Primordial Heavenly Sovereign wished to accept Jiang Ziya as his disciple, being valued by a Saint, how could Jiang Ziya refuse? He promptly agreed with delight.
Then, Jiang Ziya took the opportunity to ask his own questions and sought clarification from Primordial Heavenly Sovereign.
One can only say that a Saint is indeed a Saint. Faced with Jiang Ziya's inquiries, he didn't even think before directly saying, "This matter is simple for you, since practice requires aptitude, why not create a cultivation system that doesn't need aptitude? Thus, wouldn't the problem be solved?"
Primordial Heavenly Sovereign spoke simply, but he also knew that creating a new path was extremely difficult, something many Great Divine Transcendents were unable to achieve.
Therefore, his purpose in saying this was merely to dispel Jiang Ziya's obsession, to prevent him from being too fixated.
