Heretics

Damn it, back then, after fighting tooth and nail and wearing himself hoarse, he'd managed to extort just over seventy Heavenly Spirit Stones from the Purgatory Devil King. Who would've thought that after such a small battle, he'd reap a haul like this?

Without those hundred years, even if Lei Dong had cultivated constantly with Top Grade Spirit Stones and top-grade pills, his aptitude would never have been enough to reach Nascent Soul High-tier in a mere few decades.
