Passing through an area where Demon Hounds spawned, some more advanced Demon Hyenas began to appear around them. They were slightly larger than Demon Hounds, their bodies covered in sharp Bone Spikes, and were Level 180 elite monsters. Their combat power was much stronger than regular Demon Hounds, but also offered several times more experiences.
When dealing with the Demon Hyenas, Nie Yan and the others were more cautious, continuing their fierce level grinding. The experience points steadily rose, and the pace was quite impressive.
It took Nie Yan four days to reach Level 141, six days to reach Level 142, and twelve days to reach Level 143. Twenty days passed by quickly, and their exploration of the Dark World had only just begun.
Nie Yan still couldn't find any trace of Mephisto. He glanced at his bag; the energy released by the Paternoster Warhammer grew increasingly powerful, with electric currents crackling and a rampant force that was terrifying.
