Earth was truly too minuscule compared to the vast and boundless Cultivation World. If the Cultivation World were the expansive Par Ocean, then Earth would merely be a small puddle.
As for Tang Yi, who in his previous life had reached the level of Immortal Venerable, able to contend with the Immortal Emperor, the planet Earth, this puddle, was already beginning to restrain him!
Just lifting his gaze to the high heavens tens of thousands of meters above, with Tang Yi's current strength, he was still unable to break through. After all, to penetrate that thick layer of atmosphere was something that probably not even an ordinary cultivator at the Nascent Soul Stage could achieve.
And beyond that atmospheric layer lay the completely vacuumed, vast cosmos. To traverse the void of space by merely relying on one's physical body, one needed to have at least attained the Cultivation of Tribulation Transcendence Stage.
