Emperor Summer and Drifter created techniques based on their Dao of Void that had reached grand perfection. Just by relying on the profound mysteries at the Primal Chaos Realm, they were able to attain the effects of 'pinnacle of void-ification'! As for how complex it was on cultivating them? They did not care. It was not easy just creating the techniques, and strictly speaking, Xue Ying referred to the Destruction Devil 'General Mo Gu's scaled-armor mystical inscriptions to come out with the technique.
The mysterious inscriptions on that scaled-armor had been naturally formed from the Origin World during the process of producing Destruction Devils. It could be said that they were created under the 'Supreme Law'.
Even though Emperor Summer and Drifter were powerful, compared to the natural phenomenon of the Supreme Law, they were still lacking. In terms of conciseness and ingenuity, they lacked that bit!
