Three years later.
Yuan Kingdom, Eternal Spring Mountain, an alchemy chamber.
Liu Yu sat cross-legged, his expression intent and his mind utterly focused, slowly forming hand seals with both hands.
Not far before him, the Mystic Yellow Cauldron trembled slightly. Pill Flame blazed within its fire ports, releasing scorching heat.
The temperature in the alchemy chamber had risen by dozens of degrees, and even the faint currents of air were searing hot.
Had the chamber not been specially constructed, it would have been destroyed long ago.
His grave expression and the trembling cauldron both showed that the refinement had reached a critical moment. The slightest carelessness could send all his efforts down the drain!
His powerful divine sense spread outward. Liu Yu constantly monitored the movements within the cauldron, striving to avoid even the smallest error.
He observed every minute change within it, skillfully controlling the entire process with the alchemy arts honed through countless attempts.
The Pill Flame in the fire ports dwindled, and the temperature fell slightly. As time passed, a medicinal fragrance gradually filled the air.
Almost time.
The thought flashed through Liu Yu's mind.
His wealth of alchemy experience told him that the best moment for the final step—Cauldron Opening—was approaching.
Although this refinement was about to end, Liu Yu's expression did not change in the slightest.
The more critical the moment, the easier it was to make a mistake. He had suffered plenty over this final step.
Now, he could face it calmly.
After all, even if he failed, he would have countless chances to try again.
"Open!"
Another two or three breaths passed. Liu Yu changed his hand seal, and the golden-red Pill Flame in the fire ports abruptly went out.
At the same time, the lid of the Mystic Yellow Cauldron suddenly rose.
