"Why?"
Ye Fan had never thought about this question, but now, hearing Chu Ji ask it, he couldn't help but feel curious.
"Since the end of the last century, the concentration of Heaven and Earth Primordial Qi on Earth has suddenly increased, approximately tenfold!" Chu Ji revealed the mystery.
"What... what?" Ye Fan was startled and blurted out, "How could the Heaven and Earth Primordial Qi suddenly become denser?"
"I don't know."
Chu Ji shook her head and continued, "But because the concentration of Heaven and Earth Primordial Qi has increased tenfold, cultivators' cultivation speed has also increased accordingly, giving rise to one martial arts genius after another and many experts! You should know, in the past, a supreme strongman of the Gang Qi Realm would only emerge every few hundred years!"
"Ding Dong—"
As Chu Ji finished speaking, before Ye Fan could recover from his astonishment, a crisp sound rang out, and the elevator doors slowly opened.
"Whew~"
