Fifteen days; five days more than Fang Lin had anticipated.
It took a full half-month for Fang Lin and Liu Zhou to finally bring the refinement of True Essence Golden Body Pills to its conclusion. Before the sun rose on the sixteenth day, the True Essence Golden Body Pills were finally completed.
At the moment the pills were finished, Liu Zhou was utterly exhausted, nearly coughing up blood.
Though Fang Lin did not personally take action, these half-months drained him considerably; if he had refined the pills himself, he wouldn't have felt so fatigued.
After all, Fang Lin not only needed to guide Liu Zhou constantly but also had to worry about whether Liu Zhou would make mistakes, even thinking ahead about how to remedy any errors Liu Zhou might make.
