Who is that woman?

Musk had been observing everyone all this while until he saw a woman sitting by herself in the corner, her hand was holding some well-made cube, and looking at the gloves, she was wearing obviously she was someone from the crafting department. 

"Senior sister, why don't make some friends." As he spoke he approached the other party, he was more interested in the cube in her hand, as it seemed to shrink and expand in her hand. The skill she used to make this would be useful if he wanted to set up a powerful Ai, the bracelet he had on his hand, had stored the main data, but he did not have the confidence to fuse the other features into a storage space. 

It is better to have skills, and this person before him was already a target. When he moved all the peak masters seemed to be observing what he was going to do. But he just sat opposite the other party and said, "Hello senior sister, can I see the cube in your hand, it seems interesting."
