Nine Heavens Divine Thunder had a formidable origin.
This thunder technique had been passed down from an Ancient Immortal Sect. It was obtained by West Sea Sect disciples during their exploration of the Nine Dragon Underground Palace. Divided into upper, middle, and lower parts, it corresponded to the three major realms of Purple Mansion, Golden Core, and Nascent Soul.
Nine Heavens Divine Thunder was supremely hard and supremely Yang, a pure Yang thunder technique restricted to male cultivators. It was also profound and vast, exceedingly difficult to master.
After obtaining Nine Heavens Divine Thunder, West Sea Sect had not listed it among the sect's true inheritance techniques. That was why Wang Chen could acquire it from the Library Pavilion; otherwise, given his current status, he would never have had access to such a superior spell.
This was also the breadth and bearing of the Mountain Sea Realm's foremost immortal sect. In any other small or mid-sized sect, the Nine Heavens Divine Lightning Method would absolutely have been an untransmitted secret, forbidden to all but the Sect Master's direct lineage.
Wang Chen had chosen this spell because Nine Heavens Divine Thunder and Five Suns Dry Thunder were both pure Yang thunder techniques, their lineages flowing from the same source. With Five Suns Dry Thunder at Great Perfection as his foundation, cultivating Nine Heavens Divine Thunder would surely yield twice the result with half the effort.
Moreover, Nine Heavens Divine Thunder possessed peerless might. It was a powerful spell that could serve as a trump card, perfectly fitting Wang Chen's needs.
It was just that with his Spiritual Root and comprehension, comprehending this superior thunder technique was undoubtedly somewhat beyond his reach.
Fortunately, Wang Chen had another reward.
