The Spirit King wanted to cry.
Just now, he was clearly close to shattering the energy barrier of the Great Emperor's City!
He could even severely injure the Heavenly Tree.
But why?
In that instant, the originally shaky energy barrier seemed to have suddenly been reforged.
As the light circulated, no matter how hard he attacked, he could not shake it at all.
"How did this happen?!"
The Spirit King gritted his teeth in hatred.
However, his vision was blocked by the branches and leaves of the Heavenly Tree. He could not see what was happening in the Great Emperor's City at all.
In his body, the power from the Heart of the Netherworld was already showing signs of dissipating.
Clearly, it could not last long.
The Spirit King's expression was extremely ugly.
He quickly thought of a way.
"Do I have to consume another quarter of the Heart of the Netherworld?"
