"It looks like all of you can go inside your inner world. After thinking about this, I came to this conclusion.
First of all, Saint Markus and the others are unable to go inside the inner world due to the restrictions of our planet.

Your spiritual energy system becomes solid, and also your foundation becomes connected with your energy system.
But when I decided to change the energy system, your foundation began to get damaged. Fortunately, it looks like your core. I will prevent that from happening by expelling spiritual energy.
Because of my spiritual energy, your core feels true spiritual energy. Because of this, your body automatically begins to expel all the other's spiritual energy and also pulls your consciousness into the inner world.
