Capítulo 1878: Crystal

"What was it?" Zhou Wen hurriedly asked.

"I'm not too sure what it was. I've also asked your grandfather. He said that it was a round crystal. When he went to seek help from my father-in-law, it was taken away for research. He didn't return it to him," Zhou Lingfeng said after some thought.

"A round crystal? Was it spherical or circular?" Zhou Wen's expression immediately turned odd.

"I remember your grandfather said it was circular. He gestured back then. It didn't look very big," Zhou Lingfeng said as he thought.

Zhou Wen hurriedly rummaged through his things when he heard that. He remembered that there had indeed been such an item before.

Back then, he had found a small metal slab in the temple in Zhuolu. The small metal slab was very similar to the large metal slab that chained Earth's Companion Beast. Zhou Wen had used the passcode left behind by the former principal to open the small metal slab.
