Divine Soul turning solid, not only enhances the strength of the Divine Soul, but it is also an essential process for the Day Trip of the Divine Soul.
Xu Qing is exploring combat to grasp the usage of the Yaksha King.
"No matter what, the Yaksha King is conceived through visualization and is limited by my own Night Wander Realm. Its attack power can still only be manifested through illusion. However, once I get used to manipulating it, even as it grows stronger, my control over it will remain undiminished."
Xu Qing discovered that the Yaksha King is similar to a malicious dog: it can get out of control but can also be tamed.
As long as he continues to train it, even if it gets slightly stronger than his Divine Soul, he can still keep it under control.
Such training is also a process of constantly subduing one's evil thoughts and reining in a restless mind. As the Divine Soul becomes firmer, it also grows stronger.
