Chapter 157 - He's-!

It seems that... We're mesmerized by the appearance of the Flower of Zeratria.

It's white five petals were glowing in a bright white color and its brightness of light were surrounding the entire arena with it. 

"Oh?" A system message then popped up in front of me. 

[Sky Island's Five Stage Trial Champion, win the trials held by the sky island. This is a generated event in the world of Pandir. By unlocking this achievement, one key will be added to your inventory.]

[Sky Island Champion Key]

Use this key to enter the sky island's second stage. Recommended level, Level 200 - Level 400.

What are these items? It seems... weird. I have never received any item like this. And the system says it's a generated event? Does that mean that this trial is set up by the gods? This is difficult to fully understand.
