Chen Daozi was truly heartbroken over the loss of the Heavenly Spirits. Though personally operating the process was the fastest way to improve one's artifact-refining skills, if a magic artifact was ruined, the loss of precious materials was one thing; losing Heavenly Spirits was far too costly.
An artifact refiner without sufficient foundational training in balancing the five elements, without ten years or more of assisting an artifact refiner, wanted to handle the work personally?
Even if he were Pang Daojun's son, he shouldn't be this arrogant. Did he really think Heavenly Spirits were cabbages, there for him to ruin as he pleased?
"It's fine. At worst, I'll just lose a few Heavenly Spirits."
Xu Yi's reply left Chen Daozi feeling stifled. Since Xu Yi himself didn't mind, Chen Daozi couldn't exactly grab his hands and force him to stop experimenting.
In the blink of an eye, four days and five nights passed.
Xu Yi stopped refining. Utterly exhausted, he stretched, then collapsed onto the ground. In his hand was a dagger gleaming with brilliant light. Even an ordinary person could see at a glance that it was clearly different from other daggers.
Chen Daozi had almost turned into a stone statue. He felt that over these past few days, he'd used up all the astonishment he'd accumulated over three lifetimes.
He couldn't imagine that Xu Yi had taken out more than eighty Heavenly Spirits in one go.
He couldn't imagine that Xu Yi's magical power had lasted all the way until now—seven hours, dozens of times longer than his own. And Xu Yi's corpse fire had burned for seven hours without showing the slightest sign of weakening.
Even more unbelievable was Xu Yi's talent for artifact refinement. From his third attempt onward, he had lasted longer than Chen Daozi.
