The box is not big, two feet long, and about one foot wide and high.

This box alone looks like it is not an ordinary thing, exuding an indestructible aura. Jiang Xuan has never seen this kind of material before, and just by feeling, he feels that this is also an excellent material for the robbery realm.

"It's really luxurious, it's just a box for distributing rewards, but the material is many times better than my knife. My knife is the weapon of the patriarch of the Jiang clan. The Jiang clan has produced several robbery realms in history." Jiang Xuan sighed and began to check the things in the box.

The most eye-catching thing in the box is a black metal object in the right direction.

It is not eye-catching because of its strong aura, but because it has no aura. Even if you don't use your naked eyes to see it, Jiang Xuan can't sense its existence with the secret technique. Moreover, it is an absolute square with a side length of about seven inches, which is slightly smaller than a human head.

This thing is obviously man-made.

But... what is the purpose of making a square?
