Tumor Behind the Heart

If the maintenance worker or Ghost Assassin had turned around, he would have been able to clearly see that the latch on the inner side of the maintenance hatch had actually been lifted up inch by inch without anyone controlling it.

It was as if an invisible ghost had infiltrated the Golden Roc.

Fortunately, the worker was in a hurry to leave and did not turn back.

Also, since the Golden Roc was still under construction, people would often open and close the core cabin's maintenance hatch. The hinges, joints, and gears were all tightly fixed, making it extremely smooth. In addition, the liquid metallic material acted as a lubricant, so the hatch did not make any sound when it was opened.
