"Can this opening be sealed?"

"What about just destroying it directly?"
"Hermit Cai, don't keep doing things this way. Even if you destroy this one, others will appear. With the Spiritual Qi Resurgence, a Nether Soul Realm is bound to show up.

The Nether Soul Realm itself isn't really a problem, it's only certain nether souls that can be an issue. Better to guide it than to block it completely."
