Ye Chong mixed in all kinds of chemicals into the alchemy test tube. The chemicals in the test tube changed colors from brown to purple, from purple to red, red to yellow, then to green, and finally to a very faint blue. When Ye Chong added the final ingredient into the test tube, the liquid inside became clear as water.
He heated the chemical slowly, evaporating the liquid until a small amount of powder was left in the test tube. Ye Chong carefully collected the powder, chewing a cloverfall leave that he bought specially for the work he did. However, work was not finished yet. Ye Chong went to another alchemy test tube. This one was filled with a black, sticky fluid that was bubbling.
When the black, sticky fluid was no longer bubbling, Ye Chong carefully poured out the black liquid inside. Once it was out, the black liquid looked like a rubbery solid.
Ye Chong was highly focused by now. His slender fingers moved deftly, applying just enough force for everything he did.
