If he cultivated the Dual System Virtue Technique while also practicing a body-tempering technique and possessed enough power of virtue, he could achieve cross-realm cultivation.
As long as he had sufficient merit and a robust body, cultivating the sixth level of the Dual System Virtue Technique at the Fifth Stage Realm was theoretically feasible.
In the present world:
Song Shuhang's main body began to operate the Dual System Virtue Technique and once again commenced high-speed cultivation. This time, the driver was Fairy @#%×.
Among the myriad worlds, Song Shuhang was the least lacking in 'power of virtue.' His physique, primordial spirit, mental energy, and spiritual energy had all reached the level of a Ninth Stage Tribulation Transcender. Cultivating the Dual System Virtue Technique would yield twice the results with half the effort.
