After all, the Yun Family's location was near the Central Domain of the Dragon Martial Continent, where a catastrophe had already fully erupted.

Astonishing lights couldn't help but burst forth from Su Han's eyes.
These Blood Crystals didn't have any special method of usage, you just had to swallow them, and they would immediately transform into lifespan and vital energy.

That swallowing them was useless!
