Everything had turned out exactly as he had hoped and it seemed his time in the Underground Coves was coming to an end, as the demonic master's arrival was around the corner.
He could see from his status that Sub-Dimensions were ranked in realms and not sub-ranks, and for him to upgrade it to the next realm, he needed to surpass the Mortal Cultivation Realm.
He was currently at the Golden Mortal Rank, all that was left of the Mortal Realm was the Mortal King Rank, then he would breakthrough into the next realm.
Lex knew that wasn't something that would happen in a short amount of time and he would need at least a year to break through the Mortal Realm, so he wouldn't be able to break through his Portable Sub-Dimension to the next rank any time soon.
However, he could still increase the size and quality of the Portable Sub-Dimension until then as it would need to hold at least 500 fox beasts.
