Capítulo 2514: Why Have You Kept Him In A Net?

The barrier was actually set up for Gu Xijiu to hide in if Yun Yanli ever managed to find a way past the wizardry barrier. It would also be a good place to hide Di Fuyi's statue if anything ever happened. 

She certainly did not expect to experience a catastrophe at the same time that Yun Yanli broke into the valley. It made her a live target, and she knew that she could not hide. Therefore, before she experienced the catastrophe, she buried the jade statue into the wizardry barrier. 

Kun Xueyi went into the lake with Guardian Jin in the middle of the battle. He actually hid inside the wizardry barrier as well. Yun Yanli thought that the two persons had run away, so he did not chase after them.
