A thought suddenly flashed through Qin Li's mind like a bolt of lightning, startling him. He had never heard Ji Yuyan's theory before, but he had to admit that what she said seemed to make some sense!
Before reaching the Thunder Tribulation Realm, it was naturally hard to imagine just how powerful it was. But now that Qin Li had broken through to this level, he understood just how terrifying a single Thunder Tribulation Martial Artist could be.
If five thousand to ten thousand Thunder Tribulation Martial Artists were to attack simultaneously from the sky, they could easily obliterate a small kingdom with an area of several thousand square li in an instant. But if those same people were to try and build a world that covered the entire Celestial Essence Continent, an area of several million square li, that would be incredibly difficult. It would be an almost impossible task!
