“What’s that?” Jade came over and took the box from Alex’s hand. “It’s pretty heavy. How could this tiny box weigh at least five hundred thousand kilograms? What’s inside it?”

The box was entirely black.

There were no patterns that indicated any mechanism on it, and after Alex had observed it for a while, he still couldn’t find any runes.

Most importantly, the box couldn’t be opened.

Jade took out the Martello Celio. “Let me take a hit at it and see if it’d open.”

Alex quickly stopped her.
