While the spectators were confused, Shen Xu began his work.
First, he purified his materials, one at a time.
Although he pre-emptively soaked them in spiritual water to remove the impurities, Shen Xu was not complacent.
After the purification, he began to melt and extract the material essence.
An hour later, Shen Xu had eight bottles in front of him.
'The purification, melting, and extraction went well.' He thought but didn't dare to be self-satisfied.
After all, what he had already done was the easiest part of his refining process.
'Next is the true refining.' He thought, and a red fire appeared on the palm of his right hand.
Soon after, Shen Xu adjusted the flame and moved the fire to below the refining furnace.
Following that, Shen Xu cleaned the furnace and allowed it to dry.
After it dried, he waited for it to heat to the appropriate temperature before pouring in the essence of natural cotton.
