"Trouble."
That thought emerged in Han Yi's heart.
The Taoist ancestors and Immortal Venerates present all felt a deep gravity in their hearts as well.
If it were just connectivity between the Nine Realms, they would not be too worried. Kunlun and Penglai practiced the Immortal Path, Eternal Life practiced the Witchcraft Tao; these three worlds had interactions before, and this act was merely like establishing a pathway connecting two realms.
As for the Taoist Ancestor-level Mysterious Demons of the Mysterious Demon Realm, they had never left their own world. If only Immortal Venerate-level Mysterious Demons came forth, the Taoist ancestors could seal them with a wave of their hands and throw them back into the Mysterious Demon Realm.
Handling the Savage Wilderness Realm was also not difficult. They only needed to set up an Immortal Array near the entrance to block the savage beasts that might run out.
