The Death God appeared firstly to protect Han Fei's original body, and secondly to attract the hidden dominators of the Eternal Race.
In fact, after this step, Han Fei could already destroy the Eternal Race. At this moment, he just needed to take the Creation Star Compass to the Path of No Return and throw it into the Path of No Return.
However, Han Fei couldn't do that, because he hadn't found the Demon Purification Pot's vine. Since it wasn't on the Bloodline Divine Tree, it could only be in the hands of a certain dominator.
If he really threw the Creation Star Compass into the Path of No Return, the Demon Purification Pot might never be able to be repaired, and the tenth fruit might never be used by him.
