A few Puchi sounds rang out, only to see the medicinal liquid roll in the flame, the impurities inside were refined into ash, and finally floated out of the medicinal cauldron.
Li Tian sat on the ground with his legs crossed. He kept pushing his palms out, causing the medicinal cauldron to spin rapidly. In the end, it actually formed a whirlwind.
"Haha, what's he doing? he's playing tricks at such a critical time. Is he trying to make us happy?"
One of the apprentices laughed out loud, and the others followed suit, laughing at Li Tian.
Even elder Liu and the others shook their heads in disappointment. The most important thing in alchemy was to have a calm heart. If he were to do this, he would not even be able to complete the pill condensation stage.
But very soon, the expressions on their faces froze, because the content of the impurities was gradually decreasing, and finally dropped to less than five percent!
