Not long after, the expansion of the Cave Heaven World began to slow down until it came to a halt at the size of two hundred thousand kilometers.
As the expansion of the Cave Heaven World ceased, Jiang Yuan's aura, which had been surging wildly, also started to subside.
Another moment passed.
The breakthrough finally ended, and Jiang Yuan took a look inside himself.
Now, the Cave Heaven World was approximately two hundred thousand kilometers in size.
Sweeping his gaze over his own Cave Heaven World, Jiang Yuan couldn't help but marvel.
Such a massive Cave Heaven World could fit the diameter of about sixteen Blue Stars of his previous life from south to north.
This Cave Heaven World had now become incredibly vast.
But even with such a colossal world, the Cave Heaven World was still a quiet expanse of silence.
Even though it was filled with primeval wilderness and mountains and rivers.
Within the entire Cave Heaven World, there was no existence of any living beings.
