This fire-element immortal crystal ore vein appeared to stretch for more than ten thousand li, but in truth, it was not a material entity. Rather, it was a wondrous existence somewhere between immortal crystals and immortal spiritual dao essence. Otherwise, even though Lu Xiaotian had advanced to the Heavenly Immortal realm and the entrance to the Green Fruit Barrier was more spacious than before, it still would not have been able to accommodate so many things passing through and entering the barrier at once.
