"Master, How will the quality of the pill be decided?" Tian Jian doubtfully asked.
"Quality is dependent on the level of impurities does a pill has." Qin Shun solemnly said and continued,
"Normal Level is 10-30 percent impurities free, Earth Level is 30-60 percent impurities free, Heaven Level is 60-90 percent impurities free, and Divine level is almost equal to 99.99% impurities free." Qin Shan explained.
"So, That's how it is, ah!" Tian Jian slowly said.
"Yes! In alchemy, every minute mistake will result in some impurities, so only with utmost perfection can one make divine pills, so those are so rare. In the market, Most of them are Earth Level pills, and Heaven Level pills are for exclusive customers, and sometimes they will appear in auctions." Qin Shun said sedately.
