The Recuperate Pearl, his own divine power foundation, and the push of the dragon breath to merge with his own dragon breath, these were all critical elements to help Qin Wushuang achieve the breakthrough.
Initially when Qin Wushuang broke into the Exquisite Mysterious Boundary Stage at the ordeal island of the Illusion Heavenly Lake, he had already begun to intentionally strengthen his comprehension of the Supreme Dao.
In this one year, Qin Wushuang spent a lot of time through meditation to comprehend the Supreme Dao.
Therefore, Qin Wushuang made sufficient enough homework to prepare his comprehension of the Supreme Dao.
As if he had the experience of the Supreme Dao before a dozen of previous generations of reincarnations, Qin Wushuang was incredibly familiar and natural during this breakthrough process.
Qin Wushuang knew that although the Supreme Dao Stage was high in the air, in fact it was only an extension to those stages from beneath.
