To be honest, after feeling on the edge of the blade over the supposition that something might go wrong with Sarina and Kana's awakening, Aster was feeling a bit tired, but there is a lot of things in his pending list and he can't just laze around the whole day.
Earlier when he refined the materials with Rigel's flames, he got to see how strong the flames had become due to the advance in his soul cultivation, but he still needed a more practical measurement.
This one of the problems of his cultivation realm not reflecting his actual strength, a way to precisely measure battle prowess didn't exist, besides of course fighting with others, once you reached the point where you found the opponent to be on equal standing that was the answer.
Luckily for Aster, he had a parade of beauties of different levels right here, so he just needed to ask them to lend him a hand to see how far has he progressed.
'Mm, the training room should be able to handle it', thought Aster.
