The scene inside the Star Refining Furnace appeared before his eyes.
At the bottom of the furnace, a small pile of black ash scattered.
The first attempt at alchemy, failed.
As expected, Zhou Leng opened the Star Refining Furnace, a burnt smell wafting out.
He took out the residue, examined it carefully, and then reflected on the process, thinking through each step.
Then, he repeatedly put the materials for the Dragon and Tiger Pill into it.
Again and again, he failed.
With continuous practice, and the aid of alchemy books from high-level civilizations, Zhou Leng's experiences with Star Refining techniques progressed by leaps and bounds.
On the eleventh completion, he opened the furnace lid, and a faint medicinal aroma wafted out.
Looking down, a small pile of grey-white powder lay at the bottom of the furnace.
Zhou Leng wore a faint smile.
