Ryu didn't know how long passed, but his mother did eventually let him go. Finally, he was able to take out what he had prepared.
He knew that he would be returning to his mother's side, so how could he not remember her ailments?
Himari had made it quite far into the Sky God Realms, but that didn't mean that Ryu was helpless, especially since he had the treasures of the Frost Clan and the little woman by his side.
In the years he was away, the little woman managed to make it to the Omniscient Sky God Realm and was already striving for the Dao Lord Realm. It turned out the environment of the blackhole was a tonic to her rather than being toxic. In fact, it was also in part thanks to her that he was able to succeed in the end.
While it made him curious about who she really was, he was far more interested in how she could help his mother.
