Such an advantage, combined with his own powerful soul ability, could become a formidable method.
That's why, when Zhou Yan proposed his views on the Tao, he had already conceived this idea.
If he could not succeed, then it would merely be a bit of enlightenment, with no loss to himself.
If he could succeed, then he would obtain a method to further refine and better utilize his soul ability.
It was an all-gain, no-loss situation, something Zhou Yan was quite willing to happen.
The key question was whether Jia Yongheng cared about this so-called "Original Dao" or not.
This was fishing strategy, the advice to Si Yuan Cultivator and Yan Ran Cultivator was all a guise; the true aim lay in the cultivation technique for the Body of Destiny.
That was Zhou Yan's calculation, but even with such thoughts, he wouldn't take the initiative to bring it up, instead waiting for Jia Yongheng to express his doubts, and then enticing him further.
