After confirming with Elder Bai that there were no people around the outskirts of the Heavenly Origin Secret Realm, Ye Feng teleported Xiao Chuanqi and Sima Zhantian out of the Heavenly Origin Secret Realm.
Elder Bai could detect any activities within two kilometers outside the Heavenly Origin Secret Realm, and nothing could escape his scrutiny within that range.
It was necessary to scout first because opening the Gate of Whirlpool for the teleportation might be discovered by others. If they were spotted while opening the Gate of Whirlpool, those being teleported out of the Heavenly Origin Secret Realm would definitely be surrounded. It was not the time when the Heavenly Origin Secret Realm was officially open.
