Bab 442: Chapter 277: The First Pill Tribulation, Qi of Creation_2

"No wonder becoming a fourth-stage Pill Master requires one to be a Nascent Soul Cultivator."

"This fourth-order spiritual medicine, if judged solely by the divine sense of a Golden Core Master, cannot detect the impurities in it."

"Only when one has a divine sense at the Nascent Soul level can they perceive the impurities in a fourth-order spiritual medicine."

Zhou Sui exclaimed in astonishment.

When his divine sense power entered these fourth-order spiritual medicines, he immediately sensed a lot of impurities deep inside them.

The reason he could sense this was solely because his divine sense power is now comparable to that of a cultivator in the late Nascent Soul stage.

If his divine sense were just at the Golden Core Realm, then he certainly wouldn't be able to perceive this.

Therefore, the impurities in the fourth-order spiritual medicine cannot be eliminated.

Hence, the concoction of fourth-order pills would inevitably fail.
