At the back side of the third mountain peak…
Shi Mu sized-up the rock-cave in front of him. There was nothing outside the cave; apart from a small stone-house. Only black bare rocks could be seen everywhere; there wasn’t even a trace of any plant.
His figure moved up and down the rocky surface, and reached the entrance to the cave. Consequently, a heat wave came rushing out of the cave, and warmed-up Shi Mu’s body.
Then, a man wearing a black robe came out from the stone-house.
"Oh! It’s Senior Brother. Have you come to rent the Fire Room to concoct pills or refine some tools?" The black robed man came forward, and cupped his hands. He then asked with a smile.
Shi Mu turned his head, and looked towards him. He found that the person in front of him was one of the twenty newly appointed third-grade disciples. He nodded and replied, "I want to rent a fire room to concoct pills. I may refine some tools as well."
