Although the eighth line wasn't as obvious as the rest, it was there nonetheless. Hence, the pill was indeed an eighth-grade pill!
Lin Tianfeng almost thought that he was imagining things. He dazedly stared at the pill for a long time. "D-didn't you… say that you're a seventh-grade heavenly doctor?"
"I was indeed a seventh-grade heavenly doctor at the time, but I didn't say that I couldn't refine an eighth-grade pill. Hm, since I succeeded this time, then it's probably an eighth-grade pill…" said Chu Liuyue with a smile as she rubbed her chin in a thoughtful manner. To be honest, she was actually quite surprised herself, for the pill she wanted to refine was supposedly a superior seventh-grade pill. Maybe it's because the herbs used were all of superior quality, or perhaps it's because I refined it with the Heavenly Square Cauldron… In any case, the pill produced barely made it into the eighth grade. This is considered an unexpected surprise.
