Sin Devourer
On the Grand Forest, the first, second and third layers have been completely explored by me so we traveled towards the fourth layer, pass the Slime Forest and the Water Shrine.
Talking about the Water Shrine, I've been keeping some contact with the Water Spirits. It seems that the dungeon did get purified and no monsters are appearing once again, except for some monsters from the outside that try to find refuge inside.
The Water Spirits are strong enough to at least scare these weaker monsters away without much effort.
After purifying the shrine, they began to purify the nearby forest. Increasing its flow of magic, increasing the vegetation growth, the clarity and quality of water and even the life of the monsters and animals.
