1000 The Second Experience

Shortly after realizing he had entered the Astral Soul Realm, Leon understood what he had to do right away. 

"According to the last experience, there's a fixed time before the realm guardian appears and banishes me from the Astral Soul Realm. Thus, before that happens, I only have a limited time to absorb the pure soul energy of this place."

Leon recalled. 

Nevertheless, he didn't feel much pure soul energy in his present location. He had to reach the surface quickly and absorb the pure soul energy in a richer area.

Once Leon understood that, he immediately left the ice warehouse. 

However, the entrance to the underground space was already sealed the last time they left the Radiant Heaven Realmship.

Furthermore, Leon couldn't contact the realmship to teleport him to the surface in his astral form. They weren't in the same dimension.
