He needed to divide them into two portions: most would be refined into "Advanced Enhancement Potions" for demon hunters, capable of rapidly restoring stamina, healing severe injuries, and greatly improving physical attributes and energy resistance for a short time.
A smaller portion required more complex processing to be refined into more potent "Core Evolution Potions," capable of triggering an essential transformation.
During the process, a few crystal cores occasionally underwent violent reactions due to minute residual instability or energy conflicts within them. Their colors abruptly turned scarlet or deathly pale, on the verge of exploding.
Whenever that happened, Wu Heng could sense it 0.01 seconds in advance. A gray-black beam that combined Pestilence Corrosion, capable of destroying unstable structures, and Deathly Extinction, capable of calming berserk energy, would precisely strike the crystal core, forcibly suppressing it and guiding it back on track.
His mental power was like the finest woven net, enveloping every crystal core as he carried out tens of thousands of simultaneous micro-adjustments.
The burden would have been unimaginable for anyone else, yet his breathing remained steady. Only his face was somewhat paler than usual.
When the last trace of restless energy within the case subsided and every crystal core emitted a perfectly harmonious dark-gold luster, Wu Heng opened his eyes.
The interior structure of the case had changed.
On the left, ten thousand sealed transparent crystal tubes were neatly arranged. Golden liquid shimmered faintly within them—these were the Advanced Enhancement Potions.
On the right were 3,200 slightly thicker dark-gold metal tubes, their surfaces etched with more intricate runes. Every one of them was a Core Evolution Potion.
He waved a hand and closed the lid, casting several sealing incantations. The metal case turned into a streak of light and vanished into the pocket of his trench coat.
