It seems I'll still have to rely on those two Mara Banners to convert third-tier qi and blood to open this third Brahma aperture, Qing Chen mused inwardly.
It's also time to advance the Po Jun Banner into a low-grade magic treasure. But the qi and blood this secret technique requires are far beyond what a single high-grade second-tier island can supply.

Within his secluded cultivation chamber, Qing Chen underwent hundreds of days and nights of arduous
