The Soul Reaper turned around before disappearing from the place he killed the Essence Gods.
Once he finished his job, he only cared about the Heaven academy. He knew that he would need to travel to improve himself, so he wanted to spend as much time as he could with the academy.
Due to the presence of those Essence Gods, he hadn't had a proper training journey for a long time, so he was planning to have one as soon as possible.
After all, strength was what truly mattered. Without strength, he wouldn't be able to protect the Heaven Academy nor all the innocent people from those that delight in the suffering of others.
If it hadn't been because those three Essence Gods were too strong, they would have ruled the planet for so long. However, the weak couldn't argue. If the weak argued, they would just die in the best situation.
