The gray-robed Grand Elder finally spoke, his voice old but carrying an insight that pierced to the heart of the matter. "To force open a stable passage, our initial estimates suggest that at least ten True Saint Realm experts must expend their origins and strike together at the weakest point of the Space Barrier. Only then might they tear open a breach that can be sustained, with the aid of an ancient, world-breaking formation. That is the first difficulty.

Third, the passage itself would need layers of identification restrictions and protective formations to prevent anyone from exploiting the opening. Fourth, any living being traveling through it would have to endure the tempering and suppression of the laws. The higher their cultivation, the stronger the suppression and the greater the risk of backlash."
He laid out four core challenges in one breath, each enough to daunt any ordinary power. Ten True Saints! Innate Spiritual Treasures containing complete spatial laws!
