Lin Wu ended up waiting near the grotto for about three days before he finally sensed something.
"Oh? It's changing." Lin Wu was woken up from his cultivation as some spirit Qi fluctuations reached him.
He looked at the location where the grotto was supposedly located and saw the air cracking.
~flicker~
"Hmm, so that's were it exactly is." Lin Wu muttered as he watched it open.
The cracks kept on expanding until finally a three meter wide hole was created. Nothing could be seen behind it other than just darkness. From this very hole appeared an old man.
"Yun Bai," Lin Wu called out.
Yun Bai who had just stepped out of the grotto was alarmed, having heard someone call his name. But in the next instant, he found the familiar presence.
"You're here?" Yun Bai questioned.
"I couldn't contact you, the communication jade slip didn't work. Thus I had no option but to wait here." Lin Wu answered once Yun Bai came to stand in front of him.
"Did something happen?" Yun Bai questioned.
