The corruption is thick and quite troublesome to deal with, but it was quite easy for Elaina to deal with it to the point that even if it is quite a few layers on the ground, the Blessed Watering Can can easily wash it away like some kind of dust that has stuck on a surface.
Thanks to the enhancement that the Dragon Knight did to the watering can, it is clearing impurities left and right. Elaina even thinks that she took more time clearing the impurities of the minor World Tree compared to what she was doing now, which is more corrupted than the former, since it was the prime location and the center of all the corruption.
With the Dragon Knight removed and the source for the spread of corruption gone, Elaina is not worried that the cleansed areas would be corrupted again. She is more worried that she will not be able to finish the cleansing process much faster since she still has a large area she has yet to clear properly.
