He was refining the impurities within the iron ore.
The reason he had bought this batch of iron ore was because he had noticed its unique qualities.
Although this batch of iron ore was not top-grade, it contained exceptionally abundant Spiritual Energy and was the ideal material for forging weapons.
Li Changsheng was already at the half-step Foundation Establishment Peak, not far from condensing spell runes.
What he lacked now was precisely this Spiritual Energy, so he intended to buy this batch of iron ore to improve his cultivation.
Very soon, Li Changsheng absorbed the impurities from this batch of iron ore.
Though the iron ore contained quite a bit of Spiritual Energy, Li Changsheng was already at Foundation Establishment Peak, so he did not need much.
"Phew..."
Li Changsheng let out a deep breath and opened his eyes.
At that moment, delight appeared on his face, and a faint smile curled across his lips.
"It seems my luck is truly good. This batch of iron ore really did not disappoint me. This way, I can use it to refine Spiritual Energy." Li Changsheng muttered to himself.
The purity of this batch of iron ore had reached six out of ten, making it even purer than Li Changsheng had expected.
"Not bad, not bad. This batch of iron ore..."
After saying that, Li Changsheng turned his gaze toward the other end of the iron ore. There were three fist-sized metal ores there, emitting intense metallic auras.
He had spent ten thousand taels of gold to buy these three ores. Now, he planned to spend the remaining ten thousand taels on them, successfully refining either a weapon or a pill.
His cultivation had already reached Foundation Establishment Peak. There was practically no hope of breaking through to the Golden Elixir Stage.
