章 229: Four Frozen Fairy is injured

Ye Chen took some medicinal plants and put them into the dual dragon cauldron, after Ye Chen put the medicinal plants into the dual dragon cauldro, n Ye Chen closed the dual dragon cauldron.

Ye Chen began to circulate the fire inside the dual dragon cauldron, the first stage was the purification process, this process was no less important because it would determine the level of purity of the pills that were made.

In this process one must be very careful that a little mistake in separating impurities in medicinal plants can result in failure to make pills.

Ye Chen must continue to maintain the temperature inside the dual dragon cauldron so that it is not too high or not too low, the temperature must be set as well as possible so as not to burn the medicinal plants in the dual dragon cauldron.
