Inside Mar-Dule's body, a golden orb appeared in the center of his chest. Between the white orb and this golden orb was a golden path that connected them.
The abundance of Mar-Dule's Aether Energy was flowing into the white orb and traveling this path upwards to the golden orb.
This golden orb was the Energy Core one would open after entering the Spiritual Realm. This was where the Aether Energy one gathered in the Spiritual Realm is stored.
Bang!
The general leading his battalion crashed into the second gate. The second gate opened only a sliver, allowing him to slip through.
In the outside world, some of the chains around Mar-Dule's illusory Spiritual Palace shattered before the double doors opened a sliver.
However, as the battalion surged through the second gate the double doors slowly started to open wider and wider.
