Trap?

The cracks on the gates of the Grotto Heaven started enlarging at a rate visible to naked eye. Everyone's attention turned towards the gates and they all eyed it with both anticipation and dread.

The moment of truth was here…

The lunatics from the Heavenly Demon Sect haven't done anything so far. But, no one trusted them to act peacefully once the gates closed. After all, if they wanted to be peaceful, why would they come with such a lineup?

So, everyone was naturally worried about them. 

Grotto Heavens were a unique existence in the cultivation world. They were independent spaces created by powerful cultivators. When their restrictions are broken and they are opened, there would be a small-scale disturbance in the surrounding lands.
