"What's that?" Liu Yun looked at the thing that came out of the cave with a look of surprise.
"How would I know what it is!" Zhou Wen couldn't tell what it was either.
The thing that came out of the cave didn't look like a living creature. From the exposed parts outside the cave, it looked like a metal container.
As only a portion of it was exposed, its entire body couldn't be seen. It looked like a metal container with four sides. There were many strange and mysterious patterns engraved on it, making it look ancient.
The metal container was still squeezing out because it was slightly bigger than the cave. With every movement, the metal outer wall emitted an ear-piercing screech as it rubbed against the mountain wall. It was the sound Zhou Wen and Liu Yun had heard previously.
Clang!
