with a multitude of enemies, which could provide copious amounts of Crystal Coins, benefiting the students' growth greatly.
However, because there were so many enemies, that world was also very dangerous.
Therefore, even with the academy's call, students without certain strengths would not easily enter. Moreover, to control that world, the academy only allowed its own students to enter and absolutely forbade outsiders. They even signed contracts with the students, stating that the coordinates they obtained could only be used by themselves or sold to the academy, and could not be taught to others.
