Muku who had resigned to his fate told Mrs C every significant thing which happened to him.
From how he travelled through the Middle Zone to the outskirts. Then how he made his way up the food chain of the outskirts.
He didn't immediately let go of himself since there were R4s and R5s everywhere, even on the outskirts. So, with the help of Raya who was familiar with the outskirts. They looked for an area which was unlikely to have beasts beyond LR3.
After all, even on the outskirts, there were places with mana so thin that most beasts avoided them. Then there were areas like the desert in between the forest and the ocean on one side.
That place was also off limits. This was because it was full of large sandworms. The beasts ranged from Unranked to R6.
They had great senses and would know the moment any creature with a death wish steps onto their sand.
