The origin crystals here all contained fragments of abyssal rules, and looked rather different from the origin crystals outside.
This difference left Xu Changxing slightly uneasy.
Soon, however, his worries vanished.
These origin crystals could also be exchanged for system points.
To think abyssal demonic beasts stored origin crystals too!
This unexpected windfall made Xu Changxing's chest rise and fall slightly.
His gaze also drifted unconsciously toward the depths of the Abyss.
Before this, he had been searching for ways to gather origin crystals quickly.
Yet all those methods came at an enormous cost.
That was why he had chosen to slowly refine pills in exchange for origin crystals.
But this unexpected discovery had given Xu Changxing a shortcut whose cost did not seem quite so high.
The demonic beasts in the Abyss actually took the initiative to gather origin crystals!
He had merely slaughtered his way through the uppermost layer of the Abyss, yet had gained nearly fifty origin crystals in one go.
If he could fight his way into the depths of the Abyss, wouldn't he be able to get thousands of origin crystals with ease?
At this thought, a gleam involuntarily flashed in Xu Changxing's eyes.
But he merely entertained the thought and did not actually set out for the next layer of the Abyss.
He had only managed to kill Zhu Lu this time because he had been lucky.
Had Zhu Lu been at his peak, Xu Changxing could only have fled.
Yet the Lower-Layer Abyss contained demonic beasts even stronger than Zhu Lu.
Xu Changxing vaguely felt that Zhu Lu had very likely suffered those severe injuries by rashly entering the Lower-Layer Abyss.
Until his strength surpassed Zhu Lu at his peak, he had no intention of exploring the Lower-Layer Abyss for the time being.
