The place star beasts lived at was boundless. Ye Mo and shadowless fought for a few months and flew for a few month. Eventually, Ye Mo just kept killing star beasts while cultivating his god art and refining his immortal essence and spirit sense.
As for cultivation level, Ye Mo didn't plan to cultivate it. The main problem was that he didn't have enough cultivation resources. In this place, there was only star beasts, there would occasionally be some high level forgery material but no immortal range and immortal spirit herb.
Ye Mo's main cultivation resources were from Chang Tian immortal monarch. Ye Mo got a top grade immortal range and two middle grade immortal ranges from there, there was also 1 billion immortal crystals. This really wasn't many immortal crystals for an immortal monarch but he had large amounts of immortal spirit herb and forgery materials. These things were more important than immortal crystals for Ye Mo.
