"How is my sister?" Yu Caixing asked.
Zhang Lingshan said, "Her condition is good. If you're worried, you can go over and take a look."
"No need. I doubt you'd dare lie to me."
Yu Caixing snorted, then said, "I'm going to start the first stage of mixing the solution now. Keep your eyes wide open and watch carefully. I won't demonstrate it a second time."
"Mm. Begin."
Zhang Lingshan nodded.
Yu Caixing's hands rapidly formed seals. Whether she was worried Zhang Lingshan would see too clearly, or whether her refining technique was simply this fast to begin with, her hands blurred through the air, producing streaks of multicolored flame light that merged into the mixed molten solution.
In less than a moment, the mixed molten solution had completely stabilized. All they had to do was keep it that way.
"Did you see it clearly?"
Yu Caixing said, "Then start your own work. Keep refining for me."
"All right."
Zhang Lingshan wasted no words and continued refining First-Grade materials.
Back when he had refined this Spirit Spring Sword with Pei Daoming, it had taken a full three months.
But that was because he had been unskilled at the time, and both the intensity of his flame and his mental strength had been relatively poor, far inferior to his current refining speed.
Now, it did not need that long. At least for Zhang Lingshan to refine these materials, it would take less than ten days.
Next, it depended on Yu Caixing's ability.
If she condensed quickly, it would show her skill was high. After Zhang Lingshan recorded her techniques, he could also greatly improve his own artifact-refining level.
If she condensed slowly, Zhang Lingshan could observe her artifact-refining techniques in even greater detail, and likewise improve his own artifact-refining level.
