Celestial Level Arrays

'What is this?' Lin Mu didn't even know what he was gazing at.

It was just pitch black, as if there was nothing there. And it wasn't the normal darkness of the void either… it was different. 

It was… Blank.

~THUD~

And before Lin Mu could look at it any longer, the small portal threw out a High Grade Immortal Stone and disappeared.

"Any success?" Crown Prince Feng Shun asked.

"No." Lin Mu shook his head, his expression a bit confused. "This is strange, I cannot see anything there. It's just… Empty." 

"We are in a Celestial's Treasure, so there is a chance it is a Spatial Array at the Celestial level." Elder Hu reminded them.

"That is true." Ziran nodded. "If it is indeed something at the Celestial level, even Daoist Mu Lin won't be able to observe it." He knew just how far Celestials were from Immortals.
