Meng Chuan was somewhat astonished when he heard that.
The reason why he had forcefully rejected the demand was that he was prepared to fall out with Fiend Eye. Once he did so, his Essence Soul avatar in Earth Cloud Mystic Realm would teleport everyone from Archean Eon Realm back to their homeworld. Meng Chuan had made arrangements for his grandson, Meng Yu—who had long reached the Imperial Lord realm. Furthermore, it wouldn't be easy for Fiend Eye to find Earth Cloud Mystic Realm without the karmic connection as long as he left Earth Cloud Mystic Realm.
Every mystic realm was created by an Eighth Tribulation Eminence. Seventh Tribulation Eminences needed luck to find a mystic realm. Many mystic realms in the River of Spacetime still remained ownerless. Even if people knew that they were in a certain region, they couldn't find them.
Furthermore, Earth Cloud Mystic Realm was hidden by Ancestral Master Archean Eon's array.
