Yun Bai brought Lin Wu to the entrance of the grotto and the two of them stopped there.
The old fox made a few hand seals before runes appeared in front of him that went and merged into the hidden formation array.
~shua~
Once that happened, the formation array responded appropriately and a hole opened up. But the hole was only big enough for Yun Bai to pass through.
"Hang on, the default is set to just this much. I've never actually had to open it all the way through before." Yun Bai said, as he made a few more runes and changed the settings of the formation array.
~flicker~
The formations lightly flickered like electrical static before finally starting to move. The hole started to expand until finally it was big enough to let Lin Wu pass through it.
"Enter." Yun Bai said and Lin Wu obliged.
Tim followed behind Lin Wu, his head looking at everything.
~shua~
