Every Eighth Grade Spiritual Medicine's level actually matches that of a Mahayana Cultivator.
They inherently contain traces of Law Rhymes within them.
However, ordinary cultivators couldn't detect them at all.
The top Pill Masters, utilizing the Soul Power, could induce the Law Rhymes contained within the Eighth Grade Spiritual Medicine and integrate them into the Pills.
However, achieving this was incredibly difficult.
But it wasn't impossible.
As long as the Soul Power was sufficiently strong and sensitive, it could inevitably be done.
Zhou Sui met these conditions exactly.
Firstly, his Soul Power had long been stronger than that of a regular Mahayana Cultivator, and secondly, he had cultivated the Seven Apertures Spirit Secret, consolidated his Heart Eyes, and possessed the Power of the Heart Eyes.
Such power of the Heart Eyes was infinitely mystical, capable of discerning deeper mysteries of the world.
It also included the mysteries of the Heaven and Earth Laws.
