The purification formation that Riya set up not long ago could only work in a small area, which is why it was suitable to make in the well.
But if Riya had to make a purification formation that covered the entire farm, then Riya had to say that she couldn't do it. It was more like, she could make it but it would cost a lot of magic cores.
For the current City A Base, it was not cost effective.
There were not that many magic beasts around at rank 1 or above…
"Wait, how many magic cores can you spare each month?" Riya asked. If she could use quite a lot of magic cores, then she could make it.
"Each month?" Samuel repeated and then replied, "I'm not sure how many magic cores that we can obtain each month but there should be at least 100 magic cores each month of various elements."
For the well, they had to separate the non elemental magic core, so it was impossible for them to use these magic cores.
