Can You Give Me Twenty Bracelets

When Evan reached the city gate he saw many hunters were leaving the city.

Last night Edward sent some information to all the students which he read while coming here.

According to information, to stop the monster tide tens of different kinds of formations are created outside the city.

One thousand kilometres away from the city walls, a formation that can stop S and A+ rank monsters is created.

Eight hundred kilometres away from the city walls, a formation that can stop A rank monsters is created.

Six hundred kilometres away, a formation that can stop B and B+ rank monsters.

Four hundred kilometres away, a formation that can stop C and C+ rank monsters.

Two hundred kilometres away, a formation that can stop any monster below C rank.

With the help of these formations, hunters will be able to create different zones for the different levels of monsters.
