Thunder Pool Tesseract

Ding!

[Thunder Pool Tesseract: Yun Zhongzi captured the Spirits of the First Thunder and gathered them into this tesseract spiritual pool. No one is allowed to step foot in the area covered by the Thunder Pool Tesseract! Do you want to take it?]

"Yun Zhongzi… He is one of the greater deities of Chanism. I think it would be practically indestructible on earth since he crafted it personally!" Chen Xiaobei exclaimed excitedly as he regarded it carefully.

"Hmmm. 'No one is allowed to set foot in the area covered by the Thunder Pool Tesseract'? Might be good for defensive applications. Either way, I'm not too sure. Guess I should ask Monkey King about it first…" He mumbled and whipped out his cellphone.

Monkey King: A little busy here, so I'll cut to the chase. The Thunder Pool Tesseract is actually half-completed, but it can be used for protection. No enemies can set foot in the area it covered.
