Phoenix Woman had always been extremely cautious on the Upper Ice Field, but now she finally showed a trace of boldness.
"Quick, let's go over and take a look!" she said excitedly.
Luo Zheng, on the other hand, grew cautious at this moment. "Wait. There are still some chunks of ice above that haven't fallen. It won't be fun getting crushed by them."
No sooner had he finished speaking than another huge block of transparent ice plummeted from above. With a resounding crash, it smashed a massive hole in the ice field.
The three of them waited in the distance for a while longer. Only after no more ice fell did they slowly approach.
The door outlined by the light remained closed.
Fearing that the metal box was as cold as the Cold Prison and impossible to approach, Phoenix Woman released a strand of Golden Crow Divine Fire.
The Golden Crow Divine Fire scorched the metal box. It did not go out immediately, but burned for a while like an ordinary flame before quietly vanishing.
"There's nothing wrong with the metal box itself, but how do we get inside?" Phoenix Woman said, shaking her head.

"What can fit into this indentation?" Phoenix Woman asked, puzzled.

"I might know,"
