Refining an entire mountain of stone into gold, silver, copper, and iron would definitely transcend the category of shaping matter from existing forms, as for what it is...
Jin Guang had no clue.
All he knew was one thing... he reckoned he wouldn't be able to escape.
"Master, do you think this pill furnace is alright?" Song Yin asked.
Jin Guang was still in a daze when Song Yin's voice startled him, causing his body to jerk. The corner of his mouth twitched as if he was forcibly controlling his facial muscles to smile, revealing a very odd grin, "Good, good..."

It looked like he'd done well.
"With the Great Elixir Furnace, I can refine restorative elixirs for Master!" Song Yin exclaimed with excitement.
Jin Guang was still shaking when something suddenly dawned on him.
Right!
Medicinal herbs!
