Therefore, cleaning it again must be done with the utmost caution, caution, and more caution.
Take this Secret Realm in front of us, for example, there are already 5 Vanguards inside with an average strength of over 40. If they indeed fail and forever become part of the Secret Realm, then re-entering to clean it up would require waiting for the Secret Realm to expand enough to fit a space of about 80 before daring to send in another Vanguard of that strength level.
After all, if the rescue operation fails again, it would mean the creation of an even "larger dead Secret Realm."
On the other hand, as it devours more and more powerful Vanguards, the situation inside will become increasingly dangerous and unpredictable, and the risk of mutation will soar exponentially.
And as it continues to evolve, it will become akin to a melanoma, spreading the barbarism of the Secret Realm to the entire world...
