"If I can increase my soul strength, maybe I can cultivate the third layer of the Great Sun Codex!" Ryan thought.
But increasing the strength of one's soul was very difficult.
For a Rank 7, the most direct way to increase the strength of the soul was to transform it into a divine soul, which would make the soul very powerful.
But then he would no longer count as a Rank 7, and there would be no way to reach for the Son of the Universe anymore.
That wouldn't work.
He had to increase the strength of his soul without transforming it.
Ryan recalled the memory inheritance of Lord Aurelian.
It seemed that Lord Aurelian's memory inheritance contained information about techniques for increasing the strength of the soul.
Soon, Ryan found the information about soul strength in the memory inheritance.
"Soul Training Technique!"
