The Seven Realms
-This would seem like more to you if you had Ascended earlier. You should be thankful that Ascended Creatures killed in the Celestial Planes are worth a million and not the previous ten thousand.
-Only creatures in the Initial Deity Realm and above will grant you Ascension Points. The Sound Mouse was at the peak of the Ascension Realm, but a few more years of Cultivation and it would have broken through. Your luck is truly horrible.
The System's words made William calm down a little. He had to admit that the System made perfect sense. It was only a thousand Ascension Realm Magical Beasts to kill; as long as he chose his targets wisely it wouldn't be a huge issue.
What's the gap between the bottom of the Ascension Realm and the peak? William paid only a few thousand for an answer.
