Following Chen Chen's arrival, two Black Knights posted beside the passage immediately stepped forward and saluted Chen Chen.
Chen Chen acknowledged them with a faint nod. After that, he heard a soft click of feet tapping against the ground. It was a female cyborg that emerged from the other end of the passage. She wore a floral dress and had an oddly-shaped mechanical device in her hand.
The mechanical device was shaped like a cube, almost like a Rubik's cube. What was notable was a hole in its center that had blue rays pouring out of it. From this opening at its center, it could be seen that this device contained something inside it that was emitting a blue glow continuously like a neon light.
The girl greeted Chen Chen sweetly, "Long time no see, Sir Commander, I'm X-112."
"Long time no see."
Chen Chen responded with a faint smile.
